基于现有机制,当前小区的DCI(Downlink Control Information,下行控制信息)只允许调度一个小区的数据,例如调度PUSCH(Physical Uplink Shared Channel,物理上行共享信道)、PDSCH(Physical Downlink Shared Channel,物理下行共享信道)。Based on the existing mechanism, the current DCI (Downlink Control Information, downlink control information) of the current cell only allows scheduling of data of one cell, such as scheduling PUSCH (Physical Uplink Shared Channel, physical uplink shared channel), PDSCH (Physical Downlink Shared Channel, physical downlink shared channel).
而随着通信技术的发展,频率资源的逐步碎片化,通过跨载波调度(Cross-Carrier Scheduling CCS)的方式利用这些分散的频谱资源,从而实现更高的网络吞吐量和良好的覆盖范围。而通过单个DCI调度分散的频谱资源对应的多小区数据,可以有效降低DCI的payload开销,提升***容量。但是实现多个小区调度的单DCI的设计,目前并没有提出适当的解决方案。With the development of communication technology, frequency resources are gradually fragmented. These dispersed spectrum resources can be utilized through cross-carrier scheduling (CCS) to achieve higher network throughput and good coverage. Scheduling multi-cell data corresponding to dispersed spectrum resources through a single DCI can effectively reduce DCI payload overhead and improve system capacity. However, there is currently no appropriate solution proposed for the design of a single DCI that implements multiple cell scheduling.

For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be called second information, and similarly, the second information may also be called first information.

图1A是根据本公开的实施例示出的一种调度信息确定方法的示意流程图。本实施例所示的调度信息确定方法可以适用于终端,所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络设备通信,所述网络设备包括但不限于4G、5G、6G等通信***中的网络设备,例如基站、核心网等。FIG. 1A is a schematic flowchart of a method for determining scheduling information according to an embodiment of the present disclosure. The scheduling information determination method shown in this embodiment can be applied to terminals, which include but are not limited to mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices and other communication devices. The terminal can communicate with network equipment, which includes but is not limited to network equipment in 4G, 5G, 6G and other communication systems, such as base stations, core networks, etc.
如图1A所示,所述调度信息确定方法可以包括以下步骤:As shown in Figure 1A, the scheduling information determination method may include the following steps:
在步骤S101中,接收网络设备发送的用于调度多个小区的下行控制信息DCI(Downlink Control Information);In step S101, receive downlink control information DCI (Downlink Control Information) sent by the network device for scheduling multiple cells;
在步骤S102中,确定所述DCI中的相同类型的多个信息域与多个小区之间的关联关系;In step S102, determine the association between multiple information domains of the same type in the DCI and multiple cells;
在步骤S103中,根据每个所述信息域的值和所述关联关系,确定每个所述小区的调度信息。In step S103, the scheduling information of each cell is determined based on the value of each information field and the association relationship.
在一个实施例中,DCI中可以包括多种类型的信息域,例如FDRA(Frequency Domain Resource Assignment,频域资源分配)域、ZP CSI-RS trigger(Zero Power Channel Information Reference Signal trigger,零功率信道状态信息参考信号触发)域、部分带宽指示(BandWidth Part indicator)域等。In one embodiment, DCI may include multiple types of information domains, such as FDRA (Frequency Domain Resource Assignment, frequency domain resource allocation) domain, ZP CSI-RS trigger (Zero Power Channel Information Reference Signal trigger, zero power channel status Information reference signal trigger) field, partial bandwidth indicator (BandWidth Part indicator) field, etc.
对于现有机制的DCI,同一个类型的信息域,一般只包含一个,根据这个类型的信息域可以对一个小区进行调度,例如FDRA信息域可以调度目标小区的频域资源。For the DCI of the existing mechanism, the same type of information domain generally contains only one. A cell can be scheduled according to this type of information domain. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.
本实施例可以应用在一个DCI调度多个小区的场景中。在本实施例中,网络设备可以向终端发送DCI,用于调度多个小区,其中一种可能的设计方式如下:对于DCI内的一种或多种类型的信息域,对于多个小区,可以在DCI中设置相同类型的多个信息域,每个信息域可以针对其中一个小区进行调度。相同类型的信息域对应指示的信息类型相同,例如,指示不同小区的频域资源FDRA,例如,指示不同小区配置的BWP索引,具体可见下述描述。This embodiment can be applied in a scenario where one DCI schedules multiple cells. In this embodiment, the network device can send DCI to the terminal for scheduling multiple cells. One possible design method is as follows: for one or more types of information domains in the DCI, for multiple cells, Multiple information domains of the same type are set up in DCI, and each information domain can be scheduled for one of the cells. Information fields of the same type correspond to indicating the same type of information, for example, indicating frequency domain resources FDRA of different cells, for example, indicating BWP indexes configured in different cells. For details, see the following description.
这种指示方式可以称作分别separate方式,例如一个DCI中特定类型信息域可以包括多个信息域。可以在调度单个小区的一个DCI中信息域的基础上,根据小区的数目对特定类型信息域做对应比特bits的扩展,从而得到多个相同类型的信息域,其中不同的信息域指示不同小区的消息。一个DCI中多个相同类型信息域所占的bits数等于每个小区对应的上述信息域所占bits数的和。每个小区对应的上述信息域所占bits数与现有机制中,调度一个小区的DCI的相同类型信息域所占bits数相同。This indication method can be called a separate method. For example, a specific type of information field in a DCI can include multiple information fields. On the basis of scheduling the information field in a DCI of a single cell, the specific type of information field can be extended with corresponding bits according to the number of cells, thereby obtaining multiple information fields of the same type, where different information fields indicate the information of different cells. information. The number of bits occupied by multiple information fields of the same type in a DCI is equal to the sum of the number of bits occupied by the above information fields corresponding to each cell. The number of bits occupied by the above information field corresponding to each cell is the same as the number of bits occupied by the same type of information field used to schedule DCI of a cell in the existing mechanism.
图1B是根据本公开的实施例示出的一种调度信息确定方法的应用场景示意图。如图1B所示,以BWP指示域为例,在用于调度3个小区(小区id号分别为0、1和2)的一个DCI中,包括3个BWP指示域(BWP指示域#1、BWP指示域#2、BWP指示域#3),3个BWP指示域占用5bits,例如值为01100。FIG. 1B is a schematic diagram of an application scenario of a scheduling information determination method according to an embodiment of the present disclosure. As shown in Figure 1B, taking the BWP indication domain as an example, a DCI used to schedule three cells (cell ID numbers are 0, 1, and 2 respectively) includes three BWP indication domains (BWP indication domain #1, BWP indication field # 2, BWP indication field #3), the three BWP indication fields occupy 5 bits, for example, the value is 01100.
其中,第1个和第2个比特(01)可以作为BWP指示域#1对应小区0,那么可以根据第1个和第2个比特(01)确定小区0的BWP id=2;第3个和第4个比特(10)可以作为BWP指示域#2对应小区1,那么可以根据第3个和第4个比特(10)确定小区1的BWP id=3;第5个比特(0)可以作为BWP指示域#3对应小区0,那么可以根据第5个比特(0)确定小区2的BWP id=1。Among them, the 1st and 2nd bits (01) can be used as BWP indication field #1 corresponding to cell 0, then the BWP id=2 of cell 0 can be determined based on the 1st and 2nd bits (01); the 3rd and the 4th bit (10) can be used as the BWP indication field # 2 corresponding to cell 1, then the BWP id=3 of cell 1 can be determined based on the 3rd and 4th bits (10); the 5th bit (0) can As the BWP indication field # 3 corresponds to cell 0, the BWP id=1 of cell 2 can be determined based on the fifth bit (0).
所述3个BWP指示域占用的bits数等于所述3个小区BWP域所占bits数的和。对于特定小区对应的BWP域所占bits数基于现有机制确定,即,基于特定小区的高层配置BWP数量n
BWP,RRC确定特定小区对应的BWP域所占bits数。
The number of bits occupied by the three BWP indication domains is equal to the sum of the number of bits occupied by the three cell BWP domains. The number of bits occupied by the BWP domain corresponding to a specific cell is determined based on the existing mechanism, that is, the number of bits occupied by the BWP domain corresponding to the specific cell is determined based on the high-level configuration of the specific cell n BWP, and RRC determines the number of bits occupied by the BWP domain corresponding to the specific cell.
对于调度多个小区的DCI中特定类型的信息域,若特定类型的信息域采用separate方式,特定类型的信息域可以包括多个信息域,多个信息域占用比特bits对应索引为:
其中,索引1对应DCI特定类型信息域中的第一个bit,索引
为第1个信息域对应bits,用于指示小区k
0的调度信息,索引
为第j个信息域对应bits,用于指示小区k
j的调度信息,索引
为第n个信息域对应bits,用于指示小区k
n的调度信息,n等于小区数,其中k
j为小区id号。例如预定义规则可以规定n个信息域中第j个信息域与n个小区中的第j个小区相关联,其中,第j个小区的小区id可以为k
j。
For a specific type of information domain in DCI that schedules multiple cells, if the specific type of information domain adopts the separate mode, the specific type of information domain can include multiple information domains, and the corresponding index of the bits occupied by multiple information domains is: Among them, index 1 corresponds to the first bit in the DCI specific type information field, index Bits corresponding to the first information field, used to indicate the scheduling information of cell k 0 , index are the bits corresponding to the j-th information field, used to indicate the scheduling information of cell k j , index are the bits corresponding to the nth information field, used to indicate the scheduling information of cell k n , where n is equal to the number of cells, where k j is the cell ID number. For example, the predefined rule may stipulate that the j-th information domain among n information fields is associated with the j-th cell among n cells, where the cell ID of the j-th cell may be k j .
终端可以确定相同类型的多个信息域与多个小区之间的关联关系,进而根据关联关系确定每个信息域对应的小区,从而可以根据小区对应的信息域的值,确定小区的调度信息。从而在通过一个DCI对多个小区进行调度的基础上,准确地确定每个小 区的调度信息。The terminal can determine the association between multiple information domains of the same type and multiple cells, and then determine the cell corresponding to each information domain based on the association, so that the scheduling information of the cell can be determined based on the value of the information domain corresponding to the cell. Thus, on the basis of scheduling multiple cells through one DCI, the scheduling information of each cell can be accurately determined.
由于DCI中可以设置有多种类型的信息域,对于其中任意一种或几种类型,都可以采用separate的方式设置多个信息域来实现对多个小区的调度,具体针对哪种或哪几种类型设置多个信息域,可以根据预定义规则确定或根据信令指示确定。例如对于FDRA域和BWP指示域,信令指示FDRA域基于separate的方式指示,那么在DCI中可以针对多个小区,设置多个FDRA域;例如预定义规则规定针对FDAR域和BWP域都基于separate的方式指示,那么在DCI中可以针对多个小区,设置多个FDRA域以及多个BWP指示域。Since multiple types of information domains can be set in DCI, for any one or several types, multiple information domains can be set up in a separate manner to achieve scheduling of multiple cells, specifically for which one or several types. Multiple information fields are set for each type, which can be determined according to predefined rules or according to signaling instructions. For example, for the FDRA domain and the BWP indication domain, if the signaling indicates that the FDRA domain is based on separate indication, multiple FDRA domains can be set for multiple cells in the DCI; for example, the predefined rules stipulate that both the FDAR domain and the BWP domain are based on separate mode indication, then multiple FDRA domains and multiple BWP indication domains can be set for multiple cells in DCI.
需要说明的是,关于DCI所调度的多个小区的数量和/或多个小区对应的小区号,也即多个小区,终端可以根据DCI中的CIF(Cell Indicator Field,小区指示域)来确定,也可以是与网络设备预先约定的,还可以是根据预定义规则(例如协议约定)确定的,本公开并不限制。It should be noted that the terminal can determine the number of multiple cells scheduled by DCI and/or the cell numbers corresponding to the multiple cells, that is, multiple cells, based on the CIF (Cell Indicator Field) in the DCI. , may be pre-agreed with the network device, or may be determined based on predefined rules (such as protocol agreement), which is not limited by this disclosure.
在一个实施例中,所述关联关系中的多个小区为小区集合的多个小区,其中,所述小区集合包括以下至少之一:In one embodiment, the multiple cells in the association relationship are multiple cells in a cell set, wherein the cell set includes at least one of the following:
所述DCI所能调度的小区构成的小区集合;A set of cells composed of cells that can be scheduled by the DCI;
具有相同配置参数的小区构成的小区集合。A set of cells composed of cells with the same configuration parameters.
在这种情况下,用于调度多个小区的DCI中相同类型的信息域的数量,等于小区集合中小区的数量,从而对于某个类型的信息域而言,可以一一对应地实现对小区的指示。In this case, the number of information fields of the same type in the DCI used to schedule multiple cells is equal to the number of cells in the cell set. Therefore, for a certain type of information field, one-to-one correspondence can be achieved for cells. instructions.
在一个实施例中,所述关系中的多个小区可以属于一个小区集合,小区集合可以是用于调度多个小区的DCI所能调度的小区构成的小区集合。In one embodiment, multiple cells in the relationship may belong to a cell set, and the cell set may be a cell set composed of cells that can be scheduled by the DCI used to schedule multiple cells.
例如用于调度多个小区的DCI所能调度的小区为4个小区Cell#1、Cell#2、Cell#3、Cell#4,那么小区集合可以是{Cell#1、Cell#2、Cell#3、Cell#4}。For example, the DCI used to schedule multiple cells can schedule four cells: Cell#1, Cell# 2, Cell# 3, and Cell#4. Then the cell set can be {Cell#1, Cell# 2, Cell# 3. Cell#4}.
例如用于调度多个小区的DCI中相同类型的多个信息域的数量与所能调度的小区的数量相同,但是用于调度多个小区的DCI实际调度的小区的数量小于等于所能调度的小区的数量。那么对于相同类型的多个信息域中对应未调度小区的信息域,终端可以忽略;或者,对于相同类型的多个信息域中对应未调度小区的信息域的值,可以设置为预定义的值(例如,零填充),以便终端基于该预定义的值可以确定该信息域不用于指示调度信息。For example, the number of multiple information domains of the same type in the DCI used to schedule multiple cells is the same as the number of cells that can be scheduled, but the number of cells actually scheduled by the DCI used to schedule multiple cells is less than or equal to the number of cells that can be scheduled. The number of plots. Then, the terminal can ignore the information field corresponding to the unscheduled cell among the multiple information fields of the same type; or, the value of the information field corresponding to the unscheduled cell among the multiple information fields of the same type can be set to a predefined value. (for example, zero padding), so that the terminal can determine that the information field is not used to indicate scheduling information based on the predefined value.
多个信息域的数量与所能调度的小区的数量相同,均为4,用于调度多个小区的DCI实际调度的小区的数量为3,例如调度上述Cell#1、Cell#3、Cell#4,那么终端可以忽略4个信息域中与Cell#2对应的信息域filed#2,或者,网络设备可以将filed#2的值设置为预定义的值,终端根据filed#2的值可以确定filed#2不用于指示调度信息。The number of multiple information fields is the same as the number of cells that can be scheduled, which is 4. The number of cells actually scheduled by the DCI used to schedule multiple cells is 3. For example, the above-mentioned Cell#1, Cell# 3, and Cell# are scheduled. 4, then the terminal can ignore the information field filed#2 corresponding to Cell# 2 among the 4 information fields, or the network device can set the value of filed#2 to a predefined value, and the terminal can determine it based on the value of filed#2 filed#2 is not used to indicate scheduling information.
在一个实施例中,所述关系中的多个小区可以属于一个小区集合,小区集合可以具有相同配置参数的小区构成的小区集合。其中,所述配置参数包括但不限于集合标识、小区标识、序号、载波指示域(Carrier Indicator Field,CIF);In one embodiment, multiple cells in the relationship may belong to a cell set, and the cell set may be a cell set composed of cells with the same configuration parameters. Wherein, the configuration parameters include but are not limited to aggregation identification, cell identification, sequence number, and carrier indicator field (Carrier Indicator Field, CIF);
例如以4个小区Cell#1、Cell#2、Cell#3、Cell#4,配置参数包括CIF为例,可以确定为这4个小区中每个小区配置的CIF(例如根据无线资源控制RRC信令确定)。例如为Cell#1配置的CIF为01,为Cell#2配置的CIF为01,为Cell#3配置的CIF为02,为Cell#4配置的CIF为02,那么可以确定Cell#1和Cell#2具有相同的CIF,Cell#3和Cell#4具有相同的CIF,从而将Cell#1和Cell#2划分为一个用于调度多个小区的下行控制信息对应的小区集合{Cell#1、Cell#2},将Cell#3和Cell#4划分为另一个用于调度多个小区的下行控制信息对应的小区集合{Cell#3、Cell#4}。For example, taking four cells, Cell#1, Cell# 2, Cell# 3, and Cell#4, and the configuration parameters include CIF, the CIF configured for each of the four cells can be determined (for example, according to the radio resource control RRC signal Order to confirm). For example, the CIF configured for Cell#1 is 01, the CIF configured for Cell# 2 is 01, the CIF configured for Cell# 3 is 02, and the CIF configured for Cell#4 is 02, then you can determine Cell#1 and Cell# 2 has the same CIF, Cell# 3 and Cell#4 have the same CIF, thus dividing Cell#1 and Cell# 2 into a cell set corresponding to the downlink control information for scheduling multiple cells {Cell#1, Cell #2}, divide Cell# 3 and Cell#4 into another cell set {Cell# 3, Cell#4} that is used to schedule downlink control information of multiple cells.
在一个实施例中,所述方法还包括:In one embodiment, the method further includes:
根据所述网络设备发送的信令和/或预定义规则确定所述小区集合。The cell set is determined according to signaling sent by the network device and/or predefined rules.
所述小区集合可以是网络设备通过信令指示的,其中,所述信令包括但不限于RRC信令、DCI、MAC CE等。所述小区集合也可以是基于预定义规则确定的,例如预定义规则为具有相同配置参数的小区属于同一小区集合,那么可以确定小区的配置参数,并将具有相同配置参数的小区确定为属于同一小区集合。The cell set may be indicated by the network device through signaling, where the signaling includes but is not limited to RRC signaling, DCI, MAC CE, etc. The cell set can also be determined based on predefined rules. For example, the predefined rule is that cells with the same configuration parameters belong to the same cell set. Then the configuration parameters of the cells can be determined, and the cells with the same configuration parameters can be determined as belonging to the same cell set. Community gathering.
在一个实施例中,所述小区集合包含的小区包括以下至少之一:In one embodiment, the cells included in the cell set include at least one of the following:
调度小区;dispatching area;
被调度小区。The scheduled cell.
例如,小区集合可以包含被调度小区,也即用于调度多个小区的DCI调度的小区;例如,小区集合可以包含调度小区,也即终端接收用于调度多个小区的DCI时所在的小区;例如,小区集合可以包括调度小区和被调度小区。For example, the cell set may include scheduled cells, that is, cells used for scheduling DCI scheduling of multiple cells; for example, the cell set may include scheduling cells, that is, the cells where the terminal is located when receiving DCI used for scheduling multiple cells; For example, a cell set may include a scheduling cell and a scheduled cell.
需要说明的是,调度小区和被调度小区,都可以属于用于调度多个小区的DCI所能调度的小区。It should be noted that both the scheduling cell and the scheduled cell may belong to cells that can be scheduled by the DCI used to schedule multiple cells.
在一个实施例中,所述关联关系中多个信息域的数量,等于所述DCI所能调度的最大小区数量。In one embodiment, the number of multiple information fields in the association relationship is equal to the maximum number of cells that can be scheduled by the DCI.
在一个实施例中,用于调度多个小区的DCI,每次所调度的多个小区可以是不同的,终端可以根据网络设备发送的指示信息,或者根据预定义规则(例如协议约定)确定用于调度多个小区的DCI每次所调度的多个小区。In one embodiment, the DCI used to schedule multiple cells may be different each time. The terminal may determine the user according to the instruction information sent by the network device or according to predefined rules (such as protocol agreement). The DCI for scheduling multiple cells schedules multiple cells at a time.
以根据网络设备发送的指示信息确定用于调度多个小区的DCI每次所调度的多个小区为例,网络设备可以向终端发送指示信息与调度多个小区的DCI每次所调度的多个小区之间的对应关系(例如可以为表格形式,可以携带在RRC信令中发送给终端)。终端在接收到用于调度多个小区的DCI时,可以在对应关系中确定网络设备发送的指示信息(例如携带在所述DCI中,或者携带在其他信令中)指示所述DCI调度的多个小区。终端还可以根据对应关系确定DCI所能调度的最大小区数量,也即对应关系中,指示信息所指示的DCI调度最多小区时小区的数量。Taking the example of determining the multiple cells that are scheduled each time by the DCI for scheduling multiple cells based on the instruction information sent by the network device, the network device can send the instruction information to the terminal along with the multiple cells that are scheduled by the DCI that schedules multiple cells each time. Correspondence between cells (for example, it can be in the form of a table and can be carried in RRC signaling and sent to the terminal). When receiving DCI for scheduling multiple cells, the terminal may determine in the corresponding relationship that the instruction information sent by the network device (for example, carried in the DCI or carried in other signaling) indicates that the DCI schedules multiple cells. A community. The terminal can also determine the maximum number of cells that can be scheduled by DCI according to the corresponding relationship, that is, in the corresponding relationship, the number of cells when the DCI indicated by the indication information schedules the most cells.
例如对应关系包括:指示信息为1,DCI调度的多个小区为Cell#1、Cell#2;指示信息为2,DCI调度的多个小区为Cell#3、Cell#4;指示信息为3,DCI调度的多个小区为Cell#1、Cell#2、Cell#4。那么终端可以确定DCI所能调度的最大小区数量为3,进而可以确定DCI中相同类型的多个信息域的数量也为3。For example, the corresponding relationship includes: the indication information is 1, and the multiple cells scheduled by DCI are Cell#1 and Cell# 2; the indication information is 2, and the multiple cells scheduled by DCI are Cell# 3 and Cell#4; the indication information is 3, The multiple cells scheduled by DCI are Cell#1, Cell# 2, and Cell#4. Then the terminal can determine that the maximum number of cells that can be scheduled by DCI is 3, and further can determine that the number of multiple information domains of the same type in DCI is also 3.
后续终端在接收到用于调度多个小区的DCI时,可以先确定DCI实际调度小区的数量。若DCI实际调度小区的数量等于相同类型的多个信息域的数量,那么可以根据DCI实际调度小区的标识从小到大(或从大到小)与多个信息域相对应,确定每个信息域所指示的小区。When a subsequent terminal receives DCI for scheduling multiple cells, it can first determine the number of cells actually scheduled by the DCI. If the number of cells actually scheduled by DCI is equal to the number of multiple information domains of the same type, then each information domain can be determined based on the identification of the cells actually scheduled by DCI corresponding to the multiple information domains from small to large (or from large to small). the indicated neighborhood.
例如DCI实际调度的小区为Cell#1、Cell#2、Cell#4,那么可以确定第一个信息域用于针对Cell#1进行指示,第二个信息域用于针对Cell#2进行指示,第三个信息域用于针对Cell#4进行指示。For example, the cells actually scheduled by DCI are Cell#1, Cell# 2, and Cell#4. Then it can be determined that the first information field is used to indicate Cell#1, and the second information field is used to indicate Cell# 2. The third information field is used to indicate Cell#4.
若DCI实际调度小区的数量小于相同类型的多个信息域的数量,那么可以根据DCI实际调度小区的标识从小到大(或从大到小)与多个信息域相对应,确定每个信息域所指示的小区,并针对未对应的信息域设置为预定义的值,以便终端基于该预定义的值可以确定该信息域不用于针对小区进行指示;或者,针对未对应的信息域可以设置为预留位(reserved),以便终端基于预留位可以确定该信息域不用于针对小区进行指示。If the number of cells actually scheduled by DCI is less than the number of multiple information domains of the same type, then each information domain can be determined based on the identification of the cells actually scheduled by DCI corresponding to the multiple information domains from small to large (or from large to small). The indicated cell, and set to a predefined value for the uncorresponding information field, so that the terminal can determine based on the predefined value that the information field is not used to indicate the cell; or, for the uncorresponding information field, it can be set to Reserved bits (reserved), so that the terminal can determine based on the reserved bits that this information field is not used to indicate the cell.
例如根据DCI实际调度小区的标识从小到大与多个信息域相对应,DCI实际调度的小区为Cell#1、Cell#2。若从多个信息域的第一个信息域开始对应,那么可以确定最后一个信息域未对应,那么可以确定第一个信息域用于针对Cell#1进行指示,第二个信息域用于针对Cell#2进行指示,第三个信息域为预定义的值;若从多个信息域的最后一个信息域开始对应,那么可以确定第一个信息域未对应,那么可以确定第三个信息域用于针对Cell#1进行指示,第二个信息域用于针对Cell#2进行指示,第一个信息域为预定义的值。For example, the identifiers of cells actually scheduled by DCI correspond to multiple information fields from small to large, and the cells actually scheduled by DCI are Cell#1 and Cell# 2. If the correspondence starts from the first information field of multiple information fields, then it can be determined that the last information field is not corresponding, then it can be determined that the first information field is used to indicate Cell#1, and the second information field is used to indicate Cell#1. Cell# 2 indicates that the third information field is a predefined value; if the correspondence starts from the last information field of multiple information fields, then it can be determined that the first information field is not corresponding, then the third information field can be determined It is used to indicate Cell#1, the second information field is used to indicate Cell# 2, and the first information field is a predefined value.
例如根据DCI实际调度小区的标识从大到小与多个信息域相对应,DCI实际调度的小区为Cell#1、Cell#2。若从多个信息域的第一个信息域开始对应,那么可以确定最后一个信息域未对应,那么可以确定第一个信息域用于针对Cell#2进行指示,第二个信息域用于针对Cell#1进行指示,第三个信息域为预定义的值;若从多个信息域的最后一个信息域开始对应,那么可以确定第一个信息域未对应,那么可以确定第三个信息域用于针对Cell#2进行指示,第二个信息域用于针对Cell#1进行指示,第一个信息域为预定义的值。For example, the identifiers of the cells actually scheduled by the DCI correspond to multiple information fields from large to small, and the cells actually scheduled by the DCI are Cell#1 and Cell# 2. If the correspondence starts from the first information field of multiple information fields, then it can be determined that the last information field is not corresponding, then it can be determined that the first information field is used to indicate Cell # 2, and the second information field is used to indicate Cell # 2. Cell#1 indicates that the third information field is a predefined value; if the correspondence starts from the last information field of multiple information fields, then it can be determined that the first information field is not corresponding, then the third information field can be determined It is used to indicate Cell# 2, the second information field is used to indicate Cell#1, and the first information field is a predefined value.
在一个实施例中,所述确定所述DCI中的相同类型的多个信息域与多个小区之间的关联关系包括:根据预定义规则确定所述关联关系。In one embodiment, determining the association relationship between multiple information domains of the same type in the DCI and multiple cells includes: determining the association relationship according to predefined rules.
在一个实施例中,所述确定所述DCI中的相同类型的多个信息域与多个小区之间的关联关系包括:根据网络设备的指示确定所述关联关系。In one embodiment, determining the association between multiple information domains of the same type in the DCI and multiple cells includes: determining the association according to instructions from a network device.
DCI中的相同类型的多个信息域与多个小区之间的关联关系可以是预定义规则规定的,例如协议约定的;也可以是由网络设备指示的,其中,网络设备指示所述关联关系的方式包括但不限于通过RRC(Radio Resource Control,无线资源控制)信令进行指示、通过DCI进行指示、通过MAC CE(Media Access Control Control Element,媒体接入控制控制元素)进行指示。The association between multiple information domains of the same type in DCI and multiple cells may be stipulated by predefined rules, such as agreed upon by a protocol; it may also be indicated by a network device, where the network device indicates the association. The methods include but are not limited to indicating through RRC (Radio Resource Control, Radio Resource Control) signaling, indicating through DCI, and indicating through MAC CE (Media Access Control Control Element, Media Access Control Element).
以下实施例主要针对预定义规则规定所述关联关系的情况进行示例性说明。The following embodiments mainly illustrate the case where the association relationship is stipulated by predefined rules.
在一个实施例中,所述多个信息域包括n个信息域,所述多个小区包括n个小区;所述预定义规则规定所述n个信息域中第j个信息域与所述n个小区中的第j个小区相关联,其中,1≤j≤n。In one embodiment, the plurality of information domains includes n information domains, and the plurality of cells includes n cells; the predefined rule stipulates that the jth information domain among the n information domains is the same as the n information domain. The j-th cell among the cells is associated, where 1≤j≤n.
多个小区可以包括终端接收所述DCI时所在小区以及其他小区(终端接收所述DCI时所在小区以外的小区),也可以不包括终端接收所述DCI时所在小区,仅包括 其他小区。本实施中预定义规则在规定小区与信息域之间的关联关系时,可以不区分终端接收所述DCI时所在小区以及其他小区,按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。Multiple cells may include the cell where the terminal is located when receiving the DCI and other cells (cells other than the cell where the terminal is receiving the DCI), or may not include the cell where the terminal is located when receiving the DCI, and may only include other cells. When the predefined rules in this implementation stipulate the association between the cell and the information domain, the cell where the terminal receives the DCI and other cells may not be distinguished. The same rules stipulate that the cell where the terminal receives the DCI and other cells and The relationship between information domains.
以n个小区为例,针对某个类型的信息域,可以设置n个信息域来对这n个小区进行调度,关联关系可以是n个信息域中第j个信息域与n个小区中第j个小区相关联。Taking n cells as an example, for a certain type of information domain, n information domains can be set to schedule the n cells. The association relationship can be the j-th information domain among the n information domains and the j-th information domain among the n cells. j cells are associated.
据此,终端可以确定第j个信息域的值所指示的调度信息为第j个小区的调度信息,从而在通过一个DCI对多个小区进行调度的基础上,准确地确定每个小区的调度信息。所述第j个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。Accordingly, the terminal can determine that the scheduling information indicated by the value of the j-th information field is the scheduling information of the j-th cell, thereby accurately determining the scheduling of each cell based on scheduling multiple cells through one DCI. information. The number of bits occupied by the jth information domain and the specific indication method are the same as the single DCI scheduling single cell method.
例如针对第1个小区至第n个小区这n个小区,以FDRA域采用separate指示方式为例,在DCI中可以设置n个FDRA域,预定义规则可以规定n个信息域中第j个信息域与n个小区中的第j个小区相关联,其中,第j个小区的小区id可以为k
j。在本实施例中,终端可以确定第1个FDRA域指示第1个小区(小区k
1)的频域调度信息、第2个FDRA域指示第2个小区(小区k
2)的频域调度信息、…、第j个FDRA域指示第j个小区(小区k
j)的频域调度信息、…、第n个FDRA域指示第n个小区(小区k
n)的频域调度信息,从而在通过一个DCI对多个小区进行调度的基础上,使得终端可以准确地解读DCI指示的每个小区的频域调度信息。
For example, for n cells from the 1st cell to the nth cell, taking the FDRA domain using the separate indication method as an example, n FDRA domains can be set in the DCI, and the predefined rules can specify the j-th information in the n information domains. The domain is associated with the j-th cell among the n cells, where the cell id of the j-th cell may be k j . In this embodiment, the terminal can determine that the first FDRA domain indicates the frequency domain scheduling information of the first cell (cell k 1 ), and the second FDRA domain indicates the frequency domain scheduling information of the second cell (cell k 2 ). ,..., the jth FDRA domain indicates the frequency domain scheduling information of the jth cell (cell k j ),..., the nth FDRA domain indicates the frequency domain scheduling information of the nth cell (cell k n ), so that when passing On the basis that one DCI schedules multiple cells, the terminal can accurately interpret the frequency domain scheduling information of each cell indicated by the DCI.
所述第j个FDRA域所占bits数根据通信协议38.212[2]中的机制确定,即:基于第j个小区的高层配置信令指示的资源分配类型(‘type 0’,‘type 1’,‘dynamic’)确定所述第j个FDRA域所占bits以及FDRA域指示的value与频域资源的对应关系。The number of bits occupied by the j-th FDRA domain is determined according to the mechanism in the communication protocol 38.212 [2], that is: based on the resource allocation type indicated by the high-level configuration signaling of the j-th cell ('type 0', 'type 1' ,'dynamic') determines the corresponding relationship between the bits occupied by the j-th FDRA domain and the value indicated by the FDRA domain and the frequency domain resource.
例如针对第1个小区至第n个小区这n个小区,以ZP CSI-RS trigger域采用separate指示方式为例,在DCI中可以设置n个ZP CSI-RS trigger域,预定义规则可以规定n个信息域中第j个信息域与n个小区中的第j个小区相关联,其中,第j个小区的小区id可以为k
j。在本实施例中,终端可以确定第1个ZP CSI-RS trigger域指示第1个小区(小区k
1)的ZP CSI-RS trigger信息、第2个ZP CSI-RS trigger域指示第2个小区(小区k
2)的ZP CSI-RS trigger信息、…、第j个ZP CSI-RS trigger域指示第j个小区(小区k
j)的ZP CSI-RS trigger信息、…、第n个ZP CSI-RS trigger域指示第n个小区(小区k
n)的ZP CSI-RS trigger信息,从而在通过一个DCI对多个小区进行 调度的基础上,使得终端可以准确地解读DCI指示的每个小区的ZP CSI-RS trigger信息。
For example, for n cells from the 1st cell to the nth cell, taking the ZP CSI-RS trigger field using the separate indication method as an example, n ZP CSI-RS trigger fields can be set in DCI, and the predefined rules can specify n The j-th information domain among the information domains is associated with the j-th cell among the n cells, where the cell id of the j-th cell may be k j . In this embodiment, the terminal can determine that the first ZP CSI-RS trigger field indicates the ZP CSI-RS trigger information of the first cell (cell k 1 ), and the second ZP CSI-RS trigger field indicates the second cell The ZP CSI-RS trigger information of (cell k 2 ), ..., the j-th ZP CSI-RS trigger field indicates the ZP CSI-RS trigger information of the j-th cell (cell k j ), ..., the n-th ZP CSI- The RS trigger field indicates the ZP CSI-RS trigger information of the nth cell (cell k n ), so that on the basis of scheduling multiple cells through one DCI, the terminal can accurately interpret the ZP of each cell indicated by the DCI. CSI-RS trigger information.
所述第j个ZP CSI-RS trigger域所占bits数根据通信协议38.212[2]中的机制确定,即:基于第j个小区的高层配置ZP CSI-RS资源集数量n
ZP确定第j个ZP CSI-RS trigger域所占bits数。
The number of bits occupied by the j-th ZP CSI-RS trigger domain is determined according to the mechanism in communication protocol 38.212 [2], that is: based on the high-level configuration of the j-th cell ZP CSI-RS resource set number n ZP determines the j-th Number of bits occupied by the ZP CSI-RS trigger domain.
例如针对第1个小区至第n个小区这n个小区,以BWP指示域采用separate指示方式为例,在DCI中可以设置n个BWP指示域,预定义规则可以规定n个信息域中第j个信息域与n个小区中的第j个小区相关联,其中,第j个小区的小区id可以为k
j。在本实施例中,终端可以确定第1个BWP指示域指示第1个小区(小区k
1)的BWP信息、第2个BWP指示域指示第2个小区(小区k
2)的BWP信息、…、第j个BWP指示域指示第j个小区(小区k
j)的BWP信息、…、第n个BWP指示域指示第n个小区(小区k
n)的BWP信息,从而在通过一个DCI对多个小区进行调度的基础上,使得终端可以准确地解读DCI指示的每个小区的BWP信息。
For example, for n cells from the 1st cell to the nth cell, taking the BWP indication field using the separate indication method as an example, n BWP indication fields can be set in DCI, and the predefined rules can specify the jth of the n information fields. The information domain is associated with the j-th cell among the n cells, where the cell id of the j-th cell may be k j . In this embodiment, the terminal can determine that the first BWP indication field indicates the BWP information of the first cell (cell k 1 ), the second BWP indication field indicates the BWP information of the second cell (cell k 2 ), ... , the jth BWP indication field indicates the BWP information of the jth cell (cell k j ),..., the nth BWP indication field indicates the BWP information of the nth cell (cell k n ), so that through one DCI to multiple Scheduling is performed on each cell, so that the terminal can accurately interpret the BWP information of each cell indicated by the DCI.
所述第j个BWP域所占bits数根据通信协议38.212[2]中的机制确定,即:基于第j个小区的高层配置BWP数量n
BWP,RRC确定第j个BWP域所占bits数。
The number of bits occupied by the j-th BWP domain is determined according to the mechanism in communication protocol 38.212 [2], that is, based on the high-level configuration BWP number n BWP of the j-th cell, RRC determines the number of bits occupied by the j-th BWP domain.
其中,关于多个信息域的顺序,可以按照多个信息域占用比特bit的顺序从前到后以此确定,也即第j个信息域占用的比特在第j+1个信息域占用的比特之前。而关于多个小区的顺序,在后续实施例中说明如何确定。Among them, the order of the multiple information fields can be determined from front to back according to the order of the bits occupied by the multiple information fields, that is, the bits occupied by the jth information field are before the bits occupied by the j+1th information field. . Regarding the order of multiple cells, how to determine it will be described in subsequent embodiments.
需要说明的是,对于相同类型的多个信息域,每个信息域对应比特的数量可以相同,也可以不同,还可以为0,具体可以根据通信协议38.212[2]中的机制确定,本公开在此不作赘述。It should be noted that for multiple information fields of the same type, the number of corresponding bits for each information field can be the same, different, or 0. The details can be determined according to the mechanism in the communication protocol 38.212 [2]. This disclosure No further details will be given here.
以相同类型的4个信息域占用8个比特为例,若信息域对应比特的数量存在不同,那么可以是第1个信息域对应第1和第2个比特(即比特索引
对应2个比特),第2个信息域对应第3至第5个比特(即比特索引
对应3个比特),第3个信息域对应第6和第7个比特(即比特索引
对应2个比特),第4个信息域对应第8个比特(即比特索引
对应1个比特);若信息域对应比特的数量相同,那么可以是第1个信息域对应第1和第2个比特,第2个信息域对应第3和第4个比特,第3个信息域对应第5和第6个比特,第4个信息域对应第7和 第8个比特,也即每个信息域对应2个比特(即比特索引
对应2个比特)。
Taking 4 information fields of the same type occupying 8 bits as an example, if the number of corresponding bits in the information fields is different, then the first information field can correspond to the 1st and 2nd bits (i.e. bit index Corresponding to 2 bits), the second information field corresponds to the 3rd to 5th bits (i.e. bit index Corresponding to 3 bits), the third information field corresponds to the 6th and 7th bits (i.e. bit index Corresponding to 2 bits), the 4th information field corresponds to the 8th bit (i.e. bit index Corresponding to 1 bit); if the information fields correspond to the same number of bits, then the first information field can correspond to the 1st and 2nd bits, the second information field corresponds to the 3rd and 4th bits, and the 3rd information field The field corresponds to the 5th and 6th bits, and the 4th information field corresponds to the 7th and 8th bits, that is, each information field corresponds to 2 bits (i.e., bit index corresponds to 2 bits).
以下通过几个实施例示例性说明,预定义规则按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系,以及如何确定多个小区的顺序。The following is an illustrative description through several embodiments. The predefined rules specify the association between the cell where the terminal is located when receiving the DCI and other cells and the information domain according to the same rules, and how to determine the order of multiple cells.
在一个实施例中,所述预定义规则规定第j个小区的标识小于第j+1个小区的标识,也即k
j小于k
j+1;或者,所述预定义规则规定第j个小区的标识大于第j+1个小区的标识,也即k
j大于k
j+1。
In one embodiment, the predefined rule stipulates that the identity of the j-th cell is less than the identity of the j+1-th cell, that is, k j is less than k j+1 ; or, the pre-defined rule stipulates that the j-th cell The identity of is greater than the identity of j+1th cell, that is, k j is greater than k j+1 .
关于小区的标识(例如Cell ID),终端可以根据网络设备发送的RRC信令确定,例如根据RRC信令中的ServcellIndex和/或SCellIndex等信息元素(Information Element,IE)确定;而若小区的标识对应PCI(Physical Cell Identity,物理小区标识),那么可以根据RRC信令中的信息元素PhysCellId确定;当然,也可以根据其他信令确定。或者,根据其他方式确定,例如可以为预定义规则规定的。Regarding the identity of the cell (such as Cell ID), the terminal can determine it based on the RRC signaling sent by the network device, for example, based on the information elements (Information Element, IE) such as ServcellIndex and/or SCellIndex in the RRC signaling; and if the identity of the cell Corresponding to PCI (Physical Cell Identity, physical cell identity), it can be determined based on the information element PhysCellId in RRC signaling; of course, it can also be determined based on other signaling. Or, determined in other ways, such as may be specified by predefined rules.
预定义规则可以根据小区的标识对小区进行排序,例如可以按照标识由小到大进行排序,那么第j个小区的标识小于第j+1个小区的标识,或者可以按照标识由大到小进行排序,那么第j个小区的标识大于第j+1个小区的标识。The predefined rules can sort the cells according to their identities. For example, they can sort them from small to large, so that the identity of the j-th cell is smaller than the identity of the j+1th cell, or they can sort them from large to small. Sorting, then the identity of the j-th cell is greater than the identity of the j+1-th cell.
例如以4个小区为例,分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4。若按照标识由小到大排序,那么k
j小于k
j+1,可以确定第1个小区为小区#1,第2个小区为小区#2,第3个小区为小区#3,第4个小区为小区#4;若按照标识由大到小排序,那么k
j大于k
j+1,可以确定第1个小区为小区#4,第2个小区为小区#3,第3个小区为小区#2,第4个小区为小区#1。
For example, taking four cells as an example, they are cell #1 with an identifier of 1, cell # 2 with an identifier of 2, cell # 3 with an identifier of 3, and cell #4 with an identifier of 4. If the identifiers are sorted from small to large, then k j is less than k j+1 , it can be determined that the first cell is cell #1, the second cell is cell # 2, the third cell is cell # 3, and the fourth cell is cell # 3. The cell is cell #4; if the identifiers are sorted from large to small, then k j is greater than k j+1 , it can be determined that the first cell is cell #4, the second cell is cell # 3, and the third cell is cell # 2, the 4th cell is cell #1.
据此,可以根据小区的标识准确地确定小区的排序,进而可以第j个信息域调度的第j个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined based on the identities of the cells, and further, which cell is the j-th cell scheduled in the j-th information domain.
在一个实施例中,所述预定义规则规定第j个小区的中心频率小于第j+1个小区的中心频率;或者,所述预定义规则规定第j个小区的中心频率大于第j+1个小区的中心频率。In one embodiment, the predefined rule stipulates that the center frequency of the jth cell is less than the center frequency of the j+1th cell; or, the predefined rule stipulates that the center frequency of the jth cell is greater than the j+1th cell. The center frequency of a cell.
关于小区的中心频率,终端可以根据网络设备发送的信息确定,例如根据网络设备发送的同步信号块SSB(Synchronization Signal Block)确定;当然,也可以根据其他方式确定,例如可以为预定义规则规定的。Regarding the center frequency of the cell, the terminal can determine it based on the information sent by the network device, such as the synchronization signal block SSB (Synchronization Signal Block) sent by the network device; of course, it can also be determined based on other methods, such as predefined rules. .
预定义规则可以根据小区的中心频率对小区进行排序,例如可以按照中心频率由小到大进行排序,那么第j个小区的中心频率小于第j+1个小区的中心频率,或者可以按照中心频率由大到小进行排序,那么第j个小区的中心频率大于第j+1个小区的中心频率。The predefined rules can sort the cells according to the center frequency of the cell. For example, the center frequency can be sorted from small to large. Then the center frequency of the j-th cell is smaller than the center frequency of the j+1-th cell, or the center frequency can be sorted according to the center frequency. Sorting from large to small, then the center frequency of the j-th cell is greater than the center frequency of the j+1-th cell.
例如以4个小区为例,小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4,其中,f1>f2>f3>f4。若按照中心频率由小到大排序,那么第1个小区为小区#4,第2个小区为小区#3,第3个小区为小区#2,第4个小区为小区#1;若按照中心频率由大到小排序,那么第1个小区为小区#1,第2个小区为小区#2,第3个小区为小区#3,第4个小区为小区#4。For example, taking four cells as an example, the center frequency of cell #1 is f1, the center frequency of cell # 2 is f2, the center frequency of cell # 3 is f3, and the center frequency of cell #4 is f4, where f1>f2> f3>f4. If sorted according to the center frequency from small to large, then the first cell is cell #4, the second cell is cell # 3, the third cell is cell # 2, and the fourth cell is cell #1; if according to the center frequency The frequencies are sorted from large to small, then the first cell is cell #1, the second cell is cell # 2, the third cell is cell # 3, and the fourth cell is cell #4.
据此,可以根据小区的中心频率准确地确定小区的排序,进而可以第j个信息域调度的第j个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined according to the center frequency of the cells, and further, which cell is the j-th cell scheduled in the j-th information domain.
在一个实施例中,所述预定义规则规定第j个小区的中心频率对应的ARFCN(Absolute Radio Frequency Channel Number,绝对无线频率信道编号,具体可以是NR-ARFCN)小于第j+1个小区的中心频率对应的ARFCN;或者,所述预定义规则规定第j个小区的中心频率对应的ARFCN大于第j+1个小区的中心频率对应的ARFCN。In one embodiment, the predefined rule stipulates that the ARFCN (Absolute Radio Frequency Channel Number, absolute radio frequency channel number, specifically NR-ARFCN) corresponding to the center frequency of the j-th cell is smaller than that of the j+1-th cell. The ARFCN corresponding to the center frequency; or, the predefined rule stipulates that the ARFCN corresponding to the center frequency of the j-th cell is greater than the ARFCN corresponding to the center frequency of the j+1-th cell.
关于小区的ARFCN,终端可以根据小区的中心频率确定,也可以通过其他方式确定。Regarding the ARFCN of the cell, the terminal can determine it according to the center frequency of the cell or by other methods.
预定义规则可以根据小区的ARFCN对小区进行排序,例如可以按照ARFCN由小到大进行排序,那么第j个小区的ARFCN小于第j+1个小区的ARFCN,或者可以按照ARFCN由大到小进行排序,那么第j个小区的ARFCN大于第j+1个小区的ARFCN。The predefined rules can sort the cells according to their ARFCN. For example, they can sort from small to large ARFCN, then the ARFCN of the jth cell is smaller than the ARFCN of the j+1th cell, or they can sort according to ARFCN from large to small. Sorting, then the ARFCN of the j-th cell is greater than the ARFCN of the j+1-th cell.
例如以4个小区为例,小区#1的ARFCN为ARFCN#1、小区#2的ARFCN为ARFCN#2、小区#3的ARFCN为ARFCN#3、小区#4的ARFCN为ARFCN#4,其中,ARFCN#1>ARFCN#2>ARFCN#3>ARFCN#4。若按照ARFCN由小到大排序,那么第1个小区为小区#4,第2个小区为小区#3,第3个小区为小区#2,第4个小区为小区#1;若按照ARFCN由大到小排序,那么第1个小区为小区#1,第2个小区为小区#2,第3个小区为小区#3,第4个小区为小区#4。For example, taking 4 cells as an example, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell # 2 is ARFCN# 2, the ARFCN of cell # 3 is ARFCN# 3, and the ARFCN of cell #4 is ARFCN#4, where, ARFCN#1>ARFCN# 2>ARFCN# 3>ARFCN#4. If sorted according to ARFCN from small to large, then the first cell is cell #4, the second cell is cell # 3, the third cell is cell # 2, and the fourth cell is cell #1; if according to ARFCN by Sorting from large to small, then the first cell is cell #1, the second cell is cell # 2, the third cell is cell # 3, and the fourth cell is cell #4.
据此,可以根据小区的ARFCN准确地确定小区的排序,进而可以第j个信息域调度的第j个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined according to the ARFCN of the cells, and further, which cell is the jth cell scheduled in the jth information domain.
在一个实施例中,所述多个信息域包括n个信息域,所述多个小区包括终端接收所述DCI时所在小区以及n-1个其他小区;所述预定义规则规定所述n个信息域中的第1个信息域与终端接收所述DCI时所在小区相关联,第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联,其中,2≤i≤n。In one embodiment, the multiple information domains include n information domains, and the multiple cells include the cell where the terminal is located when receiving the DCI and n-1 other cells; the predefined rules specify that the n The first information domain in the information domain is associated with the cell where the terminal is located when receiving the DCI, and the i-th information domain among the second to n-th information domains is associated with the i-th information domain in the n-1 other cells. i-1 other cells are associated, where 2≤i≤n.
多个小区可以包括终端接收所述DCI时所在小区以及其他小区(终端接收所述DCI时所在小区以外的小区),也可以不包括终端接收所述DCI时所在小区,仅包括其他小区。本实施中预定义规则在规定小区与信息域之间的关联关系时,可以区分终端接收所述DCI时所在小区以及其他小区,按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。The multiple cells may include the cell where the terminal is located when receiving the DCI and other cells (cells other than the cell where the terminal is receiving the DCI), or may not include the cell where the terminal is located when receiving the DCI and only include other cells. The predefined rules in this implementation can distinguish the cell where the terminal is located when receiving the DCI and other cells when stipulating the association between the cell and the information domain, and stipulate the cell where the terminal is located when receiving the DCI and other cells and information according to different rules. The relationship between domains.
以n个小区为例,若所述n个小区包括终端接收所述DCI时所在小区以及n-1个其他小区。针对某个类型的信息域,可以设置n个信息域来对这n个小区进行调度,关联关系可以为n个信息域中的第1个信息域与终端接收所述DCI时所在小区相关联,第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联。也即对于n-1个其他小区,按照相同规则规定小区与信息域之间的关联关系,而对于终端接收所述DCI时所在小区,则规定与第1个信息域相关联。Taking n cells as an example, if the n cells include the cell where the terminal receives the DCI and n-1 other cells. For a certain type of information domain, n information domains can be set to schedule the n cells. The association relationship can be that the first information domain among the n information domains is associated with the cell where the terminal receives the DCI. The i-th information domain among the second to n-th information domains is associated with the i-1th other cell among the n-1 other cells. That is, for n-1 other cells, the association between the cell and the information domain is defined according to the same rules, and for the cell where the terminal is located when receiving the DCI, it is defined to be associated with the first information domain.
据此,终端可以确定第1个信息域的值所指示的调度信息为终端接收所述DCI时所在小区的调度信息,从第2个信息域开始到第n个信息域为止,第i个信息域的值所指示的调度信息为第i-1个其他小区的调度信息,从而在通过一个DCI对多个小区进行调度的基础上,准确地确定每个小区的调度信息。所述第i个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。Accordingly, the terminal can determine that the scheduling information indicated by the value of the first information field is the scheduling information of the cell where the terminal receives the DCI. Starting from the second information field to the nth information field, the i-th information The scheduling information indicated by the value of the field is the scheduling information of the i-1th other cell, so that on the basis of scheduling multiple cells through one DCI, the scheduling information of each cell can be accurately determined. The number of bits occupied by the i-th information domain and the specific indication method are the same as the single DCI scheduling single cell method.
例如针对第1个小区至第n个小区这n个小区,若所述n个小区包括终端接收所述DCI时所在小区以及n-1个其他小区,以FDRA域采用separate指示方式为例,在DCI中可以设置n个FDRA域,预定义规则可以规定n个FDRA域中第1个FDRA域与终端接收所述DCI时所在小区相关联,在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中,第i个信息域与第i-1个其他小区相关联。若终端接收所述DCI时所在小区的小区id不在k
1至k
n-1之间,那么第i-1个小区的小区id可以为k
i-1。
For example, for n cells from the 1st cell to the nth cell, if the n cells include the cell where the terminal receives the DCI and n-1 other cells, taking the FDRA domain using the separate indication method as an example, in n FDRA domains can be set in DCI, and the predefined rules can stipulate that the first FDRA domain among the n FDRA domains is associated with the cell where the terminal receives the DCI, and the second FDRA domain reaches the nth FDRA domain. Among the n-1 FDRA domains, the i-th information domain is associated with the i-1 other cells. If the cell ID of the cell where the terminal is located when receiving the DCI is not between k 1 and k n-1 , then the cell ID of the i-1th cell may be k i-1 .
在本实施例中,终端可以确定第1个FDRA域指示终端接收所述DCI时所在小区的频域调度信息,在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中,第2个FDRA域指示第1个其他小区(小区k
1)的频域调度信息、…、第i个FDRA 域指示第i-1个其他小区(小区k
i-1)的频域调度信息、…、第n个FDRA域指示第n-1个其他小区(小区k
n-1)的频域调度信息,从而在通过一个DCI对多个小区进行调度的基础上,使得终端可以准确地解读DCI指示的每个小区的频域调度信息。
In this embodiment, the terminal can determine that the first FDRA domain indicates the frequency domain scheduling information of the cell where the terminal is located when receiving the DCI, among the n-1 FDRA domains from the second FDRA domain to the n-th FDRA domain. , the second FDRA field indicates the frequency domain scheduling information of the first other cell (cell k 1 ), ..., the i-th FDRA domain indicates the frequency domain scheduling information of the i-1 other cell (cell k i-1 ) ,..., the nth FDRA domain indicates the frequency domain scheduling information of the n-1th other cell (cell k n-1 ), so that the terminal can accurately interpret it based on scheduling multiple cells through one DCI Frequency domain scheduling information of each cell indicated by DCI.
所述第i个FDRA域所占bits数根据通信协议38.212[2]中的机制确定,即:基于第i个小区的高层配置信令指示的资源分配类型(‘type 0’,‘type 1’,‘dynamic’)确定所述第i个FDRA域所占bits以及FDRA域指示的value与频域资源的对应关系。The number of bits occupied by the i-th FDRA domain is determined according to the mechanism in the communication protocol 38.212 [2], that is: based on the resource allocation type ('type 0', 'type 1' indicated by the high-level configuration signaling of the i-th cell ,'dynamic') determines the corresponding relationship between the bits occupied by the i-th FDRA domain and the value indicated by the FDRA domain and the frequency domain resource.

1至k
n-1之间,那么第i-1个小区的小区id可以为k
i-1。
For example, for n cells from the 1st cell to the nth cell, if the n cells include the cell where the terminal receives the DCI and n-1 other cells, the ZP CSI-RS trigger field uses the separate indication method. For example, n ZP CSI-RS trigger domains can be set in DCI, and the predefined rules can stipulate that the first ZP CSI-RS trigger domain among the n ZP CSI-RS trigger domains is related to the cell where the terminal receives the DCI. In the n-1 FDRA fields from the 2nd ZP CSI-RS trigger field to the n-th ZP CSI-RS trigger field, the i-th information field is associated with the i-1th other cell. If the cell ID of the cell where the terminal is located when receiving the DCI is not between k 1 and k n-1 , then the cell ID of the i-1th cell may be k i-1 .

The number of bits occupied by the i-th BWP domain is determined according to the mechanism in communication protocol 38.212 [2], that is, the number of bits occupied by the i-th BWP domain is determined based on the high-level configuration BWP number n BWP of the i-th cell, and RRC .
其中,关于多个信息域的顺序,可以按照多个信息域占用比特bit的顺序从前到后以此确定,也即第i-1个信息域占用的比特在第i个信息域占用的比特之前。而关于多个小区的顺序,在后续实施例中说明如何确定。Among them, the order of multiple information fields can be determined from front to back according to the order of the bits occupied by the multiple information fields, that is, the bits occupied by the i-1th information field are before the bits occupied by the i-th information field. . Regarding the order of multiple cells, how to determine it will be described in subsequent embodiments.
以下通过几个实施例示例性说明,预定义规则按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系,如何确定多个小区的顺序。The following exemplifies how to determine the order of multiple cells by using several embodiments to illustrate how predefined rules stipulate the association between the cell where the terminal is located when receiving the DCI and other cells and the information domain according to different rules.
在一个实施例中,所述预定义规则规定第i-1个其他小区的标识小于第i个其他小区的标识;或者,所述预定义规则规定第i-1个其他小区的标识大于第i个其他小区的标识。In one embodiment, the predefined rule stipulates that the identity of the ith other cell is smaller than the identity of the ith other cell; or, the predefined rule stipulates that the identity of the ith other cell is greater than the ith other cell. identification of other communities.
关于小区的标识(例如Cell ID),终端可以根据网络设备发送的RRC信令确定,例如根据RRC信令中的ServcellIndex和/或SCellIndex等IE确定;而在小区的标识对应PCI,那么可以根据RRC信令中的信息元素PhysCellId确定;当然,也可以根据其他方式确定,例如可以为预定义规则规定的。Regarding the identity of the cell (such as Cell ID), the terminal can determine it based on the RRC signaling sent by the network device, for example, based on the ServcellIndex and/or SCellIndex and other IEs in the RRC signaling; and the identity of the cell corresponds to the PCI, then it can be determined based on the RRC The information element PhysCellId in signaling is determined; of course, it can also be determined in other ways, for example, it can be specified by predefined rules.
预定义规则可以根据小区的标识对小区进行排序,例如可以按照标识由小到大进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的标识小于第i个其他小区的标识,若终端接收所述DCI时所在小区的小区id不在k
1至k
n-1之间,k
i-1小于k
i;或者可以按照标识由大到小进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的标识大于第i个其他小区的标识,若终端接收所述DCI时所在小区的小区id不在k
1至k
n-1之间,k
i-1大于k
i。
The predefined rules can sort the cells according to their identities. For example, they can sort the identities from small to large. Then the cell where the terminal is located when receiving the DCI is the 1st cell, and the i-1th other cell has an identity smaller than the 1st cell. Identities of i other cells, if the cell ID of the cell where the terminal is located when receiving the DCI is not between k 1 and k n-1 , k i-1 is smaller than k i ; or the identities can be sorted from large to small, then The cell where the terminal is located when receiving the DCI is the 1st cell, and the identity of the i-1th other cell is greater than the identity of the i-th other cell. If the cell ID of the cell where the terminal is receiving the DCI is not between k 1 and k n -1 , k i-1 is greater than k i .
例如以4个小区为例,分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4,其中小区#3为终端接收所述DCI时所在小区。若按照标识由小到大排序,那么第1个小区为小区#3,对于除了小区#3以外的其他小区,k
i-1小于k
i,第2个小区为小区#1,第3个小区为小区#2,第4个小区为小区#4;若按照标识由大到小排序,那么第1个小区为小区#3,对于除了小区#3以外的其他小区,k
i-1大于k
i,第2个小区为小区#4,第3个小区为小区#2,第4个小区为小区#1。
For example, taking four cells as an example, they are cell #1 with the identity of 1, cell # 2 with the identity of 2, cell # 3 with the identity of 3, and cell #4 with the identity of 4, where cell # 3 is the receiving location for the terminal. The community where DCI is described. If sorted from small to large by identifier, then the first cell is cell # 3. For other cells except cell # 3, k i-1 is smaller than k i . The second cell is cell #1, and the third cell is cell # 3. is cell # 2, and the fourth cell is cell #4; if sorted according to the identifier from large to small, then the first cell is cell # 3. For other cells except cell # 3, k i-1 is greater than k i , the second cell is cell #4, the third cell is cell # 2, and the fourth cell is cell #1.
据此,可以根据小区的标识准确地确定小区的排序,进而可以第i个信息域调度的第i个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined based on the identities of the cells, and further, which cell is the i-th cell scheduled in the i-th information domain.
在一个实施例中,所述预定义规则规定第i-1个其他小区的中心频率小于第i个其他小区的中心频率;或者,所述预定义规则规定第i-1个其他小区的中心频率大于第i个其他小区的中心频率。In one embodiment, the predefined rule stipulates that the center frequency of the ith other cell is smaller than the center frequency of the ith other cell; or, the predefined rule stipulates that the center frequency of the ith other cell is smaller than the center frequency of the i-1 other cell. Greater than the center frequency of the i-th other cell.
关于小区的中心频率,终端可以根据网络设备发送的信息确定,例如根据网络设备发送的同步信号块SSB确定;当然,也可以根据其他方式确定,例如可以为预定义规则规定的。Regarding the center frequency of the cell, the terminal can determine it based on the information sent by the network device, for example, based on the synchronization signal block SSB sent by the network device; of course, it can also be determined based on other methods, such as predefined rules.
预定义规则可以根据小区的中心频率对小区进行排序,例如可以按照中心频率由小到大进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的中心频率小于第i个其他小区的中心频率;或者可以按照中心频率由大到小进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的中心频率大于第i个其他小区的中心频率。The predefined rules can sort the cells according to the center frequency of the cell. For example, the cells can be sorted according to the center frequency from small to large. Then the cell where the terminal is located when receiving the DCI is the 1st cell, and the center of the i-1th other cell. The frequency is smaller than the center frequency of the i-th other cell; or the center frequency can be sorted from large to small, then the cell where the terminal receives the DCI is the first cell, and the center frequency of the i-1 other cell is greater than the The center frequency of i other cells.
例如以4个小区为例,小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4,其中,f1>f2>f3>f4,小区#3为终端接收所述DCI时所在小区。若按照中心频率由小到大排序,那么第1个小区为小区#3,第2个小区为小区#4,第3个小区为小区#2,第4个小区为小区#1;若按照中心频率由大到小排序,那么第1个小区为小区#3,第2个小区为小区#1,第3个小区为小区#2,第4个小区为小区#4。For example, taking four cells as an example, the center frequency of cell #1 is f1, the center frequency of cell # 2 is f2, the center frequency of cell # 3 is f3, and the center frequency of cell #4 is f4, where f1>f2> f3>f4, cell # 3 is the cell where the terminal is located when receiving the DCI. If sorted according to the center frequency from small to large, then the first cell is cell # 3, the second cell is cell #4, the third cell is cell # 2, and the fourth cell is cell #1; if according to the center frequency The frequencies are sorted from large to small, then the first cell is cell # 3, the second cell is cell #1, the third cell is cell # 2, and the fourth cell is cell #4.
据此,可以根据小区的中心频率准确地确定小区的排序,进而可以第i个信息域调度的第i个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined according to the center frequency of the cells, and further, which cell is the i-th cell scheduled in the i-th information domain.
在一个实施例中,所述预定义规则规定第i-1个其他小区的中心频率对应的绝对无线频率信道编号ARFCN小于第i个其他小区的中心频率对应的ARFCN;或者, 所述预定义规则规定第i-1个其他小区的中心频率对应的ARFCN大于第i个其他小区的中心频率对应的ARFCN。In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the i-1th other cell is smaller than the ARFCN corresponding to the center frequency of the i-th other cell; or, the predefined rule It is specified that the ARFCN corresponding to the center frequency of the i-1th other cell is greater than the ARFCN corresponding to the center frequency of the i-th other cell.
关于小区的ARFCN,终端可以根据小区的中心频率确定,也可以通过其他方式确定。Regarding the ARFCN of the cell, the terminal can determine it according to the center frequency of the cell or by other methods.
预定义规则可以根据小区的ARFCN对小区进行排序,例如可以按照ARFCN由小到大进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的ARFCN小于第i个其他小区的ARFCN;或者可以按照ARFCN由大到小进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的ARFCN大于第i个其他小区的ARFCN。The predefined rules can sort the cells according to their ARFCN. For example, they can sort according to the ARFCN from small to large. Then the cell where the terminal is located when receiving the DCI is the 1st cell, and the ARFCN of the i-1th other cell is smaller than the ith. The ARFCN of i other cells; or the ARFCN can be sorted from large to small, then the cell where the terminal receives the DCI is the 1st cell, and the ARFCN of the i-1 other cell is greater than the ARFCN of the i other cell. .
例如以4个小区为例,小区#1的ARFCN为ARFCN#1、小区#2的ARFCN为ARFCN#2、小区#3的ARFCN为ARFCN#3、小区#4的ARFCN为ARFCN#4,其中,ARFCN#1>ARFCN#2>ARFCN#3>ARFCN#4,小区#3为终端接收所述DCI时所在小区。若按照ARFCN由小到大排序,那么第1个小区为小区#3,第2个小区为小区#4,第3个小区为小区#2,第4个小区为小区#1;若按照ARFCN由大到小排序,那么第1个小区为小区#3,第2个小区为小区#1,第3个小区为小区#2,第4个小区为小区#4。For example, taking 4 cells as an example, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell # 2 is ARFCN# 2, the ARFCN of cell # 3 is ARFCN# 3, and the ARFCN of cell #4 is ARFCN#4, where, ARFCN#1>ARFCN# 2>ARFCN# 3>ARFCN#4, cell # 3 is the cell where the terminal is located when receiving the DCI. If sorted according to ARFCN from small to large, then the first cell is cell # 3, the second cell is cell #4, the third cell is cell # 2, and the fourth cell is cell #1; if according to ARFCN by Sorting from large to small, then the first cell is cell # 3, the second cell is cell #1, the third cell is cell # 2, and the fourth cell is cell #4.
据此,可以根据小区的ARFCN准确地确定小区的排序,进而可以第i个信息域调度的第i个小区具体为哪个小区。Accordingly, the ordering of cells can be accurately determined according to the ARFCN of the cells, and further, which cell is the i-th cell scheduled in the i-th information domain.
图2是根据本公开的实施例示出的一种下行控制信息发送方法的示意流程图。本实施例所示的下行控制信息发送方法可以适用于网络设备,所述网络设备可以与终端通信,所述网络设备包括但不限于4G基站、5G基站、6G基站等通信***中的基站,所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。Figure 2 is a schematic flow chart of a method for sending downlink control information according to an embodiment of the present disclosure. The downlink control information sending method shown in this embodiment can be applied to network equipment, which can communicate with terminals. The network equipment includes but is not limited to base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminals include but are not limited to mobile phones, tablets, wearable devices, sensors, Internet of Things devices and other communication devices.
如图2所示,所述下行控制信息发送方法可以包括以下步骤:As shown in Figure 2, the downlink control information sending method may include the following steps:
在步骤S201中,确定用于调度多个小区的下行控制信息DCI中相同类型的多个信息域与多个小区之间的关联关系;In step S201, determine the association between multiple information domains of the same type in the downlink control information DCI used for scheduling multiple cells and multiple cells;
在步骤S202中,根据所述关联关系生成DCI;In step S202, generate DCI according to the association relationship;
在步骤S203中,向终端发送生成的DCI。In step S203, the generated DCI is sent to the terminal.
在一个实施例中,DCI中可以包括多种类型的信息域,例如FDRA域、ZP CSI-RS trigger域、部分带宽指示域等。In one embodiment, DCI may include multiple types of information fields, such as FDRA fields, ZP CSI-RS trigger fields, partial bandwidth indication fields, etc.
在现有的DCI中,同一个类型的信息域,一般只包含一个,根据这个类型的信息域可以对一个小区进行调度,例如FDRA信息域可以调度小区的频域资源。In the existing DCI, the same type of information domain generally contains only one. A cell can be scheduled according to this type of information domain. For example, the FDRA information domain can schedule the frequency domain resources of the cell.
本实施例可以应用在一个DCI调度多个小区的场景中。在本实施例中,网络设备可以确定相同类型的多个信息域与多个小区之间的关联关系,进而根据所述关联关系设置每个小区的信息域,从而生成DCI,并将DCI发送至终端,实现对多个小区的调度。相同类型的信息域对应指示的信息类型相同,例如,指示不同小区的频域资源FDRA,例如,指示不同小区配置的BWP索引,具体可见下述描述。This embodiment can be applied in a scenario where one DCI schedules multiple cells. In this embodiment, the network device can determine the association between multiple information domains of the same type and multiple cells, and then set the information domain of each cell according to the association, thereby generating DCI and sending the DCI to The terminal implements scheduling of multiple cells. Information fields of the same type correspond to indicating the same type of information, for example, indicating frequency domain resources FDRA of different cells, for example, indicating BWP indexes configured in different cells. For details, see the following description.
这种指示方式可以称作分别separate指示,例如一个DCI中特定类型信息域可以包括多个信息域。可以在调度单个小区的一个DCI中信息域的基础上,根据小区的数目对特定类型信息域做对应比特bits的扩展,从而得到多个相同类型的信息域,其中不同的信息域指示不同小区的消息。一个DCI中多个相同类型信息域所占的bits数等于每个小区对应的上述信息域所占bits数的和。每个小区对应的上述信息域所占bits数与现有机制中,调度一个小区的DCI的相同类型信息域所占bits数相同。This indication method can be called separate indication. For example, a specific type of information field in a DCI can include multiple information fields. On the basis of scheduling the information field in a DCI of a single cell, the specific type of information field can be extended with corresponding bits according to the number of cells, thereby obtaining multiple information fields of the same type, where different information fields indicate the information of different cells. information. The number of bits occupied by multiple information fields of the same type in a DCI is equal to the sum of the number of bits occupied by the above information fields corresponding to each cell. The number of bits occupied by the above information field corresponding to each cell is the same as the number of bits occupied by the same type of information field used to schedule DCI of a cell in the existing mechanism.
如图1B所示,以BWP指示域为例,在用于调度3个小区(小区id号分别为0、1和2)的一个DCI中,包括3个BWP指示域,3个BWP指示域占用5bits,例如值为01100。As shown in Figure 1B, taking the BWP indication domain as an example, a DCI used to schedule 3 cells (cell ID numbers are 0, 1 and 2 respectively) includes 3 BWP indication domains, and the 3 BWP indication domains occupy 5bits, for example the value is 01100.
其中,第1个和第2个比特(01)对应小区0,因此可以根据第1个和第2个比特(01)确定小区0的BWP id=2;第3个和第4个比特(10)对应小区1,因此可以根据第3个和第4个比特(10)确定小区1的BWP id=3;第5个比特(0)对应小区0,因此可以根据第5个比特(0)确定小区2的BWP id=1。Among them, the 1st and 2nd bits (01) correspond to cell 0, so the BWP id=2 of cell 0 can be determined based on the 1st and 2nd bits (01); the 3rd and 4th bits (10 ) corresponds to cell 1, so the BWP id=3 of cell 1 can be determined based on the 3rd and 4th bits (10); the 5th bit (0) corresponds to cell 0, so it can be determined based on the 5th bit (0) BWP id of cell 2=1.
所述3个BWP指示域占用的bits数等于所述3个小区BWP域所占bits数的和。对于特定小区对应的BWP域所占bits数基于现有机制确定,即,基于特定小区的高层配置BWP数量n
BWP,RRC确定特定小区对应的BWP域所占bits数。
The number of bits occupied by the three BWP indication domains is equal to the sum of the number of bits occupied by the three cell BWP domains. The number of bits occupied by the BWP domain corresponding to a specific cell is determined based on the existing mechanism, that is, the number of bits occupied by the BWP domain corresponding to the specific cell is determined based on the high-level configuration of the specific cell n BWP, and RRC determines the number of bits occupied by the BWP domain corresponding to the specific cell.
对于调度多个小区的DCI中特定类型的信息域,若特定类型的信息域采用separate方式,特定类型的信息域可以包括多个信息域,多个信息域占用比特bits对应索引为:
其中,索引1对应DCI特定类型信息域中的第一个bit,索引
为第1个信息域对应对应bits,用于指示小区k
0的调度信息, 索引
为第i个信息域对应bits,用于指示小区k
i的调度信息,索引
为第n个信息域对应bits,用于指示小区k
n的调度信息,n等于小区数,其中k
j为小区id号。例如预定义规则可以规定n个信息域中第j个信息域与n个小区中的第j个小区相关联,其中,第j个小区的小区id可以为k
j。
For a specific type of information domain in DCI that schedules multiple cells, if the specific type of information domain adopts the separate mode, the specific type of information domain can include multiple information domains, and the corresponding index of the bits occupied by multiple information domains is: Among them, index 1 corresponds to the first bit in the DCI specific type information field, index It is the corresponding bits corresponding to the first information field, used to indicate the scheduling information of cell k 0 , index are the bits corresponding to the i-th information field, used to indicate the scheduling information of cell k i , index are the bits corresponding to the nth information field, used to indicate the scheduling information of cell k n , where n is equal to the number of cells, where k j is the cell ID number. For example, the predefined rule may stipulate that the j-th information domain among n information fields is associated with the j-th cell among n cells, where the cell ID of the j-th cell may be k j .
相对应地,终端可以确定相同类型的多个信息域与多个小区之间的关联关系,进而根据关联关系确定每个信息域对应的小区,从而可以根据小区对应的信息域的值,确定小区的调度信息,最后可以通过调度信息对对应的小区进行调度。从而在通过一个DCI对多个小区进行调度的基础上,准确地确定每个小区的调度信息。Correspondingly, the terminal can determine the association between multiple information domains of the same type and multiple cells, and then determine the cell corresponding to each information domain based on the association, so that the cell can be determined based on the value of the information domain corresponding to the cell. Scheduling information, and finally the corresponding cell can be scheduled through the scheduling information. Thus, on the basis of scheduling multiple cells through one DCI, the scheduling information of each cell can be accurately determined.
由于DCI中可以设置有多种类型的信息域,对于其中任意一种或几种类型,都可以采用separate的方式设置多个信息域来实现对多个小区的调度,具体针对哪种或哪几种类型设置多个信息域,可以根据预定义规则确定或根据信令指示确定。例如对于FDRA域和BWP指示域,信令指示FDRA域基于separate的方式指示,那么在DCI中可以针对多个小区,设置多个FDRA域;例如预定义规则规定针对FDAR域和BWP域都基于separate的方式指示,那么在DCI中可以针对多个小区,设置多个FDRA域以及多个BWP指示域。Since multiple types of information domains can be set in DCI, for any one or several types, multiple information domains can be set up in a separate manner to achieve scheduling of multiple cells, specifically for which one or several types. Multiple information fields are set for each type, which can be determined according to predefined rules or according to signaling instructions. For example, for the FDRA domain and the BWP indication domain, if the signaling indicates that the FDRA domain is based on separate indication, multiple FDRA domains can be set for multiple cells in the DCI; for example, the predefined rules stipulate that both the FDAR domain and the BWP domain are based on separate mode indication, then multiple FDRA domains and multiple BWP indication domains can be set for multiple cells in DCI.
需要说明的是,关于DCI所调度的多个小区的数量和/或多个小区对应的小区号,也即多个小区,终端可以根据DCI中的CIF来确定,也可以是与网络设备预先约定的,还可以是根据预定义规则(例如协议约定)确定的,本公开并不限制。It should be noted that the terminal can determine the number of multiple cells scheduled by DCI and/or the cell numbers corresponding to the multiple cells, that is, the multiple cells, based on the CIF in the DCI, or it can be pre-agreed with the network equipment. , or may be determined based on predefined rules (such as agreement), which is not limited by this disclosure.
在一个实施例中,所述关联关系中的多个小区为小区集合的多个小区,其中,所述小区集合包括以下至少之一:In one embodiment, the multiple cells in the association relationship are multiple cells in a cell set, wherein the cell set includes at least one of the following:
所述DCI所能调度的小区构成的小区集合;A set of cells composed of cells that can be scheduled by the DCI;
具有相同配置参数的小区构成的小区集合。A set of cells composed of cells with the same configuration parameters.
在这种情况下,用于调度多个小区的DCI中相同类型的信息域的数量,等于小区集合中小区的数量,从而对于某个类型的信息域而言,可以一一对应地实现对小区的指示。In this case, the number of information fields of the same type in the DCI used to schedule multiple cells is equal to the number of cells in the cell set. Therefore, for a certain type of information field, one-to-one correspondence can be achieved for cells. instructions.
在一个实施例中,所述关系中的多个小区可以属于一个小区集合,小区集合可以是用于调度多个小区的DCI所能调度的小区构成的小区集合。In one embodiment, multiple cells in the relationship may belong to a cell set, and the cell set may be a cell set composed of cells that can be scheduled by the DCI used to schedule multiple cells.
例如用于调度多个小区的DCI所能调度的小区为4个小区Cell#1、Cell#2、 Cell#3、Cell#4,那么小区集合可以是{Cell#1、Cell#2、Cell#3、Cell#4}。For example, the DCI used to schedule multiple cells can schedule four cells: Cell#1, Cell# 2, Cell# 3, and Cell#4. Then the cell set can be {Cell#1, Cell# 2, Cell# 3. Cell#4}.
例如用于调度多个小区的DCI中相同类型的多个信息域的数量与所能调度的小区的数量相同,但是用于调度多个小区的DCI实际调度的小区的数量小于等于所能调度的小区的数量。那么对于相同类型的多个信息域中对应未调度小区的信息域,终端可以忽略;或者,对于相同类型的多个信息域中对应未调度小区的信息域的值,可以设置为预定义的值(例如,零填充),以便终端基于该预定义的值可以确定该信息域不用于指示调度信息。For example, the number of multiple information domains of the same type in the DCI used to schedule multiple cells is the same as the number of cells that can be scheduled, but the number of cells actually scheduled by the DCI used to schedule multiple cells is less than or equal to the number of cells that can be scheduled. The number of plots. Then, the terminal can ignore the information field corresponding to the unscheduled cell among the multiple information fields of the same type; or, the value of the information field corresponding to the unscheduled cell among the multiple information fields of the same type can be set to a predefined value. (for example, zero padding), so that the terminal can determine that the information field is not used to indicate scheduling information based on the predefined value.
多个信息域的数量与所能调度的小区的数量相同,均为4,用于调度多个小区的DCI实际调度的小区的数量为3,例如调度上述Cell#1、Cell#3、Cell#4,那么终端可以忽略4个信息域中与Cell#2对应的信息域filed#2,或者,网络设备可以将filed#2的值设置为预定义的值,终端根据filed#2的值可以确定filed#2不用于指示调度信息。The number of multiple information fields is the same as the number of cells that can be scheduled, which is 4. The number of cells actually scheduled by the DCI used to schedule multiple cells is 3. For example, the above-mentioned Cell#1, Cell# 3, and Cell# are scheduled. 4, then the terminal can ignore the information field filed#2 corresponding to Cell# 2 among the 4 information fields, or the network device can set the value of filed#2 to a predefined value, and the terminal can determine it based on the value of filed#2 filed#2 is not used to indicate scheduling information.
在一个实施例中,所述关系中的多个小区可以属于一个小区集合,小区集合可以具有相同配置参数的小区构成的小区集合。其中,所述配置参数包括但不限于集合标识、小区标识、序号、载波指示域(Carrier Indicator Field,CIF);In one embodiment, multiple cells in the relationship may belong to a cell set, and the cell set may be a cell set composed of cells with the same configuration parameters. Wherein, the configuration parameters include but are not limited to aggregation identification, cell identification, sequence number, and carrier indicator field (Carrier Indicator Field, CIF);
例如以4个小区Cell#1、Cell#2、Cell#3、Cell#4,配置参数包括CIF为例,可以确定为这4个小区中每个小区配置的CIF(例如根据无线资源控制RRC信令确定)。例如为Cell#1配置的CIF为01,为Cell#2配置的CIF为01,为Cell#3配置的CIF为02,为Cell#4配置的CIF为02,那么可以确定Cell#1和Cell#2具有相同的CIF,Cell#3和Cell#4具有相同的CIF,从而将Cell#1和Cell#2划分为一个用于调度多个小区的下行控制信息对应的小区集合{Cell#1、Cell#2},将Cell#3和Cell#4划分为另一个用于调度多个小区的下行控制信息对应的小区集合{Cell#3、Cell#4}。For example, taking four cells, Cell#1, Cell# 2, Cell# 3, and Cell#4, and the configuration parameters include CIF, the CIF configured for each of the four cells can be determined (for example, according to the radio resource control RRC signal Order to confirm). For example, the CIF configured for Cell#1 is 01, the CIF configured for Cell# 2 is 01, the CIF configured for Cell# 3 is 02, and the CIF configured for Cell#4 is 02, then you can determine Cell#1 and Cell# 2 has the same CIF, Cell# 3 and Cell#4 have the same CIF, thus dividing Cell#1 and Cell# 2 into a cell set corresponding to the downlink control information for scheduling multiple cells {Cell#1, Cell #2}, divide Cell# 3 and Cell#4 into another cell set {Cell# 3, Cell#4} that is used to schedule downlink control information of multiple cells.
在一个实施例中,所述方法还包括:In one embodiment, the method further includes:
向所述终端发送信令指示所述小区集合,或者根据预定义规则确定所述小区集合。Send signaling to the terminal to indicate the cell set, or determine the cell set according to predefined rules.
所述小区集合可以是网络设备确定后,通过信令指示给终端的,其中,所述信令包括但不限于RRC信令、DCI、MAC CE等。所述小区集合也可以是基于预定义规则确定的,例如预定义规则为具有相同配置参数的小区属于同一小区集合,那么可以确定小区的配置参数,并将具有相同配置参数的小区确定为属于同一小区集合。The cell set may be determined by the network device and then indicated to the terminal through signaling, where the signaling includes but is not limited to RRC signaling, DCI, MAC CE, etc. The cell set can also be determined based on predefined rules. For example, the predefined rule is that cells with the same configuration parameters belong to the same cell set. Then the configuration parameters of the cells can be determined, and the cells with the same configuration parameters can be determined as belonging to the same cell set. Community gathering.
在一个实施例中,所述小区集合包含的小区包括以下至少之一:In one embodiment, the cells included in the cell set include at least one of the following:
调度小区;dispatching area;
被调度小区。The scheduled cell.
例如,小区集合可以包含被调度小区,也即用于调度多个小区的DCI调度的小区;例如,小区集合可以包含调度小区,也即终端接收用于调度多个小区的DCI时所在的小区;例如,小区集合可以包括调度小区和被调度小区。For example, the cell set may include scheduled cells, that is, cells used for scheduling DCI scheduling of multiple cells; for example, the cell set may include scheduling cells, that is, the cells where the terminal is located when receiving DCI used for scheduling multiple cells; For example, a cell set may include a scheduling cell and a scheduled cell.
需要说明的是,调度小区和被调度小区,都可以属于用于调度多个小区的DCI所能调度的小区。It should be noted that both the scheduling cell and the scheduled cell may belong to cells that can be scheduled by the DCI used to schedule multiple cells.
在一个实施例中,所述关联关系中多个信息域的数量,等于所述DCI所能调度的最大小区数量。In one embodiment, the number of multiple information fields in the association relationship is equal to the maximum number of cells that can be scheduled by the DCI.
在一个实施例中,用于调度多个小区的DCI,每次所调度的多个小区可以是不同的,终端可以根据网络设备发送的指示信息,或者根据预定义规则(例如协议约定)确定用于调度多个小区的DCI每次所调度的多个小区。In one embodiment, the DCI used to schedule multiple cells may be different each time. The terminal may determine the user according to the instruction information sent by the network device or according to predefined rules (such as protocol agreement). The DCI for scheduling multiple cells schedules multiple cells at a time.
以根据网络设备发送的指示信息确定用于调度多个小区的DCI每次所调度的多个小区为例,网络设备可以向终端发送指示信息与调度多个小区的DCI每次所调度的多个小区之间的对应关系(例如可以为表格形式,可以携带在RRC信令中发送给终端)。终端在接收到用于调度多个小区的DCI时,可以在对应关系中确定网络设备发送的指示信息(例如携带在所述DCI中,或者携带在其他信令中)指示所述DCI调度的多个小区。终端还可以根据对应关系确定DCI所能调度的最大小区数量,也即对应关系中,指示信息所指示的DCI调度最多小区时小区的数量。Taking the example of determining the multiple cells that are scheduled each time by the DCI for scheduling multiple cells based on the instruction information sent by the network device, the network device can send the instruction information to the terminal along with the multiple cells that are scheduled by the DCI that schedules multiple cells each time. Correspondence between cells (for example, it can be in the form of a table and can be carried in RRC signaling and sent to the terminal). When receiving DCI for scheduling multiple cells, the terminal may determine in the corresponding relationship that the instruction information sent by the network device (for example, carried in the DCI or carried in other signaling) indicates that the DCI schedules multiple cells. A community. The terminal can also determine the maximum number of cells that can be scheduled by DCI according to the corresponding relationship, that is, in the corresponding relationship, the number of cells when the DCI indicated by the indication information schedules the most cells.
例如对应关系包括:指示信息为1,DCI调度的多个小区为Cell#1、Cell#2;指示信息为2,DCI调度的多个小区为Cell#3、Cell#4;指示信息为3,DCI调度的多个小区为Cell#1、Cell#2、Cell#4。那么终端可以确定DCI所能调度的最大小区数量为3,进而可以确定DCI中相同类型的多个信息域的数量也为3。For example, the corresponding relationship includes: the indication information is 1, and the multiple cells scheduled by DCI are Cell#1 and Cell# 2; the indication information is 2, and the multiple cells scheduled by DCI are Cell# 3 and Cell#4; the indication information is 3, The multiple cells scheduled by DCI are Cell#1, Cell# 2, and Cell#4. Then the terminal can determine that the maximum number of cells that can be scheduled by DCI is 3, and further can determine that the number of multiple information domains of the same type in DCI is also 3.
后续终端在接收到用于调度多个小区的DCI时,可以先确定DCI实际调度小区的数量。若DCI实际调度小区的数量等于相同类型的多个信息域的数量,那么可以根据DCI实际调度小区的标识从小到大(或从大到小)与多个信息域相对应,确定每个信息域所指示的小区。When a subsequent terminal receives DCI for scheduling multiple cells, it can first determine the number of cells actually scheduled by the DCI. If the number of cells actually scheduled by DCI is equal to the number of multiple information domains of the same type, then each information domain can be determined based on the identification of the cells actually scheduled by DCI corresponding to the multiple information domains from small to large (or from large to small). the indicated neighborhood.
例如DCI实际调度的小区为Cell#1、Cell#2、Cell#4,那么可以确定第一个信息域用于针对Cell#1进行指示,第二个信息域用于针对Cell#2进行指示,第三个信息 域用于针对Cell#4进行指示。For example, the cells actually scheduled by DCI are Cell#1, Cell# 2, and Cell#4. Then it can be determined that the first information field is used to indicate Cell#1, and the second information field is used to indicate Cell# 2. The third information field is used to indicate Cell#4.
若DCI实际调度小区的数量小于相同类型的多个信息域的数量,那么可以根据DCI实际调度小区的标识从小到大(或从大到小)与多个信息域相对应,确定每个信息域所指示的小区,并针对未对应的信息域设置为预定义的值,以便终端基于该预定义的值可以确定该信息域不用于针对小区进行指示;或者,针对未对应的信息域可以设置为预留位(reserved),以便终端基于预留位可以确定该信息域不用于针对小区进行指示。If the number of cells actually scheduled by DCI is less than the number of multiple information domains of the same type, then each information domain can be determined based on the identification of the cells actually scheduled by DCI corresponding to the multiple information domains from small to large (or from large to small). The indicated cell, and set to a predefined value for the uncorresponding information field, so that the terminal can determine based on the predefined value that the information field is not used to indicate the cell; or, for the uncorresponding information field, it can be set to Reserved bits (reserved), so that the terminal can determine based on the reserved bits that this information field is not used to indicate the cell.
例如根据DCI实际调度小区的标识从小到大与多个信息域相对应,DCI实际调度的小区为Cell#1、Cell#2。若从多个信息域的第一个信息域开始对应,那么可以确定最后一个信息域未对应,那么可以确定第一个信息域用于针对Cell#1进行指示,第二个信息域用于针对Cell#2进行指示,第三个信息域为预定义的值;若从多个信息域的最后一个信息域开始对应,那么可以确定第一个信息域未对应,那么可以确定第三个信息域用于针对Cell#1进行指示,第二个信息域用于针对Cell#2进行指示,第一个信息域为预定义的值。For example, the identifiers of cells actually scheduled by DCI correspond to multiple information fields from small to large, and the cells actually scheduled by DCI are Cell#1 and Cell# 2. If the correspondence starts from the first information field of multiple information fields, then it can be determined that the last information field is not corresponding, then it can be determined that the first information field is used to indicate Cell#1, and the second information field is used to indicate Cell#1. Cell# 2 indicates that the third information field is a predefined value; if the correspondence starts from the last information field of multiple information fields, then it can be determined that the first information field is not corresponding, then the third information field can be determined It is used to indicate Cell#1, the second information field is used to indicate Cell# 2, and the first information field is a predefined value.
例如根据DCI实际调度小区的标识从大到小与多个信息域相对应,DCI实际调度的小区为Cell#1、Cell#2。若从多个信息域的第一个信息域开始对应,那么可以确定最后一个信息域未对应,那么可以确定第一个信息域用于针对Cell#2进行指示,第二个信息域用于针对Cell#1进行指示,第三个信息域为预定义的值;若从多个信息域的最后一个信息域开始对应,那么可以确定第一个信息域未对应,那么可以确定第三个信息域用于针对Cell#2进行指示,第二个信息域用于针对Cell#1进行指示,第一个信息域为预定义的值。For example, the identifiers of the cells actually scheduled by the DCI correspond to multiple information fields from large to small, and the cells actually scheduled by the DCI are Cell#1 and Cell# 2. If the correspondence starts from the first information field of multiple information fields, then it can be determined that the last information field is not corresponding, then it can be determined that the first information field is used to indicate Cell # 2, and the second information field is used to indicate Cell # 2. Cell#1 indicates that the third information field is a predefined value; if the correspondence starts from the last information field of multiple information fields, then it can be determined that the first information field is not corresponding, then the third information field can be determined It is used to indicate Cell# 2, the second information field is used to indicate Cell#1, and the first information field is a predefined value.
在一个实施例中,所述确定用于调度多个小区的下行控制信息DCI中相同类型的多个信息域与多个小区之间的关联关系包括:根据预定义规则确定所述关联关系。In one embodiment, determining the association relationship between multiple information domains of the same type in the downlink control information DCI used for scheduling multiple cells and multiple cells includes: determining the association relationship according to predefined rules.

DCI中的相同类型的多个信息域与多个小区之间的关联关系可以是预定义规则规定的,例如协议约定的;也可以由网络设备根据需要确定,然后指示给终端,其中,网络设备指示所述关联关系的方式包括但不限于通过RRC信令进行指示、通过 DCI进行指示、通过MAC CE进行指示。The association between multiple information domains of the same type in DCI and multiple cells can be stipulated by predefined rules, such as agreed in a protocol; it can also be determined by the network device as needed and then indicated to the terminal, where the network device Methods for indicating the association relationship include but are not limited to indicating through RRC signaling, indicating through DCI, and indicating through MAC CE.
以下实施例主要针对预定义规则规定所述关联关系的情况进行示例性说明。The following embodiments mainly illustrate the case where the association relationship is stipulated by predefined rules.
在一个实施例中,所述多个信息域包括n个信息域,所述多个小区包括n个小区;所述预定义规则规定所述n个信息域中第j个信息域与所述n个小区中的第j个小区相关联,其中,1≤j≤n。In one embodiment, the plurality of information domains includes n information domains, and the plurality of cells includes n cells; the predefined rule stipulates that the jth information domain among the n information domains is the same as the n information domain. The j-th cell among the cells is associated, where 1≤j≤n.
多个小区可以包括终端接收所述DCI时所在小区以及其他小区(中终端接收所述DCI时所在小区以外的小区),也可以不包括终端接收所述DCI时所在小区,仅包括其他小区。本实施中预定义规则在规定小区与信息域之间的关联关系时,可以不区分终端接收所述DCI时所在小区以及其他小区,按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。The multiple cells may include the cell where the terminal receives the DCI and other cells (cells other than the cell where the terminal receives the DCI), or may not include the cell where the terminal receives the DCI and only include other cells. When the predefined rules in this implementation stipulate the association between the cell and the information domain, the cell where the terminal receives the DCI and other cells may not be distinguished. The same rules stipulate that the cell where the terminal receives the DCI and other cells and The relationship between information domains.
以n个小区为例,针对某个类型的信息域,可以设置n个信息域来对这n个小区进行调度,关联关系可以是n个信息域中第j个信息域与n个小区中第j个小区相关联。Taking n cells as an example, for a certain type of information domain, n information domains can be set to schedule the n cells. The association relationship can be the j-th information domain among the n information domains and the j-th information domain among the n cells. j cells are associated.
据此,终端可以确定第j个信息域的值所指示的调度信息为第j个小区的调度信息,从而在通过一个DCI对多个小区进行调度的基础上,准确地确定每个小区的调度信息。所述第j个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。Accordingly, the terminal can determine that the scheduling information indicated by the value of the j-th information field is the scheduling information of the j-th cell, thereby accurately determining the scheduling of each cell based on scheduling multiple cells through one DCI. information.

n)的频域调度信息,从而在通过一个DCI对多个小区进行调度的基础上,使得网络设备可以准确地确定每个小区的频域调度信息,进而生成DCI实现对每个小区的调度。
For example, for n cells from the 1st cell to the nth cell, taking the FDRA domain using the separate indication method as an example, n FDRA domains can be set in the DCI, and the predefined rules can specify the j-th information in the n information domains. The domain is associated with the j-th cell among the n cells, where the cell id of the j-th cell may be k j .

j。在本实施例中,终端可以确定第1个ZP CSI-RS trigger域指示第1个小区(小区k
1)的ZP CSI-RS trigger信息、第2个ZP CSI-RS trigger域指示第2个小区(小区k
2)的ZP CSI-RS trigger信息、…、第j个ZP CSI-RS trigger域指示第j个小区(小区k
j)的ZP CSI-RS trigger信息、…、第n个ZP CSI-RS trigger域指示第n个小区(小区k
n)的ZP CSI-RS trigger信息,从而在通过一个DCI对多个小区进行调度的基础上,使得网络设备可以准确地确定每个小区的ZP CSI-RS trigger信息,进而生成DCI实现对每个小区的调度。
For example, for n cells from the 1st cell to the nth cell, taking the ZP CSI-RS trigger field using the separate indication method as an example, n ZP CSI-RS trigger fields can be set in DCI, and the predefined rules can specify n The j-th information domain among the information domains is associated with the j-th cell among the n cells, where the cell id of the j-th cell may be k j .

RS trigger information, and then generate DCI to implement scheduling for each cell.
所述第j个ZP CSI-RS trigger域所占bits数根据通信协议38.212[2]中的机制确定,即:基于第j个小区的高层配置ZP CSI-RS资源集数量n

n)的BWP信息,从而在通过一个DCI对多个小区进行调度的基础上,使得网络设备可以准确地确定每个小区的BWP信息,进而生成DCI实现对每个小区的调度。
For example, for n cells from the 1st cell to the nth cell, taking the BWP indication field using the separate indication method as an example, n BWP indication fields can be set in DCI, and the predefined rules can specify the jth of the n information fields. The information domain is associated with the j-th cell among the n cells, where the cell id of the j-th cell may be k j . In this embodiment, the terminal can determine that the first BWP indication field indicates the BWP information of the first cell (cell k 1 ), the second BWP indication field indicates the BWP information of the second cell (cell k 2 ), ... , the jth BWP indication field indicates the BWP information of the jth cell (cell k j ),..., the nth BWP indication field indicates the BWP information of the nth cell (cell k n ), so that through one DCI to multiple On the basis of scheduling for each cell, the network equipment can accurately determine the BWP information of each cell, and then generate DCI to implement scheduling for each cell.

Regarding the order of multiple cells, how to determine it will be described in subsequent embodiments.
需要说明的是,对于相同类型的多个信息域,每个信息域对应比特的数量可以相同,也可以不同,还可以为0,具体可以根据通信协议38.212[2]中的机制确定,本 公开在此不作赘述。It should be noted that for multiple information fields of the same type, the number of bits corresponding to each information field can be the same, different, or 0. The details can be determined according to the mechanism in the communication protocol 38.212 [2]. This disclosure No further details will be given here.
以相同类型的4个信息域占用8个比特,若信息域对应比特的数量存在不同,那么可以是第1个信息域对应第1和第2个比特(即比特索引
对应2个比特),第2个信息域对应第3至第5个比特(即比特索引
对应3个比特),第3个信息域对应第6和第7个比特(即比特索引
对应2个比特),第4个信息域对应第8个比特(即比特索引
对应1个比特);若信息域对应比特的数量相同,那么可以是第1个信息域对应第1和第2个比特,第2个信息域对应第3和第4个比特,第3个信息域对应第5和第6个比特,第4个信息域对应第7和第8个比特,也即每个信息域对应2个比特(即比特索引
对应2个比特)。
4 information fields of the same type occupy 8 bits. If the number of corresponding bits in the information fields is different, then the first information field can correspond to the 1st and 2nd bits (i.e. bit index Corresponding to 2 bits), the second information field corresponds to the 3rd to 5th bits (i.e. bit index Corresponding to 3 bits), the third information field corresponds to the 6th and 7th bits (i.e. bit index Corresponding to 2 bits), the 4th information field corresponds to the 8th bit (i.e. bit index Corresponding to 1 bit); if the information fields correspond to the same number of bits, then the first information field can correspond to the 1st and 2nd bits, the second information field corresponds to the 3rd and 4th bits, and the 3rd information field The field corresponds to the 5th and 6th bits, and the 4th information field corresponds to the 7th and 8th bits, that is, each information field corresponds to 2 bits (i.e., bit index corresponds to 2 bits).
以下通过几个实施例示例性说明,预定义规则按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系,以及如何确定多个小区的顺序。The following is an illustrative description through several embodiments. The predefined rules specify the association between the cell where the terminal is located when receiving the DCI and other cells and the information domain according to the same rules, and how to determine the order of multiple cells.
在一个实施例中,所述预定义规则规定第j个小区的标识小于第j+1个小区的标识,也即k
j小于k
j+1;或者,所述预定义规则规定第j个小区的标识大于第j+1个小区的标识,也即k
j大于k
j+1。
In one embodiment, the predefined rule stipulates that the identity of the j-th cell is less than the identity of the j+1-th cell, that is, k j is less than k j+1 ; or, the pre-defined rule stipulates that the j-th cell The identity of is greater than the identity of j+1th cell, that is, k j is greater than k j+1 .
关于小区的标识(例如Cell ID),网络设备可以通过RRC信令进行指示,例如通过RRC信令中的ServcellIndex和/或SCellIndex等IE指示;而若小区的标识对应PCI,那么可以通过RRC信令中的信息元素PhysCellId指示;当然,终端也可以根据其他信令确定。或者,根据其他方式确定,例如可以为预定义规则规定的。Regarding the identity of the cell (such as Cell ID), the network device can indicate it through RRC signaling, for example, through IE indications such as ServcellIndex and/or SCellIndex in RRC signaling; and if the identity of the cell corresponds to PCI, then it can indicate it through RRC signaling. The information element PhysCellId indicates; of course, the terminal can also determine it based on other signaling. Or, determined in other ways, such as may be specified by predefined rules.
预定义规则可以根据小区的标识对小区进行排序,例如可以按照标识由小到大进行排序,那么第j个小区的标识小于第j+1个小区的标识,或者可以按照标识由大到小进行排序,那么第j个小区的标识大于第j+1个小区的标识。The predefined rules can sort the cells according to their identities. For example, they can sort them from small to large, so that the identity of the j-th cell is smaller than the identity of the j+1th cell, or they can sort them from large to small. Sorting, then the identity of the j-th cell is greater than the identity of the j+1-th cell.
例如以4个小区为例,分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4。若按照标识由小到大排序,那么k
j小于k
j+1,可以确定第1个小区为小区#1,第2个小区为小区#2,第3个小区为小区#3,第4个小区为小区#4;若按照标识由大到小排序,那么k
j大于k
j+1,可以确定第1个小区为小区#4,第2个小区为小区#3,第3个小区为小区#2,第4个小区为小区#1。
For example, taking four cells as an example, they are cell #1 with an identifier of 1, cell # 2 with an identifier of 2, cell # 3 with an identifier of 3, and cell #4 with an identifier of 4. If the identifiers are sorted from small to large, then k j is less than k j+1 , it can be determined that the first cell is cell #1, the second cell is cell # 2, the third cell is cell # 3, and the fourth cell is cell # 3. The cell is cell #4; if the identifiers are sorted from large to small, then k j is greater than k j+1 , it can be determined that the first cell is cell #4, the second cell is cell # 3, and the third cell is cell # 2, the 4th cell is cell #1.
据此,可以根据小区的标识准确地确定小区的排序,进而可以第j个信息域调 度的第j个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined according to the identity of the cells, and then the specific cell of the jth cell scheduled in the jth information domain can be determined.
在一个实施例中,所述预定义规则规定第j个小区的中心频率小于第j+1个小区的中心频率;或者,所述预定义规则规定第j个小区的中心频率大于第j+1个小区的中心频率。In one embodiment, the predefined rule stipulates that the center frequency of the jth cell is less than the center frequency of the j+1th cell; or, the predefined rule stipulates that the center frequency of the jth cell is greater than the j+1th cell. The center frequency of a cell.
关于小区的中心频率,网络设备通过向终端发送SSB进行指示;当然,终端也可以根据其他方式确定,例如可以为预定义规则规定的。Regarding the center frequency of the cell, the network device indicates it by sending SSB to the terminal; of course, the terminal can also determine it in other ways, for example, it can be specified by predefined rules.
预定义规则可以根据小区的中心频率对小区进行排序,例如可以按照中心频率由小到大进行排序,那么第j个小区的中心频率小于第j+1个小区的中心频率,或者可以按照中心频率由大到小进行排序,那么第j个小区的中心频率大于第j+1个小区的中心频率。The predefined rules can sort the cells according to the center frequency of the cell. For example, the center frequency can be sorted from small to large. Then the center frequency of the j-th cell is smaller than the center frequency of the j+1-th cell, or the center frequency can be sorted according to the center frequency. Sorting from large to small, then the center frequency of the j-th cell is greater than the center frequency of the j+1-th cell.
例如以4个小区为例,小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4,其中,f1>f2>f3>f4。若按照中心频率由小到大排序,那么第1个小区为小区#4,第2个小区为小区#3,第3个小区为小区#2,第4个小区为小区#1;若按照中心频率由大到小排序,那么第1个小区为小区#1,第2个小区为小区#2,第3个小区为小区#3,第4个小区为小区#4。For example, taking four cells as an example, the center frequency of cell #1 is f1, the center frequency of cell # 2 is f2, the center frequency of cell # 3 is f3, and the center frequency of cell #4 is f4, where f1>f2> f3>f4. If sorted according to the center frequency from small to large, then the first cell is cell #4, the second cell is cell # 3, the third cell is cell # 2, and the fourth cell is cell #1; if according to the center frequency The frequencies are sorted from large to small, then the first cell is cell #1, the second cell is cell # 2, the third cell is cell # 3, and the fourth cell is cell #4.
据此,可以根据小区的中心频率准确地确定小区的排序,进而可以第j个信息域调度的第j个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined according to the center frequency of the cells, and further, which cell is the j-th cell scheduled in the j-th information domain.
在一个实施例中,所述预定义规则规定第j个小区的中心频率对应的绝对无线频率信道编号ARFCN小于第j+1个小区的中心频率对应的ARFCN;或者,所述预定义规则规定第j个小区的中心频率对应的ARFCN大于第j+1个小区的中心频率对应的ARFCN。In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the jth cell is smaller than the ARFCN corresponding to the center frequency of the j+1th cell; or, the predefined rule stipulates that the The ARFCN corresponding to the center frequency of the j cell is greater than the ARFCN corresponding to the center frequency of the j+1th cell.
关于小区的ARFCN,网络设备可以根据小区的中心频率确定,也可以通过其他方式确定。Regarding the ARFCN of the cell, the network device can determine it based on the center frequency of the cell or by other methods.
预定义规则可以根据小区的ARFCN对小区进行排序,例如可以按照ARFCN由小到大进行排序,那么第j个小区的ARFCN小于第j+1个小区的ARFCN,或者可以按照ARFCN由大到小进行排序,那么第j个小区的ARFCN大于第j+1个小区的ARFCN。The predefined rules can sort the cells according to their ARFCN. For example, they can sort from small to large ARFCN, then the ARFCN of the jth cell is smaller than the ARFCN of the j+1th cell, or they can sort according to ARFCN from large to small. Sorting, then the ARFCN of the j-th cell is greater than the ARFCN of the j+1-th cell.
例如以4个小区为例,小区#1的ARFCN为ARFCN#1、小区#2的ARFCN为ARFCN#2、小区#3的ARFCN为ARFCN#3、小区#4的ARFCN为ARFCN#4,其中, ARFCN#1>ARFCN#2>ARFCN#3>ARFCN#4。若按照ARFCN由小到大排序,那么第1个小区为小区#4,第2个小区为小区#3,第3个小区为小区#2,第4个小区为小区#1;若按照ARFCN由大到小排序,那么第1个小区为小区#1,第2个小区为小区#2,第3个小区为小区#3,第4个小区为小区#4。For example, taking 4 cells as an example, the ARFCN of cell #1 is ARFCN#1, the ARFCN of cell # 2 is ARFCN# 2, the ARFCN of cell # 3 is ARFCN# 3, and the ARFCN of cell #4 is ARFCN#4, where, ARFCN#1>ARFCN# 2>ARFCN# 3>ARFCN#4. If sorted according to ARFCN from small to large, then the first cell is cell #4, the second cell is cell # 3, the third cell is cell # 2, and the fourth cell is cell #1; if according to ARFCN by Sorting from large to small, then the first cell is cell #1, the second cell is cell # 2, the third cell is cell # 3, and the fourth cell is cell #4.
据此,可以根据小区的ARFCN准确地确定小区的排序,进而可以第j个信息域调度的第j个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined according to the ARFCN of the cells, and further, which cell is the jth cell scheduled in the jth information domain.
在一个实施例中,所述多个信息域包括n个信息域,所述多个小区包括终端接收所述DCI时所在小区以及n-1个其他小区;所述预定义规则规定所述n个信息域中的第1个信息域与终端接收所述DCI时所在小区相关联,第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联,其中,2≤i≤n。In one embodiment, the multiple information domains include n information domains, and the multiple cells include the cell where the terminal is located when receiving the DCI and n-1 other cells; the predefined rules specify that the n The first information domain in the information domain is associated with the cell where the terminal is located when receiving the DCI, and the i-th information domain among the second to n-th information domains is associated with the i-th information domain in the n-1 other cells. i-1 other cells are associated, where 2≤i≤n.

For a certain type of information domain, n information domains can be set to schedule the n cells. The association relationship can be that the first information domain among the n information domains is associated with the cell where the terminal receives the DCI. The i-th information domain among the second to n-th information domains is associated with the i-1th other cell among the n-1 other cells. That is, for n-1 other cells, the association between the cell and the information domain is defined according to the same rules, and for the cell where the terminal is located when receiving the DCI, it is defined to be associated with the first information domain.

The number of bits occupied by the i-th information domain and the specific indication method are the same as the single DCI scheduling single cell method.
例如针对第1个小区至第n个小区这n个小区,若所述n个小区包括终端接收所述DCI时所在小区以及n-1个其他小区,以FDRA域采用separate指示方式为例,在DCI中可以设置n个FDRA域,预定义规则可以规定n个FDRA域中第1个FDRA 域与终端接收所述DCI时所在小区,在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中,第i个信息域与第i-1个其他小区相关联,若终端接收所述DCI时所在小区的小区id不在k
1至k
n-1之间,那么第i-1个小区的小区id可以为k

For example, for n cells from the 1st cell to the nth cell, if the n cells include the cell where the terminal receives the DCI and n-1 other cells, the ZP CSI-RS trigger field uses the separate indication method. For example, n ZP CSI-RS trigger domains can be set in DCI, and the predefined rules can stipulate that the first ZP CSI-RS trigger domain among the n ZP CSI-RS trigger domains is the same as the cell where the terminal receives the DCI.

所述第i个BWP域所占bits数根据通信协议38.212[2]中的机制确定,即:基于第i个小区的高层配置BWP数量n
BWP,RRC确定第i个BWP域所占bits数。
The number of bits occupied by the i-th BWP domain is determined according to the mechanism in communication protocol 38.212 [2], that is, the number of bits occupied by the i-th BWP domain is determined based on the high-level configuration BWP number n BWP of the i-th cell, and RRC .
其中,关于多个信息域的顺序,可以按照多个信息域占用比特bit的顺序从前到后以此确定,也即第i-1个信息域占用的比特在第i个信息域占用的比特之前。而关于多个小区的顺序,在后续实施例中说明如何确定。Among them, the order of multiple information fields can be determined from front to back according to the order of the bits occupied by the multiple information fields, that is, the bits occupied by the i-1th information field are before the bits occupied by the i-th information field. . Regarding the order of multiple cells, how to determine it will be described in subsequent embodiments.
以下通过几个实施例示例性说明,预定义规则按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系,如何确定多个小区的顺序。The following exemplifies how to determine the order of multiple cells by using several embodiments to illustrate how predefined rules stipulate the association between the cell where the terminal is located when receiving the DCI and other cells and the information domain according to different rules.
在一个实施例中,所述预定义规则规定第i-1个其他小区的标识小于第i个其他小区的标识;或者,所述预定义规则规定第i-1个其他小区的标识大于第i个其他小区的标识。In one embodiment, the predefined rule stipulates that the identity of the ith other cell is smaller than the identity of the ith other cell; or, the predefined rule stipulates that the identity of the ith other cell is greater than the ith other cell. identification of other communities.
关于小区的标识(例如Cell ID),网络设备可通过RRC信令进行指示,例如通过RRC信令中的ServcellIndex和/或SCellIndex等IE指示;而在小区的标识对应PCI,那么可以通过RRC信令中的信息元素PhysCellId指示;当然,终端也可以根据其他方式确定,例如可以为预定义规则规定的。Regarding the identity of the cell (such as Cell ID), the network device can indicate it through RRC signaling, for example, through IE indications such as ServcellIndex and/or SCellIndex in RRC signaling; and the identity of the cell corresponds to PCI, then it can be indicated through RRC signaling. The information element PhysCellId indicates; of course, the terminal can also be determined according to other methods, for example, it can be specified by predefined rules.
预定义规则可以根据小区的标识对小区进行排序,例如可以按照标识由小到大进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的标 识小于第i个其他小区的标识,若终端接收所述DCI时所在小区的小区id不在k

i;或者可以按照标识由大到小进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的标识大于第i个其他小区的标识,若终端接收所述DCI时所在小区的小区id不在k
1至k
n-1之间,k
i-1大于。
The predefined rules can sort the cells according to their identities. For example, they can sort the identities from small to large. Then the cell where the terminal is located when receiving the DCI is the 1st cell, and the i-1th other cell has an identity smaller than the 1st cell. Identities of i other cells, if the cell ID of the cell where the terminal is located when receiving the DCI is not between k 1 and k n-1 , k i-1 is smaller than k i ; or the identities can be sorted from large to small, then The cell where the terminal is located when receiving the DCI is the 1st cell, and the identity of the i-1th other cell is greater than the identity of the i-th other cell. If the cell ID of the cell where the terminal is receiving the DCI is not between k 1 and k n -1 , k i-1 is greater than.
例如以4个小区为例,分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4,其中小区#3为终端接收所述DCI时所在小区。若按照标识由小到大排序,那么第1个小区为小区#3,对于除了小区#3以外的其他小区,k
i-1小于k
i,第2个小区为小区#1,第3个小区为小区#2,第4个小区为小区#4;若按照标识由大到小排序,那么第1个小区为小区#3,对于除了小区#3以外的其他小区,k
i-1大于k
i,第2个小区为小区#4,第3个小区为小区#2,第4个小区为小区#1。
For example, taking four cells as an example, they are cell #1 with the identity of 1, cell # 2 with the identity of 2, cell # 3 with the identity of 3, and cell #4 with the identity of 4, where cell # 3 is the receiving location for the terminal. The community where DCI is described. If sorted from small to large by identifier, then the first cell is cell # 3. For other cells except cell # 3, k i-1 is smaller than k i . The second cell is cell #1, and the third cell is cell # 3. is cell # 2, and the fourth cell is cell #4; if sorted according to the identifier from large to small, then the first cell is cell # 3. For other cells except cell # 3, k i-1 is greater than k i , the second cell is cell #4, the third cell is cell # 2, and the fourth cell is cell #1.
据此,可以根据小区的标识准确地确定小区的排序,进而可以第i个信息域调度的第i个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined based on the identities of the cells, and further, which cell is the i-th cell scheduled in the i-th information domain.

关于小区的中心频率,网络设备通过向终端发送SSB进行指示;当然,终端也可以根据其他方式确定,例如可以为预定义规则规定的。Regarding the center frequency of the cell, the network device indicates it by sending SSB to the terminal; of course, the terminal can also determine it in other ways, for example, it can be specified by predefined rules.
预定义规则可以根据小区的中心频率对小区进行排序,例如可以按照中心频率由小到大进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的中心频率小于第i个其他小区的中心频率;或者可以按照中心频率由大到小进行排序,那么终端接收所述DCI时所在小区为第1个小区,第i-1个其他小区的中心频率大于第i个其他小区的中心频率。The predefined rules can sort the cells according to the center frequency of the cell. For example, the cells can be sorted according to the center frequency from small to large. Then the cell where the terminal is located when receiving the DCI is the 1st cell, and the center of the i-1th other cell. The frequency is smaller than the center frequency of the i-th other cell; or the center frequency can be sorted from large to small, then the cell where the terminal receives the DCI is the first cell, and the center frequency of the i-1 other cell is greater than the The center frequency of i other cells.
例如以4个小区为例,小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4,其中,f1>f2>f3>f4,小区#3为终端接收所述DCI时所在小区。若按照中心频率由小到大排序,那么第1个小区为小区#3,第2个小区为小区#4,第3个小区为小区#2,第4个小区为小区#1;若按照中心频率由大到小排序,那么第1个小区为小区#3,第2个小区为小区#1,第3个小区为小区#2,第4个小区为小区#4。For example, taking four cells as an example, the center frequency of cell #1 is f1, the center frequency of cell # 2 is f2, the center frequency of cell # 3 is f3, and the center frequency of cell #4 is f4, where f1>f2> f3>f4, cell # 3 is the cell where the terminal is located when receiving the DCI. If sorted according to the center frequency from small to large, then the first cell is cell # 3, the second cell is cell #4, the third cell is cell # 2, and the fourth cell is cell #1; if according to the center frequency The frequencies are sorted from large to small, then the first cell is cell # 3, the second cell is cell #1, the third cell is cell # 2, and the fourth cell is cell #4.
据此,可以根据小区的中心频率准确地确定小区的排序,进而可以第i个信息 域调度的第i个小区具体为哪个小区。Accordingly, the ordering of the cells can be accurately determined based on the center frequency of the cells, and then the specific cell of the i-th cell scheduled in the i-th information domain can be determined.
在一个实施例中,所述预定义规则规定第i-1个其他小区的中心频率对应的绝对无线频率信道编号ARFCN小于第i个其他小区的中心频率对应的ARFCN;或者,所述预定义规则规定第i-1个其他小区的中心频率对应的ARFCN大于第i个其他小区的中心频率对应的ARFCN。In one embodiment, the predefined rule stipulates that the absolute radio frequency channel number ARFCN corresponding to the center frequency of the i-1th other cell is smaller than the ARFCN corresponding to the center frequency of the i-th other cell; or, the predefined rule It is specified that the ARFCN corresponding to the center frequency of the i-1th other cell is greater than the ARFCN corresponding to the center frequency of the i-th other cell.
