技术领域Technical field
本申请涉及通信技术领域，尤其涉及信道传输方法及装置、计算机存储介质。The present application relates to the field of communications technologies, and in particular, to a channel transmission method and apparatus, and a computer storage medium.
背景技术Background technique
长期演进(Long Term Evolution，LTE)***的物理下行控制信道(Physical Downlink Control CHannel，PDCCH)用于承载调度信息以及其他控制信息。每个下行子帧的控制区域内可以有多个PDCCH，控制区域的大小由物理控制模式指示信道(Physical Control Format Indicator CHannel，PCFICH)决定，占1～4个正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号。一个控制信道的传输占用一个控制信道单元(Control Channel Element，CCE)或者多个连续的CCE，每个CCE由9个资源单元组(Resource Element Group，REG)组成，且PDCCH的CCE所包含的REG为没有用于承载PCFICH和PHICH的REG。用户设备(User Equipment，UE)在不是非连续接收(nondiscontinuous reception，non-DRX)子帧监听PDCCH候选资源位置(candidate)集合，即根据所要监听的下行控制信息(Downlink Control Information，DCI)模式(format)来尝试解码搜索空间中的每一个PDCCH。The Physical Downlink Control CHannel (PDCCH) of the Long Term Evolution (LTE) system is used to carry scheduling information and other control information. There may be multiple PDCCHs in the control region of each downlink subframe, and the size of the control region is determined by a Physical Control Format Indicator CHannel (PCFICH), which occupies 1 to 4 orthogonal frequency division multiplexing (Orthogonal Frequency). Division Multiplex, OFDM) symbol. The transmission of one control channel occupies one Control Channel Element (CCE) or multiple consecutive CCEs, each CCE is composed of 9 Resource Element Groups (REGs), and the REGs included in the CCE of the PDCCH There is no REG for carrying PCFICH and PHICH. The user equipment (User Equipment, UE) monitors the PDCCH candidate resource location (candidate) set in a non-continuous reception (non-DRX) subframe, that is, according to the Downlink Control Information (DCI) mode to be monitored (Downlink Control Information (DCI) mode ( Format) to attempt to decode each PDCCH in the search space.
为了扩展PDCCH的容量，在版本11(Rel-11)引入了演进的PDCCH(EPDCCH)。EPDCCH在子帧中的数据区域进行传输，不能占用PDCCH的传输空间。配置了EPDCCH的终端在每个子帧中配置的物理资源块(Physical Resource Block，PRB)设置(set)内检测接收EPDCCH。In order to extend the capacity of the PDCCH, an evolved PDCCH (EPDCCH) is introduced in Release 11 (Rel-11). The EPDCCH is transmitted in a data area in a subframe, and cannot occupy the transmission space of the PDCCH. The terminal configured with the EPDCCH detects the received EPDCCH within a physical resource block (PRB) set (set) configured in each subframe.
对于增强的机器类型通信(Enhanced Machine Type Communication，EMTC)UE，其在高层配置的一个或者多个子帧(subframe)上检测接收机器PDCCH(Machine PDCCH，MPDCCH)。For an Enhanced Machine Type Communication (EMTC) UE, it detects a Receiver PDCCH (MPDCCH) on one or more subframes of a higher layer configuration.
在现有LTE***中，传输时间间隔(Transmitted Time Interval，TTI)长度固定为1ms，且一个或者多个PDCCH在每个TTI的前N个OFDM符号上传输或者在数据区域的一组PRB对(pair)上传输或者在多个连续或不连续的子帧上传输，UE根据期望得到的信息在每个non-DRX子帧的公共搜索空间(Common Search Space，CSS)以及用户设备的搜索空间(UE-specific Search Space，USS)上盲检自己的PDCCH。无论在CSS中传输的下行控制信道还是在USS中传输的下行控制信道均采用整个频域上的所有公共参考信号(Common Reference Signal，CRS)作为解调导频。在5G***中，不同的搜索空间具有不同的盲检周期，而且不同类型搜索空间中传输的下行控制信道解调时所采用的解调参考信号(Demodulation Reference Signal，DMRS)导频结构不同。In the existing LTE system, the Transmitted Time Interval (TTI) length is fixed to 1 ms, and one or more PDCCHs are transmitted on the first N OFDM symbols of each TTI or a set of PRB pairs in the data region ( On a pair of transmissions or on multiple consecutive or discontinuous subframes, the UE obtains information in the common search space (CSS) of each non-DRX subframe and the search space of the user equipment according to the desired information ( The UE-specific Search Space (USS) blindly checks its own PDCCH. Both the downlink control channel transmitted in the CSS and the downlink control channel transmitted in the USS use all common reference signals (CRS) in the entire frequency domain as demodulation pilots. In the 5G system, different search spaces have different blind detection periods, and the demodulation reference signal (DMRS) pilot structure used in demodulation of the downlink control channel transmitted in different types of search spaces is different.

本申请实施例提供了信道传输方法及装置、计算机存储介质，用以使得终端可以确定控制资源集合内存在的搜索空间类型，并进而基于确定的搜索空间类型实现在控制资源集合内的信道传输。The embodiment of the present application provides a channel transmission method and apparatus, and a computer storage medium, to enable a terminal to determine a search space type existing in a control resource set, and further implement channel transmission in a control resource set based on the determined search space type.
在LTE***中，终端需要在每个non-DRX子帧(subframe)内的CSS和用户设备的USS上检测接收下行控制信道。在未来5G***中，用于传输下行控制信道的控制资源集合可能只存在USS，或者只存在CSS，或者同时存在CSS和USS。而且在CSS中传输的下行控制信道和在USS中传输的下行控制信道解调时采用的DMRS导频结构不同，以及采用的波束方向也不同，例如DMRS相关的准共址(Quasi-Co-Location，QCL)不同。本申请实施例提供的技术方案，给出了如何通知终端CORESET内存在的搜索空间类型，以及，终端如何检测接收下行控制信道。In the LTE system, the terminal needs to detect and receive the downlink control channel on the CSS in each non-DRX subframe and the USS of the user equipment. In the future 5G system, the set of control resources used to transmit the downlink control channel may exist only in the USS, or only the CSS, or both the CSS and the USS. Moreover, the downlink control channel transmitted in the CSS is different from the DMRS pilot structure used in demodulating the downlink control channel transmitted in the USS, and the beam direction used is also different, for example, DMRS-related quasi-co-location (Quasi-Co-Location) , QCL) is different. The technical solution provided by the embodiment of the present application provides how to notify the terminal of the type of search space existing in the CORESET, and how the terminal detects and receives the downlink control channel.
基站通过显式信令配置控制资源集合(COntrol REsource SET，CORESET)内存在的搜索空间类型，并通过显式信令配置通知的方式或者协议预定义的方式，使得终端确定在CORESET检测接收下行控制信道的顺序。The base station configures the search space type of the control resource set (COntrol REsource SET, CORESET) through explicit signaling, and configures the notification mode or the protocol predefined manner by explicit signaling, so that the terminal determines the downlink control in the CORESET detection and reception. The order of the channels.

The detection receives different types of downlink control channels.
例如，终端接收基站发送的无线资源控制(Radio Resource Control，RRC)信令(signaling)，确定CORESET内存在的搜索空间类型。For example, the terminal receives Radio Resource Control (RRC) signaling sent by the base station, and determines the type of search space that exists in the CORESET.
具体地，基站通过RRC signaling通知终端CORESET存在USS或者CSS或者G-CSS或者同时存在三者中的任意组合。Specifically, the base station notifies the terminal CORESET that there is USS or CSS or G-CSS through RRC signaling or any combination of the three.
或者，例如基站通过剩余***信息(Remaining system information，RMSI)通知终端，传输调度RMSI的PDCCH的CORESET内是否存在USS。Or, for example, the base station notifies the terminal by Remaining System Information (RMSI) whether the USS exists in the CORESET of the PDCCH that schedules the RMSI.
当传输调度RMSI的PDCCH的CORESET内存在USS时，该USS在由协议预定义的一组物理资源上传输，该物理资源例如包括CORESET内的N个逻辑CCE。USS内包含的PDCCH candidate个数以及种类，可以通过协议预定义。例如：聚合等级(Aggregation level，AL)＝1的PDCCH candidate有M1个，AL＝2的PDCCH candidate有M2个。其中，M1和M2为正整数。When the CORESET of the PDCCH scheduling the RMSI is transmitted in the USS, the USS is transmitted on a set of physical resources predefined by the protocol, which includes, for example, N logical CCEs within the CORESET. The number and type of PDCCH candidates included in the USS can be predefined by a protocol. For example, there are M1 PDCCH candidates with Aggregation level (AL)=1, and M2 PDCCH candidates with AL=2. Where M1 and M2 are positive integers.
或者，当传输RMSI的PDCCH的CORESET内存在USS时，所述USS在由基站通知的一组物理资源上传输，例如通过RMSI或者RAR通知组成所述USS的逻辑CCE编号的起始位置，或者偏移值，或者具体的CCE索引(index)。更进一步的，在USS内传输的PDCCH candidate的AL以及数量也可以通过基站显式通知给终端或者预定义好。Or, when the CORESET of the PDCCH transmitting the RMSI exists in the USS, the USS is transmitted on a group of physical resources notified by the base station, for example, by using RMSI or RAR to notify the start position of the logical CCE number that constitutes the USS, or The value is shifted, or the specific CCE index (index). Further, the AL and the number of PDCCH candidates transmitted in the USS may also be explicitly notified to the terminal by the base station or predefined.
或者，例如基站通过随机接入过程中的随机接入响应(Random Access Response，RAR)，通知终端传输调度RMSI的PDCCH的CORESET内是否存在USS。Or, for example, the base station informs the terminal whether the USS exists in the CORESET of the PDCCH that schedules the RMSI by using a random access response (RAR) in the random access procedure.
当传输调度RMSI的PDCCH的CORESET内存在USS时，所述USS由协议预定义的PDCCH candidate组成。When the CORESET of the PDCCH for scheduling the RMSI is transmitted in the USS, the USS is composed of a PDCCH candidate predefined by the protocol.
或者，当传输RMSI的PDCCH的CORESET内存在USS时，所述USS包含的PDCCH candidate由基站通知，例如通过RAR通知组成所述USS的具体PDCCH candidate。Alternatively, when the CORESET of the PDCCH transmitting the RMSI exists in the USS, the PDCCH candidate included in the USS is notified by the base station, for example, by the RAR to notify the specific PDCCH candidate that constitutes the USS.
综上，可选地，当用于传输调度RMSI的PDCCH的控制资源集合内存在的所述搜索空间类型包括USS时，所述USS在预定义的或网络侧通知的物理资源上传输。In summary, optionally, when the search space type existing in the control resource set of the PDCCH for transmitting the scheduled RMSI includes the USS, the USS is transmitted on a physical resource that is predefined or notified by the network side.

当一个CORESET内存在多种类型的下行控制信道时，终端按照预定义的顺序检测接收下行控制信道，例如首先检测接收P1，其次检测接收P2，然后检测接收P3，最后检测接收P4。When there are multiple types of downlink control channels in a CORESET, the terminal detects and receives the downlink control channel in a predefined order, for example, first detecting the reception P1, then detecting the reception P2, then detecting the reception P3, and finally detecting the reception P4.
一个CORESET内可以存在P1～P4中的部分，也可以包含其他的下行控制信道，在此不做限定。A part of P1 to P4 may exist in a CORESET, and other downlink control channels may be included, which is not limited herein.
另外，需要说明的是，预定义的检测接收顺序并不仅限于如上顺序，不排除其他检测接收顺序，可以根据实际需要而定。In addition, it should be noted that the predefined detection and reception order is not limited to the above sequence, and other detection reception orders are not excluded, and may be determined according to actual needs.
或者，当一个CORESET内存在多种类型的下行控制信道时，终端按照基站通知的顺序检测不同类型的下行控制信道。Alternatively, when there are multiple types of downlink control channels in a CORESET, the terminal detects different types of downlink control channels in the order notified by the base station.
基站可以通过高层信令，或者RMSI，或者RAR，通知终端检测接收下行控制信道的顺序。The base station can notify the terminal to detect the order of receiving the downlink control channel through high layer signaling, or RMSI, or RAR.
例如，***中共存在N种不同的下行控制信道类型，例如取N＝4，则终端可以通过N*ceil(log2(N))bit指示检测接收顺序，以如上检测接收顺序为例，参见下面的表一，该指示域为00 01 10 11。For example, there are N different types of downlink control channel types in the system. For example, if N=4, the terminal can detect the receiving sequence through the N*ceil (log2(N)) bit. For example, the receiving sequence is as follows. Table 1, the indication field is 00 01 10 11.

For example, the four sequences shown in Table 2 below are predefined. Then, the base station instructs the terminal to detect the order of receiving the downlink control channel in one CORESET through the 2-bit information.

下面给出一些具体实施例的举例说明。An illustration of some specific embodiments is given below.
实施例1：Example 1:
基站通过UE specific RRC signaling通知终端CORESET内存在的搜索空间类型。例如基站通过2bit信息通知一个CORESET内存在的搜索空间类型。如下面的表三所示。即00表示CORESET内只存在USS，01表示CORESET内只存在CSS，10表示CORESET内同时存在USS和CSS。The base station notifies the type of search space existing in the terminal CORESET by UE specific RRC signaling. For example, the base station notifies the type of search space existing in a CORESET through 2-bit information. As shown in Table 3 below. That is, 00 means that only USS exists in CORESET, 01 means that only CSS exists in CORESET, and 10 means that both USS and CSS exist in CORESET.
表三：Table 3:
bit域Bit field 含义meaning
0000 只有USSOnly USS
0101 只有CSSOnly CSS
1010 同时存在USS和CSSThere are both USS and CSS
1111 reservedReserved
进一步的，基站通过RRC signaling通知终端CSS和USS的CCE index起始位置。Further, the base station notifies the CCE index start position of the terminal CSS and the USS through RRC signaling.
当CORESET存在多种搜索空间时，终端需要检测接收不同类型的下行控制信道。例如，可以包括如下控制信道类型：When there are multiple search spaces for CORESET, the terminal needs to detect and receive different types of downlink control channels. For example, the following control channel types can be included:
承载RMSI调度信息或者Paging调度信息或者RAR调度信息的common PDCCH或group common PDCCH，为方便记为P1；a common PDCCH or a group common PDCCH carrying RMSI scheduling information or Paging scheduling information or RAR scheduling information, which is conveniently recorded as P1;
承载SFI的group common PDCCH，为方便记为P2；The group common PDCCH carrying the SFI is conveniently recorded as P2;
承载数据调度信息的UE-specific PDCCH，为方便记为P3；The UE-specific PDCCH carrying the data scheduling information is conveniently recorded as P3;
承载其他信息(例如pre-emption indication，power control indication)的 group common PDCCH，为方便记为P4。The group common PDCCH carrying other information (for example, pre-emption indication, power control indication) is conveniently referred to as P4.
在这种情况下，终端检测接收不同类型的下行控制信道的顺序，可以通过如下方式确定：In this case, the terminal detects the order of receiving different types of downlink control channels, which can be determined as follows:
方式1：终端检测接收下行控制信道的顺序通过协议预定义的方式确定，例如，终端首先检测接收P1，其次检测接收P2，然后检测接收P3，最后检测接收P4。当然，预定义的顺序不限于此。另外，本申请实施例提供的技术方案，并不限定于所有所述4种下行控制信道类型均出现在同一个CORESET内，例如也可以只存在P1和P3，则终端首先检测接收P1，其次检测接收P3。Mode 1: The terminal detects the order in which the downlink control channel is received. The sequence is determined by a protocol in a predefined manner. For example, the terminal first detects the reception P1, secondly detects the reception P2, then detects the reception P3, and finally detects the reception P4. Of course, the predefined order is not limited to this. In addition, the technical solution provided by the embodiment of the present application is not limited to all the four downlink control channel types appearing in the same CORESET. For example, only P1 and P3 may exist, the terminal first detects the receiving P1, and then detects the second. Receive P3.
方式2：终端根据基站配置的下行控制信道检测接收顺序，检测接收下行控制信道。以P1、P2、P3、P4为例，可以通过如下两种方式中的一种确定检测接收下行控制信道的顺序。Manner 2: The terminal detects the receiving downlink control channel according to the downlink control channel detection receiving sequence configured by the base station. Taking P1, P2, P3, and P4 as an example, the order of detecting and receiving the downlink control channel may be determined by one of the following two methods.
基站通过8bit信息指示检测顺序，最高位表示优先级最高的下行控制信道类型，最低位表示优先级最低的下行控制信道类型。例如00表示P1，01代表P2，10代表P3，11代表P4。如果基站通知的检测接收顺序为P1 P2 P3 P4，则所述8bit信息为00011011。The base station indicates the detection sequence by using 8-bit information, the highest bit indicates the downlink control channel type with the highest priority, and the lowest bit indicates the downlink control channel type with the lowest priority. For example, 00 means P1, 01 means P2, 10 means P3, and 11 means P4. If the detection reception order notified by the base station is P1 P2 P3 P4, the 8-bit information is 00011011.
基站通过指示表格index的方式指示一个检测接收顺序的组合。例如，***中预定义4中检测接收顺序，具体如下表四所示。基站通过2bit指示信息指示四种下行控制信道检测接收顺序。The base station indicates a combination of detection reception orders by indicating the index of the table. For example, in the system, the detection order is detected in the predefined 4, as shown in Table 4 below. The base station instructs the four downlink control channels to detect the receiving sequence by using the 2 bit indication information.

实施例2：Example 2:
如实施例1，其中通知下行控制信道检测接收顺序的信令，可以通过RMSI或者RAR进行承载。As in Embodiment 1, the signaling informing the downlink control channel to detect the reception order may be carried by RMSI or RAR.
实施例3：Example 3:
基站通知终端传输调度RMSI的PDCCH的CORESET内存在UE专属搜索空间(UE specific search space，UESS)。基站可以通过RMSI或者RAR通知所述CORESET内存在UESS。例如通过1bit指示信息指示是否存在UESS。The base station notifies the terminal to transmit the CORESET of the PDCCH scheduling RMSI in the UE specific search space (UES). The base station can notify the CORESET that the UESS is present in the UESS through the RMSI or RAR. For example, the 1 bit indication information indicates whether a UESS exists.
UESS在用于传输调度RMSI的PDCCH的CORESET(RMSI-CORESET)内包含的PDCCH candidate的数目以及位置由协议预定义。例如，协议规定在RMSI-CORESET内的USS，包含的PDCCH candidate的AL分别为4和8，且每个AL下的candidate数目分别为4和4。且起始位置从该CORESET内的第一个逻辑CCE开始。The number and location of PDCCH candidates included in the COESS (RMSI-CORESET) of the PDCCH used to transmit the scheduled RMSI are predefined by the protocol. For example, the protocol specifies USS within RMSI-CORESET, the ALs of the PDCCH candidates included are 4 and 8, respectively, and the number of candidates per AL is 4 and 4, respectively. And the starting position starts from the first logical CCE in the CORESET.
或者，UESS在RMSI-CORESET内包含的PDCCH candidate的数目以及位置由物理广播信道(PhysicalBroadcastingChannel，PBCH)或者RAR通知。例如PBCH或者RAR通知终端在RMSI-CORESET内的UESS包含的PDCCH candidate的起始位置，包含的candidate个数等。Alternatively, the number and location of PDCCH candidates included in the RMSI-CORESET by the UESS are notified by a Physical Broadcasting Channel (PBCH) or RAR. For example, the PBCH or the RAR informs the terminal of the start position of the PDCCH candidate included in the UESS in the RMSI-CORESET, the number of candidates included, and the like.
当所述RMSI-CORESET内包含多种下行控制信道类型时，终端根据如实施例1中所述的方法确定检测接收下行控制信道的顺序。When the RMSI-CORESET includes multiple downlink control channel types, the terminal determines the order of detecting and receiving the downlink control channel according to the method as described in Embodiment 1.
实施例4：Example 4:
如实施例1-3，终端确定下行控制信道的盲检顺序之后，按照确定的盲检顺序检测接收下行控制信道。终端检测接收到下行控制信道后，不再进行后续其他类型下行控制信道的检测接收。As in Embodiment 1-3, after determining the blind detection sequence of the downlink control channel, the terminal detects the received downlink control channel according to the determined blind detection sequence. After receiving the downlink control channel, the terminal does not perform detection and reception of subsequent downlink control channels.
