Optionally, N may be the number of time slots included in a radio frame, or N may be less than the number of time slots included in a radio frame. For example, N is 1, 2, 3, 4 or other values. The time slot format (such as the first time slot format, the second time slot format) can indicate one or more of the following: the number of downlink symbols, the number of uplink symbols, the number of flexible symbols in a certain time slot, and The link transmission direction of a certain symbol in a certain time slot. Among them, the link transmission direction of symbols can be divided into: uplink (or represented by "U"), downlink (or represented by "D"), flexible (or represented by "F").

前述子带信息可以指示一个或多个子带(subband)。示例的，在本申请实施例中，一个子带在频域上可以占用一个或多个PRB(physical resource block，物理资源块)。该子带信息所指示的一个或多个子带可以包括于一个载波中，或者可以包括于一个BWP(Bandwidth Part，部分带宽)中。其中，该载波为该终端设备支持的载波，该载波例如为CC(component carrier，载波单元)，该BWP为该终端设备支持的BWP。例如，一个载波中可以配一个或多个子带，该一个或多个子带的大小(size，或称为带宽)可以相同，也可以不同。再例如，一个BWP中可以配一个或多个子带，该一个或多个子带的大小可以相同，也可以不同。可选的，一个载波中可以配一个或多个BWP。The aforementioned subband information may indicate one or more subbands.

The carrier is a carrier supported by the terminal device. The carrier is, for example, a CC (component carrier), and the BWP is a BWP supported by the terminal device. For example, one or more subbands may be allocated to a carrier, and the sizes (sizes, or bandwidths) of the one or more subbands may be the same or different. For another example, one or more subbands may be allocated to a BWP, and the sizes of the one or more subbands may be the same or different. Optionally, one or more BWPs can be configured in one carrier.
时隙格式信息与子带信息具有对应关系的含义为：该时隙格式信息所指示的时隙格式可以应用于该子带信息所指示的子带，或者，该子带信息所指示的子带的时隙格式为该时隙格式信息所指示的时隙格式。The meaning of the corresponding relationship between the time slot format information and the subband information is: the time slot format indicated by the time slot format information can be applied to the subband indicated by the subband information, or the subband indicated by the subband information. The time slot format of is the time slot format indicated by the time slot format information.
示例的，上述第一指示信息所指示的内容还可以描述为：第一指示信息用于指示时隙格式信息以及该时隙格式信息对应的子带信息，或者，第一指示信息用于指示子带信息以及该子带信息对应的时隙格式信息。其中，“时隙格式信息对应的子带信息”是指该时隙格式信息应用的频域位置，该频域位置的粒度为某个或某些子带。示例性的，以网络设备向终端设备指示时隙1的时隙格式应用的子带为子带1为例，“时隙1的时隙格式应用的子带为子带1”表示：终端设备可以在时隙1下使用子带1发送数据或接收数据，相应的，网络设备可以在时隙1下使用子带1接收来自终端设备的数据，或网络设备可以在时隙1下使用子带1向终端设备发送数据。“子带信息对应的时隙格式信息”是指子带信息所指示的子带的时隙格式通过该时隙格式信息来指示。For example, the content indicated by the above-mentioned first indication information can also be described as: the first indication information is used to indicate the time slot format information and the sub-band information corresponding to the time slot format information, or the first indication information is used to indicate the sub-band information. band information and the time slot format information corresponding to the sub-band information. Among them, "subband information corresponding to the time slot format information" refers to the frequency domain location to which the time slot format information is applied, and the granularity of the frequency domain location is a certain or certain subbands. For example, taking the network device indicating to the terminal device that the subband applied to the time slot format of time slot 1 is subband 1, "the subband applied to the time slot format of time slot 1 is subband 1" means: the terminal device Subband 1 can be used under time slot 1 to send data or receive data. Correspondingly, the network device can use subband 1 under time slot 1 to receive data from the terminal device, or the network device can use subband 1 under time slot 1. 1Send data to the terminal device. "The time slot format information corresponding to the subband information" means that the time slot format of the subband indicated by the subband information is indicated by the time slot format information.
上述可知，通过第一指示信息可以为终端设备配置子带级的时隙格式。相较于针对一个载波的所有频域资源在同一时刻下配置相同的时隙格式，本申请实施例通过为终端设备配置子带级的时隙格式，可以使得时隙格式的配置更加灵活，有利于更好地匹配不同业务的需求。As can be seen from the above, the subband-level time slot format can be configured for the terminal device through the first indication information. Compared with configuring the same time slot format for all frequency domain resources of a carrier at the same time, the embodiment of the present application can make the configuration of the time slot format more flexible by configuring the subband-level time slot format for the terminal device, and has Conducive to better matching the needs of different businesses.
示例性的，以一个无线帧包括10个时隙(slot)，并且载波包括3个子带，该3个子带分别为子带0、子带1、子带2为例，图3是针对一载波所有频域资源在同一时刻下均配置相同的时隙格式的示意图，图4是为终端设备配置子带级的时隙格式的4种示意图。图3和图4中，灰色填充方块表示链路传输方向为下行的时隙(或符号)，网格填充方块表示链路传输方向为上行的时隙(或符号)，斜线填充方块表示链路传输方向为上行或下行的时隙(或符号)。需要说明的是，图3和图4所示一个时隙中所有符号的链路传输方向均相同用于举例，对本申请实施例不构成限定，在具体实现中，一个时隙中可以包括上行符号、下行符号和灵活符号中的一种或多种。As an example, take a wireless frame including 10 time slots (slots), and a carrier including 3 subbands, which are subband 0, subband 1, and subband 2 respectively. Figure 3 is for a carrier A schematic diagram illustrating that all frequency domain resources are configured with the same time slot format at the same time. Figure 4 is a schematic diagram configuring four subband-level time slot formats for terminal equipment. In Figure 3 and Figure 4, the gray-filled squares represent the time slots (or symbols) in which the link transmission direction is downlink, the grid-filled squares represent the time slots (or symbols) in the uplink transmission direction, and the diagonally filled squares represent link The time slot (or symbol) in which the channel transmission direction is uplink or downlink. It should be noted that the link transmission directions of all symbols in one time slot shown in Figure 3 and Figure 4 are the same for examples and do not limit the embodiments of the present application. In specific implementations, one time slot may include uplink symbols. , one or more of descending symbols and flexible symbols.
如图3所示，每个子带的时隙格式均为：DDDFFFFUUU，在本申请实施例中，字母D、F、U可分别用于表示链路传输方向为下行、下行或上行、上行的时隙(或符号)。每个子带的时隙格式均相同(即每个子带在同一时刻下的链路传输方向均相同)，这意味着在同一时刻下终端设备只能进行上行传输要么进行下行传输。随着业务的多元化，不同业务对上下行的传输需求不同，针对同一载波不同频域资源在同一时刻下均配置相同的时隙格式， 不能满足不同业务的需求。As shown in Figure 3, the time slot format of each subband is: DDDFFFFUUU. In the embodiment of this application, the letters D, F, and U can be used to indicate when the link transmission direction is downlink, downlink or uplink, respectively. gap (or symbol). The time slot format of each subband is the same (that is, the link transmission direction of each subband at the same time is the same), which means that the terminal device can only perform uplink transmission or downlink transmission at the same time. With the diversification of services, different services have different transmission requirements for uplink and downlink. Different frequency domain resources of the same carrier are configured with the same time slot format at the same time. It cannot meet the needs of different businesses.
如图4所示的4种示意图，不同子带的时隙格式可以不同(即不同子带在同一时刻下的链路传输方向可以相同)，这样可以使得在同一时刻下在同一载波的不同子带上可以分别进行上行传输和下行传输。例如，在图4的第一种示意图中，在时隙0～时隙2下，通过子带0、子带2均可以进行下行传输，在时隙0～时隙2下，通过子带1可以进行上行传输。对于TDD(Time Division Duplexing，时分双工)***，采用此方式可实现子带全双工，即在同一时刻下通过同一载波可以同时进行上行传输和下行传输。As shown in the four schematic diagrams in Figure 4, the time slot formats of different subbands can be different (that is, the link transmission directions of different subbands at the same time can be the same), which allows different subbands of the same carrier to transmit data at the same time. Uplink transmission and downlink transmission can be performed separately on the tape. For example, in the first schematic diagram of Figure 4, under time slot 0 to time slot 2, downlink transmission can be carried out through subband 0 and subband 2, and under time slot 0 to time slot 2, through subband 1 Upstream transmission is possible. For TDD (Time Division Duplexing) systems, this method can be used to achieve subband full duplex, that is, uplink transmission and downlink transmission can be performed simultaneously through the same carrier at the same time.
S202、网络设备向终端设备发送该第一指示信息。相应的，终端设备接收该第一指示信息。S202. The network device sends the first instruction information to the terminal device. Correspondingly, the terminal device receives the first indication information.
网络设备确定第一指示信息，然后，向终端设备发送该第一指示信息。可选的，该第一指示信息可以携带于高层信令或DCI(Downlink Control Information，下行链路控制信息)。示例性的，高层信令可以为RRC(Radio Resource Control，无线资源控制)信令。The network device determines the first indication information, and then sends the first indication information to the terminal device. Optionally, the first indication information may be carried in higher layer signaling or DCI (Downlink Control Information). For example, the high-level signaling may be RRC (Radio Resource Control) signaling.
S203、终端设备根据第一指示信息，确定该时隙格式信息以及该子带信息。S203. The terminal device determines the time slot format information and the subband information according to the first indication information.
终端设备接收到第一指示信息，根据第一指示信息，可以确定时隙格式信息以及该时隙格式信息对应的子带信息，或者，可以确定子带信息以及该子带信息对应的时隙格式信息。The terminal device receives the first indication information, and according to the first indication information, can determine the time slot format information and the subband information corresponding to the time slot format information, or can determine the subband information and the time slot format corresponding to the subband information. information.
通过实施本申请实施例，通过第一指示信息可以为终端设备配置子带级的时隙格式。相较于针对一个载波的所有频域资源在同一时刻下配置相同的时隙格式，本申请实施例通过为终端设备配置子带级的时隙格式，可以使得时隙格式的配置更加灵活，有利于更好地匹配不同业务的需求。By implementing the embodiments of the present application, the subband-level time slot format can be configured for the terminal device through the first indication information. Compared with configuring the same time slot format for all frequency domain resources of a carrier at the same time, the embodiment of the present application can make the configuration of the time slot format more flexible by configuring the subband-level time slot format for the terminal device, and has Conducive to better matching the needs of different businesses.
网络设备配置时隙格式可采用以下3种方式中的任一种：The network device configuration time slot format can use any of the following three methods:
配置方式1：网络设备配置小区级时隙格式，小区级时隙格式是指针对某小区对应的时域资源均采用相同的时隙格式。例如，若小区a对应的时域资源包括3个载波，那么针对小区a所配置的小区级时隙格式适用于该3个载波。可选的，网络设备可以向终端设备发送RRC(Radio Resource Control，无线资源控制)信令，该RRC信令可以配置小区级时隙格式。Configuration method 1: The network device configures the cell-level time slot format. The cell-level time slot format means that the time domain resources corresponding to a certain cell all use the same time slot format. For example, if the time domain resources corresponding to cell a include three carriers, then the cell-level time slot format configured for cell a is applicable to the three carriers. Optionally, the network device can send RRC (Radio Resource Control) signaling to the terminal device, and the RRC signaling can configure the cell-level time slot format.
配置方式2：首先，网络设备采用配置方式1配置小区级时隙格式，然后在配置了小区级时隙格式的基础上，配置UE级时隙格式。UE级时隙格式是指针对小区内某个或某些UE所配置的，而小区级时隙格式是针对小区内所有UE配置的。可选的，网络设备可以向终端设备发送UE专用信令，该UE专用信令可以配置UE级时隙格式。Configuration method 2: First, the network device uses configuration method 1 to configure the cell-level timeslot format, and then configures the UE-level timeslot format based on the configured cell-level timeslot format. The UE-level timeslot format is configured for one or some UEs in the cell, while the cell-level timeslot format is configured for all UEs in the cell. Optionally, the network device can send UE-specific signaling to the terminal device, and the UE-specific signaling can configure the UE-level timeslot format.
配置方式3：首先，网络设备采用配置方式2先后配置小区级时隙格式、UE级时隙格式，然后，在配置了UE级时隙格式的基础上，配置动态时隙格式。动态时隙格式可以指示一个或多个载波上一个或多个时隙(slot)的时隙格式。可选的，网络设备可以向一组终端设备发送PDCCH(Physical Downlink Control Channel，物理下行控制信道)，该PDCCH上承载的DCI可以包括SFI(slot format indication，时隙格式指示)，SFI用于指示一个或多个载波上一个或多个时隙(slot)的时隙格式。Configuration method 3: First, the network device uses configuration method 2 to configure the cell-level time slot format and the UE-level time slot format successively. Then, based on the UE-level time slot format, configure the dynamic time slot format. The dynamic slot format may indicate the slot format of one or more slots on one or more carriers. Optionally, the network device can send a PDCCH (Physical Downlink Control Channel) to a group of terminal devices. The DCI carried on the PDCCH can include SFI (slot format indication). SFI is used to indicate The slot format of one or more slots on one or more carriers.
其中，网络设备通过配置方式1配置小区级时隙格式包括：通过图样1配置小区级时 隙格式，可选的，通过图样1和图样2共同配置小区级时隙格式。其中，图样1的时隙配置周期为P毫秒(ms)，图样2的时隙配置周期为P2毫秒。图样1和图样2中均包含如下信息：下行时隙的个数(用dslots表示)、下行时隙后下行符号的个数(用dsym表示)、上行时隙的个数(用uslots表示)、上行时隙前上行符号的个数(用usym表示)。图样1和图样2中dslots、dsym、uslots、usym的取值可以不同。示例性的，以P为10ms，且一个时隙为1ms为例，网络设备配置的图样1的示意图可以如图5所示。以P为4ms，P2为6ms，且一个时隙为1ms为例，网络设备配置的图样1和图样2的示意图可以如图6所示。Among them, the network device configures the cell-level time slot format through configuration method 1, including: configuring the cell-level time slot format through pattern 1. Slot format, optionally, configure the cell-level slot format through pattern 1 and pattern 2. Among them, the time slot configuration period of pattern 1 is P milliseconds (ms), and the time slot configuration period of pattern 2 is P2 milliseconds. Both Pattern 1 and Pattern 2 contain the following information: the number of downlink time slots (represented by d slots ), the number of downlink symbols after the downlink time slot (represented by d sym ), the number of uplink time slots (represented by u slots) Represented), the number of uplink symbols before the uplink time slot (expressed by u sym ). The values of d slots , d sym , u slots , and u sym in pattern 1 and pattern 2 can be different. For example, taking P as 10ms and one time slot as 1ms, the schematic diagram of pattern 1 of network device configuration can be shown in Figure 5 . Taking P as 4ms, P2 as 6ms, and one time slot as 1ms as an example, the schematic diagram of pattern 1 and pattern 2 configured by the network device can be shown in Figure 6.
UE级时隙格式仅重置小区级的灵活符号，不会修改小区级的DL或UL符号。网络设备通过配置方式2配置UE级时隙格式包括：针对每个时隙从下述三种指示中选择一种以进行UE级时隙格式配置：指示1：网络设备将该时隙中每个符号均配置为下行符号(if symbols＝allDownlink,all symbols in the slot are downlink)。指示2：网络设备将该时隙中每个符号均配置为上行符号(if symbols＝allUplink,all symbols in the slot are uplink)。指示3：网络设备通过UE专用信令中的参数1(nrofDownlinkSymbols)指示该时隙中的前几个符号重置为DL符号，并通过UE专用信令中的参数2(nrofUplinkSymbols)指示该时隙中的后几个符号重置为UL符号，该时隙中剩余的符号为灵活符号。若UE专用信令不携带参数1(nrofDownlinkSymbols)，那么该时隙中的第一个符号不是DL符号，若UE专用信令不携带参数2(nrofUplinkSymbols)，那么该时隙中的最后一个符号不是UL符号，该时隙中剩余的符号为灵活符号。上述可知，UE级时隙格式可以对每时隙均进行配置。需要说明的是，网络设备配置时隙格式的过程为：首先，网络设备将某符号配置为上行符号、下行符号或者灵活符号，然后该网络设备向终端设备发送指示信息(如第一指示信息、第二指示信息(见下文))，终端设备根据该指示信息可获知该符号为上行符号、下行符号或者灵活符号中的哪种类型。在本申请实施例中，根据网络设备配置的内容可相应的获知终端设备根据指示信息获知网络设备所配置的内容，或者，根据终端设备基于指示信息获取的内容相应的可获知网络设备配置的内容。The UE-level slot format only resets the cell-level flexible symbols and does not modify the cell-level DL or UL symbols. The network device configures the UE-level time slot format through configuration method 2, including: for each time slot, select one of the following three instructions to configure the UE-level time slot format: Instruction 1: The network device configures each time slot in the time slot. Symbols are configured as downlink symbols (if symbols=allDownlink, all symbols in the slot are downlink). Instruction 2: The network device configures each symbol in the slot as an uplink symbol (if symbols=allUplink, all symbols in the slot are uplink). Instruction 3: The network device indicates that the first few symbols in the time slot are reset to DL symbols through parameter 1 (nrofDownlinkSymbols) in the UE-specific signaling, and indicates the time slot through parameter 2 (nrofUplinkSymbols) in the UE-specific signaling The last few symbols in the slot are reset to UL symbols, and the remaining symbols in the slot are flexible symbols. If the UE-specific signaling does not carry parameter 1 (nrofDownlinkSymbols), then the first symbol in the timeslot is not a DL symbol. If the UE-specific signaling does not carry parameter 2 (nrofUplinkSymbols), then the last symbol in the timeslot is not a DL symbol. UL symbols, the remaining symbols in this slot are flexible symbols. It can be seen from the above that the UE-level time slot format can be configured for each time slot. It should be noted that the process of the network device configuring the time slot format is: first, the network device configures a certain symbol as an uplink symbol, a downlink symbol or a flexible symbol, and then the network device sends indication information (such as the first indication information, Second indication information (see below)), according to which the terminal device can learn which type of the symbol is an uplink symbol, a downlink symbol or a flexible symbol.

The UE-specific signaling can be carried in higher-layer signaling (such as RRC (Radio Resource Control, Radio Resource Control) signaling). UE-specific signaling may also be called UE-specific signaling. When the first indication information is used to configure a dynamic timeslot format, the first indication information may be carried in the DCI.

For example, the schematic diagram of "the first time slot format of a time slot has a corresponding relationship with a subband" can be seen in Figure 8. In Figure 8, the gray filled square represents the time slot in which the link transmission direction is downlink (or symbol), the grid-filled square represents the time slot (or symbol) in which the link transmission direction is uplink. In Figure 8, the first time slot format of each time slot in time slot 0 to time slot 4 corresponds to a subband (i.e., subband 0), and the first time slot format of each time slot in time slot 5 to time slot 9 Each slot format corresponds to one subband (i.e., subband 1).

The link transmission direction of the symbol; the link transmission direction of each symbol in the first time slot is the same, and the first time slot format of the first time slot has a corresponding relationship with a subband in the aforementioned subband information. In other words, when the link transmission directions of symbols in a certain time slot (such as the first time slot) are all in the same direction, the first time slot format of the time slot is applied to one subband. For example, the first time slot may be any time slot in FIG. 8 .
“一个时隙的第一时隙格式与子带信息中的多个子带具有对应关系”表示：针对一个时隙配置的第一时隙格式应用于多个子带，即在该时隙内存在子带切换。针对一个时隙配置的第一时隙格式是指针对该时隙内的符号配置的时隙格式，“针对一个时隙配置的第一时隙格式应用于多个子带”可以表示：针对一个时隙中的部分符号配置的第一时隙格式所应用的子带，可以与针对该时隙中的另一部分配置的第一时隙格式所应用的子带不同。可选的，前述N个时隙包括第二时隙；该第二时隙的第一时隙格式用于指示第二时隙内的符号的链路传输方向；第二时隙内至少存在两个符号的链路传输方向不同，第二时隙的第一时隙格式与前述子带信息中的一个或多个子带具有对应关系。示例性的，“一个时隙的第一时隙格式与子带信息中的多个子带具有对应关系”的示意图可以参见图9所示，图9中，灰色填充方块表示链路传输方向为下行的时隙(或符号)，网格填充方块表示链路传输方向为上行的时隙(或符号)。图9中，时隙4中的前7个符号与同一个子带对应(即符号0～6与子带0对应)，时隙4中的后7个符号与另一个子带对应(即符号7～13与子带1对应)，即时隙4对应两个子带，在时隙4中存在子带切换(从子带0切换至子带1)。"The first time slot format of a time slot has a corresponding relationship with multiple subbands in the subband information" means: the first time slot format configured for one time slot applies to multiple subbands, that is, there are subbands in the time slot. With switch. The first time slot format configured for a time slot refers to the time slot format configured for symbols in the time slot. "The first time slot format configured for a time slot applies to multiple subbands" can mean: for a time slot The subband applied by the first time slot format configured for part of the symbols in the slot may be different from the subband applied by the first time slot format configured for another part of the time slot. Optionally, the aforementioned N time slots include a second time slot; the first time slot format of the second time slot is used to indicate the link transmission direction of the symbol in the second time slot; there are at least two timeslots in the second time slot. The link transmission directions of the symbols are different, and the first time slot format of the second time slot has a corresponding relationship with one or more subbands in the aforementioned subband information. For example, the schematic diagram of "the first time slot format of a time slot has a corresponding relationship with multiple subbands in the subband information" can be seen in Figure 9. In Figure 9, the gray filled square indicates that the link transmission direction is downlink. The time slots (or symbols) of the grid represent the time slots (or symbols) in which the link transmission direction is uplink. In Figure 9, the first 7 symbols in slot 4 correspond to the same subband (i.e., symbols 0 to 6 correspond to subband 0), and the last 7 symbols in slot 4 correspond to another subband (i.e., symbol 7 ~13 corresponds to subband 1), that is, slot 4 corresponds to two subbands, and there is subband switching (switching from subband 0 to subband 1) in slot 4.

In other words, symbols with different link transmission directions correspond to different subbands. For example, in Figure 9, the link transmission directions of symbols 0 to 6 are different from the link transmission directions of symbols 7 to 13. The subbands corresponding to symbols 0 to 6 are different from the subbands corresponding to symbols 7 to 13. Symbols 0 to 6 Corresponds to subband 0, and symbols 7 to 13 correspond to subband 1. The number of the first symbol and the number of the second symbol may be one or more. The link transmission directions of both the first symbol and the second symbol may be uplink or downlink.

As an example, taking the network device configuring the subband-level time slot format for terminal device 1 and terminal device 2, the network device can send UE-specific signaling 1 to terminal device 1 and send UE-specific signaling 1 to terminal device 2. Signaling 2. The UE-specific signaling 1 is used to configure a sub-band-level time slot format for the terminal device 1, and the UE-specific signaling 2 is used to configure a sub-band-level time slot format for the terminal device 2. The subband-level time slot format configured for terminal device 1 may be the same as or different from the subband-level time slot format configured for terminal device 2, and this is not limited in the embodiment of the present application. It should be noted that the terminal devices may not know the sub-band-level time slot format configured by the network device for other terminal devices. For example, the aforementioned terminal device 1 does not know the sub-band-level time slot configured by the network device for terminal device 2. Format. It should also be noted that when one carrier includes multiple subbands, the terminal device only learns the time slot format information, subband information, and the time slot format information and the subband information indicated by the network device through the first indication information. There is a corresponding relationship. For example, in Figure 8, although the terminal device can use subband 0 and subband 1, for the terminal device, the terminal device only learns that subband 0 can be used for downlink transmission in time slots 0 to 4, and in Time slots 5 to 9 can use subband 1 for uplink transmission.
在一种实现方式中，前述第一指示信息可以包括：第一索引和第二索引，第一索引用于指示前述时隙格式信息，第二索引用于指示前述子带信息；其中，第一索引对应第一集合，第一集合包括前述N个时隙的第一时隙格式；第二索引对应第二集合，第二集合包括N组子带索引，每组子带索引与该N个时隙中一个时隙的第一时隙格式具有对应关系，每组子带索引包括一个或多个子带的索引。In an implementation manner, the aforementioned first indication information may include: a first index and a second index, the first index is used to indicate the aforementioned time slot format information, and the second index is used to indicate the aforementioned subband information; wherein, the first index The index corresponds to the first set, and the first set includes the first time slot format of the aforementioned N time slots; the second index corresponds to the second set, and the second set includes N groups of subband indexes, and each group of subband indexes is related to the N time slots. The first time slot format of a time slot in the slot has a corresponding relationship, and each group of subband indexes includes the index of one or more subbands.
其中，该第一集合可以包含于前述UE专用表格(例如表2所示)，该第一集合可以为前述UE专用表格中的一个时隙格式集合，即第一集合为前述UE专用表格中的一行数据。第一索引为UE专用表格中的索引。例如，表2中一个时隙格式集合包括N个时隙格式索引，一个时隙格式索引为N个时隙中的一个时隙的第一时隙格式在表1所示的时隙格式总表中的索引。Wherein, the first set may be included in the aforementioned UE-specific table (for example, as shown in Table 2), and the first set may be a time slot format set in the aforementioned UE-specific table, that is, the first set is a time slot format set in the aforementioned UE-specific table. A row of data. The first index is an index in the UE-specific table. For example, a time slot format set in Table 2 includes N time slot format indexes, and a time slot format index is the first time slot format of one time slot among the N time slots. The total list of time slot formats shown in Table 1 is index in .
该第二集合可以包含于子带索引表格。子带索引表格可以包括一个多个子带索引集合，该第二集合为其中的一个子带索引集合，第二索引为子带索引表格中的索引。示例性的，子带索引表格可以如表3所示。The second set may be contained in a subband index table. The subband index table may include a plurality of subband index sets, the second set is one of the subband index sets, and the second index is an index in the subband index table. By way of example, the subband index table may be as shown in Table 3.
表3子带索引表格
Table 3 subband index table
表3中，子带索引集合中的每个子带索引后括号内的数字为某个或某些子带的索引。例如，子带索引(0)表示索引值为0的子带(即子带0)，子带索引(1)表示索引值为1的子带(即子带1)，子带索引(2)表示索引值为2的子带(即子带2)，以此类推。其中，子带索引(0、1)表示子带0和子带1。In Table 3, the number in parentheses after each subband index in the subband index set is the index of one or some subbands. For example, subband index (0) represents the subband with index value 0 (i.e., subband 0), subband index (1) represents the subband with index value 1 (i.e., subband 1), and subband index (2) Represents the subband with index value 2 (i.e. subband 2), and so on. Among them, the subband index (0, 1) represents subband 0 and subband 1.
可以理解的是，第一集合中的一个时隙格式索引与第二集合中的一组子带索引具有关系。示例性的，以第一集合为表2中索引2对应的时隙格式集合，第二集合为表3中索引2对应的子带索引集合为例，其中，“时隙格式索引(3)”与“子带索引(1)”对应，“时隙格式索引(10)”与“子带索引(0、1)”对应，…。其中，“时隙格式索引(3)”与“子带索引(1)”对应的含义为：N个时隙中第一个时隙的时隙格式的索引为3，且该第一个时隙的时隙格式应用于子带1。“时隙格式索引(10)”与“子带索引(0、1)”对应的含义为：N个时隙中第二个时隙的时隙格式的索引为10，且该第二个时隙的时隙格式应用于子带0和子带1，结合表1中时隙格式索引为10对应的“单个时隙格式”(符号0为下行符号，符号13为上行符号，其余符号为灵活符号)可知，在第二个时隙的符号0上可通过子带0进行下行传输，在第二个时隙的符号13上可通过子带1进行上行传输。It can be understood that one slot format index in the first set has a relationship with a set of subband indexes in the second set. As an example, take the first set as the time slot format set corresponding to index 2 in Table 2, and the second set as the subband index set corresponding to index 2 in Table 3, where, "time slot format index (3)" Corresponds to “subband index (1)”, “slot format index (10)” corresponds to “subband index (0, 1)”,…. Among them, the corresponding meaning of "slot format index (3)" and "subband index (1)" is: the slot format index of the first time slot among N time slots is 3, and the first time slot The slot format of slot applies to subband 1. The corresponding meaning of "slot format index (10)" and "subband index (0, 1)" is: the slot format index of the second time slot among N time slots is 10, and the second time slot The slot format of the slot applies to subband 0 and subband 1, combined with the "single slot format" corresponding to the slot format index 10 in Table 1 (symbol 0 is the downlink symbol, symbol 13 is the uplink symbol, and the remaining symbols are flexible symbols ), it can be seen that downlink transmission can be performed through subband 0 on symbol 0 of the second time slot, and uplink transmission can be performed on subband 1 on symbol 13 of the second time slot.
可选的，第一索引可以通过时隙格式字段指示，第二索引可通过在DCI中增加的子带索引字段指示。例如，在DCI format 2_0中增加子带索引字段。Optionally, the first index may be indicated by the slot format field, and the second index may be indicated by the subband index field added in the DCI. For example, add a subband index field in DCI format 2_0.

The number of subband indexes corresponding to the first time slot format of a time slot may be one or more. If there are multiple subband indexes, it indicates that there is subband switching in the time slot. The third set may be included in a joint indication table. The joint indication table may include one or more joint indication sets, the third set is one of the joint indication sets, and the third index is an index in the joint indication table. The joint instruction table may be as shown in Table 4.
表4联合指示表格
Table 4 Joint Instruction Form
联合指示表格可以理解为UE专用表格和子带索引表格的结合。联合指示表格中的一个联合指示集合可以为：UE专用表格中的一个时隙格式集合，与子带索引表格中的一个子带索引集合的结合。The joint indication table can be understood as a combination of the UE-specific table and the subband index table.
