Description

无线通信的方法、终端设备和网络设备Wireless communication method, terminal equipment and network equipment 技术领域Technical field

背景技术Background technique

网络设备可以通过下行控制信息(Downlink Control Information，DCI)中的3比特的指示域结合媒体接入控制控制元素(Media Access Control Control Element，MAC CE)指示的激活的TCI状态来确定网络所配置的TCI状态，具体地，可以根据DCI中的3比特的指示域的取值和激活的TCI状态的顺序具有对应关系，可以将激活的TCI状态中所述取值对应的顺序的TCI状态确定为网络配置的目标TCI状态。例如，若激活的TCI状态包括T0，T2，T5，T10，T11，T15和T17，若取值为000，则可以确定目标TCI状态为T0，若取值为001，则确定目标TCI状态为T2，依次类推。The network equipment can determine the network configuration through the 3-bit indication field in the Downlink Control Information (DCI) combined with the activated TCI status indicated by the Media Access Control Control Element (MAC CE) The TCI state, specifically, may have a corresponding relationship between the value of the 3-bit indication field in the DCI and the order of the activated TCI state, and the TCI state of the order corresponding to the value in the activated TCI state may be determined as the network The configured target TCI state. For example, if the activated TCI state includes T0, T2, T5, T10, T11, T15 and T17, if the value is 000, the target TCI state can be determined to be T0, and if the value is 001, the target TCI state is determined to be T2 ,And so on.

其中，在QCL信息1和QCL信息2中，至少一个QCL信息的QCL类型为QCL TypeA，QCL TypeB，QCL TypeC中的一个，如果配置另一个QCL信息，则该QCL信息的QCL类型为QCL TypeD。Among them, in QCL information 1 and QCL information 2, the QCL type of at least one QCL information is one of QCL TypeA, QCL TypeB, and QCL TypeC. If another QCL information is configured, the QCL type of the QCL information is QCL TypeD.
其中，不同QCL类型配置的定义如下：Among them, the definition of different QCL type configurations is as follows:

如果网络设备通过TCI状态配置目标下行信道的QCL参考信号为参考同步信号块(synchronizing signal/PBCH block，SS/PBCH block)或参考信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)资源，且QCL类型配置为QCL-TypeA，QCL-TypeB或QCL-TypeC，则终端设备可以假设所述目标下行信道与所述参考SSB或参考CSI-RS资源的目标大尺度参数是相同的，从而采用相同的相应接收参数进行接收，所述目标大尺度参数可以通过QCL类型配置来确定。类似地，如果网络设备通过TCI状态配置目标下行信道的QCL参考信号为参考SSB或参考CSI-RS资源，且QCL类型配置为QCL-TypeD，则终端设备可以采用与接收所述参考SSB或参考CSI-RS资源相同的接收波束(即Spatial Rx parameter)来接收所述目标下行信道。通常来说，目标下行信道与其参考SSB或参考CSI-RS资源在网络设备侧是由同一个TRP，同一个panel或者相同的波束来发送的。如果两个下行信号或下行信道的传输TRP或传输panel或发送波束不同，可以配置不同的TCI状态。If the network device configures the QCL reference signal of the target downlink channel through the TCI state as a reference synchronization signal block (synchronizing signal/PBCH block, SS/PBCH block) or a reference channel state information reference signal (Channel State Information Reference Signal, CSI-RS) resource , And the QCL type is configured as QCL-TypeA, QCL-TypeB or QCL-TypeC, the terminal device can assume that the target downlink channel is the same as the target large-scale parameter of the reference SSB or reference CSI-RS resource, so as to adopt The same corresponding receiving parameters are received, and the target large-scale parameters can be determined through QCL type configuration. Similarly, if the network device configures the QCL reference signal of the target downlink channel as a reference SSB or reference CSI-RS resource through the TCI state, and the QCL type is configured as QCL-TypeD, the terminal device can use and receive the reference SSB or reference CSI. -Receive beams (ie Spatial Rx parameter) with the same RS resources to receive the target downlink channel. Generally speaking, the target downlink channel and its reference SSB or reference CSI-RS resource are transmitted by the same TRP, the same panel or the same beam on the network device side. If the transmission TRP or transmission panel or transmission beam of the two downlink signals or downlink channels are different, different TCI states can be configured.
在本申请实施例中，DCI中可以包括第一指示域(或称TCI状态指示域)，该第一指示域可以用于指示K个TCI值，其中，K为正整数，例如，所述第一指示域可以为3比特，则所述第一指示域可以用于指示000～111，即8个TCI值。In the embodiment of the present application, the DCI may include a first indication field (or TCI status indication field), and the first indication field may be used to indicate K TCI values, where K is a positive integer, for example, the first indication field An indicator field can be 3 bits, and the first indicator field can be used to indicate 000-111, that is, 8 TCI values.

The specific number of TCI status IDs indicated by each TCI value and the indicated TCI status ID can be determined by the network device.
应理解，在本申请实施例中，所述TCI值也可以称为编码点(codepoint)值，则DCI中的第一指示域的取值可以称为TCI值或codepoint值，其可以指示一个或多个TCI状态ID。It should be understood that in the embodiment of the present application, the TCI value may also be referred to as a codepoint value, and the value of the first indicator field in the DCI may be referred to as a TCI value or a codepoint value, which may indicate one or Multiple TCI status IDs.
在本申请实施例中，终端设备可以接收网络设备发送的MAC CE，所述MAC CE中包括第一比特位图(bitmap)和TCI状态指示信息，所述第一比特位图(bitmap)可以用于确定所述K个TCI值中的每个TCI值指示的TCI状态ID的个数，所述TCI状态指示信息可以用于确定所述K个TCI值中的每个TCI值所指示的至少一个TCI状态ID，从而在终端设备接收到下行控制信息(Downlink Control Information，DCI)时，可以获知该DCI中的TCI值，进一步可以根据该MAC CE确定该TCI值所指示的至少一个TCI状态ID。In this embodiment of the application, the terminal device may receive the MAC CE sent by the network device, and the MAC CE includes a first bitmap (bitmap) and TCI status indication information, and the first bitmap (bitmap) may be used For determining the number of TCI status IDs indicated by each TCI value in the K TCI values, the TCI status indication information may be used to determine at least one of the K TCI values indicated by each TCI value TCI state ID, so that when the terminal device receives Downlink Control Information (DCI), it can learn the TCI value in the DCI, and further can determine at least one TCI state ID indicated by the TCI value according to the MAC CE.
作为一个示例，所述第一比特位图可以包括K组比特，每组比特可以对应一个TCI值，所述第一比特位图中的每组比特用于确定对应的TCI值所指示的TCI状态ID的个数，所述每组比特所包括的比特数可以根据TCI值所指示的TCI状态ID的最大个数确定。As an example, the first bitmap may include K groups of bits, each group of bits may correspond to a TCI value, and each group of bits in the first bitmap is used to determine the TCI status indicated by the corresponding TCI value The number of IDs, the number of bits included in each group of bits can be determined according to the maximum number of TCI state IDs indicated by the TCI value.
例如，若一个TCI值最多对应2个TCI状态ID，可以每组比特可以为1比特，用于指示所述每个TCI值所指示的TCI状态ID的个数为一个或两个。For example, if one TCI value corresponds to at most two TCI status IDs, each group of bits can be 1 bit, which is used to indicate that the number of TCI status IDs indicated by each TCI value is one or two.
又例如，若一个TCI值最多对应3个TCI状态ID，则可以每组比特可以为2比特，用于指示所述每个TCI值所指示的TCI状态的个数为一个，两个或三个，作为示例而非限定，可以设置00指示一个TCI状态，01指示两个TCI状态，10和11指示三个TCI状态，或者也可以采用其他指示方式。以下，以一个TCI值最多指示2个TCI状态为例进行说明，当一个TCI值指示更多个TCI状态时，可以采用类似的方式指示，为了简洁，这里不再赘述。For another example, if one TCI value corresponds to at most 3 TCI state IDs, each group of bits may be 2 bits, which are used to indicate that the number of TCI states indicated by each TCI value is one, two or three. As an example and not a limitation, 00 can be set to indicate one TCI state, 01 to indicate two TCI states, 10 and 11 to indicate three TCI states, or other indication methods can also be used. In the following, a TCI value indicating at most two TCI states is taken as an example for description. When one TCI value indicates more TCI states, it can be indicated in a similar manner. For brevity, details are not described here.
以下结合具体实施例，说明所述第一比特位图和TCI状态指示信息的实现方式。The following describes the implementation of the first bitmap and TCI status indication information in conjunction with specific embodiments.
实施例1：Example 1:
所述第一比特位图中的每个比特位对应一个TCI值，每个比特位可以用于指示对应的TCI值指示一个TCI状态ID或两个TCI状态ID，或者说，每个比特位可以用于指示对应的TCI值是否指示第二个TCI状态ID，若指示第二个TCI状态ID，则表示该TCI值一共指示两个TCI状态ID，或不指示第二个TCI状态ID，则表示该TCI值一共指示一个TCI状态ID。Each bit in the first bitmap corresponds to a TCI value, and each bit can be used to indicate that the corresponding TCI value indicates one TCI status ID or two TCI status IDs, or in other words, each bit can be Used to indicate whether the corresponding TCI value indicates the second TCI status ID, if it indicates the second TCI status ID, it means that the TCI value indicates two TCI status IDs in total, or does not indicate the second TCI status ID, it means The TCI value indicates a TCI status ID in total.
例如，所述第一比特位图中的比特位B i取第一值(例如，0)用于指示对应的TCI值不指示第二个TCI状态ID，所述比特位B i取第二值(例如，1)用于指示对应的TCI值指示第二个TCI状态ID，其中，所述i为0,1,……,K-1，其中，K为所述第一比特位图所占的比特位数，或者说，TCI值的总个数。 For example, the bit B i in the first bitmap takes a first value (for example, 0) to indicate that the corresponding TCI value does not indicate the second TCI state ID, and the bit B i takes the second value (For example, 1) is used to indicate that the corresponding TCI value indicates the second TCI state ID, where the i is 0, 1, ..., K-1, where K is the first bitmap The number of bits, or the total number of TCI values.
在该实施例1中，所述TCI状态指示信息包括第二比特位图，所述第二比特位图中的每一个比特位对应一个TCI状态ID，所述第二比特位图中的每一个比特位用于指示对应的TCI状态ID为激活状态或去激活状态。其中，所述第二比特位图可以用于确定每一个TCI值所对应的第一个TCI状态ID，确定第一个TCI状态ID的方式可以与现有方式相同。In this embodiment 1, the TCI status indication information includes a second bitmap, and each bit in the second bitmap corresponds to a TCI status ID, and each bit in the second bitmap The bit is used to indicate that the corresponding TCI state ID is in the activated state or in the deactivated state. The second bitmap may be used to determine the first TCI state ID corresponding to each TCI value, and the method for determining the first TCI state ID may be the same as the existing method.
作为一个示例，所述第二比特位图中的比特位T i取第三值(例如，1)用于指示对应的TCI状态ID为激活状态，所述第二比特位图中的比特位T i取第四值(例如，0)用于指示对应的TCI状态ID为去激活状态，其中，所述i为0,1,……,M-1，其中，M为所述第二比特位图所占的比特位数，或者说，TCI状态ID的总个数。例如，M为128，则该第二比特位图可以占128个比特，每一个比特用于指示对应的一个TCI状态ID是否激活。 As an example, the bit T i in the second bitmap takes a third value (for example, 1) to indicate that the corresponding TCI state ID is in the active state, and the bit T i in the second bitmap The fourth value of i (for example, 0) is used to indicate that the corresponding TCI state ID is in the deactivated state, where the i is 0, 1, ..., M-1, where M is the second bit The number of bits occupied by the graph, or the total number of TCI state IDs. For example, if M is 128, the second bitmap may occupy 128 bits, and each bit is used to indicate whether a corresponding TCI state ID is activated.
作为一个示例，所述第二比特位图所指示的激活的TCI状态ID的个数小于一定阈值，例如8，即M个TCI状态ID中最多有8个激活的TCI状态ID。As an example, the number of activated TCI state IDs indicated by the second bitmap is less than a certain threshold, such as 8, that is, there are at most 8 activated TCI state IDs among the M TCI state IDs.
可选地，所述第二比特位图位于所述第一比特位图之前。Optionally, the second bitmap is located before the first bitmap.
若根据所述第一比特位图确定K个TCI值中存在至少一个TCI值指示第二个TCI状态ID，则进一步地，所述TCI状态指示信息还包括所述至少一个TCI值中的每个TCI值所指示的第二个TCI状态ID。If it is determined according to the first bitmap that at least one TCI value in the K TCI values indicates the second TCI state ID, further, the TCI state indication information further includes each of the at least one TCI value The second TCI status ID indicated by the TCI value.
可选地，所述至少一个TCI值指示的第二个TCI状态ID按照所述至少一个TCI值的大小顺序排列，因此，终端设备可以按照TCI值的大小确定所述至少一个TCI值中的每个TCI值所指示的第二个TCI状态ID。Optionally, the second TCI state ID indicated by the at least one TCI value is arranged in the order of the size of the at least one TCI value. Therefore, the terminal device may determine each of the at least one TCI value according to the size of the TCI value. The second TCI status ID indicated by a TCI value.
可选地，所述至少一个TCI值指示的第二个TCI状态ID位于所述第一比特位图之后。Optionally, the second TCI state ID indicated by the at least one TCI value is located after the first bitmap.
以8个TCI值为例，若TCI值000，TCI值010和TCI值100指示第二个TCI状态ID，其他TCI值不指示第二个TCI状态ID，则所述TCI值000，TCI值010和TCI值100分别指示的第二个TCI状态ID可以按照000，010和100的顺序排列。即所述第一比特位图之后的第一个TCI状态ID为TCI值000对应的第二个TCI状态ID，所述第一比特位图之后的第二个TCI状态ID为TCI值010对应的第二个TCI状态ID，所述第一比特位图之后的第三个TCI状态ID为TCI值100对应的第二个TCI状态ID。Taking 8 TCI values as an example, if the TCI value is 000, the TCI value is 010, and the TCI value is 100 indicates the second TCI status ID, and other TCI values do not indicate the second TCI status ID, then the TCI value is 000 and the TCI value is 010 The second TCI status ID indicated by the TCI value of 100 can be arranged in the order of 000, 010 and 100. That is, the first TCI state ID after the first bitmap is the second TCI state ID corresponding to the TCI value of 000, and the second TCI state ID after the first bitmap is corresponding to the TCI value 010 The second TCI state ID, the third TCI state ID after the first bitmap is the second TCI state ID corresponding to the TCI value of 100.
因此，在该实施例1中，终端设备接收到DCI后，可以根据DCI确定一个TCI值，然后可以根据MAC CE中的第二比特位图确定激活的TCI状态ID，然后根据该TCI值和激活的TCI状态ID的顺序的对应关系，确定所述TCI值指示的第一个TCI状态ID，例如，若TCI值为000，可以确定第一个激活的TCI状态ID为所述TCI值指示的第一个TCI状态ID，或者若TCI值为001，可以确定第二个激活的TCI状态ID为所述TCI值指示的第一个TCI状态ID，依次类推。Therefore, in this embodiment 1, after receiving the DCI, the terminal device can determine a TCI value according to the DCI, and then can determine the activated TCI state ID according to the second bitmap in the MAC CE, and then according to the TCI value and activation The corresponding relationship of the sequence of the TCI status IDs of the TCI is determined, and the first TCI status ID indicated by the TCI value is determined. For example, if the TCI value is 000, it can be determined that the first activated TCI status ID is the first TCI status ID indicated by the TCI value. A TCI status ID, or if the TCI value is 001, it can be determined that the second activated TCI status ID is the first TCI status ID indicated by the TCI value, and so on.
进一步地，所述终端设备可以根据所述第一比特位图确定所述TCI值是否指示第二个TCI状态ID，若指示第二个TCI状态ID，所述终端设备可以根据所述TCI值的大小，结合所述TCI值在指示第二个TCI状态ID的TCI值中的大小顺序，在所述TCI状态指示信息所指示的TCI状态ID中确定所述TCI值指示的第二个TCI状态ID。Further, the terminal device may determine whether the TCI value indicates a second TCI state ID according to the first bitmap, and if the second TCI state ID is indicated, the terminal device may determine according to the TCI value Size, combined with the size order of the TCI value in the TCI value indicating the second TCI state ID, and determining the second TCI state ID indicated by the TCI value in the TCI state ID indicated by the TCI state indication information .
接着上个示例，若DCI中的TCI值为010，则所述终端设备可以确定所述第一比特位图之后的第二个TCI状态ID为所述TCI值010所指示的第二个TCI状态ID。Following the previous example, if the TCI value in the DCI is 010, the terminal device can determine that the second TCI state ID after the first bitmap is the second TCI state indicated by the TCI value 010 ID.
可选地，在一些实施例中，所述MAC CE还可以包括服务小区标识(serving cell ID)和带宽部分(Band Width Part，BWP)ID。Optionally, in some embodiments, the MAC CE may also include a serving cell ID (serving cell ID) and a bandwidth part (Band Width Part, BWP) ID.
作为一个示例，所述第二比特位图可以位于所述serving cell ID和BWP ID之后。As an example, the second bitmap may be located after the serving cell ID and BWP ID.
图3示出了根据本申请实施例1的MAC CE的一种示意性格式图。FIG. 3 shows a schematic format diagram of MAC CE according to Embodiment 1 of the present application.
该MAC CE可以包括如下信息：The MAC CE may include the following information:
1、serving cell ID和BWP ID，占MAC CE中的字节1(Oct1)；1. The serving cell ID and BWP ID occupy byte 1 (Oct1) in the MAC CE;
2、第二bitmap，即T 0～T (N-2)*8+7，为(N-1)*8个TCI状态ID的bitmap，分别用于指示(N-1)*8个TCI状态ID中的每个TCI状态ID是否激活，若TCI状态ID的总个数为128，即N为17，128个比特的bitmap占MAC CE的16个字节，即字节2(Oct 2)-字节17(Oct 17)； 2. The second bitmap, namely T 0 ～T (N-2)*8+7 , is a bitmap of (N-1)*8 TCI status IDs, used to indicate (N-1)*8 TCI statuses respectively Whether each TCI status ID in the ID is activated, if the total number of TCI status IDs is 128, that is, N is 17, the 128-bit bitmap occupies 16 bytes of MAC CE, that is, byte 2 (Oct 2)- Byte 17 (Oct 17);
3、第一bitmap，位于所述第二bitmap之后，第一bitmap的长度可以根据TCI值的个数确定，若有8个TCI值，则第一bitmap可以为8比特(B 0～B 7)，分别用于指示每个TCI值是否指示第二个TCI状态ID。或者，若TCI值不足8个，为了字节对齐，可以在第一bitmap前添加预留比特； 3. The first bitmap is located after the second bitmap. The length of the first bitmap can be determined according to the number of TCI values. If there are 8 TCI values, the first bitmap can be 8 bits (B 0 ～B 7 ) , Respectively used to indicate whether each TCI value indicates the second TCI status ID. Or, if the TCI value is less than 8, for byte alignment, reserved bits can be added before the first bitmap;
4、TCI状态指示信息，若根据第一bitmap确定存在至少一个TCI值指示第二个TCI状态ID，则所述MAC CE还包括所述至少一个TCI值分别指示的第二个TCI状态ID，其中，所述至少一个TCI值指示的第二个TCI状态ID按照所述至少一个TCI值的大小顺序排列。例如，可以将所述至少一个TCI值指示的第二个TCI状态ID按照所述至少一个TCI值由小到大的顺序排列。4. TCI status indication information. If it is determined according to the first bitmap that there is at least one TCI value indicating the second TCI status ID, the MAC CE also includes the second TCI status ID respectively indicated by the at least one TCI value, where , The second TCI state ID indicated by the at least one TCI value is arranged in order of magnitude of the at least one TCI value. For example, the second TCI state ID indicated by the at least one TCI value may be arranged in ascending order of the at least one TCI value.
作为一个示例，所述至少一个TCI值所指示的TCI状态ID可以紧邻设置，如图3所示。As an example, the TCI state ID indicated by the at least one TCI value may be set immediately, as shown in FIG. 3.
作为另一示例，为了字节对齐，可以在TCI状态ID前设置预留比特，例如，若TCI状态ID为7个字节，可以在TCI状态ID前设置1个比特的预留比特，例如，图4所示，或者也可以在TCI状态ID后设置预留比特，本申请对此不作限定。As another example, for byte alignment, a reserved bit can be set before the TCI state ID. For example, if the TCI state ID is 7 bytes, a 1-bit reserved bit can be set before the TCI state ID, for example, As shown in FIG. 4, or the reserved bit may be set after the TCI state ID, which is not limited in this application.
终端设备可以接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)，确定该PDCCH的DCI中的第一指示域所指示的TCI值，然后根据该TCI值结合所述MAC CE中的第二bitmap确定所述TCI值指示的第一个TCI状态ID，具体实现参考前文的相关描述。The terminal device may receive the Physical Downlink Control Channel (PDCCH), determine the TCI value indicated by the first indicator field in the DCI of the PDCCH, and then determine the TCI value according to the TCI value in combination with the second bitmap in the MAC CE For the first TCI status ID indicated by the TCI value, for specific implementation, refer to the relevant description above.
进一步地，所述终端设备可以根据所述第一bitmap，确定所述TCI值是否指示第二个TCI状态ID，若指示第二个TCI状态ID，所述终端设备可以根据所述TCI值的大小，在所述第一bitmap后所指示的TCI状态ID中确定所述TCI值指示的第二个TCI状态ID，具体实现参考前文的相关描述。Further, the terminal device may determine whether the TCI value indicates a second TCI state ID according to the first bitmap, and if the second TCI state ID is indicated, the terminal device may determine whether the TCI value is , The second TCI state ID indicated by the TCI value is determined in the TCI state ID indicated after the first bitmap, and the specific implementation refers to the relevant description above.
以第一bitmap为8比特，TCI状态ID为7个字节，第二bitmap为16个字节为例，说明在TCI值指示不同个数的TCI状态ID时，MAC CE所占的比特数(不考虑服务小区ID和BWP ID所占字节)的大小。Taking the first bitmap as 8 bits, the TCI status ID as 7 bytes, and the second bitmap as 16 bytes as an example, to illustrate the number of bits occupied by the MAC CE when the TCI value indicates different numbers of TCI status IDs ( The size of the serving cell ID and the bytes occupied by the BWP ID are not considered.
情况1：若所有的TCI值都只指示一个TCI状态ID，则MAC CE可以占16个字节(第一bitmap)+1个字节(第二bitmap)，即17个字节。Case 1: If all TCI values only indicate one TCI status ID, the MAC CE can occupy 16 bytes (first bitmap) + 1 byte (second bitmap), that is, 17 bytes.
情况2：若所有的TCI值都指示两个TCI状态ID，基于图3所示的MAC CE格式，则MAC CE可以占16个字节(第一bitmap)+1个字节(第二bitmap)+8*7比特，即24个字节；Case 2: If all TCI values indicate two TCI status IDs, based on the MAC CE format shown in Figure 3, MAC CE can occupy 16 bytes (first bitmap) + 1 byte (second bitmap) +8*7 bits, that is, 24 bytes;
情况3：若所有的TCI值都指示两个TCI状态ID，基于图4所示的MAC CE格式，则MAC CE可以占16个字节(第一bitmap)+1个字节(第二bitmap)+8*8比特(7比特TCI状态ID+1个预留比特)，即25个字节。Case 3: If all TCI values indicate two TCI status IDs, based on the MAC CE format shown in Figure 4, the MAC CE can occupy 16 bytes (first bitmap) + 1 byte (second bitmap) +8*8 bits (7 bits TCI status ID + 1 reserved bit), that is, 25 bytes.
因此，基于实施例1的MAC CE的格式，MAC CE所占的字节数范围为17至25个字节。Therefore, based on the MAC CE format of Embodiment 1, the number of bytes occupied by the MAC CE ranges from 17 to 25 bytes.
实施例2：Example 2:
所述第一比特位图中的每个比特位对应一个TCI值，每个比特位可以用于指示对应的TCI值指示的TCI状态ID的个数，或者，每个比特位可以用于指示对应的TCI值是否指示第二个TCI状态ID。Each bit in the first bitmap corresponds to a TCI value, and each bit can be used to indicate the number of TCI status IDs indicated by the corresponding TCI value, or each bit can be used to indicate the corresponding Whether the TCI value indicates the second TCI status ID.
例如，所述第一比特位图中的比特位B i取第一值(例如，0)用于指示对应的TCI值指示两个TCI状态ID，所述比特位B i取第二值(例如，1)用于指示对应的TCI值指示一个TCI状态ID，其中，所述i为0,1,……,K-1，其中，K为所述第一比特位图所占的比特位数，或者说，TCI值的总个数。 For example, the bit B i in the first bitmap takes a first value (for example, 0) to indicate that the corresponding TCI value indicates two TCI state IDs, and the bit B i takes a second value (for example, , 1) is used to indicate that the corresponding TCI value indicates a TCI state ID, where the i is 0, 1,..., K-1, where K is the number of bits occupied by the first bitmap , Or the total number of TCI values.
所述TCI状态指示信息可以用于指示每个TCI值指示的TCI状态ID。The TCI status indication information may be used to indicate the TCI status ID indicated by each TCI value.
作为一个示例，所述TCI状态指示信息可以位于所述第一比特位图之后。As an example, the TCI status indication information may be located after the first bitmap.
作为一个示例，所述每个TCI值指示的TCI状态ID按照所述每个TCI值的大小顺序排列，例如，可以按照TCI值由小到大的顺序排列所述每个TCI值指示的TCI状态ID，这样，所述终端设备可以根据DCI中的TCI值的大小确定所述TCI值指示的TCI状态ID。As an example, the TCI status ID indicated by each TCI value is arranged in the order of the size of each TCI value, for example, the TCI status indicated by each TCI value may be arranged in the order of TCI value from small to large ID. In this way, the terminal device can determine the TCI state ID indicated by the TCI value according to the size of the TCI value in the DCI.
在一些实施例中，若所述TCI状态ID的大小不足整字节，可以填充预留比特，例如，在TCI状态ID之前填充预留比特以使TCI状态ID加预留比特的大小足够整字节，例如，若TCI状态ID占7个比特，可以在这7个比特前设置一个预留比特，如图5所示。In some embodiments, if the size of the TCI state ID is less than a whole byte, reserved bits may be filled, for example, reserved bits are filled before the TCI state ID so that the size of the TCI state ID plus the reserved bits is enough for a whole word For example, if the TCI status ID occupies 7 bits, a reserved bit can be set before these 7 bits, as shown in Figure 5.
在其他实施例中，TCI状态ID之间紧邻设置，即TCI状态ID之间不设置预留比特，这样，所述TCI状态指示信息可以为TCI状态ID实际所占的字节大小，如图6所示。In other embodiments, the TCI status IDs are set next to each other, that is, no reserved bits are set between the TCI status IDs. In this way, the TCI status indication information can be the actual byte size of the TCI status ID, as shown in Figure 6. Shown.
因此，在该实施例2中，终端设备接收到DCI后，可以根据DCI确定一个TCI值，进一步可以根据MAC CE中的第一比特位图确定所述TCI值指示的TCI状态ID的个数，然后可以根据所述TCI值的大小，在所述TCI状态指示信息所指示的TCI状态ID中确定所述TCI值所指示的TCI状态ID。Therefore, in Embodiment 2, after receiving the DCI, the terminal device can determine a TCI value according to the DCI, and can further determine the number of TCI state IDs indicated by the TCI value according to the first bitmap in the MAC CE. Then, the TCI state ID indicated by the TCI value may be determined from the TCI state ID indicated by the TCI state indication information according to the size of the TCI value.
图5和图6分别为根据实施例2的MAC CE的两种示意性格式图。图5和图6的区别在于，图5所示的格式中TCI状态ID之间设置有预留比特，图6所示的格式中TCI状态ID紧邻。Figures 5 and 6 are respectively two schematic format diagrams of MAC CE according to Embodiment 2. The difference between FIG. 5 and FIG. 6 is that reserved bits are set between the TCI state IDs in the format shown in FIG. 5, and the TCI state IDs are adjacent to each other in the format shown in FIG.
如图5和图6所示，该MAC CE可以包括如下信息：As shown in Figure 5 and Figure 6, the MAC CE may include the following information:
1、serving cell ID和BWP ID，占MAC CE中的字节1(Oct1)；1. The serving cell ID and BWP ID occupy byte 1 (Oct1) in the MAC CE;
2、第一bitmap，第一比特map的长度可以根据TCI值的个数确定，若DCI中的TCI值可以有8种，则第一bitmap可以为8比特(B 0～B 7)，分别用于指示每个TCI值指示的TCI状态ID的个数。或者，若TCI值不足8个，为了字节对齐，可以在第一bitmap前添加预留比特； 2. The first bitmap, the length of the first bit map can be determined according to the number of TCI values. If there are 8 TCI values in the DCI, the first bitmap can be 8 bits (B 0 ～B 7 ), respectively It indicates the number of TCI status IDs indicated by each TCI value. Or, if the TCI value is less than 8, for byte alignment, reserved bits can be added before the first bitmap;
3、TCI状态指示信息，包括每个TCI值指示的TCI状态ID。每个TCI值指示的TCI状态ID按照所述每个TCI值的大小顺序排列。例如，可以将所述每个TCI值指示的TCI状态ID按照TCI值由小到大的顺序排列。3. TCI status indication information, including the TCI status ID indicated by each TCI value. The TCI status ID indicated by each TCI value is arranged in the order of the magnitude of each TCI value. For example, the TCI state ID indicated by each TCI value may be arranged in the order of TCI value from small to large.
进一步地，终端设备可以接收PDCCH，根据该PDCCH的DCI包括第一指示域所指示的TCI值，以及所述第一bitmap，可以确定所述TCI值指示的TCI状态ID的个数，然后可以根据所述第一bitmap以及所述TCI值的大小，在所述TCI状态指示信息所指示的TCI状态ID中确定所述TCI值指示的TCI状态ID。Further, the terminal device may receive the PDCCH, and according to the DCI of the PDCCH including the TCI value indicated by the first indication field, and the first bitmap, the number of TCI status IDs indicated by the TCI value may be determined, and then the number of TCI status IDs indicated by the TCI value may be determined according to The first bitmap and the size of the TCI value determine the TCI status ID indicated by the TCI value in the TCI status ID indicated by the TCI status indication information.
以8个TCI值000～111为例，网络设备配置TCI值和TCI状态ID具有如表1所示的对应关系，则该网络设备可以通过MAC CE中的第一bitmap和TCI状态指示信息指示该对应关系，此情况下，所述MAC CE可以具体如图7所示。Taking 8 TCI values 000～111 as an example, the network device configuration TCI value and TCI status ID have a corresponding relationship as shown in Table 1, then the network device can indicate this through the first bitmap and TCI status indication information in the MAC CE Correspondence, in this case, the MAC CE may be specifically as shown in FIG. 7.
表1Table 1
TCI值TCI value TCI状态ID TCI status ID
000000 22
001001 4，54, 5
010010 7，97, 9
011011 10，1110, 11
100100 1515
101101 25，2925, 29
110110 4040
111111 50，6050, 60
若DCI中的TCI值为101，则该终端设备可以确定B 5为1，即TCI值101指示两个TCI状态ID，根据第一bitmap也可以确定其他TCI值指示的TCI状态ID的个数，进一步所述终端设备可以在所述第一bitmap后的TCI状态指示信息中查找所述TCI值101所指示的TCI状态ID，根据所述第一bitmap可以确定TCI状态指示信息中的第9个和第10个TCI状态ID对应TCI值101，即字节11和字节12中包括TCI值101指示的TCI状态ID，即25和29。 If the value of TCI in the DCI 101, the terminal device may determine B 5 is 1, i.e., two TCI TCI value of 101 indicates a state ID, may determine the number of other TCI TCI state ID indicates a value according to a first bitmap, Further, the terminal device can search for the TCI status ID indicated by the TCI value 101 in the TCI status indication information after the first bitmap, and can determine the ninth and the TCI status indication information according to the first bitmap. The tenth TCI status ID corresponds to the TCI value 101, that is, the TCI status ID indicated by the TCI value 101 is included in byte 11 and byte 12, namely 25 and 29.
以第一bitmap为8比特，TCI状态ID为7个字节为例，说明在TCI值指示不同个数的TCI状态ID时，MAC CE所占的比特数(不考虑服务小区ID和BWP ID所占字节)。Taking the first bitmap of 8 bits and the TCI status ID of 7 bytes as an example, it is explained that when the TCI value indicates different numbers of TCI status IDs, the number of bits occupied by the MAC CE (not considering the serving cell ID and BWP ID) Occupies bytes).
情况1：若每个TCI值都只指示一个TCI状态ID，基于图5所示的MACCE格式，则MAC CE可以占1字节(第一bitmap)+8*1个字节(7bit的TCI ID+1个预留比特)，即9个字节。Case 1: If each TCI value only indicates one TCI status ID, based on the MACCE format shown in Figure 5, MAC CE can occupy 1 byte (first bitmap) + 8*1 bytes (7bit TCI ID +1 reserved bit), that is, 9 bytes.
情况2：若每个TCI值都指示两个TCI状态ID，基于图5所示的MAC CE格式，则MAC CE可以占1字节(第一bitmap)+8*2个字节，即17个字节。Case 2: If each TCI value indicates two TCI status IDs, based on the MAC CE format shown in Figure 5, MAC CE can occupy 1 byte (first bitmap) + 8*2 bytes, that is, 17 byte.
则，基于图5所示的MAC CE格式，MAC CE所占的字节数范围为9至17个字节。Then, based on the MAC CE format shown in Figure 5, the number of bytes occupied by the MAC CE ranges from 9 to 17 bytes.
情况3：若每个TCI值都只指示一个TCI状态ID，基于图6所示的MACCE格式，则MAC CE可以占1字节(第一bitmap)+8*7个比特，即8个字节。Case 3: If each TCI value indicates only one TCI status ID, based on the MACCE format shown in Figure 6, MAC CE can occupy 1 byte (first bitmap) + 8*7 bits, that is, 8 bytes .
情况4：若每个TCI值都指示两个个TCI状态ID，基于图6所示的MACCE格式，则MAC CE 可以占1字节(第一bitmap)+8*14个比特，即15个字节。Case 4: If each TCI value indicates two TCI status IDs, based on the MACCE format shown in Figure 6, MAC CE can occupy 1 byte (first bitmap) + 8*14 bits, that is 15 words Section.
则，基于图6所示的MAC CE格式，MAC CE所占的字节数范围为8至15个字节。Then, based on the MAC CE format shown in Figure 6, the number of bytes occupied by the MAC CE ranges from 8 to 15 bytes.
因此，相对于图5所示的MAC CE格式，采用图6所示的MAC CE格式，可省一个字节。Therefore, compared with the MAC CE format shown in FIG. 5, using the MAC CE format shown in FIG. 6 can save one byte.
图8是根据本申请另一实施例的无线通信的方法的示意性框图，如图8所示，所述方法300包括至少部分如下内容：FIG. 8 is a schematic block diagram of a wireless communication method according to another embodiment of the present application. As shown in FIG. 8, the method 300 includes at least part of the following content:
S310，终端设备接收网络设备发送的媒体接入控制MAC控制元素CE，所述MAC CE包括K组传输配置指示TCI状态标识ID和所述K组TCI状态ID分别对应的K组指示信息；S310: The terminal device receives a media access control MAC control element CE sent by the network device, where the MAC CE includes K group transmission configuration indication TCI status identifier ID and K group indication information corresponding to the K group TCI status ID respectively;
其中，所述K组TCI状态ID中的每组TCI状态ID包括相邻的两个TCI状态ID，所述每组TCI状态ID对应下行控制信息DCI中的一个TCI值，所述K组指示信息中的一组指示信息用于指示对应的一组TCI状态ID是否激活，所述K为所述TCI值的总个数。Wherein, each group of TCI status IDs in the K groups of TCI status IDs includes two adjacent TCI status IDs, each group of TCI status IDs corresponds to a TCI value in the downlink control information DCI, and the K group indication information A group of indication information in is used to indicate whether a corresponding group of TCI status ID is activated, and the K is the total number of the TCI values.
为便于区分和说明，将该实施例记为实施例3，在该实施例3中，一个TCI值对应一组TCI状态标识ID和一组指示信息，每组TCI状态标识ID可以用于指示对应的TCI值对应的多个TCI状态ID，例如，2个TCI状态ID，每组指示信息用于指示对应的TCI值所对应的多个TCI状态ID中激活的至少一个TCI状态ID。For the convenience of distinguishing and explaining, this embodiment is marked as embodiment 3. In this embodiment 3, a TCI value corresponds to a group of TCI status ID and a group of indication information, and each group of TCI status ID can be used to indicate the corresponding TCI value corresponding to multiple TCI state IDs, for example, two TCI state IDs, each group of indication information is used to indicate at least one activated TCI state ID among the multiple TCI state IDs corresponding to the corresponding TCI value.
应理解，在该实施例3中，每个TCI值对应的多个TCI状态ID并不一定是该TCI值实际指示的TCI状态ID，需要进一步结合所述TCI值对应的指示信息确定所述TCI值对应的多个TCI状态ID中激活的TCI状态ID。It should be understood that in Embodiment 3, the multiple TCI status IDs corresponding to each TCI value are not necessarily the TCI status IDs actually indicated by the TCI value, and the TCI needs to be further combined with the indication information corresponding to the TCI value to determine the TCI. The active TCI state ID among the multiple TCI state IDs corresponding to the value.
在该实施例3中，每个TCI值指示的一组TCI状态ID所占的比特数相同，因此，每组TCI状态ID所占的比特数的大小根据TCI值指示的TCI状态ID的最大个数确定。In this embodiment 3, the number of bits occupied by a group of TCI status IDs indicated by each TCI value is the same. Therefore, the number of bits occupied by each group of TCI status IDs is based on the maximum number of TCI status IDs indicated by the TCI value. The number is ok.
例如，若第一TCI值指示一个TCI状态ID，第二TCI值指示两个TCI状态ID，则每组TCI状态ID所占的比特数的大小最少能指示两个TCI状态ID；For example, if the first TCI value indicates one TCI state ID, and the second TCI value indicates two TCI state IDs, the size of the number of bits occupied by each group of TCI state IDs can indicate at least two TCI state IDs;
又例如，若第一TCI值指示一个TCI状态ID，第二TCI值指示两个TCI状态ID，第三TCI至指示三个TCI状态ID，则每组TCI状态ID所占的比特数的大小最少能指示三个TCI状态ID。For another example, if the first TCI value indicates one TCI state ID, the second TCI value indicates two TCI state IDs, and the third TCI to indicate three TCI state IDs, then the size of the number of bits occupied by each group of TCI state IDs is the smallest Can indicate three TCI status IDs.
以下，以每组TCI状态ID包括两个TCI状态ID为例进行说明，则对应的一组指示信息可以包括两个比特B 0和B 1，分别指示这两个TCI状态ID中的每个TCI状态ID是否激活。 In the following, each group of TCI status ID includes two TCI status IDs as an example for description, the corresponding group of indication information may include two bits B 0 and B 1 , indicating each of the two TCI status IDs. Whether the status ID is activated.
例如，所述比特B 0取第一值(例如1)用于指示对应的TCI状态ID激活，所述比特B 0取第二值(例如0)用于指示对应的TCI状态ID去激活；所述比特B 1取第一值(例如1)用于指示对应的TCI状态ID激活，所述比特B 1取第二值(例如0)用于指示对应的TCI状态ID去激活。 For example, the bit B 0 takes a first value (for example, 1) to indicate that the corresponding TCI state ID is activated, and the bit B 0 takes a second value (for example, 0) to indicate that the corresponding TCI state ID is deactivated; The bit B 1 takes a first value (for example, 1) to indicate that the corresponding TCI state ID is activated, and the bit B 1 takes a second value (for example, 0) to indicate that the corresponding TCI state ID is deactivated.
作为一个示例，所述比特B 0和比特B 1中至少有一个比特取所述第一值，即每个TCI值至少指示一个TCI状态ID。 As an example, at least one of the bit B 0 and the bit B 1 takes the first value, that is, each TCI value indicates at least one TCI state ID.
作为一个示例，每组指示信息中的两个比特中的每个比特位于所述每个比特对应的TCI状态ID之前。例如，若B 0用于指示TCI状态标识T 0是否激活，则该B 0可以位于T 0前。 As an example, each of the two bits in each group of indication information is located before the TCI state ID corresponding to each bit. For example, if B 0 is used to indicate whether the TCI status indicator T 0 is activated, then the B 0 may be located before T 0 .
作为一个示例，所述每组TCI状态ID按照对应的TCI值的大小顺序排列，例如，可以按照TCI值由小到大的顺序排列每个TCI值对应的两个TCI状态ID。As an example, each group of TCI state IDs are arranged in the order of their corresponding TCI values. For example, two TCI state IDs corresponding to each TCI value may be arranged in the order of TCI value from small to large.
例如，若所述第一TCI值小于所述第二TCI值，则所述第一TCI值对应的一组TCI状态ID中的两个TCI状态ID位于所述第二TCI值对应的一组TCI状态中的两个TCI状态ID之前。For example, if the first TCI value is less than the second TCI value, two TCI state IDs in a group of TCI state IDs corresponding to the first TCI value are located in a group of TCI state IDs corresponding to the second TCI value Before the two TCI state IDs in the state.
图9为根据实施例3的MAC CE的示意性格式图。FIG. 9 is a schematic format diagram of a MAC CE according to Embodiment 3.
以8个TCI值，每个TCI状态ID占7个比特，每个TCI状态ID对应的指示信息占1个比特为例，该MAC CE可以包括如下信息：Taking 8 TCI values, each TCI state ID occupies 7 bits, and the indication information corresponding to each TCI state ID occupies 1 bit as an example, the MAC CE may include the following information:
1、serving cell ID和BWP ID，占MAC CE中的字节1(Oct1)；1. The serving cell ID and BWP ID occupy byte 1 (Oct1) in the MAC CE;
2、8组TCI状态ID和8组指示信息；2. 8 groups of TCI status ID and 8 groups of indication information;
每组TCI状态ID包括两个TCI状态ID，每组指示信息包括比特B 0和B 1分别用于指示对应的TCI状态ID激活或去激活。 Each group of TCI status ID includes two TCI status IDs, and each group of indication information includes bits B 0 and B 1 respectively for indicating activation or deactivation of the corresponding TCI status ID.
这8个TCI值分别对应的两个TCI状态ID以及这两个TCI状态ID对应的两个指示信息按照所述每个TCI值的大小顺序排列。例如，按照TCI值由小到大的顺序排列。则serving cell ID和BWP ID之后的第一个字节和第二个字节包括TCI值000对应的两个TCI状态ID以及这两个TCI状态ID对应的两个指示信息，第三个字节和第四个字节包括TCI值001对应的两个TCI状态ID以及这两个TCI状态ID对应的两个指示信息，依次类推。The two TCI state IDs corresponding to the eight TCI values and the two indication information corresponding to the two TCI state IDs are arranged in the order of the size of each TCI value. For example, arrange them in ascending order of TCI value. Then the first byte and the second byte after serving cell ID and BWP ID include two TCI status IDs corresponding to TCI value 000 and two indication information corresponding to these two TCI status IDs, and the third byte And the fourth byte includes two TCI status IDs corresponding to the TCI value 001 and two indication information corresponding to the two TCI status IDs, and so on.
因此，在该实施例3中，终端设备接收到DCI后，可以根据DCI确定一个TCI值，进一步可以根据所述TCI值的大小，在所述K组TCI状态ID中确定所述TCI值所对应的一组TCI状态ID，进一步结合这一组TCI状态ID对应的一组指示信息确定这一组TCI状态ID中激活的TCI状态ID。Therefore, in this embodiment 3, after receiving the DCI, the terminal device can determine a TCI value according to the DCI, and further can determine the corresponding TCI value in the K groups of TCI state IDs according to the size of the TCI value A group of TCI status IDs, and a group of indication information corresponding to this group of TCI status IDs are further combined to determine the activated TCI status ID in this group of TCI status IDs.
例如，若TCI值为001，则终端设备可以在MAC CE中确定第四个和第五个字节中包括所述TCI值001对应的一组TCI状态ID和一组指示信息，然后可以根据这一组TCI状态ID和这一组指示信息，确定激活的TCI状态ID。For example, if the TCI value is 001, the terminal device can determine in the MAC CE that the fourth and fifth bytes include a group of TCI status IDs and a group of indication information corresponding to the TCI value 001, and then can use this A group of TCI status ID and this group of indication information determine the active TCI status ID.
对于表1所示的TCI值和TCI状态ID的对应关系，若采用图8所示的MAC CE格式，则MAC CE的内容可以如图10所示。For the correspondence between the TCI value and the TCI state ID shown in Table 1, if the MAC CE format shown in FIG. 8 is adopted, the content of the MAC CE may be as shown in FIG. 10.
若终端设备接收到的DCI中的TCI值为100，则终端设备可以查找该MAC CE中的第十个和第十一个字节，确定该TCI值100对应的两个TCI状态ID为15和20，进一步结合这两个TCI状态ID为15和20对应的指示信息，可以确定TCI状态ID15激活，TCI状态ID20去激活，则可以确定TCI值100所指示的目标TCI状态ID为TCI状态ID15。If the TCI value in the DCI received by the terminal device is 100, the terminal device can look up the tenth and eleventh bytes in the MAC CE, and determine that the two TCI state IDs corresponding to the TCI value of 100 are 15 and 20. Further combining the indication information corresponding to the two TCI status IDs 15 and 20, it can be determined that the TCI status ID15 is activated and the TCI status ID20 is deactivated, and it can be determined that the target TCI status ID indicated by the TCI value 100 is the TCI status ID15.
应理解，以上TCI值和TCI状态ID的对应关系仅为示例，也可以为其他对应关系，本申请实施例对此不作限定。It should be understood that the above corresponding relationship between the TCI value and the TCI state ID is only an example, and other corresponding relationships may also be used, which is not limited in the embodiment of the present application.
因此，在该实施例3中，若TCI状态ID为7个字节，对应的指示信息为1比特，则MAC CE所占的比特数(不考虑服务小区ID和BWP ID所占字节)固定为16个比特。Therefore, in this embodiment 3, if the TCI status ID is 7 bytes and the corresponding indication information is 1 bit, the number of bits occupied by the MAC CE (regardless of the bytes occupied by the serving cell ID and BWP ID) is fixed It is 16 bits.
在该实施例3的另一实现方式中，所述K组指示信息位于所述K组TCI状态ID之前，此情况下，所述K组指示信息可以为16个比特的bitmap，K组TCI状态ID为16个TCI状态ID，按照对应的TCI值的大小顺序排列，同一个TCI值对应的两个TCI状态紧邻设置，或也可以设置预留位，该16个比特的bitmap可以用于指示这16个TCI状态ID激活或去激活。终端设备可以根据DCI中的TCI值的大小，确定16个TCI状态ID中该TCI值对应的两个TCI状态ID，进一步结合16个比特中该TCI值对应的两个比特的取值，确定这两个TCI状态ID中激活的TCI状态ID。In another implementation manner of Embodiment 3, the K group indication information is located before the K group TCI status ID. In this case, the K group indication information may be a 16-bit bitmap, and the K group TCI status The ID is 16 TCI state IDs, arranged in the order of the corresponding TCI value. Two TCI states corresponding to the same TCI value are set next to each other, or reserved bits can be set. The 16-bit bitmap can be used to indicate this 16 TCI status IDs are activated or deactivated. The terminal device can determine the two TCI state IDs corresponding to the TCI value among the 16 TCI state IDs according to the size of the TCI value in the DCI, and further combine the values of the two bits corresponding to the TCI value among the 16 bits to determine this The active TCI state ID of the two TCI state IDs.
综合上述实施例1至实施例3可看出，图3和图4所示的MAC CE最少占16个字节，图6所示的MAC CE最多占15个字节，图9所述的MAC CE格式为固定的16个字节，图3和图5所示的MAC CE格式，由于设置了预留位，字节对齐，便于终端设备查找TCI状态ID的位置，因此，采用图6所示的MAC CE格式有利于降低信令开销。Combining the foregoing Embodiments 1 to 3, it can be seen that the MAC CE shown in Figure 3 and Figure 4 occupies at least 16 bytes, and the MAC CE shown in Figure 6 occupies a maximum of 15 bytes. The MAC described in Figure 9 The CE format is a fixed 16 bytes. The MAC CE format shown in Figure 3 and Figure 5, due to the set reserved bits and byte alignment, is convenient for terminal equipment to find the position of the TCI status ID. Therefore, the MAC CE format shown in Figure 6 is adopted. The MAC CE format helps reduce signaling overhead.
