Background

In a New Radio (NR) system, a network device may configure a transmission configuration indicator (Transmission Configuration Indication, TCI) state for a downlink signal or a downlink channel to indicate a quasicont-co-located (QCL) reference signal of the downlink signal or the downlink channel, so that a terminal device may receive the downlink signal or the downlink channel based on the QCL reference signal.

The network device may determine the TCI state configured by the network by combining the 3-bit indication field in the downlink control information (Downlink Control Information, DCI) with the activated TCI state indicated by the medium access control element (Media Access Control Control Element, MAC CE), specifically, may have a correspondence relationship according to the value of the 3-bit indication field in the DCI and the order of the activated TCI states, and may determine the TCI state in the order corresponding to the value in the activated TCI state as the target TCI state configured by the network. For example, if the activated TCI states include T0, T2, T5, T10, T11, T15, and T17, if the value is 000, the target TCI state may be determined to be T0, if the value is 001, the target TCI state may be determined to be T2, and so on.

Fig. 2 is a schematic flowchart of a method of wireless communication according to an embodiment of the present application.

S210, the terminal device receives a medium access control MAC control element CE sent by the network device, where the MAC CE includes a first bit bitmap and transmission configuration indication TCI status indication information, where each bit in the first bit bitmap corresponds to one TCI value in the downlink control information DCI, each bit is used to indicate the number of TCI status IDs indicated by the corresponding TCI value, and the TCI status indication information is used to determine at least one TCI status ID corresponding to the TCI value corresponding to each bit.

In an embodiment of the present application, a TCI state may include the following configuration:

1. a TCI status Identifier (ID) for identifying a TCI status;

2. Quasi co-located (QCL) information 1;

3. QCL information 2.

One QCL information may include the following information:

the QCL type configuration may be, for example, one of QCL type a (QCL type a), QCL type B (QCL type B), QCL type C (QCL type C) or QCL type D (QCL type D);

the QCL reference signal configuration may include, for example, a cell ID where the reference signal is located, a Bandwidth part (BWP) ID, and an identification of the reference signal (for example, may be a CSI-RS resource ID or an SSB index).

Wherein, in the QCL information 1 and the QCL information 2, the QCL type of at least one QCL information is one of QCL type a, QCL type b, and QCL type c, and if another QCL information is configured, the QCL type of the QCL information is QCL type d.

Wherein, the definition of different QCL type configurations is as follows:

1. QCL-TypeA: { Doppler shift (Doppler shift), doppler spread (Doppler spread), average delay (average delay), delay spread (delay spread) };

2、QCL-TypeB：{Doppler shift,Doppler spread}；

3、QCL-TypeC：{Doppler shift,average delay}；

4. QCL-TypeD: { spatial reception parameters (Spatial Rx parameter) }.

If the network device configures the QCL reference signal of the target downlink channel through the TCI state to be 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 to be QCL-TypeA, QCL-TypeB or QCL-TypeC, the terminal device may assume that the target downlink channel is the same as the target macro-scale parameter of the reference SSB or reference CSI-RS resource, so as to receive with the same corresponding reception parameter, and the target macro-scale parameter may be determined through QCL type configuration. Similarly, if the network device configures the QCL reference signal of the target downlink channel to be the reference SSB or the reference CSI-RS resource through the TCI state and the QCL type is configured to be QCL-type, the terminal device may receive the target downlink channel using the same reception beam (i.e., spatial Rx parameter) as the reference SSB or the reference CSI-RS resource. In general, the target downlink channel and its reference SSB or reference CSI-RS resource are transmitted by the same TRP, the same panel (panel) or the same beam on the network device side. If the transmission TRP or transmission panel or transmission beam of two downlink signals or downlink channels are different, different TCI states can be configured.

In this embodiment of the present application, the DCI may include a first indication field (or called TCI status indication field), where K is a positive integer, and for example, the first indication field may be 3 bits, and the first indication field may be used to indicate 000 to 111, that is, 8 TCI values.

In this embodiment of the present application, one TCI value in DCI may indicate one TCI status identifier (identity, ID), or may also indicate a plurality of TCI status IDs, for example, 2 TCI status IDs, different TCI values may indicate the same number of TCI status IDs, or may also indicate different numbers of TCI status IDs, and specifically, the number of TCI status IDs indicated by each TCI value and the indicated TCI status ID may be determined by the network device.

It should be understood that in the embodiment of the present application, the TCI value may also be referred to as a code point (code point) value, and then the value of the first indication field in the DCI may be referred to as a TCI value or a code point value, which may indicate one or more TCI status IDs.

In this embodiment of the present application, a terminal device may receive a MAC CE sent by a network device, where the MAC CE includes a first bit bitmap (bitmap) and TCI status indication information, where the first bit bitmap (bitmap) may be used to determine the number of TCI status IDs indicated by each of the K TCI values, and the TCI status indication information may be used to determine at least one TCI status ID indicated by each of the K TCI values, so that when the terminal device receives downlink control information (Downlink Control Information, DCI), the terminal device may learn the TCI value in the DCI, and further may determine at least one TCI status ID indicated by the TCI value according to the MAC CE.

As an example, the first bit bitmap may include K groups of bits, each group of bits may correspond to one TCI value, each group of bits in the first bit bitmap is used to determine the number of TCI status IDs indicated by the corresponding TCI value, and the number of bits included in each group of bits may be determined according to the maximum number of TCI status IDs indicated by the TCI value.

For example, if one TCI value corresponds to at most 2 TCI status IDs, each group of bits may be 1 bit, which is used to indicate that the number of TCI status IDs indicated by each TCI value is one or two.

For another example, if one TCI value corresponds to at most 3 TCI state IDs, each set of bits may be 2 bits, to indicate that the number of TCI states indicated by each TCI value is one, two or three, and by way of example and not limitation, 00 may be set to indicate one TCI state, 01 to indicate two TCI states, 10 and 11 to indicate three TCI states, or other indication manners may be adopted. In the following, a case where one TCI value indicates 2 TCI states at most is taken as an example, and when one TCI value indicates more TCI states, the TCI value may be indicated in a similar manner, and for brevity, a description thereof will be omitted.

The implementation of the first bit map and the TCI state indication information is described below in connection with specific embodiments.

Example 1:

each bit in the first bit map corresponds to a TCI value, and each bit may be used to indicate that the corresponding TCI value indicates one TCI state ID or two TCI state IDs, or each bit may be used to indicate whether the corresponding TCI value indicates a second TCI state ID, and if the corresponding TCI value indicates the second TCI state ID, it indicates that the TCI value indicates two TCI state IDs altogether, or does not indicate the second TCI state ID, and indicates that the TCI value indicates one TCI state ID altogether.

For example, the bit Bi in the first bit map takes a first value (e.g., 0) to indicate that the corresponding TCI value does not indicate the second TCI status ID, and the bit Bi takes a second value (e.g., 1) to indicate that the corresponding TCI value indicates the second TCI status ID, where i is 0,1, … …, K-1, where K is the number of bits occupied by the first bit map, or the total number of TCI values.

In this embodiment 1, the TCI state indication information includes a second bit map, each bit in the second bit map corresponds to one TCI state ID, and each bit in the second bit map is used to indicate that the corresponding TCI state ID is in an active state or a deactivated state. The second bitmap may be used to determine a first TCI status ID corresponding to each TCI value, and a manner of determining the first TCI status ID may be the same as an existing manner.

As an example, the bit Ti in the second bit bitmap takes a third value (e.g., 1) to indicate that the corresponding TCI status ID is in an activated state, and the bit Ti in the second bit bitmap takes a fourth value (e.g., 0) to indicate that the corresponding TCI status ID is in a deactivated state, where i is 0,1, … …, M-1, where M is the number of bits occupied by the second bit bitmap, or the total number of TCI status IDs. For example, if M is 128, the second bit bitmap may take 128 bits, each bit indicating whether a corresponding one of the TCI status IDs is active.

As an example, the number of active TCI state IDs indicated by the second bit map is smaller than a certain threshold, e.g. 8, i.e. at most 8 of the M TCI state IDs.

In one implementation, the second bit map is located before the first bit map.

If it is determined that at least one TCI value of the K TCI values indicates a second TCI state ID according to the first bit map, the TCI state indication information further includes the second TCI state ID indicated by each TCI value of the at least one TCI value.

In one implementation, 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, so that the terminal device may determine the second TCI state ID indicated by each of the at least one TCI value according to the magnitude of the TCI value.

In one implementation, a second TCI state ID indicated by the at least one TCI value is located after the first bit map.

Taking 8 TCI values as an example, if TCI value 000, TCI value 010 and TCI value 100 indicate the second TCI state ID, and the other TCI values do not indicate the second TCI state ID, the second TCI state IDs indicated by TCI value 000, TCI value 010 and TCI value 100, respectively, may be arranged in order of 000, 010 and 100. That is, a first TCI state ID after the first bit map is a second TCI state ID corresponding to a TCI value of 000, a second TCI state ID after the first bit map is a second TCI state ID corresponding to a TCI value of 010, and a third TCI state ID after the first bit map is a second TCI state ID corresponding to a TCI value of 100.

Thus, in this embodiment 1, after receiving DCI, the terminal device may determine a TCI value according to the DCI, then may determine an active TCI state ID according to a second bit map in the MAC CE, then may determine a first TCI state ID indicated by the TCI value according to a correspondence between the TCI value and an order of the active TCI state IDs, for example, if the TCI value is 000, may determine that the first active TCI state ID is the first TCI state ID indicated by the TCI value, or if the TCI value is 001, may determine that the second active TCI state ID is the first TCI state ID indicated by the TCI value, and so on.

Further, the terminal device may determine, according to the first bit bitmap, whether the TCI value indicates a second TCI state ID, and if so, the terminal device may determine, according to the magnitude of the TCI value and in combination with the magnitude order of the TCI value in the TCI value indicating the second TCI state ID, the second TCI state ID indicated by the TCI value in the TCI state IDs indicated by the TCI state indication information.

Next to the above example, if the TCI value in the DCI is 010, the terminal device may determine that the second TCI status ID after the first bit bitmap is the second TCI status ID indicated by the TCI value 010.

In some embodiments, the MAC CE may further include a serving cell ID (serving cell ID) and a bandwidth Part (BWP) ID.

As an example, the second bit map may be located after the serving cell ID and BWP ID.

Fig. 3 shows a schematic format diagram of a MAC CE according to embodiment 1 of the present application.

The MAC CE may include the following information:

1. serving cell ID and BWP ID occupy byte 1 (Oct 1) in the MAC CE;

2. the second bitmap, i.e. T0-T (N-2) x 8+7, is a bitmap of (N-1) x 8 TCI status IDs, and is used for indicating whether each TCI status ID of (N-1) x 8 TCI status IDs is activated, if the total number of TCI status IDs is 128, i.e. N is 17, the bitmap of 128 bits occupies 16 bytes of the MAC CE, i.e. byte 2 (Oct 2) -byte 17 (Oct 17);

3. The first bitmap is located behind the second bitmap, the length of the first bitmap can be determined according to the number of TCI values, if 8 TCI values exist, the first bitmap can be 8 bits (B0-B7) respectively used for indicating whether each TCI value indicates the second TCI state ID. Or if the number of TCI values is less than 8, for byte alignment, a reserved bit can be added before the first bitmap;

4. and the MAC CE further comprises second TCI state IDs respectively indicated by the at least one TCI value if the TCI state indication information determines that at least one TCI value exists according to the first bitmap to indicate the second TCI state ID, wherein the second TCI state IDs indicated by the at least one TCI value are arranged according to the size sequence 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 order of the at least one TCI value from small to large.

As one example, the TCI state ID indicated by the at least one TCI value may be disposed immediately adjacent, as shown in fig. 3.

As another example, for byte alignment, a reserved bit may be set before the TCI state ID, for example, if the TCI state ID is 7 bits, a reserved bit of 1 bit may be set before the TCI state ID, for example, as shown in fig. 4, or a reserved bit may be set after the TCI state ID, which is not limited in this application.

The terminal device may receive a physical downlink control channel (Physical Downlink Control Channel, PDCCH), determine a TCI value indicated by a first indication field in DCI of the PDCCH, and then determine a first TCI status ID indicated by the TCI value according to the TCI value in combination with a second bitmap in the MAC CE, for specific implementation reference to the foregoing related description.

Further, the terminal device may determine, according to the first bitmap, whether the TCI value indicates a second TCI state ID, and if so, the terminal device may determine, according to the magnitude of the TCI value, the second TCI state ID indicated by the TCI value from the TCI state IDs indicated after the first bitmap, for implementation reference to the foregoing related description.

Taking the first bitmap as 8 bits, the TCI status ID as 7 bits, and the second bitmap as 16 bytes as an example, the size of the number of bits occupied by the MAC CE (regardless of the bytes occupied by the serving cell ID and BWP ID) when the TCI value indicates a different number of TCI status IDs is described.

Case 1: if all TCI values indicate only one TCI status ID, the MAC CE may occupy 16 bytes (second bitmap) +1 byte (first bitmap), i.e. 17 bytes.

Case 2: if all TCI values indicate two TCI status IDs, based on the MAC CE format shown in fig. 3, the MAC CE may occupy 16 bytes (second bitmap) +1 byte (first bitmap) +8×7 bits, i.e. 24 bytes;

case 3: if all TCI values indicate two TCI status IDs, based on the MAC CE format shown in fig. 4, the MAC CE may occupy 16 bytes (second bitmap) +1 byte (first bitmap) +8×8 bits (7 bits TCI status id+1 reserved bits), i.e. 25 bytes.

Therefore, based on the format of the MAC CE of embodiment 1, the number of bytes occupied by the MAC CE ranges from 17 to 25 bytes.

Example 2:

each bit in the first bit map corresponds to one TCI value, and each bit may be used to indicate the number of TCI status IDs indicated by the corresponding TCI value, or each bit may be used to indicate whether the corresponding TCI value indicates a second TCI status ID.

For example, the bit Bi in the first bit map takes a first value (e.g., 0) to indicate that the corresponding TCI value indicates two TCI status IDs, and the bit Bi takes a second value (e.g., 1) to indicate that the corresponding TCI value indicates one TCI status ID, where i is 0,1, … …, K-1, where K is the number of bits occupied by the first bit map, or the total number of TCI values.

The TCI state indication information may be used to indicate a TCI state ID indicated by each TCI value.

As an example, the TCI state indication information may be located after the first bit bitmap.

As an example, the TCI state IDs indicated by the TCI values are arranged in order of magnitude of the TCI values, for example, the TCI state IDs indicated by the TCI values may be arranged in order of magnitude of the TCI values from small to large, so that the terminal device may determine the TCI state IDs indicated by the TCI values according to the magnitude of the TCI values in the DCI.

In some embodiments, if the TCI status ID is not full in size, the reserved bits may be filled, e.g., the reserved bits may be filled before the TCI status ID such that the TCI status ID plus the reserved bits are full in size, e.g., if the TCI status ID occupies 7 bits, a reserved bit may be set before the 7 bits, as shown in fig. 5.

In other embodiments, the TCI status IDs are immediately adjacent to each other, i.e., no reserved bits are set between the TCI status IDs, so that the TCI status indication information may be the byte size actually occupied by the TCI status IDs, as shown in fig. 6.

Therefore, in this embodiment 2, after receiving the DCI, the terminal device may determine a TCI value according to the DCI, further may determine the number of TCI status IDs indicated by the TCI value according to the first bit map in the MAC CE, and then may determine, according to the size of the TCI value, the TCI status ID indicated by the TCI value from the TCI status IDs indicated by the TCI status indication information.

Fig. 5 and 6 are two schematic format diagrams of a MAC CE according to embodiment 2, respectively. The difference between fig. 5 and fig. 6 is that a reserved bit is set between TCI status IDs in the format shown in fig. 5, and TCI status IDs in the format shown in fig. 6 are immediately adjacent.

As shown in fig. 5 and 6, the MAC CE may include the following information:

1. serving cell ID and BWP ID occupy byte 1 (Oct 1) in the MAC CE;

2. the length of the first bitmap can be determined according to the number of the TCI values, and if the number of the TCI values in the DCI can be 8, the first bitmap can be 8 bits (B0 to B7) and is used for indicating the number of TCI status IDs indicated by each TCI value. Or if the number of TCI values is less than 8, for byte alignment, a reserved bit can be added before the first bitmap;

3. TCI status indication information including a TCI status ID indicated by each TCI value. The TCI state IDs indicated by each TCI value are arranged in order of magnitude of each TCI value. For example, the TCI status IDs indicated by each TCI value may be arranged in order of TCI values from small to large.

Further, the terminal device may receive a PDCCH, and according to the DCI of the PDCCH including the TCI value indicated by the first indication field and the first bitmap, may determine the number of TCI status IDs indicated by the TCI value, and then may determine, according to the first bitmap and the magnitude of the TCI value, a TCI status ID indicated by the TCI value from the TCI status IDs indicated by the TCI status indication information.

Taking 8 TCI values 000-111 as an example, if the network device configures that the TCI value and the TCI status ID have a corresponding relationship as shown in table 1, the network device may indicate the corresponding relationship through the first bitmap and the TCI status indication information in the MAC CE, where the MAC CE may be specifically shown in fig. 7.

TABLE 1

TCI value	TCI State ID
		000	2
001	4，5
		010	7，9
011	10，11
		100	15
101	25，29
		110	40
111	50，60

If the TCI value in the DCI is 101, the terminal device may determine that B5 is 1, that is, the TCI value 101 indicates two TCI status IDs, and may determine, according to the first bitmap, the number of TCI status IDs indicated by other TCI values, further, the terminal device may search, in the TCI status indication information after the first bitmap, the TCI status ID indicated by the TCI value 101, and may determine, according to the first bitmap, that the 9 th and 10 th TCI status IDs in the TCI status indication information correspond to the TCI value 101, that is, the TCI status IDs indicated by the TCI value 101 are included in

bytes

11 and 12, that is, 25 and 29.

Taking the first bitmap as 8 bits and the TCI status ID as 7 bits as an example, the number of bits occupied by the MAC CE (regardless of the bytes occupied by the serving cell ID and BWP ID) when the TCI value indicates a different number of TCI status IDs is described.

Case 1: if each TCI value indicates only one TCI status ID, based on the MACCE format shown in fig. 5, the MAC CE may occupy 1 byte (first bitmap) +8*1 bytes (7 bits TCI id+1 reserved bits), i.e. 9 bytes.

Case 2: if each TCI value indicates two TCI status IDs, based on the MAC CE format shown in fig. 5, the MAC CE may occupy 1 byte (first bitmap) +8*2 bytes, i.e., 17 bytes.

Then, based on the MAC CE format shown in fig. 5, the number of bytes occupied by the MAC CE ranges from 9 to 17 bytes.

Case 3: if each TCI value indicates only one TCI status ID, based on the MAC CE format shown in fig. 6, the MAC CE may occupy 1 byte (first bitmap) +8×7 bits, i.e., 8 bytes.

Case 4: if each TCI value indicates two TCI status IDs, based on the MAC CE format shown in fig. 6, the MAC CE may occupy 1 byte (first bitmap) +8×14 bits, i.e., 15 bytes.

Then, based on the MAC CE format shown in fig. 6, the number of bytes occupied by the MAC CE ranges from 8 to 15 bytes.

Therefore, one byte can be saved by adopting the MAC CE format shown in fig. 6, as opposed to the MAC CE format shown in fig. 5.

Fig. 8 is a schematic block diagram of a method of wireless communication according to another embodiment of the present application, as shown in fig. 8, the method 300 including at least in part the following:

s310, a terminal device receives a Media Access Control (MAC) Control Element (CE) sent by a network device, wherein the MAC CE comprises K groups of Transmission Configuration Indication (TCI) state Identification (ID) and K groups of indication information respectively corresponding to the K groups of TCI state IDs;

Each group of TCI state IDs in the K groups of TCI state IDs includes two adjacent TCI state IDs, each group of TCI state IDs corresponds to one TCI value in downlink control information DCI, one group of indication information in the K groups of indication information is used for indicating whether the corresponding group of TCI state IDs is activated, and K is the total number of the TCI values.

For convenience of distinction and explanation, this embodiment will be described as embodiment 3, in which embodiment 3, one TCI value corresponds to a set of TCI state identification IDs, each of which may be used to indicate a plurality of TCI state IDs corresponding to the corresponding TCI value, for example, 2 TCI state IDs, and a set of indication information, each of which is used to indicate at least one TCI state ID activated from among the plurality of TCI state IDs corresponding to the corresponding TCI value.

It should be understood that, in this embodiment 3, the plurality of TCI state IDs corresponding to each TCI value is not necessarily the TCI state ID actually indicated by the TCI value, and it is necessary to further determine, in combination with the indication information corresponding to the TCI value, the activated TCI state ID from the plurality of TCI state IDs corresponding to the TCI value.

In this embodiment 3, the number of bits occupied by the set of TCI state IDs indicated by each TCI value is the same, and therefore, the size of the number of bits occupied by each set of TCI state IDs is determined according to the maximum number of TCI state IDs indicated by the TCI value.

For example, if the first TCI value indicates one TCI state ID and the second TCI value indicates two TCI state IDs, the minimum number of bits occupied by each group of TCI state IDs indicates two TCI state IDs;

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 indicates three TCI state IDs, then the minimum number of bits occupied by each group of TCI state IDs indicates three TCI state IDs.

In the following, taking an example that each group of TCI state IDs includes two TCI state IDs as an example, the corresponding group of indication information may include two bits B0 and B1, respectively indicating whether each of the two TCI state IDs is activated.

For example, the bit B0 takes a first value (e.g., 1) for indicating that the corresponding TCI state ID is active, and the bit B0 takes a second value (e.g., 0) for indicating that the corresponding TCI state ID is inactive; the bit B1 takes a first value (e.g., 1) for indicating that the corresponding TCI state ID is active, and the bit B1 takes a second value (e.g., 0) for indicating that the corresponding TCI state ID is inactive.

As an example, at least one of the bits B0 and B1 takes the first value, i.e. each TCI value indicates at least one TCI status ID.

As an example, each of the two bits in each set of indication information is located before the TCI state ID corresponding to said each bit. For example, if B0 is used to indicate whether TCI status flag T0 is active, then B0 may be located before T0.

As an example, the TCI state IDs of each group are arranged in order of magnitude of the corresponding TCI values, for example, two TCI state IDs corresponding to each TCI value may be arranged in order of magnitude of the TCI values.

For example, if the first TCI value is smaller than the second TCI value, two TCI state IDs in a set of TCI state IDs corresponding to the first TCI value are located before two TCI state IDs in a set of TCI states corresponding to the second TCI value.

Fig. 9 is a schematic format diagram of a MAC CE according to embodiment 3.

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 and BWP ID occupy byte 1 (Oct 1) in the MAC CE;

2. 8 groups of TCI state IDs and 8 groups of indication information;

each set of TCI state IDs includes two TCI state IDs, and each set of indication information includes bits B0 and B1 for indicating the activation or deactivation of the corresponding TCI state ID, respectively.

The 8 TCI values respectively correspond to two TCI state IDs and two indication information corresponding to the two TCI state IDs are arranged according to the size sequence of each TCI value. For example, the TCI values are arranged in order from small to large. The first byte and the second byte after the serving cell ID and BWP ID include two TCI state IDs corresponding to TCI value 000 and two indication information corresponding to the two TCI state IDs, the third byte and the fourth byte include two TCI state IDs corresponding to TCI value 001 and two indication information corresponding to the two TCI state IDs, and so on.

Therefore, in this embodiment 3, after receiving DCI, the terminal device may determine a TCI value according to the DCI, further may determine, according to the magnitude of the TCI value, a set of TCI state IDs corresponding to the TCI value from the K sets of TCI state IDs, and further determine, in combination with a set of indication information corresponding to the set of TCI state IDs, an activated TCI state ID from the set of TCI state IDs.

For example, if the TCI value is 001, the terminal device may determine that a set of TCI state IDs and a set of indication information corresponding to the TCI value 001 are included in the fourth and fifth bytes in the MAC CE, and then may determine the active TCI state ID according to the set of TCI state IDs and the set of indication information.

For the correspondence between TCI values and TCI status IDs shown in table 1, if the MAC CE format shown in fig. 9 is used, the content of the MAC CE may be as shown in fig. 10.

If the TCI value in the DCI received by the terminal device is 100, the terminal device may search the tenth and eleventh bytes in the MAC CE, determine that two TCI status IDs corresponding to the TCI value 100 are 15 and 20, further combine the indication information corresponding to the two TCI status IDs are 15 and 20, determine that the TCI status ID15 is activated, and determine that the TCI status ID20 is deactivated, and determine that the target TCI status ID indicated by the TCI value 100 is the TCI status ID15.

It should be understood that the above correspondence between TCI values and TCI status IDs is only an example, and other correspondence may be also used, which is not limited in the embodiment of the present application.

Therefore, in this embodiment 3, if the TCI status ID is 7 bytes and the corresponding instruction 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 to 16 bits.

In another implementation manner of this embodiment 3, the K-group indication information is located before the K-group TCI state ID, where the K-group indication information may be 16 bits of bitmap, the K-group TCI state IDs are 16 TCI state IDs, and two TCI states corresponding to the same TCI value are arranged in order according to the magnitude order of the corresponding TCI values, or a reserved bit may be set, and the 16 bits of bitmap may be used to indicate that the 16 TCI state IDs are activated or deactivated. The terminal device may determine, according to the size of the TCI value in the DCI, two TCI state IDs corresponding to the TCI value in the 16 TCI state IDs, and further determine an activated TCI state ID in the two TCI state IDs by combining the values of the two bits corresponding to the TCI value in the 16 bits.

As can be seen from the foregoing embodiments 1 to 3, the MAC CE shown in fig. 3 and 4 occupies 16 bytes at least, the MAC CE shown in fig. 6 occupies 15 bytes at most, the MAC CE format shown in fig. 9 is a fixed 16-byte MAC CE format, and the MAC CE formats shown in fig. 3 and 5 are configured with reserved bits, aligned bytes, so that the terminal device can find the position of the TCI status ID conveniently, and therefore, the use of the MAC CE format shown in fig. 6 is beneficial to reducing signaling overhead.
