S210, a terminal device receives a media access control MAC control element CE sent by a network device, where the MAC CE includes a first bit map and transmission configuration indication TCI status indication information, where each bit in the first bit map corresponds to a TCI value in downlink control information DCI, each bit is used to indicate the number of TCI status IDs indicated by a 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.
Optionally, in this embodiment of the present application, one TCI state may include the following configuration:
1. a TCI status identifier (identity, ID) for identifying a TCI status;
2. quasi-co-located (QCL) information 1;
3. QCL information 2.
Wherein, one QCL information may include the following information:
the QCL type configuration may be, for example, one of QCL type a (QCL typea), QCL type b (QCL typeb), QCL type c (QCL typec) or QCL type d (QCL typed);
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 (e.g., 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 piece of QCL information is one of QCL type a, QCL type b, and QCL type c, and if another piece of QCL information is configured, the QCL type of the QCL information is QCL type d.
Wherein, the different QCL type configurations are defined as follows:
1. QCL-type A: { Doppler shift, Doppler spread, average delay, delay spread };
2、QCL-TypeB:{Doppler shift,Doppler spread};
3、QCL-TypeC:{Doppler shift,average delay};
4. QCL-type D: { Spatial Rx parameter (Spatial Rx parameter) }.
If the QCL Reference Signal of the target downlink Channel is configured as a Reference synchronization Signal block (synchronization/PBCH block, SS/PBCH block) or Reference Channel State Information Reference Signal (CSI-RS) resource by the network device through the TCI State, and the QCL type is configured as QCL-type a, QCL-type b, or QCL-type c, the terminal device may assume that the target large-scale parameters of the target downlink Channel and the Reference SSB or Reference CSI-RS resource are the same, and thus receive using the same corresponding receiving parameters, and the target large-scale parameters may be determined through QCL type configuration. Similarly, if the network device configures the QCL reference signal of the target downlink channel as the reference SSB or the reference CSI-RS resource through the TCI state, and the QCL type is configured as QCL-type, the terminal device may receive the target downlink channel using the same reception beam (i.e., Spatial Rx parameter) as that for receiving the reference SSB or the reference CSI-RS resource. Generally, 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. Different TCI states can be configured if the TRP or panel or transmit beam transmission of the two downlink signals or downlink channels is different.
In this embodiment, the DCI may include a first indication field (or referred to as a TCI status indication field), where the first indication field may be used to indicate K TCI values, where K is a positive integer, for example, the first indication field may be 3 bits, and then the first indication field may be used to indicate 000 to 111, that is, 8 TCI values.
In this embodiment of the application, one TCI value in the DCI may indicate one TCI status identifier (identity, ID), or may also indicate multiple TCI status IDs, for example, 2 TCI status IDs, and 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 the TCI status IDs indicated by each TCI value and the indicated TCI status IDs 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 codepoint (codepoint) value, and then the value of the first indication field in the DCI may be referred to as a TCI value or a codepoint value, which may indicate one or more TCI state 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 bitmap (bitmap) and TCI status indication Information, where the first bitmap (bitmap) may be used to determine the number of TCI status IDs indicated by each TCI value 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 TCI value of the K TCI values, so that when the terminal device receives Downlink Control Information (DCI), the terminal device may know the TCI value in the DCI, and further may determine the 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 values, 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 values.
For example, if a TCI value corresponds to 2 TCI status IDs at most, 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 3 TCI status IDs at most, each group of bits may be 2 bits, and the number of the TCI statuses indicated by each TCI value is one, two, or three, by way of example and not limitation, 00 may be set to indicate one TCI status, 01 indicates two TCI statuses, and 10 and 11 indicate three TCI statuses, or other indication manners may also be adopted. Hereinafter, it is described by taking an example that one TCI value indicates 2 TCI states at most, and when one TCI value indicates more TCI states, the TCI values may be indicated in a similar manner, and for brevity, detailed description is omitted here.
The following describes an implementation manner of the first bit map and the TCI status indication information in conjunction with a specific embodiment.
Example 1:
each bit in the first bit bitmap corresponds to one TCI value, and each bit may be used to indicate that the corresponding TCI value indicates one TCI status ID or two TCI status IDs, or each bit may be used to indicate whether the corresponding TCI value indicates a second TCI status ID, and if the second TCI status ID is indicated, it indicates that the TCI value indicates two TCI status IDs in total, or does not indicate the second TCI status ID, it indicates that the TCI value indicates one TCI status ID in total.
E.g. bit B in the first bit mapiTaking a first value (e.g., 0) to indicate that the corresponding TCI value does not indicate a second TCI State ID, bit BiA second value (e.g., 1) is used to indicate that the corresponding TCI value indicates a second TCI status ID, where 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.
In this embodiment 1, the TCI status indication information includes a second bitmap, each bit in the second bitmap corresponds to one TCI status ID, and each bit in the second bitmap is used to indicate that the corresponding TCI status ID is in an activated status or a deactivated status. The second bitmap may be used to determine a first TCI status ID corresponding to each TCI value, and the manner of determining the first TCI status ID may be the same as that in the existing manner.
As an example, bit T in the second bitmapiTaking a third value (e.g., 1) for indicating that the corresponding TCI State ID is active, bit T in the second bitmapiTaking a fourth value (e.g., 0) is used 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 bitmap, or the total number of TCI status IDs. For example, if M is 128, the second bitmap may take 128 bits, each for indicating whether a corresponding TCI status ID is active.
As an example, the number of activated TCI status IDs indicated by the second bitmap is less than a certain threshold, for example, 8, that is, there are at most 8 activated TCI status IDs in the M TCI status IDs.
Optionally, 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 status ID according to the first bit bitmap, the TCI status indication information further includes the second TCI status ID indicated by each TCI value of the at least one TCI value.
Optionally, the second TCI status IDs indicated by the at least one TCI value are arranged according to the size order of the at least one TCI value, so that the terminal device may determine the second TCI status ID indicated by each of the at least one TCI value according to the size of the TCI value.
Optionally, the second TCI status ID indicated by the at least one TCI value is located after the first bitmap.
Taking 8 TCI values as an example, if the TCI value 000, the TCI value 010 and the TCI value 100 indicate the second TCI status ID, and other TCI values do not indicate the second TCI status ID, the second TCI status IDs indicated by the TCI value 000, the TCI value 010 and the TCI value 100, respectively, may be arranged in the order of 000, 010 and 100. That is, the first TCI status ID after the first bitmap is the second TCI status ID corresponding to the TCI value 000, the second TCI status ID after the first bitmap is the second TCI status ID corresponding to the TCI value 010, and the third TCI status ID after the first bitmap is the second TCI status ID corresponding to the TCI value 100.
Therefore, in this embodiment 1, after receiving the DCI, the terminal device may determine a TCI value according to the DCI, then determine an activated TCI status ID according to a second bitmap in the MAC CE, and then determine a first TCI status ID indicated by the TCI value according to a corresponding relationship between the TCI value and an order of the activated TCI status IDs, for example, if the TCI value is 000, it may determine that the first activated TCI status ID is the first TCI status ID indicated by the TCI value, or if the TCI value is 001, it may determine that the second activated TCI status ID is the first TCI status 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 status ID, and if the second TCI status ID is indicated, the terminal device may determine, according to the size of the TCI value, the second TCI status ID indicated by the TCI value in the TCI status IDs indicated by the TCI status indication information, in combination with a size order of the TCI value in the TCI value indicating the second TCI status ID.
Following the above example, if the TCI value in the DCI is 010, the terminal device may determine that a second TCI status ID after the first bitmap is the second TCI status ID indicated by the TCI value 010.
Optionally, in some embodiments, the MAC CE may further include a serving cell identification (serving cell ID) and a bandwidth Part (Band Width Part, BWP) ID.
As an example, the second bitmap 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, byte 1 in MAC CE (Oct 1);
2. the second bitmap, T0~T (N-2)*8+7If the total number of the TCI state IDs is 128, that is, N is 17, the 128-bit bitmap occupies 16 bytes of the MAC CE, that is, byte 2(Oct 2) -byte 17(Oct 17);
3. the length of the first bitmap can be determined according to the number of TCI values after the first bitmap is positioned behind the second bitmap, and if 8 TCI values exist, the first bitmap can be 8 bits (B)0~B 7) Respectively, for indicating whether each TCI value indicates a second TCI status ID. Or if the number of TCI values is less than 8, for byte alignment, a reserved bit may be added before the first bitmap;
4. and the MAC CE further includes second TCI state IDs respectively indicated by the at least one TCI value if it is determined that the at least one TCI value indicates the second TCI state ID according to the first bitmap, wherein the second TCI state IDs indicated by the at least one TCI value are arranged according to a size order of the at least one TCI value. For example, the second TCI state IDs 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 an example, the TCI status IDs indicated by the at least one TCI value may be set immediately adjacent as shown in fig. 3.
As another example, for byte alignment, a reserved bit may be set before the TCI status ID, for example, if the TCI status ID is 7 bytes, a reserved bit of 1 bit may be set before the TCI status ID, for example, as shown in fig. 4, or a reserved bit may be set after the TCI status ID, which is not limited in this application.
The terminal device may receive a 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 state ID indicated by the TCI value according to the TCI value and a second bitmap in the MAC CE, which is specifically described in the foregoing.
Further, the terminal device may determine whether the TCI value indicates a second TCI status ID according to the first bitmap, and if the second TCI status ID is indicated, the terminal device may determine, according to the size of the TCI value, the second TCI status ID indicated by the TCI value in the TCI status IDs indicated after the first bitmap, specifically implement the related description above.
Taking the first bitmap as 8 bits, the TCI state ID as 7 bytes, and the second bitmap as 16 bytes as an example, the size of the number of bits occupied by the MAC CE (without considering the bytes occupied by the serving cell ID and the BWP ID) when the TCI value indicates different numbers of TCI state IDs will be described.
Case 1: if all TCI values indicate only one TCI State ID, the MAC CE may occupy 16 bytes (first bitmap) +1 byte (second 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 (first bitmap) +1 byte (second bitmap) +8 × 7 bits, that is, 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 (first bitmap) +1 byte (second bitmap) +8 × 8 bits (7-bit TCI status ID +1 reserved bits), i.e., 25 bytes.
Therefore, the number of bytes occupied by the MAC CE ranges from 17 to 25 bytes based on the format of the MAC CE of embodiment 1.
Example 2:
each bit in the first bit bitmap 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.
E.g. bit B in the first bit mapiTaking a first value (e.g., 0) for indicating that the corresponding TCI value indicates two TCI State IDs, bit BiAnd taking a second value (for example, 1) to indicate that the corresponding TCI value indicates a 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 status indication information may be used to indicate the TCI status ID indicated by each TCI value.
As one example, the TCI status indication information may be located after the first bit map.
As an example, the TCI status IDs indicated by each TCI value are arranged according to the size order of each TCI value, for example, the TCI status IDs indicated by each TCI value may be arranged according to the order of the TCI values from small to large, so that the terminal device may determine the TCI status IDs indicated by the TCI values according to the size of the TCI values in the DCI.
In some embodiments, if the size of the TCI state ID is less than a whole byte, the reserved bits may be filled, for example, the reserved bits are filled before the TCI state ID so that the size of the TCI state ID plus the reserved bits is enough to a whole byte, for example, if the TCI state 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 size of the byte actually occupied by the TCI status IDs, as shown in fig. 6.
Therefore, in embodiment 2, after receiving the DCI, the terminal device may determine a TCI value according to the DCI, further determine the number of TCI status IDs indicated by the TCI value according to the first bitmap in the MAC CE, and then determine the TCI status ID indicated by the TCI value in the TCI status IDs indicated by the TCI status indication information according to the size of the TCI value.
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 reserved bits are provided between the TCI status IDs in the format shown in fig. 5, and the TCI status IDs are immediately adjacent in the format shown in fig. 6.
As shown in fig. 5 and 6, the MAC CE may include the following information:
1. serving cell ID and BWP ID, byte 1 in MAC CE (Oct 1);
2. the length of the first bitmap can be determined according to the number of the TCI values, and if the TCI values in the DCI can be 8, the first bitmap can be 8 bits (B)0~B 7) And respectively 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 may be added before the first bitmap;
3. TCI status indication information including a TCI status ID indicated by each TCI value. The TCI status IDs indicated by each TCI value are arranged according to the size sequence of each TCI value. For example, the TCI status IDs indicated by each TCI value may be arranged in the order of TCI values from small to large.
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, may determine the number of the TCI state IDs indicated by the TCI value, and then may determine the TCI state IDs indicated by the TCI value in the TCI state IDs indicated by the TCI state indication information according to the first bitmap and the size of the TCI value.
Taking 8 TCI values 000-111 as an example, if a TCI value configured by a network device and a TCI status ID have a corresponding relationship as shown in table 1, the network device may indicate the corresponding relationship through a first bitmap in an MAC CE and TCI status indication information, and in this case, 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 B5The number of the TCI state IDs indicated by the other TCI values may also be determined according to the first bitmap, and further, the terminal device may search for the TCI state ID indicated by the TCI value 101 in the TCI state indication information after the first bitmap, and may determine that the 9 th and 10 th TCI state IDs in the TCI state indication information correspond to the TCI value 101 according to the first bitmap, that is, the bytes 11 and 12 include the TCI state IDs indicated by the TCI value 101, that is, 25 and 29.
Taking the first bitmap as 8 bits and the TCI status ID as 7 bytes as an example, the number of bits occupied by the MAC CE when the TCI value indicates different numbers of TCI status IDs will be described (without considering the bytes occupied by the serving cell ID and the BWP ID).
Case 1: if each TCI value indicates only one TCI status ID, based on the MAC CE format shown in fig. 5, the MAC CE may occupy 1 byte (first bitmap) +8 × 1 byte (TCI ID of 7 bits +1 reserved bits), that is, 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 state 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, with the MAC CE format shown in fig. 6, one byte can be saved, 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 corresponding to the K groups of TCI state IDs respectively;
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 one TCI value in the DCI, one group of indication information in the K groups of indication information is used to indicate whether the corresponding group of TCI status IDs is activated, and K is the total number of the TCI values.
For convenience of differentiation and illustration, this embodiment is referred to as embodiment 3, in this embodiment 3, one TCI value corresponds to one group of TCI state identification IDs and one group of indication information, each group of TCI state identification IDs may be used to indicate a plurality of TCI state IDs corresponding to the corresponding TCI value, for example, 2 TCI state IDs, and each group of indication information is used to indicate at least one activated TCI state ID in the plurality of TCI state IDs corresponding to the corresponding TCI value.
It should be understood that in this 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 activated TCI status ID in the multiple TCI status IDs corresponding to the TCI value needs to be further determined in combination with the indication information corresponding to the TCI value.
In this embodiment 3, the number of bits occupied by one group of TCI status IDs indicated by each TCI value is the same, and therefore, the size of the number of bits occupied by each group of TCI status IDs is determined according to the maximum number of TCI status IDs indicated by the TCI value.
For example, if the first TCI value indicates one TCI status ID and the second TCI value indicates two TCI status IDs, the size of the number of bits occupied by each group of TCI status IDs can indicate at least two TCI status IDs;
for another example, if the first TCI value indicates one TCI status ID, the second TCI value indicates two TCI status IDs, and the third TCI indicates three TCI status IDs, the size of the number of bits occupied by each group of TCI status IDs can indicate at least three TCI status IDs.
In the following, taking an example that each set of TCI status IDs includes two TCI status IDs, the corresponding set of indication information may include two bits B0And B1Indicating whether each of the two TCI status IDs is active, respectively.
For example, the bit B0Taking a first value (e.g. 1) for indicating that the corresponding TCI State ID is active, the bit B0Take a second value (e.g., 0) for indicating that the corresponding TCI state ID is deactivated; the bit B1Taking a first value (e.g. 1) for indicating that the corresponding TCI State ID is active, the bit B1A second value (e.g., 0) is taken to indicate that the corresponding TCI state ID is deactivated.
As an example, the bit B0And bit B1At least one bit of the first value indicates that each TCI value indicates at least one TCI status ID.
As an example, each of the two bits in each set of indication information precedes the TCI status ID to which it corresponds. For example, if B0For indicating TCI state identification T0If it is activated, then B0Can be located at T0And (3) before.
As an example, each set of TCI state IDs is arranged according to the size order of the corresponding TCI values, for example, two TCI state IDs corresponding to each TCI value may be arranged according to the order of the TCI values from small to large.
For example, if the first TCI value is less than the second TCI value, two TCI state IDs of a set of TCI state IDs corresponding to the first TCI value precede two TCI state IDs of 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 status ID occupies 7 bits, and the indication information corresponding to each TCI status ID occupies 1 bit as an example, the MAC CE may include the following information:
1. serving cell ID and BWP ID, byte 1 in MAC CE (Oct 1);
2. 8 sets of TCI status IDs and 8 sets of indication information;
each set of TCI State IDs includes two TCI State IDs, and each set of indication information includes bit B0And B1For indicating the corresponding TCI status ID activation or deactivation, respectively.
The two TCI status IDs corresponding to the 8 TCI values and the two indication information corresponding to the two TCI status IDs are arranged according to the size sequence of each TCI value. For example, the TCI values are arranged in descending order. The first byte and the second byte after the serving cell ID and the BWP ID include two TCI state IDs corresponding to the 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 the TCI value 001 and two indication information corresponding to the two TCI state IDs, and so on.
Therefore, in this embodiment 3, after receiving the DCI, the terminal device may determine a TCI value according to the DCI, further determine a group of TCI state IDs corresponding to the TCI value in the K groups of TCI state IDs according to the size of the TCI value, and further determine the activated TCI state ID in the group of TCI state IDs by combining with a group of indication information corresponding to the group of TCI state IDs.
For example, if the TCI value is 001, the terminal device may determine that a group of TCI status IDs and a group 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 activated TCI status ID according to the group of TCI status IDs and the group of indication information.
For the correspondence between the TCI value and the TCI status 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.
If the TCI value in the DCI received by the terminal device is 100, the terminal device may search the tenth byte and the eleventh byte in the MAC CE, determine that the two TCI state IDs corresponding to the TCI value 100 are 15 and 20, further combine the indication information corresponding to the two TCI state IDs 15 and 20, may determine that the TCI state ID15 is activated, and the TCI state ID20 is deactivated, and may determine that the target TCI state ID indicated by the TCI value 100 is the TCI state ID 15.
It should be understood that the above correspondence relationship between the TCI value and the TCI status ID is only an example, and other correspondence relationships may also be used, which is not limited in the embodiment of the present application.
Therefore, in 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 (without considering the bytes occupied by the serving cell ID and the BWP ID) is fixed to 16 bits.
In another implementation manner of this embodiment 3, the K groups of indication information are located before the K groups of TCI state IDs, in this case, the K groups of indication information may be 16-bit bitmaps, the K groups of TCI state IDs are 16 TCI state IDs, the K groups of TCI state IDs are arranged according to the size sequence of the corresponding TCI values, two TCI states corresponding to the same TCI value are arranged in close proximity, or a reserved bit may also be set, and the 16-bit bitmaps may be used to indicate activation or deactivation of the 16 TCI state IDs. The terminal device may determine 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 determine the activated TCI state ID among the two TCI state IDs by combining values of two bits corresponding to the TCI value among the 16 bits.
It can be seen from the above embodiments 1 to 3 that the MAC CE shown in fig. 3 and 4 occupies at least 16 bytes, the MAC CE shown in fig. 6 occupies at most 15 bytes, and the MAC CE format shown in fig. 9 is fixed 16 bytes, and the MAC CE formats shown in fig. 3 and 5 are convenient for the terminal device to find the position of the TCI state ID due to the fact that the reserved bits and the bytes are aligned, so that the MAC CE format shown in fig. 6 is beneficial to reducing signaling overhead.
