In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is provided.

(1) Beam indication

After beam measurement and beam reporting, the network can perform beam indication on the downlink and uplink channels or reference signals, and the beam indication is used for establishing a beam link between the network and the UE, so that the transmission of the channels or the reference signals is realized.

For beam indication of the physical downlink control channel (Physical downlink control channel, PDCCH), the network configures K transmission configuration indication (Transmission Configuration Indication, TCI) states (states) for each control resource set (Control resource set, CORESET) using radio resource control (Radio Resource Control, RRC) signaling, with 1 TCI state being indicated or activated by a MAC CE when K >1, and no additional MAC CE commands being required when k=1. When the UE listens to the PDCCH, the same Quasi co-location (QCL), i.e., the same TCI state, is used for all search spaces (search spaces) within the CORESET to listen to the PDCCH. The reference signal (reference signal) in this TCI state (e.g., periodic CSI-RS resource, semi-persistent CSI-RS resource, SS block, etc.) is spatial QCL to the UE-specific PDCCH DMRS port. The UE can learn which reception beam to use to receive the PDCCH according to the TCI state.

For beam indication of a physical downlink shared channel (Physical downlink shared channel, PDSCH), the network configures M TCI states through RRC signaling, then activates TCI states corresponding to up to 8 code points (codepoints) using MAC CE commands, and then informs the TCI state through the 3-bit TCI field of the DCI, the reference signal in the TCI state is QCL with the DMRS port of the PDSCH to be scheduled. The UE can know which reception beam to use to receive PDSCH according to the TCI state.

For beam indication of the CSI-RS, when the CSI-RS type is periodical CSI-RS, the network configures QCL information for the CSI-RS resource through RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network indicates QCL information thereof when one CSI-RS resource is activated from among RRC configured CSI-RS resource sets through a MAC CE command. When the CSI-RS type is aperiodic CSI-RS, the network configures QCL for CSI-RS resource through RRC signaling and uses DCI to trigger CSI-RS.

For beam indication of the physical uplink control channel (Physical Uplink Control Channel, PUCCH), the network configures spatial relation information for each PUCCH resource using RRC signaling through the parameter PUCCH-spacialrelation info, and when spatial relation information configured for PUCCH resource contains multiple, either indicates or activates one spatial relation information using MAC-CE. When spatial relation information configured for PUCCH resource contains only 1, no additional MAC CE command is required.

For beam indication of PUSCH, the spatial relation information of PUSCH is that when DCI carried by PDCCH schedules PUSCH, each SRI code of SRI field in DCI indicates one SRI, which is used to indicate spatial relation information of PUSCH.

For beam indication of SRS, when the SRS type is periodic SRS, the network configures spatial relation information for SRS resource through RRC signaling. When the SRS type is semi-persistent SRS, the network activates spatial relation information through a MAC CE command. When the SRS type is an aperiodic SRS, the network configures spatial relation information for SRS resource through RRC signaling and can be updated through MAC CE commands.

(2) Unified TCI architecture

In the related art, a new TCI architecture (frame) is introduced, which may be referred to as a unified TCI architecture (unified TCI framework), i.e., the same beam indicated by the network using MAC CE and/or DCI may be used for multiple channel transmission, which may also be referred to as a common beam (common beam).

Both modes (or types) including joint TCI (joint TCI) and independent TCI (separate TCI) in unified TCI framework are configured by the RRC signaling of the network.

The network configures a TCI state pool (TCI state pool) through RRC signaling, with join TCI state and separate DL TCI state being the same one pool, separate UL TCI state using the other pool.

The network activates 1 or more TCI states using MAC CE commands. When the MAC CE activates the TCI state corresponding to 1 codepoint, the activated TCI state is directly applied to the target signal. When the MAC CE activates TCI states corresponding to a plurality of codepoints, the network re-uses TCI field in the DCI to indicate one codepoint to which the TCI state corresponding to the codepoint is applied. The number of codepoints is at most 8.TCI field is 3bits.

For joint TCI, each codepoint corresponds to 1 TCI state.

For separation TCI, each codepoint may correspond to one DL TCI state and 1 UL TCI state, or 1 DL TCI state, or 1 UL TCI state.

It should be noted that, the beam information mentioned in the embodiment of the present application may also be referred to as: identification information of beams, spatial relationship (spatial relation) information, spatial transmit filter (spatial domain transmission filter) information, spatial receive filter (spatial domain reception filter) information, spatial filter (spatial filter) information, transmission configuration indication state (TCI state) information, quasi co-location (QCL) information, QCL parameters, and the like. The downstream beam information may be generally represented using TCI state information or QCL information, among others. Upstream beam information may typically be represented using TCI state information or spatial relation information.

The information transmission method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 2, an embodiment of the present application provides an information transmission method, including:

step 201: the first node device obtains an activation command, where the activation command is used to activate at least one TCI state corresponding to a TCI state type indicated by the unified transmission configuration.

The first node device in the embodiment of the application includes, but is not limited to, a terminal and a TRP.

Alternatively, the information transmission method of the embodiment of the present application is applicable to a multi-TRP scenario. The at least one unified transmission configuration indication status type (unified TCI state type) corresponds to at least two target IDs, optionally one TRP associated with each target ID. The method of the present embodiment configures one or more unified TCI state type for a plurality of TRPs, and in the case of configuring one unified TCI state type, all TRPs share one unified TCI state type of the configuration. In the case where a plurality of unified TCI state type are configured, each TRP may correspond to one unified TCI state type.

The activation command may be transmitted through a medium access control unit (MAC CE).

In this embodiment of the present application, the first node device obtains an activation command, where the activation command is used to activate a TCI state corresponding to at least one unified transmission configuration indicator TCI state type. The unified transmission configuration indication TCI state is activated through the activation command, and the unified TCI state types respectively corresponding to the activated unified TCI state can be applied to different TRPs, and for each TRP, the beam determined by the corresponding unified TCI state can be used for multiple channel transmission on the TRP, namely, the common beam information on each TRP is determined, and then the common beam transmission of multiple TRPs can be realized.

Optionally, the activation command includes at least one of:

wherein each unified TCI state type corresponds to at least one of the target IDs.

In an embodiment of the present application, for the first signaling field, it is used to indicate whether there is a code point corresponding to each unified TCI status type or target ID configured in a set of code points (which may be all code points or part of code points in the activate command). For example, each group of code points in table 1 includes 2 code points corresponding to 2 unified TCI state types or target IDs, respectively, wi, j=0 indicates that no code point corresponding to the j-th unified TCI state type or target ID exists in the i-th group of code points, wi, j=1 indicates that a code point corresponding to the j-th unified TCI state type or target ID exists in the i-th group of code points.

In an embodiment of the present application, for the fifth signaling domain, when the codepoint corresponds to unified TCI state type or the target ID, the TCI state corresponding to the codepoint includes a plurality of TCI states or 1 TCI state, for example: contain DL TCI state and UL TCI state, or contain DL TCI state or UL TCI state only.

When each TCI state in the codepoint corresponds to unified TCI state type or the target ID, the TCI state in the codepoint corresponding to each unified TCI state type or the target ID is indicated to contain a plurality of or 1 TCI states.

For example, as shown in table 7, the codepoints correspond to unified TCI state type or the destination IDs, that is, the TCI state associated with each codepoint is a unified TCI state type TCI state or a TCI state of a destination ID, and the fifth signaling field indication parameter P corresponding to each codepoint, p=0, indicates that the codepoint corresponds to DL TCI state or UL TCI state; p=1 indicates that the codepoint corresponds to DL TCI state and UL TCI state.

TABLE 7

For example, as shown in table 8, each TCI state in the codepoint corresponds to unified TCI state type or a target ID, each TCI state in the TCI state associated with the codepoint corresponds to one unified TCI state type or a target ID, each TCI state in the codepoint corresponds to a fifth signaling field indication parameter P, and p=0 indicates that some unified TCI state type or target ID corresponds to DL TCI state or UL TCI state in each unified TCI state type or target ID corresponding to the TCI state associated with the codepoint; p=1 indicates that one unified TCI state type or target ID corresponds to DL TCI state and UL TCI state among unified TCI state type or target IDs corresponding to TCI state associated with the codepoint.

TABLE 8

In an embodiment of the present application, for the sixth signaling domain, optionally, each codepoint is arranged according to a preset sequence, and corresponds to a number or a configuration value of each unified TCI state type in the configuration signaling (signaling for configuring a unified TCI status type), or corresponds to each target ID, respectively. Optionally, in all TCI state IDs corresponding to codepoints, each TCI state ID is arranged according to a preset sequence, and corresponds to each number or configuration value of unified TCI state type in the configuration signaling, or corresponds to each target ID.

For example, TCI state IDs of TCI states corresponding to respective codepoints are arranged in accordance with numbers or configuration values of unified TCI state type corresponding to the codepoints or a preset order of respective target IDs. As shown in table 9, for example, in order: TCI state ID corresponding to unified TCI state type of a first unified TCI state type or configuration value (e.g., joint) or to codepoint of a first target ID, TCI state ID corresponding to unified TCI state type of a second unified TCI state type or configuration value (e.g., joint) or to codepoint of a second target ID, … ….

TABLE 9

For example, in the TCI state IDs of the TCI states corresponding to the codepoints, the arrangement is performed in accordance with the number or the configuration value of unified TCI state type corresponding to the TCI state IDs or the preset order of the respective target IDs. For example, as shown in table 10, in the TCI state ID of each codepoint, in order: TCI state ID corresponding to first unified TCI state type or unified TCI state type of a first value (e.g., joint) or first target ID, TCI state ID corresponding to second unified TCI state type or unified TCI state type of a second value (e.g., joint) or second target ID, … ….

Table 10

In an embodiment of the present application, for the seventh signaling domain, as shown in table 11, t=0 indicates that TCI states activated by the activate command are all corresponding to first unified TCI state type, or unified TCI state type with a configuration value of a first value (e.g. joint), or unified TCI state type corresponding to a first target ID;

similar to table 11, t=1 indicates that the TCI states activated by the activate command are all corresponding to the second unified TCI state type, or unified TCI state type configured to a second value (e.g., separation), or unified TCI state type corresponding to the second target ID;

TABLE 11

In an embodiment of the present application, for the eighth signaling domain, as shown in table 12, the code number corresponding to ID0 is P0,1P0,2P0,3, … …, and each code number is associated with a TCI state corresponding to ID 0; the codepoint number corresponding to ID1 is P1,1P1,2P1,3 … …, and each coded codepoint is associated with the TCI state corresponding to ID 1.

Table 12

Alternatively, if the plurality unified TCI state type are different, then a particular codepoint in the activate command or a particular TCI state in the codepoint corresponds to a particular unified TCI state type, e.g., the first TCI state in the codepoint may always be the TCI state corresponding to joint TCI state type, and the second and third TCI states may always be the DL TCI state and UL TCI state corresponding to separate TCI state type.

Optionally, in the case that the unified TCI state types or the target IDs corresponding to the plurality of code points in the activation command are different, each code point of the plurality of code points corresponds to a preset unified TCI state type or a preset target ID; for example, when the unified TCI state type of the network configuration is two types of a join and a separate, the first half code point in the activate command always corresponds to the join type, the second half code point always corresponds to the separate type, or the odd bit code point in the activate command always corresponds to the join type, and the even bit code point always corresponds to the separate type.

Or under the condition that the unified TCI state types or target IDs corresponding to the TCI states corresponding to the code points in the activation command are different, the TCI states corresponding to the code points correspond to preset unified TCI state types or preset target IDs. For example, when unified TCI state types of the network configuration are two types of joint and separation, the former TCI state in the code point is always the TCI state corresponding to the joint type, and the latter TCI state is always the DL TCI state and UL TCI state corresponding to the separation type.

Optionally, the code points in the activation command are arranged according to a first preset sequence, or the TCI states corresponding to the code points in the activation command are arranged according to a second preset sequence. For example, the first preset sequence is the number sequence or the value sequence (from small to large) of the unified TCI state types or the target IDs corresponding to the code points, and the code points in the activation command are arranged according to the sequence, or the second preset sequence is the number sequence or the value sequence (from small to large) of the unified TCI state types or the target IDs corresponding to the TCI states in the code points, and the TCI states in the code points are arranged according to the sequence.

Optionally, the method of the embodiment of the present application further includes:

acquiring Downlink Control Information (DCI) when the number of code points corresponding to at least one target ID in an activation command is greater than 1 or the number of code points corresponding to at least one unified TCI state type is greater than 1, wherein the DCI is used for indicating one code point of at least two code points corresponding to the at least one target ID or the at least one unified TCI state type;

Optionally, the multiple signaling domains of the DCI respectively indicate a code point, where each code point indicated by the signaling domain corresponds to a target ID or a unified TCI status type;

or, a signaling field of the DCI indicates a code point, where each TCI state corresponding to the code point corresponds to a target ID or a unified TCI state type.

For example, as shown in table 13, in each signaling field of DCI, one TCI field indicates one codepoint, and the indicated codepoint corresponds to a first unified TCI state type, and the other TCI field indicates a codepoint corresponding to a second unified TCI state type.

TABLE 13

As shown in table 14, one TCI field of DCI indicates one codepoint, and the TCI state corresponding to the indicated codepoint includes a TCI state corresponding to a first uniform TCI state type and a TCI state corresponding to a second uniform TCI state type.

TABLE 14

Optionally, the DCI further includes first indication information (including a TCI field or one other signaling field), where the first indication information is used to indicate a number or a configuration value of a unified TCI status type corresponding to a code point indicated by the DCI, or is used to indicate a target ID corresponding to the code point indicated by the DCI; each TCI field has a corresponding field containing the first indication information as shown in table 15 or in table 16;

TABLE 15

Table 16

Or, the first indication information is used for indicating a number or a configuration value of a unified TCI state type corresponding to a TCI state corresponding to a code point indicated by the DCI, or is used for indicating a target ID corresponding to a TCI state corresponding to a code point indicated by the DCI.

As shown in table 17, one corresponding field of the TCI field of the DCI includes first indication information, or, as shown in table 18, the TCI field includes first indication information for indicating the number or value of the type corresponding to the TCI state indicated by the TCI field, or the target ID.

TABLE 17

TABLE 18

Optionally, in the case that the code points indicated by the plurality of signaling domains of the DCI correspond to a plurality of different unified TCI state types or a plurality of different target IDs, the code points indicated by each signaling domain of the plurality of signaling domains correspond to a preset unified TCI state type or a preset target ID; for example, when the unified TCI status types of the network configuration are two types of joint and separation, the code points indicated by the first half of TCI field in the DCI always correspond to the joint type, the code points indicated by the second half of TCI field always correspond to the separation type, or the code points indicated by the TCI field of the odd-numbered bits in the DCI always correspond to the joint type, and the code points indicated by the TCI field of the even-numbered bits always correspond to the separation type.

Or in the case that each TCI state corresponding to a code point indicated by one signaling domain of the DCI corresponds to a plurality of different unified TCI state types or a plurality of different target IDs, the TCI state in the code point indicated by the one signaling domain corresponds to a preset unified TCI state type or a preset target ID. For example, when unified TCI status types of the network configuration are two types of joint and separate, in a code point indicated by TCI field of DCI, the former TCI state is always a TCI state corresponding to the joint type, and the latter TCI state is always a DL TCI state and UL TCI state corresponding to the separate type.

Optionally, before the first node device obtains the activation command, the method further includes:

at least one unified TCI state type of the network side equipment configuration is obtained.

In the embodiment of the present application, the first node device may acquire at least one unified TCI state type configured by the network side device through RRC signaling.

Optionally, at least one unified TCI state type of the network side device configuration is obtained, including at least one of the following:

a first item: acquiring a unified TCI state type according to a configuration signaling sent by network side equipment, wherein the configuration signaling is used for indicating the unified TCI state type; multiple TRPs may collectively correspond to the unified TCI state type in a multi-TRP scenario;

The second item: acquiring at least two unified TCI (traffic control interface) state types according to at least two configuration signaling sent by network side equipment, wherein each configuration signaling is used for indicating one unified TCI state type; for example, first unified TCI state type is unified TCI state type parameter configured by first RRC signaling with a value of joint or separation, second unified TCI state type is unified TCI state type parameter configured by second RRC signaling with a value of joint or separation, and so on; in a multi-TRP scenario, each TRP may correspond to one unified TCI state type of the configuration signaling indication;

third item: acquiring a unified TCI state type according to one configuration parameter in a configuration signaling sent by network side equipment, wherein the configuration parameter is used for indicating the unified TCI state type; multiple TRPs may collectively correspond to the unified TCI state type in a multi-TRP scenario;

fourth item: acquiring at least two unified TCI (traffic control interface) state types according to at least two configuration parameters in a configuration signaling sent by network side equipment, wherein each configuration parameter is used for indicating one unified TCI state type; for example, including a plurality of unified TCI state type parameters in the configuration signaling, the first unified TCI state type parameter unified TCI state type having a value of joint or separation, the second unified TCI state type parameter unified TCI state type2 having a value of joint or separation, and so on; in a multi-TRP scenario, each TRP may correspond to unified TCI state type indicated by one configuration parameter;

The fifth item: acquiring a unified TCI state type according to a configuration value of a configuration parameter in a configuration signaling sent by network side equipment, wherein the configuration value is used for indicating the unified TCI state type; multiple TRPs may collectively correspond to the unified TCI state type in a multi-TRP scenario;

sixth item: and acquiring at least two unified TCI state types according to at least two configuration values of configuration parameters in configuration signaling sent by the network side equipment, wherein each configuration value is used for indicating one unified TCI state type. For example, the configuration signaling includes a unified TCI state type parameter configured with 2 values, such as unified TCI state type = { joint, joint } or { joint, separator { separator, joint } or { separator, separator } or the like, i.e., each value is joint or separator, thereby determining 2 unified TCI status types; in a multi-TRP scenario, each TRP may correspond to unified TCI state type indicated by one configuration value.

Optionally, each of the at least one unified TCI state type corresponds to at least one target ID. For example, in a multi-TRP scenario, each TRP may correspond to a target ID, when each TRP corresponds to a unified TCI state type, then each unified TCI state type corresponds to a target ID, and when multiple TRPs correspond to the same unified TCI state type, then each unified TCI state type corresponds to multiple target IDs to which multiple TRPs correspond.

Optionally, for the first, third, and fifth items above, each unified TCI state type corresponds to at least two target IDs;

for the second, fourth, and sixth items described above, each unified TCI state type corresponds to a target ID.

Optionally, the at least two configuration signaling are ordered according to a third preset order, or the at least two configuration parameters are ordered according to a fourth preset order, or the at least two configuration values are ordered according to a fifth preset order.

The third preset sequence, the fourth preset sequence and the fifth preset sequence may be the same or different. The preset sequences may be the number sequence or the value sequence (e.g., ascending from small to large) of the unified TCI state type or the target ID corresponding to at least two configuration signaling, at least two configuration parameters, or at least two configuration values.

For example, when the configuration parameter unified TCI state type in the configuration signaling has a plurality of configuration values, the configuration values are sequentially arranged according to the type corresponding to the first target ID and the type corresponding to the second target ID, … …. (target IDs may not be explicitly configured at this time), such as { joint for ID1, joint for ID2}, { joint for ID1, separator for ID2}, { separator for ID1, joint for ID2}, { separator for ID1, separator for ID2} several possible values;

For example, when two values of the joint and the separator are configured, for example, unified TCI state type values of the joint and the separator are arranged in the contracted order of the configuration values of the plurality unified TCI state type, the joint is always arranged before the separator, that is { joint, separator } indicates that the type corresponding to the first target ID is the joint, the type corresponding to the second target ID is the separator, or the type corresponding to the second target ID is the joint, and the type corresponding to the first target ID is the separator. At this time, the contracted order may be irrelevant to the number order of the unified TCI status type or the target ID.

Optionally, each unified TCI state type of the plurality unified TCI state type corresponds to a target ID.

Alternatively, if the plurality unified TCI state type is different, the first type may be a specific type, such as a joint or a separation, for example, when 2 unified TCI state type are different, the order of values may always be { joint, separation }, where joint always precedes, or { separation joint }, where separation always precedes.

Optionally, the configuration signaling includes a target ID corresponding to a unified TCI state type corresponding to the configuration signaling, a configuration parameter, or a configuration value.

For example, when the configuration signaling configures one unified TCI state type, the configuration signaling carries one target ID; when the configuration signaling includes a plurality of unified TCI state type parameters, such as unified TCI state type1 and unified TCI state type2, the configuration signaling includes a plurality of target ID values corresponding to the plurality of unified TCI state type parameters respectively; when the unified TCI state type parameter in the configuration signaling includes a plurality of values, the configuration signaling includes a plurality of target ID values corresponding to the plurality of unified TCI state type values, respectively.

Optionally, the target ID is included in a configuration parameter (unified TCI state type parameter) of the configuration signaling.

For example: the target ID is included in the configuration signaling, where the unified TCI state type parameter in the configuration signaling is { joint, separation }, and the target ID parameter in the configuration signaling is { ID1, ID2}, ID1 corresponds to the first unified TCI state type with the joint value, and ID2 corresponds to the second unified TCI state type with the separation value.

The target ID may be included in the unified TCI state type parameter, and the unified TCI state type parameter has a value { joint, ID1; separation, ID 2).

Optionally, the at least two unified TCI state types correspond to the same configuration value, or the configuration values corresponding to the at least two unified TCI state types are not completely the same.

Optionally, the at least two target IDs correspond to the same unified TCI state type, or the unified TCI state types respectively corresponding to the at least two target IDs correspond to the same configuration value, or the configuration values corresponding to at least two unified TCI state types in the unified TCI state types respectively corresponding to the at least two target IDs are different.

At least one unified TCI state pool configured by the network side equipment is obtained.

Optionally, the configured TCI state type or at least two target IDs correspond to a common unified TCI state pool;

or, each configured TCI state type or each target ID corresponds to an independent unified TCI state pool;

wherein each of the configured at least one unified TCI state type corresponds to at least one target ID.

In an alternative implementation, each unified TCI state type or target ID corresponding pool is common. When at least one type value in the plurality of unified TCI state type is a join, the network configures 1 to joint TCI state pool, and the joint TCI state pool corresponds to unified TCI state type of all join values in the plurality of unified TCI state type; when at least one type of the plurality unified TCI state type has a separation value, the network configures 1 DL TCI state pool and 1 UL TCI state pool, or 1 DL TCI state pool, or 1 UL TCI state pool, and these separate TCI state pool correspond to all unified TCI state type of the plurality unified TCI state type having the separation value.

For example, the values of the plurality unified TCI state type include a join and a separation, the type corresponding to the first target ID is a join, the type corresponding to the second target ID is a separation, and the network configures the first pool to include a join TCI state and a DL TCI state for determining the join TCI state corresponding to the first target ID and the DL TCI state corresponding to the second target ID, and configures the second pool to include a UL TCI state for determining the UL TCI state corresponding to the second target ID.

In another alternative implementation, the pool corresponding to each unified TCI state type or each target ID is independent of each other. The network configures a plurality of pool, each pool corresponding to one unified TCI state type or one target ID. For example, the values of the plurality unified TCI state type include a join and a separation, the type corresponding to the first target ID is a join, the type corresponding to the second target ID is a separation, and the network configures the first pool to determine a join TCI state of the first target ID, and configures the second pool and the third pool to determine a DL TCI state and a UL TCI state of the second target ID.

In a specific embodiment of the present application, the network first sends RRC signaling to the UE, where unified TCI state type parameters in the signaling configure 2 values, namely unified TCI state type = { joint, separation }, where the first unified TCI state type is joint, corresponding to the first target ID (e.g. the first TRP), the second unified TCI state type is separation, corresponding to the second target ID (e.g. the second TRP), the network resends the MAC CE command, and uses unified TCI state for activating all target IDs or types, and the signaling format of the activation command is shown in table 19, where each code point corresponds to one unified TCI state type or TCI state of one target ID, and it should be noted that each signaling field in table 19 is not necessarily concurrent, and some may be default, for example: if the arrangement order of the codepoints corresponds to each target ID or each type value in a preset order, for example, in an order of numbers from small to large, the ID value signaling field and the type (C1 and C2) signaling field may be omitted. Alternatively, the signaling format of the activate command is shown in table 20, where the TCI state corresponding to each code point corresponds to a plurality or all of unified TCI state type or target IDs, and it should be noted that the signaling fields in table 20 need not exist at the same time, and some may be default, for example: if the arrangement order of the TCI states corresponding to the codepoint corresponds to each target ID or each type value in a preset order, for example, in order of numbers from small to large, the ID value signaling field and the type (C1 and C2) signaling field may be omitted.

In addition, all signaling fields of tables 21 and 22 may not exist at the same time, such as: the first MAC CE has a signaling field (e.g., m=0) indicating that the activation command is for a first type or a first target ID, the ID value signaling field (id=0) and the type signaling field (c=0) may be omitted, and the second MAC CE has a signaling field (e.g., m=1) indicating that the activation command is for a second type or a second target ID, the ID value signaling field (id=1) and the type signaling field (c=1) may be omitted.
