An embodiment of the present application provides a method for transmitting a configuration indication status indication. Referring to FIG. 1 , the following describes in detail through specific steps.

In a specific implementation, the method for determining the transmission configuration indication state provided by the following steps S101 to S102 may be executed by a baseband chip in the user equipment.

Step S101, receiving high-level configuration parameters.

The high-level configuration parameters delivered by the base station may include multiple control resource sets (CORESET), and each control resource set may correspond to at least one TCI state. After receiving the high-level configuration parameters, the user equipment can learn which control resource sets are configured by the base station and the TCI state corresponding to each control resource set.

In a specific implementation, the base station may deliver high-level configuration parameters to the user equipment through high-level signaling. The high-level signaling may be Radio Resource Control (Radio Resource Control, RRC) signaling, or may be a paging message or the like.

Step S102, in the TCI states corresponding to the multiple control resource sets, determine N target TCI states.

In a specific implementation, the determined N target transmission configuration indicator (Transmission Configuration Indicator, TCI) states (states) can be used to determine a reference signal measured by a radio link monitoring (Radio Link Monitoring, RLM), or can be used to determine The reference signal for beam failure detection (BFD) can also be used to determine both the RLM measurement and the reference signal for BFD.

In a specific implementation, the number N of target TCI states for transmission configuration can be pre-configured for the user equipment, and N is delivered to the user equipment through high-layer signaling. The high-layer signaling may be any one of Radio Resource Control (Radio Resource Control, RRC) signaling, MAC signaling, and DCI signaling, or may be a paging message or the like. The N value may also be defaulted by a protocol, or predefined by a protocol, or determined by configuration information, which is not limited.

In this embodiment of the present application, N may be determined by configuration information.

In a specific implementation, the multiple control resource sets corresponding to the high-level configuration parameters may include a first type of control resource set and a second type of control resource set, and the first type of control resource set and the second type of control resource set may be divided according to the search space set period of the control resource set.

For example, the number of multiple control resource sets corresponding to the high-level configuration parameters is 3, which are CORESET#0, CORESET#1 and CORESET#2, wherein: the search space set period corresponding to CORESET#0 is 2 slots (time slot) , the search space set period corresponding to CORESET#1 is 1 slot, and the search space set period corresponding to CORESET#2 is 3 slots. According to the search space set period, the control resource sets with the search space set period not greater than 2 are divided into the first type of search space sets, and the control resource sets with the search space set period greater than 2 are divided into the second type of search space sets.

According to the above division rules, it can be known that the number of centralized control resource sets of the first type of control resources is 2, which are CORESET#0 and CORESET#1 respectively; the number of centralized control resource sets of the second type of control resources is 1, which is CORESET# 2. In other words, the first type of control resource set includes two control resource sets, and the second type of control resource set includes one control resource set.

In a specific implementation, the number of TCI states corresponding to the first type of control resource set is M, and M≥N. At this time, N TCI states may be determined from M TCI states corresponding to the first type of control resource set.

In this embodiment of the present application, the maximum period of the search space set (Search Space set) corresponding to the first type of control resource set is K, and the minimum value of the search space set period corresponding to the second type of control resource set is L, where K≤L .

In this embodiment of the present application, the search space set period corresponding to the first type of control resource set refers to the search space set period corresponding to the control resource set in the first type of control resource set. Correspondingly, the search space set period corresponding to the second type of control resource set refers to the search space set period corresponding to the control resource set in the second type of control resource set.

For example, the control resource set corresponding to the first type of control resource set includes CORESET#0 and CORESET#1, and the search space set period corresponding to CORESET#0 is 2 slots (time slots), and the search space set period corresponding to CORESET#1 is 1 slot , the maximum value of the search space set period corresponding to the first type of control resource set is K=2.

In this embodiment of the present application, when K<L, it means that the search space set period corresponding to any control resource set in the first type of control resource set is smaller than the search space of any control resource set in the second type of control resource set set cycle. For example, in the first type of control resource set, the total number of TCI states corresponding to all control resource sets M=6, and N=4 is determined in advance by the configuration information. In the first type of control resource set, the number of control resource sets whose search empty set cycle is K is 1, and the number of TCI states corresponding to the control resource set corresponding to search space set cycle K is 3.

In the first type of control resource set, if the number of control resource sets corresponding to the search space set period K is 1, then the TCI state corresponding to other control resource sets except the control resource set corresponding to the search space set period K is equal to 1. The total number is less than N; and the total number M of TCI states corresponding to all control resource sets in the first type of control resource set is greater than N. If the number of control resource sets corresponding to the search space set period K is multiple, then the search space set period is the TCI state corresponding to other control resource sets except the control resource set with the largest index value in the control resource set corresponding to the search space set period K The total number is less than N; or, the total number of TCI states corresponding to other control resource sets except the control resource set with the smallest index value in the control resource set corresponding to the search space set period K is less than N.

In the embodiment of the present application, when K=L, in the first type of control resource set, the minimum index value of the control resource set corresponding to the search space set period K is P; in the second type of control resource set, the search space set The maximum index value of the control resource set corresponding to the period L is Q, and P>Q. Or, when K=L, in the first type of control resource set, the minimum index value of the control resource set corresponding to the search space set period K is P; in the second type of control resource set, the search space set period is corresponding to L The maximum index value of the control resource set is Q, and P<Q.

For the first type of control resource set, the number of TCI states corresponding to the control resource set whose search space set period is K and the index value is P is X, where X is a positive integer and N>M-X.

In this embodiment of the present application, from the first type of control resource set, it may be determined that the TCI state corresponding to other control resource sets except the control resource set whose index value is P is the target TCI state. After that, from the control resource set whose index value is P, M-N TCI states are removed according to preset rules, and the remaining TCI states are used as target TCI states. Thus, N target TCI states are obtained.

In a specific application, the preset rule may be to remove the first M-N TCI states in the TCI states corresponding to the control resource set with an index value of P, or remove the last M-N TCI states in the TCI states corresponding to the control resource set with an index value of P TCI state, or remove the top M-N TCI states with the largest identifier value in the TCI state corresponding to the control resource set with the index value P, or remove the top M-N TCI states with the smallest identifier value in the TCI state corresponding to the control resource set with the index value P TCI state.

For example, N=6 is determined in advance by the configuration information, and the total number of TCI states corresponding to all control resource sets in the first type of control resource set is M=8. The first type of control resource set includes CORESET#0, CORESET#1 and CORESET#2. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding two TCI states are TCI state 0 and TCI state 1 respectively; the search space set period corresponding to CORESET#1 is 1 slot, and the corresponding three TCI states are TCI state 2, TCI state 3, TCI state 4; the search space set period corresponding to CORESET#2 is 2 slots, corresponding to 3 TCI states, namely TCI state 5, TCI state 6 and TCI state 7.

In the first type of control resource set, two TCI states corresponding to CORESET#0 and three TCI states corresponding to CORESET#1 are determined as target TCI states. One remaining target TCI state needs to be determined from the search space set corresponding to CORESET#2.

According to the preset rules, from the 3 TCI states corresponding to CORESET#2, remove the first (M-N=2) TCI states with the largest identification, that is, remove TCI state 6 and TCI state 7, and use TCI state 5 as the target TCI state.

To sum up, the determined six target TCI states are: TCI state 0, TCI state 1, TCI state 2, TCI state 3, TCI state 4 and TCI state 5.

For another example, N=2 is determined in advance by the configuration information, and the total number of TCI states corresponding to all control resource sets in the first type of control resource set is M=3. The first type of control resource set includes CORESET#0 and CORESET#1. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding one TCI state is TCI state 0; the search space set period corresponding to CORESET#1 is 2 slots, corresponding to The two TCI states are TCI state 1 and TCI state 2 respectively.

First, determine the TCI state 0 corresponding to CORESET#0 with the smallest search space set as the target TCI state. After that, from CORESET#1, remove the one TCI state with the largest identification value, that is, remove TCI state2, and use TCI state1 as the target TCI state.

To sum up, the two determined target TCI states are TCI state 0 and TCI state 1 in turn.

In a specific implementation, the first type of control resource set may include N control resource sets, and the maximum value of the search space set period corresponding to the N control resource sets is K; the search for the control resource set corresponding to the second type of control resource set The minimum value of the space set period is L; K≤L.

In this embodiment of the present application, when K<L, it means that the search space set period corresponding to any control resource set in the first type of control resource set is smaller than the search space of any control resource set in the second type of control resource set set cycle.

When N target TCI states are determined from the M TCI states corresponding to the first type of control resource set, one TCI state may be selected as the target TCI state from the N control resource sets of the first type of control resource set. If a certain control resource set in the first type of control resource set corresponds to multiple TCI states, one TCI state can be selected as the target TCI state according to any of the following rules: select the first TCI state, select the last TCI state , select the TCI state with the largest identification value, and select the TCI state with the smallest identification value.

For example, N=3 is determined in advance by the configuration information, and the first type of control resource set includes three control resource sets, which are CORESET#0, CORESET#1 and CORESET#2 respectively. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding two TCI states are TCI state 0 and TCI state 1 respectively; the search space set period corresponding to CORESET#1 is 1 slot, and the corresponding three TCI states are TCI state 2, TCI state 3, TCI state 4; the search space set period corresponding to CORESET#2 is 2 slots, corresponding to 3 TCI states, namely TCI state 5, TCI state 6 and TCI state 7.

From each control resource set, select the TCI state with the largest identification value, and then determine the three target TCI states: TCI state 1, TCI state 4, and TCI state 7.

For another example, if N=2 is determined in advance by the configuration information, the first type of control resource set includes two control resource sets, CORESET#0 and CORESET#1, respectively. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding one TCI state is TCI state 0; the search space set period corresponding to CORESET#1 is 2 slots, and the corresponding two TCI states are TCI state 1 and TCI state 2.

From the two control resource sets of the first type of control resource set, determine the TCI state with the largest identification value, then the two determined target TCI states are: TCI state 0 and TCI state 2.

In a specific implementation, the multiple control resource sets corresponding to the high-level configuration parameters may include a third type of control resource set and a fourth type of control resource set. In the embodiment of the present application, any control resource set in the third type of control resource set may correspond to multiple TCI states, and any control resource set in the fourth type of control resource set may correspond to one TCI state.

When determining N target TCI states from TCI states corresponding to multiple control resource sets, N target TCI states may be determined according to at least one of the third type of control resource set and the fourth type of control resource set.

That is to say, when N target TCI states are determined, they can be determined only by the third type of control resource set, only by the fourth type of control resource set, or by both the third type of control resource set and the fourth type of control resource set. Sets are jointly determined.

In the embodiment of the present application, the total number of TCI states corresponding to the control resource set in the third type of control resource set is M, and M≥N. The third type of control resource set may include a first subset and a second subset, where:

The maximum period of the search space set corresponding to the first subset is K, and the minimum period of the search space set corresponding to the second subset is L, K<L; and in the first subset, when the search space set When the number of control resource sets corresponding to the period K is 1, the total number of TCI states corresponding to other control resource sets except the control resource set corresponding to the search space set period K is less than N; when the search space set period is When the number of control resource sets corresponding to K is greater than 1, the total number of TCI states corresponding to other control resource sets except the control resource set with the largest index value in the control resource set corresponding to the search space set period K is less than N; or , when the number of control resource sets corresponding to the search space set period K is greater than 1, the TCI state corresponding to other control resource sets except the control resource set with the smallest index value in the control resource set corresponding to the search space set period K The total number is less than N.

In the embodiment of the present application, when K<L, it means that the search space set period corresponding to any control resource set in the first subset is smaller than the search space set period of any control resource set in the second subset. In the first subset, the total number of TCI states corresponding to other control resource sets except the control resource set corresponding to the search space set period K is less than N; and the total number of TCI states corresponding to all control resource sets in the first subset is The number M is greater than N.

For example, in the first subset, the total number of TCI states corresponding to all control resource sets is M=6, and the pre-configured N=4. In the first subset, the number of control resource sets whose search empty set cycle is K is 1, and the number of TCI states corresponding to control resource sets corresponding to search space set cycle K is 3.

In the embodiment of the present application, when K=L, in the first subset, the minimum index value of the control resource set corresponding to the search space set period K is P; in the second subset, the search space set period is L corresponding to The maximum index value of the control resource set is Q, and P>Q. Or, when K=L, in the first subset, the minimum index value of the control resource set corresponding to the search space set period K is P; in the second subset, the search space set period is the control resource set corresponding to L. The maximum index value is Q, and P<Q.

For the first subset, the number of TCI states corresponding to the control resource set whose search space set period is K and whose index value is P is X, where X is a positive integer and N>M-X. In the first subset, except for the control resource set whose search space set period is K and the index value is P, the total number of TCI states corresponding to other control resource sets is less than N.

In this embodiment of the present application, it may be determined from the first subset that the TCI state corresponding to other control resource sets except the control resource set whose index value is P is the target TCI state. After that, from the control resource set whose index value is P, M-N TCI states are removed according to preset rules, and the remaining TCI states are used as target TCI states. Thus, N target TCI states are obtained. The preset rule may be to remove the first M-N TCI states in the TCI state corresponding to the control resource set whose index value is P, or remove the last M-N TCI states in the TCI state corresponding to the control resource set whose index value is P, or remove the first M-N TCI states. The first M-N TCI states with the largest identification value in the TCI state corresponding to the control resource set with index value P, or the first M-N TCI states with the smallest identification value in the TCI state corresponding to the control resource set with index value P are removed.

For example, N=6 is determined in advance by the configuration information, and the total number of TCI states corresponding to all control resource sets in the first subset is M=8. The first subset includes CORESET#0, CORESET#1, and CORESET#2. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding two TCI states are TCI state 0 and TCI state 1 respectively; the search space set period corresponding to CORESET#1 is 1 slot, and the corresponding three TCI states are TCI state 2, TCI state 3, TCI state 4; the search space set period corresponding to CORESET#2 is 2 slots, corresponding to 3 TCI states, namely TCI state 5, TCI state 6 and TCI state 7.

In the first subset, 2 TCI states corresponding to CORESET#0 and 3 TCI states corresponding to CORESET#1 are determined as target TCI states. One remaining target TCI state needs to be determined from the search space set corresponding to CORESET#2.

For another example, N=2 is determined in advance by the configuration information, the first subset includes CORESET#0 and CORESET#1, and the search space set period corresponding to CORESET#0 is 1 slot, and the corresponding two TCI states are respectively TCI state 0, TCI state state 1; the search space set period corresponding to CORESET#1 is 2 slots, and the corresponding three TCI states are TCI state 2, TCI state 3, and TCI state 4.

Since the control resource set with the smallest search space set is CORESET#0, and the TCI state corresponding to CORESET#0 is exactly 2, the two target TCI states are determined as: TCI state 0 and TCI state 1.

In a specific implementation, if the total number M of TCI states corresponding to the third type of control resource set is less than N, then the TCI states corresponding to the third type of control resource set can be used as the target TCI state, and the fourth type of control resource set can be used as the target TCI state. The TCI states corresponding to N-M control resource sets are collectively selected as the target TCI state. N target TCI states are obtained by selecting M TCI states from the third type of control resource set and N-M TCI states from the fourth type of control resource set.

In this embodiment of the present application, the fourth type of control resource sets includes Y control resource sets. If Y=N-M, the TCI state corresponding to each of the Y control resource sets is determined as the target TCI state. At this time, the target TCI state includes all TCI states corresponding to the third type of control resource set and all TCI states corresponding to the fourth type of control resource set.

For example, N=3 is determined in advance by the configuration information, the third type of control resource set includes CORESET#0, and CORESET#0 corresponds to two TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCI states corresponding to the third type of control resource set is less than 3, and TCI state 0 and TCI state 1 are used as target TCI states. The fourth type of control resource set includes CORESET#1, and CORESET#1 corresponds to one TCI state, which is TCI state 2. Then determine TCI state 2 as the target TCI state. Therefore, the determined three target TCI states are TCI state 0, TCI state 1 and TCI state 2 in turn.

If Y>N-M, it is necessary to select N-M control resource sets from the Y control resource sets, and use the TCI state corresponding to the selected N-M control resource sets as the target TCI state.

In this embodiment of the present application, if the number of control resource sets corresponding to Y control resource sets whose corresponding search space set period is not greater than S is N-M, then N-M control resource sets corresponding to which search space set period is not greater than S are selected; If Y control resource sets are set, the corresponding search space set period is not greater than S, the number of control resource sets corresponding to N is greater than N-M, and the corresponding search space set period is less than S, and the number of control resource sets corresponding to Z is less than N-M, then select N-M-Z search spaces The set period is the control resource set corresponding to S and the control resource sets corresponding to Z search space set periods less than S.

From the Y control resource sets, when selecting N-M-Z search space set periods corresponding to S, the control resource sets corresponding to the first N-M-Z search space set periods with the largest identification value may be selected, or the identification value may be selected. The smallest first N-M-Z search space set period is the control resource set corresponding to S.

For example, N=3 is determined in advance by the configuration information, the third type of control resource set includes CORESET #0, and CORESET #0 corresponds to two TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCI states corresponding to the third type of control resource set is less than 3, and TCI state 0 and TCI state 1 are used as target TCI states. The fourth type of control resource set includes CORESET#1 and CORESET#2. The TCI state corresponding to CORESET#1 is TCI state 2, and the search space set period corresponding to CORESET#1 is 2 slots. The TCI state corresponding to CORESET#2 is TCI state 3, and the search space set period corresponding to CORESET#2 is 2 slots.

In the fourth type of control resource set, the number of control resource sets corresponding to a search space set period not greater than 2 is 2, but N=3, so only one control resource set needs to be selected from the fourth control resource set. Select the control resource set with the largest identification value, that is, select CORESET#2, and then determine the TCI state corresponding to CORESET#2 as the target TCI state.

Therefore, the determined three target TCI states are TCI state 0, TCI state 1 and TCI state 3 in turn.

In a specific implementation, the N target TCI states may also be determined first according to the fourth type of control resource set.

In the embodiment of the present application, if Y=N, the TCI state corresponding to each of the Y control resource sets in the fourth type of control resource set is determined as the target TCI state.

For example, N=3 is determined in advance by configuration information. The fourth type of control resource set includes CORESET#0, CORESET#1, and CORESET#2. The TCI state corresponding to CORESET#0 is TCI state0, the TCI state corresponding to CORESET#1 is TCI state 2, and the TCI state corresponding to CORESET#2 is TCI state 3. The determined three target TCI states are TCI state0, TCI state 2 and TCI state 3 respectively.

If Y>N, N control resource sets can be selected from the Y control resource sets, and the TCI state corresponding to the selected N control resource sets is determined as the target TCI state.

In this embodiment of the present application, if the number of control resource sets corresponding to Y control resource sets with a corresponding search space set period not greater than S is N, then N control resource sets corresponding to search space set periods not greater than S are selected; If there are Y control resource sets, the corresponding search space set period is not greater than S, the corresponding number of control resource sets is greater than N, and the corresponding search space set period is less than S, and the corresponding number of control resource sets Z is less than N, then select N-Z search spaces The set period is the control resource set corresponding to S and the control resource sets corresponding to Z search space set periods less than S.

When selecting the control resource sets corresponding to N-Z search space set periods S from the Y control resource sets, the control resource sets corresponding to the top N-Z search space set periods with the largest identification value can be selected, or the identification value can be selected. The smallest first N-Z search space set period is the control resource set corresponding to S.

For example, N=2 is determined in advance by the configuration information, and the fourth type of control resource set includes CORESET#0, CORESET#1, and CORESET#2, where:

The TCI state corresponding to CORESET#0 is TCI state 0, and the corresponding search space set period is 1 slot;

The TCI state corresponding to CORESET#1 is TCI state 1, and the corresponding search space set period is 2 slots;

The TCI state corresponding to CORESET#2 is TCI state 2, and the search space set period corresponding to CORESET#2 is 2 slots;

In the fourth type of control resource set, the number of control resource sets corresponding to a search space set period not greater than 2 is 3, but N=2, so 2 control resource sets need to be selected from the fourth control resource set. The number of control resource sets whose search space set period is equal to 2 is 2, so it is necessary to select 1 control resource set from them. The preset rule is to select the first control resource set with the largest identification information from the control resource set whose search space set period is equal to 2, then select CORESET#2.

Therefore, the two determined target TCI states are TCI state 0 and TCI state 2 in turn.

If Y<N, the TCI state corresponding to each of the Y control resource sets can be determined as the target TCI state, and N-Y TCI states are selected from the third type of control resource set as the target TCI state.

In a specific implementation, when the determined N target TCI states are used to determine the BFD reference signal, when the N target TCI states are determined from the TCIs corresponding to multiple control resource sets, the corresponding corresponding multiple control resource sets may be obtained first. According to the corresponding identification values of the multiple control resource sets, among the TCI states corresponding to the multiple control resource sets, N target TCI states are determined.

In this embodiment of the present application, if the total number of TCI states corresponding to the control resource set with the identification value not greater than T is N, then the TCI states corresponding to all control resource sets with the identification value not greater than T may be used as N target TCIs state.

For example, N=6 is determined in advance by configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCI state1, the TCI states corresponding to CORESET#1 are TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCI state5. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 3 is 6. Therefore, the determined 6 target TCI states are: TCI state0, TCI state1, TCI state2, TCI state3, TCI state4 and TCI state5.

For another example, N=2 is determined in advance by the configuration information, and the total number of TCI states corresponding to all control resource sets in the first type of control resource set is M=2. The first type of control resource set includes CORESET#0 and CORESET#1. CORESET#0 corresponds to 1 TCI state as TCI state 0; CORESET#1 corresponds to 1 TCI state as TCI state 1. The two determined target TCI states are respectively: TCI state 0 and TCI state 1.

In an embodiment of the present application, if the total number of TCI states corresponding to a control resource set with an identifier value not greater than T is greater than N, and the total number Z of TCI states corresponding to a control resource set with an identifier value less than T is less than N, then N-Z TCI states can be selected from the control resource set with the identifier value T as the target TCI state, and the TCI state corresponding to the control resource set with the identifier value less than T can be used as the target TCI state.

When selecting N-Z TCI states from the control resource set with the identification value T as the target TCI state, the first N-Z TCI states can be selected, the last N-Z TCI states can also be selected, or the first N-Z TCI states with the largest identification value can be selected. Or select the top N-Z TCI states with the smallest identity values.

For example, N=3 is determined in advance by configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCI state1, the TCI states corresponding to CORESET#1 are TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCI state5. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 1 is 5. Since the control resource set whose identification value is less than 1 (that is, CORESET#0) corresponds to 2 TCI states, it is necessary to select the TCI state from CORESET#1. Choose another TCI state as the target TCI state.

Select the first TCI state with the largest identification value from CORESET#1: TCI state4. The final three target TCI states are: TCI state0, TCI state1 and TCI state4.

For example, N=2 is determined in advance by configuration information. The TCI state corresponding to CORESET#0 is TCI state0, the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCI state5. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 1 is 4. Since the control resource set whose identification value is less than 1 (that is, CORESET#0) corresponds to 2 TCI states, it is necessary to obtain the corresponding TCI state from CORESET#1. Choose another TCI state as the target TCI state.

Select the first TCI state with the smallest identification value from CORESET#1: TCI state2. The two final target TCI states are: TCI state0 and TCI state2.

In another embodiment of the present application, if the total number of TCI states corresponding to the control resource set whose identification value is not less than T is greater than N, and the total number Z of TCI states corresponding to the control resource set whose identification value is greater than T is less than N, Then, N-Z TCI states can be selected from the control resource set with the identifier value T as the target TCI state, and the TCI state corresponding to the control resource set with the identifier value greater than T can be used as the target TCI state.

For example, N=3 is determined in advance by configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCI state1, the TCI states corresponding to CORESET#1 are TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCI state5. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not less than 1 is 4. Since the control resource set whose identification value is greater than 1 (that is, CORESET#2) corresponds to 1 TCI state, it is necessary to obtain the corresponding TCI state from CORESET#1. Select 2 more TCI states as target TCI states.

Select the first 2 TCI states with the smallest identification value from CORESET#2: TCI state2, TCI state3. The final three target TCI states are: TCI state2, TCI state3 and TCI state5.

In specific implementation, it is also possible to select the top N control resource sets with the smallest identification value from multiple control resource sets, and select 1 TCI state from the top N control resource sets with the smallest identification value as the target TCI state. If one of the top N control resource sets with the smallest identification value corresponds to multiple TCI states, one TCI state can be selected as the target TCI state, and the selection rule can be any of the following: select the first TCI state, Select the last TCI state, select the TCI state with the largest identification value, and select the TCI state with the smallest identification value.

For example, N=2 is determined in advance by configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCI state1, the TCI states corresponding to CORESET#1 are TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCI state5. The first two control resource sets with the smallest identification value are selected as: CORESET#0, CORESET#1.

Select one TCI state from CORESET#0 and CORESET#1 respectively. Since CORESET#0 and CORESET#1 correspond to multiple TCI states respectively, select TCI state1 from CORESET#0 according to the rule of selecting the TCI state with the largest identification value. Select TCI state4 from CORESET#1, and the two final target TCI states are: TCI state1 and TCI state4.

In a specific implementation, multiple control resource sets may be divided into a third type of control resource set and a fourth type of control resource set, wherein: any control resource set in the third type of control resource set may correspond to multiple TCI states , any control resource set in the fourth type of control resource set corresponds to one TCI state.

In the embodiment of the present application, if the number of TCI states corresponding to the third type of control resource set M≧N, N target TCI states may be determined from the M TCI states corresponding to the third type of control resource set.

Specifically, if the number of TCI states corresponding to the third type of control resource set M=N, the M TCI states corresponding to the third type of control resource set can be used as the target TCI state; if M>N, the Among the M TCI states, N TCI states are selected as the target TCI state.

In the embodiment of the present application, if the total number of TCI states corresponding to the control resource set whose identification value is not greater than T is N in the control resource set of the third type, then all the identification values of the control resource set of the third type are not greater than T. The TCI state corresponding to the control resource set is used as the N target TCI state.

For example, N=6 is determined in advance by configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, among which: the TCI state corresponding to CORESET#0 is TCI state0, TCI state1, the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, CORESET The corresponding TCI states of #2 are TCI state4 and TCI state5. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 3 is 6. Therefore, the determined 6 target TCI states are: TCI state0, TCI state1, TCI state2, TCI state3, TCI state4 and TCI state5.

In an embodiment of the present application, in the third type of control resources, if the total number of TCI states corresponding to a control resource set with an identifier value not greater than T is greater than N, and the TCI state corresponding to a control resource set with an identifier value less than T If the total number Z is less than N, then N-Z TCI states can be selected from the control resource set with the identifier value T as the target TCI state, and the TCI state corresponding to the control resource set with the identifier value less than T can be used as the target TCI state.

For example, N=3 is determined in advance by configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, wherein: the TCI state corresponding to CORESET#0 is TCI state0, TCI state1, and the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, TCI state4, the TCI state corresponding to CORESET#2 is TCI state5 and TCI state6. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 1 is 5. Since the control resource set (that is, CORESET#0) whose identification value is less than 1 corresponds to 2 TCI states, it is necessary to obtain the corresponding TCI state from CORESET#1. Choose another TCI state as the target TCI state.

In another embodiment of the present application, in the third type of control resources, if the total number of TCI states corresponding to a control resource set with an identifier value not less than T is greater than N, and the TCI corresponding to a control resource set with an identifier value greater than T The total number of states Z is less than N, then N-Z TCI states can be selected from the control resource set with the identifier value T as the target TCI state, and the TCI state corresponding to the control resource set with the identifier value greater than T can be used as the target TCI state.

For example, N=3 is determined in advance by configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, wherein: the TCI state corresponding to CORESET#0 is TCI state0, TCI state1, and the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, TCI state4, the TCI state corresponding to CORESET#2 is TCI state5 and TCI state6. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not less than 1 is 4. Since the control resource set whose identification value is greater than 1 (that is, CORESET#2) corresponds to 2 TCI states, it is necessary to obtain the corresponding TCI state from CORESET#1. Choose another TCI state as the target TCI state.

Select the first TCI state with the smallest identification value from CORESET#1: TCI state2. The final three target TCI states are: TCI state2, TCI state5 and TCI state6.

In the embodiment of the present application, the top N-M control resource sets with the largest identification value may be selected from the Y control resource sets, and the TCI state corresponding to the top N-M control resource sets with the largest identification value may be used as the target TCI state; For the first N-M control resource sets with the smallest identification value, the TCI state corresponding to the first N-M control resource sets with the smallest identification value is used as the target TCI state.

For example, N=3 is determined in advance by the configuration information, the third type of control resource set includes CORESET#0, and CORESET#0 corresponds to two TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCI states corresponding to the third type of control resource set is less than 3, and TCI state 0 and TCI state 1 are used as target TCI states. The fourth type of control resource set includes CORESET#1 and CORESET#2.

If the control resource set with the smallest identification value is selected from the fourth type of control resource set, CORESET#1 is selected, and the TCI state corresponding to CORESET#1 is used as the target TCI state.

If the control resource set with the largest identification value is selected from the fourth type of control resource set, CORESET#2 is selected, and the TCI state corresponding to CORESET#2 is used as the target TCI state.

In this embodiment of the present application, the top N control resource sets with the largest identification value may be selected from the Y control resource sets, and the TCI state corresponding to the top N control resource sets with the largest identification value may be used as the target TCI state. Alternatively, it is also possible to select the top N control resource sets with the smallest identification value from the Y control resource sets, and use the TCI state corresponding to the top N control resource sets with the smallest identification value as the target TCI state.

For example, N=2 is determined in advance by the configuration information, and the fourth type of control resource set includes CORESET#0, CORESET#1, and CORESET#2.

If the first two control resource sets with the smallest identification value are selected, the selected control resource sets are CORESET#0 and CORESET#1. The two target TCI states include the respective TCI states corresponding to CORESET#0 and CORESET#1.

If the first two control resource sets with the largest identification values are selected, the selected control resource sets are CORESET#1 and CORESET#. The two target TCI states include the corresponding TCI states of CORESET#1 and CORESET#2.

In a specific implementation, if Y<N, the TCI state corresponding to each of the Y control resource sets can be determined as the target TCI state first, and then N-Y TCI states are selected from the third type of control resource set as the target TCI state.

Specifically, if the number of TCI states corresponding to the control resource set whose identification value is not greater than T is N-Y in the third type of control resource set, then all control resource sets whose identification value is not greater than T in the third type of control resource set can be collected. The corresponding TCI states are used as N-Y target TCI states.

For example, N=6 and Y=4 are determined in advance by configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, among which: the TCI state corresponding to CORESET#0 is TCI state0, TCI state1, the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, CORESET The corresponding TCI states of #2 are TCI state4 and TCI state5. It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 0 is 2. Therefore, in addition to the 4 target TCI states corresponding to the fourth type of control resource set, 2 determined from the third type of control resource set The target TCI states are: TCI state0, TCI state1.

In an embodiment of the present application, in the third type of control resources, if the total number of TCI states corresponding to the control resource set with an identifier value not greater than T is greater than N-Y, and the TCI state corresponding to the control resource set with an identifier value less than T If the total number Z is less than N-Y, then N-Y-Z TCI states can be selected from the control resource set with the identifier value T as the target TCI state, and the TCI state corresponding to the control resource set with the identifier value less than T can be used as the target TCI state.

When selecting N-Y-Z TCI states from the control resource set with the identification value T as the target TCI state, the first N-Y-Z TCI states can be selected, the last N-Y-Z TCI states can also be selected, or the first N-Y-Z TCI states with the largest identification value can be selected. Or select the top N-Y-Z TCI states with the smallest identity values.

For example, N=6 and Y=3 are determined in advance by the configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, wherein: the TCI state corresponding to CORESET#0 is TCI state0, TCI state1, and the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, TCI state4, the TCI state corresponding to CORESET#2 is TCI state5 and TCI state6.

It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not greater than 1 is 5. Since the control resource set (that is, CORESET#0) whose identification value is less than 1 corresponds to 2 TCI states, it is necessary to obtain the corresponding TCI state from CORESET#1. Choose another TCI state as the target TCI state.

In another embodiment of the present application, in the third type of control resource, if the total number of TCI states corresponding to the control resource set with an identifier value not less than T is greater than N-Y, and the TCI corresponding to the control resource set with an identifier value greater than T If the total number of states Z is less than N-Y, then N-Y-Z TCI states can be selected from the control resource set with the identifier value T as the target TCI state, and the TCI state corresponding to the control resource set with the identifier value greater than T can be used as the target TCI state.

It can be seen that the total number of TCI states corresponding to the control resource set whose identification value is not less than 1 is 5. Since the control resource set whose identification value is greater than 1 (that is, CORESET#2) corresponds to 2 TCI states, it is necessary to obtain the corresponding TCI state from CORESET#1. Choose another TCI state as the target TCI state.

Select the first TCI state with the largest identification value from CORESET#1: TCI state4. The final three target TCI states are: TCI state5, TCI state6 and TCI state4.
