[0056] In the prior art, one CORESET can correspond to two TCI states. According to the high-level configuration information, it is determined that the default RLM and / or BFD reference signal needs to be determined through two TCI states. The user equipment receives the configuration information of two CORESETs, where CORESET#0 corresponds to one TCI state and CORESET#1 corresponds to two TCI states. At this time, how the user equipment selects two TCI states is not involved in the existing protocol.

[0057] In an embodiment of the present invention, a high-level configuration parameter is received, and multiple control resource sets and at least one TCI state corresponding to each control resource set are determined according to the high-level configuration parameter; then, N target TCI states are determined from the TCI states corresponding to the multiple control resource sets. From the implementation, it is possible to determine the corresponding N transmission configuration indication states according to the multiple control resource sets.

[0058] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0059] The embodiment of the present invention provides a method for transmitting a configuration indication status indication, referring to Figure 1 , the following is a detailed description through specific steps.

[0060] In a specific implementation, the method for determining the transmission configuration indication state provided in the following steps S101 to S102 may be executed by a baseband chip in the user equipment.

[0061] Step S101: receiving high-level configuration parameters.

[0062] In a specific implementation, the user equipment may receive the high-level configuration parameters sent by the base station. The high-level configuration parameters sent by the base station may include multiple control resource sets (CORESETs), and each control resource set may correspond to at least one TCIstate. After receiving the high-level configuration parameters, the user equipment can know which control resource sets are configured by the base station and the TCI state corresponding to each control resource set.

[0063] In a specific implementation, the base station may send high-level configuration parameters to the user equipment via high-level signaling. The high-level signaling may be a radio resource control (RRC) signaling or a paging message.

[0064] Step S102: determining N target TCI states among the TCI states corresponding to the multiple control resource sets.

[0065] In a specific implementation, the determined N target transmission configuration indication (TCI) states can be used to determine the reference signal for radio link monitoring (RLM) measurement, can also be used to determine the reference signal for beam failure detection (BFD), and can also be used to determine the reference signal for RLM measurement and BFD at the same time.

[0066] In a specific implementation, the number N of transmission configuration target TCI states may be configured in advance for the user equipment, and N may be sent to the user equipment through high-level signaling. The high-level signaling may be any one of Radio Resource Control (RRC) signaling, MAC signaling, and DCI signaling, or may be a paging message, etc. The N value may also be a protocol default, or may be predefined by the protocol, or may be determined by configuration information, without limitation.

[0067] In the embodiment of the present invention, N may be determined by configuration information.

[0068] 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. The number of control resource sets in the first type of control resource set may be one or more, and the number of control resource sets in the second type of control resource set may also be one or more.

[0069] For example, the number of multiple control resource sets corresponding to the high-level configuration parameters is 3, namely CORESET#0, CORESET#1 and CORESET#2, where: the search space set period corresponding to CORESET#0 is 2 slots (time slots), 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 a search space set period not greater than 2 are classified into the first type of search space sets, and the control resource sets with a search space set period greater than 2 are classified into the second type of search space sets.

[0070] According to the above division rules, it can be known that the number of control resource sets in the first type of control resource set is 2, namely CORESET#0 and CORESET#1; the number of control resource sets in the second type of control resource set is 1, namely CORESET#2. In other words, the first type of control resource set includes 2 control resource sets, and the second type of control resource set includes 1 control resource set.

[0071] 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 can be determined from the M TCI states corresponding to the first type of control resource set.

[0072] In the embodiment of the present invention, the maximum value of the search space set period 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, and K≤L.

[0073] In the embodiment of the present invention, 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.

[0074] For example, the control resource sets corresponding to the first type of control resource sets include 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, then the maximum value of the search space set period corresponding to the first type of control resource sets is K=2.

[0075] In an embodiment of the present invention, 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 less than the search space set period of any control resource set in the second type of control resource set. For example, in the first type of control resource set, the total number of TCI states corresponding to all control resource sets is M = 6, and N = 4 is determined in advance by configuration information. In the first type of control resource set, the number of control resource sets with a search space set period of K is 1, and the number of TCI states corresponding to the control resource sets corresponding to the search space set period of K is 3.

[0076] 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, 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 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, 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, 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.

[0077] In the embodiment of the present invention, 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 maximum index value of the control resource set corresponding to the search space set period L is Q, and P>Q. Alternatively, 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 maximum index value of the control resource set corresponding to the search space set period L is Q, and P<Q.

[0078] For the first type of control resource set, the number of TCI states corresponding to the control resource set with a search space set period of K and an index value of P is X, where X is a positive integer and N>MX.

[0079] In an embodiment of the present invention, the TCI states corresponding to the control resource sets other than the control resource set with an index value of P can be determined from the first type of control resource set as the target TCI state. Afterwards, MN TCI states are removed from the control resource set with an index value of P according to a preset rule, and the remaining TCI states are used as the target TCI states. Thus, N target TCI states are obtained.

[0080] In a specific application, the preset rule may be to remove the first MN TCI states in the TCI state corresponding to the control resource set with an index value of P, or to remove the last MN TCI states in the TCI state corresponding to the control resource set with an index value of P, or to remove the first MN TCI states with the largest identification value in the TCI state corresponding to the control resource set with an index value of P, or to remove the first MN TCI states with the smallest identification value in the TCI state corresponding to the control resource set with an index value of P.

[0081] For example, N=6 is determined in advance by the configuration information, and the total number of TCIstates 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 1slot, corresponding to 2 TCI states, namely TCI state 0 and TCIstate 1; the search space set period corresponding to CORESET#1 is 1slot, corresponding to 3 TCI states, namely TCI state2, TCI state3, and TCI state 4; the search space set period corresponding to CORESET#2 is 2slots, corresponding to 3 TCIstates, namely TCI state 5, TCI state 6, and TCI state 7.

[0082] In the first type of control resource set, the two TCI states corresponding to CORESET#0 and the three TCI states corresponding to CORESET#1 are determined as the target TCI states. There is still one target TCI state to be determined from the search space set corresponding to CORESET#2.

[0083] According to the preset rule, the first (MN=2) TCI state with the largest identifier is removed from the three TCI states corresponding to CORESET#2, that is, TCI state 6 and TCI state 7 are removed, and TCI state 5 is used as the target TCIstate.

[0084] In summary, the six target TCI states determined are: TCI state 0, TCI state 1, TCI state 2, TCI state 3, TCI state 4 and TCI state 5.

[0085] For another example, N=2 is determined in advance by the configuration information, and the total number of TCIstates 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 TCI state is TCI state 0; the search space set period corresponding to CORESET#1 is 2 slots, and the corresponding 2 TCI states are TCI state 1 and TCI state 2 respectively.

[0086] First, TCI state 0 corresponding to CORESET#0 with the smallest search space set is determined as the target TCI state. Then, the TCI state with the largest identification value is removed from CORESET#1, that is, TCI state2 is removed, and TCI state1 is used as the target TCI state.

[0087] In summary, the two target TCI states determined are TCI state 0 and TCI state 1 respectively.

[0088] 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 minimum value of the search space set period of the control resource set corresponding to the second type of control resource set is L; K≤L.

[0089] In the embodiment of the present invention, 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 set period of any control resource set in the second type of control resource set.

[0090] In the embodiment of the present invention, 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 maximum index value of the control resource set corresponding to the search space set period L is Q, and P>Q. Alternatively, 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 maximum index value of the control resource set corresponding to the search space set period L is Q, and P<Q.

[0091] When determining N target TCI states from the M TCI states corresponding to the first type of control resource set, one TCI state can be selected from each of the N control resource sets of the first type of control resource set as the target TCI state. If a 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: selecting the first TCI state, selecting the last TCI state, selecting the TCI state with the largest identification value, and selecting the TCI state with the smallest identification value.

[0092] For example, N=3 is determined in advance by the configuration information, and the first type of control resource set includes 3 control resource sets, namely CORESET#0, CORESET#1 and CORESET#2. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding 2 TCI states are TCI state 0 and TCI state 1; the search space set period corresponding to CORESET#1 is 1 slot, and the corresponding 3 TCI states are TCI state 2, TCI state 3, and TCI state 4; the search space set period corresponding to CORESET#2 is 2 slots, and the corresponding 3 TCI states are TCI state 5, TCI state 6, and TCI state 7.

[0093] From each control resource set, the TCI state with the largest identification value is selected, and the three target TCIstates determined are: TCI state 1, TCI state 4 and TCI state 7.

[0094] For another example, N=2 is determined in advance by configuration information, and the first type of control resource set includes two control resource sets, namely CORESET#0 and CORESET#1. The search space set period corresponding to CORESET#0 is 1 slot, and the corresponding 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 TCIstate 1 and TCI state 2.

[0095] The TCI state with the largest identification value is determined from the two control resource sets of the first type of control resource set respectively, and the two target TCI states determined are: TCI state 0 and TCI state 2 respectively.

[0096] 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 an embodiment of the present invention, 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.

[0097] When determining N target TCI states from TCI states corresponding to multiple control resource sets, the 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.

[0098] That is to say, when determining the N target TCI states, they may be determined only by the third type of control resource set, or only by the fourth type of control resource set, or jointly by the third type of control resource set and the fourth type of control resource set.

[0099] In the embodiment of the present invention, the total number of TCI states corresponding to the control resource sets 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, wherein:

[0100] The maximum value of the search space set period corresponding to the first subset is K, and the minimum value of the search space set period corresponding to the second subset is L, K<L; and in the first subset, when the number of control resource sets corresponding to the search space set period K is 1, the total number of TCIstates 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 number of control resource sets corresponding to the search space set period 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 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.

[0101] In the embodiment of the present invention, when K<L, it means that the search space set period corresponding to any control resource set in the first subset is less 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 M of TCI states corresponding to all control resource sets in the first subset is greater than N.

[0102] For example, in the first subset, the total number of TCI states corresponding to all control resource sets is M = 6, and the preconfigured N = 4. In the first subset, the number of control resource sets with a search space period of K is 1, and the number of TCI states corresponding to control resource sets with a search space period of K is 3.

[0103] In the embodiment of the present invention, 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 maximum index value of the control resource set corresponding to the search space set period L is Q, and P>Q. Alternatively, 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 maximum index value of the control resource set corresponding to the search space set period L is Q, and P<Q.

[0104] For the first subset, the number of TCIstates corresponding to the control resource set with a search space set period of K and an index value of P is X, where X is a positive integer and N>MX. In the first subset, except for the control resource set with a search space set period of K and an index value of P, the total number of TCI states corresponding to other control resource sets is less than N.

[0105] In an embodiment of the present invention, the TCI state corresponding to other control resource sets except the control resource set with an index value of P can be determined from the first subset as the target TCI state. Afterwards, MN TCI states are removed from the control resource set with an index value of P according to a preset rule, and the remaining TCI states are used as the target TCI state. Thus, N target TCI states are obtained. The preset rule may be to remove the first MN TCI states in the TCI state corresponding to the control resource set with an index value of P, or to remove the last MN TCI states in the TCI state corresponding to the control resource set with an index value of P, or to remove the first MN TCI states with the largest identification value in the TCI state corresponding to the control resource set with an index value of P, or to remove the first MN TCI states with the smallest identification value in the TCI state corresponding to the control resource set with an index value of P.

[0106] For example, N=6 is determined in advance by the configuration information, and the total number of TCIstates 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 1slot, corresponding to 2 TCIstates, namely TCI state 0 and TCI state 1; the search space set period corresponding to CORESET#1 is 1slot, corresponding to 3 TCI states, namely TCI state 2, TCI state 3, and TCI state 4; the search space set period corresponding to CORESET#2 is 2slots, corresponding to 3 TCI states, namely TCI state 5, TCIstate 6, and TCI state 7.

[0107] In the first subset, the two TCI states corresponding to CORESET#0 and the three TCI states corresponding to CORESET#1 are determined as the target TCI states. There is still one target TCI state to be determined from the search space set corresponding to CORESET#2.

[0108] According to the preset rule, the first (MN=2) TCI state with the largest identifier is removed from the three TCI states corresponding to CORESET#2, that is, TCI state 6 and TCI state 7 are removed, and TCI state 5 is used as the target TCIstate.

[0109] In summary, the six target TCI states determined are: TCI state 0, TCI state 1, TCI state 2, TCI state 3, TCI state 4 and TCI state 5.

[0110] For 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 1slot, and the corresponding 2 TCI states are TCI state 0 and TCIstate 1 respectively; the search space set period corresponding to CORESET#1 is 2slots, and the corresponding 3 TCI states are TCI state2, TCI state 3, and TCI state 4 respectively.

[0111] 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 to be: TCI state 0 and TCIstate 1.

[0112] 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, all TCI states corresponding to the third type of control resource set can be used as target TCI states, and the TCI states corresponding to NM control resource sets are selected from the fourth type of control resource set as target TCI states. By selecting M TCI states from the third type of control resource set and NM TCI states from the fourth type of control resource set, N target TCI states are obtained.

[0113] In an embodiment of the present invention, the fourth type of control resource set includes Y control resource sets. If Y=NM, 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.

[0114] For example, N=3 is determined in advance by the configuration information, and the third type of control resource set includes CORESET#0, and CORESET#0 corresponds to 2 TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCIstates 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 1 TCI state, which is TCI state 2. Then TCI state 2 is determined as the target TCI state. Therefore, the three target TCI states determined are TCI state 0, TCI state 1, and TCIstate 2, respectively.

[0115] If Y>NM, then NM control resource sets need to be selected from the Y control resource sets, and the TCI states corresponding to the selected NM control resource sets are used as the target TCI state.

[0116] In an embodiment of the present invention, if among Y control resource sets, the number of control resource sets corresponding to the search space set period not greater than S is NM, then NM control resource sets corresponding to the search space set period not greater than S are selected; if among Y control resource sets, the number of control resource sets corresponding to the search space set period not greater than S is greater than NM, and the number of control resource sets corresponding to the corresponding search space set period is less than S and Z is less than NM, then control resource sets corresponding to NMZ search space set periods and control resource sets corresponding to Z search space set periods less than S are selected.

[0117] When selecting a control resource set corresponding to NMZ search space set periods S from Y control resource sets, you can select a control resource set corresponding to the first NMZ search space set period S with the largest identification value, or you can select a control resource set corresponding to the first NMZ search space set period S with the smallest identification value.

[0118] For example, N=3 is determined in advance by the configuration information, and the third type of control resource set includes CORESET#0, and CORESET#0 corresponds to 2 TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCIstates 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 2slot. The TCI state corresponding to CORESET#2 is TCI state 3, and the search space set period corresponding to CORESET#2 is 2slot.

[0119] In the fourth type of control resource set, the number of control resource sets corresponding to the 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. The control resource set with the largest identification value is selected, that is, CORESET#2 is selected, and then the TCI state corresponding to CORESET#2 is determined as the target TCI state.

[0120] Therefore, the three target TCI states determined are TCI state 0, TCI state 1, and TCI state 3.

[0121] In a specific implementation, N target TCI states may also be determined first according to the fourth type of control resource set.

[0122] In the embodiment of the present invention, if Y=N, then 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.

[0123] 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 TCIstate 2, and the TCI state corresponding to CORESET#2 is TCI state 3. The three determined target TCI states are TCIstate0, TCI state 2, and TCI state 3.

[0124] If Y>N, N control resource sets may be selected from the Y control resource sets, and the TCI states corresponding to the selected N control resource sets may be determined as the target TCI state.

[0125] In an embodiment of the present invention, if among Y control resource sets, the number of control resource sets corresponding to the search space set period not greater than S is N, then N control resource sets corresponding to the search space set period not greater than S are selected; if among Y control resource sets, the number of control resource sets corresponding to the search space set period not greater than S is greater than N, and the number of control resource sets corresponding to the corresponding search space set period is less than S is Z is less than N, then control resource sets corresponding to NZ search space set periods S and control resource sets corresponding to Z search space set periods less than S are selected.

[0126] When selecting control resource sets corresponding to NZ search space set periods S from Y control resource sets, you can select the control resource sets corresponding to the first NZ search space set periods S with the largest identification values, or you can select the control resource sets corresponding to the first NZ search space set periods S with the smallest identification values.

[0127] For example, N=2 is determined in advance by configuration information, and the fourth type of control resource set includes CORESET#0, CORESET#1, and CORESET#2, where:

[0128] The TCI state corresponding to CORESET#0 is TCI state 0, and its corresponding search space set period is 1 slot;

[0129] The TCI state corresponding to CORESET#1 is TCI state 1, and its corresponding search space set period is 2 slots;

[0130] The TCI state corresponding to CORESET#2 is TCI state 2, and the search space set period corresponding to CORESET#2 is 2 slots;

[0131] In the fourth type of control resource set, the number of control resource sets corresponding to the 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 with a search space set period equal to 2 is 2, so 1 control resource set needs to be selected from them. The preset rule is to select the first control resource set with the largest identification information from the control resource set with a search space set period equal to 2, so CORESET#2 is selected.

[0132] Therefore, the two target TCI states determined are TCI state 0 and TCI state 2 respectively.

[0133] If Y<N, then the TCI states corresponding to the Y control resource sets can be determined as the target TCI states, and NY TCI states are selected from the third type of control resource sets as the target TCI states.

[0134] In a specific implementation, when the determined N target TCI states are used to determine the BFD reference signal, when determining the N target TCI states from the TCIs corresponding to multiple control resource sets, the identification values ​​corresponding to the multiple control resource sets can be first obtained; according to the identification values ​​corresponding to the multiple control resource sets, the N target TCI states are determined in the TCI states corresponding to the multiple control resource sets.

[0135] In this embodiment of the present invention, if the total number of TCI states corresponding to control resource sets whose identification values ​​are not greater than T is N, the TCI states corresponding to all control resource sets whose identification values ​​are not greater than T may be used as N target TCI states.

[0136] For example, N=6 is determined in advance by the configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCIstate1, 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 sets whose identification values ​​are not greater than 3 is 6, so the 6 target TCI states determined are: TCI state0, TCI state1, TCI state2, TCIstate3, TCI state4, and TCI state5.

[0137] For another example, N=2 is determined in advance by the configuration information, and the total number of TCIstates 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 one TCIstate, TCI state 0; CORESET#1 corresponds to one TCI state, TCI state 1. Then the two target TCIstates determined are: TCI state0 and TCI state 1.

[0138] In one embodiment of the present invention, if the total number of TCI states corresponding to the control resource sets whose identification values ​​are not greater than T is greater than N, and the total number of TCI states Z corresponding to the control resource sets whose identification values ​​are less than T is less than N, then NZ TCI states can be selected from the control resource sets whose identification value is T as the target TCI state, and the TCI state corresponding to the control resource sets whose identification value is less than T is used as the target TCI state.

[0139] When selecting NZ TCI states as target TCI states from a control resource set with an identification value of T, the first NZ TCI states or the last NZ TCI states may be selected, or the first NZ TCI states with the largest identification value may be selected, or the first NZ TCI states with the smallest identification value may be selected.

[0140] For example, N=3 is determined in advance by the configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCIstate1, 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 another TCI state from CORESET#1 as the target TCI state.

[0141] The first TCI state with the largest identification value is selected from CORESET#1 as TCI state 4. The three target TCI states finally determined are TCI state 0, TCI state 1, and TCI state 4.

[0142] For example, N=2 is determined in advance by the configuration information. The TCI state corresponding to CORESET#0 is TCI state0, the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, 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 with an identification value not greater than 1 is 4. Since the control resource set with an identification value less than 1 (that is, CORESET#0) corresponds to 2 TCI states, it is necessary to select another TCI state from CORESET#1 as the target TCI state.

[0143] The first TCI state with the smallest identification value is selected from CORESET#1 as TCI state 2. The two target TCI states finally determined are TCI state 0 and TCI state 2.

[0144] In another embodiment of the present invention, if the total number of TCI states corresponding to the control resource sets whose identification value is not less than T is greater than N, and the total number of TCI states Z corresponding to the control resource sets whose identification value is greater than T is less than N, then NZ TCI states can be selected from the control resource sets whose identification value is T as the target TCI state, and the TCI state corresponding to the control resource sets whose identification value is greater than T is used as the target TCI state.

[0145] When selecting NZ TCI states as target TCI states from a control resource set with an identification value of T, the first NZ TCI states or the last NZ TCI states may be selected, or the first NZ TCI states with the largest identification value may be selected, or the first NZ TCI states with the smallest identification value may be selected.

[0146] For example, N=3 is determined in advance by the configuration information. The TCI states corresponding to CORESET#0 are TCI state0 and TCIstate1, 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 with an identification value not less than 1 is 4. Since the control resource set with an identification value greater than 1 (that is, CORESET#2) corresponds to 1 TCI state, it is necessary to select 2 more TCI states from CORESET#1 as the target TCI state.

[0147] The first two TCI states with the smallest identification value are selected from CORESET#2 as TCI state 2 and TCI state 3. The three target TCI states finally determined are TCI state 2, TCI state 3, and TCI state 5.

[0148] In a specific implementation, the first N control resource sets with the smallest identification value may also be selected from multiple control resource sets, and one TCI state may be selected from each of the first N control resource sets with the smallest identification value as the target TCI state. If one of the first N control resource sets with the smallest identification value corresponds to multiple TCI states, one TCI state may be selected from them as the target TCI state, and the selection rule may be any one of the following: selecting the first TCI state, selecting the last TCI state, selecting the TCI state with the largest identification value, or selecting the TCI state with the smallest identification value.

[0149] 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 and CORESET#1.

[0150] Select one TCI state from CORESET#0 and CORESET#1 respectively. Since CORESET#0 and CORESET#1 correspond to multiple TCI states respectively, according to the rule of selecting the TCI state with the largest identification value, select TCIstate1 from CORESET#0 and select TCIstate4 from CORESET#1. The two target TCI states finally determined are: TCIstate1 and TCIstate4.

[0151] In a specific implementation, multiple control resource sets can be divided into a third category of control resource sets and a fourth category of control resource sets, wherein: any control resource set in the third category of control resource sets corresponds to multiple TCI states, and any control resource set in the fourth category of control resource sets corresponds to one TCI state.

[0152] When determining N target TCI states from TCI states corresponding to multiple control resource sets, the 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.

[0153] That is to say, when determining the N target TCI states, they may be determined only by the third type of control resource set, or only by the fourth type of control resource set, or jointly by the third type of control resource set and the fourth type of control resource set.

[0154] In the embodiment of the present invention, if the number of TCI states corresponding to the third type of control resource set is M≥N, N target TCI states may be determined from the M TCI states corresponding to the third type of control resource set.

[0155] 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, N TCI states need to be selected from the M TCI states as the target TCI state.

[0156] In an embodiment of the present invention, if the total number of TCI states corresponding to control resource sets whose identification values ​​are not greater than T in the third category of control resource sets is N, then the TCI states corresponding to all control resource sets whose identification values ​​are not greater than T in the third category of control resource sets can be used as N target TCI states.

[0157] For example, N=6 is determined in advance by the configuration information. The third type of control resource set includes CORESET#0, CORESET#1, and CORESET#2, where: the TCI state corresponding to CORESET#0 is TCI state0 and TCI state1, the TCI state corresponding to CORESET#1 is TCI state2 and TCI state3, and the TCI state corresponding to CORESET#2 is TCI state4 and TCIstate5. It can be seen that the total number of TCI states corresponding to the control resource set with an identification value not greater than 3 is 6, so the 6 target TCI states determined are: TCI state0, TCI state1, TCI state2, TCI state3, TCI state4, and TCI state5.

[0158] In one embodiment of the present invention, in the third category of control resources, if the total number of TCI states corresponding to the control resource set whose identification value is not greater than T is greater than N, and the total number of TCI states Z corresponding to the control resource set whose identification value is less than T is less than N, then NZ TCI states can be selected from the control resource set whose identification value is T as the target TCI state, and the TCI state corresponding to the control resource set whose identification value is less than T is used as the target TCI state.

[0159] When selecting NZ TCI states as target TCI states from a control resource set with an identification value of T, the first NZ TCI states or the last NZ TCI states may be selected, or the first NZ TCI states with the largest identification value may be selected, or the first NZ TCI states with the smallest identification value may be selected.

[0160] For example, N=3 is determined in advance by the configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, where: the TCI state corresponding to CORESET#0 is TCI state0 and TCI state1, the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCIstate5 and TCI state6. It can be seen that the total number of TCI states corresponding to the control resource set with an identification value not greater than 1 is 5. Since the control resource set with an identification value less than 1 (that is, CORESET#0) corresponds to 2 TCI states, it is necessary to select another TCI state from CORESET#1 as the target TCI state.

[0161] The first TCI state with the largest identification value is selected from CORESET#1 as TCI state 4. The three target TCI states finally determined are TCI state 0, TCI state 1, and TCI state 4.

[0162] In another embodiment of the present invention, in the third category of control resources, 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 of TCI states Z corresponding to the control resource set whose identification value is greater than T is less than N, then NZ TCI states can be selected from the control resource set whose identification value is T as the target TCI state, and the TCI state corresponding to the control resource set whose identification value is greater than T is used as the target TCI state.

[0163] When selecting NZ TCI states as target TCI states from a control resource set with an identification value of T, the first NZ TCI states or the last NZ TCI states may be selected, or the first NZ TCI states with the largest identification value may be selected, or the first NZ TCI states with the smallest identification value may be selected.

[0164] For example, N=3 is determined in advance by the configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, where: the TCI state corresponding to CORESET#0 is TCI state0 and TCI state1, the TCI state corresponding to CORESET#1 is TCI state2, TCI state3, and TCI state4, and the TCI state corresponding to CORESET#2 is TCIstate5 and TCI state6. It can be seen that the total number of TCI states corresponding to the control resource set with an identification value not less than 1 is 4. Since the control resource set with an identification value greater than 1 (that is, CORESET#2) corresponds to 2 TCI states, it is necessary to select another TCI state from CORESET#1 as the target TCI state.

[0165] The first TCI state with the smallest identification value is selected from CORESET#1 as TCI state 2. The three target TCI states finally determined are TCI state 2, TCI state 5, and TCI state 6.

[0166] 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, all TCI states corresponding to the third type of control resource set can be used as target TCI states, and the TCI states corresponding to NM control resource sets are selected from the fourth type of control resource set as target TCI states. By selecting M TCI states from the third type of control resource set and NM TCI states from the fourth type of control resource set, N target TCI states are obtained.

[0167] In an embodiment of the present invention, the fourth type of control resource set includes Y control resource sets. If Y=NM, 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.

[0168] For example, N=3 is determined in advance by the configuration information, and the third type of control resource set includes CORESET#0, and CORESET#0 corresponds to 2 TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCIstates 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 1 TCI state, which is TCI state 2. Then TCI state 2 is determined as the target TCI state. Therefore, the three target TCI states determined are TCI state 0, TCI state 1, and TCIstate 2, respectively.

[0169] If Y>NM, then NM control resource sets need to be selected from the Y control resource sets, and the TCI states corresponding to the selected NM control resource sets are used as the target TCI state.

[0170] In an embodiment of the present invention, the first NM control resource sets with the largest identification value can be selected from Y control resource sets, and the TCI state corresponding to the first NM control resource sets with the largest identification value can be used as the target TCI state; or, the first NM control resource sets with the smallest identification value can be selected, and the TCI state corresponding to the first NM control resource sets with the smallest identification value can be used as the target TCI state.

[0171] 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 2 TCI states, namely TCI state 0 and TCI state 1. Therefore, the total number of TCIstates 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.

[0172] 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.

[0173] 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.

[0174] In a specific implementation, N target TCI states may also be determined first according to the fourth type of control resource set.

[0175] In the embodiment of the present invention, if Y=N, then 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.

[0176] 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 TCIstate 2, and the TCI state corresponding to CORESET#2 is TCI state 3. The three determined target TCI states are TCIstate0, TCI state 2, and TCI state 3.

[0177] If Y>N, N control resource sets may be selected from the Y control resource sets, and the TCI states corresponding to the selected N control resource sets may be determined as the target TCI state.

[0178] In an embodiment of the present invention, the first 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 first N control resource sets with the largest identification value may be used as the target TCI state. Alternatively, the first N control resource sets with the smallest identification value may be selected from the Y control resource sets, and the TCI state corresponding to the first N control resource sets with the smallest identification value may be used as the target TCI state.

[0179] For example, N=2 is determined in advance by configuration information, and the fourth type of control resource sets includes CORESET#0, CORESET#1, and CORESET#2.

[0180] If the first two control resource sets with the smallest identification values ​​are selected, the selected control resource sets are CORESET#0 and CORESET#1. The two target TCI states include the TCI states corresponding to CORESET#0 and CORESET#1, respectively.

[0181] 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 TCI states corresponding to CORESET#1 and CORESET#2, respectively.

[0182] In a specific implementation, if Y<N, then the TCI states corresponding to the Y control resource sets may be first determined as the target TCI states, and then NY TCI states may be selected from the third type of control resource set as the target TCI states.

[0183] Specifically, if the number of TCIstates corresponding to control resource sets with identification values ​​not greater than T in the third category of control resource sets is NY, then the TCI states corresponding to all control resource sets with identification values ​​not greater than T in the third category of control resource sets can be used as NY target TCI states.

[0184] For example, N=6, Y=4 are determined in advance by the configuration information. The third type of control resource set includes CORESET#0, CORESET#1 and CORESET#2, where: the TCI state corresponding to CORESET#0 is TCI state0 and TCI state1, the TCI state corresponding to CORESET#1 is TCI state2 and TCI state3, and the TCI state corresponding to CORESET#2 is TCIstate4 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, the 2 target TCI states determined from the third type of control resource set are: TCI state0 and TCI state1.

[0185] In one embodiment of the present invention, in the third category of control resources, if the total number of TCI states corresponding to the control resource set whose identification value is not greater than T is greater than NY, and the total number of TCI states Z corresponding to the control resource set whose identification value is less than T is less than NY, then NYZ TCI states can be selected from the control resource set whose identification value is T as the target TCI state, and the TCI state corresponding to the control resource set whose identification value is less than T is used as the target TCI state.

[0186] When selecting NYZ TCI states as target TCI states from a control resource set with an identification value of T, the first NYZ TCI states, the last NYZ TCI states, the first NYZ TCI states with the largest identification value, or the first NYZ TCI states with the smallest identification value may be selected.

[0187] For example, N=6, Y=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 and TCI state1, 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 and TCI state6.

[0188] It can be seen that the total number of TCI states corresponding to the control resource set with an identification value not greater than 1 is 5. Since the control resource set with an identification value less than 1 (that is, CORESET#0) corresponds to 2 TCI states, it is necessary to select another TCI state from CORESET#1 as the target TCI state.

[0189] The first TCI state with the largest identification value is selected from CORESET#1 as TCI state 4. The three target TCI states finally determined are TCI state 0, TCI state 1, and TCI state 4.

[0190] In another embodiment of the present invention, in the third category of control resources, if the total number of TCI states corresponding to the control resource set whose identification value is not less than T is greater than NY, and the total number of TCI states Z corresponding to the control resource set whose identification value is greater than T is less than NY, then NYZ TCI states can be selected from the control resource set whose identification value is T as the target TCI state, and the TCI state corresponding to the control resource set whose identification value is greater than T is used as the target TCI state.

[0191] When selecting NYZ TCI states as target TCI states from a control resource set with an identification value of T, the first NYZ TCI states, the last NYZ TCI states, the first NYZ TCI states with the largest identification value, or the first NYZ TCI states with the smallest identification value may be selected.

[0192] For example, N=6, Y=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 and TCI state1, 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 and TCI state6.

[0193] It can be seen that the total number of TCI states corresponding to the control resource set with an identification value not less than 1 is 5. Since the control resource set with an identification value greater than 1 (that is, CORESET#2) corresponds to 2 TCI states, it is necessary to select another TCI state from CORESET#1 as the target TCI state.

[0194] The first TCI state with the largest identification value is selected from CORESET#1 as TCI state 4. The three target TCI states finally determined are TCI state 5, TCI state 6 and TCI state 4.
