[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The information indication method, apparatus, communication device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0026] See also Figure 1 , Figure 1 is a flowchart of an information indication method provided by an embodiment of the present application, the method is applied to a terminal, such as Figure 1 As shown, the method comprises the following steps:

[0027] Step 11: The terminal receives first indication information, where the first indication information is used to indicate a first association relationship between X carrier lists and Y CORESET pool indexes.

[0028] Here, X and Y are integers greater than or equal to 1. For example, X and Y are both equal to 2; or, X is equal to 2, and Y is equal to 3. A control resource set pool index CORESET pool index may correspond to a serving cell, and different CORESET pool indexes may correspond to different TCI states, that is, there is a corresponding relationship between the CORESET pool index and the TCI state.

[0029] The CORESET pool index may be abbreviated as CPI.

[0030] In this embodiment, after receiving the first indication information, the terminal may update the association relationship between the X carrier lists and the Y CORESET pool indexes according to the first association relationship, and then implement TCI update of the CC in the X carrier lists according to the association relationship.

[0031] Optionally, the carrier CC in the X carrier list may operate in a single-station transmission mode, such as a single-transmission and receiving point (S-TRP) scenario, or in a multi-station transmission mode, such as a multi-transmission and receiving point (M-TRP) scenario.

[0032] Optionally, before receiving the first indication information, the terminal may receive configuration information, such as receiving configuration information from a network side device, where the configuration information is used to configure an association relationship between X carrier lists and Y CORESET pool indexes, which is different from the above-mentioned first association relationship.

[0033] Optionally, the terminal may receive a first indication message sent by a network side device, that is, the network side device indicates a first association relationship between X carrier lists and Y CORESET pool indexes. For example, in an S-TRP scenario and / or an M-TRP scenario, the serving cell may first configure an association relationship between X carrier lists and Y CORESET pool indexes through radio resource control (RRC) signaling, and then update the association relationship between X carrier lists and Y CORESET pool indexes through a media access control control element (MAC CE) or downlink control information (DCI). This MAC CE or DCII may come from any cell.

[0034] Optionally, the updating condition of the association relationship between the X carrier lists and the Y CORESET pool indexes includes but is not limited to at least one of the following: 1) resource utilization; 2) channel quality; 3) cell energy saving state.

[0035] In the embodiment of the present application, in order to indicate the association relationship between X carrier lists and Y CORESET pool indexes, the first indication information may use X*Y bits, or other number of bits. For each bit, it may be '1' for association, '0' for non-association; or '1' for non-association, '0' for association.

[0036] For example, assuming that X*Y bits are used, and '1' indicates association, and '0' indicates non-association, the indication content of the first indication information may be as shown in the following Table 1:

[0037] Table 1

[0038]

[0039] Optionally, the terminal may receive the first indication information through at least one of the following:

[0040] RRC signaling, MAC CE, DCI.

[0041] For example, if MAC CE is used, a reserved bit or a newly added bit in the unified TCI activation / deactivation field of MAC CE may be used to carry the first indication information to indicate a first association relationship between the X carrier lists and the Y CORESET pool indexes. Alternatively, if DCI is used, a newly added bit in the DCI may be used to carry the first indication information to indicate a first association relationship between the X carrier lists and the Y CORESET pool indexes.

[0042] In some embodiments, assuming that MAC CE activates 8 groups of TCI states, in order to increase the flexibility of indication, each group of TCI states may include 1 TCI state {TCI state ID}, or 2 TCI states {1 st TCI stateID, 2 nd TCI state ID}, etc.; and the 3 bits in the transmission configuration indication field of DCI can be used to select one of the 8 groups of TCI states activated by MAC CE to indicate.

[0043] Optionally, if the X is equal to 2, the Y is equal to 2, and the two carrier lists include carrier list 1 and carrier list 2, and the two CORESET pool indexes include CORESET pool index 0 and CORESET pool index 1, then the first association relationship may include any one of the following:

[0044] 1) Carrier list 1 is associated with CORESET pool index 0, and carrier list 2 is associated with CORESET pool index 1;

[0045] 2) Carrier list 1 is associated with CORESET pool index 1, and carrier list 2 is associated with CORESET pool index 0.

[0046] Optionally, when both X and Y are equal to 2, and the two carrier lists include carrier list 1 and carrier list 2, and the two CORESET pool indexes include CORESET pool index 0 and CORESET pool index 1, if the first indication information uses 1 bit, the indication of the first indication information may include any one of the following:

[0047] (1) When the value of the first indication information is 1, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 0, and the carrier list 2 is associated with the CORESET pool index 1; or, when the value of the first indication information is 0, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 1, and the carrier list 2 is associated with the CORESET pool index 0;

[0048] (2) When the value of the first indication information is 0, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 0, and the carrier list 2 is associated with the CORESET pool index 1; or, when the value of the first indication information is 1, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 1, and the carrier list 2 is associated with the CORESET pool index 0.

[0049] Optionally, in the first association relationship, when at least one carrier in the first carrier list operates in single-station transmission mode, the first carrier list is associated with at most one CORESET pool index, and the first carrier list is one carrier list in the X carrier lists. For example, for one carrier list in the X carrier lists, if at least one carrier in the one carrier list operates in S-TRP mode, the one carrier list is associated with at most one CORESETpool index.

[0050] Optionally, in the first association relationship, when all carriers in the second carrier list operate in multi-station transmission mode, the second carrier list is associated with at least 2 CORESET pool indexes, and the second carrier list is a carrier list in the X carrier lists. For example, for a carrier list in the X carrier lists, if all carriers in the one carrier list operate in M-TRP mode, the one carrier list is associated with at least 2 CORESET poolindexes to achieve multi-station coordinated transmission.

[0051] Optionally, when the third carrier list in the X carrier lists is associated with the first CORESET pool index, if the TCI state of the first carrier in the third carrier list is updated, the first carrier may be any carrier in the third carrier list, then the TCI states corresponding to the first CORESET pool index of all carriers in the third carrier list are updated consistently; or, if the TCI state corresponding to the second CORESETpool index of the second carrier in the third carrier list is updated, the first carrier may be any carrier in the third carrier list, and the second CORESET pool index is different from the first CORESET pool index, then the TCI states of other carriers in the third carrier list except the second carrier are not updated. In this way, it can be ensured that the carriers in the third carrier list with the same TCI state are updated consistently.

[0052] Optionally, when the fourth carrier list in the X carrier lists is associated with the third CORESET pool index, if the TCI state of the carrier in the single-station transmission mode (such as the S-TRP scenario) in the fourth carrier list is updated, the TCI state corresponding to the third CORESET poolindex of the carrier in the multi-station transmission mode (such as the M-TRP scenario) in the fourth carrier list is consistently updated; or, if the TCI state corresponding to the third CORESET pool index of the carrier in the multi-station transmission mode (such as the M-TRP scenario) in the fourth carrier list is updated, the TCI state of the carrier in the single-station transmission mode (such as the S-TRP scenario) in the fourth carrier list is consistently updated; or, if the TCI state corresponding to the fourth CORESET pool index of the carrier in the multi-station transmission mode (such as the M-TRP scenario) in the fourth carrier list is updated, and the fourth CORESET pool index is different from the third CORESET pool index, the TCI state of the carrier in the single-station transmission mode (such as the S-TRP scenario) in the fourth carrier list is not updated.

[0053] For example, assuming that CC list 1 is associated with CORESET pool index = 0, then: if the TCI of the CC of the S-TRP in CC list 1 is updated, the TCI corresponding to the CORESET pool index = 0 of the CC of the M-TRP in CC list 1 is updated accordingly; or, if the TCI corresponding to the CORESET pool index = 0 of the CC of the M-TRP in CC list 1 is updated, the TCI of the CC of the S-TRP in CClist 1 is updated accordingly; conversely, if the TCI corresponding to the CORESET poolindex≠0 of the CC of the M-TRP in CC list 1 is updated, the TCI of the CC of the S-TRP in CC list 1 is not updated.

[0054] In this way, it can be avoided that the CC of the M-TRP always maintains the same TCI as the CC of the S-TRP corresponding to its associated CORESET pool index, thereby preventing the M-TRP from being unable to effectively utilize time-frequency resources for collaborative transmission, so that multiple TRPs of collaborative transmission can flexibly switch transmission and improve transmission performance.

[0055] Optionally, after updating the association between the X carrier lists and the Y CORESET pool indexes, the cells corresponding to the carriers in the X carrier lists will be switched, thereby realizing dynamic switching of the cells. For example, the serving cells corresponding to the carriers in the X carrier lists will be switched.

[0056] Optionally, when the fifth carrier list in the X carrier lists is updated from being associated with the fifth CORESET pool index to being associated with the sixth CORESET pool index, the cell corresponding to the carrier in the fifth carrier list can be switched from the first cell to the second cell, where the first cell is the cell corresponding to the fifth CORESET pool index, and the second cell is the cell corresponding to the sixth CORESET pool index.

[0057] Optionally, the information indication method further includes:

[0058] The terminal receives second indication information, where the second indication information is used to indicate a second association relationship between the TCI states corresponding to the X carrier lists and the Y CORESETpool indexes, where X and Y are integers greater than or equal to 1.

[0059] Thus, the terminal can update the association relationship between the X carrier lists and the TCI states corresponding to the Y CORESETpool indexes according to the second association relationship, thereby implementing TCI update of the CCs in the X carrier lists.

[0060] Optionally, in the second association relationship, when at least one carrier in the sixth carrier list operates in a single-station transmission mode, the sixth carrier list is associated with at most one TCI state, and the sixth carrier list is a carrier list in the X carrier lists. And / or, in the second association relationship, when all carriers in the seventh carrier list operate in a multi-station transmission mode, the seventh carrier list is associated with at least two TCI states, and the seventh carrier list is a carrier list in the X carrier lists.

[0061] Combine the following Figure 2 and Figure 3 This application is described in detail.

[0062] Example 1

[0063] In this embodiment 1, Figure 2As shown, assuming that CC list 1 is associated with CORESET pool index = 0 (i.e., CPI = 0) and CC list 2 is associated with CORESET pool index = 1 (i.e., CPI = 1) through RRC signaling, that is, TRP1 sends a physical downlink control channel (PDCCH) on the service cell corresponding to CORESET pool index = 0, and TRP2 sends PDCCH on the service cell corresponding to CORESET pool index = 1. Then: if the terminal receives the indication information in the MAC CE or DCI as "0", that is, indicating that CC list 1 is associated with CORESET pool index = 1, and CC list-2 is associated with CORESET pool index = 0, then the association relationship between the CC list and the CORESET pool index can be updated based on the indication information to realize dynamic switching transmission of TRP, that is, TRP1 sends PDCCH on the service cell corresponding to CORESET pool index = 1, and TRP2 sends PDCCH on the service cell corresponding to CORESET pool index = 0.

[0064] Example 2

[0065] In this embodiment 2, assuming that CC list 1 = {S-TRP CC1, M-TRP CC3}, CC list 2 = {M-TRP CC2, M-TRP CC3}, '1' indicates association, and '0' indicates non-association, then:

[0066] (a) When the association relationship between CC list and CORESET pool index is shown in Table 2 below, the CORESET pool index = 0 (i.e., CPI = 0) of M-TRP CC3 corresponds to TCI associated with CC list 1, and the CORESET pool index = 1 (i.e., CPI = 1) and 2 of M-TRP CC3 correspond to TCI associated with CC list 2. At this time, if the TCI of the CC of the S-TRP of CC list 1 is updated, the TCI of CORESET pool index = 0 corresponding to M-TRP CC3 in CC list 1 is updated accordingly.

[0067] Table 2

[0068]

[0069] (b) When the association relationship between CC list and CORESET pool index is updated as shown in Table 3 below, the CORESET pool index = 1 of M-TRPCC3 corresponds to TCI associated with CC list 1, and the CORESET pool index = 0 and 2 of M-TRP CC3 correspond to TCI associated with CC list 2. At this time, if the TCI of the CC of the S-TRP of CC list 1 is updated, the TCI of CORESET pool index = 1 corresponding to M-TRP CC3 in CClist1 is updated accordingly.

[0070] Table 3

[0071]

[0072] (c) By updating the association between CC list and CORESET pool index, such as Figure 3 As shown, dynamic switching of the M-TRP CC2 service cell is realized.

[0073] See also Figure 4 , Figure 4 is a flowchart of an information indication method provided by an embodiment of the present application, the method is applied to a network side device, such as Figure 4 As shown, the method comprises the following steps:

[0074] Step 41: The network side device sends first indication information to the terminal, where the first indication information is used to indicate a first association relationship between X carrier lists and Y CORESET pool indexes.

[0075] Here, X and Y are integers greater than or equal to 1. For example, X and Y are both equal to 2; or, X is equal to 2, and Y is equal to 3. One CORESET pool index may correspond to one serving cell, and different CORESET pool indexes may correspond to different TCI states, that is, there is a corresponding relationship between the CORESET pool index and the TCI state.

[0076] In this embodiment, after sending the first indication information to the terminal, the terminal can update the association relationship between the X carrier lists and the Y CORESET pool indexes according to the first association relationship, and then implement TCI update of CCs in the X carrier lists according to the association relationship.

[0077] Optionally, the carrier CC in the X carrier list may operate in a single-station transmission mode, such as an S-TRP scenario, or in a multi-station transmission mode, such as an M-TRP scenario.

[0078] Optionally, after sending the first indication information to the terminal, the network side device may update the association relationship between the X carrier lists and the Y CORESET pool indexes according to the first association relationship.

[0079] Optionally, before sending the first indication information to the terminal, the network side device may send configuration information to the terminal, where the configuration information is used to configure an association relationship between X carrier lists and Y CORESET pool indexes, which is different from the above-mentioned first association relationship. For example, in an S-TRP scenario and / or an M-TRP scenario, the serving cell may first configure an association relationship between X carrier lists and Y CORESET pool indexes through RRC signaling, and then update the association relationship between the X carrier lists and Y CORESET pool indexes through MAC CE or DCI, and this MAC CE or DCII may come from any cell.

[0080] In the embodiment of the present application, in order to indicate the association relationship between X carrier lists and Y CORESET pool indexes, the first indication information may use X*Y bits, or other number of bits. For each bit, it may be '1' for association, '0' for non-association; or '1' for non-association, '0' for association.

[0081] Optionally, the network side device may send the first indication information to the terminal by at least one of the following:

[0082] RRC signaling, MAC CE, DCI.

[0083] For example, if MAC CE is used, a reserved bit or a newly added bit in the unified TCI activation / deactivation field of MAC CE may be used to carry the first indication information to indicate a first association relationship between the X carrier lists and the Y CORESET pool indexes. Alternatively, if DCI is used, a newly added bit in the DCI may be used to carry the first indication information to indicate a first association relationship between the X carrier lists and the Y CORESET pool indexes.

[0084] Optionally, if the X is equal to 2, the Y is equal to 2, and the two carrier lists include carrier list 1 and carrier list 2, and the two CORESET pool indexes include CORESET pool index 0 and CORESET pool index 1, then the first association relationship may include any one of the following:

[0085] 1) Carrier list 1 is associated with CORESET pool index 0, and carrier list 2 is associated with CORESET pool index 1;

[0086] 2) Carrier list 1 is associated with CORESET pool index 1, and carrier list 2 is associated with CORESET pool index 0.

[0087] Optionally, when both X and Y are equal to 2, and the two carrier lists include carrier list 1 and carrier list 2, and the two CORESET pool indexes include CORESET pool index 0 and CORESET pool index 1, if the first indication information uses 1 bit, the indication of the first indication information may include any one of the following:

[0088] (1) When the value of the first indication information is 1, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 0, and the carrier list 2 is associated with the CORESET pool index 1; or, when the value of the first indication information is 0, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 1, and the carrier list 2 is associated with the CORESET pool index 0;

[0089] (2) When the value of the first indication information is 0, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 0, and the carrier list 2 is associated with the CORESET pool index 1; or, when the value of the first indication information is 1, the first indication information indicates that the carrier list 1 is associated with the CORESET pool index 1, and the carrier list 2 is associated with the CORESET pool index 0.

[0090] Optionally, in the first association relationship, when at least one carrier in the first carrier list operates in single-station transmission mode, the first carrier list is associated with at most one CORESET pool index, and the first carrier list is one carrier list in the X carrier lists. For example, for one carrier list in the X carrier lists, if at least one carrier in the one carrier list operates in S-TRP mode, the one carrier list is associated with at most one CORESETpool index.

[0091] Optionally, in the first association relationship, when all carriers in the second carrier list operate in multi-station transmission mode, the second carrier list is associated with at least 2 CORESET pool indexes, and the second carrier list is a carrier list in the X carrier lists. For example, for a carrier list in the X carrier lists, if all carriers in the one carrier list operate in M-TRP mode, the one carrier list is associated with at least 2 CORESET poolindexes to achieve multi-station coordinated transmission.

[0092] Optionally, when the third carrier list in the X carrier lists is associated with the first CORESET pool index, if the TCI state of the first carrier in the third carrier list is updated, the first carrier may be any carrier in the third carrier list, then the TCI states corresponding to the first CORESET pool index of all carriers in the third carrier list are updated consistently; or, if the TCI state corresponding to the second CORESETpool index of the second carrier in the third carrier list is updated, the first carrier may be any carrier in the third carrier list, and the second CORESET pool index is different from the first CORESET pool index, then the TCI states of other carriers in the third carrier list except the second carrier are not updated. In this way, it can be ensured that the carriers in the third carrier list with the same TCI state are updated consistently.

[0093] Optionally, when the fourth carrier list in the X carrier lists is associated with the third CORESET pool index, if the TCI state of the carrier in the single-station transmission mode in the fourth carrier list is updated, the TCI state corresponding to the third CORESET pool index of the carrier in the multi-station transmission mode in the fourth carrier list is consistently updated; or, if the TCI state corresponding to the third CORESET poolindex of the carrier in the multi-station transmission mode in the fourth carrier list is updated, the TCI state of the carrier in the single-station transmission mode in the fourth carrier list is consistently updated; or, if the TCI state corresponding to the fourth CORESET pool index of the carrier in the multi-station transmission mode (such as the M-TRP scenario) in the fourth carrier list is updated, and the fourth CORESET pool index is different from the third CORESET pool index, the TCI state of the carrier in the single-station transmission mode in the fourth carrier list is not updated.

[0094] Optionally, after updating the association between the X carrier lists and the Y CORESET pool indexes, the cells corresponding to the carriers in the X carrier lists will be switched, thereby realizing dynamic switching of the cells. For example, the serving cells corresponding to the carriers in the X carrier lists will be switched.

[0095] Optionally, when the fifth carrier list in the X carrier lists is updated from being associated with the fifth CORESET pool index to being associated with the sixth CORESET pool index, the cell corresponding to the carrier in the fifth carrier list can be switched from the first cell to the second cell, where the first cell is the cell corresponding to the fifth CORESET pool index, and the second cell is the cell corresponding to the sixth CORESET pool index.

[0096] Optionally, the information indication method further includes:

[0097] The network side device sends second indication information to the terminal, where the second indication information is used to indicate a second association relationship between the X carrier lists and the TCI states corresponding to the Y CORESET pool indexes.

[0098] Optionally, in the second association relationship, when at least one carrier in the sixth carrier list operates in a single-station transmission mode, the sixth carrier list is associated with at most one TCI state, and the sixth carrier list is a carrier list in the X carrier lists. And / or, in the second association relationship, when all carriers in the seventh carrier list operate in a multi-station transmission mode, the seventh carrier list is associated with at least two TCI states, and the seventh carrier list is a carrier list in the X carrier lists.

[0099] It should be noted that the information indication method provided in the embodiment of the present application can be executed by an information indication device or a control module in the information indication device for executing the information indication method. In the embodiment of the present application, the information indication device provided in the embodiment of the present application is described by taking the information indication device executing the information indication method as an example.
