The information activation method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.
[0046] As Figure 2 shown, the embodiment of the present application provides an information activation method, comprising the following steps:
[0047] Step 101, the network side device sends a MAC CE command, wherein the MAC CE command comprises at least two first MAC CE commands or a second MAC CE command.
[0048] The first MAC CE command is used to activate a TCI state (i.e., TCI state) corresponding to a first identification information, and the second MAC CE command is used to activate a TCI state corresponding to at least two second identification information; the activated TCI state is used to determine the common beam information of multiple channels.
[0049] The MAC CE command includes two cases. In one case, the MAC CE command comprises at least two first MAC CE commands, and each first MAC CE command is used to activate a TCI state corresponding to a first identification information. This can be understood as a one-to-one correspondence between the first MAC CE command and the first identification information. For example, the network side device can use the first MAC CE command corresponding to each TRP ID (such as the RRC parameter CORESETPoolIndex) to activate the TCI state corresponding to each TRP ID. Further, the network side device uses the DCI on the physical downlink control channel (PDCCH) corresponding to the same TRP ID as the first MAC CE command to indicate the target TCI state corresponding to the TRP ID from the TCI state activated by the first MAC CE command. In another case, the MAC CE command comprises a second MAC CE command, and the second MAC CE command is used to activate a TCI state corresponding to at least two second TRP IDs. This can be understood as a one-to-many correspondence between the second MAC CE command and the second TRP ID.
[0050] In the present application, the at least two first MAC CE commands can be understood as follows: each time a MAC CE command is sent, the MAC CE commands sent at different times can have the same MAC packet data unit (PDU) subheader carrying eLCID, or different MAC PDU subheaders carrying eLCID.
[0051] The activated TCI state comprises at least one of a joint TCI state and a separate TCI state.
[0052] The activated TCI state includes a target TCI state, and the target TCI state is a TCI state used for transmission of multiple channels, which can be understood as common beam information shared by the multiple channels.
[0053] In the embodiments of the present application, a network side device sends a MAC CE command, and the MAC CE command includes at least two first MAC CE commands or a second MAC CE command; the first MAC CE command is used to activate a TCI state corresponding to first identification information, and the second MAC CE command is used to activate TCI states corresponding to at least two second identification information; and the activated TCI state is used to determine common beam information of multiple channels. In the above, in a multi-TRP scenario, the activated TCI state includes TCI states of each TRP used for transmission of multiple channels, so that the same beam on each TRP can be used for transmission of multiple channels in the multi-TRP scenario.
[0054] In the above, the first identification information includes at least one of the following:
[0055] Control resource set (CORESET) identification information;
[0056] CORESET pool identification CORESETPoolIndex;
[0057] TRP identification information;
[0058] Channel group identification information;
[0059] CORESET group identification information;
[0060] Physical uplink control channel (PUCCH) resource group identification information;
[0061] The second identification information includes at least one of the following:
[0062] CORESET identification information;
[0063] CORESETPoolIndex;
[0064] TRP identification information;
[0065] Channel group identification information;
[0066] CORESET group identification information;
[0067] PUCCH resource group identification information.
[0068] The information activation method provided by the embodiments of the present application can be used in a multi-TRP multi-downlink control information (DCI) scenario. For example, a network side device configures two CORESETPoolIndex through RRC signaling, the value of one CORESETPoolIndex is 0, and the value of the other CORESETPoolIndex is 1, and each CORESETPoolIndex can be used as an identifier (ID) of a TRP.
[0069] It should be noted that the multi-TRP scenario can be indirectly identified through configuration of various parameters. For example, multi-DCI (multi-DCI) of the multi-TRP is that the values of the RRC parameters CORESETPoolIndex are configured as 0 and 1, which indirectly identifies two TRPs and is an mDCI scenario.
[0070] The first MAC CE command includes a field for indicating the identifier of the first TRP. For example, the first MAC CE command includes a field for indicating the CORESETPoolIndex.
[0071] In an embodiment of the present application, in the case where the network side device configures a joint TCI mode (joint TCI mode), that is, the joint TCI mode is configured for all TRPs (all first identification information), each TCI state activated according to the first MAC CE command corresponds to a code point, that is, one TCI state in the TCI states activated by the first MAC CE command corresponds to one code point, and the TCI state activated by the first MAC CE command is used for the TRP corresponding to the first identification information indicated in the first MAC CE command, that is, the TCI state activated by the first MAC CE command is used for the first identification information indicated by the first MAC CE command.
[0072] In an embodiment of the present application, in the case where the network side device configures a separate TCI mode (separate TCI mode), that is, the separate TCI mode is configured for all TRPs (all first identification information), each TCI state activated according to the first MAC CE command satisfies one of the following conditions with a code point.
[0073] One code point corresponds to a pair of TCI states, and the pair of TCI states includes one downlink (DL) TCI state and one uplink (UL) TCI state;
[0074] One code point corresponds to one DL TCI state;
[0075] One codepoint corresponds to one UL TCI state.
[0076] In the above, the TCI state activated by the first MAC CE command is used for the TRP corresponding to the first identification information indicated in the first MAC CE command, that is, the TCI state activated by the first MAC CE command is used for the first identification information indicated by the first MAC CE command.
[0077] In an embodiment of the present application, the network side device is allowed to configure joint TCI mode for part of the TRPs (part of the first identification information), and separate TCI mode for another part of the TRPs (another part of the first identification information), and each TCI state activated by the first MAC CE command and the codepoint satisfy one of the following:
[0078] One codepoint corresponds to one joint TCI state;
[0079] One codepoint corresponds to one independent DL TCI state and one independent UL TCI state;
[0080] One codepoint corresponds to one independent DL TCI state;
[0081] One codepoint corresponds to one independent UL TCI state.
[0082] In an embodiment, the network side device does not configure the first identification information as joint TCI mode or independent TCI mode, and the way to distinguish whether the TCI state corresponding to the codepoint is joint or independent can be: according to the TCI state from different TCI state pools to distinguish whether it is joint TCI state, independent DL TCI state or independent UL TCI state, for example, at least two of the joint TCI state, the independent DL TCI state and the independent UL TCI state come from different TCI state pools.
[0083] The way to distinguish whether the TCI state corresponding to the codepoint is joint or independent can also be indicated by adding indication information in the first MAC CE command, for example, the first MAC CE command includes first indication information, and the first indication information is used to indicate that the TCI state corresponding to the codepoint is one of the following:
[0084] The joint TCI state;
[0085] The independent DL TCI state and the independent UL TCI state;
[0086] The independent DL TCI state;
[0087] The independent UL TCI state.
[0088] In an embodiment of the present application, the network-side device activates all TCI states corresponding to the second identification information using a second MAC CE command, and the network-side device uniformly configures all second identification information as a joint TCI mode using RRC signaling. That is, in the case where the network-side device configures the at least two second identification information as a joint TCI mode, the TCI state activated according to the second MAC CE command and the codepoint satisfy one of the following:
[0089] (1) One codepoint corresponds to at least two TCI states, and each TCI state in the at least two TCI states corresponds to different second identification information. Taking the second identification information as TRP identification information as an example, codepoint1 corresponds to TCI state1 and TCI state2, wherein TCI state1 is used as a joint TCI state corresponding to TRP1, and TCI state2 is used as a joint TCI state corresponding to TRP2. The TCI state corresponding to the second identification information includes one joint TCI state.
[0090] (2) Each codepoint corresponds to a TCI state corresponding to one second identification information. For example, the TCI state corresponding to codepoint1 is used as a joint TCI state corresponding to TRP1, and the TCI state corresponding to codepoint2 is used as a joint TCI state corresponding to TRP2. The TCI state corresponding to the second identification information includes one joint TCI state.
[0091] In an embodiment of the present application, the network-side device activates all TCI states corresponding to the second identification information using a second MAC CE command, and the network-side device uniformly configures all second identification information as an independent TCI mode using RRC signaling. That is, in the case where the network-side device configures the at least two second identification information as an independent TCI mode, the TCI state activated according to the second MAC CE command and the codepoint satisfy one of the following:
[0092] (1) One codepoint corresponds to the TCI states corresponding to multiple second identification information in the at least two second identification information, wherein the TCI state corresponding to the second identification information includes at least one of a DL TCI state and a UL TCI state.
[0093] For example, codepoint1 corresponds to TCI state1, TCI state2, TCI state3, TCI state4, wherein TCI state1 and TCI state2 are used as independent DL TCI state and independent UL TCI state corresponding to TRP1, and TCI state3 and TCI state4 are used as independent DL TCI state and independent UL TCI state corresponding to TRP2.
[0094] (2) Each codepoint corresponds to a TCI state corresponding to a second identification information, wherein the TCI state corresponding to the second identification information includes at least one of a DL TCI state and a UL TCI state.
[0095] For example, taking the second identification information as the TRP identification information as an example, the 2 TCI states corresponding to codepoint1 are used as independent DL TCI state and independent UL TCI state corresponding to TRP1, and the 2 TCI states corresponding to codepoint2 are used as independent DL TCI state and independent UL TCI state corresponding to TRP2.
[0096] In an embodiment of the present application, the network side device activates all TCI states corresponding to the second identification information using the second MAC CE command, and configures part of the second identification information as independent TCI mode and another part of the second identification information as joint TCI mode using RRC signaling. That is, the first target identification information includes part of the at least two second identification information, and the second target identification information is the other second identification information in the at least two second identification information except the first target identification information.
[0097] In the case where the network side device configures the first target identification information as joint TCI mode and the second target identification information as independent TCI mode, the TCI state activated according to the second MAC CE command and the codepoint satisfy one of the following:
[0098] (1) One codepoint corresponds to the joint TCI state corresponding to the first target identification information, and the independent TCI state of the second identification information in the second target identification information.
[0099] (2) the first codepoint corresponds to a joint TCI state corresponding to the first target identification information, and the second codepoint corresponds to an independent TCI state corresponding to the second target identification information, the first codepoint is part of the codepoints activated by the second MAC CE command, and the second codepoint is a codepoint other than the first codepoint in the codepoints activated by the second MAC CE command.
[0100] In an embodiment of the present application, the network side device does not configure the second identification information as a joint TCI mode or an independent TCI mode, in which case each TCI state activated according to the second MAC CE command and the codepoint satisfies one of the following:
[0101] (1) the TCI state corresponding to one codepoint includes the TCI state corresponding to each of the at least two second identification information, wherein the TCI state corresponding to the second identification information includes one of the following:
[0102] a joint TCI state;
[0103] an independent DL TCI state and an independent UL TCI state;
[0104] an independent DL TCI state;
[0105] an independent UL TCI state.
[0106] (2) the third codepoint corresponds to the TCI state corresponding to one second identification information, and the fourth codepoint corresponds to the TCI state corresponding to another second identification information, the third codepoint and the fourth codepoint are different codepoints in the codepoints activated by the second MAC CE command, the TCI state corresponding to the one second identification information includes a joint TCI state, and the TCI state corresponding to the another second identification information includes at least one of an independent DL TCI state and an independent UL TCI state.
[0107] In the embodiment, since the network side device does not configure the second identification information as a joint TCI mode or an independent TCI mode, the way to distinguish whether the TCI state corresponding to the codepoint is joint or independent can be: distinguishing from different TCI state pools whether it is a joint TCI state, an independent DL TCI state or an independent UL TCI state, for example, at least two of the joint TCI state, the independent DL TCI state and the independent UL TCI state come from different TCI state pools. Or, by adding indication information in the second MAC CE command to indicate, for example, the second MAC CE command includes second indication information, and the second indication information is used to indicate that the TCI state corresponding to the codepoint is one of the following:
[0108] the joint TCI state;
[0109] the independent DL TCI state and the independent UL TCI state;
[0110] the independent DL TCI state;
[0111] the independent UL TCI state.
[0112] In an embodiment of the present application, the correspondence between the TCI state activated according to the second MAC CE command and the at least two second identification information is determined according to one of the following:
[0113] (1) the third indication information included in the second MAC CE command, the third indication information being used to indicate the correspondence between the code point and the second identification information, or to indicate the correspondence between the TCI state activated by the second MAC CE command and the second identification information;
[0114] (2) the association relationship between the position or order of each TCI state in a plurality of TCI states corresponding to one code point and the identification of each second identification information; here, the position or order of each TCI state refers to that when a plurality of TCI states correspond to one code point, the plurality of TCI states are arranged in a certain order, and the arrangement order or arrangement position of the TCI states has an association relationship with each second identification information.
[0115] (3) the association relationship between the position or order of the code point and the identification of each second identification information; here, the position or order of the code point refers to that when a plurality of TCI code points are activated by the network using the MAC CE, the plurality of code points are arranged in a certain order, and the arrangement order or arrangement position of the code points has an association relationship with each second identification information.
[0116] It should be noted that in the case where the network side device configures the second identification information as the independent TCI mode, the activated TCI state can have a default condition, for example, only the independent DL TCI state is activated, or only the independent UL TCI state is activated. If only the independent DL TCI state is activated, the independent UL TCI state can be defaulted, and the defaulted independent UL TCI state is the same as the last activated independent UL TCI state; if only the independent UL TCI state is activated, the independent DL TCI state can be defaulted, and the defaulted independent DL TCI state is the same as the last activated independent DL TCI state.
[0117] In an embodiment of the present application, the method further comprises: the network-side device sending first configuration information, the first configuration information being used for configuring at least one of the first identification information corresponding to the at least two first MAC CEs as a joint TCI mode or an independent TCI mode, or the first configuration information being used for configuring at least one of the second identification information corresponding to the second MAC CEs as a joint TCI mode or an independent TCI mode.
[0118] That is, the network-side device can configure all the first identification information or all the second identification information as a joint TCI mode or an independent TCI mode at one time, in which case, each of the identification information is either a joint TCI mode or an independent TCI mode, all the first identification information or all the second identification information share one first configuration information, or the network-side device can configure each of the first identification information or the second identification information separately, as a joint TCI mode or an independent TCI mode, in which case, the TCI mode of each of the identification information can be the same or different, and each of the first identification information or the second identification information is configured with one first configuration information.

For example, taking the TRP identification information as the first identification information, DCI transmitted on a CORESET corresponding to TRP ID1 is used to indicate a TCI state activated by a first MAC CE command corresponding to TRP ID1; and DCI transmitted on a CORESET corresponding to TRP ID2 is used to indicate a TCI state activated by a first MAC CE command corresponding to TRP ID2. The fourth target identification information and the fifth target identification information can also be different. The fifth target identification information can include one first identification information or multiple first identification information.
[0129] In another implementation, the target DCI is DCI transmitted on a CORESET corresponding to sixth target identification information, and used to indicate a target TCI state corresponding to each second identification information in the at least two second identification information, wherein the sixth target identification information is a specific identification information or any one identification information in the at least two second identification information. The target DCI can be transmitted by a PDCCH on a CORESET corresponding to the specific identification information or any one identification information, and used to indicate a TCI state activated by a MAC CE corresponding to all identification information IDs.
[0130] In an embodiment of the present application, the first MAC CE command includes a first signaling field, and the first signaling field is used to indicate the target TCI state from TCI states activated by the first MAC CE command;
[0131] Alternatively, the second MAC CE command includes a first signaling field, and the first signaling field is used to indicate the target TCI state from TCI states activated by the second MAC CE command;
[0132] Alternatively, the target DCI includes a first signaling field, and the first signaling field is used to indicate the target TCI state from a TCI state corresponding to a code point indicated by a TCI field of the target DCI.

[0136] Whether the second MAC CE command includes the first signaling field is determined according to at least one of the following:

[0139] Whether the target DCI includes the first signaling field is determined according to at least one of the following:
[0140] (1) Configuration information of the network side device, for example, the network side device can configure the target DCI to include the first signaling field through the configuration information;
[0141] (2) The number of TCI states activated by the first MAC CE command;
[0142] (3) The number of TCI states activated by the second MAC CE command;
[0143] (4) The number of TCI states corresponding to the code point indicated by the TCI field of the target DCI.
[0144] In the above, in the case that the first MAC CE comprises a first signaling field, the first signaling field is used to indicate one of the following:
[0145] one joint TCI state, or one pair of independent TCI states, or one independent UL TCI state, or one independent DL TCI state, in the TCI states activated by the first MAC CE;
[0146] all the TCI states activated by the first MAC CE;
[0147] all the TCI states activated by the first MAC CE, and the order or position of each TCI state;
[0148] or,

[0150] one joint TCI state, or one pair of independent TCI states, or one independent UL TCI state, or one independent DL TCI state, in the TCI states activated by the second MAC CE;
[0151] all the TCI states activated by the second MAC CE;
[0152] all the TCI states activated by the second MAC CE, and the order or position of each TCI state;
[0153] or,
[0154] In the above, in the case that the target DCI comprises a first signaling field, the first signaling field is used to indicate one of the following:
[0155] one joint TCI state, or one pair of independent TCI states, or one independent UL TCI state, or one independent DL TCI state, in the TCI states corresponding to the codepoint indicated by the TCI field of the target DCI;
[0156] all the TCI states corresponding to the codepoint indicated by the TCI field of the target DCI;
[0157] all the TCI states corresponding to the codepoint indicated by the TCI field of the target DCI, and the order or position of each TCI state.
[0158] In an embodiment of the present application, the target DCI is UL DCI, used to indicate a target TCI state from TCI states activated by a first MAC CE command or a second MAC CE command. The first signaling field is a sounding reference signal (SRS) resource set indication field in the UL DCI. The UL DCI is UL DCI scheduling uplink transmission, or UL DCI without uplink scheduling.
[0159] In an embodiment of the present application, in the case that the target TCI state includes multiple joint TCI states, and each of the multiple joint TCI states is associated with or contains uplink power control parameters, it is determined that the TRP mode is a multi-TRP scenario.
[0160] Alternatively, in the case that the target TCI state includes multiple independent UL TCI states, and each of the multiple independent UL TCI states is associated with or contains uplink power control parameters, it is determined that the TRP mode is a multi-TRP scenario.
[0161] Alternatively, in the case that the number of first identification information or second identification information corresponding to the target TCI state indicated by the first signaling field is greater than one, it is determined that the TRP mode is a multi-TRP scenario.
[0162] The uplink power control parameters include path loss reference signal (PLRS), P0, alpha, close loop index, etc. In a multi-TRP scenario, the terminal transmits uplink channels using the target TCI state, and the network side device can schedule a physical uplink shared channel (PUSCH) or PUCCH of multiple TRPs.
[0163] In an embodiment of the present application, in the case that the target TCI state includes multiple joint TCI states, and only one joint TCI state of the multiple joint TCI states is associated with or contains uplink power control parameters, it is determined that the TRP mode is a single-TRP scenario.
[0164] Alternatively, in the case that the target TCI state includes multiple independent UL TCI states, and only one independent UL TCI state of the multiple independent UL TCI states is associated with or contains uplink power control parameters, it is determined that the TRP mode is a single-TRP scenario.
[0165] Alternatively, in the case that the number of first identification information or second identification information corresponding to the target TCI state indicated by the first signaling field is one, it is determined that the TRP mode is a single-TRP scenario.
[0166] In a single-TRP scenario, the terminal transmits an uplink channel using a target TCI state, and the network-side device can only schedule a single-TRP PUSCH or PUCCH.
[0167] As shown in Figure 3 The embodiment of the present application provides an information activation method, which comprises the following steps:
[0168] In step 301, a terminal receives a media access control control element (MAC CE) command, wherein the MAC CE command comprises at least two first MAC CE commands or a second MAC CE command.
[0169] The first MAC CE command is used to activate a transmission configuration indication (TCI) state corresponding to a first identification information; the second MAC CE command is used to activate TCI states corresponding to at least two second identification informations; and the activated TCI states are used to determine common beam information of multiple channels.
[0170] The MAC CE command includes two cases. In one case, the MAC CE command comprises at least two first MAC CE commands, and each first MAC CE command is used to activate a TCI state corresponding to a first identification information. This can be understood as one-to-one correspondence between the first MAC CE command and the first identification information. For example, the network-side device can use the first MAC CE command corresponding to each TRP ID (namely, the RRC parameter CORESETPoolIndex) to activate the TCI state corresponding to each TRP ID. Further, the network-side device uses the DCI on the PDCCH corresponding to the same TRP ID of the first MAC CE command to indicate the target TCI state corresponding to the TRP ID from the TCI state activated by the first MAC CE command. In another case, the MAC CE command comprises a second MAC CE command, and the second MAC CE command is used to activate TCI states corresponding to at least two second TRP IDs. This can be understood as one-to-many correspondence between the second MAC CE command and the second TRP ID.
[0171] In the present application, the at least two first MAC CE commands can be understood as follows: each time a MAC CE command is sent, the MAC CE commands sent at different times can have the same MAC packet data unit (PDU) subheader carrying an eLCID or different MAC PDU subheaders carrying eLCIDs.
[0172] The activated TCI state includes at least one of a joint TCI state and a separate TCI state.
[0173] The activated TCI state includes a target TCI state, and the target TCI state is a TCI state used for transmission of multiple channels, which can be understood as common beam information shared by the multiple channels.
[0174] In the embodiments of the application, a terminal receives a MAC CE command, and the MAC CE command includes at least two first MAC CE commands or a second MAC CE command; the first MAC CE command is used to activate a TCI state corresponding to first identification information, and the second MAC CE command is used to activate a TCI state corresponding to second identification information; and the activated TCI state is used to determine common beam information of multiple channels. In the above, in a multi-TRP scenario, the activated TCI state includes a TCI state of each TRP used for transmission of multiple channels, so that the same beam on each TRP can be used for transmission of multiple channels in the multi-TRP scenario.

[0285] The information activation method performed by the terminal has the same technical features as the information activation method performed by the network side device. For details, refer to the embodiments of the network side device, which will not be described here.
[0286] The information activation method provided by the present application is exemplified below by taking the first identification information or the second identification information including a TRP ID (such as CORESETPoolIndex) as an example.
[0287] Activation mode 1: The network side device uses a MAC CE corresponding to each TRP ID to activate the TCI state corresponding to each TRP ID, that is, the MAC CE has a one-to-one correspondence with the TRP.
[0288] The network side device then uses the DCI on the PDCCH with the same TRP ID corresponding to the MAC CE to activate the TCI state corresponding to the TRP ID.
[0289] (1) The network side device uses one MAC CE to activate the TCI state corresponding to the first TRP ID (such as CORESETPoolIndex with a value of 0), and uses another MAC CE to activate the TCI state corresponding to the second TRP ID (such as CORESETPoolIndex with a value of 1).
[0290] (2) The MAC CE command includes a field representing the TRP ID, such as a field indicating CORESETPoolIndex.
[0291] (3) When the network side device configures the joint TCI mode (jointTCI) or the separate TCI mode (separateTCI) using RRC signaling (for each CORESETPoolIndex):
[0292] (31) For the joint TCI mode, in the TCI state activated by the MAC CE, one TCI state corresponds to one codepoint. The activated TCI state is used for the TRP ID indicated in the MAC CE.
[0293] (32) For the separate TCI mode, in the TCI state activated by the MAC CE, one codepoint can correspond to one DL TCI state and one UL TCI state, or one DL TCI state, or one UL TCI state. The activated TCI state is used for the TRP ID indicated in the MAC CE.
[0294] (4) When the network side device does not explicitly configure joint TCI mode (joint TCI) or separate TCI mode (separate TCI) for each CORESETPoolIndex:
[0295] In the TCI state activated by the MAC CE, one codepoint can correspond to one joint TCI state, or one separate DL TCI state and one separate UL TCI state, or one separate DL TCI state, or one separate UL TCI state.
[0296] Wherein, the way to distinguish whether the codepoint corresponds to joint or separate TCI state is: according to the TCI state from different TCI state pools to distinguish joint, separate DL, separate UL, and / or add indication information in the MAC CE to indicate whether the codepoint corresponds to joint TCI or separate TCI.
[0297] Activation mode 2: The network side device uses the MAC CE corresponding to all TRP IDs (such as CORESETPoolIndex) to activate the TCI state corresponding to all TRP IDs, and the MAC CE has a one-to-many correspondence with the TRP.
[0298] (1) In the case where the network side device configures joint TCI or separate TCI using RRC signaling:
[0299] (11) All TRPs (all CORESETPoolIndex) are uniformly configured as joint TCI, and in the TCI state activated by the MAC CE, the TCI state corresponding to one codepoint corresponds to each TRP, or each codepoint corresponds to a different TRP.
[0300] a) For example: TCI state1 corresponding to codepoint1 is used as the joint TCI state corresponding to TRP1, and TCI state2 corresponding to codepoint1 is used as the joint TCI state corresponding to TRP2;
[0301] b) For example: the TCI state corresponding to codepoint1 is used as the joint TCI state corresponding to TRP1, and the TCI state corresponding to codepoint2 is used as the joint TCI state corresponding to TRP2.
[0302] (12) All TRPs (all CORESETPoolIndex) are configured as separate TCI, and in the TCI state activated by the MAC CE, the TCI state corresponding to one codepoint can include one DL TCI state and one UL TCI state or one DL TCI state or one UL TCI state of each TRP in multiple TRPs, or each codepoint corresponds to a different TRP.
[0303] a) For example: the TCI state1 and TCI state2 corresponding to codepoint1 are used as the separate DL TCI state and separate UL TCI state corresponding to TRP1, and the TCI state3 and TCI state4 corresponding to codepoint1 are used as the separate DL TCI state and separate UL TCI state corresponding to TRP2.
[0304] b) For example: the two TCI states corresponding to codepoint1 are used as the separate DL TCI state and separate UL TCI state corresponding to TRP1, and the two TCI states corresponding to codepoint2 are used as the separate DL TCI state and separate UL TCI state corresponding to TRP2.
[0305] (13) Part of the TRPs (part of the CORESETPoolIndex) are configured as joint TCI, and the other part of the TRPs (the other part of the CORESETPoolIndex) are configured as separate TCI, and in the TCI state activated by the MAC CE, one codepoint can correspond to the joint TCI state of part of the TRPs and the separate TCI state of the other part of the TRPs. Or, some codepoints correspond to the joint TCI state of part of the TRPs, and some codepoints correspond to the separate TCI state of the other part of the TRPs.
[0306] (2) In the case that the network side device does not explicitly configure joint TCI or separate TCI:
[0307] In the TCI state activated by the MAC CE, the TCI state corresponding to one codepoint can include: the TCI state of each TRP (each CORESETPoolIndex) in all TRPs (all CORESETPoolIndex) (which can be joint or separate, but is not mandatory to be both joint and separate at the same time). Or, some codepoints correspond to the joint TCI state of one TRP, and some codepoints correspond to the separate TCI state of one TRP. Among them, the way to distinguish whether the TCI state corresponding to the codepoint is joint or separate is the same as above.
[0308] In the above, the correspondence between the TCI state or codepoint and the TRP (CORESETPoolIndex) can be determined according to the indication information in the MAC CE, or the position or order of each TCI state in the TCI state corresponding to one codepoint is associated with the TRP ID (CORESETPoolIndex), or the position or order of the codepoint is associated with the TRP ID (CORESETPoolIndex).
[0309] Each TCI state activated above can have a default TCI state, at which time the default TCI state indicates that the last activated TCI state is the same.
[0310] In the above, when the network side device configures the joint TCI or separate TCI of each TRP using RRC signaling:
[0311] i. The network side device uniformly configures all TRPs as joint TCI or separate TCI, that is, all TRPs share one configuration information;
[0312] ii. Or, the network side device independently configures each TRP as joint TCI or separate TCI, that is, each TRP has one configuration information. For example, the TRP ID information (CORESETPoolIndex) and the configuration information of the joint TCI and the separate TCI (the mode of the joint TCI and the separate TCI) are associated, or one information contains another information.
[0313] Network-side devices use DCI to indicate the TCI state from the TCI state activated by MAC CE. For multiple TRP scenarios, DCI satisfies:
[0314] 1. For activation mode 1, the DCI transmitted on the CORESET corresponding to TRP ID1 contains a TCI field indicating the TCI state activated by the MAC CE corresponding to TRP ID1. Similarly, the DCI transmitted on the CORESET corresponding to TRP ID2 contains a TCI field indicating the TCI state activated by the MAC CE corresponding to TRP ID2.
[0315] 2. For activation mode 2, DCI can be transmitted via PDCCH on the CORESET corresponding to a specific TRP ID or any TRP ID. This is used to indicate the TCI state activated by the MAC CE corresponding to any TRP ID or all TRP IDs.
[0316] Furthermore, a first signaling field is introduced in the DCI. The first signaling field is used to indicate at least one of the following:
[0317] i. A joint TCI state or a pair of separate TCI states corresponding to the codepoint indicated by the TCI field;
[0318] ii. All TCI states corresponding to the codepoint indicated by the TCI field;
[0319] iii. All TCI states corresponding to the codepoint indicated by the TCI field, and their order or position.
[0320] The existence or omission of the first signaling field is determined based on one of the following:
[0321] Network-side device configuration;
[0322] If MAC CE activates a joint TCI state or a pair of separate TCI states, the network-side device configuration does not have a first signaling domain in DCI;
[0323] If the MAC CE activates a joint TCI state or a pair of separate TCI states, the UE ignores or does not interpret the first signaling domain (even if it exists).
[0324] Further, the first DCI is UL DCI, used to indicate TCI state from the activated TCI state by MAC CE.
[0325] Reuse SRS resource set indicator field in UL DCI, the feature of this field is the same as the description of the first signaling field.
[0326] The first DCI can be UL DCI scheduling uplink transmission, or UL DCI without uplink scheduling.
[0327] Optionally, according to the number of TCI states associated with or containing PC parameters (at least one of PLRS, setting{P0, alpha, close loop index}) in the TCI state indicated by the network side device, the TRP mode is determined:
[0328] (1) If the network side device indicates multiple joint TCI states or separate UL TCI states, and these TCI states are all associated with or contain PC parameters, then:
[0329] i. The number of TRPs corresponding to UL transmission (single TRP or multi-TRP) can be dynamically indicated by the first signaling field in UL DCI, such as indicating a certain TCI state by the first signaling field, which is a single TRP scenario, and indicating multiple TCI states by the first signaling field, which is a multi-TRP scenario
[0330] ii. Or, consider this as a multi-TRP scenario, and the UE transmits uplink channels using the multiple TCI states (the network side device can schedule multi-TRP PUSCH or PUCCH)
[0331] (2) If the network side device indicates multiple joint TCI states or separate UL TCI states, and only one TCI state is associated with or contains PC parameters, then consider this as a single TRP scenario, and the UE transmits uplink channels using the TCI state (the network side device can only schedule single TRP PUSCH or PUCCH).
[0332] The information activation method of the present application can implement a scheme of applying a unified TCI framework in a multi-TRP scenario. The network can activate and indicate a unified TCI state to implement common beams of multiple TRPs in single-DCI and multi-DCI scenarios, and through a beam indication scheme, switching and selection of TRPs in single-TRP and multi-TRP scenarios can be supported, and the unified TCI scheme in the multi-TRP scenario can be supported completely and flexibly.
