Description

[Technical Field]

[0001] The present disclosure relates to the field of communications technology, and more particularly to a method, apparatus, and storage medium for determining a Transmission Configuration Indicator (TCI) status. [Background technology]

[0002] In New Radio (NR) technology, for example, when the communication frequency range is in frequency range 2, high-frequency channels attenuate rapidly, so beam-based transmission and reception are required to ensure coverage.

[0003] In the related art, beams for control channels, data channels, and reference signals are indicated separately. Furthermore, for control channels (Physical Downlink Control Channel (PDCCH) and Physical Uplink Control Channel (PDCCH)) and / or their corresponding Demodulation Reference Signals (DMRS), a Medium Access Control (MAC) Control Element (CE) is used to activate one beam. For data channels (Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH)) and / or their corresponding DMRS, downlink control information (DCI) signaling is used to indicate their respective beams.

[0004] To reduce MAC CE signaling overhead, if a terminal has multiple serving cells, the multiple serving cells can be configured as at least one Component Carrier (CC) list, and one MAC CE can be used to activate or update corresponding TCI states for multiple serving cells belonging to one CC list. However, the serving cell may be configured for transmission based on a single transmission reception point (S-TRP) or a multi-transmission reception point (M-TRP).

[0005] At present, it is not clear how to configure CC lists for a serving cell configured for S-TRP transmission and a serving cell configured for M-TRP transmission. For example, it is an issue to be resolved as to whether a serving cell configured for S-TRP transmission and a serving cell configured for M-TRP transmission can be configured in one CC list.

[0016] Illustrative embodiments will now be described in detail, examples of which are illustrated in the drawings. In the following description, when referring to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with the present disclosure.

[0017] The method for determining a transmission setting indication state according to the embodiment of the present disclosure can be applied to the wireless communication system shown in Fig. 1. As shown in Fig. 1, the wireless communication system includes a network device and a terminal. The terminal connects to the network device through wireless resources and performs data transmission.

[0018] 1 is merely an example, and the wireless communication system may include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices that are not depicted in FIG 1. The embodiments of the present disclosure do not limit the number of network devices and the number of terminals included in the wireless communication system.

[0019] Note that the wireless communication system in the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system may use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance (CSMA). Depending on factors such as different network capacities, speeds, and delays, networks can be divided into 2G (second generation) networks, 3G networks, 4G networks, and future evolutionary networks such as 5G networks, which may also be referred to as new radio networks (NR). For ease of explanation, the present disclosure may also refer to wireless communication networks as networks for short.

[0020] Furthermore, a network device according to the present disclosure may be referred to as a radio access network device. The radio access network device may be a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a radio relay node, a radio backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., a gNB in ​​an NR system, or a component or part of a device constituting a base station. Note that the embodiments of the present disclosure do not limit the specific technology used by the network device or the specific device form. In the present disclosure, a network device can provide communication coverage for a specific geographical area and can communicate with terminals within the coverage (cell). Furthermore, in the case of a vehicle-to-everything (V2X) communication system, the network device may be an in-vehicle device.

[0021] Furthermore, the terminal according to the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the terminal may be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include a mobile phone, customer premises equipment (CPE), pocket personal computer (PPC), personal digital assistant (PDA), laptop, tablet, wearable device, or in-vehicle device. In addition, in the case of a vehicle-to-everything (V2X) communication system, the terminal device may be an in-vehicle device. Note that the embodiments of the present disclosure do not limit the specific technology used by the terminal or the specific device form.

[0022] Related art introduces the use of a unified Transmission Configuration Indicator (unified TCI state) to reduce signaling overhead. The unified TCI state may include a joint TCI state for uplink and downlink to perform joint indication of uplink and downlink. Alternatively, the unified TCI state may include a separate DL TCI state and a separate UL TCI state to indicate Quasi Co-location (QCL) parameters for uplink and downlink, respectively.

[0023] When a network device indicates a separate downlink TCI state, the separate downlink TCI state may be applied to the PDSCH and / or its corresponding DMRS, at least a portion of the PDCCH and / or its corresponding DMRS, and at least a portion of the Channel State Information-Reference Signals (CSI-RS) of the terminal. When a network device indicates a separate uplink TCI state, the separate uplink TCI state may be applied to the PUSCH and / or its corresponding DMRS, the PUCCH and / or its corresponding DMRS, and at least a portion of the Sounding Reference Signals (SRS) of the terminal. When a network device indicates a joint uplink and downlink TCI state, the joint uplink and downlink TCI state may be simultaneously applied to uplink and downlink channels and / or reference signals.

[0024] Here, in the related technology, the unified TCI state can be indicated using radio resource control (RRC) signaling and MAC CE, or the unified TCI state can be indicated using radio resource control (RRC), media access control (MAC) signaling (CE), and downlink control information (DCI). Here, since RRC is used to indicate a TCI state list and TCI is a message dynamically transmitted in DCI, if an activated unified TCI state corresponds to one codepoint in the TCI field of DCI, no additional DCI is required to indicate the TCI state, and in this case, the unified TCI state can be indicated using RRC and MAC CE. In another aspect, if the activated unified TCI state includes unified TCI states corresponding to multiple codepoints in the TCI field of the DCI, it is necessary to indicate one codepoint using the TCI field of the DCI to indicate which unified TCI state corresponding to which codepoint is to be used, and in this case, the unified TCI state can be indicated using the RRC, MAC CE, and DCI.

[0025] Here, the unified TCI state may include a joint TCI state for uplink and downlink, a separate uplink TCI state, and / or a separate downlink TCI state. If the unified TCI state is configured as a joint TCI state for uplink and downlink, the unified TCI state includes the joint TCI state for uplink and downlink; otherwise, the unified TCI state includes at least one of a separate uplink TCI state and a separate downlink TCI state.

[0026] As mentioned above, in order to reduce the signaling overhead of MAC CE, when a terminal has multiple serving cells, the multiple serving cells can be configured as at least one Component Carrier (CC) list, and a single MAC CE can be used to activate or update the corresponding TCI states for multiple serving cells belonging to one CC list. It is currently unclear how to configure the CC lists for a serving cell configured for S-TRP transmission and a serving cell configured for M-TRP transmission. For example, it is currently unclear whether a serving cell configured for S-TRP transmission and a serving cell configured for M-TRP transmission can be configured in one CC list. Furthermore, if a serving cell configured for S-TRP transmission and a serving cell configured for M-TRP transmission are configured in one CC list, how to activate or update the TCI state of each serving cell remains a problem to be solved.

[0027] In view of this, an embodiment of the present disclosure provides a method for determining a transmission configuration indication state, and is directed to a method for activating corresponding TCI states for a serving cell based on S-TRP transmission and a serving cell based on M-TRP transmission configured in one CC list, which can reduce signaling overhead, enable terminals to agree on the recognition of a unified TCI state identifier, and improve the transmission capability based on the unified TCI state.

[0028] Here, for ease of explanation, in the embodiments of the present disclosure, the serving cell based on S-TRP transmission is referred to as the first serving cell, and the serving cell based on M-TRP transmission is referred to as the second serving cell.

[0029] FIG. 2 is a flowchart of a method for determining a transmission setting indication state according to an exemplary embodiment. As shown in FIG. 2, the method is applied to a terminal and includes the following steps S21 to S22.

[0030] In step S21, setting information for determining the CC list is received.

[0031] Here, the CC list corresponds to at least one serving cell, and the at least one serving cell includes a first serving cell based on S-TRP transmission and / or a second serving cell based on M-TRP transmission.

[0032] In step S22, a TCI state activation instruction is received.

[0033] Here, the TCI state activation indication information is used to activate the TCI state of the first serving cell and / or the second serving cell.

[0034] In an embodiment of the present disclosure, a terminal receives configuration information that may include information for determining a CC list and other information, where the CC list includes at least one serving cell, the first serving cell based on S-TRP transmission and / or the second serving cell based on M-TRP transmission.

[0035] In an embodiment of the present disclosure, the TCI state activation instruction information may be one activation instruction information for simultaneously activating one or more serving cells in the CC list, or may be multiple different activation instruction information for respectively activating one or more different serving cells in the CC list.

[0036] Here, in one embodiment, the TCI state activation indication information may be MAC CE signaling.

[0037] By using the technical solution of the embodiment of the present disclosure, the TCI state activation method of the serving cell based on S-TRP transmission and the serving cell based on M-TRP transmission configured in one CC list can be determined, thereby reducing signaling overhead and allowing terminals to agree on the recognition of the unified TCI state identifier, thereby improving the transmission capability based on the unified TCI state.

[0038] In an embodiment of the present disclosure, serving cells corresponding to the same CC list may include one or more first serving cells based on S-TRP transmission and may include one or more second serving cells based on M-TRP transmission.

[0039] Furthermore, the second serving cell based on the M-TRP transmission may include a second serving cell indicated based on a single piece of downlink control information (S-DCI M-TRP) and / or a second serving cell indicated based on multiple pieces of downlink control information (M-DCI M-TRP).

[0040] Here, the S-DCI M-TRP can be determined by the following method: When the PDCCH, PDSCH, PUCCH, PUSCH and their respective corresponding DMRSs are configured for transmission based on multiple TCI states, it can be determined that the corresponding serving cell is based on the S-DCI M-TRP.

[0041] Here, if at least one of the following conditions A, B, and C is satisfied, it may be determined that the PDCCH / PDSCH / PUCCH / PUSCH and their DMRSs are configured for transmission based on multiple TCI states: A: A single frequency network (SFN) transmission method, which transmits using multiple TCI states based on the same time domain resource, frequency domain resource, and DMRS resource; B: Repeat transmission, including a frequency division multiplexing (FDM) method, transmitting based on the same time domain resource, different frequency domain resources, and different TCI states, or including a time division multiplexing (TDM) method, transmitting based on the same frequency domain resource, different time domain resources, and different TCI states; C: Transmission based on multiple DMRS port groups, where the transmission is based on the same time domain resources and frequency domain resources, different DMRS port groups, and different TCI states.

[0042] Here, the M-DCI M-TRP can be determined using the following method: If the CORESETPoolIndex of at least one CORESET among multiple CORESETs of a terminal is set to 1 and the CORESETPoolIndex of at least one other CORESET is set to 0 or is not set to any value, it can be determined that the serving cell corresponding to the terminal is a second serving cell (M-DCI M-TRP) indicated based on multiple downlink control information.

[0043] Note that if the serving cell does not satisfy the S-DCI M-TRP and M-DCI M-TRP judgment conditions, the serving cell is the first serving cell based on S-TRP transmission.

[0044] In an embodiment of the present disclosure, the at least one serving cell corresponding to the same CC list may include at least one first serving cell and at least one second serving cell. Furthermore, the second serving cell may be a second serving cell of the S-DCI M-TRP. In this case, the TCI state activation indication information received by the terminal may be used to activate unified TCI states corresponding to one or more code points, respectively, where the one or more code points include at least one code point corresponding to multiple sets of activated unified TCI states. In this case, the TCI state activation indication information may be indicated based on the TCI state activation indication information of the S-DCI M-TRP serving cell, i.e., the TCI state of the S-DCI M-TRP serving cell may be directly activated based on the received TCI state activation indication information, where one code point may correspond to multiple sets of unified TCI states. Each set of unified TCI states corresponds to one TRP. However, at this time, it is necessary to further specify which set of activated unified TCI states the first serving cell S-TRP will use in this codepoint.

[0045] FIG. 3 is a flowchart of a method for determining the unified TCI state of a first serving cell in an exemplary embodiment. As shown in FIG. 3, the method includes the following step S31.

[0046] In step S31, the unified TCI state of the first serving cell is determined based on the first default rule, or the unified TCI state of the first serving cell is determined based on the first indication information.

[0047] In an embodiment of the present disclosure, if the same CC list includes at least one first serving cell and at least one second serving cell, the second serving cell is an S-DCI M-TRP serving cell, and the TCI state activation indication information received by the terminal activates unified TCI states respectively corresponding to one or more code points, and the one or more code points include at least one code point corresponding to multiple sets of activated unified TCI states, then the unified TCI state of the first serving cell may be determined based on a first default rule or first indication information.

[0048] FIG. 4 is a flowchart of a method for determining the unified TCI state of the first serving cell based on a first default rule, shown in an exemplary embodiment. As shown in FIG. 4, the method includes the following step S41:

[0049] In step S41, a designated unified TCI state corresponding to a first code point corresponding to the multiple sets of unified TCI states is determined as the unified TCI state corresponding to the first code point of the first serving cell, and / or a unified TCI state corresponding to a second code point corresponding to a set of unified TCI states is determined as the unified TCI state corresponding to the second code point of the first serving cell.

[0050] In one example, if the first codepoint, codepoint#0, activated by the TCI state activation indication information corresponds to two unified TCI states, unified TCI state#1 and unified TCI state#2, and unified TCI state#1 is located in the bit position of the first unified TCI state corresponding to codepoint#0, and unified TCI state#2 is located in the bit position of the second unified TCI state corresponding to codepoint#0, the first default rule may be to use unified TCI state#1, which is the first unified TCI state corresponding to codepoint#0, or unified TCI state#2, which is the second unified TCI state corresponding to codepoint#0, as the unified TCI state corresponding to the first codepoint of the first serving cell.

[0051] In another example, if the second codepoint codepoint#1 activated by the TCI state activation indication information corresponds to one unified TCI state, i.e., unified TCI state#3, then the unified TCI state#3 is directly used as the unified TCI state corresponding to the second codepoint of the first serving cell.

[0052] FIG. 5 is a flowchart of a method for determining the unified TCI state of the first serving cell according to the first indication information in an exemplary embodiment. As shown in FIG. 5, the method includes the following step 51:

[0053] In step S51, the first instruction information indicates that the Xth unified TCI state corresponding to the code point activated by the TCI state activation instruction information is the unified TCI state of the first serving cell, or the first instruction information indicates that the Yth unified TCI state corresponding to each code point activated by the TCI state activation instruction information is the unified TCI state of the first serving cell.

[0054] where X and Y are positive integers, and the value of Y may be the same or different for different code points.

[0055] In one example, the first instruction information may instruct all codepoints activated by the TCI state activation instruction information to use the Xth unified TCI state of the codepoint as the unified TCI state corresponding to the corresponding codepoint of the first serving cell.The first codepoint, codepoint#0, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#01 and unified TCI state#02, where unified TCI state#01 is located in the bit position of the first unified TCI state corresponding to codepoint#0, and unified TCI state#02 is located in the bit position of the second unified TCI state corresponding to codepoint#0. The first codepoint, codepoint#1, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#11 and unified TCI state#12, where unified TCI state#11 is located in the bit position of the first unified TCI state corresponding to codepoint#1, and unified TCI state#12 is located in the bit position of the second unified TCI state corresponding to codepoint#1. The first codepoint, codepoint#2, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#21 and unified TCI state#22. state, where unified TCI state #21 is located in the bit position of the first unified TCI state corresponding to codepoint #2, unified TCI state #22 is located in the bit position of the second unified TCI state corresponding to codepoint #2, etc., the first indication information can indicate that all codepoints activated by the TCI state activation indication information use the Xth unified TCI state of the codepoint as the unified TCI state corresponding to the corresponding codepoint of the first serving cell.For example, if X=1, then codepoint #0, codepoint #1, codepoint #2, etc. of the first serving cell correspond to the first unified TCI state of the codepoint, i.e., codepoint #0 corresponds to unified TCI state #01, codepoint #1 corresponds to unified TCI state #11, codepoint #2 corresponds to unified TCI state #21, etc. Alternatively, if X=2, then codepoint #0, codepoint #1, codepoint #2, etc. of the first serving cell correspond to the second unified TCI state of the codepoint, i.e., codepoint #0 corresponds to unified TCI state #02, codepoint #1 corresponds to unified TCI state #12, codepoint #2 corresponds to unified TCI state #22, etc.

[0056] In another example, the first instruction information may instruct each codepoint activated by the TCI state activation instruction information to use the Yth unified TCI state in each codepoint as the unified TCI state corresponding to the corresponding codepoint in the first serving cell, where X and Y are positive integers, and the value of Y may be the same or different for different codepoints.The first codepoint, codepoint#0, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#01 and unified TCI state#02, where unified TCI state#01 is located in the bit position of the first unified TCI state corresponding to codepoint#0, and unified TCI state#02 is located in the bit position of the second unified TCI state corresponding to codepoint#0. The first codepoint, codepoint#1, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#11 and unified TCI state#12, where unified TCI state#11 is located in the bit position of the first unified TCI state corresponding to codepoint#1, and unified TCI state#12 is located in the bit position of the second unified TCI state corresponding to codepoint#1. The first codepoint, codepoint#2, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#21 and unified TCI state#22. If the first instruction information corresponds to a unified TCI state, where unified TCI state #21 is located in the bit position of the first unified TCI state corresponding to codepoint #2, unified TCI state #22 is located in the bit position of the second unified TCI state corresponding to codepoint #2, etc., the first instruction information can instruct all codepoints activated by the TCI state activation instruction information to use the Yth unified TCI state in each codepoint as the unified TCI state corresponding to the corresponding codepoint of the first serving cell.For example, if Y=1 for codepoint codepoint#0, and Y=2 for codepoint#1 and codepoint#2, etc., then codepoint#0 of the first serving cell corresponds to the first unified TCI state of that codepoint, i.e., codepoint#0 corresponds to unified TCI state#01, and codepoint#1, codepoint#2, etc. of the first serving cell all correspond to the second unified TCI state of that codepoint, i.e., codepoint#1 corresponds to unified TCI state#12, codepoint#2 corresponds to unified TCI state#22, etc. Alternatively, if Y=2 for codepoint codepoint#1 and Y=1 for codepoint codepoint#0 and codepoint codepoint#2, then codepoint#1 of the first serving cell corresponds to the second unified TCI state of the codepoint, i.e., codepoint#1 corresponds to unified TCI state#12, and codepoint#0 and codepoint#2 of the first serving cell correspond to the first unified TCI state of the codepoint, i.e., codepoint#0 corresponds to unified TCI state#01, and codepoint#2 corresponds to unified TCI state#21.

[0057] In an embodiment of the present disclosure, the at least one serving cell corresponding to the same CC list may include at least one first serving cell and at least one second serving cell. Furthermore, the second serving cell may be a second serving cell (M-DCI M-TRP) indicated based on multiple pieces of downlink control information. In this case, the TCI state activation indication information received by the terminal may be used to activate unified TCI states corresponding to one or more CORESETPoolIndexes. In this case, the TCI state activation indication information may be similarly indicated based on the TCI state activation indication information of the M-DCI M-TRP serving cell. That is, the TCI state of the M-DCI M-TRP serving cell may be directly activated based on the received TCI state activation indication information. Here, one CORESETPoolIndex may activate unified TCI states corresponding to one or more codepoints, and each codepoint corresponds to one set of unified TCI states. For example, one CORESETPoolIndex may be understood to correspond to one TRP. However, in this case, it is necessary to further specify which activated TCI state corresponding to which CORESETPoolIndex the first serving cell S-TRP uses. Note that different CORESETPoolIndexes can be activated by the same TCI state activation indication information, or by different TCI state activation indication information. Furthermore, the TCI state activation indication information may include one or more CORESETPoolIndexes.

[0058] FIG. 6 is a flowchart of a method for determining the unified TCI state of a first serving cell according to an exemplary embodiment. As shown in FIG. 6, the method includes the following step S61.

[0059] In step S61, the unified TCI state of the first serving cell is determined based on the second default rule, or the unified TCI state of the first serving cell is determined according to the second indication information.

[0060] In an embodiment of the present disclosure, if the same CC list includes at least one first serving cell and at least one second serving cell, the second serving cell is an M-DCI M-TRP serving cell, and the TCI state activation indication information received by the terminal activates unified TCI states corresponding to one or more codepoints corresponding to each CORESETPoolIndex, respectively, and for each CORESETPoolIndex, each codepoint among the one or more codepoints corresponds to a set of activated unified TCI states, the unified TCI state of the first serving cell can be determined based on a second default rule or second indication information.

[0061] FIG. 7 is a flowchart of a method for determining the unified TCI state of the first serving cell based on a second default rule in an exemplary embodiment. As shown in FIG. 7, the method includes the following step S71:

[0062] In step S71, it is determined that the unified TCI state corresponding to the Q-th CORESETPoolIndex among the plurality of CORESETPoolIndex is the unified TCI state of the first serving cell. where Q is a positive integer.

[0063] In one example, when the TCI state activation instruction information activates unified TCI states corresponding to two CORESETPoolIndexes, for example, when the first TCI state activation instruction information activates the unified TCI state corresponding to CORESETPoolIndex#0 and the second TCI state activation instruction information activates the unified TCI state corresponding to CORESETPoolIndex#1, the second default rule may be to use the unified TCI state corresponding to CORESETPoolIndex#0 as the unified TCI state corresponding to the first serving cell, or to use the unified TCI state corresponding to CORESETPoolIndex#1 as the unified TCI state corresponding to the first serving cell.

[0064] FIG. 8 is a flowchart of a method for determining the unified TCI state of the first serving cell according to the second indication information, as shown in FIG. 8, the method may include the following steps:

[0065] In step S81, it is determined that the unified TCI state corresponding to the P-th CORESETPoolIndex among the plurality of CORESETPoolIndexes is the unified TCI state of the first serving cell based on the second indication information. where P is a positive integer.

[0066] In one example, the second indication information can indicate that the unified TCI state corresponding to CORESETPoolIndex#0 or CORESETPoolIndex#1 activated by the TCI state activation indication information is the unified TCI state of the first serving cell, where P is a positive integer.

[0067] Using the technical solution of the embodiments of the present disclosure, if the at least one serving cell corresponding to the same CC list may include at least one first serving cell and at least one second serving cell, and the at least one second serving cell is an S-DCI M-TRP serving cell, and the TCI state activation indication activates unified TCI states respectively corresponding to one or more code points, where the one or more code points include at least one code point corresponding to multiple sets of activated unified TCI states, or if the at least one second serving cell is an M-DCI M-TRP serving cell and the TCI state activation indication activates unified TCI states respectively corresponding to one or more CORESETPoolIndexes, then a manner for determining the unified TCI state of the first serving cell is determined, thereby reducing signaling overhead and enabling terminals to agree on recognizing unified TCI state identifiers, and improving transmission capability based on the unified TCI state.

[0068] In the embodiments of the present disclosure, the first indication information and / or the second indication information may be included in a radio resource control signaling (RRC) and / or a media access control (MAC) CE. Furthermore, the TCI state activation indication information and the first indication information may be included in the same media access control (MAC) CE or different MAC CEs, and / or the TCI state activation indication information and the second indication information may be included in the same media access control (MAC) CE or different MAC CEs.

[0069] In an embodiment of the present disclosure, a set of unified TCI states in the unified TCI state includes a joint transmission configuration indication state, or a set of unified TCI states includes at least one of an uplink transmission configuration indication state and a downlink transmission configuration indication state.

[0070] FIG. 9 is a flowchart of a method for determining a transmission setting indication state shown in an exemplary embodiment. As shown in FIG. 9, the method is applied to a network device and includes the following steps S91 to S92.

[0071] In step S91, setting information for determining the CC list is transmitted.

[0072] Here, the CC list corresponds to at least one serving cell, and the at least one serving cell includes a first serving cell based on S-TRP transmission and / or a second serving cell based on M-TRP transmission.

[0073] In step S92, the TCI state activation instruction information is transmitted.

[0074] Here, the TCI state activation indication information is used to activate the TCI state of the first serving cell and / or the second serving cell.

[0075] In an embodiment of the present disclosure, the TCI state activation instruction information may be one activation instruction information for simultaneously activating one or more serving cells in the CC list, or may be multiple different activation instruction information for respectively activating one or more different serving cells in the CC list.

[0076] Here, in one embodiment, the TCI state activation indication information may be carried in MAC CE signaling.

[0077] In an embodiment of the present disclosure, among at least one serving cell corresponding to the same CC list, multiple serving cells are first serving cells, or among at least one serving cell corresponding to the same CC list, multiple serving cells are second serving cells.

[0078] In an embodiment of the present disclosure, the second serving cell includes a second serving cell indicated based on S-DCI (S-DCI M-TRP) and / or a second serving cell indicated based on M-DCI (M-DCI M-TRP).

[0079] Here, the S-DCI M-TRP can be determined by the following method: When the PDCCH, PDSCH, PUCCH, PUSCH and their respective corresponding DMRSs are configured for transmission based on multiple TCI states, it can be determined that the corresponding serving cell is based on the S-DCI M-TRP.

[0080] Here, if at least one of the following conditions A, B, and C is satisfied, it may be determined that the PDCCH / PDSCH / PUCCH / PUSCH and their DMRSs are configured for transmission based on multiple TCI states: A: A single frequency network (SFN) transmission method, which transmits using multiple TCI states based on the same time domain resource, frequency domain resource, and DMRS resource; B: Repeat transmission, including a frequency division multiplexing (FDM) method, transmitting based on the same time domain resource, different frequency domain resources, and different TCI states, or including a time division multiplexing (TDM) method, transmitting based on the same frequency domain resource, different time domain resources, and different TCI states; C: Transmission based on multiple DMRS port groups, where the transmission is based on the same time domain resources and frequency domain resources, different DMRS port groups, and different TCI states.

[0081] Here, the M-DCI M-TRP can be determined using the following method: If the CORESETPoolIndex of at least one CORESET among multiple CORESETs of the terminal is set to 1 and the CORESETPoolIndex of at least one other CORESET is set to 0 or is not set to any value, it can be determined that the serving cell corresponding to the terminal is a second serving cell M-DCI M-TRP indicated based on multiple downlink control information.

[0082] Note that if the serving cell does not satisfy the S-DCI M-TRP and M-DCI M-TRP judgment conditions, the serving cell is the first serving cell based on S-TRP transmission.

[0083] In the embodiment of the present disclosure, the at least one serving cell corresponding to the same CC list includes at least one first serving cell and at least one second serving cell.

[0084] In an embodiment of the present disclosure, the second serving cell is a second serving cell indicated based on the single downlink control information.

[0085] In an embodiment of the present disclosure, the at least one serving cell corresponding to the same CC list may include at least one first serving cell and at least one second serving cell. Furthermore, the second serving cell may be a second serving cell of the S-DCI M-TRP. In this case, the TCI state activation indication information received by the terminal may be used to activate unified TCI states corresponding to one or more code points, respectively, where the one or more code points include at least one code point corresponding to multiple sets of activated unified TCI states. In this case, the TCI state activation indication information may be indicated based on the TCI state activation indication information of the S-DCI M-TRP serving cell, i.e., the TCI state of the S-DCI M-TRP serving cell may be directly activated based on the received TCI state activation indication information, where one code point may correspond to multiple sets of unified TCI states. Each set of unified TCI states corresponds to one TRP. However, at this time, it is necessary to further restrict which set of activated unified TCI states the first serving cell S-TRP uses in that codepoint.

[0086] In an embodiment of the present disclosure, the TCI state activation instruction information activates unified TCI states corresponding to one or more code points, respectively, and the one or more code points include at least one code point corresponding to multiple sets of activated unified TCI states. The unified TCI state of the first serving cell is determined in the following manner: the unified TCI state of the first serving cell is determined based on a first default rule, or the unified TCI state of the first serving cell is determined according to the first instruction information.

[0087] In an embodiment of the present disclosure, determining a unified TCI state of a first serving cell based on a first default rule includes determining a specified unified TCI state corresponding to a first code point corresponding to multiple sets of unified TCI states as the unified TCI state corresponding to the first code point of the first serving cell, and / or determining a unified TCI state corresponding to a second code point corresponding to a set of unified TCI states as the unified TCI state corresponding to the second code point of the first serving cell.

[0088] In one example, if the first codepoint codepoint#0 activated by the TCI state activation indication information corresponds to two unified TCI states, unified TCI state#1 and unified TCI state#2, and unified TCI state#1 is located in the bit position of the first unified TCI state corresponding to codepoint#0, and unified TCI state#2 is located in the bit position of the second unified TCI state corresponding to codepoint#0, the first default rule may be to use unified TCI state#1, which is the first unified TCI state corresponding to codepoint#0, or unified TCI state#2, which is the second unified TCI state corresponding to codepoint#0, as the unified TCI state corresponding to the first codepoint of the first serving cell.

[0089] In another example, if the second codepoint codepoint#1 activated by the TCI state activation indication information corresponds to one unified TCI state, unified TCI state#3, the unified TCI state#3 is directly used as the unified TCI state corresponding to the second codepoint of the first serving cell.

[0090] In an embodiment of the present disclosure, determining the unified TCI state of the first serving cell using the first indication information includes: using the first indication information to indicate that the Xth unified TCI state corresponding to the code point activated by the TCI state activation indication information is the unified TCI state of the first serving cell (X is a positive integer); or using the first indication information to indicate that the Yth unified TCI states corresponding to each code point activated by the TCI state activation indication information are the unified TCI states of the first serving cell (Y is a positive integer), and for different code points, the possible values ​​of Y may be the same or different.

[0091] In one example, the first instruction information can instruct all codepoints activated by the TCI state activation instruction information to use the Xth unified TCI state of the codepoint as the unified TCI state corresponding to the corresponding codepoint of the first serving cell.In one example, the first codepoint, codepoint#0, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#01 and unified TCI state#02, where unified TCI state#01 is located in the bit position of the first unified TCI state corresponding to codepoint#0, and unified TCI state#02 is located in the bit position of the second unified TCI state corresponding to codepoint#0; the first codepoint, codepoint#1, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#11 and unified TCI state#12, where unified TCI state#11 is located in the bit position of the first unified TCI state corresponding to codepoint#1, and unified TCI state#12 is located in the bit position of the second unified TCI state corresponding to codepoint#1; the first codepoint, codepoint#2, activated by the TCI state activation instruction corresponds to unified TCI state#21 and unified TCI state#22. If the first indication information corresponds to two unified TCI states, unified TCI state #21 and unified TCI state #22, where unified TCI state #21 is located in the bit position of the first unified TCI state corresponding to codepoint #2 and unified TCI state #22 is located in the bit position of the second unified TCI state corresponding to codepoint #2, etc., the first indication information can indicate that all codepoints activated by the TCI state activation indication information use the Xth unified TCI state of the codepoint as the unified TCI state corresponding to the corresponding codepoint of the first serving cell.For example, if X=1, then codepoint #0, codepoint #1, codepoint #2, etc. of the first serving cell correspond to the first unified TCI state of the codepoint, i.e., codepoint #0 corresponds to unified TCI state #01, codepoint #1 corresponds to unified TCI state #11, codepoint #2 corresponds to unified TCI state #21, etc. Alternatively, if X=2, then codepoint #0, codepoint #1, codepoint #2, etc. of the first serving cell correspond to the second unified TCI state of the codepoint, i.e., codepoint #0 corresponds to unified TCI state #02, codepoint #1 corresponds to unified TCI state #12, codepoint #2 corresponds to unified TCI state #22, etc.

[0092] In another example, the first instruction information may instruct each codepoint activated by the TCI state activation instruction information to use the Yth unified TCI state in each codepoint as the unified TCI state corresponding to the corresponding codepoint in the first serving cell, where X and Y are positive integers, and the value of Y may be the same or different for different codepoints.The first codepoint, codepoint#0, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#01 and unified TCI state#02, where unified TCI state#01 is located in the bit position of the first unified TCI state corresponding to codepoint#0, and unified TCI state#02 is located in the bit position of the second unified TCI state corresponding to codepoint#0. The first codepoint, codepoint#1, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#11 and unified TCI state#12, where unified TCI state#11 is located in the bit position of the first unified TCI state corresponding to codepoint#1, and unified TCI state#12 is located in the bit position of the second unified TCI state corresponding to codepoint#1. The first codepoint, codepoint#2, activated by the TCI state activation instruction corresponds to two unified TCI states, unified TCI state#21 and unified TCI state#22. If the first instruction information corresponds to a unified TCI state, where unified TCI state #21 is located in the bit position of the first unified TCI state corresponding to codepoint #2, unified TCI state #22 is located in the bit position of the second unified TCI state corresponding to codepoint #2, etc., the first instruction information can instruct all codepoints activated by the TCI state activation instruction information to use the Yth unified TCI state in each codepoint as the unified TCI state corresponding to the corresponding codepoint of the first serving cell.For example, if Y=1 for codepoint codepoint#0, and Y=2 for codepoint#1 and codepoint#2, etc., then codepoint#0 of the first serving cell corresponds to the first unified TCI state of that codepoint, i.e., codepoint#0 corresponds to unified TCI state#01, and codepoint#1, codepoint#2, etc. of the first serving cell all correspond to the second unified TCI state of that codepoint, i.e., codepoint#1 corresponds to unified TCI state#12, codepoint#2 corresponds to unified TCI state#22, etc. Alternatively, if Y=2 for codepoint codepoint#1 and Y=1 for codepoint codepoint#0 and codepoint codepoint#2, then codepoint#1 of the first serving cell corresponds to the second unified TCI state of the codepoint, i.e., codepoint#1 corresponds to unified TCI state#12, and codepoint#0 and codepoint#2 of the first serving cell correspond to the first unified TCI state of the codepoint, i.e., codepoint#0 corresponds to unified TCI state#01, and codepoint#2 corresponds to unified TCI state#21.

[0093] In an embodiment of the present disclosure, the second serving cell may be a second serving cell indicated based on multiple pieces of downlink control information. In this case, the TCI state activation indication information received by the terminal may be used to activate unified TCI states corresponding to one or more CORESETPoolIndexes. In this case, the TCI state activation indication information may similarly be indicated based on the TCI state activation indication information of the M-DCI M-TRP serving cell. That is, the TCI state of the M-DCI M-TRP serving cell may be directly activated based on the received TCI state activation indication information. Here, one CORESETPoolIndex may correspondingly activate unified TCI states corresponding to one or more codepoints, and each codepoint corresponds to one set of unified TCI states. For example, one CORESETPoolIndex may be understood to correspond to one TRP. However, in this case, the activated TCI state corresponding to which CORESETPoolIndex the first serving cell S-TRP uses needs to be further specified. It should be noted that different CORESETPoolIndexes can be activated by the same TCI state activation instruction information, or by different TCI state activation instruction information. Furthermore, the TCI state activation instruction information may include one or more CORESETPoolIndexes.

[0094] In an embodiment of the present disclosure, the TCI state activation instruction information activates a unified TCI state corresponding to one or more CORESETPoolIndexes, respectively, and the unified TCI state of the first serving cell is determined in the following manner: the unified TCI state of the first serving cell is determined based on the second default rule, or the unified TCI state of the first serving cell is determined according to the second instruction information.

[0095] In an embodiment of the present disclosure, determining the unified TCI state of the first serving cell based on the second default rule includes determining that the unified TCI state corresponding to the Qth CORESETPoolIndex among the multiple CORESETPoolIndexes is the unified TCI state of the first serving cell (Q is a positive integer).

[0096] In one example, when the TCI state activation instruction information activates unified TCI states corresponding to two CORESETPoolIndexes, for example, when the first TCI state activation instruction information activates the unified TCI state corresponding to CORESETPoolIndex#0 and the second TCI state activation instruction information activates the unified TCI state corresponding to CORESETPoolIndex#1, the second default rule may be to use the unified TCI state corresponding to CORESETPoolIndex#0 as the unified TCI state corresponding to the first serving cell, or to use the unified TCI state corresponding to CORESETPoolIndex#1 as the unified TCI state corresponding to the first serving cell.

[0097] In an embodiment of the present disclosure, determining the unified TCI state of the first serving cell using the second instruction information includes indicating, using the second instruction information, that the unified TCI state corresponding to the P-th CORESETPoolIndex among the multiple CORESETPoolIndexes is the unified TCI state of the first serving cell (P is a positive integer).

[0098] In one example, the second indication information can indicate that CORESETPoolIndex#0 or CORESETPoolIndex#1 activated by the TCI state activation indication information is the unified TCI state of the first serving cell, where P is a positive integer.

[0099] In an embodiment of the present disclosure, the first indication information and / or the second indication information are included in radio resource control signaling and / or media access control control element signaling.

[0100] In an embodiment of the present disclosure, the TCI state activation instruction information and the first instruction information are included in the same media access control control element signaling, and / or the TCI state activation instruction information and the second instruction information are included in the same media access control control element signaling.

[0101] In an embodiment of the present disclosure, a set of unified TCI states in the unified TCI state includes a joint transmission configuration indication state, or a set of unified TCI states in the unified TCI state includes at least one of an uplink transmission configuration indication state and a downlink transmission configuration indication state.

[0102] By using the technical solution of the embodiment of the present disclosure, the TCI state activation method of the serving cell based on S-TRP transmission and the serving cell based on M-TRP transmission configured in one CC list can be determined, thereby reducing signaling overhead and allowing terminals to agree on the recognition of the unified TCI state identifier, thereby improving the transmission capability based on the unified TCI state.
