Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to a method, device, and storage medium for determining a transmission configuration indication (TCI) status. Background Art

[0002] In New Radio (NR) technology, for example, when the communication band is in frequency range 2, beam-based transmission and reception are required to ensure coverage due to the rapid attenuation of high-frequency channels. When a network device (such as a base station) has multiple Transmission Reception Points (TRPs), multiple TRPs can be used to provide services to terminals, including using multiple TRPs to send physical downlink control channels (PDCCHs) to terminals.

[0003] In the related art, the use of multiple TRPs for repeated transmission of PDCCH (Multi-TRP PDCCHrepetition) is supported. For example, in Multi-TRP PDCCH repetition, two control resource sets (ControlResource Set, CORESET) are configured, and the TCI state (state) corresponding to the CORESET is configured. Each CORESET is configured with a corresponding TCI state, and the search space set (Search Space set, SS set) is configured to be associated with the two CORESETs respectively. That is, two SS sets with a link relationship are configured, and different CORESETs are associated with different TCI states. Among them, the two SS sets with a link relationship can be understood as two PDCCH candidates with the same PDCCH candidate resource (candidate) index (index) in the two SS sets used to send a downlink control information (Downlink ControlInformation, DCI). In the traditional method, the TCI state of PDSCHrepetition is indicated based on a single downlink control signaling (single-DCI, S-DCI), that is, the control resource set pool index (CORESETPoolIndex) of the CORESET corresponding to the DCI is the same.

[0004] However, when the CORESETPoolIndex of the CORESETs corresponding to multiple linked SS sets used for PDCCH repetition transmission is different, how to configure the TCI state corresponding to the codepoint of the TCI field in the DCI carried by the PDCCHcandidate in the multiple linked SS sets is a problem that needs to be solved. Summary of the Invention

[0098] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0099] The TCI status determination method provided in the embodiment of the present disclosure can be applied to Figure 1 In the wireless communication system shown in FIG. Figure 1 As shown in FIG, the wireless communication system includes a terminal and a network device. The terminal is connected to the network device via wireless resources and performs data transmission and reception.

[0100] It is understandable that Figure 1 The wireless communication system shown is only for schematic illustration. The wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices. Figure 1 The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0101] It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt 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), carrier sense multiple access / collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, which can also be called New Radio (NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as simply a network.

[0102] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices. The wireless access network devices may be: base stations, evolved node B (eNB), home base stations, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless backhaul nodes, transmission points (TPs) or transmission and reception points (TRPs), etc., and may also be gNBs in NR systems, or may also be components or part of devices constituting base stations. In the case of a vehicle-to-everything (V2X) communication system, the network device may also be an on-board device. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited.

[0103] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0104] In the present disclosure, data transmission between a network device and a terminal is based on a beam. During the process of data transmission based on a beam, a network device (such as a base station) can use multiple TRPs (multiple TRPs are also called Multi-TRPs) to send PDCCH to the terminal. In the related art, when a network device (such as a base station) uses one TRP to send PDCCH to a terminal, the terminal is configured with a TCI state for receiving the PDCCH. For example, the configuration method is: configure a CORESET such as CORESET#1 for the terminal, and configure the terminal to use TCI#1 when receiving the PDCCH in the CORESET#1 resource. And configure a search space set (Search Space set, SS set) for the terminal, which is associated with CORESET#1. When the terminal receives the PDCCH on the resource in the SS set, it uses the beam corresponding to TCI#1 to receive it. Currently, each SS set can only be associated with one CORESET, and each CORESET is configured with only one TCI state (TCI state is also called TCI state).

[0105] In the present disclosure, data transmission between a network device and a terminal is performed based on beams. During beam-based data transmission, when a network device (e.g., a base station) uses multiple Transmission Relay Protocols (TRPs) (also referred to as Multi-TRPs) to transmit a PDCCH to a terminal, different TRPs use different beams for transmission. Multiple TRPs can transmit the same PDCCH.

[0106] To enable multiple TRPs to send the same PDCCH, there is currently a method: configure two CORESETs, each corresponding to a TCI state, and configure SS sets to be associated with the two CORESETs respectively. That is, two SS sets are configured, associated with different CORESETs and corresponding to different TCI states. Among them, the PDCCHcandidates of the two associated SS sets are also associated. For example, if SS set #1 and SS set #2 are associated, then PDCCHcandidate #i in SS set #1 is associated with PDCCH candidate #i in SS set #2, that is, two PDCCH candidates with the same index are used to send the same DCI.

[0107] One application scenario in which multiple TRPs send the same PDCCH is Multi-TRP PDCCH repetition. In Multi-TRP PDCCH repetition, two CORESETs are configured, and the corresponding TCI states are configured. Each CORESET is configured with a corresponding TCI state, and two linked SS sets are configured, associating different CORESETs with different corresponding TCI states. The two linked SS sets can be understood as two PDCCH candidates with the same PDCCH candidate index in the two SS sets used to send a DCI.

[0108] In the traditional method, the S-DCI mechanism is supported to indicate the TCI status, that is, the CORESETPoolIndex of all DCI corresponding CORESETs is the same. In the related art, the multi-DCI (M-DCI) mechanism is also supported to indicate the TCI status, that is, the CORESETPoolIndex of the CORESETs corresponding to different DCIs may be different.

[0109] The following first describes the S-DCI mechanism and the M-DCI mechanism.

[0110] In the S-DCI mechanism, all CORESETs correspond to a CORESETPoolIndex of 0 or no CORESETPoolIndex value is configured. Each codepoint in the TCI field in DCI signaling can correspond to up to two TCI states. The correspondence is determined by the Medium Access Control (MAC) control element (CE) and does not need to distinguish between different TRPs. Figure 2 Figure 1 shows a schematic diagram of the MAC CE format under the S-DCI mechanism. Figure 2 As shown, there are two subscripts i and j under the TCI state ID. i identifies the codepoint of the 3-bit TCIfield in the DCI corresponding to this TCI state ID. For example, i is 0, which corresponds to codepoint 000; i is 1, which corresponds to codepoint 001... etc. The subscript j identifies that this TCI state ID is the jth one among at least one TCI state ID corresponding to the i-th codepoint. For example, j is 1, which identifies the first one; j is 2, which identifies the second one. If the subscript is 0 or 1, it identifies the first TCIstate ID corresponding to codepoint 000. Figure 2As shown in Figure 1, under the S-DCI mechanism, each codepoint can correspond to at most two TCI states, that is, corresponding to different TRPs.

[0111] In the M-DCI mechanism, some CORESETs correspond to CORESETPoolIndex 0, while others correspond to CORESETPoolIndex 1. Each codepoint in the TCI field of DCI signaling can correspond to at most one TCI state. The TCI states corresponding to codepoints in the TCI field of CORESETs with different CORESETPoolIndex are determined by different MAC CEs. In the M-DCI mechanism, the MAC CE contains the CORESETPoolIndex and up to eight TCI states to be activated. Figure 3 Figure 1 shows a schematic diagram of the MAC CE format under the M-DCI mechanism. Figure 3 As shown, the MAC CE includes CORESETPoolIndex. The MAC CE indicates the TCI state corresponding to the codepoint of the TCI field of the DCI of at least one CORESET included in the CORESETPoolIndex. Figure 3 Many Ts are given in i , i identifies the TCI state ID in RRC signaling, if T iIf the bit position of is 1, it indicates that the TCI state ID is activated. For example, for CORESETPoolIndex 0, MAC CE activates TCI state#0, TCI state#4, TCI state#5, TCI state#12, TCI state#14, TCI state#26, TCI state#34, and TCI state#40, which correspond to codepoints 000, 001, 010, 011, 100, 101, 110, and 111 of the TCI field of the DCI of CORESET#0 and CORESET#1 (the CORESETPoolIndex of these two CORESETs is 0), respectively. For example, for CORESETPoolIndex1, MAC CE activates TCIstate#70, TCI state#74, TCI state#75, TCI state#82, TCI state#84, TCI state#96, TCIstate#104, and TCI state#108, which correspond to the codepoints of the TCI field of the DCI of CORESET#2 and CORESET#3 (the CORESETPoolIndex of these two CORESETs is 1), respectively.

[0112] When the CORESETPoolIndex of the CORESETs corresponding to multiple linked SS sets used for PDCCH repetition transmission is different, how to configure the TCI state corresponding to the codepoint of the TCI field in the DCI carried by the PDCCH candidates in the multiple linked SS sets, whether to use the S-DCI mechanism or the M-DCI mechanism, is a problem that needs to be solved.

[0113] The embodiments of the present disclosure provide a TCI state determination method to provide an indication of an activated TCI state corresponding to a codepoint included in a TCI field in a DCI when the CORESETPoolIndex of the CORESETs corresponding to two PDCCH candidates for PDCCH repetition are different.

[0114] Figure 4 FIG. 1 is a flow chart showing a method for determining a TCI state according to an exemplary embodiment. Figure 4 As shown, the TCI status determination method is executed by the terminal and includes the following steps.

[0115] In step S11, first configuration information is received, where the first configuration information is used to configure at least two SS sets having a link relationship, and CORESETPoolIndex of CORESETs corresponding to two of the at least two SS sets are different.

[0116] In the embodiment of the present disclosure, the two SS sets having a linked relationship can be understood as two PDCCH candidates with the same PDCCH candidate index in the two SS sets being used to send one DCI, or can be understood as two SS sets being used for PDCCH repetition.

[0117] In step S12, it is determined that the MAC CE to be received is the first MAC CE.

[0118] The first MAC CE is used to indicate at least one TCI state corresponding to each codepoint in at least one codepoint, the at least one codepoint is carried in the TCI field of DCI, and the DCI is transmitted by PDCCH candidates in at least two SSsets having a linked relationship.

[0119] In the embodiment of the present disclosure, when the CORESETPoolIndex of the CORESETs corresponding to multiple linked SS sets used for PDCCH repetition transmission is different, the TCI state corresponding to the codepoint included in the TCI field in the DCI is indicated through the first MAC CE.

[0120] The embodiment of the present disclosure will hereinafter describe the process of determining the first MAC CE.

[0121] In one implementation, the network device may be configured with configuration information indicating the first MAC CE, hereinafter referred to as second configuration information.

[0122] Figure 5 FIG. 1 is a flow chart of a method for determining a first MAC CE according to an exemplary embodiment. Figure 5 As shown, the following steps are included.

[0123] In step S21, second configuration information is determined.

[0124] In step S22, based on the second configuration information, it is determined that the MAC CE to be received is the first MAC CE.

[0125] In the embodiment of the present disclosure, the second configuration information is configured by the network device and is used to indicate the first MAC CE. The terminal receives the second configuration information sent by the network device to determine the first MAC CE.

[0126] The second configuration information indicates at least one of the following: a specified index value of CORESETPoolIndex included in the MAC CE; a specified bit included in the MAC CE.

[0127] In one implementation, if the MAC CE received by the terminal satisfies at least one of the following A and B indicated by the second configuration information, it is determined that the MAC CE to be received is the first MAC CE:

[0128] A: The CORESETPoolIndex included in the MAC CE has a specified index value.

[0129] B: The MAC CE includes the specified bit.

[0130] In one example, the designated index value may be the CORESETPoolIndex of the CORESET corresponding to the SS set that has no link relationship with any other SS set, hereinafter referred to as the first index value. For example, the first index value may be 0 or 1.

[0131] In another example, the specified index value may also be a CORESETPoolIndex of a CORESET corresponding to an SSset that has no link relationship with any other SS set, which is hereinafter referred to as the second index value. For example, the second index value may be a new CORESETPoolIndex assigned to two SS sets that have a link relationship. For example, the second index value may be 2. When the CORESET associated with any one of the two SS sets that have a link relationship also includes an independent SS set, the CORESETPoolIndex of the CORESET is still 0 or 1, while the CORESETPoolIndex of the two SS sets that have a link relationship is 2. An independent SS set is an SS set that has no link relationship with any other SS set.

[0132] In the embodiment of the present disclosure, when the CORESETPoolIndex in the MAC CE is a specified index value, such as 0 or 1 or the newly introduced 2, the MAC CE is the first MAC CE. This method can be understood as corresponding to Figure 3 MAC CE in M-DCI mode is shown.

[0133] The designated bit may be used to indicate whether the MAC CE is the first MAC CE.

[0134] In one embodiment, the first configuration information configures a group of at least two linked SS sets, and the designated bit is used to indicate whether the MAC CE to be received is the first MAC CE. In one example, if there is only one group of two linked SS sets for PDCCH repetition, the designated bit used to indicate the first MAC CE can simply indicate yes or no.

[0135] In another embodiment, the first configuration information configures multiple groups of at least two SS sets with a link relationship, and the designated bit is used to indicate the group identifier of the group to which the at least two SS sets with a link relationship belong. The group identifier is determined by radio resource control (RRC) signaling configuration or based on the SSset with the smallest SS set ID in the SS set group, or based on the CORESET with the smallest CORESET ID of the CORESET group corresponding to the SS set group. In one example, if there are multiple groups of two SS sets with a link relationship for PDCCH repetition, the designated bit used to indicate the first MACCE needs to indicate the group identifier of a group of SS sets with a link relationship.

[0136] In the embodiment of the present disclosure, when the MAC CE includes a designated bit for indicating the first MAC CE, the method of determining that the MAC CE is the first MAC CE may be corresponding to Figure 2 On the other hand, the first MAC CE in the embodiment of the present disclosure can be designed as a newly introduced MAC CE. In the newly introduced MAC CE, it can be Figure 2 The CORESETPoolIndex is introduced in the MAC CE shown in . When CORESETPoolIndex is 0 or 1, only one TCI state is activated for each codepoint. When CORESETPoolIndex is 2, two TCI states can be activated for each codepoint. This newly introduced MAC CE design can be understood as a MAC CE for linked SS sets. In the disclosed embodiment, the designated bit can also be the CORESETPoolIndex corresponding to the CORESET. For example, the CORESETPoolIndex corresponding to the first SS set is 2, the CORESETPoolIndex corresponding to the second SS set is 3, and so on.

[0137] The second configuration information involved in the TCI status determination method provided in the embodiments of the present disclosure can, on the one hand, be determined based on RRC signaling. That is, the terminal determines the first MAC CE based on the second configuration information carried in the RRC signaling. For example, the network instructs the terminal through RRC signaling that when the CORESETPoolIndex in the MAC CE is a specified index value, such as 0 or 1, or the newly introduced value 2, the MAC CE is the first MAC CE. The network instructs the terminal through RRC signaling that the MAC CE includes a specified bit, which is used to indicate whether the MAC CE is the first MAC CE.

[0138] Alternatively, the second configuration information mentioned above in the TCI status determination method provided in the embodiments of the present disclosure may be determined based on a default rule, i.e., the terminal determines the first MAC CE based on the protocol default second configuration information. For example, when the CORESETPoolIndex in the MAC CE is 0 or 1, or the newly introduced value 2, the MAC CE is the first MAC CE. Alternatively, when the MAC CE includes a designated bit indicating yes, the MAC CE is the first MAC CE; or when the MAC CE includes a designated bit indicating the group identifier of the SS set group, the MAC CE is the first MAC CE.

[0139] In the TCI status determination method provided by the embodiment of the present disclosure, the terminal may determine that the MAC CE to be received is the first MAC CE based on a default rule.

[0140] The default rule may include one of the following instructions:

[0141] A: The CORESETPoolIndex in the media access control unit is the CORESETPoolIndex value of the CORESET corresponding to the SS set with the smallest SS set identifier among at least two SS sets;

[0142] B: The CORESETPoolIndex in the media access control unit is the CORESETPoolIndex value corresponding to the CORESET with the smallest CORESET identifier among the CORESETs corresponding to at least two SS sets;

[0143] C: The CORESETPoolIndex value in the media access control element is at least one of a first index value and a second index value, wherein the first index value is 0 or 1, and the second index value is a newly introduced CORESETPoolIndex value of 2.

[0144] In the embodiment of the present disclosure, the terminal may determine the first MAC CE based on the second configuration information and / or a default rule.

[0145] Furthermore, in an embodiment of the present disclosure, the terminal may subsequently receive a first MAC CE, where the first MAC CE is used to indicate a maximum of one TCI state corresponding to each codepoint in at least one codepoint, or to indicate a maximum of two TCI states corresponding to each codepoint in at least one codepoint, so as to determine the activated TCI state corresponding to the codepoint included in the TCI field in the DCI based on the received first MAC CE.

[0146] Furthermore, the terminal may receive DCI and determine a codepoint included in the TCI field in the DCI, hereinafter referred to as a first codepoint. Based on the correspondence between the TCI state indicated by the first MAC CE and the codepoint, the terminal may determine the TCI state corresponding to the first codepoint, and thereby obtain an activated TCIstate corresponding to the codepoint included in the TCI field in the DCI.

[0147] Figure 6 FIG. 1 is a flow chart of a method for determining a TCI state according to an exemplary embodiment. Figure 6 As shown, the TCI status determination method is executed by the terminal and includes the following steps.

[0148] In step S31, a first MAC CE is received. The first MAC CE is used to indicate a maximum of one TCI state corresponding to each codepoint in at least one codepoint, or is used to indicate a maximum of two TCI states corresponding to each codepoint in at least one codepoint.

[0149] In step S32, DCI is received, and the first codepoint included in the TCI field in the DCI is determined.

[0150] In step S33, based on the correspondence between the TCI state indicated by the first MAC CE and the codepoint, the TCI state corresponding to the first codepoint is determined.

[0151] For example, the first MAC CE is used to indicate at most one TCI state corresponding to each codepoint in at least one codepoint, which can be based on Figure 3The M-DCI mechanism shown in FIG. 1 determines the activated TCI state corresponding to the codepoint contained in the TCI field in the DCI. For another example, the first MAC CE is used to indicate the maximum two TCI states corresponding to each codepoint in at least one codepoint, which can be based on Figure 2 The M-DCI mechanism shown determines the activated TCI state corresponding to the codepoint contained in the TCI field in the DCI.

[0152] In one embodiment, the first MAC CE is used to indicate at least two TCI states corresponding to at least one codepoint among the at least one codepoint, where each of the at least two TCI states is used for uplink transmission and / or downlink transmission. That is, the at least two TCI states are both used for downlink, or the at least two TCI states are both used for uplink, or some of the at least two TCI states are used for uplink and some for downlink, or the at least two TCI states are used for both uplink and downlink.

[0153] It can be understood that in the embodiment of the present disclosure, the downlink includes a downlink channel and / or a downlink signal. The downlink channel includes at least one of the following: a terminal-dedicated PDCCH (UE dedicated PDCCH), a non-UEdedicated PDCCH (non-UEdedicated PDCCH), a terminal-dedicated PDSCH (UE dedicated PDSCH), a non-UEdedicated PDSCH (non-UEdedicated PDSCH), and a physical broadcast channel (PBCH). The downlink signal includes at least one of the following: SSB, a channel state information reference signal (CSI reference signal, CSI-RS) (used for channel state information (CSI) measurement, and / or, for beam management), a tracking reference signal (TRS), a phase reference signal (PRS), and a demodulation reference signal (DMRS). The downlink signal can be periodic, semi-persistent, or non-periodic.

[0154] The uplink includes downlink channels and / or uplink signals. The uplink channel includes at least one of the following: physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), physical random access channel (PRACH). The uplink signal includes at least one of the following: sounding reference signal (SRS), DMRS. SRS is used for positioning, and / or for beam management, and / or for codebook / non-codebook based channel measurement or antenna switching. The uplink signal can be periodic, semi-persistent or non-periodic.

[0155] Based on the same concept, an embodiment of the present disclosure further provides a TCI status determination method, which is executed by a network device.

[0156] Figure 7 FIG. 1 is a flow chart of a method for determining a TCI state according to an exemplary embodiment. Figure 7 As shown, the TCI status determination method is executed by the network device and includes the following steps.

[0157] In step S41, first configuration information is sent, where the first configuration information is used to configure at least two SS sets having a link relationship, and CORESETPoolIndex of CORESETs corresponding to two of the at least two SS sets are different.

[0158] In step S42, a first MAC CE is sent, where the first MAC CE is used to indicate at least one TCI state corresponding to each codepoint in at least one codepoint, where the at least one codepoint is carried in a TCI field of a DCI, and the DCI is transmitted by PDCCH candidates in at least two linked SS sets.

[0159] In one implementation, the network device may send second configuration information, where the second configuration information is used to indicate the first MAC CE.

[0160] The second configuration information indicates at least one of the following: a specified index value of CORESETPoolIndex included in the MAC CE; a specified bit included in the MAC CE.

[0161] In one embodiment, the designated index value includes a first index value or a second index value. The first index value is the CORESETPoolIndex of the CORESET corresponding to the SS set that has no link relationship with any other SS set. For example, the first index value may be 0 or 1. The second index value is different from the CORESETPoolIndex of the CORESET corresponding to the SS set that has no link relationship with any other SS set. For example, the second index value may be 2.

[0162] When the CORESET associated with any one of the two linked SS sets also contains an independent SS set, the CORESETPoolIndex of the CORESET is still 0 or 1, while the CORESETPoolIndex of the two linked SS sets is 2. An independent SS set is an SS set that has no link relationship with any other SS set.

[0163] In one embodiment, the designated bit is used to indicate at least one of the following:

[0164] The first configuration information configures a group of at least two SS sets with a link relationship, and the designated bit is used to indicate whether the MAC CE to be received is the first MAC CE; the first configuration information configures multiple groups of at least two SS sets with a link relationship, and the designated bit is used to indicate the group identifier of the group to which the at least two SS sets with a link relationship belong.

[0165] In the embodiment of the present disclosure, when the MAC CE includes a designated bit for indicating the first MAC CE, the method of determining that the MAC CE is the first MAC CE may be corresponding to Figure 2 On the other hand, the first MAC CE in the embodiment of the present disclosure can be designed as a newly introduced MAC CE. In the newly introduced MAC CE, it can be Figure 2The CORESETPoolIndex is introduced in the MAC CE shown in . When CORESETPoolIndex is 0 or 1, only one TCI state is activated for each codepoint. When CORESETPoolIndex is 2, two TCI states can be activated for each codepoint. This newly introduced MAC CE design can be understood as a MAC CE for linked SS sets. In the disclosed embodiment, the designated bit can also be the CORESETPoolIndex corresponding to the CORESET. For example, the CORESETPoolIndex corresponding to the first SS set is 2, the CORESETPoolIndex corresponding to the second SS set is 3, and so on.

[0166] In one implementation, the network device may send the second configuration information based on RRC signaling.

[0167] In one embodiment, the first MAC CE is used to indicate a maximum of one TCI state corresponding to each codepoint in at least one codepoint, or is used to indicate a maximum of two TCI states corresponding to each codepoint in at least one codepoint.

[0168] In one embodiment, the first MAC CE is used to indicate at least two TCI states corresponding to at least one codepoint among the at least one codepoint; each TCI state in the at least two TCI states is used for uplink transmission and / or downlink transmission. That is, the at least two TCI states are both used for downlink, or the at least two TCI states are both used for uplink, or some of the at least two TCI states are used for uplink and some for downlink, or the at least two TCI states are used for both uplink and downlink.
