As shown in Figure 1C, in a far-field communication scenario, the beam directed to the terminal is a two-dimensional (2D) directional beam pointing toward the target terminal. For any path in multipath propagation, the time and phase of the beam reaching the terminal's receiving antenna array are equally spaced.

[0109] In some embodiments, for a terminal in a near-field communication scenario, the electromagnetic waves received by the terminal are spherical waves. Figure 1D is a schematic diagram of near-field beam propagation according to an embodiment of the present disclosure. As shown in Figure 1D, in a near-field communication scenario, the beam targeted at the terminal is a three-dimensional (3D) beam that surrounds the target terminal. For any path in multipath propagation, the time and phase of the beam arriving at the terminal's receiving antenna array are no longer equidistant.

[0110] That is, for a far-field terminal, the directions from multiple ports to the terminal are the same, while for a near-field terminal, the directions from different ports to the terminal are different.

[0111] For near-field or far-field communication scenarios, it is assumed that the network device has 32 transmission beam directions. For far-field communication scenarios, it is only necessary to send 32 reference signal resources based on 32 beam directions at any port. For near-field communication scenarios, the first beam direction (one of the 32 beam directions) sent by the network device at the first port and the direction of the first beam sent by the network device at the second port have different distances to the terminal. Therefore, the network device needs to send 32 beam directions on each port.

[0112] Understandably, if traditional beam management is used, network devices need to transmit reference signals for beam measurement using a single port. Consequently, terminal scanning time increases exponentially with the number of ports, resulting in significant resource overhead. Therefore, to reduce this resource overhead, communication is typically performed using multi-port reference signal resources.

[0113] In the traditional fifth-generation mobile networks (5G) New Radio (NR) communication system, each reference signal can only have one Transmission Configuration Indicator State (TCI) state, and the channel can have a maximum of two TCI states. However, in large-scale antenna scenarios, different antenna groups can correspond to different simulated beams. Therefore, even reference signals, such as multi-port reference signals, can correspond to multiple TCI states. How to configure reference signals corresponding to multiple TCI states is a problem that needs to be solved.

[0114] FIG2 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a resource configuration method for a communication system 100, the method comprising:

[0115] Step S2101 : The network device 102 sends second configuration information to the terminal 101 .

[0116] In some embodiments, the terminal 101 receives second configuration information sent by the network device 102 .

[0117] It should be noted that the second configuration information is used to configure a reference signal for beam measurement. After measuring the reference signal for beam measurement, terminal 101 reports it to network device 102, thereby enabling network device 102 to select the port corresponding to the reference signal that meets the requirements as the TCI state. In other words, the second configuration information can be understood as being used to obtain a reference signal corresponding to the TCI state and to configure a reference signal resource for beam measurement.

[0118] In some embodiments, the second configuration information is used to configure or indicate N reference signal resource sets, or to configure or indicate second reference signal resources including N ports, where N is an integer greater than or equal to 2.

[0119] It should be noted that the reference signal corresponding to the N reference signal resource sets configured or indicated by the second configuration information is a reference signal used for beam measurement, and the configured second reference signal resource is also a reference signal used for beam measurement.

[0120] In some embodiments, the terminal performs beam reporting based on the beam group based on the second configuration information.

[0121] In some embodiments, the terms “beam report based on beam group”, “beam group report”, “beam group measurement report”, “beam report” and the like can be used interchangeably.

[0122] It can be understood that after the terminal 101 performs beam measurement based on the configured reference signal, it can form a corresponding measurement report (that is, a beam report based on the beam group) for reporting to the network device 102, so that the network device 102 can select the port corresponding to the reference signal that meets the requirements (for example, the quality parameters meet the requirements) based on the beam report and configure it through the TCI state.

[0123] In some embodiments, the beam report includes at least one beam group, and the two reference signal resources contained in at least one beam group correspond to different reference signal resource sets, or the at least two ports contained in at least one beam group correspond to different port groups or different ports.

[0124] It is understandable that in order to ensure normal communication transmission, the terminal 101 needs to be able to receive multiple TCI states corresponding to the reference signal simultaneously. In order to enable the terminal 101 to receive multiple TCI states simultaneously, the terminal 101 needs to report to the network device 102 which beams can be used for simultaneous reception. For example, in the related art, when the terminal reports a reference signal resource group (group) that can be received simultaneously, and only two reference signal resource identifications (IDs) are included, the network device is informed that the beams sent by the network device corresponding to the two reference signal resources can be received simultaneously by the terminal, or the network device is informed that the transmit beams corresponding to the two reference signal resources can be sent simultaneously by the terminal. Therefore, for beam reporting, it is necessary to include at least two reference signal resources corresponding to different reference signal resource sets in the beam group, or to include at least two ports corresponding to different port groups or at least two different ports in a beam group, so as to inform the network device 102 that the reference signal resources and / or beams corresponding to the port (group) can be sent simultaneously and / or received simultaneously by the terminal 101.

[0125] For example, the beam report includes reference signal resource a# and reference signal resource b#. Reference signal resource a# corresponds to reference signal resource set A#, and reference signal resource b# corresponds to reference signal resource set B#. Terminal 101 reports the beam report to network device 102, thereby informing network device 102 that terminal 101 can simultaneously receive and / or transmit the beam corresponding to reference signal resource a# and the beam corresponding to reference signal resource b#.

[0126] For another example, a beam report includes port #1 and port #2. Terminal 101 reports this beam report to network device 102, thereby informing network device 102 that terminal 101 can simultaneously receive and / or transmit the beam corresponding to port #1 and the beam corresponding to port #2. Optionally, port #1 corresponds to the first port group, and port #2 corresponds to the second port group. Alternatively, the protocol does not configure a correspondence between port groups and port #1 and port #2.

[0127] In some embodiments, for each beam group in the beam report, at least one of the following is included: K second reference signal resource identifiers; L port identifiers; M port group identifiers; quality parameters, where K is an integer less than or equal to N, L is an integer less than or equal to N, and M is an integer less than or equal to N, the K second reference signal resource identifiers come from different reference signal resource sets among the N reference signal resource sets, and the L port identifiers come from different port groups among the N port groups.

[0128] It is understandable that the quality parameter includes, for example: Layer 1 Reference Signal Received Power (L1-RSRP) and / or Layer 1 Signal-to-noise And Interference Ratio (L1-SINR).

[0129] In some embodiments, the quality parameter may correspond to a reference signal resource identifier, a port identifier, and a port group identifier. That is, the quality parameter may be understood as: a quality parameter corresponding to the reference signal resource identifier, a quality parameter corresponding to the port identifier corresponding to the reference signal resource identifier, and a quality parameter corresponding to the port group identifier corresponding to the reference signal resource identifier.

[0130] Based on this, each beam group in the beam report may include at least one of the following: K second reference signal resource identifiers and L1-RSRPs corresponding to the K second reference signal resource identifiers; K second reference signal resource identifiers and L1-SINRs corresponding to the K second reference signal resource identifiers; K port identifiers and L1-RSRPs corresponding to the L port identifiers; L port identifiers and L1-SINRs corresponding to the L port identifiers; M port group identifiers and L1-RSRPs corresponding to the M port identifiers; M port group identifiers and L1-SINRs corresponding to the M port identifiers.

[0131] In this way, network device 102 can determine the quality parameter information and corresponding reference signal resource in the report based on the beam report, and can then select a reference signal resource whose quality parameter meets the preset requirements. In addition, when faced with a reference signal resource with multiple ports (or port groups), the quality parameter corresponding to the port (or port group) can also be determined.

[0132] In some embodiments, the second configuration information is further used to configure at least one of the following: configuring and reporting a beam group corresponding to uplink communication transmission; configuring and reporting a beam group corresponding to downlink communication transmission.

[0133] Optionally, if the second configuration information does not indicate, the terminal 101 may report in the beam report whether each beam group is used for uplink communication transmission, for downlink communication transmission, or for both uplink and downlink communication transmission.

[0134] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0135] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0136] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0137] In some embodiments, terms such as "synchronization signal (SS)", "synchronization signal block (SSB)", and "reference signal (RS)" may be used interchangeably.

[0138] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.

[0139] Step S2102 , terminal 101 sends a beam report to network device 102 .

[0140] In some embodiments, the network device 102 receives the beam report sent by the terminal 101.

[0141] It can be understood that the contents included in the beam report have been explained in the relevant embodiments of step S2101 and will not be repeated here.

[0142] In some embodiments, after receiving the beam report, the network device 102 may select the port corresponding to the reference signal that meets the preset requirements in the beam report as the port corresponding to the TCI state, and configure corresponding TCI states for other reference signals based on this.

[0143] Step S2103 , the network device 102 sends first configuration information to the terminal 101 .

[0144] In some embodiments, the terminal 101 receives first configuration information sent by the network device 102 .

[0145] In some embodiments, the first configuration information is used to perform first reference signal resource configuration, wherein the first reference signal resource is a multi-port reference signal resource, and among the multiple ports of the first reference signal resource, at least two ports correspond to different TCI states.

[0146] In some embodiments, the first configuration information is Radio Resource Control (RRC) signaling.

[0147] In some embodiments, the first reference signal resource includes: a Channel State Information Reference Signal (CSI-RS) or a Demodulation Reference Signal (DMRS).

[0148] In some embodiments, the first reference signal resource may be at least one of a demodulation reference signal (DMRS) of a physical downlink control channel (PDCCH), a DMRS of a physical downlink shared channel (PDSCH), a DMRS of a physical uplink control channel (PUCCH), and a DMRS of a physical uplink shared channel (PUSCH).

[0149] In some embodiments, “multi-port first reference signal resource” and “first reference signal resource” may be interchangeable.

[0150] It should be noted that at least two of the multiple ports correspond to different TCI states, which means that the TCI states used for transmission ultimately corresponding to the two ports are different, and the multiple candidate TCI states or TCI state lists corresponding to the configuration process can be the same or different.

[0151] The following describes different TCI configuration processes to help you understand the different TCI states that the two ports ultimately correspond to for transmission:

[0152] For example, consider the TCI state configuration process based on RRC signaling and a medium access control element (MAC CE). RRC configures the TCI state list, while the MAC CE activates the TCI state for transmission corresponding to each port. The TCI state ultimately corresponding to the two ports is the TCI state activated via the MAC CE.

[0153] For another example, consider the TCI state configuration process based on RRC, MAC CE, and Downlink Control Information (DCI). RRC configures the TCI state list, while MAC CE activates the correspondence between multiple candidate TCI states and the codepoints in the TCI indication field in the DCI. The DCI further indicates the codepoints in the TCI indication field. The TCI state corresponding to the codepoint indicated by the DCI is the TCI state ultimately used for transmission.

[0154] For another example, taking the configuration process of the unified TCI state as an example, after the unified TCI state corresponding to the first reference signal resource is configured based on the first configuration information, additional instructions (for example, other configuration information in addition to the first configuration information) are required to indicate which of the multiple unified TCI states each reference signal resource or resource set corresponds to, so that the two ports ultimately correspond to different TCI states for transmission.

[0155] In step S2104, the terminal 101 determines the TCI status.

[0156] In some embodiments, the terminal 101 determines a TCI state corresponding to the first reference signal resource.

[0157] In some embodiments, the terminal 101 determines the TCI state corresponding to the first reference signal resource, including determining at least one of the following:

[0158] -A) Determine the TCI status corresponding to the port.

[0159] -B) Determine the TCI status corresponding to the port group.

[0160] Regarding -A), in some embodiments, the TCI status corresponding to the port is determined. The TCI status corresponding to some ports may be determined, or the TCI status corresponding to all ports may be determined.

[0161] Determining the TCI status corresponding to some ports, for example, includes determining the TCI status indicated by the first configuration information corresponding to some ports, and / or determining the TCI status indicated by the third configuration information corresponding to some ports. For example, if the number of ports corresponding to a reference signal resource is a, but only ports with a number of ports b correspond to the TCI status indicated by the first configuration information (where a is an integer greater than or equal to 1, b is an integer greater than or equal to 1, and a is greater than b), then only the ports with the configured TCI status need to be determined, without having to determine the TCI status of all ports, thereby saving resource overhead.

[0162] Determining the TCI status corresponding to all ports includes, for example, determining the TCI status indicated by the first configuration information corresponding to each port, and / or determining the TCI status indicated by the third configuration information corresponding to each port. For example, if the number of ports corresponding to the reference signal resource is a, and all ports of the reference signal resource correspond to the TCI status indicated by the first configuration information (where a is an integer greater than or equal to 1), then determining the TCI corresponding to each port can clarify the TCI status corresponding to each port.

[0163] In some embodiments, the first configuration information and the third configuration information are not the same configuration information. For example, the first configuration information is only used to configure the time-frequency resources and reference signal identifiers, port identifiers or numbers corresponding to the reference signal resources, and the third configuration information is used to configure the TCI state. The TCI state is used to indicate at least one of the reference signal resource identifier, port identifier and port group identifier, as well as the mapping relationship between the TCI state and the port or port group corresponding to the reference signal resource in the first configuration information.

[0164] In some embodiments, the third configuration information may also be the first configuration information.

[0165] Optionally, the third configuration information may be, for example, at least one of the following: RRC signaling, MAC CE, and DCI.

[0166] Regarding -B), in some embodiments, the TCI status corresponding to the port group is determined. The TCI status corresponding to some ports may be determined, or the TCI status corresponding to all ports may be determined.

[0167] For determining the TCI status corresponding to some ports, for example, it includes: determining the TCI status indicated by the first configuration information corresponding to some ports, and / or determining the TCI status indicated by the third configuration information corresponding to some ports. For example, the number of port groups corresponding to the reference signal resource is a, but only the ports with the number of port groups b correspond to the TCI status indicated by the first configuration information (wherein a is an integer greater than or equal to 1, b is an integer greater than or equal to 1, and a is greater than b), then it is only necessary to determine the port groups in which the TCI status is configured, and there is no need to determine the TCI status of all port groups, thereby saving resource overhead. For example, the number of port groups corresponding to the reference signal resource is a, and all port groups of the reference signal resource correspond to the TCI status indicated by the first configuration information (wherein a is an integer greater than or equal to 1), then by determining the TCI corresponding to each port group, the TCI status corresponding to each port group can be clarified.

[0168] Determining the TCI status corresponding to all ports includes, for example, determining the TCI status indicated by the first configuration information corresponding to each port group and / or determining the TCI status indicated by the third configuration information corresponding to each port group. In some embodiments, determining the TCI status corresponding to a port group includes determining the TCI status corresponding to some port groups or determining the TCI status corresponding to each port group.

[0169] In some embodiments, determining TCI states corresponding to some port groups includes: determining port identifiers corresponding to some port groups based on default rules, or determining port identifiers corresponding to some port groups based on fourth configuration information.

[0170] In some embodiments, determining the TCI state corresponding to each port group includes: determining a port identifier corresponding to each port group based on a default rule, or determining a port identifier corresponding to each port group based on fourth configuration information.

[0171] Exemplarily, determining the port identifier corresponding to each port group based on the default rule may be at least one of the following:

[0172] 1) The port group corresponding to each port group identifier includes N ports with consecutive port identifiers (where N is an integer greater than or equal to 2).

[0173] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If the port groups are determined based on the continuity of the port identifiers, the eight ports are divided into two port groups. For example, the reference signal resource may have two port groups, port group A# and port group B#. Port group A# includes the following ports: port 0#, port 1#, port 2#, and port 3#. Port group B# includes the following ports: port 4#, port 5#, port 6#, and port 7#.

[0174] 2) The port group corresponding to each port group identifier includes N ports with equally spaced port identifiers.

[0175] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If the port group is determined based on the method of equally spaced port identifiers (for example, the interval is 1), the eight ports are determined as two port groups. For example, the reference signal resource may have two port groups, port group A# and port group B#. The ports in port group A# are: port 0#, port 2#, port 4#, and port 6#. The ports in port group B# are: port 1#, port 3#, port 5#, and port 7#.

[0176] 3) Determine, based on the protocol, the port identifiers contained in each port group in the port group corresponding to the port group identifier.

[0177] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If the port group is determined based on a protocol-determined method (for example, the protocol predetermines that multiple ports are divided into the same port group), for example, the reference signal resource may have two port groups, port group A# and port group B#. The ports in port group A# are: port 0#, port 1#, port 4#, and port 5#. The ports in port group B# are: port 2#, port 3#, port 6#, and port 7#.

[0178] In some embodiments, the correspondence relationship (correspondence relationship between ports and port groups) determined based on the fourth configuration information may be at least one of the following: the number of ports included in each port group; and port identifiers of ports included in each port group.

[0179] It should be noted that the fourth configuration information may be the first configuration information, or may be other configuration information except the first configuration information.

[0180] In some embodiments, if the port identifiers of the ports included in the port group corresponding to each port group identifier are continuous, the number of ports included in each port group can be configured through the fourth configuration information to achieve configuration of the port group, wherein the starting port identifier is determined by default.

[0181] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If it is known that the port identifiers of the ports included in each port group are consecutive, the starting port identifier of port group A is port 2#, and if the fourth configuration information configures the number of ports included in group A to be 3, then the ports included in port group A are: port 2#, port 3#, and port 4#.

[0182] In some embodiments, if the port identifiers included in the port group corresponding to each port group identifier are non-consecutive, the port identifiers in each port group are directly indicated by the second configuration information.

[0183] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If it is known that the port identifiers of the ports included in each port group are non-consecutive, the fourth configuration information can be used to indicate that the ports included in port group A are: port 2#, port 4#, and port 5# (or other combinations, etc.).

[0184] In some embodiments, the fourth configuration information may be information other than the first configuration information, or may be the first configuration information.

[0185] Thus, the correspondence between the port identifier and the port group identifier in the port information and how the correspondence between the two is determined can be clarified.

[0186] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0279] Figure 5 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a resource configuration method, which includes:

[0280] Step S5101: The network device sends first configuration information.

[0281] The optional implementation of step S5101 can refer to the optional implementation of step S2101, step S2102, step S2103 in Figure 2, and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0282] Step S5102: The terminal determines a transmission configuration indicator TCI state corresponding to the first reference signal resource.

[0283] In some embodiments, a transmission configuration indication TCI state corresponding to the first reference signal resource is determined based on the first configuration information, wherein the first reference signal resource is a reference signal resource of multiple ports, and among the multiple ports, at least two ports correspond to different TCI states.

[0284] The optional implementation of step S5101 can refer to the optional implementation of step S2104 in Figure 2, as well as other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0285] In some embodiments, the above method may also include the methods of the above-mentioned communication system side, terminal side, network device side, etc., which will not be repeated here.

[0286] In some embodiments, the embodiments of the present disclosure also propose a communication method, which enables a reference signal resource to be transmitted based on multiple transmit beams of a base station and / or multiple receive beams of a terminal, so that a near-field terminal can perform CSI measurement and feedback based on multiple transmit and receive beams based on a reference signal, thereby reducing signaling overhead and improving transmission performance.

[0287] In some embodiments, the terminal receives first configuration information, the first configuration information includes reference signal resource configuration information, the reference signal resource corresponds to multiple ports, the TCI state corresponding to the reference signal resource is determined, and at least two ports among the other multiple ports correspond to different TCI states.

[0288] In some embodiments, determining the TCI state corresponding to the reference signal resource includes first configuration information indicating or other configuration information indicating the TCI state corresponding to each port.

[0289] In some embodiments, determining the TCI state corresponding to the reference signal resource includes first configuration information indicating or other configuration information indicating the TCI state corresponding to each port group.

[0290] Optionally, the port identifiers included in each port group are determined in the following manners: based on a default rule, or based on configuration information.

[0291] Exemplarily, the default rule determination includes: each port group includes N consecutive ports; each port group includes N ports that are equally spaced; or the ports included in the port group are specified by the protocol.

[0292] If the default rule is used, then the reference signal resources or / channels do not need to occupy all ports in each port group. For example, if a port group contains ports 0, 1, and 2, the reference signal and channel can only occupy port 0, or port 0 and 1.

[0293] Exemplarily, the determination based on the configuration information includes: if the included ports are continuous: configuring the number of ports included in each port group, wherein the starting port identifier is determined by default; if not continuous, directly indicating the port identifier (index) of the ports included in each port group.

[0294] It is understandable that since one reference signal (and / or channel) corresponds to multiple TCI states, and these multiple TCI states need to be received simultaneously by the terminal, the terminal is required to report which beams the terminal can receive simultaneously. Traditionally, the reference signal resource set that the terminal reports can be received simultaneously only includes two reference signal resource IDs, that is, the terminal only tells the base station which two reference signal resources correspond to the base station's transmit beams that the terminal can receive simultaneously, or tells the base station which two reference signal resources correspond to the transmit beams that the terminal can send simultaneously. Moreover, the reference signal resource ID is reported in the beam group. Due to large-scale antennas, the base station may be able to send more transmit beams at the same time, and the reference signal resources used for beam measurement can be sent based on more ports, and different ports can also correspond to different transmit beams. Therefore, it is necessary to enhance the beam group report (group based beam report). Including the following enhancements.

[0295] In some embodiments, the terminal receives second configuration information, the second configuration information includes reference signal resource configuration information, the reference signal resource configuration information includes N reference signal resource sets, or one reference signal resource includes N port groups, where N is an integer greater than or equal to 2.

[0296] In some embodiments, based on the second configuration information, the terminal performs a beam group report, each beam group contains a maximum of N reference signal resource IDs or N port IDs, and the L1-RSRP / L1-SINR corresponding to the corresponding reference signal resource ID, or the L1-RSRP / L1-SINR corresponding to the corresponding port ID, where the N reference signal resources come from different reference signal resource sets, or the N ports come from different port groups.

[0297] In some embodiments, the second configuration information may further configure the beam group for uplink, downlink, or both. If the second configuration information does not indicate, the terminal may report that each beam group can be used for uplink, downlink, or both.

[0298] In some embodiments, the reference signal resource includes a CSI-RS or a DMRS.

[0299] In some embodiments, the first configuration information is RRC, and the other configuration information is RRC, MAC CE or DCI.

[0300] It should be noted that at least two of the multiple ports correspond to different TCI states, which refers to the TCI states that the two ports ultimately correspond to for transmission. For example, the TCI state configuration process is RRC+MAC CE, RRC configures the TCI state list, and MAC CE activates the TCI state for transmission corresponding to each port. The TCI state ultimately used for transmission here is the TCI state activated by MAC CE. For example, the TCI state configuration process is RRC+MAC CE+DCI, RRC configures the TCI state list, and MAC CE activates the correspondence between multiple TCI states and the codepoint of the TCI indication field in the DCI, and the DCI further indicates the codepoint of the TCI indication field. Then the TCI state corresponding to the codepoint indicated by the DCI is the TCI state ultimately used for transmission. There's also a unified TCI state process. While the two aforementioned processes only indicate the unified TCI state, the reference signal resources in the aforementioned embodiment require additional signaling to indicate which of multiple unified TCI states each reference signal resource or resource set corresponds to. This additional signaling can also be RRC, MAC CE, or DCI, and it's this additional signaling that determines the final TCI state used for transmission. This means that in the TCI state configuration process for two ports, the corresponding TCI states in the previous processes can be the same, but the final TCI states used for transmission can be different.

[0301] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
