[0204] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0205] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0206] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0207] This disclosure provides a communication method, apparatus, and storage medium. In scenarios where network devices and terminals can simultaneously transmit and receive via uplink and downlink subbands within a single TDD carrier, a scheme for determining the TCI state and power control parameters of the physical channel is provided.

[0208] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0209] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminal equipment and network equipment. The systems may also include a core network component, such as the Evolved Packet Core (EPC) or the 5G Core Network (5GC).

[0210] The terminal devices involved in the embodiments of this disclosure can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in 5G or 6G systems, the terminal device may be called User Equipment (UE). Wireless terminal devices can be USB storage devices, other personal computer memory devices, and dongles. They can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) telephones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminal devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this disclosure.

[0211] The network device involved in this disclosure can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in this disclosure can be an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, network testing equipment, etc., and is not limited in this disclosure. In some network architectures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated.

[0212] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0213] In signal transmission, if the radio channel attributes of one antenna port can be derived from the radio channel attributes of another antenna port, then these two antenna ports are quasi-co-located (QCL). The radio channel attributes of the antenna ports may include, for example, Doppler shift, Doppler spread, average delay, delay spread, spatial reception parameters, etc. Higher layers can configure the QCL relationship through TCI states, thereby enabling beam indication.

[0214] Currently, a unified TCI (Unified TCI) framework has been introduced into MIMO transmission, using a common TCI to indicate downlink QCL information and / or uplink transmit spatial filter information. Furthermore, Unified TCI is supported for multiple transmit-receive point (M-TRP) scenarios. Specifically, the TCI state pool is configured by Radio Resource Control (RRC) messages, and eight TCI states are activated via Medium Access Control-Control Element (MAC CE) signaling. Each TCI state corresponds to one or two TRPs, and the Unified TCI field in the Downlink Control Information (DCI) indicates the update of the corresponding TRP's TCI state.

[0215] Under the Unified TCI framework, when M-TRP is supported, for a Physical Downlink Shared Channel (PDSCH) scheduled by a single DCI (S-DCI), the presence of a TCI selection field in the scheduled DCI can be configured via RRC messages. If it is included, the TCI selection field indicates the association between the PDSCH and the TCI state. If the DCI format 1_1 or DCI format 1_2 does not contain a TCI selection field, the association between the PDSCH and the TCI state is determined by two joint TCI states or two downlink TCI states if certain conditions are met; otherwise, the association between the PDSCH and the TCI state is determined by the first joint TCI state or the first downlink TCI state. For PDSCH with multi-DCI (M-DCI) scheduling, if the conditions are met, the joint TCI state or downlink TCI state associated with the CORESETPoolIndex (i.e., CORESET pool index) associated with the corresponding control resource set (CORESET) is used; otherwise, the TCI state associated with CORESETPoolIndex being 0 is used for PDSCH reception.

[0216] For the Physical Uplink Control Channel (PUCCH), the association between each resource (group) and TCI state can be configured via RRC messages. For the Physical Uplink Shared Channel (PUSCH), there are two cases: For PUSCH in S-DCI mode, the association between PUSCH and TCI state is indicated by the Sound Reference Signal (SRS) resource set indication field. If the DCI does not contain an SRS resource set indication field, the association between PUSCH and TCI state is determined by RRC message configuration or a predefined method. For PUSCH in M-DCI mode, if there is DCI scheduling, the TCI state associated with the CORESETPoolIndex associated with CORESET is used; otherwise, the TCI state corresponding to each resource (group) is configured via RRC.

[0217] In the above embodiments, the TCI state of the physical channel under the Unified TCI framework was determined. Currently, SBFD technology has been proposed, allowing network devices to simultaneously transmit and receive within a single TDD carrier using both uplink and downlink subbands. SBFD will be described below with reference to the accompanying drawings.

[0218] 5G NR supports two duplex communication modes: TDD and Frequency Division Duplex (FDD). TDD mode allows for transmission and reception at different times on the same frequency channel (carrier), using time to differentiate uplink and downlink transmission resources. FDD mode allows for simultaneous transmission and reception on different frequency channels, using frequency to differentiate uplink and downlink transmission resources.

[0219] SBFD mode refers to the ability of network devices to transmit and receive simultaneously within a single TDD carrier using different subbands, with no overlap between the subbands used for transmission and reception.

[0220] SBFD mode is implemented based on SBFD symbols. An SBFD symbol is a symbol that simultaneously contains uplink subbands for uplink transmission and downlink subbands for downlink transmission; that is, a symbol that includes both uplink and downlink frequency domain resources in the frequency domain. Currently, SBFD symbols can be configured in downlink symbols or flexible symbols configured in TDD-UL-DL-ConfigCommon. For subband full-duplex systems, the currently supported subband configurations mainly include two types: SBFD subband configuration 1 and SBFD subband configuration 2. These two subband configurations are described below with reference to Figure 1.

[0221] Figure 1 illustrates the subband configurations supported in a subband full-duplex system. As shown in Figure 1, two subband configuration methods are illustrated: SBFD subband configuration 1 and SBFD subband configuration 2. For an SBFD symbol, it includes one SBFD time slot in the time domain and uplink and downlink subbands in the frequency domain.

[0222] Please refer to Figure 1. For SBFD subband configuration 1, it uses the {DUD} mode (D represents downlink and U represents uplink), that is, one SBFD symbol contains one uplink subband and two downlink subbands. The uplink subband is located in the center of the carrier bandwidth, and the two downlink subbands are located on both sides of the carrier bandwidth. For SBFD subband configuration 2, it uses the {DU} mode, that is, one SBFD symbol contains one uplink subband and one downlink subband. The uplink subband is located on one side of the carrier bandwidth, and the downlink subband is located on the other side of the carrier bandwidth.

[0223] The above embodiments, in conjunction with Figure 1, illustrate the SBFD symbol subband configuration. During the transmission of the physical channel, the symbol type of the symbol at the physical channel transmission location can include SBFD symbols and / or non-SBFD symbols. In this scenario, it is necessary to determine the first TCI state and / or the first power control parameter of the physical channel in order to transmit or receive the physical channel. The scheme of the embodiments of this disclosure will be described below with reference to Figure 2.

[0224] Figure 2 is a flowchart of a communication method provided in an embodiment of this disclosure. As shown in Figure 2, the method includes:

[0225] S21, based on the symbol type of the symbol where the physical channel transmission location is located, determine the first TCI state and / or the first power control parameter of the physical channel.

[0226] The symbol type includes SBFD symbols and / or non-SBFD symbols; the first TCI state and the first power control parameter are used to transmit the physical channel, or the first TCI state is used to receive the physical channel.

[0227] The solutions disclosed in this embodiment can be applied to wireless communication systems, involving interaction between terminals and network devices, and transmission of physical channels between terminals and network devices.

[0228] The execution entity of each embodiment of this disclosure can be a terminal or a network device. The physical channel can be an uplink transmission physical channel, such as PUCCH, PUSCH, etc., and the physical channel can be a downlink transmission physical channel, such as Physical Downlink Control Channel (PDCCH), PDSCH, etc.

[0229] When the executing entity is a terminal, if the physical channel is an uplink transmission physical channel, the terminal sends the physical channel to the network device by determining the first TCI state and / or the first power control parameter of the physical channel; if the physical channel is a downlink transmission physical channel, the terminal receives the physical channel sent by the network device by determining the first TCI state of the physical channel.

[0230] Optionally, the terminal in each embodiment of this disclosure can be an SBFD terminal. The SBFD terminal is a terminal that supports SBFD. A terminal that supports SBFD is one that knows the SBFD subband configuration, or knows that the access network device performs SBFD operations, or is a later version of the terminal; a terminal that does not support SBFD is one that does not know the SBFD subband configuration, or does not know that the access network device performs SBFD operations, or is an earlier version of the terminal.

[0231] When the executing entity is a network device, if the physical channel is an uplink transmission physical channel, the network device receives the physical channel sent by the terminal by determining the first TCI state of the physical channel; if the physical channel is a downlink transmission physical channel, the network device sends the physical channel to the terminal by determining the first TCI state of the physical channel.

[0232] The number of symbols at the physical channel transmission location can be one or more. For any given symbol, its symbol type is either SBFD (Single-Side Variable Frequency) or non-SBFD. An SBFD symbol refers to a symbol that simultaneously contains an uplink subband for uplink transmission and a downlink subband for downlink transmission; that is, a symbol that includes both uplink and downlink frequency domain resources in the frequency domain. Its subband configuration can be seen in the example in Figure 1, and will not be repeated here. The time-frequency domain location information of an SBFD symbol is configured to the terminal by the network device. A non-SBFD symbol, on the other hand, refers to a symbol that is not configured as an SBFD symbol, that is, a symbol that contains one type of frequency domain resource (uplink or downlink frequency domain resource) in the frequency domain.

[0233] In one possible implementation, different TCI states can be configured for different symbol types. Once the symbol type of the symbol where the physical channel transmission location is located is determined, the first TCI state of the physical channel can be determined.

[0234] For example, if the symbol type of the symbols where the physical channel transmission location is located is SBFD symbol, then the TCI state configured for SBFD symbol can be determined as the first TCI state; if the symbol type of the symbols where the physical channel transmission location is located is non-SBFD symbol, then the TCI state configured for non-SBFD symbol can be determined as the first TCI state.

[0235] For example, if the number of symbols of type SBFD in the symbols where the physical channel transmission location is located is greater than or equal to the number of symbols of type non-SBFD, then the TCI state configured for SBFD symbols can be determined as the first TCI state; if the number of symbols of type SBFD in the symbols where the physical channel transmission location is located is less than the number of symbols of type non-SBFD, then the TCI state configured for non-SBFD symbols can be determined as the first TCI state.

[0236] For example, if the symbol type of the Kth symbol in the symbol where the physical channel transmission location is located is an SBFD symbol, then the TCI state configured for the SBFD symbol can be determined as the first TCI state; if the symbol type of the Kth symbol in the symbol where the physical channel transmission location is located is a non-SBFD symbol, then the TCI state configured for the non-SBFD symbol can be determined as the first TCI state. K can take values ​​of 1, 2, ..., M, where M is the number of symbols in the physical channel transmission location and M is a positive integer.

[0237] In one possible implementation, different power control parameters can be configured for different symbol types. Once the symbol type of the symbol where the physical channel transmission location is located is determined, the first power control parameter of the physical channel can be determined.

[0238] For example, if the symbol type of the symbols where the physical channel transmission location is located is SBFD symbol, then the power control parameter configured for SBFD symbol can be determined as the first power control parameter; if the symbol type of the symbols where the physical channel transmission location is located is non-SBFD symbol, then the power control parameter configured for non-SBFD symbol can be determined as the first power control parameter.

[0239] For example, if the number of symbols of type SBFD in the symbols where the physical channel transmission location is located is greater than or equal to the number of symbols of type non-SBFD, then the power control parameter configured for SBFD symbols can be determined as the first power control parameter; if the number of symbols of type SBFD in the symbols where the physical channel transmission location is located is less than the number of symbols of type non-SBFD, then the power control parameter configured for non-SBFD symbols can be determined as the first power control parameter.

[0240] For example, if the symbol type of the Kth symbol in the symbol where the physical channel transmission location is located is an SBFD symbol, then the power control parameter configured for the SBFD symbol can be determined as the first power control parameter; if the symbol type of the Kth symbol in the symbol where the physical channel transmission location is located is a non-SBFD symbol, then the power control parameter configured for the non-SBFD symbol can be determined as the first power control parameter. K can take values ​​of 1, 2, ..., M, where M is the number of symbols in the physical channel transmission location and M is a positive integer.

[0241] The communication method provided in this disclosure involves a terminal determining a first TCI state and / or a first power control parameter of a physical channel based on the symbol type of the symbol at the physical channel transmission location. The symbol type includes SBFD symbols and / or non-SBFD symbols. The first TCI state and the first power control parameter are used to transmit the physical channel, or the first TCI state is used to receive the physical channel. For scenarios where network devices can simultaneously transmit and receive via uplink and downlink subbands within a single TDD carrier, a scheme is provided to determine the first TCI state and / or the first power control parameter of a physical channel based on the symbol type of the symbol at the physical channel transmission location, thereby enabling the transmission or reception of the physical channel.

[0242] Based on any of the above embodiments, the solutions of the present disclosure embodiments will be further described below with reference to the accompanying drawings.

[0243] In one possible implementation, the first TCI state of the physical channel is determined based on the symbol type of the symbol where the physical channel transmission location is located, and the second TCI state corresponding to each symbol type. The second TCI state corresponding to each symbol type includes the second TCI state corresponding to SBFD symbols and the second TCI state corresponding to non-SBFD symbols.

[0244] Optionally, the second TCI state corresponding to each symbol type is determined based on the DCI within the third TCI state group corresponding to each symbol type. For any symbol type, the second TCI state corresponding to that symbol type can be determined within the third TCI state group based on the TCI field in the DCI.

[0245] Optionally, the third TCI state group corresponding to each symbol type is configured by the MAC CE. There are two ways to configure the third TCI state group corresponding to each symbol type in the MAC CE. The first way is that each MAC CE is configured with a third TCI state group corresponding to one symbol type, and the corresponding symbol type is indicated in the MAC CE. The second way is that a single MAC CE is configured with a third TCI state group corresponding to two symbol types.

[0246] Accordingly, MAC CE may include at least one of the following:

[0247] The first MAC CE is used to configure the third TCI state group corresponding to the SBFD symbol;

[0248] The second MAC CE is used to configure the third TCI state group corresponding to non-SBFD symbols;

[0249] The third MAC CE is used to configure the third TCI state group corresponding to SBFD symbols and the third TCI state group corresponding to non-SBFD symbols.

[0250] The first method is used to configure the third TCI state group for the first MAC CE and the second MAC CE, that is, each MAC CE is configured with a third TCI state group corresponding to a symbol type.

[0251] The first MAC CE may include a specific bit to indicate that the third TCI state group configured by the first MAC CE is the third TCI state group corresponding to the SBFD symbol. For example, the first MAC CE may be configured with 8 third TCI state groups corresponding to the SBFD symbol, and then the DCI may indicate the second TCI state corresponding to the SBFD symbol in these 8 third TCI state groups.

[0252] The second MAC CE may include a specific bit to indicate that the third TCI state group configured by the second MAC CE is the third TCI state group corresponding to non-SBFD symbols. For example, the second MAC CE may be configured with 8 third TCI state groups corresponding to non-SBFD symbols, and then the DCI indicates the second TCI state corresponding to the non-SBFD symbols in these 8 third TCI state groups.

[0253] The following section describes the first method for configuring the third TCI state group corresponding to each symbol type in MAC CE, using specific examples. It should be noted that in the following embodiments, the example uses a MAC CE configuration of up to eight third TCI state groups.

[0254] Figure 3 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 3, the example illustrates the format of the MAC CE when each MAC CE is configured with a third TCI state group corresponding to a symbol type. In Figure 3, an octet (Oct) represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of N+3 bytes.

[0255] As shown in Figure 3, the symbol type indicator bit in the MAC CE indicates whether the third TCI state group configured for the MAC CE corresponds to an SBFD symbol or a non-SBFD symbol. If the third TCI state group configured for the MAC CE corresponds to an SBFD symbol, then the MAC CE is the first MAC CE; if the third TCI state group configured for the MAC CE corresponds to a non-SBFD symbol, then the MAC CE is the second MAC CE.

[0256] As shown in Figure 3, the serving cell identifier is used to indicate the serving cell of the MAC CE application, the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application, and the uplink BWP identifier is used to indicate the uplink BWP of the MAC CE application (this field is reserved if the uplink and downlink are jointly indicated by TCI).

[0257] As shown in Figure 3, P i This indicates whether each TCI code point corresponds to one or multiple TCI states, if P i Setting it to 1 indicates that TCI code point i contains both downlink TCI state and uplink TCI state. If P i Setting it to 0 indicates that TCI code point i corresponds to only one of the downlink TCI state, joint TCI state, and uplink TCI state. In the example in Figure 3, a maximum of 8 third TCI state groups corresponding to symbol types can be configured, each P i This corresponds to a third TCI state group.

[0258] As shown in Figure 3, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, which has a total of N, where N is a positive integer. For each TCI state ID, the MAC CE includes an uplink / downlink indicator bit (i.e., D / U in Figure 3), used to indicate whether the TCI state indicated by that TCI state ID is an uplink TCI state, a downlink TCI state, or a combined TCI state. If the MAC CE is configured with D third TCI state groups, since each TCI code point corresponds to one or two TCI states, N is greater than or equal to D and less than or equal to 2*D.

[0259] Figure 4 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 4, the example illustrates the format of the MAC CE when each MAC CE is configured with a third TCI state group corresponding to a symbol type. In Figure 4, an Oct represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of N+3 bytes.

[0260] As shown in Figure 4, the symbol type indicator bit in the MAC CE indicates whether the third TCI state group configured for the MAC CE corresponds to an SBFD symbol or a non-SBFD symbol. If the third TCI state group configured for the MAC CE corresponds to an SBFD symbol, then the MAC CE is the first MAC CE; if the third TCI state group configured for the MAC CE corresponds to a non-SBFD symbol, then the MAC CE is the second MAC CE.

[0261] As shown in Figure 4, the serving cell identifier is used to indicate the serving cell of the MAC CE application, and the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application.

[0262] In the example in Figure 4, this MAC CE is used for uplink and downlink joint TCI indication, targeting a multi-TRP scenario. In the example in Figure 4, up to eight third TCI state groups corresponding to the symbol type can be configured, each group (F... i,1 ,F i,2 This corresponds to a third TCI state group. As shown in Figure 4, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, which has a total of N states, where N is a positive integer.

[0263] F i,j Indicates whether the j-th TCI state of TCI code point i exists, if F i,j Setting it to 1 indicates that the j-th TCI state of TCI code point i exists, if F i,j Setting it to 0 indicates that the j-th TCI state of TCI code point i does not exist. Specifically, when j is 1, the j-th TCI state of TCI code point i corresponds to the TCI state of the first TRP; when j is 2, the j-th TCI state of TCI code point i corresponds to the TCI state of the second TRP. Alternatively, when j is 1, the j-th TCI state of TCI code point i corresponds to the TCI state of the second TRP; when j is 2, the j-th TCI state of TCI code point i corresponds to the TCI state of the first TRP.

[0264] Figure 5 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 5, the example illustrates the format of the MAC CE when each MAC CE is configured with a third TCI state group corresponding to a symbol type. In Figure 5, an Oct represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of N+6 bytes.

[0265] As shown in Figure 5, the symbol type indicator bit in the MAC CE indicates whether the third TCI state group configured for the MAC CE corresponds to an SBFD symbol or a non-SBFD symbol. If the third TCI state group configured for the MAC CE corresponds to an SBFD symbol, then the MAC CE is the first MAC CE; if the third TCI state group configured for the MAC CE corresponds to a non-SBFD symbol, then the MAC CE is the second MAC CE.

[0266] As shown in Figure 5, the serving cell identifier is used to indicate the serving cell of the MAC CE application, the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application, and the uplink BWP identifier is used to indicate the uplink BWP of the MAC CE application.

[0267] In the example in Figure 5, this MAC CE is used for uplink and downlink independent TCI indication, targeting a multi-TRP scenario. In the example in Figure 5, up to eight third TCI state groups corresponding to the symbol type can be configured, each group (F i,1 ,F i,2 ,S i,1 ,S i,2 This corresponds to a third TCI state group. As shown in Figure 5, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, which has a total of N states, where N is a positive integer.

[0268] As shown in Figure 5, F i,j Indicates whether the j-th downlink TCI state of TCI code point i exists, if F i,j Setting it to 1 indicates that the j-th downlink TCI state of TCI code point i exists, if F i,jSetting it to 0 indicates that the j-th downlink TCI state of TCI code point i does not exist. Here, the first downlink TCI state of TCI code point i represents the downlink TCI state corresponding to the first TRP, and the second downlink TCI state of TCI code point i represents the downlink TCI state corresponding to the second TRP; or, the first downlink TCI state of TCI code point i represents the downlink TCI state corresponding to the second TRP, and the second downlink TCI state of TCI code point i represents the downlink TCI state corresponding to the first TRP.

[0269] As shown in Figure 5, S i,j Indicates whether the j-th uplink TCI state of TCI code point i exists, if S i,j Setting it to 1 indicates that the j-th uplink TCI state of TCI code point i exists, if S i,j Setting it to 0 indicates that the j-th uplink TCI state of TCI code point i does not exist. Here, the first uplink TCI state of TCI code point i represents the uplink TCI state corresponding to the first TRP, and the second uplink TCI state of TCI code point i represents the uplink TCI state corresponding to the second TRP; or, the first uplink TCI state of TCI code point i represents the uplink TCI state corresponding to the second TRP, and the second uplink TCI state of TCI code point i represents the uplink TCI state corresponding to the first TRP.

[0270] It should be noted that in Figures 3 to 5, the first bit in MAC CE is used as the sign type indicator bit. This is just one example of how to indicate the corresponding sign type. Other reserved bits R can also be used as sign type indicator bits.

[0271] In the above embodiments, a first method of configuring the third TCI state group corresponding to each symbol type for the MAC CE was described, namely, the case where each MAC CE is configured with a third TCI state group corresponding to one symbol type. In this case, the MAC CE includes a first MAC CE and / or a second MAC CE, and the DCI can be used to indicate the second TCI state in the third TCI state group configured for the MAC CE.

[0272] Accordingly, when the MAC CE includes a first MAC CE and / or a second MAC CE, the DCI satisfies any one of the following conditions 1.1 to 1.3:

[0273] 1.1 The DCI includes a first TCI field and a second TCI field. The first TCI field is used to indicate the second TCI state corresponding to the SBFD symbol, and the second TCI field is used to indicate the second TCI state corresponding to the non-SBFD symbol.

[0274] The first TCI field in the DCI can be used in the third TCI state group corresponding to the SBFD symbol configured in the first MAC CE to indicate the second TCI state corresponding to the SBFD symbol. The first TCI field can be an indicator field for the TCI code point. By using the TCI code point i indicated by the first TCI field, the second TCI state corresponding to the SBFD symbol can be determined in the first MAC CE.

[0275] The second TCI field in the DCI can be used in the third TCI state group corresponding to the non-SBFD symbol configured in the second MAC CE to indicate the second TCI state corresponding to the non-SBFD symbol. The second TCI field can be an indicator field for the TCI code point. By using the TCI code point i indicated by the second TCI field, the second TCI state corresponding to the non-SBFD symbol in the second MAC CE can be determined.

[0276] Since the DCI includes a first TCI field and a second TCI field, a single DCI can indicate the second TCI state corresponding to an SBFD symbol and the second TCI state corresponding to a non-SBFD symbol.

[0277] 1.2 The DCI includes a third TCI field, which is used to indicate the second TCI state corresponding to the SBFD symbol, and to indicate the second TCI state corresponding to the non-SBFD symbol.

[0278] Since the MAC CEs for different symbol types are independent, the third TCI field in the DCI can determine the second TCI state corresponding to the SBFD symbol in the first MAC CE. That is, the second TCI state corresponding to the SBFD symbol is obtained by combining the DCI with the first MAC CE. The third TCI field in the DCI can also determine the second TCI state corresponding to non-SBFD symbols in the second MAC CE. That is, the second TCI state corresponding to non-SBFD symbols is obtained by combining the DCI with the second MAC CE.

[0279] In this method, a single DCI can indicate the second TCI state corresponding to an SBFD symbol and the second TCI state corresponding to a non-SBFD symbol.

[0280] 1.3 The DCI includes a fourth TCI field, which is used to indicate the second TCI state corresponding to the first symbol type. The first symbol type is determined based on the attribute information of the DCI.

[0281] The first symbol type is either an SBFD symbol or a non-SBFD symbol; that is, the DCI can be used to indicate the second TCI state corresponding to a certain first symbol type. The attribute information of the DCI determines whether the first symbol type is an SBFD symbol or a non-SBFD symbol.

[0282] When the first symbol type is SBFD symbol, the fourth TCI field is used to indicate the second TCI state corresponding to the SBFD symbol in the third TCI state group corresponding to the SBFD symbol; when the first symbol type is non-SBFD symbol, the fourth TCI field is used to indicate the second TCI state corresponding to the non-SBFD symbol in the third TCI state group corresponding to the non-SBFD symbol.

[0283] Optionally, the DCI's attribute information includes at least one of the following (a)-(c):

[0284] (a) Symbol type of the search space (SS) where DCI is located.

[0285] Based on the symbol type of the SS where DCI is located, the first symbol type can be determined. The first symbol type is either an SBFD symbol or a non-SBFD symbol.

[0286] For example, if the symbol type of the SS where the DCI is located is SBFD symbol, then the first symbol type is determined to be SBFD symbol; if the symbol type of the SS where the DCI is located is not SBFD symbol, then the first symbol type is determined to be not SBFD symbol.

[0287] For example, if the core set in the SS containing the DCI can span different symbol types, the first symbol type can be determined based on the first symbol type of the core set in the SS containing the DCI. Specifically, if the first symbol type of the core set in the SS containing the DCI is an SBFD symbol, then the first symbol type is determined to be an SBFD symbol; if the first symbol type of the core set in the SS containing the DCI is a non-SBFD symbol, then the first symbol type is determined to be a non-SBFD symbol.

[0288] For example, if the core set in the SS containing the DCI can span different symbol types, the first symbol type can be determined based on the last symbol type of the core set in the SS containing the DCI. Specifically, if the last symbol type of the core set in the SS containing the DCI is an SBFD symbol, then the first symbol type is determined to be an SBFD symbol; if the last symbol type of the core set in the SS containing the DCI is not an SBFD symbol, then the first symbol type is determined to be a non-SBFD symbol.

[0289] (b) The symbol type of the symbol where the channel transmission location is scheduled by DCI.

[0290] Based on the symbol type of the symbol where the channel transmission location is scheduled by DCI, the first symbol type can be determined. The first symbol type is either an SBFD symbol or a non-SBFD symbol.

[0291] For example, if the symbol type of the symbol where the transmission location of the channel scheduled by the DCI is located is an SBFD symbol, then the first symbol type is determined to be an SBFD symbol; if the symbol type of the symbol where the transmission location of the channel scheduled by the DCI is located is a non-SBFD symbol, then the first symbol type is determined to be a non-SBFD symbol.

[0292] For example, if the symbol type of the symbol at the transmission location of the channel scheduled by the DCI includes SBFD symbols and non-SBFD symbols, the first symbol type can be determined based on the first symbol type of the symbol at the transmission location of the channel scheduled by the DCI. Specifically, if the first symbol type of the symbol at the transmission location of the channel scheduled by the DCI is an SBFD symbol, then the first symbol type is determined to be an SBFD symbol; if the first symbol type of the symbol at the transmission location of the channel scheduled by the DCI is a non-SBFD symbol, then the first symbol type is determined to be a non-SBFD symbol.

[0293] For example, if the symbol type of the symbol containing the transmission location of the channel scheduled by the DCI includes SBFD symbols and non-SBFD symbols, the first symbol type can be determined based on the last symbol type of the symbol containing the transmission location of the channel scheduled by the DCI. Specifically, if the last symbol type of the symbol containing the transmission location of the channel scheduled by the DCI is an SBFD symbol, then the first symbol type is determined to be an SBFD symbol; if the last symbol type of the symbol containing the transmission location of the channel scheduled by the DCI is a non-SBFD symbol, then the first symbol type is determined to be a non-SBFD symbol.

[0294] (c) The time slot number where DCI is located.

[0295] Based on the slot number of the DCI, the first symbol type can be determined, which is either an SBFD symbol or a non-SBFD symbol.

[0296] For example, if the slot number of the DCI is odd, the first symbol type is determined to be an SBFD symbol; if the slot number of the DCI is even, the first symbol type is determined to be a non-SBFD symbol.

[0297] For example, if the slot number of the DCI is odd, the first symbol type is determined to be a non-SBFD symbol; if the slot number of the DCI is even, the first symbol type is determined to be an SBFD symbol.

[0298] In the above embodiments, the first method of configuring the third TCI state group corresponding to each symbol type of the MAC CE was described. The second method of configuring the third TCI state group corresponding to each symbol type of the MAC CE is described below with specific examples. It should be noted that in the following embodiments, the example of configuring up to 8 third TCI state groups on the MAC CE is used.

[0299] Figure 6 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 6, the example illustrates the format of a MAC CE when configured with two symbol types corresponding to the third TCI state group. These two symbol types refer to SBFD symbols and non-SBFD symbols. In Figure 6, an Oct represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of N+3 bytes.

[0300] As shown in Figure 6, the serving cell identifier is used to indicate the serving cell of the MAC CE application, and the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application.

[0301] In the example of Figure 6, this MAC CE is used for uplink and downlink combined TCI indication. In the example of Figure 6, a maximum of eight third TCI state groups can be configured, each group (F i,1 ,F i,2 Each TCI state corresponds to a third TCI state group. As shown in Figure 6, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, which has a total of N states, where N is a positive integer.

[0302] As shown in Figure 6, F i,j Indicates whether the j-th TCI state of TCI code point i exists, if F i,j Setting it to 1 indicates that the j-th TCI state of TCI code point i exists, if F i,j Setting it to 0 indicates that the j-th TCI state of TCI code point i does not exist. Here, the first TCI state of TCI code point i represents the TCI state corresponding to a non-SBFD symbol, and the second TCI state of TCI code point i represents the TCI state corresponding to an SBFD symbol; or, the first TCI state of TCI code point i represents the TCI state corresponding to an SBFD symbol, and the second TCI state of TCI code point i represents the TCI state corresponding to a non-SBFD symbol.

[0303] Figure 7 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 7, the example illustrates the format of a MAC CE when configured with two symbol types corresponding to the third TCI state group. These two symbol types refer to SBFD symbols and non-SBFD symbols. In Figure 7, an Oct represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of M bytes.

[0304] As shown in Figure 7, the serving cell identifier is used to indicate the serving cell of the MAC CE application, and the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application.

[0305] In the example in Figure 7, this MAC CE is used for combined uplink and downlink TCI indication. In the example in Figure 7, up to eight third TCI state groups can be configured, each group (TCI state ID) i,1 TCI state ID i,2 Each TCI state corresponds to a third TCI state group. As shown in Figure 7, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, which has a total of N states, where N is a positive integer.

[0306] As shown in Figure 7, TCI state ID i,j This represents the j-th TCI state corresponding to TCI code point i. Specifically, the first TCI state of TCI code point i represents the TCI state corresponding to a non-SBFD symbol, and the second TCI state of TCI code point i represents the TCI state corresponding to an SBFD symbol; or, the first TCI state of TCI code point i represents the TCI state corresponding to an SBFD symbol, and the second TCI state of TCI code point i represents the TCI state corresponding to a non-SBFD symbol.

[0307] Figure 8 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 8, the example illustrates the format of a MAC CE when configured with two symbol types corresponding to the third TCI state group. These two symbol types refer to SBFD symbols and non-SBFD symbols. In Figure 8, an Oct represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of N+6 bytes.

[0308] As shown in Figure 8, the serving cell identifier is used to indicate the serving cell of the MAC CE application, the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application, and the uplink BWP identifier is used to indicate the uplink BWP of the MAC CE application.

[0309] In the example in Figure 8, this MAC CE is used for uplink and downlink independent TCI indication. In the example in Figure 8, a maximum of eight third TCI state groups can be configured, each group (F i,1 ,F i,2 ,S i,1 ,S i,2 Each TCI state corresponds to a third TCI state group. As shown in Figure 8, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, which has a total of N states, where N is a positive integer.

[0310] As shown in Figure 8, F i,j This indicates whether the j-th downlink TCI state corresponding to TCI code point i exists. If F i,j Setting it to 1 indicates that the j-th downlink TCI state of TCI code point i exists, if F i,j Setting it to 0 indicates that the j-th downlink TCI state of TCI code point i does not exist. Here, the first downlink TCI state of TCI code point i represents the downlink TCI state corresponding to a non-SBFD symbol, and the second downlink TCI state of TCI code point i represents the downlink TCI state corresponding to an SBFD symbol; or, the first downlink TCI state of TCI code point i represents the downlink TCI state corresponding to an SBFD symbol, and the second downlink TCI state of TCI code point i represents the downlink TCI state corresponding to a non-SBFD symbol.

[0311] S i,j This indicates whether the j-th uplink TCI state corresponding to TCI code point i exists. If S i,j Setting it to 1 indicates that the j-th uplink TCI state of TCI code point i exists, if S i,j Setting it to 0 indicates that the j-th uplink TCI state of TCI code point i does not exist. Here, the first uplink TCI state of TCI code point i represents the uplink TCI state corresponding to a non-SBFD symbol, and the second uplink TCI state of TCI code point i represents the uplink TCI state corresponding to an SBFD symbol; or, the first uplink TCI state of TCI code point i represents the uplink TCI state corresponding to an SBFD symbol, and the second uplink TCI state of TCI code point i represents the uplink TCI state corresponding to a non-SBFD symbol.

[0312] Figure 9 is a schematic diagram of a MAC CE provided in an embodiment of this disclosure. As shown in Figure 9, the example illustrates the format of a MAC CE when configured with two symbol types corresponding to the third TCI state group. These two symbol types refer to SBFD symbols and non-SBFD symbols. In Figure 8, an Oct represents a byte consisting of 8 bits, and R represents a placeholder, i.e., a reserved bit. The MAC CE comprises a total of M bytes.

[0313] As shown in Figure 9, the serving cell identifier is used to indicate the serving cell of the MAC CE application, the downlink BWP identifier is used to indicate the downlink BWP of the MAC CE application, and the uplink BWP identifier is used to indicate the uplink BWP of the MAC CE application.

[0314] In the example in Figure 9, this MAC CE is used for uplink and downlink independent TCI indication. In the example in Figure 9, the TCI state ID in the MAC CE indicates the TCI states contained in the third TCI state group, of which there are N, where N is a positive integer. A maximum of 8 third TCI state groups can be configured, each group (TCI state ID) i,1,1 TCI state ID i,1,2 TCI state ID i,2,1 TCI state ID i,2,2 This corresponds to a third TCI state group.

[0315] As shown in Figure 9, TCI state ID i,1,1 TCI state ID i,1,2 TCI state ID i,2,1 TCI state ID i,2,2 These represent the downlink TCI state of the non-SBFD symbol corresponding to TCI code point i, the downlink TCI state of the SBFD symbol corresponding to TCI code point i, the uplink TCI state of the non-SBFD symbol corresponding to TCI code point i, and the uplink TCI state of the SBFD symbol corresponding to TCI code point i, respectively.

[0316] In the above embodiments, a second method for configuring the MAC CE with third TCI state groups corresponding to each symbol type was described, namely, the case where one MAC CE is configured with third TCI state groups corresponding to two symbol types. In this case, the MAC CE includes a third MAC CE, and the DCI can be used to indicate the second TCI state in the third TCI state group configured by the third MAC CE. Each third TCI state group corresponds to one or two symbol types. When a third TCI state group corresponds to two symbol types, one TCI state in this third TCI state group is the TCI state corresponding to the SBFD symbol, and the other TCI state is the TCI state corresponding to the non-SBFD symbol. The DCI can indicate one of multiple third TCI state groups, thus the TCI state in the third TCI state group indicated by the DCI can be determined as the second TCI state corresponding to each symbol type.

[0317] The above embodiments describe how to determine the second TCI state corresponding to an SBFD symbol type and how to determine the second TCI state corresponding to a non-SBFD symbol type. For a physical channel, the first TCI state of the physical channel can be determined based on the symbol type of the symbol where the physical channel transmission location is located and the second TCI state corresponding to each symbol type.

[0318] Optionally, the first TCI state satisfies any one of the following conditions 2.1 to 2.3:

[0319] 2.1 When the symbol type of the symbol at the physical channel transmission location is SBFD symbol, the first TCI state is the second TCI state corresponding to the SBFD symbol.

[0320] If the symbol type of the symbol where the physical channel transmission location is located is SBFD symbol, then the second TCI state corresponding to the SBFD symbol can be selected as the first TCI state from the second TCI state corresponding to the SBFD symbol and the second TCI state corresponding to the non-SBFD symbol.

[0321] 2.2 When the symbol type of the symbol at the physical channel transmission location is non-SBFD symbol, the first TCI state is the second TCI state corresponding to the non-SBFD symbol.

[0322] If the symbol type of the symbol where the physical channel transmission location is located is non-SBFD symbol, then the second TCI state corresponding to the non-SBFD symbol can be selected as the first TCI state from the second TCI state corresponding to the SBFD symbol and the second TCI state corresponding to the non-SBFD symbol.

[0323] 2.3 When the symbol type of the symbol at the physical channel transmission location includes SBFD symbols and non-SBFD symbols, the first TCI state is the second TCI state determined based on the first rule.

[0324] If the symbol type of the symbol where the physical channel transmission location is located includes SBFD symbols and non-SBFD symbols, the first TCI state can be determined based on the first rule in the second TCI state corresponding to the SBFD symbol and the second TCI state corresponding to the non-SBFD symbol.

[0325] Optionally, the first rule is used to indicate at least one of (d)-(g) below:

[0326] (d) The first TCI state is the second TCI state corresponding to the first symbol type of the symbol where the physical channel transmission location is located.

[0327] The first symbol type refers to the symbol type of the first symbol in the symbols where the physical channel transmission location is located. The first symbol type is either an SBFD symbol or a non-SBFD symbol. If the first symbol type is an SBFD symbol, then the first TCI state is the second TCI state corresponding to the SBFD symbol; if the first symbol type is a non-SBFD symbol, then the first TCI state is the second TCI state corresponding to the non-SBFD symbol.

[0328] (e) The first TCI state is the second TCI state corresponding to the last symbol type of the symbol where the physical channel transmission location is located.

[0329] The last symbol type refers to the symbol type of the last symbol in the symbols of the physical channel transmission location. The last symbol type is either an SBFD symbol or a non-SBFD symbol. If the last symbol type is an SBFD symbol, then the first TCI state is the second TCI state corresponding to the SBFD symbol; if the last symbol type is a non-SBFD symbol, then the first TCI state is the second TCI state corresponding to the non-SBFD symbol.

[0330] (f) The first TCI state is the second TCI state corresponding to the SBFD symbol.

[0331] In other words, if the symbol type of the symbol at the physical channel transmission location includes SBFD symbols and non-SBFD symbols, then the second TCI state corresponding to the SBFD symbol is always determined as the first TCI state.

[0332] (g) The first TCI state is the second TCI state corresponding to the non-SBFD symbol.

[0333] In other words, if the symbol type of the symbol at the physical channel transmission location includes SBFD symbols and non-SBFD symbols, then the second TCI state corresponding to the non-SBFD symbol is always determined as the first TCI state.

[0334] By configuring different second TCI states for different symbol types, terminal / network devices can select the first TCI state from the second TCI states corresponding to SBFD symbols and the second TCI states corresponding to non-SBFD symbols based on the symbol type of the symbol where the physical channel transmission location is located, for sending or receiving physical channels, thereby improving system performance.

[0335] In the above embodiments, the method for determining the first TCI state of the physical channel was introduced. The following will introduce how to determine the first power control parameter of the physical channel.

[0336] In one possible implementation, the first power control parameter of the physical channel is determined based on the symbol type of the symbol where the physical channel transmission location is located, and the second power control parameter associated with the first TCI state. The second power control parameter associated with the first TCI state includes the second power control parameter corresponding to SBFD symbols and the second power control parameter corresponding to non-SBFD symbols.

[0337] Optionally, the second power control parameter corresponding to the SBFD symbol includes at least one of the following: a first path loss reference signal, a first target received power, a first path loss compensation factor, and a first closed-loop index.

[0338] Optionally, the second power control parameter corresponding to the non-SBFD symbol includes at least one of the following: second path loss reference signal, second target received power, second path loss compensation factor, and second closed-loop index.

[0339] The second power control parameter is configured by RRC for each TCI state.

[0340] The above embodiments describe how to determine the second power control parameter corresponding to the SBFD symbol type and how to determine the second power control parameter corresponding to the non-SBFD symbol type. For a physical channel, the first power control parameter of the physical channel can be determined based on the symbol type of the symbol where the physical channel transmission location is located and the second power control parameter associated with the first TCI state.

[0341] For an SBFD terminal, each TCI state is associated with two sets of power control parameters: one set corresponding to SBFD symbols and the other set corresponding to non-SBFD symbols. After determining the first TCI state of the physical channel, the second power control parameters associated with that first TCI state can be determined, including the second power control parameters corresponding to SBFD symbols and the second power control parameters corresponding to non-SBFD symbols. Then, based on the symbol type of the symbol where the physical channel transmission location is located and the second power control parameters associated with the first TCI state, the first power control parameter is determined.

[0342] Optionally, the first power control parameter satisfies any one of the following conditions 3.1 to 3.3:

[0343] 3.1 When the symbol type of the symbol at the physical channel transmission location is SBFD symbol, the first power control parameter is the second power control parameter corresponding to the SBFD symbol.

[0344] If the symbol type of the symbol where the physical channel transmission location is located is SBFD symbol, then the second power control parameter corresponding to the SBFD symbol can be selected as the first power control parameter from the second power control parameter corresponding to the SBFD symbol and the second power control parameter corresponding to the non-SBFD symbol.

[0345] 3.2 When all symbols at the physical channel transmission location are non-SBFD symbols, the first power control parameter is the second power control parameter corresponding to the non-SBFD symbol.

[0346] If the symbol type of the symbol where the physical channel transmission location is located is non-SBFD symbol, then the second power control parameter corresponding to the non-SBFD symbol can be selected as the first power control parameter from the second power control parameter corresponding to the SBFD symbol and the second power control parameter corresponding to the non-SBFD symbol.

[0347] 3.3 When the symbol type of the symbol at the physical channel transmission location includes SBFD symbols and non-SBFD symbols, the first power control parameter is the second power control parameter determined based on the second rule.

[0348] If the symbol type of the symbol where the physical channel transmission location is located includes SBFD symbols and non-SBFD symbols, the first power control parameter can be determined based on the second rule from the second power control parameter corresponding to the SBFD symbol and the second power control parameter corresponding to the non-SBFD symbol.

[0349] Optionally, the second rule is used to indicate at least one of the following (h)-(k):

[0350] (h) The first power control parameter is the second power control parameter corresponding to the first symbol type of the symbol where the physical channel transmission location is located.

[0351] The first symbol type refers to the symbol type of the first symbol in the symbols where the physical channel transmission location is located. The first symbol type is either an SBFD symbol or a non-SBFD symbol. If the first symbol type is an SBFD symbol, then the first power control parameter is the second power control parameter corresponding to the SBFD symbol; if the first symbol type is a non-SBFD symbol, then the first power control parameter is the second power control parameter corresponding to the non-SBFD symbol.

[0352] (i) The first power control parameter is the second power control parameter corresponding to the last symbol type of the symbol where the physical channel transmission location is located.

[0353] The last symbol type refers to the symbol type of the last symbol in the symbols where the physical channel transmission location is located. The last symbol type is either an SBFD symbol or a non-SBFD symbol. If the last symbol type is an SBFD symbol, then the first power control parameter is the second power control parameter corresponding to the SBFD symbol; if the last symbol type is a non-SBFD symbol, then the first power control parameter is the second power control parameter corresponding to the non-SBFD symbol.

[0354] (j) The first power control parameter is the second power control parameter corresponding to the SBFD symbol.

[0355] In other words, if the symbol type of the symbol where the physical channel transmission location is located includes SBFD symbols and non-SBFD symbols, then the second power control parameter corresponding to the SBFD symbol will always be determined as the first power control parameter.

[0356] (k) The first power control parameter is the second power control parameter corresponding to a non-SBFD symbol.

[0357] In other words, if the symbol type of the symbol at the physical channel transmission location includes SBFD symbols and non-SBFD symbols, then the second power control parameter corresponding to the non-SBFD symbol will always be determined as the first power control parameter.

[0358] It should be noted that if the first power control parameter is the second power control parameter corresponding to the SBFD symbol, and the second power control parameter corresponding to the SBFD symbol includes some items in the first path loss reference signal, the first target received power, the first path loss compensation factor, and the first closed-loop index, then other parameters can use the second power control parameter corresponding to a non-SBFD symbol by default.

[0359] For example, the second power control parameters corresponding to an SBFD symbol include the first target received power and the first closed-loop index, while the second power control parameters corresponding to a non-SBFD symbol include: the second path loss reference signal, the second target received power, the second path loss compensation factor, and the second closed-loop index. If the first power control parameter is the same as the second power control parameter corresponding to an SBFD symbol, then the power control parameters used when transmitting or receiving the physical channel include the first target received power, the first closed-loop index, the second path loss reference signal, and the second path loss compensation factor.

[0360] If the first power control parameter is the second power control parameter corresponding to a non-SBFD symbol, and the second power control parameter corresponding to a non-SBFD symbol includes some items in the second path loss reference signal, the second target received power, the second path loss compensation factor, and the second closed-loop index, then the other parameters can use the second power control parameter corresponding to the SBFD symbol by default.

[0361] For example, the second power control parameters corresponding to non-SBFD symbols include the second target received power and the second closed-loop index, while the second power control parameters corresponding to SBFD symbols include: the first path loss reference signal, the first target received power, the first path loss compensation factor, and the first closed-loop index. If the first power control parameter is the second power control parameter corresponding to a non-SBFD symbol, then the power control parameters used when transmitting or receiving the physical channel include the second target received power, the second closed-loop index, the first path loss reference signal, and the first path loss compensation factor.

[0362] By configuring different second power control parameters for different symbol types, terminal / network devices can select the first power control parameter from the second power control parameters corresponding to SBFD symbols and the second power control parameters corresponding to non-SBFD symbols based on the symbol type of the symbol where the physical channel transmission location is located, for sending or receiving physical channels, thereby improving system performance.
