The network-side device may include one or more TRPs (transmit and / or reception points). In some scenarios (such as high-speed rail scenarios), these TRPs may be remote radio head (RRH) nodes.

[0182] In order to facilitate a clearer understanding of the various embodiments of the present disclosure, some relevant knowledge is first introduced.

[0183] In a wireless communication system, such as a New Radio (NR) system (also known as a new air interface system), the UE needs to determine a path loss (PL) based on a downlink signal, and then determine the transmission power of the uplink signal based on the path loss. Path loss is usually referred to as path loss. Uplink signals, such as the Physical Uplink Shared Channel (PUSCH), the Sounding Reference Signal (SRS) or the Physical Random Access Channel (PRACH). The path loss of all uplink transmissions is determined based on the Pathloss Reference Signal (PL-RS). The types of PL-RS include synchronization signal / physical broadcast channel block (SSB) and periodically transmitted channel state information reference signal (CSI-RS).

[0184] Taking PUSCH as an example, the transmission power of PUSCH is determined based on the path loss. b,f,c (q d ) is calculated based on PL b,f,c (q d ) = reference signal power (referenceSignalPower) – higher layer filtered reference signal received power (higher layer filtered RSRP), where b is the index of the activated BWP, f is the carrier identifier, c is the cell identifier, and q d It is the identifier of the reference signal used to determine the path loss. ReferenceSignalPower is determined by the high-level signaling ss-PBCH-BlockPower or ss-PBCH-BlockPower+powerControlOffsetSS (the default value is 0dB). RSRP is the UE based on q dThe RSRP of the corresponding reference signal is determined. If the UE is not configured to receive periodic CSI-RS, referenceSignalPower is determined based on the ss-PBCH-BlockPower sent by the base station through higher-layer signaling. If the UE is configured to receive periodic CSI-RS, referenceSignalPower is determined based on the ss-PBCH-BlockPower or powerControlOffsetSS, which provides the offset of the CSI-RS transmission power relative to the SSB transmission power. If powerControlOffsetSS is not provided to the UE, the UE assumes the offset value is 0dB.

[0185] Due to the limitation of UE transmission power, the UL transmission performance of UE at the edge of the cell is usually far inferior to the DL transmission performance. In a distributed Multiple Input Multiple Output (MIMO) system, the distributed deployment of multiple sites can reduce path loss, so that the UL transmission can achieve performance similar to that of the DL. Dense site deployment will cause the downlink coverage of multiple sites to overlap severely. On the one hand, in order to reduce the downlink interference between sites with overlapping coverage, and on the other hand, for the consideration of network energy saving in low-load scenarios, for a terminal, the network side equipment may adopt an asymmetric uplink and downlink multiple transmission reception point (M-TRP, Multiple transmit and / or reception point) transmission mode, or an asymmetric uplink and downlink M-TRP scenario. The so-called asymmetric uplink and downlink M-TRP transmission mode refers to the asymmetry between the number of TRPs (transmit and / or reception point) for uplink reception and the number of TRPs for downlink reception. For example, the downlink uses one TRP for transmission, but the uplink can be received through two TRPs, that is, asymmetric DL sTRP / UL mTRP). These TRPs can be TRPs within a cell or TRPs between cells. Optionally, the asymmetry between UL and DL TRPs is viewed from the perspective of the UE, that is, for the same network, some UEs use asymmetric uplink and downlink M-TRP transmission methods, while some UEs have the same number of TRPs for uplink and downlink transmission. In particular, the network side deploys some TRPs that only perform uplink reception. These TRPs can be sites without DL transmission channels, or sites with DL transmission channels, but the downlink channels are closed within a given time. The TRP in the present invention can also be called a site, access point (AP), etc.

[0186] In this asymmetric uplink and downlink M-TRP transmission, the uplink transmission towards the site that does not perform downlink transmission does not have the downlink path loss reference signal of the corresponding site. One method to determine the corresponding path loss is to determine the path loss based on the path loss reference signal from the DL TRP (i.e., the TRP that can perform downlink transmission), and the base station then sends a path loss offset to the UE for path loss adjustment between sites. For uplink transmission towards the TRP that can have downlink transmission, the corresponding path loss should be determined based on the path loss reference signal, and there is no need to adjust it based on the path loss offset. That is, in the asymmetric uplink and downlink M-TRP transmission scenario, some uplink transmissions need to determine the path loss based only on the path loss reference signal, and some uplink transmissions need to determine the path loss based on the path loss reference signal and the path loss offset.

[0187] In existing technologies, the base station and UE do not directly exchange information about the association between uplink transmissions and TRPs. Therefore, in asymmetric downlink and uplink multi-TRP scenarios, the base station needs to indicate to the UE which uplink transmissions use path loss offset to determine path loss, and which do not. There is no specific solution in existing technologies.

[0188] In a multi-carrier scenario, the UE communicates with multiple carriers (or component carriers). There may be differences in uplink and downlink transmission capabilities between different carriers. In this case, it is possible that some carriers can perform both uplink and downlink transmission, while some carriers can only perform uplink transmission. In a multi-carrier scenario (also known as a carrier aggregation (CA) scenario), due to the asymmetry of uplink and downlink transmission carriers, the carrier that does not perform downlink transmission does not have a downlink path loss signal uploaded on the carrier. A method for determining the path loss corresponding to the uplink transmission for a carrier without downlink transmission (for example, carrier 1) is to determine the path loss corresponding to the uplink transmission based on a path loss reference signal from a DL carrier (i.e., a carrier that can perform downlink transmission) and a path loss offset (path loss offset corresponding to carrier 1) sent by the base station to the UE (i.e., the UE adjusts the path loss based on the path loss offset). For uplink transmission for a carrier with downlink transmission, the corresponding path loss should be determined based on the path loss reference signal, and no adjustment based on the path loss offset is required. That is, in scenarios where multiple carriers perform asymmetric uplink and downlink transmission, it is necessary for the uplink transmission corresponding to some carriers to determine path loss based solely on the path loss reference signal, while the uplink transmission corresponding to other carriers needs to determine path loss based on the path loss reference signal and path loss offset. In this scenario, the base station needs to indicate to the UE which uplink transmissions determine path loss based on the path loss offset and which uplink transmissions do not. There is no specific solution in the prior art. However, how to ensure that network-side equipment (e.g., base station) and terminals (e.g., UE) have consistent understanding of whether uplink transmission path loss is determined based on the path loss offset is a technical problem that needs to be solved urgently.

[0189] FIG1 is a flow chart of a method for determining path loss according to an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG1 , the method includes steps 101 to 102, wherein:

[0190] Step 101: Receive first information sent by a network-side device, where the first information includes information indicating whether to determine a path loss of a first signal based on a first path loss offset and / or indicating the first path loss offset.

[0191] It should be noted that the first information can be carried in one or more of Radio Resource Control (RRC) signaling, Media Access Control-Control Unit (MAC-Control Element, MAC-CE) or Downlink Control Information (DCI) signaling.

[0192] The first signal may include at least one of the following: PUSCH; Physical Uplink Control Channel (PUCCH); SRS; PRACH.

[0193] Optionally, the network-side device sends first information to the terminal, where the first information includes information indicating whether the path loss of the first signal is determined based on the first path loss offset and / or information indicating the first path loss offset. After receiving the first information sent by the network-side device, the terminal can determine, based on the first information, whether the path loss of the first signal is determined based on the first path loss offset, or determine the first path loss offset corresponding to the first signal, thereby achieving consistent understanding between the network-side device and the terminal regarding whether the path loss of uplink transmission is determined based on the path loss offset.

[0194] Optionally, the first path loss offset and / or the identifier corresponding to the first path loss offset is indicated by first information, or the first path loss offset and / or the identifier corresponding to the first path loss offset is indicated by indication information from a network-side device. The terminal determines the first path loss offset corresponding to the first signal based on the first information or the indication information.

[0195] For example, the first signal is a PUSCH (or, referred to as a PUSCH transmission, or referred to as a signal carried by a PUSCH), the first information is the configuration information of the PUSCH, and the first information includes information for indicating a path loss offset (for example, M bits are used to indicate a path loss offset from multiple path loss offsets, or information for indicating an identifier corresponding to a path loss offset). The network side device configures or indicates N (for example, N=4) path loss offsets for the UE. Then, for the PUSCH transmission, the information for indicating the path loss offset included in the configuration information of the PUSCH corresponding to the PUSCH transmission indicates that the network device configures or indicates one or more of the N path loss offsets for the UE, that is, the first path loss offset corresponding to the PUSCH.

[0196] Step 102: Perform a target operation according to the first information, the target operation including: determining a path loss of the first signal based on a path loss reference signal and the first path loss offset;

[0197] Alternatively, the path loss of the first signal is determined based on a path loss reference signal.

[0198] Optionally, when a first path loss offset corresponding to the first signal is determined based on the first information, the first information indicates a value of the first path loss offset.

[0199] When determining a first path loss offset corresponding to a first signal based on the first information, the first information does not directly indicate the value of the first path loss offset, but rather indicates an identifier corresponding to the first path loss offset. For example, the first information indicates the sequence number of the first path loss offset among multiple path loss offsets. For another example, the first information indicates a TCI state associated with the first path loss offset, and the UE determines the first path loss offset based on the TCI state associated with the first path loss offset. For another example, the first information indicates an SRS resource set associated with the first path loss offset, and the UE determines the first path loss offset based on the SRS resource set associated with the first path loss offset.

[0200] The network-side device may indicate the first path loss offset via RRC signaling, MAC-CE signaling, or DCI signaling. This signaling may be the same as or different from the signaling carrying the first information. Optionally, the network-side device directly indicates a value for the first path loss offset. Optionally, the network-side device indicates a value for determining the first path loss offset, and the terminal determines the first path loss offset by filtering or looking up the value indicated by the network-side device for determining the first path loss offset.

[0201] Optionally, performing the target operation according to the first information includes the following steps:

[0202] Step a: Based on the first information, determine whether to determine the path loss of the first signal based on the first path loss offset, or determine the first path loss offset corresponding to the first signal;

[0203] Step b: When the path loss of the first signal is determined based on the first path loss offset, the path loss of the first signal is determined based on a path loss reference signal and the first path loss offset.

[0204] In the case where the first information includes information indicating that the path loss is determined based on the first path loss offset, determining the path loss of the first signal based on the first path loss offset; and calculating the path loss PL of the first signal using formula (1) b,f,c (q d ):

[0205] Formula (1): PL b,f,c (q d )=referenceSignalPower–higher layer filtered RSRP+PL-offset

[0206] Among them, PL-offset is the first path loss offset, referenceSignalPower is the reference signal power, q d It is the identifier of the reference signal used to determine the path loss, and the higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0207] Step c: When a first path loss offset corresponding to the first signal is determined, the path loss of the first signal is determined based on a path loss reference signal and the first path loss offset.

[0208] In the case where the first information includes information indicating a first path loss offset, the first path loss offset corresponding to the first signal is determined based on the information indicating the first path loss offset corresponding to the first signal; and the path loss of the first signal is calculated using formula (1).

[0209] Step d: If it is determined that the path loss of the first signal is not determined based on the first path loss offset, determine the path loss of the first signal based on a path loss reference signal.

[0210] In the case where the first information includes information indicating that the path loss is not determined based on the first path loss offset, it is determined that the path loss of the first signal is not determined based on the first path loss offset. The path loss PL of the first signal is calculated using formula (2): b,f,c (q d ):

[0211] Formula (2): PL b,f,c (qd )=referenceSignalPower–higher layer filtered RSRP

[0212] Step e: If the path loss of the first signal is not determined based on the first path loss offset, the path loss of the first signal is determined based on a path loss reference signal and a preset path loss offset, where the preset path loss offset is a preset value, such as 0 dB. Optionally, the preset path loss offset is the second path loss offset.

[0213] Use formula (1) to calculate the path loss PL of the first signal b,f,c (q d ):

[0214] Formula (1): PL b,f,c (q d )=referenceSignalPower–higher layer filtered RSRP+PL-offset

[0215] Wherein, PL-offset is a preset path loss offset, and the value of the preset path loss offset is, for example, 0 dB. referenceSignalPower is the reference signal power, q d It is the identifier of the reference signal used to determine the path loss, and the higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0216] Step f: If the first path loss offset corresponding to the first signal is not determined, determine the path loss of the first signal based on the path loss reference signal and the preset path loss offset. For example, use formula (1) to calculate the path loss of the first signal.

[0217] For example, use formula (1) to calculate the path loss PL of the first signal b,f,c (q d ):

[0218] Formula (1): PL b,f,c (q d )=referenceSignalPower–higher layer filtered RSRP+PL-offset

[0219] Where PL-offset is the preset path loss offset. referenceSignalPower is the reference signal power, q d It is the identifier of the reference signal used to determine the path loss, and the higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0220] It should be noted that steps b to f can be performed one by one.

[0221] Optionally, if the first information does not include information indicating a first path loss offset corresponding to the first signal, the path loss of the first signal is determined not based on the first path loss offset. The terminal determines the path loss of the first signal based on a path loss reference signal and a second path loss offset, where the value of the second path loss offset is 0 dB. That is, the path loss of the first signal is determined not based on the first path loss offset corresponding to the first signal, but based on the second path loss offset.

[0222] Optionally, determining the path loss of the first signal based on the path loss reference signal and the first path loss offset includes: determining the path loss of the first signal based on the path loss reference signal and the first path loss offset when a target condition is met, wherein the value of the first path loss offset is a preset value. The preset value is, for example, 0 dB. For example, the path loss of the first signal is calculated using formula (1). The target condition includes: determining that the path loss of the first signal is not determined based on the first path loss offset, or not determining the first path loss offset corresponding to the first signal.

[0223] Optionally, the types of path loss reference signals include synchronization signals / physical broadcast channel blocks and periodically transmitted channel state information reference signals, etc. The path loss reference signal comes from a TRP that can perform downlink transmission, and the path loss reference signal can also be obtained by other means, which will not be described in detail in the embodiments of the present application. In the embodiments of the present disclosure, the path loss reference signal is determined based on at least one of the following: a preset rule; a path loss reference signal corresponding to the first signal indicated by the network side device; a target path loss reference signal indicated by the network side device, wherein the target path loss reference signal is used for uplink transmission corresponding to multiple uplink channels or uplink signals.

[0224] In the path loss determination method provided by the embodiments of the present disclosure, first information is received from a network-side device, the first information including information indicating whether the path loss of a first signal is determined based on a first path loss offset and / or information indicating the first path loss offset. A terminal performs a target operation based on the first information, including determining the path loss of the first signal based on a path loss reference signal and the first path loss offset; or determining the path loss of the first signal based on the path loss reference signal. This allows the terminal to determine, based on the first information, whether the path loss of the first signal is determined based on the first path loss offset, or to determine the first path loss offset corresponding to the first signal. This ensures that the network-side device and the terminal maintain consistent understanding of whether the path loss of uplink transmission is determined based on the path loss offset, thereby ensuring uplink transmission performance.

[0225] Optionally, determining whether to determine the path loss of the first signal based on the first path loss offset, or determining the first path loss offset corresponding to the first signal, based on the first information, includes at least one of the following: if the first information includes information indicating that the path loss is determined based on the first path loss offset, the terminal determines that the path loss of the first signal is determined based on the first path loss offset. If the first information does not include information indicating that the path loss is determined based on the first path loss offset, the terminal determines not to determine the path loss of the first signal based on the first path loss offset. If the first information includes information indicating that the path loss is not determined based on the first path loss offset, the terminal determines not to determine the path loss of the first signal based on the first path loss offset. If the first information includes information indicating that the path loss is not determined based on the first path loss offset, the terminal determines not to determine the path loss of the first signal based on the first path loss offset. If the first information includes information indicating the first path loss offset, the terminal determines the first path loss offset corresponding to the first signal based on the information indicating the first path loss offset corresponding to the first signal.

[0226] Based on the indication content included in the first information, the terminal can determine whether to determine the path loss of the first signal based on the first path loss offset, or determine the first path loss offset corresponding to the first signal, thereby achieving consistent understanding between the network side device and the terminal on whether the path loss of uplink transmission is determined based on the path loss offset.

[0227] Optionally, the terminal determines second information corresponding to the first signal, where the second information includes at least one of a transmission configuration indicator (TCI) state, a sounding reference signal (SRS) resource, and an SRS resource set; and based on the second information, determines the first information, i.e., the first information corresponds to the second information. For example, when the terminal determines the TCI state corresponding to the first signal, the first information is associated information of the TCI state corresponding to the first signal.

[0231] After determining the TCI state corresponding to the first signal, the terminal determines whether the uplink transmission path loss corresponding to the TCI state is determined based on the first path loss offset based on the relationship between the TCI state and the path loss offset. For example, the information indicating the relationship between the TCI state and the path loss offset included in the first information indicates the following: the first TCI state corresponds to determining the path loss of the first signal not based on the first path loss offset, and the second TCI state corresponds to determining the path loss of the first signal based on the first path loss offset.

[0290] Optionally, the spatial related information associated with the first signal includes: information used to configure spatial filtering associated with the first signal.

[0291] Here, the path loss determination method provided by the embodiment of the present disclosure is illustrated through several specific embodiments.

[0292] For the example where the first signal is SRS:

[0293] Solution 1: Determine the SRS resource corresponding to the SRS, where the SRS resource is associated with a TCI state, and the base station configures information in the configuration information of the TCI state that instructs the UE to determine the path loss based on the path loss offset indicated by the base station (which may be an identifier of the path loss offset, or information specifically indicating whether the path loss is determined based on the path loss offset indicated by the base station, or information indicating the path loss offset). The UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station; if the configuration information of the TCI state does not configure information instructing the UE to determine the path loss based on the path loss offset indicated by the base station or information instructing the UE not to determine the path loss based on the path loss offset indicated by the base station, the UE does not determine the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, or determines the path loss corresponding to the SRS transmission based on a path loss offset of 0dB.

[0294] Solution 2: Determine the SRS resource corresponding to the SRS. If the configuration information of the SRS resource is configured with information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station. If the configuration information of the SRS resource is not configured with information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, or is configured with information instructing the UE not to determine the path loss based on the path loss offset indicated by the base station, the UE does not determine the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, or determines the path loss corresponding to the SRS transmission based on a path loss offset of 0 dB.

[0295] Option 1 and Option 2 can be used at the same time. For example:

[0296] Determine the SRS resource corresponding to the SRS. If the SRS resource is associated with a TCI state, and the base station configures information in the configuration information of the TCI state indicating that the UE determines the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station; otherwise, if the configuration information of the SRS resource is configured with information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station; otherwise, the UE does not determine the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, that is, the UE calculates the path loss corresponding to the SRS transmission based on Formula 2, or, when the UE calculates the path loss corresponding to the SRS transmission based on Formula 1, the value of PL-offset is set to 0.

[0297] Solution 3: Determine an SRS resource set corresponding to an SRS, where the SRS resource set is associated with a TCI state, and if the base station configures, in the configuration information of the TCI state, information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station. If the configuration information of the TCI state does not configure information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, or if the configuration information instructs the UE not to determine the path loss based on the path loss offset indicated by the base station, the UE does not determine the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, or determines the path loss corresponding to the SRS transmission based on a path loss offset of 0 dB.

[0298] Solution 4: Determine the SRS resource set corresponding to the SRS. If the configuration information of the SRS resource set is configured with information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station. If the configuration information of the SRS resource set is not configured with information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, or is configured with information instructing the UE not to determine the path loss based on the path loss offset indicated by the base station, the UE does not determine the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, or determines the path loss corresponding to the SRS transmission based on a path loss offset of 0 dB.

[0299] Option 3 and Option 4 can be used in combination. For example:

[0300] Determine the SRS resource set corresponding to the SRS. If the SRS resource set is associated with a TCI state, and the base station configures information in the configuration information of the TCI state indicating that the UE determines the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station; otherwise, if the configuration information of the SRS resource set is configured with information instructing the UE to determine the path loss based on the path loss offset indicated by the base station, the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station; otherwise, the UE does not determine the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, that is, the UE calculates the path loss corresponding to the SRS transmission based on Formula 2, or, when the UE calculates the path loss corresponding to the SRS transmission based on Formula 1, the value of PL-offset is set to 0.

[0301] Solution 5: Determine the SRS resource set corresponding to the SRS, where the SRS resource set includes multiple SRS resources. The base station determines whether the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, or the path loss offset when the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, based on the configuration information associated with the TCI state associated with a specific SRS resource in the SRS resource set (for example, the SRS resource with the smallest number, or the SRS resource with the smallest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the latest ranking).

[0302] Scheme 5-1, the UE determines the path loss corresponding to the SRS transmission based on the information used to indicate the path loss offset in the configuration information of the TCI state associated with the specific SRS resource (that is, information indicating whether the UE determines the path loss based on the path loss offset indicated by the base station, or information indicating the identifier corresponding to the path loss offset, or directly indicating the path loss offset).

[0303] Scheme 5-2, the UE determines the path loss corresponding to the SRS transmission based on the information used to indicate the path loss offset in the configuration information of the specific SRS resource (that is, information indicating whether the UE determines the path loss based on the path loss offset indicated by the base station, or information indicating the identifier corresponding to the path loss offset, or directly indicating the path loss offset).

[0304] Option 5 can be used in conjunction with the previous option.

[0305] Note that in an embodiment of the present invention, the first signal may include multiple layers / multiple transmission opportunities / multiple repetitions / multiple codewords. Optionally, the multiple layers / multiple transmission opportunities / multiple repetitions / multiple codewords of the first signal include multiple groups, each group corresponding to a TCI state / TRP / SRS resource set / CORESETPoolIndex / antenna panel, etc. The method of determining the path loss (for example, a method of determining the path loss based on the path loss offset, or a method of determining the path loss based on the path loss reference signal, or a method of determining the path loss based on a path loss offset of 0dB, or a method of determining the path loss based on the path loss offset indicated by the network device) is different.

[0306] For the example where the first signal is PUSCH:

[0307] Solution 1) Determine the TCI state (one or more) associated with the PUSCH. For each TCI state, for the TCI state for which the TCI state configuration information is configured with information indicating that the UE determines the path loss based on the path loss offset indicated by the base station (which may be an identifier of the path loss offset, or information specifically indicating whether the path loss is determined based on the path loss offset indicated by the base station, or information indicating the path loss offset), the UE determines the path loss corresponding to the PUSCH transmission layer / transmission opportunity / repetition / codeword corresponding to the TCI state based on the path loss offset indicated by the base station (the path loss offset used is the path loss offset corresponding to the TCI state); for the TCI state for which the TCI state configuration information is not configured with information indicating that the UE determines the path loss based on the path loss offset indicated by the base station, or information indicating that the UE does not determine the path loss based on the path loss offset indicated by the base station, the UE does not determine the path loss corresponding to the PUSCH transmission layer / transmission opportunity / repetition / codeword corresponding to the TCI state based on the path loss offset indicated by the base station.

[0308] Solution 2) Determine the SRS resource set associated with the PUSCH. The terminal determines whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal based on the SRS resource set associated with the PUSCH.

[0309] Embodiment 1: The first information includes associated information of the TCI state corresponding to the first signal.

[0310] The terminal determines the TCI state corresponding to the first signal (such as uplink transmission such as PUSCH / PUCCH / SRS / PRACH transmission). Optionally, the TCI state corresponding to the first signal includes the TCI state for determining spatial-related information (for example, transmit beam or spatial filter) and / or quasi-colocation (QCL) information of the first signal. Optionally, the TCI state corresponding to the first signal includes the TCI state for determining spatial-related information (for example, transmit beam or spatial filter) and / or quasi-colocation (QCL) information (optionally, QCL Type-A and / or QCL Type-D) of the SRS resource / SRS resource set / uplink transmission / CORESETPoolIndex / TRP / antenna panel associated with the first signal. The associated information of the TCI state corresponding to the first signal includes information for indicating whether the path loss is determined based on the path loss offset, and / or indicating the path loss offset.

[0311] The terminal determines, based on the association information of the TCI state corresponding to the first signal, whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal;

[0312] The terminal performs a target operation, where the target operation includes determining the path loss of the first signal based on a path loss reference signal and the first path loss offset; or determining the path loss of the first signal based on the path loss reference signal.

[0313] Optionally, the terminal determines, based on the association information of the TCI state corresponding to the first signal, whether to determine the path loss of the first signal based on the first path loss offset, or determines the implementation manner of the first path loss offset corresponding to the first signal, including at least one of the following examples:

[0314] Example 1: The associated information of the TCI state may include a first parameter, and the first parameter is used to indicate the path loss of the first signal determined based on the first path loss offset. For example, the first parameter is named the first path loss offset (pathlossOffset) (of course, it can also be named in other ways). When the associated information of the TCI state includes pathlossOffset, the terminal determines the path loss of the first signal (e.g., PUSCH / PUCCH / SRS / PRACH transmission) associated with the TCI state based on the first path loss offset. When the associated information of the TCI state does not include pathlossOffset, the terminal does not determine the path loss of the first signal (e.g., PUSCH / PUCCH / SRS / PRACH transmission) associated with the TCI state based on the first path loss offset (optionally, it means that the path loss of the first signal associated with the TCI state is determined based on a path loss offset of 0dB).

[0315] Example 2: The associated information of the TCI state may include a second parameter, and the second parameter is used to indicate that the path loss of the first signal is not determined based on the first path loss offset. For example, the second parameter is named the first pathlossOffset. When the associated information of the TCI state does not include pathlossOffset, the path loss corresponding to the first signal associated with the TCI state (for example, PUSCH / PUCCH / SRS / PRACH transmission) is determined based on the first path loss offset. When the associated information of the TCI state includes pathlossOffset, and pathlossOffset is indicated as a specific value (for example, disable), the path loss corresponding to the first signal associated with the TCI state (for example, PUSCH / PUCCH / SRS / PRACH transmission) is not determined based on the first path loss offset (optionally, it means that the path loss of the first signal associated with the TCI state is determined based on a path loss offset of 0dB).

[0316] Example 3: The associated information of the TCI state includes a third parameter, and the third parameter is used to indicate whether the path loss of the first signal is determined based on the first path loss offset. At least part of the value of the third parameter indicates that the path loss of the first signal is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the value of pathlossOffset includes {0,1}. When the value is 0, it indicates that the path loss of the first signal associated with the TCI state is not determined based on the first path loss offset (optionally, it indicates that the path loss of the first signal associated with the TCI state is determined based on a path loss offset of 0dB); when the value is 1, it indicates that the path loss of the first signal associated with the TCI state is determined based on the first path loss offset. Of course, it can also be that when the value is 0, it indicates that the path loss of the first signal associated with the TCI state is determined based on the first path loss offset; when the value is 0, it indicates that the path loss of the first signal associated with the TCI state is not determined based on the first path loss offset (optionally, it indicates that the path loss of the first signal associated with the TCI state is determined based on a path loss offset of 0dB).

[0317] Example 4: The associated information of the TCI state includes a fourth parameter, which is used to indicate that the path loss of the first signal is not determined based on the first path loss offset; or, the fourth parameter is used to indicate that the path loss of the first signal is determined based on the first path loss offset, and also indicates identification information of the first path loss offset, and the identification information of the first path loss offset is used to determine the first path loss offset. At least some values ​​of the fourth parameter indicate that the path loss of the first signal is determined based on the first path loss offset, and also indicate identification information of the first path loss offset. The UE determines the first path loss offset used to determine the path loss of the first signal based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it means that the path loss of the first signal associated with the TCI state is not determined based on the first path loss offset (optionally, it means that the path loss of the first signal associated with the TCI state is determined based on a path loss offset of 0dB); when the value is 1, it means that the path loss of the first signal associated with the TCI state is determined based on the first path loss offset; when the value is 2, it means that the path loss of the first signal associated with the TCI state is determined based on the third path loss offset.

[0318] In the above example, the first path loss offset and the third path loss offset are both indicated to the UE by a network-side device, such as a base station.

[0319] Optionally, the TCI state-associated information is TCI state configuration information, and the TCI state configuration information is used to configure the TCI state. For example, the TCI state-associated information is TCI-State or TCI uplink state (TCI-UL-State) in RRC signaling.

[0320] Optionally, the TCI state associated information is information for configuring power control parameters associated with the TCI state. For example, the TCI state associated information is uplink power control (ul-powerControl) information included in the TCI state configuration information.

[0321] Embodiment 2: The first information includes configuration information of SRS resources corresponding to the first signal.

[0322] The terminal determines an SRS resource corresponding to a first signal (such as an uplink transmission such as PUSCH / PUCCH / SRS / PRACH transmission). The SRS resource corresponding to the first signal is the SRS resource configured or indicated by the base station for the uplink transmission.

[0323] For example, the base station configures SRS resources for PUSCH / PUCCH / SRS / PRACH transmission through RRC signaling, or the base station indicates SRS resources for PUSCH / PUCCH / SRS / PRACH transmission through MAC-CE signaling or DCI signaling.

[0324] Taking PUSCH transmission as an example, an example of an SRS resource corresponding to a PUSCH transmission is that the SRS resource is an SRS resource used to determine the precoding of the PUSCH. For example, the base station indicates the SRS resource for the PUSCH transmission through an SRS resource indicator (SRI).

[0325] Taking SRS transmission as an example, an example of an SRS resource corresponding to an SRS transmission is: the SRS resource is an SRS resource used to determine information such as resources corresponding to the SRS transmission.

[0326] Optionally, the SRS resources corresponding to the uplink transmission (e.g., PUSCH / PUCCH / SRS / PRACH transmission) are SRS resources used to determine the TRP and / or transmit beam and / or precoding corresponding to the PUSCH / PUCCH / SRS / PRACH transmission.

[0327] Optionally, the configuration information of the SRS resource corresponding to the first signal includes information indicating whether to determine the path loss based on the path loss offset and / or indicating the path loss offset.

[0328] The terminal determines, based on the configuration information of the SRS resource corresponding to the first signal, whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal.

[0329] The terminal performs a target operation, where the target operation includes: determining the path loss of the first signal based on a path loss reference signal and the first path loss offset; or determining the path loss of the first signal based on the path loss reference signal.

[0330] Optionally, the terminal determines, based on the configuration information of the SRS resource corresponding to the first signal, whether to determine the path loss of the first signal based on the first path loss offset, or determines an implementation manner of the first path loss offset corresponding to the first signal, including at least one of the following examples:

[0331] Example 1: The configuration information of the SRS resource may include a first parameter, which is used to indicate the path loss of the first signal determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the configuration information of the SRS resource includes pathlossOffset, the terminal determines the path loss of the first signal associated with the SRS resource (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset. When the configuration information of the SRS resource does not include pathlossOffset, the terminal does not determine the path loss of the first signal associated with the SRS resource based on the first path loss offset (optionally, the path loss of the first signal associated with the SRS resource is determined based on a path loss offset of 0dB).

[0332] Example 2: The configuration information of the SRS resource may include a second parameter, and the second parameter is used to indicate that the path loss of the first signal is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset. When pathlossOffset is not included in the configuration information of the SRS resource, the path loss of the first signal associated with the SRS resource is determined based on the first path loss offset. When pathlossOffset is included in the configuration information of the SRS resource and is indicated as a specific value (for example, disable), the path loss of the first signal associated with the SRS resource is not determined based on the first path loss offset (optionally, the path loss of the first signal associated with the SRS resource is determined based on a path loss offset of 0dB).

[0333] Example 3: The configuration information of the SRS resource includes a third parameter, and the third parameter is used to indicate whether the path loss of the first signal is determined based on the first path loss offset. At least part of the value of the third parameter indicates that the path loss of the first signal is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the value of pathlossOffset includes {0,1}. When the value is 0, it indicates that the path loss of the first signal associated with the SRS resource is not determined based on the first path loss offset (optionally, it indicates that the path loss of the first signal associated with the SRS resource is determined based on a path loss offset of 0dB); when the value is 1, it indicates that the path loss of the first signal associated with the SRS resource is determined based on the first path loss offset.

[0334] Example 4: The configuration information for the SRS resource includes a fourth parameter, which is used to indicate that the path loss of the first signal is not determined based on the first path loss offset; or, the fourth parameter is used to indicate that the path loss of the first signal is determined based on the first path loss offset, and simultaneously indicates identification information of the first path loss offset, where the identification information of the first path loss offset is used to determine the first path loss offset. At least some values ​​of the fourth parameter indicate that the path loss of the first signal is determined based on the first path loss offset, and simultaneously indicate identification information of the first path loss offset. The UE determines the first path loss offset used to determine the path loss of the first signal based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it means that the path loss of the first signal associated with the SRS resource is not determined based on the first path loss offset (optionally, the path loss of the first signal associated with the SRS resource is determined based on a path loss offset of 0dB); when the value is 1, it means that the path loss of the first signal associated with the SRS resource is determined based on the first path loss offset; when the value is 2, it means that the path loss of the first signal associated with the SRS resource is determined based on the third path loss offset.

[0335] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE. The signaling used by the base station to indicate the first path loss offset and the third path loss offset to the UE can be the signaling used to indicate the first information, or other signaling.

[0336] Optionally, the configuration information of the SRS resource is information used to configure the SRS resource. For example, the configuration information of the SRS resource is RRC signaling SRS-Resource.

[0337] Optionally, the configuration information of the SRS resource is information for configuring power control parameters associated with the SRS resource. For example, the configuration information of the SRS resource is MAC-CE signaling for configuring power control parameters associated with the SRS resource.

[0338] Embodiment 3: The first information includes configuration information of an SRS resource set corresponding to the first signal.

[0339] The terminal determines an SRS resource set corresponding to a first signal (e.g., a PUSCH / PUCCH / SRS / PRACH transmission). Based on configuration information of the SRS resource set corresponding to the first signal, the terminal determines whether to determine a path loss of the first signal based on a first path loss offset, or determines the first path loss offset corresponding to the first signal. The terminal performs a target operation, the target operation including: determining the path loss of the first signal based on a path loss reference signal and the first path loss offset; or determining the path loss of the first signal based on the path loss reference signal.

[0340] Optionally, the terminal determines, based on the configuration information of the SRS resource set corresponding to the first signal, whether to determine the path loss of the first signal based on the first path loss offset, or determines an implementation manner of the first path loss offset corresponding to the first signal, including at least one of the following examples:

[0341] Example 1: The configuration information of the SRS resource set includes a first parameter, which is used to indicate the path loss of the first signal determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the configuration information of the SRS resource set includes pathlossOffset, the terminal determines the path loss of the first signal associated with the SRS resource set based on the first path loss offset. When the configuration information of the SRS resource set does not include pathlossOffset, the terminal does not determine the path loss of the first signal associated with the SRS resource set based on the first path loss offset (optionally, the path loss of the first signal associated with the SRS resource set is determined based on a path loss offset of 0dB).

[0342] Example 2: The configuration information of the SRS resource set may include a second parameter, and the second parameter is used to indicate that the path loss of the first signal is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset, and when pathlossOffset is not included in the configuration information of the SRS resource set, the path loss of the first signal associated with the SRS resource set is determined based on the first path loss offset. When pathlossOffset is included in the configuration information of the SRS resource set and is indicated as a specific value (for example, disable), the path loss of the first signal associated with the SRS resource set is not determined based on the first path loss offset (optionally, the path loss of the first signal associated with the SRS resource set is determined based on a path loss offset of 0dB).

[0343] Example 3: The configuration information of the SRS resource set includes a third parameter, and the third parameter is used to indicate whether the first signal path loss is determined based on the first path loss offset. At least part of the value of the third parameter indicates that the first signal path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the value of pathlossOffset includes {0,1}. When the value is 0, it indicates that the first signal path loss associated with the SRS resource set is not determined based on the first path loss offset (optionally, it indicates that the path loss of the first signal associated with the SRS resource set is determined based on a path loss offset of 0dB); when the value is 1, it indicates that the first signal path loss associated with the SRS resource set is determined based on the first path loss offset.

[0344] Example 4: The configuration information of the SRS resource set includes a fourth parameter, which is used to indicate that the path loss of the first signal is not determined based on the first path loss offset; or, the fourth parameter is used to indicate that the path loss of the first signal is determined based on the first path loss offset, and also indicates identification information of the first path loss offset, and the identification information of the first path loss offset is used to determine the first path loss offset. At least some values ​​of the fourth parameter indicate that the path loss of the first signal is determined based on the first path loss offset, and also indicate identification information of the first path loss offset. The UE determines the first path loss offset used to determine the path loss of the first signal based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it means that the path loss of the first signal associated with the SRS resource set is not determined based on the first path loss offset (optionally, it means that the path loss of the first signal associated with the SRS resource set is determined based on a path loss offset of 0dB); when the value is 1, it means that the path loss of the first signal associated with the SRS resource set is determined based on the first path loss offset; when the value is 2, it means that the path loss of the first signal associated with the SRS resource set is determined based on the third path loss offset.

[0345] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE.

[0348] Embodiment 4: Determine an SRS resource set corresponding to an SRS, where the SRS resource set includes multiple SRS resources. The base station determines whether the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, or the path loss offset when the UE determines the path loss corresponding to the SRS transmission based on the path loss offset indicated by the base station, based on the configuration information associated with the TCI state associated with a specific SRS resource in the SRS resource set (for example, the SRS resource with the smallest number, or the SRS resource with the smallest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the last order).

[0349] The UE determines the path loss corresponding to the SRS transmission based on the information used to indicate the path loss offset in the configuration information of the TCI state associated with the specific SRS resource (i.e., information indicating whether the UE determines the path loss based on the path loss offset indicated by the base station, or information indicating the identifier corresponding to the path loss offset, or directly indicating the path loss offset).

[0350] Alternatively, the UE determines the path loss corresponding to the SRS transmission based on the information used to indicate the path loss offset in the configuration information of the specific SRS resource (i.e., information indicating whether the UE determines the path loss based on the path loss offset indicated by the base station, or information indicating the identifier corresponding to the path loss offset, or directly indicating the path loss offset).

[0351] Embodiment 5: The first information includes space-related information associated with SRS transmission corresponding to the first signal.

The spatial related information associated with the SRS transmission corresponding to the first signal includes information indicating whether to determine the path loss based on the path loss offset and / or indicating the path loss offset.

[0353] The terminal determines, based on the spatial related information associated with the SRS transmission corresponding to the first signal, whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal.

[0356] Example 1: The spatial related information associated with the SRS transmission includes a first parameter, and the first parameter is used to indicate the path loss of the first signal determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the spatial related information associated with the SRS transmission includes pathlossOffset, the terminal determines the path loss of the first signal associated with the spatial related information based on the first path loss offset. When the spatial related information associated with the SRS transmission does not include pathlossOffset, the terminal does not determine the path loss of the first signal associated with the spatial related information based on the first path loss offset (optionally, the path loss of the first signal associated with the spatial related information is determined based on a path loss offset of 0dB).

[0357] Example 2: The spatial related information associated with the SRS transmission may include a second parameter, and the second parameter is used to indicate that the path loss of the first signal is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset, and when the spatial related information associated with the SRS transmission does not include pathlossOffset, the path loss of the first signal associated with the spatial related information is determined based on the first path loss offset. When pathlossOffset is included in the spatial related information associated with the SRS transmission and is indicated as a specific value (for example, disable), the path loss of the first signal associated with the spatial related information is not determined based on the first path loss offset (optionally, the path loss of the first signal associated with the spatial related information is determined based on a path loss offset of 0dB).

[0358] Example 3: The spatial related information associated with the SRS transmission includes a third parameter, and the third parameter is used to indicate whether the path loss of the first signal is determined based on the first path loss offset. At least part of the value of the third parameter indicates that the path loss of the first signal is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the value of pathlossOffset includes {0,1}. When the value is 0, it indicates that the path loss of the first signal associated with the spatial related information is not determined based on the first path loss offset (optionally, it indicates that the path loss of the first signal associated with the spatial related information is determined based on a path loss offset of 0dB); when the value is 1, it indicates that the path loss of the first signal associated with the spatial related information is determined based on the first path loss offset.

[0359] Example 4: The spatial related information associated with the SRS transmission includes a fourth parameter, and the fourth parameter is used to indicate that the path loss of the first signal is not determined based on the first path loss offset (optionally, it is used to indicate that the path loss of the first signal associated with the spatial related information is determined based on a path loss offset of 0dB); or, the fourth parameter is used to indicate that the path loss of the first signal is determined based on the first path loss offset, and at the same time indicates the identification information of the first path loss offset, and the identification information of the first path loss offset is used to determine the first path loss offset. At least part of the value of the fourth parameter indicates that the path loss of the first signal is determined based on the first path loss offset, and at the same time indicates the identification information of the first path loss offset. The UE determines the first path loss offset used to determine the path loss of the first signal based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it means that the path loss of the first signal associated with the spatial related information is not determined based on the first path loss offset (optionally, it means that the path loss of the first signal associated with the spatial related information is determined based on a path loss offset of 0dB); when the value is 1, it means that the path loss of the first signal associated with the spatial related information is determined based on the first path loss offset; when the value is 2, it means that the path loss of the first signal associated with the spatial related information is determined based on the third path loss offset.

[0360] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE.

[0361] Optionally, the spatially relevant information is information used to configure spatial filtering. For example, spatially relevant information associated with SRS transmission, such as RRC signaling spatialRelationInfo. Spatially relevant information associated with PUSCH transmission, such as SRI information. For PUCCH transmission, spatially relevant information associated with PUCCH transmission is used to determine whether to determine the PUCCH path loss based on the first path loss offset.

[0362] Embodiment 6: The first information includes configuration information of the first signal.

[0363] The first signal may include at least one of the following: PUSCH, PUCCH, SRS, and PRACH. The first signal is described as PUSCH as an example.

[0364] The terminal determines PUSCH configuration information, and determines, based on the PUSCH configuration information, whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal;

[0365] The terminal performs a target operation, where the target operation includes determining the path loss of the first signal based on a path loss reference signal and the first path loss offset; or determining the path loss of the first signal based on the path loss reference signal.

[0366] Optionally, the terminal determines, based on the PUSCH configuration information, whether to determine the path loss of the first signal based on the first path loss offset, or determines an implementation manner of the first path loss offset corresponding to the first signal, including at least one of the following examples:

[0367] Example 1: The configuration information of the PUSCH may include a first parameter, and the first parameter is used to indicate the path loss of the PUSCH determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the configuration information of the PUSCH includes pathlossOffset, the terminal determines the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset. When the configuration information of the PUSCH does not include pathlossOffset, the terminal does not determine the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset (optionally, the path loss of the first signal of the uplink transmission associated with the PUSCH is determined based on a path loss offset of 0dB).

[0368] Example 2: The configuration information of the PUSCH may include a second parameter, and the second parameter is used to indicate that the path loss of the PUSCH is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset. When pathlossOffset is not included in the configuration information of the PUSCH, the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is determined based on the first path loss offset. When pathlossOffset is included in the configuration information of the PUSCH and is indicated as a specific value (e.g., disable), the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is not determined based on the first path loss offset (optionally, the path loss of the first signal of the uplink transmission associated with the PUSCH is determined based on a path loss offset of 0dB).

[0369] Example 3: The configuration information of PUSCH includes a third parameter, and the third parameter is used to indicate whether the path loss of PUSCH is determined based on the first path loss offset. At least part of the value of the third parameter indicates that the path loss of PUSCH is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the value of pathlossOffset includes {0,1}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the PUSCH is not determined based on the first path loss offset (optionally, the path loss of the first signal of the uplink transmission associated with the PUSCH is determined based on the path loss offset of 0dB); when the value is 1, it indicates that the path loss of the uplink transmission associated with the PUSCH is determined based on the first path loss offset.

[0370] Example 4: The PUSCH configuration information includes a fourth parameter, which is used to indicate that the PUSCH path loss is not determined based on the first path loss offset; or, the fourth parameter is used to indicate that the PUSCH path loss is determined based on the first path loss offset, and also indicates identification information of the first path loss offset, where the identification information of the first path loss offset is used to determine the first path loss offset. At least some values ​​of the fourth parameter indicate that the path loss is determined based on the first path loss offset, and also indicate identification information of the first path loss offset. The UE determines the first path loss offset for determining the path loss based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the PUSCH is not determined based on the first path loss offset (optionally, the path loss of the first signal of the uplink transmission associated with the PUSCH is determined based on the path loss offset of 0dB); when the value is 1, it indicates that the path loss of the uplink transmission associated with the PUSCH is determined based on the first path loss offset; when the value is 2, it indicates that the path loss of the uplink transmission associated with the PUSCH is determined based on the third path loss offset.

[0371] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE. The signaling used to indicate the first path loss offset and / or the third path loss offset is the same as or different from the first information.

[0372] As some other examples, a method for determining, through PUSCH configuration information, whether the path loss corresponding to PUSCH transmission is determined based on the first path loss offset includes:

[0373] Example 1: Information indicating the relationship between the TCI state and the path loss offset is included in the PUSCH configuration information. Based on the relationship, it is determined whether the path loss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to each TCI state in the PUSCH transmission is determined based on the first path loss offset. For example, the information indicating the relationship between the TCI state and the path loss offset included in the PUSCH configuration information indicates the following information: the first TCI state corresponds to the path loss corresponding to the PUSCH transmission opportunity / layer / repetition to which it corresponds is not determined based on the first path loss offset, and the second TCI state corresponds to the path loss corresponding to the PUSCH transmission opportunity / layer / repetition to which it corresponds is determined based on the first path loss offset. Then, the UE does not determine the path loss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to the first TCI state based on the first path loss offset (optionally, the path loss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to the first TCI state is determined based on a path loss offset of 0dB), and determines the path loss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to the second TCI state based on the first path loss offset.

[0374] For example, when the first information includes PUSCH configuration information, and the PUSCH configuration information includes a relationship between the TCI state and the path loss offset, the terminal determines whether to determine the path loss corresponding to the uplink transmission based on the first path loss offset according to the relationship between the TCI state and the path loss offset;

[0375] In the case of determining the path loss corresponding to the uplink transmission based on the first path loss offset, the target operation performed by the terminal according to the first information is: determining the path loss based on the path loss reference signal corresponding to the uplink transmission and the first path loss offset.

[0376] In the case where it is determined not to determine the path loss corresponding to the uplink transmission based on the first path loss offset, the target operation performed by the terminal according to the first information is: determining the path loss based on the path loss reference signal corresponding to the uplink transmission.

[0377] Example 2: The PUSCH configuration information includes information indicating the relationship between the SRS resource set and the pathloss offset. Based on the relationship, it is determined whether the pathloss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to each SRS resource set in the PUSCH transmission is determined based on the first pathloss offset.

[0378] For example, when the first information includes PUSCH configuration information, and the PUSCH configuration information includes a relationship between an SRS resource set and a path loss offset, the terminal determines, based on the relationship between the SRS resource set and the path loss offset, whether to determine the path loss corresponding to the uplink transmission based on the first path loss offset. If it is determined that the path loss corresponding to the uplink transmission is to be determined based on the first path loss offset, the terminal performs a target operation based on the first information: determining the path loss based on a path loss reference signal corresponding to the uplink transmission and the first path loss offset. If it is determined that the path loss corresponding to the uplink transmission is not to be determined based on the first path loss offset, the terminal performs a target operation based on the first information: determining the path loss based on the path loss reference signal corresponding to the uplink transmission.

[0379] Example 3: The PUSCH configuration information includes information indicating the relationship between coresetPoolIndex and the pathloss offset. Based on the relationship, it is determined whether the pathloss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to each coresetPoolIndex in PUSCH transmission is determined based on the first pathloss offset.

[0380] For example, when the first information includes PUSCH configuration information, and the PUSCH configuration information includes a relationship between coresetPoolIndex and a path loss offset, the terminal determines, based on the relationship between coresetPoolIndex and the path loss offset, whether to determine the path loss corresponding to the uplink transmission based on the first path loss offset. If the path loss corresponding to the uplink transmission is determined based on the first path loss offset, the terminal performs a target operation based on the first information: determining the path loss based on a path loss reference signal corresponding to the uplink transmission and the first path loss offset. If the path loss corresponding to the uplink transmission is determined not to be determined based on the first path loss offset, the terminal performs a target operation based on the first information: determining the path loss based on the path loss reference signal corresponding to the uplink transmission.

[0381] Example 4: The PUSCH configuration information includes information indicating a relationship between a power control parameter set and a path loss offset. Based on the relationship, it is determined whether the path loss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to each power control parameter set in the PUSCH transmission is determined based on the first path loss offset.

[0382] For example, when the first information includes PUSCH configuration information, and the PUSCH configuration information includes a relationship between a power control parameter set and a path loss offset, the terminal determines, based on the relationship between the power control parameter set and the path loss offset, whether to determine the path loss corresponding to the uplink transmission based on the first path loss offset. If it is determined that the path loss corresponding to the uplink transmission is to be determined based on the first path loss offset, the terminal performs a target operation based on the first information: determining the path loss based on a path loss reference signal corresponding to the uplink transmission and the first path loss offset. If it is determined that the path loss corresponding to the uplink transmission is not to be determined based on the first path loss offset, the terminal performs a target operation based on the first information: determining the path loss based on the path loss reference signal corresponding to the uplink transmission.

[0383] As an example, the PUSCH configuration information is transmission parameter information used to configure the PUSCH, such as RRC signaling pusch-Config.

[0384] As another example, the PUSCH configuration information is power control parameter information used to configure the PUSCH.

[0385] Embodiment 7: The first information includes SRS resource set indication information used for first signal transmission.

[0386] The first signal may include at least one of the following: PUSCH, PUCCH, SRS, and PRACH. The first signal is described as PUSCH as an example.

[0387] The terminal determines SRS resource set indication information for PUSCH transmission; based on the SRS resource set indication information, the terminal determines whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal.

[0388] Optionally, the terminal determines, based on the SRS resource set indication information, whether to determine the path loss of the first signal based on the first path loss offset, or determines an implementation manner of the first path loss offset corresponding to the first signal, including at least one of the following examples:

[0389] Example 1: The SRS resource set indication information may include a first parameter, which is used to indicate the path loss of the PUSCH determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the SRS resource set indication information includes pathlossOffset, the terminal determines the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset. When the SRS resource set indication information does not include pathlossOffset, the terminal does not determine the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset.

[0390] Example 2: The SRS resource set indication information may include a second parameter, and the second parameter is used to indicate that the path loss of the PUSCH is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset. When the SRS resource set indication information does not include pathlossOffset, the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is determined based on the first path loss offset. When the SRS resource set indication information includes pathlossOffset and is indicated as a specific value (e.g., disable), the path loss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is not determined based on the first path loss offset.

[0391] Example 3: The SRS resource set indication information includes a third parameter, which is used to indicate whether the path loss of the PUSCH is determined based on the first path loss offset. At least some of the values ​​of the third parameter indicate that the path loss of the PUSCH is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0,1}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the PUSCH is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the PUSCH is determined based on the first path loss offset.

[0392] Example 4: The SRS resource set indication information includes a fourth parameter, which is used to indicate that the PUSCH pathloss is not determined based on the first pathloss offset; or, the fourth parameter is used to indicate that the PUSCH pathloss is determined based on the first pathloss offset and also indicates identification information of the first pathloss offset, where the identification information of the first pathloss offset is used to determine the first pathloss offset. At least some values ​​of the fourth parameter indicate that the PUSCH pathloss is determined based on the first pathloss offset and also indicate identification information of the first pathloss offset. The UE determines the first pathloss offset used to determine the pathloss based on the identification information of the first pathloss offset. For example, the fourth parameter is named pathlossOffset, and its values ​​include {0, 1, 2}. When the value is 0, the pathloss of the uplink transmission associated with the PUSCH is not determined based on the first pathloss offset; when the value is 1, the pathloss of the uplink transmission associated with the PUSCH is determined based on the first pathloss offset; and when the value is 2, the pathloss of the uplink transmission associated with the PUSCH is determined based on the third pathloss offset.

[0393] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE.

[0394] As some other examples, some methods for determining whether the path loss corresponding to PUSCH transmission is determined based on the first path loss offset through SRS resource set indication information include:

[0395] Example 1: Determine the relationship between the SRS resource set indication information and the path loss offset. Based on the relationship, determine whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset.

[0396] For example, when the value of the SRS resource set indication information is a specific value (eg, 00 or 01), the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset.

[0397] Optionally, the relationship between the SRS resource set indication information and the path loss offset is indicated by the base station to the UE, or is agreed upon by a protocol.

[0398] Example 2: Determine the relationship between the SRS resource set and the path loss offset; determine whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset based on the SRS resource set indication information and the relationship. The SRS resource set is an SRS resource set that can be indicated by the SRS resource set indication information. Optionally, when the PUSCH transmission is a codebook-based PUSCH transmission (for example, txConfig is configured as codebook), the SRS resource set is an SRS resource set whose usage is codebook. Optionally, when the PUSCH transmission is a non-codebook PUSCH transmission (for example, txConfig is configured as nonCodebook), the SRS resource set is an SRS resource set whose usage is nonCodebook.

[0399] For example, the relationship between the SRS resource set and the path loss offset is as follows: the first SRS resource set corresponds to a path loss corresponding to its corresponding PUSCH transmission that is not determined based on the first path loss offset, and the second SRS resource set corresponds to a path loss corresponding to its corresponding PUSCH transmission that is determined based on the first path loss offset. Therefore, when the SRS resource set indication information only indicates the first SRS resource set, the path loss corresponding to the PUSCH transmission is not determined based on the first path loss offset; when the SRS resource set indication information only indicates the second SRS resource set, the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset; when the SRS resource set indication information indicates both the first and second SRS resource sets, the path loss corresponding to the transmission timing / layer / repetition of the PUSCH transmission corresponding to the first SRS resource set is not determined based on the first path loss offset, and the path loss corresponding to the transmission timing / layer / repetition of the PUSCH transmission corresponding to the second SRS resource set is determined based on the first path loss offset.

[0400] Optionally, an example of the relationship between the SRS resource set and the path loss offset is:

[0401] For example, the first SRS resource set corresponds to the path loss corresponding to the PUSCH transmission determined based on the first path loss offset, and the second SRS resource set corresponds to the path loss corresponding to the PUSCH transmission determined based on the first path loss offset;

[0402] For example, the first SRS resource set corresponds to a path loss corresponding to a PUSCH transmission determined based on a first path loss offset, and the second SRS resource set corresponds to a path loss corresponding to a PUSCH transmission not determined based on the first path loss offset.

[0403] Optionally, for Example 2, the relationship between the SRS resource set and the path loss offset is indicated by the base station to the UE, or is agreed upon by a protocol.

[0404] Example 3: Determine the relationship between the TCI state and the path loss offset and the relationship between the SRS resource set indication information and the TCI state; and determine, based on the relationship, whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset.

[0405] For example, the relationship between the TCI state and the path loss offset is as follows: the first TCI state corresponds to a path loss corresponding to the PUSCH transmission that is not determined based on the first path loss offset, and the second TCI state corresponds to a path loss corresponding to the PUSCH transmission that is determined based on the first path loss offset. Therefore, when the SRS resource set indication information indicates the first TCI state, the path loss corresponding to the PUSCH transmission is not determined based on the first path loss offset; when the SRS resource set indication information indicates only the second TCI state, the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset; when the SRS resource set indication information indicates both the first and second TCI states, the path loss corresponding to the transmission timing / layer / repetition of the PUSCH transmission corresponding to the first TCI state is not determined based on the first path loss offset, and the path loss corresponding to the transmission timing / layer / repetition of the PUSCH transmission corresponding to the second TCI state is determined based on the first path loss offset.

[0406] Optionally, an example of the relationship between the TCI state and the path loss offset is:

[0407] For example, the first TCI state corresponds to the path loss corresponding to the PUSCH transmission determined based on the first path loss offset, and the second TCI state corresponds to the path loss corresponding to the PUSCH transmission determined based on the first path loss offset.

[0408] For example, the first TCI state corresponds to determining the path loss corresponding to the PUSCH transmission based on the first path loss offset, and the second TCI state corresponds to determining the path loss corresponding to the PUSCH transmission not based on the first path loss offset.

[0409] Optionally, the relationship between the TCI state and the path loss offset is indicated by the base station to the UE, or is agreed upon by a protocol.

[0410] Optionally, the relationship between the SRS resource set indication information and the TCI state is indicated by the base station to the UE, or is agreed upon by a protocol.

[0411] Example 4: Determine the relationship between the power control parameter and the path loss offset and the relationship between the SRS resource set indication information and the power control parameter; and determine whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset based on the relationship.

[0412] Embodiment 8: The first information includes space-related information associated with the first signal.

[0413] The first signal may include at least one of the following: PUSCH, PUCCH, SRS, and PRACH. The first signal is described as PUSCH as an example.

[0414] The terminal determines the spatial related information associated with the PUSCH transmission; based on the spatial related information associated with the PUSCH transmission, the terminal determines whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal.

[0415] Optionally, the terminal determines, based on the spatial related information associated with the PUSCH transmission, whether to determine the path loss of the first signal based on the first path loss offset, or determines the first path loss offset corresponding to the first signal, where the first path loss offset is an implementation manner of the path loss offset indicated by the network side device, including at least one of the following examples:

[0416] Example 1: The spatial related information associated with the PUSCH transmission includes a first parameter, and the first parameter is used to indicate that the path loss is determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the spatial related information associated with the PUSCH transmission includes pathlossOffset, the terminal determines the path loss corresponding to the uplink transmission associated with the spatial related information (e.g., PUSCH transmission) based on the first path loss offset. When the spatial related information associated with the PUSCH transmission does not include pathlossOffset, the terminal does not determine the path loss corresponding to the uplink transmission associated with the spatial related information (e.g., PUSCH transmission) based on the first path loss offset.

[0417] Example 2: The spatial related information associated with the PUSCH transmission may include a second parameter, and the second parameter is used to indicate that the path loss is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset, and when the spatial related information associated with the PUSCH transmission does not include pathlossOffset, the path loss corresponding to the uplink transmission (e.g., PUSCH transmission) of the associated spatial related information is determined based on the first path loss offset. When the spatial related information associated with the PUSCH transmission includes pathlossOffset and is indicated as a specific value (e.g., disable), the path loss corresponding to the uplink transmission (e.g., PUSCH transmission) of the associated spatial related information is not determined based on the first path loss offset.

[0418] Example 3: The spatial related information associated with the PUSCH transmission includes a third parameter, and the third parameter is used to indicate whether the path loss is determined based on the first path loss offset. At least some of the values ​​of the third parameter indicate that the path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0,1}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the spatial related information is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the spatial related information is determined based on the first path loss offset.

[0419] Example 4: The spatially relevant information associated with PUSCH transmission includes a fourth parameter, the fourth parameter being used to indicate that path loss is not determined based on the first path loss offset; or the fourth parameter being used to indicate that path loss is determined based on the first path loss offset and simultaneously indicating identification information of the first path loss offset, the identification information of the first path loss offset being used to determine the first path loss offset. At least some values ​​of the fourth parameter indicate that path loss is determined based on the first path loss offset and simultaneously indicate identification information of the first path loss offset. The UE determines the first path loss offset used to determine path loss based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset, and the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the spatially relevant information is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the spatially relevant information is determined based on the first path loss offset; and when the value is 2, it indicates that the path loss of the uplink transmission associated with the spatially relevant information is determined based on a third path loss offset.

[0420] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE.

[0421] Embodiment 9: The first information includes configuration information of PUCCH resources.

[0422] The first signal may include at least one of the following: PUSCH, PUCCH, SRS, and PRACH. The first signal is described as PUCCH as an example.

[0423] The terminal determines configuration information of the PUCCH resource, and based on the configuration information of the PUCCH resource, determines whether to determine the path loss of the PUCCH based on the first path loss offset, or determines the first path loss offset corresponding to the PUCCH.

[0424] Optionally, the terminal determines, based on the configuration information of the PUCCH resource, whether to determine the path loss of the PUCCH based on the first path loss offset, or determines the first path loss offset corresponding to the PUCCH, where the first path loss offset is an implementation method of the path loss offset indicated by the network side device, including at least one of the following examples:

[0425] Example 1: The configuration information of the PUCCH resource may include a first parameter, and the first parameter is used to indicate that the path loss is determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the configuration information of the PUCCH resource includes pathlossOffset, the terminal determines the path loss corresponding to the uplink transmission associated with the PUCCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset. When the configuration information of the PUCCH resource does not include pathlossOffset, the terminal does not determine the path loss corresponding to the uplink transmission associated with the PUCCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset.

[0426] Example 2: The configuration information of the PUCCH resource may include a second parameter, and the second parameter is used to indicate that the path loss is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset. When pathlossOffset is not included in the configuration information of the PUCCH resource, the path loss corresponding to the uplink transmission associated with the PUCCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is determined based on the first path loss offset. When pathlossOffset is included in the configuration information of the PUCCH resource and is indicated as a specific value (e.g., disable), the path loss corresponding to the uplink transmission associated with the PUCCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is not determined based on the first path loss offset.

[0427] Example 3: The configuration information of the PUCCH resource includes a third parameter, and the third parameter is used to indicate whether the path loss is determined based on the first path loss offset. At least some values ​​of the third parameter indicate that the path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0,1}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the PUCCH is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the PUCCH is determined based on the first path loss offset.

[0428] Example 4: The configuration information of the PUCCH resource includes a fourth parameter, and the fourth parameter is used to indicate that the path loss is not determined based on the first path loss offset; or, the fourth parameter is used to indicate that the path loss is determined based on the first path loss offset, and at the same time indicates the identification information of the first path loss offset, and the identification information of the first path loss offset is used to determine the first path loss offset. At least part of the value of the fourth parameter indicates that the path loss is determined based on the first path loss offset, and at the same time indicates the identification information of the first path loss offset. The UE determines the first path loss offset used to determine the path loss based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset, and for example, the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the PUCCH is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the PUCCH is determined based on the first path loss offset; when the value is 2, it indicates that the path loss of the uplink transmission associated with the PUCCH is determined based on the third path loss offset.

[0429] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE.

[0430] Embodiment 10: The first information includes information for indicating space-related information associated with PUCCH resources.

[0431] The first signal may include at least one of the following: PUSCH, PUCCH, SRS, and PRACH. The first signal is described as PUCCH as an example.

[0432] The terminal determines the spatial related information associated with the PUCCH transmission; based on the spatial related information associated with the PUCCH transmission, the terminal determines whether to determine the path loss of the PUCCH based on the first path loss offset, or determines the first path loss offset corresponding to the PUCCH.

[0433] Optionally, the terminal determines, based on the spatial related information associated with the PUCCH transmission, whether to determine the path loss of the PUCCH based on the first path loss offset, or determines the first path loss offset corresponding to the PUCCH, where the first path loss offset is an implementation method of the path loss offset indicated by the network side device, including at least one of the following examples:

[0434] Example 1: The spatial related information associated with the PUCCH transmission includes a first parameter, and the first parameter is used to indicate that the path loss is determined based on the first path loss offset. For example, the first parameter is named pathlossOffset. When the spatial related information associated with the PUCCH transmission includes pathlossOffset, the terminal determines the path loss corresponding to the uplink transmission (e.g., PUCCH transmission) associated with the spatial related information based on the first path loss offset. When the spatial related information associated with the PUCCH transmission does not include pathlossOffset, the terminal does not determine the path loss corresponding to the uplink transmission (e.g., PUCCH transmission) associated with the spatial related information based on the first path loss offset.

[0435] Example 2: The spatial related information associated with the PUCCH transmission may include a second parameter, and the second parameter is used to indicate that the path loss is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset, and when the spatial related information associated with the PUCCH transmission does not include pathlossOffset, the path loss corresponding to the uplink transmission (e.g., PUCCH transmission) of the associated spatial related information is determined based on the first path loss offset. When the spatial related information associated with the PUCCH transmission includes pathlossOffset and is indicated as a specific value (e.g., disable), the path loss corresponding to the uplink transmission (e.g., PUCCH transmission) of the associated spatial related information is not determined based on the first path loss offset.

[0436] Example 3: The spatial related information associated with the PUCCH transmission includes a third parameter, and the third parameter is used to indicate whether the path loss is determined based on the first path loss offset. At least part of the values ​​of the third parameter indicates that the path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset. For example, the values ​​of pathlossOffset include {0,1}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the spatial related information is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the spatial related information is determined based on the first path loss offset.

[0437] Example 4: The spatially relevant information associated with PUCCH transmission includes a fourth parameter, the fourth parameter being used to indicate that path loss is not determined based on the first path loss offset; or the fourth parameter is used to indicate that path loss is determined based on the first path loss offset and simultaneously indicates identification information of the first path loss offset, the identification information of the first path loss offset being used to determine the first path loss offset. At least some values ​​of the fourth parameter indicate that path loss is determined based on the first path loss offset and simultaneously indicate identification information of the first path loss offset. The UE determines the first path loss offset used to determine path loss based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset, and the values ​​of pathlossOffset include {0, 1, 2}. When the value is 0, it indicates that the path loss of the uplink transmission associated with the spatially relevant information is not determined based on the first path loss offset; when the value is 1, it indicates that the path loss of the uplink transmission associated with the spatially relevant information is determined based on the first path loss offset; and when the value is 2, it indicates that the path loss of the uplink transmission associated with the spatially relevant information is determined based on a third path loss offset.

[0438] In the above example, the first path loss offset and the third path loss offset are both indicated by the base station to the UE.

[0439] Optionally, when the uplink transmission is a PUSCH / PUCCH transmission, the PUSCH / PUCCH transmission includes multiple transmission opportunities / transmission layers. Determining whether to determine the path loss corresponding to the uplink transmission based on the first path loss offset includes: determining whether to determine the path loss corresponding to each transmission opportunity / transmission layer / repetition of the PUSCH / PUCCH transmission based on the first path loss offset.

[0440] The transmission of the PUSCH / PUCCH / SRS may be in a single TRP transmission mode or a multi-TRP transmission mode. In the case of a multi-TRP transmission mode, it may be an SDM transmission mode, a TDM transmission mode, an FDM transmission mode, or an SFN transmission mode, etc.

[0441] It should be noted that in an asymmetric downlink and uplink multi-TRP scenario, some uplink transmissions need to determine the path loss based only on the path loss reference signal, and some uplink transmissions need to determine the path loss based on the path loss reference signal and the first path loss offset.

[0442] In the prior art, there is no specific solution for determining which uplink transmissions use path loss offsets to determine path loss and which do not. The path loss determination method provided by the embodiments of the present disclosure enables a consistent understanding between the terminal and network-side equipment regarding which uplink transmissions use path loss offsets to determine path loss and which do not, thereby ensuring uplink transmission performance.

[0443] Optionally, after determining the path loss of the first signal, the transmit power of the first signal is determined based on the path loss of the first signal, and then the first signal is transmitted based on the transmit power of the first signal.

[0444] The present disclosure determines the path loss PL based on the path loss offset b,f,c (q d ) as follows:

[0445] Method 1: PL b,f,c (q d )=referenceSignalPower–RSRP1;

[0446] Where referenceSignalPower is the reference signal power, RSRP1 represents the RSRP determined based on high-layer filtering, and the RSRP used for filtering is the result of calculating the L1-RSRP of the path loss reference signal and the path loss offset (for example, the difference or ratio of the L1-RSRP of the path loss reference signal and the path loss offset).

[0447] Method 2:

[0448] PL b,f,c (q d )=referenceSignalPower-higher layer filtered RSRP+Δ, or,

[0449] PL b,f,c (q d )=referenceSignalPower-higher layer filtered RSRP-Δ.

[0450] Where Δ represents the path loss offset, referenceSignalPower is the reference signal power, and higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0451] Determine the path loss PL corresponding to the first signal, such as an uplink transmission (PUSCH / PUCCH / SRS / PRACH transmission) b,f,c (q d ), the terminal may further determine the transmission power of the uplink transmission based on the transmission power calculation formula of the uplink transmission.

[0452] For example, in NR systems, some PL-based b,f,c (q d ) An example of determining the transmission power of uplink transmission is as follows:

[0453] Example 1:

[0454] Among them, the uplink transmission is PUSCH transmission (the first signal is PUSCH), and PL in the above formula is b,f,c (q d ) can refer to some descriptions in the protocol (such as 3GPP protocol TS 38.213) for the determination method of other parameters besides .

[0455] Example 2:

[0456] Among them, the uplink transmission is PUCCH transmission (the first signal is PUCCH), and PL in the above formula is b,f,c (q d For the determination method of other parameters other than ), please refer to some descriptions in 3GPP protocol TS 38.213.

[0457] Example 3:

[0458] Among them, the uplink transmission is SRS transmission (the first signal is SRS), and PL in the above formula is b,f,c (q d ) can refer to some descriptions in the protocol (such as 3GPP protocol TS 38.213) for the determination method of other parameters besides .

[0459] Example 4: P PRACH,b,f,c (i) = min{P CMAX,f,c (i),P PRACH,target,f,c +PL b,f,c (q d )}[dBm]

[0460] Among them, the uplink transmission is PRACH transmission (the first signal is PRACH), and PL in the above formula is b,f,c (q d ) can refer to some descriptions in the protocol (such as 3GPP protocol TS 38.213) for the determination method of other parameters besides .
