In some network architectures, network-side equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated. Network-side equipment may include one or more TRPs (transmit and / or reception points). In some scenarios (such as high-speed scenarios), these TRPs may be remote radio head (RRH) nodes.

[0052] In order to facilitate a clearer understanding of the embodiments of the present invention, some relevant knowledge is first introduced.

[0053] In wireless communication systems, such as New Radio (NR) systems (also known as New Air Interface systems), 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 this path loss. Path loss is often referred to as simply path loss. Uplink signals include the Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), or Physical Random Access Channel (PRACH). All uplink transmission path losses are determined based on the Path Loss Reference Signal (PL-RS). PL-RS types include the Synchronization Signal / Physical Broadcast Channel Block (SSB) and the periodically transmitted Channel State Information Reference Signal (CSI-RS).

[0054] Taking PUSCH as an example, the transmission power of PUSCH is determined based on the path loss. The calculation is based on = Reference Signal Power (RSRP) – Reference Signal Received Power (RSRP) of the higher layer filter, where b is the index of the Bandwidth Part (BWP), f is the carrier ID, and c is the cell ID. ReferenceSignalPower is the identifier of the reference signal used to determine the path loss. The referenceSignalPower is determined by the high-level signaling ss-PBCH-BlockPower or ss-PBCH-BlockPower + powerControlOffsetSS (the default value is 0dB). RSRP is based on the UE The 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 via 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 transmit power relative to the SSB transmit power. If powerControlOffsetSS is not provided to the UE, the UE assumes the offset value is 0dB.

[0055] Due to UE transmission power limitations, the UL transmission performance of cell-edge UEs is typically 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, thereby achieving UL transmission performance similar to DL performance. Dense site deployment can lead to significant overlap in the downlink coverage of multiple sites. To reduce downlink interference between sites caused by overlapping coverage, and to conserve network power in low-load scenarios, network-side equipment may employ an asymmetric uplink and downlink multiple transmission and / or reception point (M-TRP) transmission scheme for each terminal, also known as an asymmetric uplink and downlink M-TRP scenario. Asymmetric uplink and downlink M-TRP transmission refers to an asymmetry between the number of TRPs (transmit and / or reception points) for uplink reception and the number of TRPs for downlink reception. For example, downlink transmission uses one TRP, but uplink reception can use two TRPs (i.e., asymmetric DL sTRP / UL mTRP). These TRPs can be intra-cell TRPs or inter-cell TRPs. Optionally, the asymmetry between UL and DL TRPs is viewed from the UE's perspective. That is, for the same network, some UEs use asymmetric uplink and downlink M-TRP transmission, while some UEs use the same number of TRPs for uplink and downlink transmission. Specifically, 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 with downlink channels shut down for a given period of time. The TRP in the present invention can also be referred to as a site, access point (AP), etc.

[0056] In this asymmetric uplink and downlink M-TRP transmission scenario, uplink transmissions to sites not performing downlink transmissions do not have corresponding downlink path loss reference signals. One method for determining 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 capable of downlink transmission). The base station then sends a path loss offset to the UE for inter-site path loss adjustment. For uplink transmissions to TRPs capable of downlink transmissions, the corresponding path loss should be determined based on the path loss reference signal, without the need for adjustment based on the path loss offset. That is, in asymmetric uplink and downlink M-TRP transmission scenarios, some uplink transmissions need to determine path loss based solely on the path loss reference signal, while other uplink transmissions need to determine path loss based on the path loss reference signal and the path loss offset.

[0057] 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 must indicate to the UE which uplink transmissions use pathloss offsets to determine pathloss, and which do not. There is no specific solution in existing technologies.

[0058] In a multi-carrier scenario, a UE communicates with multiple carriers (or component carriers). Different carriers may have different uplink and downlink transmission capabilities. In this case, some carriers may be capable of both uplink and downlink transmission, while others may only be capable of uplink transmission. In a multi-carrier scenario (also known as carrier aggregation (CA)), due to the asymmetry of uplink and downlink transmission carriers, carriers not performing downlink transmission do not have downlink pathloss signals transmitted on those carriers. One method for determining the pathloss corresponding to uplink transmission for a carrier without downlink transmission (e.g., carrier 1) is to determine the pathloss corresponding to the uplink transmission based on a pathloss reference signal (PLRS) from a DL carrier (i.e., a carrier capable of downlink transmission) and a pathloss offset (the pathloss offset corresponding to carrier 1) sent by the base station to the UE (i.e., the UE adjusts the pathloss based on the pathloss offset). For uplink transmission for carriers performing downlink transmission, the corresponding pathloss should be determined based on the PLRS, and no adjustment based on the pathloss offset is required. Specifically, in scenarios where multiple carriers perform asymmetric uplink and downlink transmission, it is necessary to determine path loss for uplink transmissions on some carriers based solely on the path loss reference signal (PLRS), while determining path loss for uplink transmissions on other carriers based on the PLRS and path loss offset. In this scenario, the base station needs to indicate to the UE which uplink transmissions use the path loss offset for path loss determination and which do not. No specific solution exists in the prior art. However, ensuring consistent understanding between network-side equipment (e.g., the base station) and terminals (e.g., the UE) regarding whether uplink transmissions use the path loss offset for path loss determination remains a pressing technical challenge.

[0059] FIG1 is a flow chart of a method for determining a path loss according to an embodiment of the present invention. The method is applied to a terminal. As shown in FIG1 , the method includes steps 101 to 102, wherein: 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 information indicating the first path loss offset.

[0060] 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.

[0061] The first signal may include at least one of the following: PUSCH; Physical Uplink Control Channel (PUCCH); SRS; PRACH.

[0062] Optionally, the network-side device sends first information to the terminal, the first information including 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.

[0063] Optionally, the first path loss offset and / or the identifier corresponding to the first path loss offset are indicated by first information, or the first path loss offset and / or the identifier corresponding to the first path loss offset are 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.

[0064] 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), and the first information is the configuration information of the PUSCH. The first information includes information used to indicate a path loss offset (for example, M bits are used to indicate a path loss offset from multiple path loss offsets, or information used to indicate 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. For the PUSCH transmission, the information used to indicate 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, namely, the first path loss offset corresponding to the PUSCH.

[0065] Step 102: performing 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 a first path loss offset; Alternatively, the path loss of the first signal is determined based on a path loss reference signal.

[0066] Optionally, when determining a first path loss offset corresponding to the first signal based on the first information, the first information indicates a value of the first path loss offset.

[0067] When determining a first path loss offset corresponding to a first signal based on 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.

[0068] 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 the value of the first path loss offset. Optionally, the network-side device indicates a value used to determine 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.

[0069] Optionally, according to the first information, performing the target operation includes the following steps: Step a, based on the first information, 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; 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 the path loss reference signal and the first path loss offset.

[0070] In the case where the first information includes information for 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; calculating the path loss of the first signal using formula (1) : Formula (1): =referenceSignalPower–higher layer filtered RSRP+PL-offset Among them, PL-offset is the first path loss offset, referenceSignalPower is the reference signal power, It is the identifier of the reference signal used to determine the path loss, and higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0071] 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 the path loss reference signal and the first path loss offset.

[0072] In the case where the first information includes information for 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).

[0073] Step d: When it is determined that 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.

[0074] In the case where the first information includes information indicating that the path loss is not determined based on the first path loss offset, the path loss of the first signal is determined not based on the first path loss offset. The path loss of the first signal is calculated using formula (2): : Formula (2): = referenceSignalPower – higher layer filtered RSRP 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 the 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.

[0075] Use formula (1) to calculate the path loss of the first signal : Formula (1): =referenceSignalPower–higher layer filtered RSRP+PL-offset Wherein, PL-offset is the preset path loss offset, and the value of the preset path loss offset is, for example, 0 dB. referenceSignalPower is the reference signal power, It is the identifier of the reference signal used to determine the path loss, and higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0076] 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.

[0077] For example, use formula (1) to calculate the path loss of the first signal : Formula (1): =referenceSignalPower–higher layer filtered RSRP+PL-offset Where PL-offset is the preset path loss offset. referenceSignalPower is the reference signal power. It is the identifier of the reference signal used to determine the path loss, and higher layer filtered RSRP is the reference signal received power of the higher layer filter.

[0078] It should be noted that steps b to f can be performed one by one.

[0079] 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 the path loss reference signal and the 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.

[0080] 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.

[0081] Optionally, types of path loss reference signals include synchronization signals / physical broadcast channel blocks and periodically transmitted channel status information reference signals. The path loss reference signal is derived from a TRP capable of downlink transmission, or it can be obtained through other means, which are not detailed in this embodiment. In this embodiment of the present invention, 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 a first signal indicated by a network-side device; or a target path loss reference signal indicated by the network-side device, where the target path loss reference signal is used for uplink transmission corresponding to multiple uplink channels or uplink signals.

[0082] In a path loss determination method provided by an embodiment of the present invention, 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 then 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 have consistent understanding of whether uplink transmission path loss is determined based on the path loss offset, thereby ensuring uplink transmission performance.

[0083] 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 that the path loss of the first signal is not determined 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 that the path loss of the first signal is not determined 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 that the path loss of the first signal is not determined 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.

[0084] 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 consistency in the 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.

[0085] 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 information associated with the TCI state corresponding to the first signal.

[0086] In an embodiment of the present invention, 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, may include at least one of the following: 1) 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 TCI state corresponding to the first signal and the relationship between the TCI state and the path loss offset; The relationship between the TCI state and the path loss offset is used to characterize whether the path loss corresponding to the uplink transmission associated with the TCI state is determined based on the path loss offset, or to determine the path loss offset corresponding to the uplink transmission associated with the TCI state.

[0087] 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. In this case, the terminal does not determine the uplink transmission path loss corresponding to the first TCI state based on the first path loss offset, and determines the uplink transmission path loss corresponding to the second TCI state based on the first path loss offset.

[0088] 2) 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 SRS resource set corresponding to the first signal and the relationship between the SRS resource set and the path loss offset; The relationship between the SRS resource set and the path loss offset is used to characterize whether the path loss corresponding to the uplink transmission associated with the SRS resource set is determined based on the path loss offset, or to indicate the path loss offset corresponding to the uplink transmission associated with the SRS resource set.

[0110] FIG2 is a second flow chart of a method for determining path loss according to an embodiment of the present invention. The method is applied to a network-side device. As shown in FIG2 , the method includes: Step 201: Sending first information to a terminal, the first information including information indicating whether to determine the path loss of a first signal based on a first path loss offset and / or information indicating the first path loss offset; the first information is used by the terminal to perform 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; Alternatively, the path loss of the first signal is determined based on a path loss reference signal.

[0111] Optionally, the network-side device sends first information to the terminal. After receiving the first information sent by the network-side device, the terminal determines, based on the first 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. The terminal may perform a target operation based on the first information, 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.

[0112] In the path loss determination method provided in an embodiment of the present invention, first information is sent to a terminal, 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, so that 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. This ensures that network-side equipment and the terminal have consistent understanding regarding whether the path loss of uplink transmission is determined based on the path loss offset, thereby ensuring uplink transmission performance.

[0113] Optionally, the first information includes at least one of the following: The associated information of the TCI state corresponding to the first signal; Configuration information of the SRS resource corresponding to the first signal; Configuration information of the SRS resource set corresponding to the first signal; Configuration information of the target SRS resource in the SRS resource set corresponding to the first signal; The first signal corresponds to the SRS transmission associated with the spatial correlation information; SRS resource set indication information for first signal transmission; Configuration information of the first signal; Spatial related information associated with the first signal; A power control parameter associated with the first signal.

[0117] Optionally, the spatial related information associated with the SRS transmission includes: information used to configure spatial filtering associated with the SRS transmission.

[0118] Optionally, the configuration information of the first signal includes at least one of the following: Information for configuring transmission parameters of the first signal; Information for configuring power control parameters of the first signal.

[0119] Optionally, the spatial-related information associated with the first signal includes: information used to configure spatial filtering associated with the first signal.

[0120] Here, the path loss determination method provided by the embodiment of the present invention is illustrated through several specific embodiments.

[0121] For the example where the first signal is SRS: Solution 1: Determine the SRS resource corresponding to the SRS, 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 can 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 configures 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.

[0122] Solution 2: Determine the SRS resource corresponding to the SRS. If the SRS resource configuration information includes information instructing the UE to determine path loss based on a path loss offset indicated by a 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 SRS resource configuration information does not include information instructing the UE to determine path loss based on a path loss offset indicated by the base station, or if the SRS resource configuration information does not include information instructing the UE to determine path loss based on a 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.

[0123] Option 1 and Option 2 can be used at the same time. For example: 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 that indicates 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, if the configuration information of the SRS resource is configured with information that indicates 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.

[0124] Solution 3: Determine the SRS resource set corresponding to the SRS. The SRS resource set is associated with a TCI state. If the base station configures, in the configuration information for the TCI state, information instructing the UE to determine path loss based on a 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 for the TCI state does not configure information instructing the UE to determine path loss based on the path loss offset indicated by the base station, or if information instructs the UE not to determine 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.

[0125] Solution 4: Determine the SRS resource set corresponding to the SRS. If the configuration information of the SRS resource set includes information instructing the UE to determine path loss based on a path loss offset indicated by a 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 does not include information instructing the UE to determine path loss based on a path loss offset indicated by the base station, or if the configuration information instructs the UE not to determine path loss based on a 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.

[0126] Option 3 and Option 4 can be used in combination. For example: 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 that indicates 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, if the configuration information of the SRS resource set is configured with information that indicates 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.

[0127] Solution 5: Determine an SRS resource set corresponding to an SRS, where the SRS resource set includes multiple SRS resources. The base station determines, 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 highest ranking, the SRS resource with the largest number, or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the lowest ranking), or the configuration information corresponding to a specific SRS resource (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 highest ranking, the SRS resource with the largest number, or the SRS resource with the largest ID (for example, SRS-ResourceId), or the SRS resource with the lowest ranking), 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.

[0128] In scheme 5-1, the UE determines the path loss corresponding to the SRS transmission based on the information indicating 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).

[0129] In 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 (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).

[0130] Option 5 can be used in conjunction with the previous option.

[0131] Note that in this embodiment of the present invention, the first signal may include multiple layers, multiple transmission opportunities, multiple repetitions, or multiple codewords. Optionally, the multiple layers, multiple transmission opportunities, multiple repetitions, or multiple codewords of the first signal include multiple groups, each group corresponding to a TCI state, TRP, SRS resource set, CORESETPoolIndex, antenna panel, etc. Different TCI states, TRPs, SRS resource sets, CORESETPoolIndex, and antenna panels may result in different methods for determining path loss (e.g., determining path loss based on a path loss offset, determining path loss based on a path loss reference signal, determining path loss based on a path loss offset of 0 dB, or determining path loss based on a path loss offset indicated by a network device).

[0132] For the example where the first signal is PUSCH: Solution 1) Determine the TCI state (one or more) associated with the PUSCH. For each TCI state, for a TCI state in which the TCI state configuration information is configured with information instructing 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 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 a TCI state in which the TCI state configuration information 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 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 PUSCH transmission layer / transmission opportunity / repetition / codeword corresponding to the TCI state based on the path loss offset indicated by the base station.

[0133] Solution 2) Determine the SRS resource set associated with the PUSCH, and 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.

[0134] Embodiment 1: The first information includes associated information of a TCI state corresponding to the first signal.

[0135] The terminal determines the TCI state corresponding to a first signal (such as an uplink transmission such as a PUSCH / PUCCH / SRS / PRACH transmission). Optionally, the TCI state corresponding to the first signal includes a TCI state for determining spatial-related information (e.g., a 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 a TCI state for determining spatial-related information (e.g., a transmit beam or spatial filter) and / or quasi-colocation (QCL) information (optionally, QCL Type-A and / or QCL Type-D) of an 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 indicating whether path loss is determined based on path loss offset and / or indicating the path loss offset.

[0136] The terminal determines, based on the associated 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; The terminal performs a target operation, the target operation including determining the path loss of the first signal based on the 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.

[0137] Optionally, the terminal determines, based on the associated 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 method of the first path loss offset corresponding to the first signal, including at least one of the following examples: Example 1: The TCI state association information 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, other naming methods are also possible). When the TCI state association information includes pathlossOffset, the terminal determines the path loss of the first signal associated with the TCI state (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset. When the TCI state association information does not include pathlossOffset, the terminal does not determine the path loss of the first signal associated with the TCI state (e.g., PUSCH / PUCCH / SRS / PRACH transmission) 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 0 dB).

[0138] Example 2: The TCI state association information may include a second parameter, which 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 first pathlossOffset. When the TCI state association information does not include pathlossOffset, the path loss corresponding to the first signal associated with the TCI state (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is determined based on the first path loss offset. When the TCI state association information includes pathlossOffset and pathlossOffset is indicated as a specific value (e.g., disabled), the path loss corresponding to the first signal associated with the TCI state (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is not determined based on the first path loss offset (optionally, indicating that the path loss of the first signal associated with the TCI state is determined based on a path loss offset of 0 dB).

[0139] Example 3: The TCI status-associated information includes a third parameter, which is used to indicate whether the path loss of the first signal is determined based on the first path loss offset. At least some values ​​of the third parameter indicate whether the path loss of the first signal is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset, and its values ​​include {0, 1}. When the value is 0, the path loss of the first signal associated with the TCI status 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 status is determined based on a path loss offset of 0 dB); when the value is 1, the path loss of the first signal associated with the TCI status is determined based on the first path loss offset. Of course, the value of 0 can also indicate that the path loss of the first signal associated with the TCI status 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 status 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 status is determined based on a path loss offset of 0 dB).

[0140] Example 4: The TCI state-associated information includes a fourth parameter, the fourth parameter being 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 being used to indicate that the path loss of the first signal is determined based on the first path loss offset and also 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 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 value of pathlossOffset includes {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.

[0141] 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.

[0142] Optionally, the TCI state-associated information is TCI state configuration information, which 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.

[0143] 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.

[0144] Embodiment 2: The first information includes configuration information of SRS resources corresponding to the first signal.

[0145] The terminal determines an SRS resource corresponding to a first signal (eg, uplink transmission such as PUSCH / PUCCH / SRS / PRACH transmission). The SRS resource corresponding to the first signal is an SRS resource configured or indicated by a base station for uplink transmission.

[0146] 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.

[0147] Taking PUSCH transmission as an example, an example of an SRS resource corresponding to a PUSCH transmission is: an 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).

[0148] Taking SRS transmission as an example, an example of an SRS resource corresponding to an SRS transmission is an SRS resource used to determine information such as resources corresponding to the SRS transmission.

[0149] Optionally, the SRS resources corresponding to 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.

[0150] Optionally, the configuration information of the SRS resource 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.

[0151] The terminal determines, based on 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.

[0152] The terminal performs a target operation, the target operation including: determining the path loss of the first signal based on the 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.

[0153] 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 method of the first path loss offset corresponding to the first signal, including at least one of the following examples: Example 1: The configuration information for an SRS resource may include a first parameter that indicates the path loss of a first signal determined based on a first path loss offset. For example, if the first parameter is named pathlossOffset, when the configuration information for the SRS resource includes pathlossOffset, the terminal determines the path loss of a first signal associated with the SRS resource (e.g., a PUSCH / PUCCH / SRS / PRACH transmission) based on the first path loss offset. If the configuration information for 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 0 dB).

[0154] Example 2: The SRS resource configuration information may include a second parameter that indicates 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 the SRS resource configuration information does not include pathlossOffset, the path loss of the first signal associated with the SRS resource is determined based on the first path loss offset. When the SRS resource configuration information includes pathlossOffset and indicates a specific value (e.g., 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 0 dB).

[0155] Example 3: The configuration information for an SRS resource includes a third parameter, which is used to indicate whether the path loss of the first signal is determined based on a first path loss offset. At least some values ​​of the third parameter indicate 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, and the values ​​of pathlossOffset include {0, 1}. When the value is 0, 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 0 dB); when the value is 1, the path loss of the first signal associated with the SRS resource is determined based on the first path loss offset.

[0156] Example 4: The SRS resource configuration information 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, 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 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 value of pathlossOffset includes {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 0 dB); 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.

[0157] 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.

[0161] 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 the 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, which 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.

[0162] 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 method of the first path loss offset corresponding to the first signal, including at least one of the following examples: Example 1: The configuration information for an SRS resource set includes a first parameter that indicates the path loss of a first signal determined based on a first path loss offset. For example, the first parameter is named pathlossOffset. When the configuration information for an 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 for an 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 0 dB).

[0163] Example 2: The configuration information for an SRS resource set may include a second parameter that indicates 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 the configuration information for the SRS resource set does not include pathlossOffset, the path loss of the first signal associated with the SRS resource set is determined based on the first path loss offset. When the configuration information for the SRS resource set includes pathlossOffset and indicates a specific value (e.g., 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 0 dB).

[0164] Example 3: The configuration information of an SRS resource set includes a third parameter, which is used to indicate whether the first signal path loss is determined based on a first path loss offset. At least some values ​​of the third parameter indicate that the first signal path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset, and the values ​​of pathlossOffset include {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 0 dB); 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.

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 for determining 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}.

The UE determines the first path loss offset for determining path loss based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset. For example, the value of pathlossOffset includes {0, 1, 2}. When the value is 0, it means 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 0 dB); when the value is 1, it means 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 means that the path loss of the uplink transmission associated with the PUSCH is determined based on the third path loss offset.

[0189] 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.

[0190] As some other examples, methods for determining, using PUSCH configuration information, whether the path loss corresponding to PUSCH transmission is determined based on the first path loss offset include: Example 1: PUSCH configuration information includes information indicating a relationship between TCI states and pathloss offsets. Based on this relationship, it is determined whether the pathloss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to each TCI state in PUSCH transmission is determined based on the first pathloss offset. For example, the information indicating the relationship between TCI states and pathloss offsets included in the PUSCH configuration information indicates the following: a first TCI state corresponds to a pathloss corresponding to a PUSCH transmission opportunity / layer / repetition not being determined based on the first pathloss offset, and a second TCI state corresponds to a pathloss corresponding to a PUSCH transmission opportunity / layer / repetition being determined based on the first pathloss offset. In this case, the UE does not determine the pathloss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to the first TCI state based on the first pathloss offset (optionally, the pathloss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to the first TCI state is determined based on a pathloss offset of 0 dB), and determines the pathloss corresponding to the PUSCH transmission opportunity / layer / repetition corresponding to the second TCI state based on the first pathloss offset.

[0191] For example, when the first information includes PUSCH configuration information and the PUSCH configuration information includes a relationship between a TCI state and a path loss offset, the terminal determines, based on the relationship between the TCI state and the path loss offset, whether to determine the path loss corresponding to the uplink transmission based on the first path loss offset; when it is determined that the path loss corresponding to the uplink transmission is determined based on the first path loss offset, the target operation performed by the terminal based on the first information is: determining the path loss based on a path loss reference signal corresponding to the uplink transmission and the first path loss offset.

[0192] In the case where it is determined that the path loss corresponding to the uplink transmission is not determined 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.

[0193] 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.

[0194] 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 the path loss corresponding to the uplink transmission is determined 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 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.

[0195] 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 the PUSCH transmission is determined based on the first pathloss offset.

[0196] 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 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 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.

[0197] 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.

[0198] 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 the path loss corresponding to the uplink transmission is determined 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 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.

[0199] As an example, the PUSCH configuration information is transmission parameter information used to configure the PUSCH, such as RRC signaling pusch-Config.

[0200] As another example, the PUSCH configuration information is power control parameter information used to configure the PUSCH.

[0201] Embodiment 7: The first information includes SRS resource set indication information used for first signal transmission.

[0202] The first signal may include at least one of the following: PUSCH; PUCCH; SRS; PRACH. The first signal is described as PUSCH as an example.

[0203] 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.

[0204] 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 method of the first path loss offset corresponding to the first signal, including at least one of the following examples: Example 1: The SRS resource set indication information may include a first parameter, which is used to indicate the path loss for the PUSCH determined based on a 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.

[0205] Example 2: The SRS resource set indication information may include a second parameter, which is used to indicate that the pathloss for the PUSCH is not determined based on the first pathloss offset. For example, the second parameter is named pathlossOffset. When the SRS resource set indication information does not include pathlossOffset, the pathloss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is determined based on the first pathloss offset. When the SRS resource set indication information includes pathlossOffset and indicates a specific value (e.g., disable), the pathloss corresponding to the uplink transmission associated with the PUSCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) is not determined based on the first pathloss offset.

[0206] Example 3: The SRS resource set indication information includes a third parameter, which is used to indicate whether the PUSCH pathloss is determined based on the first pathloss offset. At least some values ​​of the third parameter indicate that the PUSCH pathloss is determined based on the first pathloss offset. For example, the third parameter is named pathlossOffset, and the values ​​of pathlossOffset include {0, 1}. 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.

[0207] 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, with the identification information of the first pathloss offset used to determine the first pathloss offset. At least part of the value of the fourth parameter indicates that the PUSCH pathloss is determined based on the first pathloss offset and also indicates 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.

[0208] 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.

[0209] As some other examples, some methods for determining whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset using the SRS resource set indication information include: 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.

[0210] For example, when the value of the SRS resource set indication information is a specific value (such as 00 or 01), the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset.

[0211] 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.

[0212] Example 2: Determine the relationship between an SRS resource set and a 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 codebook-based PUSCH transmission (for example, txConfig is configured as codebook), the SRS resource set is an SRS resource set with usage of codebook. Optionally, when the PUSCH transmission is non-codebook PUSCH transmission (for example, txConfig is configured as nonCodebook), the SRS resource set is an SRS resource set with usage of nonCodebook.

[0213] For example, the relationship between the SRS resource set and the pathloss offset is as follows: the first SRS resource set corresponds to a pathloss for a PUSCH transmission that is not determined based on the first pathloss offset, and the second SRS resource set corresponds to a pathloss for a PUSCH transmission that is determined based on the first pathloss offset. Therefore, when the SRS resource set indication information indicates only the first SRS resource set, the pathloss for the PUSCH transmission is not determined based on the first pathloss offset; when the SRS resource set indication information indicates only the second SRS resource set, the pathloss for the PUSCH transmission is determined based on the first pathloss offset; and when the SRS resource set indication information indicates both the first and second SRS resource sets, the pathloss for the transmission timing / layer / repetition of the PUSCH transmission corresponding to the first SRS resource set is not determined based on the first pathloss offset, and the pathloss for the transmission timing / layer / repetition of the PUSCH transmission corresponding to the second SRS resource set is determined based on the first pathloss offset.

[0214] Optionally, an example of the relationship between the SRS resource set and the path loss offset is: 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; 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.

[0215] 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.

[0216] 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; based on the relationship, determine whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset.

[0217] For example, the relationship between TCI states and pathloss offsets is as follows: the first TCI state corresponds to a pathloss corresponding to the PUSCH transmission that is not determined based on the first pathloss offset, and the second TCI state corresponds to a pathloss corresponding to the PUSCH transmission that is determined based on the first pathloss offset. Therefore, when the SRS resource set indication information indicates the first TCI state, the pathloss corresponding to the PUSCH transmission is not determined based on the first pathloss offset; when the SRS resource set indication information indicates only the second TCI state, the pathloss corresponding to the PUSCH transmission is determined based on the first pathloss offset; and when the SRS resource set indication information indicates both the first and second TCI states, the pathloss corresponding to the transmission timing / layer / repetition of the PUSCH transmission corresponding to the first TCI state is not determined based on the first pathloss offset, and the pathloss corresponding to the transmission timing / layer / repetition of the PUSCH transmission corresponding to the second TCI state is determined based on the first pathloss offset.

[0218] Optionally, an example of the relationship between the TCI state and the path loss offset is: 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; 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.

[0219] 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.

[0220] 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.

[0221] 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; based on the relationship, determine whether the path loss corresponding to the PUSCH transmission is determined based on the first path loss offset.

[0222] Embodiment 8: The first information includes space-related information associated with the first signal.

[0223] The first signal may include at least one of the following: PUSCH; PUCCH; SRS; PRACH. The first signal is described as PUSCH as an example.

[0224] The terminal determines spatial correlation information associated with PUSCH transmission; based on the spatial correlation 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.

[0225] Optionally, the terminal determines, based on the spatial correlation 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: Example 1: The spatial correlation information associated with a PUSCH transmission includes a first parameter, which is used to indicate that pathloss is determined based on a first pathloss offset. For example, the first parameter is named pathlossOffset. When the spatial correlation information associated with a PUSCH transmission includes pathlossOffset, the terminal determines the pathloss corresponding to the uplink transmission associated with the spatial correlation information (e.g., PUSCH transmission) based on the first pathloss offset. When the spatial correlation information associated with a PUSCH transmission does not include pathlossOffset, the terminal does not determine the pathloss corresponding to the uplink transmission associated with the spatial correlation information (e.g., PUSCH transmission) based on the first pathloss offset.

[0226] Example 2: The spatial correlation information associated with a PUSCH transmission may include a second parameter, which is used to indicate that pathloss determination is not based on the first pathloss offset. For example, the second parameter is named pathlossOffset. When the spatial correlation information associated with the PUSCH transmission does not include pathlossOffset, the pathloss corresponding to the uplink transmission associated with the spatial correlation information (e.g., PUSCH transmission) is determined based on the first pathloss offset. When the spatial correlation information associated with the PUSCH transmission includes pathlossOffset and indicates a specific value (e.g., disable), the pathloss corresponding to the uplink transmission associated with the spatial correlation information (e.g., PUSCH transmission) is not determined based on the first pathloss offset.

[0227] Example 3: The spatial correlation information associated with a PUSCH transmission includes a third parameter, the third parameter being used to indicate whether path loss is determined based on a first path loss offset. At least some values ​​of the third parameter indicate that path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset, and the values ​​of pathlossOffset include {0, 1}. When the value is 0, the path loss of the uplink transmission associated with the spatial correlation information is not determined based on the first path loss offset; when the value is 1, the path loss of the uplink transmission associated with the spatial correlation information is determined based on the first path loss offset.

[0228] Example 4: The spatial correlation information associated with PUSCH transmission includes a fourth parameter, the fourth parameter being used to indicate that pathloss is not determined based on the first pathloss offset; or the fourth parameter being used to indicate that pathloss is determined based on the first pathloss offset and also indicating identification information of the first pathloss offset, the identification information of which is used to determine the first pathloss offset. At least some values ​​of the fourth parameter indicate that 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 for determining 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 spatial correlation information is not determined based on the first pathloss offset; when the value is 1, the pathloss of the uplink transmission associated with the spatial correlation information is determined based on the first pathloss offset; and when the value is 2, the pathloss of the uplink transmission associated with the spatial correlation information is determined based on a third pathloss offset.

[0229] 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.

[0230] Embodiment 9: The first information includes configuration information of PUCCH resources.

[0231] The first signal may include at least one of the following: PUSCH; PUCCH; SRS; PRACH. The first signal is described as PUCCH as an example.

[0232] The terminal determines configuration information of the PUCCH resource. Based on the configuration information of the PUCCH resource, 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.

[0233] 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: Example 1: The configuration information for a PUCCH resource may include a first parameter that indicates that pathloss is determined based on a first pathloss offset. For example, the first parameter is named pathlossOffset. When the configuration information for the PUCCH resource includes pathlossOffset, the terminal determines the pathloss corresponding to the uplink transmission associated with the PUCCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first pathloss offset. When the configuration information for the PUCCH resource does not include pathlossOffset, the terminal does not determine the pathloss corresponding to the uplink transmission associated with the PUCCH (e.g., PUSCH / PUCCH / SRS / PRACH transmission) based on the first pathloss offset.

[0234] Example 2: The configuration information for the PUCCH resource may include a second parameter, which is used to indicate that path loss is not determined based on the first path loss offset. For example, the second parameter is named pathlossOffset. When the configuration information for the PUCCH resource does not include pathlossOffset, 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 the configuration information for the PUCCH resource includes pathlossOffset and it 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. Example 3: The configuration information for the PUCCH resource includes a third parameter, which is used to indicate whether path loss is determined based on the first path loss offset. At least some values ​​of the third parameter indicate that 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 means 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 means that the path loss of the uplink transmission associated with the PUCCH is determined based on the first path loss offset.

[0235] Example 3: PUCCH resource configuration information includes a third parameter, the third parameter being used to indicate whether path loss is determined based on a first path loss offset. At least some values ​​of the third parameter indicate that path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset, and the values ​​of pathlossOffset include {0, 1}. When the value is 0, 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, the path loss of the uplink transmission associated with the PUCCH is determined based on the first path loss offset.

[0236] Example 4: The configuration information for the PUCCH resource includes a fourth parameter, which is 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 also 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 part of the value of the fourth parameter indicates that path loss is determined based on the first path loss offset and also indicates 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 its values ​​include {0, 1, 2}. When the value is 0, 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, the path loss of the uplink transmission associated with the PUCCH is determined based on the first path loss offset; and when the value is 2, the path loss of the uplink transmission associated with the PUCCH is determined based on a third path loss offset.

[0237] 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.

[0238] Embodiment 10: The first information includes information for indicating space-related information associated with PUCCH resources.

[0239] The first signal may include at least one of the following: PUSCH; PUCCH; SRS; PRACH. The first signal is described as PUCCH as an example.

[0240] The terminal determines spatial correlation information associated with PUCCH transmission; based on the spatial correlation information associated with 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.

[0241] Optionally, the terminal determines, based on the spatial correlation 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: Example 1: The spatial correlation information associated with a PUCCH transmission includes a first parameter, which is used to indicate that pathloss is determined based on a first pathloss offset. For example, the first parameter is named pathlossOffset. When the spatial correlation information associated with the PUCCH transmission includes pathlossOffset, the terminal determines the pathloss corresponding to the uplink transmission associated with the spatial correlation information (e.g., PUCCH transmission) based on the first pathloss offset. When the spatial correlation information associated with the PUCCH transmission does not include pathlossOffset, the terminal does not determine the pathloss corresponding to the uplink transmission associated with the spatial correlation information (e.g., PUCCH transmission) based on the first pathloss offset.

[0242] Example 2: The spatial-related information associated with a PUCCH transmission may include a second parameter, which is used to indicate that pathloss determination is not based on the first pathloss offset. For example, the second parameter is named pathlossOffset. When the spatial-related information associated with the PUCCH transmission does not include pathlossOffset, the pathloss corresponding to the uplink transmission (e.g., PUCCH transmission) associated with the spatial-related information is determined based on the first pathloss offset. When the spatial-related information associated with the PUCCH transmission includes pathlossOffset and indicates a specific value (e.g., disable), the pathloss corresponding to the uplink transmission (e.g., PUCCH transmission) associated with the spatial-related information is not determined based on the first pathloss offset.

[0243] Example 3: The spatial correlation information associated with a PUCCH transmission includes a third parameter, the third parameter being used to indicate whether path loss is determined based on a first path loss offset. At least some values ​​of the third parameter indicate that path loss is determined based on the first path loss offset. For example, the third parameter is named pathlossOffset, and the values ​​of pathlossOffset include {0, 1}. When the value is 0, the path loss of the uplink transmission associated with the spatial correlation information is not determined based on the first path loss offset; when the value is 1, the path loss of the uplink transmission associated with the spatial correlation information is determined based on the first path loss offset.

[0244] Example 4: The spatial correlation 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 being used to indicate that path loss is determined based on the first path loss offset and also 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 part of the value of the fourth parameter indicates that path loss is determined based on the first path loss offset and also indicates identification information of the first path loss offset. The UE determines the first path loss offset used for path loss determination based on the identification information of the first path loss offset. For example, the fourth parameter is named pathlossOffset, and its values ​​include {0, 1, 2}. When the value is 0, the path loss of the uplink transmission associated with the spatial correlation information is not determined based on the first path loss offset; when the value is 1, the path loss of the uplink transmission associated with the spatial correlation information is determined based on the first path loss offset; and when the value is 2, the path loss of the uplink transmission associated with the spatial correlation information is determined based on a third path loss offset.

[0245] 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.

[0246] Optionally, when the uplink transmission is 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.

[0247] The transmission of PUSCH / PUCCH / SRS can be in a single TRP transmission mode or a multi-TRP transmission mode. In the case of a multi-TRP transmission mode, it can be an SDM transmission mode, a TDM transmission mode, an FDM transmission mode, or an SFN transmission mode.

[0248] It should be noted that in the 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.

[0249] 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 invention enables terminals and network-side equipment to have a consistent understanding of which uplink transmissions use path loss offsets to determine path loss and which do not, thereby ensuring uplink transmission performance.

[0250] 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.

[0251] The present invention determines path loss based on path loss offset The way is as follows: Method 1: referenceSignalPower –RSRP 1; Where referenceSignalPower is the reference signal power, RSRP 1 represents the RSRP determined based on high-level 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).
