Description

Method, device, equipment and medium for determining uplink signal transmission power

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on November 17, 2023, with application number 202311537853.4 and application name “Method, device, equipment and medium for determining uplink signal transmission power”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a method, apparatus, device, and medium for determining uplink signal transmission power. Background Art

[0003] In related systems, a terminal needs to determine a downlink path loss based on a downlink signal, and then determine the transmission power of the uplink signal based on the downlink path loss. All uplink transmission path losses are determined based on the path loss reference signal.

[0004] Currently, due to limitations on terminal transmission power, the uplink (UL) transmission performance of cell-edge terminals is typically far inferior to that of downlink (DL) transmission. 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. Distributed MIMO systems can also be referred to as multiple transmission and / or receipt point (M-TRP) systems, including intra-cell and / or inter-cell multiple TRPs. Dense site deployment can lead to significant overlap in the downlink coverage of multiple sites. To reduce downlink interference between sites due to overlapping coverage, and to conserve network energy in low-load scenarios, downlink transmission at some sites can be temporarily disabled, allowing them to receive only uplink transmissions. These sites can be referred to as uplink-only transmission and / or receipt points (TRPs), or TRPs without downlink transmission, or sites dedicated only to uplink reception. These UL Rx only TRPs may be sites without DL transmission channels, or sites with DL transmission channels but with the downlink channels turned off for a given period of time.

[0005] For UL Rx only TRP, because the site cannot send a downlink reference signal, the terminal cannot calculate the path loss based on the downlink reference signal of the site, and thus cannot determine the transmission power of the uplink signal. Summary of the Invention

[0046] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0047] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0048] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0049] In order to facilitate understanding of the solutions of the present disclosure, the relevant contents involved in the present disclosure are first introduced.

[0050] In wireless communication systems (such as New Radio (NR) systems and Long Term Evolution (LTE) systems), for the transmission of uplink signals (such as Physical Uplink Shared Channel (PUSCH), Sounding Reference Signaling (SRS), and Physical Random Access Channel (PRACH)), the terminal needs to determine the path loss (path loss) based on a path loss reference signal (PL-RS), and then determine the transmission power of the uplink signal based on the path loss. PL-RS is a downlink signal, such as a synchronization signal / physical broadcasting channel block (SSB) or a channel state information reference signal (CSI-RS).

[0051] Taking PUSCH as an example, in the current NR system, the calculation formula for its transmission power is as follows:

[0052] For a PUSCH transmission opportunity i on the activated uplink (UL) bandwidth part (BWP) b of carrier f in serving cell c using parameter set configuration indexed j and PUSCH power control adjustment state indexed l, the transmission power P PUSCH,b,f,c (i,j,q d ,l) is:

[0053] Among them, the path loss PL b,f,c (q d ) is calculated based on

[0054] PL b,f,c (q d )=referenceSignalPower-higher layer filtered RSRP determination, where q dThe reference signal (PL-RS) used to determine the path loss is identified. The referenceSignalPower is determined by the ss-PBCH-BlockPower or ss-PBCH-BlockPower+powerControlOffsetSS sent by the higher layer signaling (the default value is 0dB). RSRP is based on q d The reference signal receiving power (RSRP) determined by the corresponding reference signal. If the UE is not configured to receive periodic CSI-RS, referenceSignalPower is determined based on the ss-PBCH-BlockPower sent by the base station through high-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 an offset value for the transmission power of the CSI-RS relative to the SSB transmission power. If powerControlOffsetSS is not provided to the UE, the UE assumes a default offset value of 0dB.

[0055] Due to the limitation of UE transmission power, the UL transmission performance of UE at the edge of the cell is usually far inferior to the DL transmission performance. In a distributed MIMO system, the distributed deployment of multiple sites (i.e., TRPs) can reduce path loss, so that UL transmission can achieve performance similar to DL. Distributed MIMO systems can also be called multi-TRP systems, M-TRP systems, etc., including intra-cell and / or inter-cell multiple TRPs. Dense site deployment will cause the downlink coverage of multiple sites to overlap severely. On the one hand, in order to reduce the downlink interference between sites with overlapping coverage, and on the other hand, for the consideration of network energy saving in low-load scenarios, the downlink transmission of some sites can be temporarily shut down and only used to receive uplink transmission. These sites can be called UL Rx only TRPs, or TRPs without downlink transmission, or sites used only for uplink reception, etc. These UL Rx only TRPs can be sites without DL transmission channels, or sites with DL transmission channels but with downlink channels shut down for a given time period.

[0056] For UL Rx only TRP, because the site cannot send a downlink reference signal, the terminal cannot calculate the path loss based on the downlink reference signal of the site, and thus cannot determine the transmission power of the uplink signal.

[0057] In order to solve the above technical problems, the embodiments of the present disclosure provide a method, device, equipment and medium for determining the uplink signal transmission power, wherein the method and the device are based on the same application concept. Since the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0058] This is a flow chart of a method for determining uplink signal transmission power provided in an embodiment of the present disclosure, which is applied to, or executed by, a terminal. The method may include:

[0059] Step 101, receiving a first signal and offset information sent by a network device;

[0060] Here, the network device may be a base station or a core network, and the base station may include one or more cells providing services to the terminal. The base station may include multiple TRPs, wherein the multiple TRPs include a UL Rx only TRP and other TRPs (i.e., TRPs that can be oriented to both uplink and downlink transmissions). Depending on the specific application scenario, the base station can also be called an access point, or it can be a device in the access network that communicates with a wireless terminal device through one or more sectors on the air interface. It can also be called a node B (Node B), an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a wireless local area network (Wireless Local Area Networks, WLAN) access point, a wireless fidelity (Wireless Fidelity, WiFi) node or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0061] In some embodiments, the first signal includes a reference signal corresponding to a first signal resource. In some embodiments, the first signal is a reference signal transmitted based on the first signal resource. That is, the first signal is transmitted on the time-frequency domain resources corresponding to the first signal resource. In some embodiments, the first signal includes at least one of the following: an SSB; a CSI-RS. In some embodiments, the first signal resource is a downlink signal resource, including at least one of the following: an SSB resource; a CSI-RS resource.

[0062] In some embodiments, the first signal resource is a periodic signal resource.

[0063] In some embodiments, the first signal resource is a semi-persistent signal resource.

[0064] In some embodiments, the first signal resource is a non-periodic signal resource. In some embodiments, the network device sends the offset information by at least one of the following:

[0065] Radio Resource Control (RRC) signaling;

[0066] Media Access Control Control Element (MAC-CE) signaling;

[0067] Downlink Control Information (DCI) signaling.

[0068] In some embodiments, the offset information includes path loss offset information and / or RSRP offset information, wherein the path loss offset information is used to indicate / determine the path loss offset, and the RSRP offset information is used to indicate / determine the RSRP offset. Then, the terminal may determine the path loss offset and / or RSRP offset based on the offset information.

[0069] In some embodiments, the path loss offset is an offset between a path loss corresponding to the second signal and a path loss corresponding to the first signal.

[0070] In some embodiments, the RSRP offset includes one or more of the following:

[0071] an offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP, where the first TRP is the TRP corresponding to the first signal and the second TRP is the TRP corresponding to the second signal;

[0072] An offset between the RSRP corresponding to the second control resource pool index and the RSRP corresponding to the first control resource pool index, wherein the first control resource pool index is the control resource pool index corresponding to the first signal, and the second control resource pool index is the control resource pool index corresponding to the second signal;

[0073] an offset between an RSRP corresponding to a second TCI state and an RSRP corresponding to a first TCI state, where the first TCI state is the TCI state corresponding to the first signal and the second TCI state is the TCI state corresponding to the second signal;

[0074] an offset between an RSRP corresponding to a second cell and an RSRP corresponding to a first cell, where the first cell is the cell corresponding to the first signal and the second cell is the cell corresponding to the second signal;

[0075] an offset between an RSRP corresponding to a second SRS resource set and an RSRP corresponding to a first SRS resource set, where the first SRS resource set is an SRS resource set corresponding to the first signal and the second SRS resource set is an SRS resource set corresponding to the second signal;

[0076] an offset between an RSRP corresponding to a second carrier and an RSRP corresponding to a first carrier, where the first carrier is a carrier corresponding to the first signal and the second carrier is a carrier corresponding to the second signal;

[0077] The offset between the RSRP corresponding to the second beam and the RSRP corresponding to the first beam, where the first beam is the beam corresponding to the first signal, and the second beam is the beam corresponding to the second signal.

[0078] The order in which the network device sends the first signal and the offset information to the terminal may not be in particular order. For example, the network device sends the first signal and the offset information to the terminal at the same time. For another example, the network device sends the offset information after sending the first signal to the terminal. For another example, the network device sends the first signal after sending the offset information to the terminal. For another example, the first signal includes multiple signals, the offset information indicates an offset, the network device sends the offset information after sending some first signals, and then continues to send the first signal. For another example, the first signal includes multiple signals, the offset information also includes multiple signals, and the network device sends the first signal and the offset information alternately. For example, the network device sends some offset information after sending some first signals, and then continues to send the first signal, and then continues to send the offset information; for another example, the network device sends one offset information each time it sends a first signal, etc.

[0079] Step 102: determining a path loss corresponding to a second signal based on the first signal and the offset information, and determining a transmission power of the second signal based on the path loss corresponding to the second signal;

[0080] In some embodiments, the second signal is an uplink signal. In some embodiments, the second signal includes at least one of the following: PUSCH, Physical Uplink Control Channel (PUCCH), PRACH, SRS, Demodulation Reference Signal (DMRS).

[0081] The path loss corresponding to the second signal refers to the path loss of the second signal during transmission (sent from the terminal to the network device).

[0082] In some embodiments, the terminal calculates the path loss corresponding to the second signal sent to the UL Rx only TRP based on the first signal (downlink signal) and offset information sent by the network device from a TRP with DL transmission, and then determines the transmission power of the second signal (uplink signal).

[0083] Alternatively, in step 103, the path loss corresponding to the first signal is determined based on the first signal, the path loss offset and / or the reference signal received power RSRP offset is determined based on the offset information, and the transmission power of the second signal is determined based on the path loss corresponding to the first signal, and the path loss offset and / or RSRP offset.

[0084] The path loss corresponding to the first signal refers to the path loss of the first signal during transmission (sent from the network device to the terminal).

[0085] In some embodiments, the terminal obtains the path loss corresponding to the first signal by measuring the first signal based on the first signal (downlink signal) sent by the network device from a TRP with DL transmission; then, the transmission power of the second signal (uplink signal) sent to the UL Rx only TRP is calculated based on the path loss corresponding to the first signal and the path loss offset and / or RSRP offset determined based on the offset information.

[0086] In some embodiments, when the application scenario of the embodiments of the present disclosure is a UL Rx only TRP scenario, the first signal (downlink signal) does not come from the UL Rx only TRP, but rather comes from a signal from another TRP that transmits a downlink signal. The second signal (uplink signal) is sent to the UL Rx only TRP. In this way, the terminal can calculate the path loss based on the downlink signal transmitted by the other TRP, and then determine the transmission power of the uplink signal. Of course, the method of the embodiments of the present disclosure is not only applicable to scenarios configured with UL Rx only TRP, but also to scenarios in which uplink signals are generally transmitted. For scenarios in which uplink signals are generally transmitted, the transmission power of the uplink signal can also be determined using the method provided by the embodiments of the present disclosure.

[0087] In some embodiments, the first signal and the second signal have at least one of the following relationships:

[0088] The first signal and the second signal correspond to different control resource set pool indexes;

[0089] The first signal and the second signal correspond to different transmission reception points TRP;

[0090] The first signal and the second signal correspond to different Transmission Control Information (TCI) states;

[0091] The first signal and the second signal correspond to different sounding reference signal SRS resource sets;

[0092] The first signal and the second signal correspond to different cells;

[0093] The first signal and the second signal correspond to different carriers.

[0094] When the first signal and the second signal correspond to different TRPs, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP. Determining the path loss corresponding to the second signal based on the first signal and the offset information can achieve the determination of the path loss of the uplink signal of another TRP based on the downlink signal of one TRP, and then determine the transmission power of the uplink signal. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the path loss of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission, and then determine the transmission power of the uplink signal. Determining the path loss corresponding to the first signal based on the first signal, determining the path loss offset and / or reference signal received power RSRP offset based on the offset information, and determining the transmission power of the second signal based on the path loss corresponding to the first signal and the path loss offset and / or RSRP offset can achieve the determination of the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, the terminal can calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0095] The signals corresponding to different control resource set pools may correspond to different transmission antennas, different beams, different TRPs, etc. When the first signal and the second signal correspond to different control resource set pools (i.e., different control resource set pool indexes CORESETPoolIndex), the first signal is a downlink signal corresponding to one / a group of transmission antennas / beams / TRPs, and the second signal is an uplink signal corresponding to another / a group of transmission antennas / beams / TRPs. Based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to another / a group of transmission antennas / beams / TRPs based on the downlink signal of one / a group of transmission antennas / beams / TRPs. In particular, in a multi-TRP scenario, different TRPs can be configured as different control resource set pool indexes CORESETPoolIndex. When the first signal and the second signal correspond to different CORESETPoolIndex, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, the terminal can calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0096] When the first signal and the second signal correspond to different TCI states, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to another TCI state based on the downlink signal corresponding to one TCI state. In some embodiments, different TCI states correspond to different beams and / or TRPs, etc. In particular, in a multi-TRP scenario, when different TRPs can be configured as different TCI states, and the first signal and the second signal correspond to different TCI states, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP, then based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0097] When the first signal and the second signal correspond to different SRS resource sets, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to another SRS resource set based on the downlink signal corresponding to one SRS resource set. In particular, different SRS resource sets can correspond to different beams and / or TRPs, etc. In particular, in a multi-TRP scenario, when different TRPs are configured to correspond to different SRS resource sets, when the first signal and the second signal correspond to different SRS resource sets, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0098] When the first signal and the second signal correspond to different cells, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to one cell based on the downlink signal corresponding to another cell. In particular, in a multi-TRP scenario, different TRPs can be configured as different cells. Then, when the first signal and the second signal correspond to different cells, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP. Based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, the terminal can calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0099] When the first signal and the second signal correspond to different carriers, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to one carrier based on the downlink signal corresponding to another carrier. In particular, in a multi-TRP scenario, different TRPs can be configured as different carriers. When the first signal and the second signal correspond to different carriers, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP, then based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0100] In some optional embodiments, in step 102, determining the path loss corresponding to the second signal based on the first signal and the offset information specifically includes:

[0101] Step 1021: Determine a first RSRP based on the first signal;

[0102] In some embodiments, the first RSRP is the layer 1 (i.e., physical layer) reference signal received power L1-RSRP. In some embodiments, the first RSRP is the RSRP obtained by filtering the layer 1 (i.e., physical layer) reference signal received power L1-RSRP. Filtering includes high-level filtering, or a method of filtering multiple measurement quantities using some filter coefficients. For example, to obtain an average value for multiple measurement quantities (or multiple values), the average value can be a linear average value, a weighted average value, or another type of average value. A method of performing high-level filtering on the measurement quantity Mn (replacing Mn with L1-RSRP is filtering L1-RSRP) is as follows: F n =(1-a)*F n-1 +a*M n

[0103] Where M n is the latest measurement result received from the physical layer (e.g., L1-RSRP in the embodiment of the present disclosure), and n is an integer greater than or equal to 1; F n is the updated filtered measurement result (eg, high-level filtered RSRP in the disclosed embodiment); F n-1 is the last filtered measurement result, where F0 is set to M1 (i.e., the first measurement result received from the physical layer); for MeasObjectNR (NR measurement object), where k iThe filter coefficient for the corresponding measurement quantity of the i-th QuantityConfigNR in quantityConfigNR-List, where i is indicated by quantityConfigIndex in MeasObjectNR; for other measurements, a=1 / 2 (k / 4) , where k is the filter coefficient of the corresponding measurement quantity received by quantityConfig (measurement quantity configuration); for the Universal Radio Access Frequency Division Duplex (UTRA-FDD) system, a = 1 / 2 (k / 4) , where k is the filter coefficient of the corresponding measurement quantity received in quantityConfigUTRA-FDD (UTRA-FDD measurement quantity configuration) in QuantityConfig (measurement quantity configuration).

[0104] Replace the measurement quantity Mn with L1-RSRP, then the first RSRP is F obtained based on the above formula n .

[0105] In some embodiments, the first RSRP is the RSRP obtained by performing higher-layer filtering using multiple L1-RSRPs, including the L1-RSRP corresponding to the first signal. In some embodiments, the first RSRP is the higher-layer filtered RSRP determined by performing higher-layer filtering on the L1-RSRP corresponding to the first signal, which may be represented by higher-layer filtered RSRP. When the first signal is a signal corresponding to a periodic reference signal resource, an L1-RSRP can be obtained for each transmission corresponding to the periodic reference signal resource. In this case, the terminal can determine the higher-layer filtered RSRP, i.e., the first RSRP, based on the higher-layer filtering calculation formula in the above example.

[0106] In some embodiments, the first RSRP is a filtered RSRP determined by filtering a calculation result of the L1-RSRP corresponding to the first signal and a path loss offset and / or RSRP offset indicated by the offset information. In some embodiments, each of the calculation results is a calculation result of the L1-RSRP corresponding to the first signal and a path loss offset and / or RSRP offset indicated by the offset information, for example, a difference calculation result or a division calculation result of the L1-RSRP corresponding to the first signal and a path loss offset and / or RSRP offset indicated by the offset information.

[0107] In some embodiments, the L1-RSRP for a signal is defined as the linear average of the power contributions (in watts) of the resource elements carrying the signal. In some embodiments, the RSRP is expressed in watts. In some embodiments, the RSRP is expressed in dB or dBm.

[0108] Step 1022: Determine a path loss corresponding to the second signal based on the first RSRP and the offset information.

[0109] In some embodiments, the terminal determines a path loss corresponding to the second signal based on the first RSRP, the offset information, and the reference power.

[0110] The reference power may be indicated by the network device, or may be agreed upon in advance between the terminal and the network device (for example, agreed upon through signaling interaction, or agreed upon through a protocol, etc.).

[0111] Use PL b,f,c (q d ) represents the path loss corresponding to the second signal. Some examples of determining the path loss corresponding to the second signal transmitted on cell c, carrier f, and activated BWP b are:

[0112] PL b,f,c (q d )=referenceSignalPower–RSRP1;

[0113] ReferenceSignalPower represents a reference power, RSRP1 represents an RSRP determined by filtering multiple third RSRPs, and each third RSRP is a calculation result of the L1-RSRP of a first signal and a path loss offset / RSRP offset (for example, the difference or ratio of the L1-RSRP of the first signal to the path loss offset / RSRP offset). In this example, the offset information indicates multiple path loss offsets and / or multiple RSRP offsets, and the first signal includes multiple first signals.

[0114] Use PL b,f,c (q d ) represents the path loss corresponding to the second signal, higher layer filtered RSRP represents the first RSRP, and Δ represents the path loss offset and / or RSRP offset determined by the terminal based on the offset information. Some examples of determining the path loss corresponding to the second signal transmitted on cell c, carrier f, and activated BWP b are:

[0115] PL b,f,c (q d)=referenceSignalPower-higher layer filtered RSRP+Δ, or,

[0116] PL b,f,c (q d )=referenceSignalPower-higher layer filtered RSRP-Δ.

[0117] In the above formulas, q d is the identifier (index) of the first signal, b is the identifier (index) of the activated BWP, f is the carrier identifier, and c is the cell identifier. referenceSignalPower is the reference power indicated to the terminal by the network device (such as the base station) through high-layer signaling. For example, the base station indicates referenceSignalPower through ss-PBCH-BlockPower or ss-PBCH-BlockPower and powerControlOffsetSS (the default value is 0dB) sent by the base station through high-layer signaling, and the UE determines the referenceSignalPower based on the ss-PBCH-BlockPower or ss-PBCH-BlockPower+powerControlOffsetSS sent by the base station through high-layer signaling. Higher layer filtered RSRP is the reference power of the UE based on q d The RSRP of the corresponding reference signal (ie, the first signal) is determined by performing high-layer filtering on the L1-RSRP. In some embodiments, the filter configuration of the high-layer filtering is indicated by a network device.

[0118] In some embodiments, when the UE is not configured to receive periodic CSI-RS, referenceSignalPower is determined by the UE based on ss-PBCH-BlockPower sent by the base station through higher-layer signaling. When the UE is configured to receive periodic CSI-RS, referenceSignalPower is determined based on ss-PBCH-BlockPower or powerControlOffsetSS, where powerControlOffsetSS indicates the offset of the CSI-RS transmission power relative to the SSB transmission power. If powerControlOffsetSS is not indicated to the UE, the UE assumes that the offset is 0 dB.

[0119] In some embodiments, PL b,f,c (q d ) is in dB or dBm.

[0120] The path loss PL corresponding to the second signal is determined b,f,c (q d ), the terminal may further determine the transmission power of the second signal based on the transmission power calculation formula of the second signal.

[0121] For example, in the NR system, some path loss PL corresponding to the second signal b,f,c (q d ) An example of determining the transmission power of the second signal is as follows:

[0122] Example 1:

[0123] The second signal is a PUSCH signal, and PL in the above formula b,f,c (q d For the determination method of other parameters other than ), please refer to some descriptions in 3GPP protocol TS 38.213.

The offset between the RSRP corresponding to the second beam and the RSRP corresponding to the first beam is the offset value between the RSRP of the signal corresponding to the first SRS resource measured at the first TRP and the RSRP of the signal corresponding to the second SRS resource measured at the second TRP. The signal corresponding to the first SRS resource is sent to the first TRP via the first beam, and the signal corresponding to the second SRS resource is sent to the second TRP via the second beam.

[0163] In some embodiments, the offset information includes multiple path loss offset information and / or multiple RSRP offset information.

[0164] In some embodiments, the plurality of path loss offset information corresponds to a second RSRP and / or the plurality of path loss offset information corresponds to the first signal, and the second RSRP is used to determine the first RSRP. In some embodiments, the second RSRP is the L1-RSRP of the first signal, and the first RSRP is an RSRP obtained by filtering the plurality of L1-RSRPs including the second RSRP (e.g., a higher-layer filtered RSRP).

[0165] In some embodiments, the correspondence between the multiple pieces of path loss offset information and the second RSRPs is such that each piece of path loss offset information corresponds to one second RSRP. In some embodiments, the correspondence between the multiple pieces of path loss offset information and the second RSRPs is a one-to-one correspondence. That is, the multiple second RSRPs correspond one-to-one to the multiple pieces of path loss offset information. In this case, the terminal can determine a power adjustment value for each second RSRP based on its corresponding path loss offset value, thereby better determining the transmission power of the second signal.

[0166] In some embodiments, the correspondence between the multiple pieces of path loss offset information and the first signal is such that each piece of path loss offset information corresponds to one first signal. In some embodiments, the correspondence between the multiple pieces of path loss offset information and the first signal is a one-to-one correspondence, i.e., the multiple pieces of path loss offset information have a one-to-one correspondence with multiple first signals. In this case, the terminal can determine a power adjustment value for each first signal based on its corresponding path loss offset value, thereby better determining the transmission power of the second signal.

[0167] In some embodiments, the multiple RSRP offset information has a corresponding relationship with the second RSRP, and / or the multiple RSRP offset information has a corresponding relationship with the first signal.

[0168] In some embodiments, the correspondence between the multiple RSRP offset information and the second RSRP is such that each RSRP offset information corresponds to one second RSRP. In some embodiments, the correspondence between the multiple RSRP offset information and the second RSRP is a one-to-one correspondence.

In this case, the terminal can determine an adjusted RSRP value for each second RSRP based on its corresponding RSRP offset information, thereby better determining the transmission power of the second signal.

[0169] In some embodiments, the correspondence between the multiple RSRP offset information and the first signal is such that each RSRP offset information corresponds to one first signal. In some embodiments, the correspondence between the multiple RSRP offset information and the first signal is a one-to-one correspondence, i.e., the multiple RSRP offset information domains have a one-to-one correspondence with multiple first signals. In this case, the terminal can determine an adjusted RSRP value for each first signal based on its corresponding RSRP offset value, thereby better determining the transmission power of the second signal.

[0170] In some embodiments, the number of the path loss offset information is equal to the number of the second RSRPs used to determine the first RSRP. In this case, the network device sends a corresponding path loss offset information for each second RSRP.

[0171] In some embodiments, the amount of path loss offset information is less than the number of second RSRPs used to determine the first RSRP. In this case, the network device only sends the corresponding path loss offset information for some of the second RSRPs, or multiple second RSRPs share the same path loss offset information. This can save the overhead of path loss offset information. For example, if a piece of path loss offset information sent by the network device is applicable for a period of time, during this period, the terminal can determine the higher-layer filtered RSRP (first RSRP) based on multiple second RSRPs, but corresponding to the same path loss offset information.

[0172] In some optional embodiments, in step 102, determining the path loss corresponding to the second signal based on the first signal and the offset information may specifically include:

[0173] determining a path loss offset based on filtering offset values ​​corresponding to a plurality of path loss offset information included in the offset information;

[0174] A path loss corresponding to the second signal is determined based on the first RSRP and the path loss offset.

[0175] In some embodiments, after obtaining the path loss offset Δ through the above filtering, the path loss corresponding to the second signal may be determined based on the reference power, the first RSRP, and the path loss offset. That is, based on the following formula:

[0176] referenceSignalPower-higher layer filtered RSRP+Δ, or,

[0177] Reference Signal Power - higher layer filtered RSRP - Δ is used to determine a path loss corresponding to the second signal. Thereafter, a transmission power of the second signal is determined based on the path loss corresponding to the second signal.

[0178] In some optional embodiments, in step 102, determining the path loss corresponding to the second signal based on the first signal and the offset information may specifically include:

[0179] Determining an RSRP offset based on filtering offset values ​​corresponding to multiple RSRP offset information included in the offset information;

[0180] A path loss corresponding to the second signal is determined based on the first RSRP and the RSRP offset.

[0181] In some embodiments, after the RSRP offset Δ is obtained through the above filtering RSRP Finally, some examples of calculating the path loss corresponding to the second signal are:

[0182] PL b,f,c (qd )=referenceSignalPower-(higher layer filtered RSRP+Δ RSRP ) or, PL b,f,c (q d )=referenceSignalPower-(higher layer filtered RSRP-Δ RSRP ). Among them, PL b,f,c (q d ) represents the path loss corresponding to the second signal.

[0183] In some optional embodiments, in step 103, determining the path loss corresponding to the first signal based on the first signal specifically includes:

[0184] Step 1031: Determine a first RSRP based on the first signal;

[0185] In some embodiments, the first RSRP is the RSRP obtained by filtering the layer 1 (i.e., physical layer) reference signal received power L1-RSRP. Filtering includes high-level filtering, or a method of filtering multiple measurement quantities using some filter coefficients. For example, to obtain an average value for multiple measurement quantities (or multiple values), the average value can be a linear average value, a weighted average value, or another type of average value. A method of performing high-level filtering on the measurement quantity Mn (replacing Mn with L1-RSRP means filtering L1-RSRP) is as follows: F n =(1-a)*F n-1 +a*M n

[0186] Where M n is the latest measurement result received from the physical layer (e.g., L1-RSRP in the embodiment of the present disclosure), n is an integer greater than or equal to 1; F n is the updated filtered measurement result (eg, high-level filtered RSRP in the embodiment of the present disclosure); F n-1 is the last filtered measurement result, where F0 is set to M1 (i.e., the first measurement result received from the physical layer); for MeasObjectNR (NR measurement object), where k i The filter coefficient for the corresponding measurement quantity of the i-th QuantityConfigNR in quantityConfigNR-List, where i is indicated by quantityConfigIndex in MeasObjectNR; for other measurements, a=1 / 2 (k / 4), where k is the filter coefficient of the corresponding measurement quantity received by quantityConfig (measurement quantity configuration); for the Universal Radio Access Frequency Division Duplex (UTRA-FDD) system, a = 1 / 2 (k / 4) , where k is the filter coefficient of the corresponding measurement quantity received in quantityConfigUTRA-FDD (UTRA-FDD measurement quantity configuration) in QuantityConfig (measurement quantity configuration).

[0187] Replace the measurement quantity Mn with L1-RSRP, then the first RSRP is F obtained based on the above formula n .

[0188] In some embodiments, the first RSRP is the RSRP obtained by performing higher-layer filtering using multiple L1-RSRPs, including the L1-RSRP corresponding to the first signal. In some embodiments, the first RSRP is the higher-layer filtered RSRP obtained by performing higher-layer filtering on the L1-RSRP corresponding to the first signal, which may be represented by higher-layer filtered RSRP. When the first signal is a signal corresponding to a periodic reference signal resource, an L1-RSRP can be obtained for each transmission corresponding to the periodic reference signal resource. In this case, the terminal can determine the higher-layer filtered RSRP, i.e., the first RSRP, based on the higher-layer filtering calculation formula in the above example.

[0189] In some embodiments, the L1-RSRP for a signal is defined as the linear average of the power contributions (in watts) of the resource elements carrying the signal. In some embodiments, the RSRP is expressed in watts. In some embodiments, the RSRP is expressed in dB or dBm.

[0190] Step 1032: Determine a path loss corresponding to the first signal based on the first RSRP and a reference power. The reference power may be indicated by the network device or pre-agreed between the terminal and the network device (e.g., agreed upon through signaling interaction or through a protocol).

[0191] In some embodiments, the path loss corresponding to the first signal is a path loss determined based on the RSRP of the first signal. In some embodiments, the path loss is determined based on the L1-RSRP of the first signal. In some embodiments, the path loss is determined based on the high-layer filtered RSRP of the first signal.

[0192] Use PL b,f,c (q d ) represents the path loss corresponding to the first signal, then one determination method is:

[0193] PL b,f,c (q d )=referenceSignalPower-higher layer filtered RSRP. That is, the path loss corresponding to the first signal is the difference between the reference power and the first RSRP.

[0194] As an example, the UE determines an offset value Δ (path loss offset and / or RSRP offset) based on the offset information, and the path loss corresponding to the first signal is PL bfc (q d ), then the path loss corresponding to the second signal is PL b,f,c (q d )+Δ(Then, when calculating the transmission power of the second signal, PL can be used in the calculation formula for calculating the transmission power of the second signal. b,f,c (q d )+Δ replace the original PL b,f,c (q d )), or, the path loss corresponding to the second signal is PL b,f,c (q d )-Δ(Then, when calculating the transmission power of the second signal, PL can be used in the calculation formula for calculating the transmission power of the second signal. b,f,c (q d )-Δ replaces the original PL b,f,c (q d )).

[0195] In the above embodiments, the path loss corresponding to the second signal may be understood as the path loss used to determine the transmission power of the second signal.

[0196] Determine the path loss PL corresponding to the first signal b,f,c (q d ), the terminal may further determine the transmission power of the second signal based on the transmission power calculation formula of the second signal.

[0197] For example, in the NR system, some path loss PL corresponding to the first signal b,f,c (q d ) An example of determining the transmission power of the second signal is as follows:

[0243] In some embodiments, the offset information includes multiple path loss offset information and / or multiple RSRP offset information.

[0244] In some embodiments, the plurality of path loss offset information corresponds to a second RSRP and / or the plurality of path loss offset information corresponds to the first signal, and the second RSRP is used to determine the first RSRP. In some embodiments, the second RSRP is the L1-RSRP of the first signal, and the first RSRP is an RSRP obtained by filtering the plurality of L1-RSRPs including the second RSRP (e.g., a higher-layer filtered RSRP).

[0245] In some embodiments, the correspondence between the multiple pieces of path loss offset information and the second RSRPs is such that each piece of path loss offset information corresponds to one second RSRP. In some embodiments, the correspondence between the multiple pieces of path loss offset information and the second RSRPs is a one-to-one correspondence. That is, the multiple second RSRPs correspond one-to-one to the multiple pieces of path loss offset information. In this case, the terminal can determine a power adjustment value for each second RSRP based on its corresponding path loss offset value, thereby better determining the transmission power of the second signal.

[0246] In some embodiments, the correspondence between the multiple pieces of path loss offset information and the first signal is such that each piece of path loss offset information corresponds to one first signal. In some embodiments, the correspondence between the multiple pieces of path loss offset information and the first signal is a one-to-one correspondence, i.e., the multiple pieces of path loss offset information have a one-to-one correspondence with multiple first signals. In this case, the terminal can determine a power adjustment value for each first signal based on its corresponding path loss offset value, thereby better determining the transmission power of the second signal.

In some embodiments, the correspondence between the multiple RSRP offset information and the second RSRP is a one-to-one correspondence.

In this case, the terminal can determine an adjusted RSRP value for each second RSRP based on its corresponding RSRP offset information, thereby better determining the transmission power of the second signal.

[0249] In some embodiments, the correspondence between the multiple RSRP offset information and the first signal is such that each RSRP offset information corresponds to one first signal. In some embodiments, the correspondence between the multiple RSRP offset information and the first signal is a one-to-one correspondence, i.e., the multiple RSRP offset information domains have a one-to-one correspondence with multiple first signals. In this case, the terminal can determine an adjusted RSRP value for each first signal based on its corresponding RSRP offset value, thereby better determining the transmission power of the second signal.

[0250] In some embodiments, the number of the path loss offset information is equal to the number of the second RSRPs used to determine the first RSRP. In this case, the network device sends a corresponding path loss offset information for each second RSRP.

[0251] In some embodiments, the amount of path loss offset information is less than the number of second RSRPs used to determine the first RSRP. In this case, the network device only sends the corresponding path loss offset information for some of the second RSRPs, or multiple second RSRPs share the same path loss offset information. This can save the overhead of path loss offset information. For example, if a piece of path loss offset information sent by the network device is applicable for a period of time, during this period, the terminal can determine the higher-layer filtered RSRP (first RSRP) based on multiple second RSRPs, but corresponding to the same path loss offset information.

[0252] In some optional embodiments, in step 103, determining the path loss offset and / or the reference signal received power (RSRP) offset based on the offset information includes at least one of the following:

[0253] 1. The offset information includes multiple path loss offset information, and the path loss offset is determined based on filtering the offset values ​​corresponding to the multiple path loss offset information; and the transmission power of the second signal is determined based on the path loss corresponding to the first signal and the path loss offset.

[0254] 2. The offset information includes multiple RSRP offset information, and the RSRP offset is determined based on filtering the offset values ​​corresponding to the multiple RSRP offset information.

[0255] After obtaining the RSRP offset Δ through the above filtering, the transmission power of the second signal may be determined based on the path loss corresponding to the first signal and the RSRP offset.

[0256] In some embodiments, the filter parameters used when performing high-level filtering on the above-mentioned offset value are configured by the network device for the terminal.

[0257] In some embodiments, the filter parameters used when performing high-layer filtering on the offset value are the same as the parameters used when determining the high-layer filtered RSRP.

[0258] In some embodiments, the first signal includes a reference signal corresponding to the first signal resource.

[0259] Specifically, the first signal resource includes one or more of the following:

[0260] a reference signal resource configured by the network device for the second signal;

[0309] The method for determining the uplink signal transmission power of the embodiment of the present disclosure receives a first signal and offset information sent by a network device; determines the path loss corresponding to the second signal based on the first signal and the offset information, and determines the transmission power of the second signal based on the path loss corresponding to the second signal; or determines the path loss corresponding to the first signal based on the first signal, determines the path loss offset and / or reference signal received power RSRP offset based on the offset information, and determines the transmission power of the second signal based on the path loss corresponding to the first signal, and the path loss offset and / or RSRP offset. In this way, when applied to a multi-TRP scenario, for the uplink transmission of the second signal facing a TRP without downlink transmission, the transmission power of the second signal can be determined based on the offset information and the first signal sent by the network device from other TRPs. In a more general uplink transmission scenario (such as a single TRP scenario or a more general multi-TRP scenario), it is also possible to adjust the uplink transmission power or path loss based on the offset information sent by the network device, thereby obtaining a more accurate uplink transmission power. In some embodiments, when the above embodiments are applied to the determination of the uplink signal transmission power of a TRP with uplink and downlink transmission, the first signal and the second signal are signals corresponding to the same TRP. At this time, the offset information can be used to adjust the uplink transmission power or path loss, so that the terminal can determine a more accurate uplink transmission power or one with better performance.

[0310] As shown in Figure 2, a flow chart of a method for determining uplink signal transmission power provided by an embodiment of the present disclosure is provided. The method is applied to a network device, i.e., executed by a network device such as a base station. The method may include:

[0311] Step 201: Send a first signal to a terminal;

[0312] In some embodiments, the first signal includes a reference signal corresponding to a first signal resource. In some embodiments, the first signal is a reference signal transmitted based on the first signal resource. That is, the first signal is transmitted on the time-frequency domain resources corresponding to the first signal resource. In some embodiments, the first signal includes at least one of the following: an SSB; a CSI-RS. In some embodiments, the first signal resource is a downlink signal resource, including at least one of the following: an SSB resource; a CSI-RS resource.

[0313] In some embodiments, the first signal resource is a periodic signal resource.

[0314] In some embodiments, the first signal resource is a semi-persistent signal resource.

[0315] In some embodiments, the first signal resource is a non-periodic signal resource.

[0316] Step 202: Send offset information to the terminal;

[0317] In some embodiments, the network device sends the offset information to the terminal by at least one of the following:

[0318] RRC signaling;

[0319] MAC-CE signaling;

[0320] DCI signaling.

[0321] In some embodiments, after the network device configures the offset information through RRC signaling, it may update the offset information through MAC-CE signaling and / or DCI signaling.

[0322] In some embodiments, the offset information includes path loss offset information and / or RSRP offset information, wherein the path loss offset information is used to indicate / determine the path loss offset, and the RSRP offset information is used to indicate / determine the RSRP offset. Then, the terminal may determine the path loss offset and / or RSRP offset based on the offset information.

[0323] In some embodiments, the path loss offset is an offset between a path loss corresponding to the second signal and a path loss corresponding to the first signal.

[0324] In some embodiments, the RSRP offset includes one or more of the following:

[0325] an offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP, where the first TRP is the TRP corresponding to the first signal and the second TRP is the TRP corresponding to the second signal;

[0326] An offset between the RSRP corresponding to the second control resource pool index and the RSRP corresponding to the first control resource pool index, wherein the first control resource pool index is the control resource pool index corresponding to the first signal, and the second control resource pool index is the control resource pool index corresponding to the second signal;

[0327] an offset between an RSRP corresponding to a second TCI state and an RSRP corresponding to a first TCI state, where the first TCI state is the TCI state corresponding to the first signal and the second TCI state is the TCI state corresponding to the second signal;

[0328] an offset between an RSRP corresponding to a second cell and an RSRP corresponding to a first cell, where the first cell is the cell corresponding to the first signal and the second cell is the cell corresponding to the second signal;

[0329] an offset between an RSRP corresponding to a second SRS resource set and an RSRP corresponding to a first SRS resource set, where the first SRS resource set is an SRS resource set corresponding to the first signal and the second SRS resource set is an SRS resource set corresponding to the second signal;

[0330] an offset between an RSRP corresponding to a second carrier and an RSRP corresponding to a first carrier, where the first carrier is a carrier corresponding to the first signal and the second carrier is a carrier corresponding to the second signal;

[0331] The offset between the RSRP corresponding to the second beam and the RSRP corresponding to the first beam, where the first beam is the beam corresponding to the first signal, and the second beam is the beam corresponding to the second signal.

[0332] The network device may transmit the first signal and the offset information to the terminal in any order. For example, the network device transmits the first signal and the offset information to the terminal at the same time. For another example, the network device transmits the offset information after transmitting the first signal to the terminal. For another example, the network device transmits the first signal after transmitting the offset information to the terminal. For another example, the network device transmits the offset information after transmitting the offset information to the terminal. For another example, the first signal includes multiple signals, the offset information indicates an offset, the network device transmits the offset information after transmitting some first signals, and then continues to transmit the first signal. For another example, the first signal includes multiple signals, the offset information also includes multiple signals, and the network device transmits the first signal and the offset information alternately. For example, the network device transmits some offset information after transmitting some first signals, and then continues to transmit the first signal, and then continues to transmit the offset information. For another example, the network device transmits one offset information each time it transmits a first signal.

[0333] In some embodiments, the offset information is determined by the network device, for example, based on transmission of an uplink signal.

[0334] Step 203: Receive a second signal sent by the terminal;

[0335] Wherein, the second signal is an uplink signal. In some embodiments, the second signal includes at least one of the following: PUSCH, PUCCH), PRACH, SRS, DMRS.

[0336] The first signal and the offset information are used to determine the path loss corresponding to the second signal, and the path loss corresponding to the second signal is used to determine the transmission power of the second signal; that is, the transmission power of the second signal is determined by the terminal based on the first signal and the offset information to determine the path loss corresponding to the second signal, and based on the path loss corresponding to the second signal.

[0337] Alternatively, the first signal is used to determine the path loss corresponding to the first signal, and the offset information is used to determine a path loss offset and / or a reference signal received power (RSRP) offset; the path loss corresponding to the first signal, and the path loss offset and / or RSRP offset are used to determine the transmission power of the second signal. That is, the transmission power of the second signal is determined by the terminal based on the first signal to determine the path loss corresponding to the first signal, based on the offset information to determine the path loss offset and / or reference signal received power (RSRP) offset; and is further determined based on the path loss corresponding to the first signal, and the path loss offset and / or RSRP offset.

[0338] Among them, the optional implementation method of determining the transmission power of the second signal has been explained on the terminal side and will not be repeated here.

[0339] Specifically, the receiving terminal sends the second signal using the determined transmission power of the second signal.

[0340] In some embodiments, the network device includes multiple TRPs, wherein the multiple TRPs include a UL Rx only TRP and other TRPs (i.e., a TRP that can be used for both uplink and downlink transmission). In this way, when the application scenario of the embodiment of the present disclosure is a UL Rx only TRP scenario, the other TRPs in the network device will send a first signal to the terminal, that is, the first signal is not a signal from the UL Rx only TRP, but a signal from other TRPs with downlink signal transmission. In this way, it is convenient for the terminal side to calculate the path loss based on the downlink signal transmitted by other TRPs, and then determine the transmission power of the uplink signal. Of course, the method of the embodiment of the present disclosure is not only applicable to scenarios with UL Rx only TRP configured, but also to general scenarios for transmitting uplink signals (such as single TRP scenarios or multiple TRP scenarios, and the multiple TRP scenarios can be scenarios including UL Rx only TRP or scenarios not including UL Rx only TRP). For general scenarios for transmitting uplink signals, the transmission power of the uplink signal can also be determined by using the method provided by the embodiment of the present disclosure.

[0341] In some embodiments, the first signal and the second signal have at least one of the following relationships:

[0342] The first signal and the second signal correspond to different control resource set pool indexes;

[0343] The first signal and the second signal correspond to different transmission reception points TRP;

[0344] The first signal and the second signal correspond to different transmission control information TCI states;

[0345] The first signal and the second signal correspond to different sounding reference signal SRS resource sets;

[0346] The first signal and the second signal correspond to different cells;

[0347] The first signal and the second signal correspond to different carriers.

[0348] When the first signal and the second signal correspond to different TRPs, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP. Determining the path loss corresponding to the second signal based on the first signal and the offset information can achieve the determination of the path loss of the uplink signal of another TRP based on the downlink signal of one TRP, and then determine the transmission power of the uplink signal. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the path loss of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission, and then determine the transmission power of the uplink signal. Determining the path loss corresponding to the first signal based on the first signal, determining the path loss offset and / or reference signal received power RSRP offset based on the offset information, and determining the transmission power of the second signal based on the path loss corresponding to the first signal and the path loss offset and / or RSRP offset can achieve the determination of the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, the terminal can calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0349] The signals corresponding to different control resource set pools may correspond to different transmission antennas, different beams, different TRPs, etc. When the first signal and the second signal correspond to different control resource set pools (i.e., different CORESETPoolIndex), the first signal is a downlink signal corresponding to one / a group of transmission antennas / beams / TRPs, and the second signal is an uplink signal corresponding to another / a group of transmission antennas / beams / TRPs. Based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to another / a group of transmission antennas / beams / TRPs based on the downlink signal of one / a group of transmission antennas / beams / TRPs. In particular, in a multi-TRP scenario, different TRPs can be configured with different control resource set pool indexes CORESETPoolIndex. When the first signal and the second signal correspond to different CORESETPoolIndex, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP. Based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, the terminal can calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0350] When the first signal and the second signal correspond to different TCI states, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to another TCI state based on the downlink signal corresponding to one TCI state. In some embodiments, different TCI states correspond to different beams and / or TRPs, etc. In particular, in a multi-TRP scenario, when different TRPs can be configured as different TCI states, and the first signal and the second signal correspond to different TCI states, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP, then based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0351] When the first signal and the second signal correspond to different SRS resource sets, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to another SRS resource set based on the downlink signal corresponding to one SRS resource set. In particular, different SRS resource sets can correspond to different beams and / or TRPs, etc. In particular, in a multi-TRP scenario, when different TRPs are configured to correspond to different SRS resource sets, when the first signal and the second signal correspond to different SRS resource sets, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0352] When the first signal and the second signal correspond to different cells, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to one cell based on the downlink signal corresponding to another cell. In particular, in a multi-TRP scenario, different TRPs can be configured as different cells. Then, when the first signal and the second signal correspond to different cells, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP. Based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, the terminal can calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0353] When the first signal and the second signal correspond to different carriers, based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal corresponding to one carrier based on the downlink signal corresponding to another carrier. In particular, in a multi-TRP scenario, different TRPs can be configured as different carriers. When the first signal and the second signal correspond to different carriers, the first signal is a downlink signal from one TRP, and the second signal is an uplink signal sent to another TRP, then based on the method of this embodiment, the terminal can determine the transmission power of the uplink signal of another TRP based on the downlink signal of one TRP. In a multi-TRP scenario including a UL Rx only TRP, it can be used for the terminal to calculate the transmission power of the uplink signal sent to the UL Rx only TRP based on the downlink signal sent by the network device from a TRP with DL transmission.

[0354] In some embodiments, the offset information includes path loss offset information and / or RSRP offset information, wherein the path loss offset information is used to indicate / determine the path loss offset, and the RSRP offset information is used to indicate / determine the RSRP offset. Then, the terminal may determine the path loss offset and / or RSRP offset based on the offset information.

[0355] In some embodiments, the path loss offset is an offset between a path loss corresponding to the second signal and a path loss corresponding to the first signal.

[0356] In some embodiments, the offset between the path loss corresponding to the second signal and the path loss corresponding to the first signal is the offset of the path loss corresponding to the second signal (i.e., the path loss used to determine the transmission power of the second signal) relative to the path loss corresponding to the first signal (i.e., the path loss determined based on the first signal). In some embodiments, the offset between the path loss corresponding to the second signal and the path loss corresponding to the first signal is the offset of the path loss corresponding to the first signal relative to the path loss corresponding to the second signal.

[0357] In some embodiments, the offset between the path loss corresponding to the second signal and the path loss corresponding to the first signal is the difference between the path loss corresponding to the second signal and the path loss corresponding to the first signal. The difference can be a linear value or a dB value. In some embodiments, the offset between the path loss corresponding to the second signal and the path loss corresponding to the first signal is the ratio between the path loss corresponding to the second signal and the path loss corresponding to the first signal. The ratio can be a linear value or a dB value.

[0358] In some embodiments, the RSRP offset includes one or more of the following:

[0359] an offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP, where the first TRP is the TRP corresponding to the first signal and the second TRP is the TRP corresponding to the second signal;

[0360] An offset between the RSRP corresponding to the second control resource pool index and the RSRP corresponding to the first control resource pool index, wherein the first control resource pool index is the control resource pool index corresponding to the first signal, and the second control resource pool index is the control resource pool index corresponding to the second signal;

[0361] an offset between an RSRP corresponding to a second TCI state and an RSRP corresponding to a first TCI state, where the first TCI state is the TCI state corresponding to the first signal and the second TCI state is the TCI state corresponding to the second signal;

[0362] an offset between an RSRP corresponding to a second cell and an RSRP corresponding to a first cell, where the first cell is the cell corresponding to the first signal and the second cell is the cell corresponding to the second signal;

[0363] an offset between an RSRP corresponding to a second SRS resource set and an RSRP corresponding to a first SRS resource set, where the first SRS resource set is an SRS resource set corresponding to the first signal, and the second SRS resource set is an SRS resource set corresponding to the second signal;

[0364] an offset between an RSRP corresponding to a second carrier and an RSRP corresponding to a first carrier, where the first carrier is a carrier corresponding to the first signal and the second carrier is a carrier corresponding to the second signal;

[0365] The offset between the RSRP corresponding to the second beam and the RSRP corresponding to the first beam, where the first beam is the beam corresponding to the first signal, and the second beam is the beam corresponding to the second signal.

[0366] In some embodiments, the offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP is the offset of the RSRP corresponding to the second TRP relative to the RSRP corresponding to the first TRP. In some embodiments, the offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP is the offset of the RSRP corresponding to the first TRP relative to the RSRP corresponding to the second TRP.

[0367] In some embodiments, the offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP is the difference between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP. The difference may be a linear value or a dB value. In some embodiments, the offset between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP is the ratio between the RSRP corresponding to the second TRP and the RSRP corresponding to the first TRP.

[0389] In some embodiments, the correspondence between the multiple pieces of path loss offset information and the second RSRPs is such that each piece of path loss offset information corresponds to one second RSRP. In some embodiments, the correspondence between the multiple pieces of path loss offset information and the second RSRPs is a one-to-one correspondence. That is, the multiple second RSRPs correspond one-to-one to the multiple pieces of path loss offset information. In this case, the terminal can determine a power adjustment value for each second RSRP based on its corresponding path loss offset value, thereby better determining the transmission power of the second signal.

[0390] In some embodiments, the correspondence between the multiple pieces of path loss offset information and the first signal is such that each piece of path loss offset information corresponds to one first signal. In some embodiments, the correspondence between the multiple pieces of path loss offset information and the first signal is a one-to-one correspondence, i.e., the multiple pieces of path loss offset information have a one-to-one correspondence with multiple first signals.

[0395] In some embodiments, the amount of path loss offset information is less than the number of second RSRPs used to determine the first RSRP. In this case, the network device only sends the corresponding path loss offset information for some of the second RSRPs, or multiple second RSRPs share the same path loss offset information. This can save the overhead of path loss offset information. For example, if a piece of path loss offset information sent by the network device is applicable for a period of time, during this period, the terminal can determine the higher-layer filtered RSRP (first RSRP) based on multiple second RSRPs, but corresponding to the same path loss offset information.
