[0125] At present, for uplink transmission, in order to meet the scheduling requirements of the network, it is necessary to report a Power Headroom Report (PHR). PHR reflects the available power of the terminal, that is, the power headroom. PHR includes multiple types, for example, Type 1 PHR is mainly related to the Physical Uplink Shared Channel, while Type 3 PHR is mainly related to the Sounding Reference Signal (SRS).

[0126] The content reported in the PHR includes:

[0127] The maximum power that can be transmitted in each cell;

[0128] The power headroom (PH) after the UE sends an uplink control channel (such as a physical uplink control channel (PUCCH)) in each cell.

[0129] The power headroom after the UE sends an uplink data channel (such as PUSCH) in each cell.

[0130] The power headroom after the UE sends an uplink sounding channel (such as SRS) in each cell.

[0131] If the UE has a real physical channel to send, the power headroom after the real sending of the physical channel is reported. If the UE does not have a real physical channel to send, the power headroom after the reference (or virtual) sending of the physical channel is reported.

[0132] In the communication system, communication scenarios of single transmission point (single transmission and receiving point, S-TRP) and multiple transmission points (transmission and receiving point, TRP) are supported. The multiple transmission points (transmission and receiving point, TRP) include deployment scenarios of downlink single transmission point (single transmission and receiving point, S-TRP) and uplink multiple transmission points (multi transmission and receiving point, M-TRP), which can also be called an asymmetric M-TRP scenario. That is, asymmetric M-TRP transmission is achieved by deploying heterogeneous networks to improve uplink coverage and throughput. The heterogeneous network, for example, includes a main next generation NodeB (next generation NodeB, gNB) and a micro node used only for uplink transmission, wherein the micro node used only for uplink transmission can be called a TRP used only for uplink transmission (uplink only TRP, UL only TRP). The main gBN used for uplink and downlink transmission can also be called a downlink TRP (downlink TRP, DL TRP)

[0133] For ease of understanding, the present disclosure introduces the following concepts.

[0134] 1) M-TRP transmission: In order to improve the coverage at the edge of the cell and provide a more balanced service quality in the service area, multi-point collaboration is still an important technical means in the new radio (NR) system. From the perspective of network morphology, network deployment with a large number of distributed access points + baseband centralized processing will be more conducive to providing a balanced user experience rate and significantly reduce the delay and signaling overhead caused by handover. With the increase of frequency bands, relatively dense access point deployment is also required from the perspective of ensuring network coverage. In high frequency bands, with the improvement of the integration of active antenna equipment, modular active antenna arrays will be more inclined to be adopted. The antenna array of each TRP can be divided into several relatively independent antenna panels, so the shape and number of ports of the entire array can be flexibly adjusted according to the deployment scenario and business needs. The antenna panels or TRPs can also be connected by optical fiber for more flexible distributed deployment. In the millimeter wave band, as the wavelength decreases, the blocking effect caused by obstacles such as human bodies or vehicles will be more significant. In this case, from the perspective of ensuring the robustness of the link connection, it is also possible to utilize the collaboration between multiple TRPs or panels to transmit / receive from multiple beams at multiple angles, thereby reducing the adverse effects of the blocking effect.

[0135] According to the mapping relationship between the transmitted signal stream and multiple TRPs / panels, multi-point cooperative transmission technology can be divided into coherent and incoherent transmission. In coherent transmission, each data layer is mapped to multiple TRPs / panels through a weighted vector. In incoherent transmission, each data stream is only mapped to part of the TRP / panel. Coherent transmission has higher requirements for the synchronization between transmission points and the transmission capacity of the backhaul link, and is therefore more sensitive to many non-ideal factors in real deployment conditions. Relatively speaking, incoherent transmission is less affected by the above factors, so it is the key consideration for multi-point transmission technology.

[0136] For the uplink, the physical uplink shared channel (PUSCH) for different TRPs may actually pass through channels with very different spatial characteristics. Therefore, it is considered that the quasi co-location type D (QCL-D) of PUSCH in different transmission directions is different.

[0137] 2) Transmission configuration indicator state (TCIstate) indication: The downlink TCI state or joint TCI state indicated by the standard UE is used to determine the downlink transmission beam, and the indicated uplink TCI state or joint TCI state is used to determine the uplink beam. Here, the downlink beam refers to the user-specific physical downlink shared channel (physical downlink shared channel, PDSCH) and all / part of the PDCCH beam in a control channel (control channel, CC). The uplink beam refers to the uplink transmit spatial filter based on the dynamically authorized / configurable PUSCH and all or part of the dedicated PUCCH resources of a CC.

[0138] A TCI state pool is used for the downlink TCI state and joint TCI state in independent beam indication.

[0139] For the case of joint beam indication, the TCI field only needs to indicate one joint TCI state, which is used to determine both the uplink and downlink transmission beams. However, for the case of independent beam indication, the downlink transmission beam and the uplink transmission beam are no longer the same and need to be indicated separately. In addition, there are three scenarios: it is necessary to indicate both the downlink transmission beam and the uplink transmission beam to the user at the same time, it is only necessary to indicate the downlink transmission beam to the user, or it is only necessary to indicate the uplink transmission beam to the user. For this reason, it is stipulated that in the case of independent beam indication, the mapping relationship between the TCI field and the TCI state in DCI formats 1_1 / 1_2 is as follows:

[0140] One code point in the TCI field can correspond to both a downlink TCI state and an uplink TCI state;

[0141] One code point in the TCI field corresponds to only one downlink TCI state. At this time, the user keeps the current UL TCI state unchanged.

[0142] One code point in the TCI field corresponds to only one uplink TCI state, and the user keeps the current DL TCI state unchanged.

[0143] Currently, the defined TCI state indication method has been expanded. The uplink and downlink TCI state information corresponding to up to two collaborative TRPs can be indicated simultaneously through the TCI state code point in the DCI.

[0144] 3) For reporting of type 3 PHR:

[0145] Currently, the following methods are supported for UL only TRP path loss estimation in asymmetric M-TRP scenarios:

[0146] (1) Perform downlink path loss estimation based on the downlink path loss reference signal (DL PL RS), and obtain the path loss estimation value of the UL only TRP through the path loss offset value associated with the transmission configuration indicator state (TCI state) of the UL only TRP, and use it for uplink channel or signal transmission. That is, PL_UL = PL_DL-PL_offset. Among them, PL_UL is the path loss estimation value of the UL only TRP, PL_DL is the path loss estimation value of the DL TRP, and PL_offset is the path loss offset value associated with the TCI state of the UL only TRP.

[0147] (2) Calculate PL_UL through (1). By sending SRS to the UL only TRP, the change PL_offset' relative to PL_UL is updated, PL_UL'=PL_UL+ / -PL_offset'.

[0148] On the one hand, (1) can be used to estimate the path loss of UL only TRP. When the transmission power of SRS sent to different TRPs in frequency band (Frequency Range, FR) 2 is different, the network device needs to know the SRS transmission power or the difference in transmission power. The transmission power corresponding to different SRS resources / SRS resource sets can be reported through type 3 PHR.

[0149] On the other hand, if the DL TRP cannot effectively receive the transmitted SRS signal, there will be problems in estimating the path loss of the ULonly TRP through (1). In this case, (2) should be used first. The transmit power corresponding to the SRS resource / SRS resource set of the corresponding TRP can also be reported through the type 3 PHR, or the SRS transmit power can be adjusted according to the PHR reported by the terminal for the calculation of (1) (applicable to FR1&FR2).

[0150] The type 3 PHR reported by the terminal can be used to estimate the path loss information of different TRP nodes sent through SRS, as well as the transmission power control (TPC) decision of SRS.

[0151] In addition, the terminal needs to send SRS for antenna switching (Antenna Switching, AS) to the DL TRP, and the sending of SRS also needs to support reporting type 3 PHR.

[0152] Therefore, the present disclosure provides a communication method, in which a PHR is sent to a network device through a terminal, and the PHR includes at least one of type 1 and type 3, so that when the terminal has the ability to send type 1 PHR and type 3 PHR on the same carrier, at least one of type 1 PHR and type 3 PHR can be reported more flexibly, thereby improving communication efficiency.

[0164] Figure 2 FIG. 1 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. Figure 2 As shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The method includes:

[0165] Step S2101: Terminal 101 determines that the PHR includes at least one of Type 1 PHR and Type 3 PHR.

[0166] In some embodiments, the terminal may determine that the PHR includes at least one of a Type 1 PHR and a Type 3 PHR.

[0167] Optionally, the terminal may determine that the PHR includes a Type 1 PHR. For example, if the terminal is configured to report a single PHR, the terminal may determine that the PHR includes a Type 1 PHR.

[0168] Optionally, the terminal may determine that the PHR includes a type 3 PHR. For example, if the terminal is configured to report a single PHR, the terminal may determine that the PHR includes a type 3 PHR.

[0169] Optionally, the terminal may determine that the PHR includes a type 1 PHR and a type 3 PHR. For example, if the terminal is configured to report multiple PHRs, the terminal may determine that the PHR includes a type 1 PHR and a type 3 PHR.

[0170] It can be understood that in the present disclosure, the terminal is configured to report a single PHR, which means that the network device instructs the terminal to report only one type of PHR. The present disclosure does not limit the description method. For example, it can also be described as the terminal being configured to report a single type of PHR. Correspondingly, the terminal is configured to report multiple PHRs, which means that the network device instructs the terminal to report multiple types of PHRs. The same type of PHR may include the reporting amount of one or more cells, or may include the reporting amount of one or more carriers, or may include the reporting amount of one or more TRPs. Among them, the reporting amount includes but is not limited to the PH value and the maximum transmit power (Pcmax).

[0171] In some embodiments, the terminal 101 has the capability to send type 1 PHR and type 3 PHR on the same carrier. Type 1 PHR corresponds to the transmission of PUSCH. Type 3 PHR corresponds to the transmission of SRS. For example, when the terminal has the capability to send type 1 PHR and type 3 PHR on the same carrier, the terminal may determine that the PHR includes at least one of type 1 PHR and type 3 PHR.

[0172] In some embodiments, SRS supports up to 2 closed-loop power control (CLPC) states. The closed-loop power adjustment state is included in the power adjustment parameter, and different closed-loop power control adjustment states point to different power adjustment parameters. For example, in an asymmetric M-TRP scenario, the power adjustment parameter for the terminal to send SRS to the UL only TRP is different from the power adjustment parameter for sending SRS to the DL TRP, then SRS can support 2 closed-loop power adjustment states, and different closed-loop power adjustment states can correspond to different TRPs. For example, when the terminal has the ability to send type 1 PHR and type 3 PHR on the same carrier, and SRS supports up to 2 closed-loop power control adjustment states, the terminal can determine that the PHR includes at least one of type 1 PHR and type 3 PHR.

[0173] In some embodiments, the carrier of the serving cell of the terminal is configured with a transmitted PUSCH. For example, when the terminal has the ability to transmit type 1 PHR and type 3 PHR on the same carrier, and the SRS supports up to 2 closed-loop power control adjustment states, and the carrier of the serving cell of the terminal is configured with a transmitted PUSCH, the terminal may determine that the PHR includes at least one of type 1 PHR and type 3 PHR.

[0174] In some embodiments, if the terminal is configured to report a single PHR, the terminal determines that the PHR includes one of a type 1 PHR or a type 3 PHR.

[0175] Optionally, if Type 1 PHR is determined based on actual PUSCH transmission, Type 1 PHR is included in PHR. For example, if Type 1 PHR is determined based on actual PUSCH transmission, then it is not necessary to consider whether Type 3 PHR is determined based on actual SRS transmission or based on reference SRS transmission configuration, and Type 1 PHR can be directly included in PHR. It is understandable that if Type 1 PHR is determined based on actual PUSCH transmission, then the PH value in Type 1 PHR is the actual PH value, and the actual PH value is relatively reliable, so Type 3 PHR can be ignored. Due to the real-time, accuracy, and compatibility of Type 1 PHR, Type 1 PHR is reported to improve communication efficiency.

[0176] Optionally, if type 1 PHR is determined based on actual PUSCH transmission, and type 3 PHR is determined based on actual SRS transmission, then type 1 PHR is included in the PHR. Wherein, type 1 PHR is determined based on actual PUSCH transmission, which can be understood as the presence of actual PUSCH transmission in the time unit of reporting PHR, and the terminal can determine the PH value in type 1 PHR based on the measurement of the PUSCH actually transmitted. Correspondingly, type 3 PHR is determined based on actual SRS transmission, which can be understood as the presence of actual SRS transmission in the time unit of reporting PHR, and the terminal can determine the PH value in type 3 PHR based on the measurement of the SRS actually transmitted. It can be understood that when both type 1 PHR and type 3 PHR are determined based on actual transmission, the PH values ​​contained in type 1 PHR and type 3 PHR are actual PH values. Then, due to the real-time, accuracy, and compatibility of type 1 PHR, it can be selected to report type 1 PHR first to improve communication efficiency. Wherein, the time unit can be a time slot, but is not limited to this.

[0177] Optionally, if type 1 PHR is determined based on a reference PUSCH transmission configuration, and type 3 PHR is determined based on a reference SRS transmission configuration, then the PHR includes type 1 PHR. Wherein, type 1 is determined based on a reference PUSCH transmission configuration, which can be understood as no actual PUSCH transmission in the time unit for reporting PHR, but type 1 PHR needs to be reported, so the reference PUSCH transmission configuration can be measured to determine a virtual PH value. Wherein, the reference PUSCH transmission configuration can also be referred to as a virtual PUSCH transmission configuration, and the reference PUSCH transmission configuration can be preconfigured by a network device. The network device can preconfigure one or more sets of reference PUSCH transmission configurations. Accordingly, type 3 PHR is determined based on a reference SRS transmission configuration, which can be understood as no actual SRS transmission in the time unit for reporting PHR, but type 3 PHR needs to be reported, so the reference SRS transmission configuration can be measured to determine a virtual PH value. Wherein, the reference SRS transmission configuration can also be referred to as a virtual SRS transmission configuration, and the reference SRS transmission configuration can be preconfigured by a network device. The network device may preconfigure one or more reference SRS transmission configurations. It is understood that when both Type 1 PHR and Type 3 PHR are determined based on the reference transmission configuration, the PH values ​​contained in Type 1 PHR and Type 3 PHR are virtual PH values. Then, due to the real-time, accuracy, and compatibility of Type 1 PHR, Type 1 PHR may be reported preferentially to improve communication efficiency. The time unit may be a time slot, but is not limited thereto.

[0178] Optionally, if type 1 PHR is determined based on actual PUSCH transmission, type 3 is determined based on reference SRS transmission configuration, and PHR includes type 1 PHR. It can be understood that when type 3 PHR includes a virtual PH value and type 1 PHR includes an actual PH value, when the terminal is configured to report a single PHR, the PHR including the actual PH value is selected to be reported to improve the reliability of the PHR.

[0179] Optionally, if type 1 PHR is determined based on a reference PUSCH transmission configuration and type 3 is determined based on actual SRS transmission, the PHR includes type 3 PHR. It can be understood that when type 3 PHR includes a virtual PH value and type 1 PHR includes an actual PH value, when the terminal is configured to report a single PHR, the PHR including the actual PH value is selected to be reported to improve the reliability of the PHR.

[0180] In some embodiments, when the terminal has at least two actual SRS transmissions, the terminal may select one from the at least two actual SRS transmissions according to the first priority rule, and determine the PH value included in the type 3 PHR based on the selected SRS transmission. The existence of two actual SRS transmissions may be understood as the existence of at least two actual SRS transmissions in the time unit of reporting the PHR.

[0181] In some embodiments, the first priority rule includes at least one of the following: giving priority to SRS transmission whose configuration function corresponding to the first TRP is beam management, and the first TRP is used for uplink transmission; giving priority to SRS transmission whose configuration function corresponding to the first TCI state is beam management, and the first TCI state is used for uplink transmission; giving priority to SRS transmission whose configuration function corresponding to the second TRP is beam management, and the second TRP is used for both uplink and downlink transmissions; giving priority to SRS transmission whose configuration function corresponding to the second TCI state is beam management, and the second TCI state is used for both uplink and downlink transmissions; giving priority to SRS transmission whose function is antenna switching; giving priority to SRS transmission with an earlier start transmission time; SRS transmission whose function is codebook transmission has the lowest priority; SRS transmission whose function is non-codebook transmission has the lowest priority.

[0182] Optionally, the first priority rule includes giving priority to SRS transmission whose configuration function corresponding to the first TRP is beam management, and the first TRP is used for uplink transmission. For example, when there are at least two SRS transmissions corresponding to different functions, they correspond to different TRPs. The SRS transmission whose function is beam management (BM) and corresponds to the first TRP can be given priority to determine the PH value contained in the type 3 PHR. For example, SRS supports 2 closed-loop power adjustment states, the closed-loop power adjustment state of the SRS transmission corresponding to the first TRP is i0, and the closed-loop power adjustment state of the second TRP is i1. Then the SRS transmission with a closed-loop power adjustment state of i0 can be given priority to determine the type 3 PHR. Among them, i0 and i1 are the indexes of the closed-loop power adjustment states, which can also be called the identifiers of the closed-loop power adjustment states. Among them, the first TRP is used for uplink transmission, for example, the first TRP can be the UL only TRP in the asymmetric M-TRP, which can also be called a micro node. The second TRP is used for both uplink and downlink transmissions. For example, the second TRP can be the primary gNB in ​​an asymmetric M-TRP scenario, which can also be called DL TRP.

[0183] Optionally, the first priority rule includes giving priority to SRS transmission whose configuration function corresponding to the first TCI state is beam management. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, and the SRS does not support two closed-loop power adjustment states, the SRS transmission corresponding to the first TCI state can be given priority. Among them, when the SRS does not support two closed-loop power adjustment states, for example, only supports one closed-loop power adjustment state, the SRS transmission sent by the terminal to the first TRP and the SRS transmission sent to the second TRP correspond to the same closed-loop power adjustment state, then the terminal cannot select the SRS transmission corresponding to the first TRP according to the closed-loop power adjustment state. The first TRP and the second TRP can correspond to different TCI states. For example, if the first TRP corresponds to the first TCI state, the SRS transmission sent to the first TRP corresponds to the first TCI state, and the SRS transmission corresponding to the first TRP can be determined by selecting the SRS transmission corresponding to the first TRP.

[0184] Optionally, the first priority rule includes giving priority to SRS transmission whose configuration function corresponding to the second TRP is beam management, and the second TRP is used for both uplink transmission and downlink transmission. For example, when there are at least two SRS transmissions corresponding to different functions, they correspond to different TRPs. The SRS transmission whose function is beam management and corresponds to the second TRP can be preferentially selected to determine the PH value included in the type 3 PHR.

[0185] Optionally, the first priority rule includes giving priority to SRS transmission whose configuration function corresponding to the second TCI state is beam management, and the second TCI state is used for both uplink transmission and downlink transmission. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, and SRS does not support 2 closed-loop power adjustment states, SRS transmission whose function is beam management and corresponds to the second TCI state can be given priority. The second TCI state is used for uplink transmission, for example, the second TCI state can be the TCI state of the second TRP.

[0186] Optionally, the first priority rule includes giving priority to SRS transmissions whose function is antenna switching. For example, when at least two SRS transmissions exist corresponding to different functions, SRS transmissions whose function is antenna switching may be given priority.

[0187] Optionally, the first priority rule includes giving priority to SRS transmissions with earlier start transmission times. For example, if there are at least two actual SRS transmissions in the time unit for reporting the PHR, then SRS transmissions with earlier start transmission times may be given priority.

[0188] Optionally, the first priority rule includes giving priority to SRS transmissions with a later start transmission time. For example, if there are at least two actual SRS transmissions in the time unit for reporting the PHR, then SRS transmissions with a later start transmission time may be given priority.

[0189] Optionally, the first priority rule includes that the SRS transmission function of codebook transmission has the lowest priority. For example, if there are at least two SRS transmissions corresponding to different functions, the SRS transmission function of codebook transmission has the lowest priority, that is, if there are SRS transmissions with multiple functions, the SRS transmission function of codebook is selected only when other selections fail.

[0190] Optionally, the first priority rule includes that the SRS transmission function of non-codebook transmission has the lowest priority. For example, if there are at least two SRS transmissions corresponding to different functions, the SRS transmission function of non-codebook transmission has the lowest priority, that is, if there are SRS transmissions with multiple functions, the SRS transmission function of non-codebook transmission is selected only when other selections fail.

[0191] It is understandable that the above-mentioned first priority rule can be used in combination. For example, when there are at least two actual SRS transmissions including an SRS transmission with the function of beam management, an SRS transmission with the function of antenna switching, and an SRS transmission with the function of codebook or non-codebook transmission, the priority order is: SRS transmission with the function of beam management > SRS transmission with the function of antenna switching > SRS transmission with the function of codebook or non-codebook transmission. Among them, ">" here means that the SRS transmission before the ">" has a higher priority than the SRS transmission after the ">". For another example, when there are at least two actual SRS transmissions including an SRS transmission with the function of beam management corresponding to the first TRP, an SRS transmission with the function of beam management corresponding to the second TRP, an SRS transmission with the function of antenna switching, and an SRS transmission with the function of codebook or non-codebook transmission, the priority order is: SRS transmission with the function of beam management and corresponding to the first TRP>SRS transmission with the function of beam management and corresponding to the second TRP>SRS transmission with the function of antenna switching>SRS transmission with the function of codebook or non-codebook transmission. For another example, when there are at least two actual SRS transmissions including an SRS transmission with the function of antenna switching, and an SRS transmission with the function of codebook or non-codebook transmission, the priority order is: SRS transmission with the function of antenna switching>SRS transmission with the function of codebook or non-codebook transmission. The present disclosure does not give examples one by one, but various combinations are not limited to this.

[0192] In some embodiments, if the terminal is configured to report multiple PHRs, the terminal determines that the PHR includes a type 1 PHR and a type 3 PHR.

[0193] Step S2102: Terminal 101 determines the reporting amount in the PHR.

[0194] In some embodiments, if the terminal is configured to report a single PHR, and the terminal determines that the PHR includes a type 1 PHR, the reported amount in the PHR includes a PH value and a maximum transmit power corresponding to the type 1 PHR. If the type 1 PHR is determined based on actual PUSCH transmission, the PH value corresponding to the type 1 PHR is an actual PH value, and if the type 1 PHR is determined based on a reference PUSCH transmission configuration, the PH value corresponding to the type 1 PHR is a virtual PH value. The terminal can also indicate in the PHR whether the reported PH value is an actual PH value or a virtual PH value through indication information.

[0195] In some embodiments, it is configured as a single PHR report, and the terminal determines that the PHR includes a type 3 PHR, then the reported amount in the PHR includes the PH value and the maximum transmit power corresponding to the type 3 PHR. If the type 3 PHR is determined based on the actual SRS transmission, the PH value corresponding to the type 3 PHR is the actual PH value, and if the type 1 PHR is determined based on the reference SRS transmission configuration, the PH value corresponding to the type 3 PHR is a virtual PH value. The terminal can also indicate in the PHR whether the reported PH value is an actual PH value or a virtual PH value through indication information.

[0196] In some embodiments, if the terminal is configured to report multiple PHRs, the terminal determines that the PHR includes type 1 PHR and type 3 PHR. The reporting amount in the PHR includes the maximum transmit power of the PH value corresponding to the type 1 PHR, and the PH value and maximum transmit power corresponding to the type 3 PHR. Or, the reporting amount in the PHR includes the PH value corresponding to the type 1 PHR and the PH value corresponding to the type 3 PHR, and the total maximum transmit power of the terminal.

[0197] Optionally, the reported amount in the PHR may include the PH value corresponding to the type 1 PHR, the maximum transmit power corresponding to the type 1 PHR, the PH value corresponding to the type 3 PHR, and the maximum transmit power corresponding to the type 3 PHR. That is, both the type 1 PHR and the type 3 PHR may report the corresponding maximum transmit power.

[0198] Optionally, the reported amount in the PHR may include the PH value corresponding to the type 1 PHR, the PH value corresponding to the type 3 PHR, and the total maximum transmit power of the terminal. That is, the type 1 PHR and the type 3 PHR may report a total maximum transmit power.

[0199] In some embodiments, if the terminal is configured to report multiple PHRs, type 1 PHR can be determined based on actual PUSCH transmission or reference PUSCH transmission configuration. Type 3 PHR can be determined based on actual SRS transmission or reference SRS transmission configuration.

[0200] Optionally, type 1 PHR is determined based on actual PUSCH transmission, and type 3 PHR is determined based on actual PUSCH transmission, then the PH value corresponding to type 1 PHR and the PH value corresponding to type 3 PHR are both actual PH values. Actual PUCSH transmission and actual SRS transmission may have different closed-loop power states, or may correspond to different TCI states.

[0201] Optionally, type 1 PHR is determined based on a reference PUSCH transmission configuration, and type 3 PHR is determined based on a reference SRS transmission configuration, then the PH value corresponding to type 1 PHR and the PH value corresponding to type 3 PHR are both virtual PH values. The terminal may select a reference PUSCH transmission configuration from a predefined or preconfigured reference PUSCH transmission configuration, and select a reference SRS transmission configuration from a preconfigured or predefined reference SRS transmission configuration. The selected reference PUSCH transmission configuration and the selected reference SRS transmission configuration have different closed-loop power control adjustment states or different TCI states, so that more information is reported and more meaningful for reference. For example, the terminal may first select a reference PUSCH transmission configuration, and then select a reference SRS transmission configuration with a different closed-loop power control adjustment state or a different TCI state from the reference PUSCH transmission configuration. For another example, the terminal may first select a reference SRS transmission configuration, and then select a reference PUSCH transmission configuration with a different closed-loop power control adjustment state or a different TCI state from the reference SRS transmission configuration. There may be one or more predefined or preconfigured reference PUSCH transmission configurations, and accordingly, there may be one or more predefined or preconfigured reference SRS transmission configurations. For example, one reference PUSCH transmission configuration and one reference SRS transmission configuration may be preconfigured (or predefined), and the preconfigured (or predefined) reference PUSCH transmission configuration and the reference SRS transmission configuration have different closed-loop power control adjustment states or different TCI states. The terminal determines the PH value in the type 1 PHR based on the selected reference PUSCH transmission configuration, and the PH value is a virtual PH value. The terminal determines the PH value in the type 3 PHR based on the selected reference SRS transmission configuration, and the PH value is a virtual PH value.

[0202] Optionally, type 1 PHR is determined based on a reference PUSCH transmission configuration, and type 3 PHR is determined based on actual SRS transmission, then the PH value corresponding to type 1 PHR is a virtual PH value, and the PH value corresponding to type 3 PHR is an actual PH value. The terminal may select a reference PUSCH transmission configuration with a different closed-loop power adjustment state from the actual SRS transmission, or select a reference PUSCH transmission configuration with a different TCI state from the actual SRS transmission. Alternatively, the network device may also configure a reference PUSCH transmission configuration with a different closed-loop power adjustment state or a different TCI state from the actual SRS transmission. This enables more information to be reported and has greater reference significance. The terminal determines the PH value in type 1 PHR based on the selected reference PUSCH transmission configuration, and the PH value is a virtual PH value. The terminal determines the PH value in type 3 PHR based on actual SRS transmission, and the PH value is an actual PH value.

[0203] Optionally, type 1 PHR is determined based on actual PUSCH transmission, and type 3 PHR is determined based on reference SRS transmission configuration, then the PH value corresponding to type 1 PHR is an actual PH value, and the PH value corresponding to type 3 PHR is a virtual PH value. If there are multiple sets of reference SRS transmission configurations pre-configured or pre-defined, the terminal can select a reference SRS transmission configuration with a different closed-loop power adjustment state from the actual PUSCH transmission, or select a reference PUSCH transmission configuration with a different TCI state from the actual PUSCH transmission, so that more information is reported and it has greater reference significance. Alternatively, the network device can also configure a reference SRS transmission configuration with a different closed-loop power adjustment state or a different TCI state from the actual PUSCH transmission. The terminal can determine the PH value in type 1 PHR based on actual PUSCH transmission, and the PH value is an actual PH value. The terminal determines the PH value in type 3 PHR based on the selected reference SRS transmission configuration, and the PH value is a virtual PH value.

[0204] In some embodiments, if the terminal is configured to report multiple PHRs, and the type 3 PHR is determined based on the actual SRS transmission, and the terminal has multiple actual RSR transmissions, the terminal selects one from at least two actual SRS transmissions according to the second priority rule, and determines the PH value included in the type 3 PHR based on the selected SRS transmission.

[0205] Optionally, the type 1 PHR is determined based on the actual PUSCH transmission, the type 3 PHR is determined based on the actual SRS transmission, and the terminal has multiple actual RSR transmissions. The terminal determines the PH value included in the type 1 PHR based on the actual PUSCH transmission. The terminal selects one from at least two actual SRS transmissions according to the second priority rule, and determines the PH value included in the type 3 PHR based on the selected SRS transmission.

[0206] Optionally, type 1 PHR is determined based on a reference PUSCH transmission configuration, type 3 PHR is determined based on an actual SRS transmission, and the terminal has multiple actual SRS transmissions. The terminal can select one from at least two actual SRS transmissions according to a second priority rule, and determine the PH value included in the type 3 PHR based on the selected SRS transmission. Then select a reference PUSCH transmission configuration with a different closed-loop power adjustment state or a different TCI state from the selected actual SRS transmission, and determine the PH value in the type 1 PHR based on the selected reference PUSCH transmission configuration. For another example, the terminal first selects a reference PUSCH transmission configuration, and then selects an actual SRS transmission with a different closed-loop power adjustment state or a different TCI state from the reference PUSCH transmission configuration from at least two actual SRS transmissions according to the second priority rule. At this time, the second priority rule includes giving priority to SRS transmissions with a different closed-loop power control adjustment state from PUSCH transmission; or, giving priority to SRS transmissions with a different TCI state from PUSCH transmission.

[0207] In some embodiments, the second priority rule includes at least one of the following: giving priority to SRS transmission with a different closed-loop power control adjustment state from PUSCH transmission, and PUSCH transmission is used to determine type 1 PHR; giving priority to SRS transmission with a different TCI state from PUSCH transmission, and PUSCH transmission is used to determine type 1 PHR; giving priority to SRS transmission whose configuration function corresponding to the first transmission point TRP is beam management, and the first TRP is used for uplink transmission; giving priority to SRS transmission whose configuration function corresponding to the first TCI state is beam management, and the first TCI state is used for uplink transmission; giving priority to SRS transmission whose configuration function corresponding to the second TRP is beam management, and the second TRP is used for both uplink and downlink transmissions; giving priority to SRS transmission whose configuration function corresponding to the second TCIstate is beam management, and the second TCI state is used for both uplink and downlink transmissions; giving priority to SRS transmission whose configuration function is antenna switching; giving priority to SRS transmission with an earlier start transmission time; SRS transmission with a configuration function of codebook transmission has the lowest priority; SRS transmission with a configuration function of non-codebook transmission has the lowest priority.

[0208] Optionally, the second priority rule includes giving priority to SRS transmissions with different closed-loop power control adjustment states from PUSCH transmissions. For example, type 1 PHR is determined based on actual PUSCH transmissions, and actual SRS transmissions with different closed-loop power control adjustment states from actual PUSCH transmissions may be given priority from at least two actual SRS transmissions. For another example, type 1 PHR is determined based on a reference PUSCH transmission configuration, and a reference PUSCH transmission configuration may be selected first, and then from at least two actual SRS transmissions, an actual SRS transmission with a different closed-loop power control adjustment state from the reference PUSCH transmission configuration may be given priority.

[0209] Optionally, the second priority rule includes giving priority to SRS transmissions having a different TCI state from the PUSCH transmission. For example, the type 1 PHR is determined based on the actual PUSCH transmission, and the actual SRS transmission having a different TCI state from the actual PUSCH transmission can be given priority from at least two actual SRS transmissions. For another example, the type 1 PHR is determined based on a reference PUSCH transmission configuration, and a reference PUSCH transmission configuration can be selected first, and then from at least two actual SRS transmissions, the actual SRS transmission having a different TCI state from the reference PUSCH transmission configuration can be given priority.

[0210] Optionally, the second priority rule includes giving priority to SRS transmission whose configuration function corresponding to the first TRP is beam management, and the first TRP is used for uplink transmission. For example, when there are at least two SRS transmissions corresponding to different functions, they correspond to different TRPs. The SRS transmission whose function is beam management (BM) and corresponds to the first TRP can be given priority to determine the PH value contained in the type 3 PHR. For example, SRS supports 2 closed-loop power adjustment states, the closed-loop power adjustment state of the SRS transmission corresponding to the first TRP is i0, and the closed-loop power adjustment state of the second TRP is i1. Then the SRS transmission with a closed-loop power adjustment state of i0 can be given priority to determine the type 3 PHR. Among them, i0 and i1 are the indexes of the closed-loop power adjustment states, which can also be called the identifiers of the closed-loop power adjustment states. Among them, the first TRP is used for uplink transmission, for example, the first TRP can be the UL only TRP in the asymmetric M-TRP, which can also be called a micro node. The second TRP is used for both uplink and downlink transmissions. For example, the second TRP can be the primary gNB in ​​an asymmetric M-TRP scenario, which can also be called DL TRP.

[0211] Optionally, the second priority rule includes giving priority to the SRS transmission whose configuration function corresponding to the first TCI state is beam management. For example, when there are at least two SRS transmissions corresponding to different functions, corresponding to different TRPs, and the SRS does not support 2 closed-loop power adjustment states, the SRS transmission whose function is beam management and corresponding to the first TCI state can be given priority. Among them, when the SRS does not support 2 closed-loop power adjustment states, for example, only supports 1 closed-loop power adjustment state, the SRS transmission sent by the terminal to the first TRP and the SRS transmission sent to the second TRP correspond to the same closed-loop power adjustment state, then the terminal cannot select the SRS transmission corresponding to the first TRP according to the closed-loop power adjustment state. The first TRP and the second TRP can correspond to different TCI states. For example, if the first TRP corresponds to the first TCI state, the SRS transmission sent to the first TRP corresponds to the first TCI state, and the SRS transmission corresponding to the first TRP can be determined by selecting the SRS transmission corresponding to the first TRP.

[0212] Optionally, the second priority rule includes giving priority to SRS transmission whose configuration function corresponding to the second TRP is beam management, and the second TRP is used for both uplink transmission and downlink transmission. For example, when there are at least two SRS transmissions corresponding to different functions, they correspond to different TRPs. SRS transmission whose function is beam management and corresponds to the second TRP can be given priority to determine the PH value included in the type 3 PHR. Among them,

[0213] Optionally, the second priority rule includes giving priority to SRS transmission whose configuration function corresponding to the second TCI state is beam management, and the second TCI state is used for both uplink transmission and downlink transmission. For example, when there are at least two SRS transmissions corresponding to different functions and different TRPs, and SRS does not support 2 closed-loop power adjustment states, SRS transmission whose function is beam management and corresponds to the second TCI state can be given priority. The second TCI state is used for uplink transmission, for example, the second TCI state can be the TCI state of the second TRP.

[0214] Optionally, the second priority rule includes giving priority to SRS transmissions whose function is antenna switching. For example, when there are at least two SRS transmissions corresponding to different functions, the SRS transmission whose function is antenna switching may be given priority.

[0215] Optionally, the second priority rule includes giving priority to SRS transmissions with earlier start transmission times. For example, if there are at least two actual SRS transmissions in the time unit for reporting the PHR, then SRS transmissions with earlier start transmission times may be given priority.

[0216] Optionally, the second priority rule includes giving priority to SRS transmissions with a later start transmission time. For example, if there are at least two actual SRS transmissions in the time unit for reporting the PHR, then SRS transmissions with a later start transmission time may be given priority.

[0217] Optionally, the second priority rule includes that the SRS transmission function of codebook transmission has the lowest priority. For example, if there are at least two SRS transmissions corresponding to different functions, the SRS transmission function of codebook transmission has the lowest priority, that is, if there are SRS transmissions with multiple functions, the SRS transmission function of codebook is selected only when other selections fail.

[0218] Optionally, the second priority rule includes that the SRS transmission function of non-codebook transmission has the lowest priority. For example, if there are at least two SRS transmissions corresponding to different functions, the SRS transmission function of non-codebook transmission has the lowest priority, that is, if there are SRS transmissions with multiple functions, the SRS transmission function of non-codebook transmission is selected only when other selections fail.

[0219] In some embodiments, the disclosed embodiments support the case of a single carrier, for which at least one of type 1 PHR and type 3 PHR may be reported. The disclosed embodiments also support the case of multiple carriers, for which at least one of type 1 PHR and type 3 PHR may be reported for each carrier.

[0220] In some embodiments, when calculating the PH value, the terminal may consider or not consider the path loss offset value (PL offset). That is, the terminal determines the PH value based on parameters, and the parameters may include the PL offset or may not include the PL offset.

[0221] Optionally, if the function of the SRS corresponding to the type 3 PHR is beam management and / or antenna switching, the terminal determines that the parameter does not include a path loss offset value, and calculates the PH value based on the parameter.

[0222] Optionally, if the function of the SRS corresponding to the type 3 PHR is codeword (CB) transmission and / or non-codebook (NCB) transmission, the terminal determines that the parameters include a path loss offset value, and calculates the PH value based on the parameters.

[0223] Optionally, the terminal may assume that the path loss offset value is not included in the default parameters, and calculate the PH value based on the parameters.

[0224] Step S2103 , terminal 101 sends PHR to network device 102 .

[0225] In some embodiments, the network device 102 receives a PHR sent by the terminal 101, where the PHR includes at least one of a type 1 PHR and a type 3 PHR. The terminal has the capability of sending a type 1 PHR and a type 3 PHR on the same carrier.

[0226] In some embodiments, the terminal may send one or more carriers of the PHR to the network device. In one PHR report, the PHR includes the reported amount of one or more carriers. Alternatively, the PHR may include the reported amount of one or more cells. The number of carriers varies depending on the reporting mode. For example, the terminal may be configured to report the reported amount of one carrier, then the PHR includes the reported amount of one carrier, that is, the type 1 PHR includes the PH value and the maximum transmit power corresponding to the carrier, and / or the type 3 PHR includes the PH value and the maximum transmit power corresponding to the carrier. For another example, the terminal may be configured to report the reported amount of multiple carriers, then the PHR includes the reported amount of multiple carriers, that is, the type 1 PHR includes the PH value and the maximum transmit power corresponding to multiple carriers, and / or the type 3 PHR includes the PH value and the maximum transmit power corresponding to multiple carriers. It can be understood that when the terminal reports a type of PHR, the PHR may include the reported amount of one or more carriers (or cells). When the terminal reports multiple types of PHRs, each type of PHR may include the reported amount of one or more carriers (or cells).

[0227] In some embodiments, when the terminal reports multiple types of PHRs, and the terminal is configured to report the reporting amounts of multiple carriers (or cells), the reporting amounts in the PHR may include the PH values ​​and maximum transmit powers of multiple carriers corresponding to the type 1 PHR, and the PH values ​​and maximum transmit powers of multiple carriers corresponding to the type 3 PHR. Alternatively, the reporting amount in the PHR may include the PH values ​​of multiple carriers corresponding to the type 1 PHR, the PH values ​​of multiple carriers corresponding to the type 3 PHR, and the total maximum transmit power of multiple carriers.

[0228] It is understandable that the reporting amount in the present disclosure may also have other names, such as reporting content, or reporting information, or PHR information, etc.

[0251] Step S5101: The terminal sends a PHR to a network device.

[0252] Step S5102: The network device receives the PHR.

[0253] In some embodiments, the above method may include the method of the above-mentioned embodiments related to the communication system 100, the terminal 101, and the network device 102, which will not be repeated here.

[0254] The present disclosure provides a communication method:

[0255] When the terminal is configured with PUSCH on the carrier of the serving cell, and the terminal has the ability to support both type 1 and type 3 PHR, and SRS supports up to 2 closed-loop power control adjustment states, the following rules are applied to report PHR:

[0256] In some embodiments, the pH is calculated as:

[0257] Optionally, whether to include PL-offset is determined according to different usages. For example, when calculating PH for SRS used for BM and AS, PL offset configuration is not considered, while when calculating PH for SRS used for CB / NCB, PL-offset configuration needs to be considered.

[0258] Optionally, neither is taken into account in PL-offset.

[0259] In some embodiments, when the terminal is configured for single PHR reporting, if both type 1 and type 3 power headroom reports are based on their respective actual transmissions, the terminal reports a PHR report of type 1. If both type 1 and type 3 power headroom reports are based on their respective reference transmissions, a PHR report of type 1 is reported. If a type 1 report or a type 3 report is based on their respective reference transmissions, only a type 1 or type 3 power headroom report based on the corresponding actual transmission is reported.

[0260] In some embodiments, if there are two SRSs actually transmitted at the same time, the reported SRS transmission is selected for measurement reporting according to a predetermined rule. The predetermined rule is as follows:

[0261] Optionally, the SRS of the BM corresponding function of the UL TRP is reported preferentially.

[0262] Optionally, the SRS of the BM corresponding function of the DL TRP is reported preferentially.

[0263] Optionally, the priority reporting function is the SRS of the AS.

[0264] Optionally, define the SRS measurement report corresponding to CB / NCB as the lowest priority.

[0265] In some embodiments, when the network is configured for multiple PHR reporting, the terminal reports both type 1 and type 3 PHR reports simultaneously.

[0266] In some embodiments, both type 1 and type 3 power headroom reports are based on their actual transmissions. If there are two SRS actual transmissions at the same time, a type 1 PHR is reported, and a type 3 PHR corresponding to the reported SRS transmission is selected according to a predetermined rule. The predetermined rule is as follows:

[0267] Optionally, an SRS having a closed-loop power control adjustment state different from that of a PUSCH is preferentially measured and reported.

[0268] Optionally, the SRS of the BM corresponding function of the UL TRP is preferentially measured and reported.

[0269] Optionally, the SRS of the BM corresponding to the DL TRP is preferentially measured and reported.

[0270] Optionally, the SRS whose reporting function is AS is preferentially measured.

[0271] Optionally, define the SRS measurement report corresponding to CB / NCB as the lowest priority.

[0272] In some embodiments, both type 1 and type 3 power headroom reports are based on their own reference transmissions. Type 1 PHR is reported based on the PUSCH reference configuration, and type 3 PHR is reported at the same time. The reference transmission configuration corresponding to type 3 PHR preferentially selects SRS transmissions with different closed-loop power control adjustment states from PUSCH for calculation and reporting.

[0273] In some embodiments, the reference configurations of SRS and PUSCH allow multiple configurations, including at least the SRS reference configuration function as BM or AS.

[0274] In some embodiments, the configuration of the closed-loop power control state is as follows: Configuration 1 (Config1) PUSCH {i0}, SRS {i1}; Config2: SRS {i0}, PUSCH {i1}, wherein i0 and i1 are indexes of the closed-loop power control state.

[0275] In some embodiments, type 1 report or type 3 report is based on actual transmission, and the other type report is obtained based on reference transmission. The reference transmission configuration preferentially selects SRS with different closed-loop power control adjustment states from PUSCH for calculation, and selects from multiple defined reference configurations.

[0276] In some embodiments, the method is applicable to reporting of a single component carrier (CC) and multiple CCs.

For another example, another device is also proposed, including a unit or module for implementing each step performed by a network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.

In a reconfigurable hardware circuit, the process of the processor loading a configuration document and realizing the configuration of the hardware circuit may be understood as the process of the processor loading instructions to realize the functions of some or all of the above units or modules. In addition, it may also be a hardware circuit designed for artificial intelligence, which may be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
