[0024] To facilitate understanding, we first explain terminology relevant to this disclosure.

[0025] 1. Power headroom report (PHR) The PHR reflects the available power, i.e., power headroom, of a terminal device. For controlling uplink transmission, the PHR needs to be measured and reported to a network device.

[0026] Here, what is mainly relevant to multi-TRP uplink transmission is the Type 1 power headroom report, which includes the power headroom and the maximum transmit power (Pcmax) of the component carrier where it is located, where Pcmax is set for the terminal device by the network device. Since the network knows the coding and modulation scheme at the time corresponding to the power headroom report and the resource size of the terminal device used for transmission, it can determine the effective combination of the modulation and coding scheme (MCS) and the allocated resource size. When there is no actual PUSCH transmission, the terminal may report the Type 1 power headroom.

[0027] Current PHR measurement mechanisms are divided into actual PHR and virtual PHR. When there is physical uplink shared channel (PUSCH) transmission, the terminal device reports the actual PHR to the network device. When there is no PUSCH transmission, the terminal device calculates one PHR based on a predefined PUSCH format and reports it to the network device, i.e., reports a virtual PHR. The network device determines the bandwidth and transmission mode in which the terminal device can transmit based on the power difference information of the terminal device.

[0028] 2. Transmission and receiving point (TRP) A TRP corresponds to a conventional base station, but in some cases a cell may not be covered by a single TRP, but may be jointly covered by multiple TRPs.

[0029] 3. PUSCH The PUSCH is used to carry data from the transport channel USCH. Shared refers to the fact that the same physical channel can be used by multiple terminal devices in a time-shared manner, or the channel may be said to have a short duration.

[0030] 4. Uplink simultaneous transmission of multi-panel (STxMP) By utilizing cooperation between multiple panels to transmit / receive channels from multiple wave packets at multiple angles, various blockage or blocking effects can be better overcome and the robustness of the link connection can be ensured.

[0031] 5. Medium access control element (MAC CE) MAC CE is a means for exchanging control information between a terminal device and a network device, and is mainly control information related to the MAC layer.

[0032] To better understand the power headroom reporting method based on multi-panel transmission disclosed in the embodiments of the present disclosure, the following first describes a communication system to which the embodiments of the present disclosure are applied.

[0033] Referring to FIG. 1, FIG. 1 is a schematic diagram of a communication system architecture provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, one network device, such as a TRP and one terminal device. The number and configuration of devices shown in FIG. 1 are exemplary and do not limit the embodiments of the present disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. For example, the communication system shown in FIG. 1 includes two TRPs, TRP11 and TRP12, and one terminal device 13.

[0034] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a long term evolution (LTE) system, a fifth generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems.

[0035] In the embodiments of the present disclosure, TRP11 and TRP12 are network-side entities for transmitting and receiving signals. For example, they may be an evolved base station (eNB), a transmission reception point (TRP), a next-generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, respectively. The embodiments of the present disclosure do not limit the specific technology and device form used by the network device. The network device provided by the embodiments of the present disclosure may be composed of a central unit (CU) and distributed units (DUs), and the CU may be referred to as a control unit. Using a CU-DU structure, the protocol layers of the network device, for example, a base station, may be divided, with some protocol layer functions centrally controlled by the CU and the remaining or all protocol layer functions distributed to the DUs, and the CU centrally controls the DUs. In the present disclosure, the TRP may be replaced by a remote radio head, an antenna panel, or the like.

[0036] In the embodiments of the present disclosure, the terminal device 13 is a user-side entity for transmitting and receiving signals, such as a mobile phone. The terminal device may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet, a computer with wireless transmission and reception capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and device form used by the terminal device.

[0037] It should be noted that the communication system described in the embodiments of the present disclosure is intended to more clearly explain the technical solutions of the embodiments of the present disclosure, and does not limit the technical solutions provided by the embodiments of the present disclosure. As can be appreciated by those skilled in the art, with the evolution of system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure can also be applied to similar technical problems.

[0038] In the present disclosure, each panel of a terminal device has an independent power amplifier (PA) implementation structure, and therefore can support an independent power control process. Therefore, a maximum transmission power (Pcmax) can be set for the terminal device, or a corresponding maximum transmission power (Pcmax,p) can be set for each panel of the terminal device. Therefore, in the present disclosure, when the terminal device is configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report or in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, the terminal device can calculate and report a power headroom report (PHR) according to at least one actual PH based on the maximum power setting. Then, the network device can determine the power headroom (PH) of the terminal device based on the PHR and perform resource scheduling for each panel based on the PH, thereby ensuring the reliability of uplink transmission.

[0039] It should be noted that in the present disclosure, the power headroom reporting method based on multi-panel transmission provided by any one of the embodiments may be implemented alone, or may be implemented together with possible implementation methods in other embodiments, or may be implemented in combination with any one of the technical solutions in the related art.

[0044] DETAILED DESCRIPTION OF THE DISCLOSURE

[0013] Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, in which like or similar reference characters refer to like or similar elements throughout. The embodiments described below with reference to the drawings are merely exemplary and are intended to illustrate, but not limit, the present invention.

[0045] 2, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, the method being executed by a multi-panel terminal device. As shown in FIG. 2, the method may include, but is not limited to, the following step 201:

[0046] In step 201, in a first transmission slot or a slot that satisfies a timeline requirement corresponding to a physical uplink shared channel (PUSCH) carrying a media access control (MAC) control element (CE) PHR report, in response to the terminal device being configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH and the actual PUSCH transmission being a transmission from a single panel to a single TRP, the terminal device calculates and reports a power headroom report (PHR) according to at least one actual PH based on the maximum power setting of the terminal device.

[0047] Here, the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report is the transmission slot with the smallest time-frequency domain position among the transmission slots corresponding to the PUSCH carrying the MAC CE PHR report, determined based on downlink control information (DCI). The slot satisfying the timeline requirement may be a slot satisfying the timeline requirement of the PHR report, determined by the terminal device based on a protocol agreement or an instruction from the network device.

[0048] In the present disclosure, when a terminal device performs uplink transmission, it needs to report a PHR to a network device to ensure the reliability of uplink transmission. If the terminal device is configured for uplink STxMP of multiple TRPs corresponding to the PUSCH in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, or if the terminal device is configured for uplink STxMP of multiple TRPs corresponding to the PUSCH in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, it can calculate and report a PHR according to at least one actual PH based on the maximum power setting of the terminal device.

[0049] After the terminal device calculates and reports the PHR, the network device can determine the power headroom of the terminal device based on the PHR, and in combination with the current coding and modulation method of the terminal device, accurately determine the bandwidth and transmission mode that the panel of the terminal device can transmit, thereby ensuring the reliability of uplink transmission.

[0050] Alternatively, the maximum power setting of the terminal device may include a maximum transmission power (Pcmax) for the terminal device, a maximum transmission power (Pcmax,p) for a different panel, or may include both Pcmax and Pcmax,p, and the present disclosure is not limited in this regard.

[0051] Here, the PHR may include an actual PH value calculated based on the maximum transmission power and the power used to actually transmit the PUSCH, or may include a virtual PH value and a field for indicating a reference format for the virtual PH. Here, the virtual PH is a virtual value calculated based on the maximum transmission power and a predefined PUSCH format. The field for indicating the reference format for the virtual PH may indicate whether the reported PH value is determined based on actual transmission or based on a reference format. For example, setting the value of the field for indicating the reference format of the PHR to 0 indicates that the reported PH value is an actual PH value determined based on actual transmission, and setting the value of the field for indicating the reference format of the PHR to 1 indicates that the reported PH value is a virtual PH value determined based on a reference format.

[0052] Alternatively, the terminal device may calculate and report a PHR based on at least one actual PH based on the maximum transmission power (Pcmax) for the terminal device, or may calculate and report a PHR based on at least one actual PH based on the maximum transmission power (Pcmax,p) for a different panel, or may calculate and report a PHR based on at least one actual PH based on Pcmax and Pcmax,p, and the present disclosure is not limited thereto.

[0053] Optionally, the terminal device may calculate and report at least one actual PHR according to an actual PH based on a maximum power setting of the terminal device, and calculate and report at least one PHR according to a virtual PH.

[0054] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single downlink control information (DCI) using a space division multiplexing (SDM) scheme or a frequency division multiplexing (FDM) scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR may be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0055] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a time division multiplexing (TDM) scheme based on multiple DCIs to realize multi-panel uplink STxMP. Therefore, when PUSCHs are transmitted using a coordinated transmission scheme scheduled based on multiple DCIs, the reference format of the virtual PHR may be determined based on the PUSCH transmission schemes of different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission schemes.

[0056] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report or in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, the terminal device calculates a PH according to at least one actual PH based on the maximum power setting, and reports a PHR when the PHR reporting condition is met.

[0057] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to the PUSCH carrying a MAC CE PHR report or in a slot that satisfies a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, the terminal device can calculate and report a PHR according to at least one actual PH based on the maximum power setting. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0058] 3, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, the method being executed by a multi-panel terminal device. As shown in FIG. 3, the method may include, but is not limited to, the following step 301:

[0059] In step 301, in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot that meets a timeline requirement, the terminal device is configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH, the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is the maximum transmission power (Pcmax) for the terminal device, in response to which the terminal device calculates and reports a PHR based on at least one actual PH based on Pcmax.

[0060] In the present disclosure, when the maximum power setting of a terminal device is Pcmax for the terminal device, the terminal device can perform power allocation for Pcmax according to a preset power allocation rule, and calculate and report PHR according to at least one actual PH.

[0061] Alternatively, the terminal device can determine the maximum transmission power corresponding to each panel by performing power allocation for Pcmax according to an average allocation rule. For example, if Pcmax is 23 decibels relative to one milliwatt (dBm) and the terminal device has two panels, the maximum transmission power corresponding to each panel can be determined to be 20 dBm based on the average allocation rule.

[0062] Alternatively, the terminal device can determine the maximum transmission power corresponding to each panel by performing power allocation for Pcmax according to a dynamic allocation rule, where the dynamic allocation rule may be instructed by the network device or determined based on a protocol agreement. For example, if the actual power output capabilities of two panels of a terminal are different, and panel #2 has a larger power amplifier and supports a higher actual transmission power, dynamic allocation between the two panels may be considered based on PA capabilities. For example, if panel #1 supports a PA of 23 dBm and panel #2 supports a PA of 26 dBm, and the maximum transmission power of the terminal is set to 26 dBm, transmission power may be allocated between the two panels based on an average method, or dynamic allocation between the two panels may be considered based on PA capabilities. Alternatively, dynamic allocation between the two panels may be considered based on PA capabilities, where, for example, the maximum transmission power of panel #2 accounts for 70% of the maximum transmission power of the terminal device. At this time, if the Pcmax of the terminal device is 26 dBm, based on the dynamic allocation rule, it can be determined that when panel #1 occupies 30%, the maximum transmission power corresponding to panel #1 is 21 dBm and the maximum transmission power corresponding to panel #2 is 24.5 dBm.

[0063] In the present disclosure, the PUSCH transmitted by the terminal device is transmitted from a single panel to a single TRP, but is configured to STxMP of multiple transmission / reception points (TRPs) for the PUSCH, that is, the network device schedules the terminal to transmit the PUSCH to one of the TRPs through a panel in this case, and at this time, one panel out of the multiple panels in the terminal device transmits the PUSCH, and the terminal device can calculate the actual PHR of the one panel that actually transmits the PUSCH.

[0064] Optionally, the terminal device may calculate and report an actual PHR of the first panel corresponding to the actual PUSCH transmission according to a power allocation rule based on Pcmax, where the actual PHR is associated with a transmission occasion corresponding to the PUSCH transmission in the first panel.

[0065] Alternatively, the terminal device may calculate and report an actual PHR of a first panel corresponding to an actual PUSCH transmission according to an actual PH according to a power allocation rule based on Pcmax, and calculate and report a virtual PHR of another panel according to a virtual PH, where the actual PHR is associated with a transmission occasion corresponding to a PUSCH transmission in the first panel, and the virtual PHR is associated with a transmission occasion corresponding to a PUSCH transmission reference assumption in the other panel.

[0066] For example, the terminal device determines the maximum transmission power corresponding to each panel based on Pcmax and in accordance with the power allocation rule, calculates the actual PH corresponding to the first panel and the virtual PH corresponding to any one panel other than the first panel, and reports the PHR corresponding to each of the two panels.

[0067] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR can be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0068] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR can be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0069] In the present disclosure, for a specific description of the PHR, please refer to the detailed description of any embodiment of the present disclosure, and a detailed description will be omitted here.

[0070] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to the PUSCH carrying a MAC CE PHR report or in a slot that satisfies a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, the terminal device can calculate and report a PHR based on at least one actual PH based on the maximum power setting for the terminal device. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0071] 4, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, the method being executed by a multi-panel terminal device. As shown in FIG. 4, the method may include, but is not limited to, the following step 401:

[0072] In step 401, in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot that meets the timeline requirement, the terminal device is configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH, the actual PUSCH transmission is transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is the maximum transmission power (Pcmax,p) for different panels, in response to which the terminal device calculates and reports a PHR based on at least one actual PH based on Pcmax,p corresponding to at least one panel, where p is a positive integer less than or equal to N, and N is the number of panels in the terminal device.

[0073] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to the PUSCH carrying a MAC CE PHR report or in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device includes maximum transmission power (Pcmax,p) of different panels, the terminal device calculates and reports a PHR based on at least one actual PH based on Pcmax,p corresponding to at least one panel.

[0074] Optionally, the terminal device calculates and reports an actual PHR of the first panel based on a first Pcmax,p corresponding to the first panel corresponding to the actual PUSCH transmission, where the actual PHR is associated with a transmission occasion corresponding to the PUSCH transmission in the first panel.

[0075] Alternatively, the terminal device calculates and reports an actual PHR of the first panel and a virtual PHR of the other panel according to the actual PH and the virtual PH, respectively, based on the first Pcmax,p and the second Pcmax,p corresponding to the other panel, where the actual PHR is associated with a transmission occasion corresponding to a PUSCH transmission in the first panel, and the virtual PHR is associated with a transmission occasion corresponding to a PUSCH transmission reference assumption in the other panel.

[0076] Here, the other panel may be any panel other than the first panel.

[0077] For example, if the first panel corresponding to the actual PUSCH transmission is panel #1, the terminal device can calculate an actual PHR #1 according to the actual PH based on Pcmax,p #1 corresponding to panel #1, and simultaneously calculate a virtual PHR #2 according to the virtual PH based on Pcmax,p #2 corresponding to panel #2, where PHR #1 is associated with a transmission occasion corresponding to the PUSCH transmission in panel #1, and PHR #2 is associated with a transmission occasion corresponding to the PUSCH transmission in panel #2, and report PHR #1 and PHR #2 to the network device.

[0078] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR may be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0079] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR can be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0080] In the present disclosure, for a specific description of the PHR, please refer to the detailed description of any embodiment of the present disclosure, and a detailed description will be omitted here.

[0081] In the present disclosure, in the first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report or in a slot that satisfies a timeline requirement, a terminal device is configured for uplink STxMP of multiple TRPs corresponding to the PUSCH, and when the actual PUSCH transmission is a transmission from a single panel to a single TRP and the maximum power setting of the terminal device is the maximum transmission power (Pcmax,p) for a different panel, the terminal device calculates and reports the PHR based on at least one actual PH based on Pcmax,p corresponding to at least one panel. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0082] 5, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, the method being executed by a multi-panel terminal device. As shown in FIG. 5, the method may include, but is not limited to, the following step 501:

[0083] In step 501, in the first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report, or in a slot that meets a timeline requirement, the terminal device is configured with uplink STxMPs of multiple TRPs corresponding to the PUSCH, the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is Pcmax and Pcmax,p corresponding to each panel, in response to which the terminal device jointly calculates and reports a PHR according to at least one actual PH based on Pcmax and Pcmax,p.

[0084] Alternatively, the terminal device may calculate and report an actual PHR of a first panel corresponding to the actual PUSCH transmission according to the actual PH based on the Pcmax,p, or may calculate and report an actual PHR of the first panel according to the actual PH based on a first Pcmax,p corresponding to the first panel corresponding to the actual PUSCH transmission.

[0085] For example, a terminal device includes panel 1 and panel 2, where the first panel corresponding to actual PUSCH transmission is panel 1. Thus, the transmission power of panel 1 is p1, and transmission power p2 is obtained by calculation using the transmission reference assumption of panel 2. Based on Pcmax and Pcmax,p1, actual power headrooms corresponding to panel 1 are obtained by calculation according to actual PH, which are PH1 and PH1′, respectively. Based on Pcmax and Pcmax,p2, virtual power headrooms corresponding to panel 2 are obtained by calculation according to virtual PH, which are PH2 and PH2′, respectively. Therefore, the terminal device may report PH1 to the network device, or may report PH1′ to the network device, and the present disclosure is not limited thereto.

[0086] Alternatively, the terminal device may further calculate and report two actual PHRs of the first panel based on the Pcmax and a first Pcmax,p corresponding to the first panel corresponding to the actual PUSCH transmission. Alternatively, the terminal device may further calculate and report an actual PHR of the first panel corresponding to the actual PUSCH transmission according to the actual PH based on the Pcmax, and calculate and report a virtual PHR of another panel according to a virtual PH. Alternatively, the terminal device may further calculate and report an actual PHR of the first panel according to the actual PH based on the first Pcmax,p, and calculate and report a virtual PHR of the other panel according to a virtual PH based on a second Pcmax,p corresponding to the other panel.

[0087] That is, referring to the above example, the terminal device may report PH1 and PH1' to the network device, or may report PH1 and PH2 to the network device, or may report PH1' and PH2' to the network device.

[0088] Alternatively, the terminal device can calculate and report the actual PHR of the first panel according to the actual PH based on the first Pcmax,p, calculate and report the actual PHR of the first panel according to the actual PH based on the Pcmax, and calculate and report the virtual PH of another panel according to the virtual PH.

[0089] For example, a terminal device includes panel 1 and panel 2, where the first panel corresponding to actual PUSCH transmission is panel 1, the transmission power of panel 1 is p1, and the transmission power p2 is calculated using the transmission reference assumption of panel 2, and the actual power headroom corresponding to panel 1 is calculated according to the actual PH based on Pcmax and Pcmax,p1, and the actual power headroom corresponding to panel 1 is calculated according to the virtual PH, and the virtual power headroom corresponding to panel 2 is calculated according to the virtual PH, and the virtual power headroom is calculated according to Pcmax and Pcmax,p2, and the virtual power headroom corresponding to panel 2 is calculated according to the virtual PH, and the virtual power headroom is reported to the network device. Therefore, the terminal device can report PH1, PH1', and PH2 to the network device.

[0090] Optionally, the terminal device may further calculate and report two actual PHRs corresponding to the first panel based on the Pcmax and a first Pcmax,p corresponding to the first panel, and calculate and report a virtual PHR of another panel based on a second Pcmax,p corresponding to another panel.

[0091] That is, referring to the above example, the terminal device can report PH1', PH1 and PH2' to the network device.

[0092] Optionally, the terminal device may further calculate and report an actual PHR of the first panel according to the actual PH based on the first Pcmax,p, and calculate and report two virtual PHRs corresponding to the other panel based on the Pcmax and a second Pcmax,p corresponding to the other panel, respectively.

[0093] That is, referring to the above example, the terminal device may further report PH1', PH2 and PH2' to the network device.

[0094] Alternatively, the terminal device may further calculate and report an actual PHR of the first panel according to the actual PH based on the Pcmax, and calculate and report two virtual PHRs corresponding to the other panel based on the Pcmax and a second Pcmax,p corresponding to the other panel, respectively.

[0095] That is, referring to the above example, the terminal device may report PH1, PH2 and PH2' to the network device.

[0096] Optionally, the terminal device further calculates and reports one actual PHR for the first panel based on the first Pcmax,p, calculates and reports one virtual PHR corresponding to the other panel based on the second Pcmax,p, and calculates and reports one PHR corresponding to the terminal device in combination with the Pcmax.

[0097] For example, a terminal device includes panel 1 and panel 2, where the first panel corresponding to the actual PUSCH transmission is panel 1, the transmit power of panel 1 is p1, and the transmit power p2 is calculated using the transmission reference assumption of panel 2. Based on Pcmax and Pcmax,p1, the actual power headroom corresponding to panel 1 is calculated according to the actual PH, and these are PH1 and PH1', respectively. Based on Pcmax and Pcmax,p2, the virtual power headroom corresponding to panel 2 is calculated according to the virtual PH, and these are PH2 and PH2', respectively. Also, corresponding to p1 and p2, the terminal device may have a transmit power p3 in a multi-panel transmission scheme, and calculate PH3 based on Pcmax to obtain PH3, where PH3 may be the actual PH or the virtual PH. At this time, the terminal device may report PH1', PH2', and PH3 to the network device.

[0098] Alternatively, the terminal device may further calculate and report two actual PHRs corresponding to the first panel based on the Pcmax and a first Pcmax,p corresponding to the first panel, and calculate and report two virtual PHRs corresponding to the other panel based on the Pcmax and a second Pcmax,p corresponding to the other panel.

[0099] That is, referring to the above example, the terminal device can report PH1, PH1', PH2 and PH2' to the network device.

[0100] Optionally, the terminal device may further calculate and report two actual PHRs corresponding to the first panel based on Pcmax and a first Pcmax,p corresponding to the first panel, calculate and report two virtual PHRs corresponding to the other panel based on Pcmax and a second Pcmax,p corresponding to the other panel, and calculate and report one PHR corresponding to the terminal device in combination with Pcmax.

[0101] That is, referring to the above example, the terminal device can report PH1, PH1', PH2, PH2' and PH3 to the network device.

[0102] Wherein, each actual PHR is associated with a transmission occasion corresponding to a PUSCH transmission in the first panel, and each virtual PHR is associated with a transmission occasion corresponding to a PUSCH transmission reference hypothesis in the other panel. In the present disclosure, for a specific description of PHR, please refer to the detailed description of any embodiment of the present disclosure, and a detailed description will be omitted here.

[0103] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR can be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0104] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR can be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0105] In the present disclosure, when a terminal device is configured with uplink STxMP for multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to the PUSCH carrying a MAC CE PHR report or in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is Pcmax,p for the panel and Pcmax for the terminal device, the actual PHR can be calculated and reported according to at least the actual PH based on Pcmax,p, so that the network device can determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0106] Referring to Figure 6, Figure 6 is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, which is executed by a multi-panel terminal device. As shown in Figure 6, the method may include, but is not limited to, the following steps 601 to 602:

[0107] In step 601, receiving indication information sent from a network device, where the indication information indicates a reporting manner of a PHR.

[0108] Here, the reporting method of the PHR may include at least one of reporting one PHR, reporting two PHRs, reporting three PHRs, or reporting four PHRs.

[0109] In the present disclosure, the network device can instruct the terminal device to report the PHR according to the terminal device's ability to report the PHR. For example, if the terminal device's ability to report the PHR is to report four PHRs, the network device can instruct the terminal device to report one PHR, or two PHRs, or three PHRs, or four PHRs.

[0110] In step 602, in a first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report or a slot that satisfies a timeline requirement, in response to the terminal device being configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH and the actual PUSCH transmission being a transmission from a single panel to a single TRP, calculate and report a power headroom report (PHR) according to at least one actual PH based on a maximum power setting of the terminal device.

[0111] In the present disclosure, when a network device instructs a terminal device to report one PHR, the terminal device can calculate and report an actual PHR corresponding to a first panel corresponding to the transmission of an actual PUSCH according to the actual PH.

[0112] Alternatively, when the network device instructs the terminal device to report two PHRs, the terminal device may calculate and report an actual PHR2 corresponding to a first panel corresponding to the actual PUSCH transmission and a virtual PHR corresponding to another panel. Alternatively, the terminal device may calculate and report one actual PHR corresponding to the first panel based on a first Pcmax corresponding to the first panel, and calculate and report another actual PHR corresponding to the first panel based on the Pcmax of the terminal device in accordance with a power allocation rule, and the present disclosure is not limited thereto.

[0113] Alternatively, when the network device instructs the terminal device to report three PHRs, the terminal device may calculate and report two actual PHRs corresponding to the first panel and one virtual PHR corresponding to the other panel based on the Pcmax of the terminal device and the Pcmax,p corresponding to the first panel, or may report one actual PHR corresponding to the first panel and two virtual PHRs corresponding to the other panel, and the present disclosure is not limited thereto.

[0114] Alternatively, if the network device can instruct the terminal device to report four PHRs, the terminal device can calculate and report two actual PHRs corresponding to the first panel and two virtual PHRs corresponding to another panel based on the Pcmax of the terminal device and the Pcmax,p corresponding to the first panel.

[0115] In the present disclosure, for specific descriptions of the maximum power setting of the terminal device and the determination and reporting of the virtual PHR, please refer to the detailed description of any embodiment of the present disclosure, and detailed descriptions will be omitted here.

[0116] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR may be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0117] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR can be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0118] In the present disclosure, after receiving second instruction information transmitted from a network device to indicate a PHR reporting method, the terminal device configures uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH in a first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report or in a slot that satisfies a timeline requirement, and calculates and reports a power headroom report (PHR) according to at least one actual PH based on the maximum power setting of the terminal device. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0119] 7, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, which is executed by a network device. As shown in FIG. 7, the method may include, but is not limited to, the following step 701:

[0120] In step 701, in a first transmission slot or a slot that satisfies a timeline requirement corresponding to a physical uplink shared channel (PUSCH) in which a terminal device carries a media access control control element (MAC CE) PHR report, in response to the terminal device being configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH and the actual PUSCH transmission being a transmission from a single panel to a single TRP, it is determined that the power headroom report (PHR) reported by the terminal device is calculated according to at least one actual PH based on the maximum power setting of the terminal device.

[0121] Here, the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report may be a transmission slot with the smallest time-frequency domain position among the transmission slots corresponding to the PUSCH carrying the MAC CE PHR report, determined based on downlink control information (DCI). The slot satisfying the timeline requirement may be a slot satisfying the timeline requirement of the PHR report, determined by the terminal device based on a protocol agreement or an instruction from a network device.

[0122] In the present disclosure, when a terminal device performs uplink transmission, it needs to report a PHR to a network device to ensure the reliability of the uplink transmission. If the terminal device is configured for uplink STxMP of multiple TRPs corresponding to the PUSCH in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, or if the terminal device is configured for uplink STxMP of multiple TRPs corresponding to the PUSCH in a slot that satisfies a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, it can be determined that the PHR reported by the terminal device is calculated by the terminal device according to at least one actual PH based on the maximum power setting of the terminal device.

[0123] After the terminal device calculates and reports the PHR, the network device can determine the power headroom of the terminal device based on the PHR, and can accurately determine the bandwidth and transmission mode that the panel of the terminal device can transmit based on the current coding and modulation method of the terminal device, thereby ensuring the reliability of uplink transmission.

[0124] Alternatively, the maximum power setting of the terminal device may include a maximum transmission power (Pcmax) for the terminal device, or may be a maximum transmission power (Pcmax,p) for a different panel, or may include both Pcmax and Pcmax,p, and the present disclosure is not limited thereto.

[0125] Here, the PHR may include an actual PH value calculated based on the maximum transmission power and the power used to actually transmit the PUSCH, or may include a virtual PH value and a field for indicating a reference format for the virtual PH. Here, the virtual PH is a virtual value calculated based on the maximum transmission power and a predefined PUSCH format. The field for indicating the reference format for the virtual PH may be used to indicate whether the reported PH value is determined based on actual transmission or based on a reference format. For example, setting the value of the field for indicating the reference format of the PHR to 0 indicates that the reported PH value is determined based on actual transmission, and setting the value of the field for indicating the reference format of the PHR to 1 indicates that the reported PH value is determined based on a reference format.

[0126] Optionally, in response to the maximum power setting of the terminal device being a maximum transmit power (Pcmax) for the terminal device, the network device may determine that the PHR reported by the terminal device is calculated according to at least one actual PH based on Pcmax.

[0127] Alternatively, in response to the terminal device's maximum power setting being the maximum transmission power (Pcmax,p) for a different panel, the network device determines that the PHR reported by the terminal device is calculated according to at least one actual PH based on Pcmax,p corresponding to at least one panel.

[0128] Alternatively, in response to the maximum power setting type of the terminal device being Pcmax and Pcmax,p corresponding to each panel, the network device can determine that the PHR reported by the terminal device is jointly calculated according to at least one actual PH based on Pcmax and Pcmax,p, and the present disclosure is not limited in this regard.

[0129] Optionally, the terminal device may further calculate and report at least one actual PHR according to an actual PH based on a maximum power setting of the terminal device, and calculate and report at least one virtual PHR according to a virtual PH.

[0130] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single downlink control information (DCI) using a space division multiplexing (SDM) scheme or a frequency division multiplexing (FDM) scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR can be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0131] Alternatively, PUSCH transmission may be scheduled based on multi-DCI using an SDM scheme, an FDM scheme, or a time division multiplexing (TDM) scheme to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR can be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0132] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report or in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, the network device can determine that the PHR reported by the terminal device is calculated according to at least one actual PH based on the maximum power setting of the terminal device.

[0133] In the present disclosure, a network device determines that a terminal device is configured with uplink STxMPs of multiple TRPs corresponding to a PUSCH carrying a MAC CE PHR report in the first transmission slot corresponding to the PUSCH or in a slot that satisfies a timeline requirement, and that the actual PUSCH transmission is a transmission from a single panel to a single TRP. This allows the network device to determine that the power headroom report (PHR) reported by the terminal device is calculated according to at least one actual PH based on the maximum power setting of the terminal device. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0134] 8, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, the method being executed by a network device. As shown in FIG. 8, the method may include, but is not limited to, the following step 801:

[0135] In step 801, in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot that meets the timeline requirement, the terminal device is configured to uplink STxMPs of multiple TRPs corresponding to the PUSCH, the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is the maximum transmission power (Pcmax) for the terminal device, it is determined that the PHR reported by the terminal device is calculated according to at least one actual PH based on Pcmax.

[0136] In the present disclosure, if the maximum power setting of the terminal device is Pcmax for the terminal device, the network device can determine that the PHR reported by the terminal device is calculated according to at least one actual PH based on a power allocation rule preset by it.

[0137] Alternatively, the terminal device may perform power allocation for Pcmax according to an average allocation rule, or the terminal device may perform power allocation for Pcmax according to a dynamic allocation rule, where the dynamic allocation rule may be instructed by the network device or determined by a protocol agreement, and the present disclosure is not limited thereto.

[0138] Here, for the specific implementation manner in which a terminal device performs power allocation based on a power allocation rule and calculates and reports a PHR, please refer to the detailed description of any one of the embodiments of the present disclosure, and detailed description will be omitted here.

[0139] In the present disclosure, the PUSCH transmitted by the terminal device is a transmission from a single panel to a single TRP, but is set to STxMP of multiple transmission / reception points (TRPs) for the PUSCH, that is, the terminal scheduled by the network device transmits the PUSCH to one of the TRPs through a panel in this case, so that one panel out of the multiple panels in the terminal device at this time transmits the PUSCH, and therefore the network device can determine that the PHR reported by the terminal device is the actual PHR of one panel that actually transmits the PUSCH, calculated by the terminal device.

[0140] Optionally, if the terminal device reports one PHR, the network device can determine that the one PHR reported by the terminal device is an actual PHR of the first panel corresponding to an actual PUSCH transmission calculated by the terminal device according to a power allocation rule based on Pcmax, where the actual PHR is associated with a transmission occasion corresponding to the PUSCH transmission in the first panel.

[0141] Alternatively, if the terminal device reports two PHRs, the network device can determine that the two PHRs include an actual PHR of a first panel corresponding to the actual PUSCH transmission calculated by the terminal device according to the actual PH in accordance with a power allocation rule based on Pcmax, and a virtual PHR of another panel calculated according to the virtual PH.

[0142] Here, the actual PHR is associated with a transmission occasion corresponding to a PUSCH transmission in a first panel, and the virtual PHR is associated with a transmission occasion corresponding to a PUSCH transmission reference hypothesis in another panel.

[0143] For example, the terminal device determines the maximum transmission power corresponding to each panel based on Pcmax and in accordance with the power allocation rule, calculates the actual PH corresponding to the first panel and the virtual PH corresponding to any one panel other than the first panel, and reports the PHR corresponding to each of the two panels.

[0144] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR can be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0145] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR may be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0146] In the present disclosure, for a specific description of the PHR, please refer to the detailed description of any embodiment of the present disclosure, and a detailed description will be omitted here.

[0147] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to the PUSCH carrying a MAC CE PHR report or in a slot that satisfies a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is Pcmax, the network device can determine that the PHR reported by the terminal device is calculated according to at least one actual PH based on Pcmax. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0148] 9, which is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, which is executed by a network device. As shown in FIG. 9, the method may include, but is not limited to, the following step 901:

[0149] In step 901, in response to the terminal device being configured for uplink multi-panel simultaneous transmission (STxMP) of multiple transmission / reception points (TRPs) corresponding to the PUSCH in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot that meets a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device being the maximum transmission power (Pcmax,p) for different panels, determining that the PHR reported by the terminal device is calculated according to at least one actual PH based on Pcmax,p corresponding to at least one panel, where p is a positive integer less than or equal to N, and N is the number of panels in the terminal device.

[0150] Optionally, if the PHR reported by the terminal device is one, the network device can determine that the one PHR is the actual PHR of the first panel calculated by the terminal device based on the first Pcmax,p corresponding to the first panel corresponding to the actual PUSCH transmission, where the actual PHR is associated with the transmission occasion corresponding to the PUSCH transmission in the first panel.

[0151] Alternatively, if there are two PHRs reported by the terminal device, the network device can determine that the two PHRs are an actual PHR of the first panel and a virtual PHR of the other panel, which are calculated by the terminal device based on the first Pcmax,p and a second Pcmax,p corresponding to the other panel, respectively, based on the actual PH and the virtual PH, where the actual PHR is associated with a transmission occasion corresponding to a PUSCH transmission in the first panel, and the virtual PHR is associated with a transmission occasion corresponding to a PUSCH transmission reference hypothesis in the other panel.

[0152] Here, the other panel may be any panel other than the first panel.

[0153] For example, if the first panel corresponding to the actually transmitted PUSCH is panel #1, the terminal device can calculate an actual PHR #1 based on Pcmax,p #1 corresponding to panel #1, and simultaneously calculate a virtual PHR #2 based on Pcmax,p #2 corresponding to panel #2, where PHR #1 is associated with a transmission occasion corresponding to the PUSCH transmission in panel #1, and PHR #2 is associated with a transmission occasion corresponding to the PUSCH transmission in panel #2, and reports PHR #1 and PHR #2 to the network device.

[0154] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR can be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0155] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR may be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

[0156] In the present disclosure, for a specific description of the PHR, please refer to the detailed description of any embodiment of the present disclosure, and a detailed description will be omitted here.

[0157] In the present disclosure, when a terminal device is configured for uplink STxMP of multiple TRPs corresponding to a PUSCH in the first transmission slot corresponding to the PUSCH carrying a MAC CE PHR report or in a slot that satisfies a timeline requirement, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, and the maximum power setting of the terminal device is Pcmax,p for the panel, the network device can determine that the PHR reported by the terminal device is calculated by the terminal device according to at least one actual PH based on Pcmax,p. This allows the network device to determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.

[0161] For example, a terminal device includes panel 1 and panel 2, where the first panel corresponding to actual PUSCH transmission is panel 1. When a network device receives a PHR reported by the terminal device, it can determine that the PHR is an actual power headroom PHI corresponding to panel 1 calculated and obtained by the terminal device according to an actual PH based on P, or PHI' corresponding to panel 1 calculated and obtained by the terminal device based on P corresponding to panel 1.

[0162] Alternatively, if the terminal device reports two PHRs, the network device may determine that the two PHRs include two actual PHRs of a first panel that the terminal device calculated and reported based on the Pcmax and a first Pcmax,p corresponding to the first panel corresponding to the actual PUSCH transmission. Alternatively, if the terminal device reports two PHRs, the network device may determine that the two PHRs include an actual PHR of a first panel that the terminal device calculated according to the actual PH based on the Pcmax and a virtual PHR of another panel that was calculated according to a virtual PH. Alternatively, if the terminal device reports two PHRs, the network device may further determine that the two PHRs include an actual PHR of the first panel that the terminal device calculated according to the actual PH based on the first Pcmax,p and a virtual PHR of the other panel that was calculated according to a virtual PH based on a second Pcmax,p corresponding to the other panel.

[0166] Alternatively, if the terminal device reports three PHRs, the network device can determine that the three PHRs include an actual PHR of the first panel that the terminal device calculates and reports according to the actual PH based on the first Pcmax,p, and two virtual PHRs corresponding to the other panel that are calculated respectively based on the Pcmax and a second Pcmax,p corresponding to the other panel.

[0167] Alternatively, if the terminal device reports three PHRs, the network device can determine that the three PHRs include an actual PHR of the first panel calculated by the terminal device according to the actual PH based on the Pcmax, and two virtual PHRs corresponding to the other panel calculated respectively based on the Pcmax and a second Pcmax,p corresponding to the other panel.

[0168] That is, referring to the above example, the three PHRs received by the network device may include PH1, PH1', and PH2, or may include PH1, PH1', and PH2', or may include PH1, PH2', and PH2, or may include PH1', PH2', and PH2, and the present disclosure is not limited in this regard.

[0170] For example, a terminal device includes panel 1 and panel 2, where the first panel corresponding to the actual PUSCH transmission is panel 1. If the terminal device reports three PHRs, it can be determined that the three PHRs include: PH1′ calculated and obtained by the terminal device based on Pcmax, p1, and the transmission power p1 of panel 1; PH2′ calculated and obtained based on Pcmax, p2, and the transmission power p2 calculated and obtained based on the transmission reference assumption of panel 2; and PH3 calculated and obtained based on Pcmax, p1, and p2 in a multi-panel transmission scheme, where PH3 may be an actual PH or a virtual PH.

[0171] Alternatively, if the terminal device reports four PHRs, the network device may determine that the four PHRs include two actual PHRs corresponding to the first panel calculated by the terminal device based on the Pcmax and a first Pcmax,p corresponding to the first panel, and two virtual PHRs corresponding to the other panel calculated by the terminal device based on the Pcmax and a second Pcmax,p corresponding to the other panel.

[0172] That is, referring to the above example, the four PHRs received by the network device include PH1, PH1', PH2 and PH2'.

[0173] Alternatively, if the terminal device reports five PHRs, the network device can determine that the five PHRs include two actual PHRs corresponding to the first panel calculated by the terminal device based on the Pcmax and a first Pcmax,p corresponding to the first panel, two virtual PHRs corresponding to the other panel calculated based on the Pcmax and a second Pcmax,p corresponding to the other panel, and one PHR corresponding to the terminal device calculated in combination with the Pcmax.

[0174] That is, referring to the example above, the five PHRs received by the network device may include PH1, PH1', PH2, PH2', and PH3.

[0175] Wherein, the actual PHR is associated with a transmission occasion corresponding to the PUSCH transmission in the first panel, and the virtual PHR is associated with a transmission occasion corresponding to the PUSCH transmission reference hypothesis in the other panel. In the present disclosure, for a specific description of the PHR, please refer to the detailed description of any embodiment of the present disclosure, and a detailed description will be omitted here.

[0176] Alternatively, the transmission of the PUSCH transmitted by the terminal device may be scheduled based on a single DCI using an SDM or FDM scheme to realize multi-panel uplink STxMP. Therefore, when the PUSCH is scheduled based on a single DCI, the reference format of the virtual PHR can be determined based on the transmission scheme of different panels when multiple panels simultaneously transmit one PUSCH using an SDM or FDM transmission scheme, or other predefined reference channel transmission scheme.

[0177] Alternatively, PUSCH transmission may be scheduled using an SDM scheme, an FDM scheme, or a TDM scheme based on multi-DCI to realize multi-panel uplink STxMP. Therefore, when PUSCH is transmitted using a coordinated transmission scheme scheduled based on multi-DCI, the reference format of the virtual PHR can be determined based on the PUSCH transmission scheme in different panels when multiple panels transmit two PUSCHs using an SDM, FDM, or TDM transmission scheme, or other predefined reference channel transmission scheme.

Thus, the network device can determine the PH of each panel based on the PHR reported by the multi-panel terminal device, perform accurate resource scheduling for each panel, and ensure the reliability of uplink transmission.
