DETAILED DESCRIPTION OF THE INVENTION

[0024] For ease of understanding, first, terms related to the present disclosure will be described.

[0025] 1. Power headroom report (PHR) PHR reflects the available power of the terminal device, that is, the power headroom. In the control of uplink transmission, it is necessary to measure the PHR and report it to the network device.

[0026] Here, what is related to multi-TRP uplink transmission is mainly the type 1 power headroom report. The report includes the power headroom and the maximum transmission power (Pcmax) in the component carrier where it is located. Pcmax is set by the network device for the terminal device. Since the network knows the encoding and modulation method corresponding to the power headroom report and the resource size of the terminal device used for transmission, it can determine an 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] The current PHR measurement mechanism can be divided into actual PHR or 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 a PHR based on a predefined PUSCH format and reports it to the network device, that is, reports the virtual PHR. The network device determines the bandwidth and transmission mode that the terminal device can transmit based on the power difference information of the terminal device.

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

[0029] 3. PUSCH PUSCH is used to carry data from the transport channel USCH. Sharing means that the same physical channel can be used by multiple terminal devices in a time-division manner, or it can be said that the channel has a short duration.

[0030] 4. Simultaneous transmission of multi panel (STxMP) By utilizing the cooperation between multiple panels to perform channel transmission / reception from multiple beams at multiple angles, various occlusion or blocking effects can be more appropriately overcome, and the robustness of the link connection can be ensured.

[0031] 5. Medium access control control element (MAC CE) The 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, first, a communication system to which the embodiments of the present disclosure are applied will be described below.

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

[0034] It should be noted that the technical solutions of the embodiments of the present disclosure are applicable to various communication systems. For example, a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems, etc.

[0035] In embodiments of the present disclosure, TRP11 and TRP12 are network-side entities for transmitting and receiving signals. For example, they may be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. Embodiments of the present disclosure do not limit the specific technologies and specific device forms used by network devices. The network device provided by embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. Using the CU-DU structure, the protocol layer of a network device, such as a base station, can be split. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed to the DU, and the CU centrally controls the DU. In the present disclosure, the TRP may be replaced by a Remote Radio Head or an antenna panel, etc.

[0036] The terminal device 13 in the embodiments of the present disclosure is an entity on the user side for transmitting and receiving signals, such as a mobile phone. The terminal device may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with a wireless transmission and reception function, 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 technologies and specific device forms used by the terminal device.

[0037] Note that the communication system described in the embodiments of the present disclosure is for more clearly explaining 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 those skilled in the art will understand, with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0038] In the present disclosure, since each panel of the terminal device has an independent power amplifier (PA) implementation structure, an independent power control process can be supported. Therefore, the maximum transmission power (Pcmax) can be set for the terminal device, or the maximum transmission power (Pcmax,p) corresponding to each panel can be set for each panel of the terminal device. Therefore, in the present disclosure, when the terminal device is set to uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmit-receive points (TRPs) corresponding to a PUSCH carrying a MAC CE PHR report, or in a slot that meets the timeline requirement, and the actual transmission of the PUSCH 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. Subsequently, the network device can determine the power headroom (PH) of the terminal device based on the PHR, perform resource scheduling for each panel based on the PH, thereby ensuring the reliability of uplink transmission.

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

[0040] Here, the embodiments of the present disclosure will be further described in combination with the drawings and specific embodiments.

[0041] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments that are consistent with the embodiments of the present disclosure. Rather, they are merely examples of apparatuses and methods that are consistent with some aspects of the present disclosure detailed in the appended claims.

[0042] The terms used in the embodiments of the present disclosure are used to describe specific embodiments and are not intended to limit the embodiments of the present disclosure. Unless otherwise clearly indicated in the context, the singular forms "a" and "the" used in the embodiments of the present disclosure and the appended claims are intended to include the plural forms. Note that the term "and / or" used herein refers to any or all possible combinations of one or more related listed items.

[0043] Depending on the context, the terms "when" and "in response to" used herein may be understood as "when...", "in the case of...", or "in response to the determined thing".

[0044] Embodiments of the present disclosure will be described in detail below, and examples thereof are shown in the accompanying drawings. In the drawings, the same or similar reference numerals refer to the same or similar elements throughout. The embodiments described below with reference to the drawings are merely exemplary and are intended to explain the present invention and not to limit the present invention.

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

[0046] In step 201, in a slot that meets the first transmission slot or 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, the uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmission and reception points (TRPs) is set for the PUSCH, and in response to the actual transmission of the PUSCH being a transmission from a single panel to a single TRP, at least one actual PH is calculated and a power headroom report (PHR) is reported according to 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 each transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, which is determined based on downlink control information (DCI). The slot that meets the timeline requirement may be a slot that meets the timeline requirement of the PHR report determined by the terminal device based on the protocol agreement or the instruction of the network device.

[0048] In the present disclosure, when a terminal device performs uplink transmission, in order to ensure the reliability of the uplink transmission, it is necessary to report the PHR to the network device. When the terminal device is in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, the uplink STxMP of a plurality of TRPs is set for the PUSCH, and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP, or in a slot that meets the timeline requirement, when the uplink STxMP of a plurality of TRPs is set for the PUSCH and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP, the PHR can be calculated and reported 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 encoding and modulation method of the terminal device at this time, accurately determine the bandwidth and transmission mode that the panel of the terminal device can transmit, thereby ensuring the reliability of uplink transmission.

[0050] Optionally, the maximum power setting of the terminal device may include the maximum transmission power (Pcmax) for the terminal device, or the maximum transmission power (Pcmax,p) for different panels, or may include both Pcmax and Pcmax,p, and the present disclosure is not limited thereto.

[0051] Here, the PHR may include the actual PH value calculated based on the maximum transmission power and the power actually transmitting the PUSCH, or may include a virtual PH value and a field for indicating the reference format of the virtual PH, etc. 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 of the virtual PH can indicate whether the reported PH value is determined based on actual transmission or based on the reference format. For example, when the value of the field for indicating the reference format of the PHR is set to 0, it indicates that the reported PH value is the actual PH value determined based on actual transmission, and when the value of the field for indicating the reference format of the PHR is set to 1, it indicates that the reported PH value is the virtual PH value determined based on the reference format.

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

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

[0054] Optionally, the transmission of the PUSCH transmitted by the terminal device can be scheduled to implement multi-panel uplink STxMP using a space division multiplexing (SDM) scheme or a frequency division multiplexing (FDM) scheme based on a single downlink control information (DCI). 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 method in different panels when multiple panels transmit one PUSCH simultaneously by the SDM or FDM transmission scheme, or other predefined reference channel transmission methods.

[0055] Optionally, PUSCH transmission can be scheduled based on multi-DCI using the SDM method, or the FDM method, or the time division multiplexing (TDM) method to achieve multi-panel uplink STxMP. Therefore, when PUSCH is transmitted in a cooperative transmission scheme scheduled based on multi-DCI, multiple panels can determine the reference format of the virtual PHR based on the PUSCH transmission method in different panels when transmitting two PUSCHs by the SDM, FDM or TDM transmission scheme, or other predefined reference channel transmission methods.

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

[0057] In the present disclosure, when the terminal device is configured for uplink STxMP of multiple TRPs corresponding to PUSCH in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot that meets the 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 the PHR according to at least one actual PH based on the maximum power setting. Thereby, 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.

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

[0059] In step 301, in a first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report by the terminal device, or in a slot satisfying a timeline requirement, the uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmit-receive points (TRP) is set corresponding to the PUSCH, and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP. In response to the maximum power setting of the terminal device being the maximum transmission power (Pcmax) for the terminal device, based on Pcmax, a PHR is calculated and reported based on at least one actual PH.

[0060] In the present disclosure, when the maximum power setting of the 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 a PHR according to at least one actual PH.

[0061] Optionally, 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 there are two panels in the terminal device, based on the average allocation rule, it can be determined that the maximum transmission power corresponding to each panel is 20 dBm.

[0062] Alternatively, the terminal device can determine the maximum transmission power corresponding to each panel by performing power allocation for Pcmax according to the dynamic allocation rule, where the dynamic allocation rule may be instructed by the network device or determined based on the protocol agreement. For example, the actual power output capabilities of the two panels of the terminal are different. Panel #2 is equipped with a larger power amplifier and supports a higher actual transmission power. In this case, it may be considered to perform allocation between the two panels in a dynamic manner based on the PA capability. For example, in panel #1, the PA supports 23 dBm, and in panel #2, the PA supports 26 dBm. The maximum transmission power of the terminal is set to 26 dBm. In this case, it may be considered to allocate the transmission power between the two panels in an average manner, or it may be considered to allocate between the two panels in a dynamic manner according to the PA capability. Alternatively, it may be considered to perform allocation between the two panels in a dynamic manner according to the PA capability. For example, the maximum transmission power of panel #2 accounts for 70% of the maximum transmission power of the terminal device. At this time, when the Pcmax of the terminal device is 26 dBm, based on the dynamic allocation rule, if panel #1 accounts for 30%, it can be determined that 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 set to the STxMP of multiple transmission and reception points (TRPs) for the PUSCH. That is, the network device schedules the terminal to transmit the PUSCH to one of the TRPs via the panel in this case. At this time, one 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 can calculate and report the actual PHR of the first panel corresponding to the actual PUSCH transmission according to the power allocation rule based on Pcmax. Here, the actual PHR is associated with the transmission occasion corresponding to the PUSCH transmission in the first panel.

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

[0066] For example, the terminal device can determine the maximum transmission power corresponding to each panel according to the power allocation rule based on Pcmax, calculate the actual PH corresponding to the first panel and the virtual PH corresponding to any one panel other than the first panel, and report the PHRs corresponding to the two panels respectively.

[0067] Optionally, the transmission of the PUSCH sent by the terminal device may be scheduled to implement the multi-panel uplink STxMP using the SDM method or the FDM method based on a single DCI. 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 method in different panels when multiple panels transmit one PUSCH simultaneously by the SDM or FDM transmission scheme, or other predefined reference channel transmission methods.

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

[0069] In this disclosure, for a detailed description of PHR, reference may be made to the detailed description of any embodiment of this disclosure, and the detailed description is omitted here.

[0070] In this disclosure, in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot satisfying the timeline requirement, when the uplink STxMP of multiple TRPs is set corresponding to the PUSCH and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP, the terminal device can calculate and report the PHR based on at least one actual PH based on the maximum power setting for the terminal device. Thereby, 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.

[0071] Referring to FIG. 4, FIG. 4 is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of this disclosure, and the method is 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, for the PUSCH, the uplink multi-panel simultaneous transmission (STxMP) of multiple transmission and reception points (TRP) is configured. The actual transmission of the PUSCH is a transmission from a single panel to a single TRP. In response to the maximum power setting of the terminal device being the maximum transmission power (Pcmax,p) for different panels, based on Pcmax,p corresponding to at least one panel, a PHR is calculated and reported based on at least one actual PH, 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, in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in a slot that meets the timeline requirement, for the PUSCH, the uplink STxMP of multiple TRP is configured. The actual transmission of the PUSCH is a transmission from a single panel to a single TRP. When the maximum power setting of the terminal device includes the 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 the actual PHR of the first panel based on the first Pcmax,p corresponding to the first panel corresponding to the actual transmission of the PUSCH, where the actual PHR is associated with the transmission occasion corresponding to the PUSCH transmission in the first panel.

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

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

[0077] For example, when the first panel corresponding to the actual PUSCH transmission is panel #1, the terminal device can calculate the actual PHR#1 according to the actual PH based on Pcmax,p#1 corresponding to panel #1, and at the same time, calculate the virtual PHR#2 according to the virtual PH based on Pcmax,p#2 corresponding to panel #2. Here, PHR#1 is associated with the transmission occasion corresponding to the PUSCH transmission in panel #1, PHR#2 is associated with the transmission occasion corresponding to the PUSCH transmission in panel #2, and PHR#1 and PHR#2 are reported to the network device.

[0078] Optionally, the transmission of the PUSCH sent by the terminal device may be scheduled using the SDM method or the FDM method based on a single DCI to achieve 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 method in different panels when multiple panels transmit one PUSCH simultaneously by the SDM or FDM transmission scheme, or other predefined reference channel transmission methods.

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

[0080] In the present disclosure, for the specific description of the PHR, reference is made to the detailed description of any embodiment of the present disclosure, and the detailed description is omitted here.

[0081] In the present disclosure, the terminal device is set to the uplink STxMP of multiple TRPs corresponding to the PUSCH in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, or in the slot that meets the timeline requirements. The actual transmission of the PUSCH is the transmission from a single panel to a single TRP. When the maximum power setting of the terminal device is the maximum transmission power (Pcmax,p) for different panels, based on the Pcmax,p corresponding to at least one panel, the PHR is calculated and reported based on at least one actual PH. Thereby, 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 the uplink transmission.

[0082] Referring to FIG. 5, FIG. 5 is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, and the method is 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 the PUSCH carrying the MAC CE PHR by the terminal device, or in the slot meeting the timeline requirement, the uplink STxMP of multiple TRPs is set for the PUSCH, and the actual transmission of the PUSCH is the transmission from a single panel to a single TRP. In response to the maximum power setting of the terminal device being Pcmax and Pcmax,p corresponding to each panel, the PHR is jointly calculated and reported according to at least one actual PH based on Pcmax and Pcmax,p.

[0084] Optionally, the terminal device can calculate and report the actual PHR of the first panel corresponding to the actual transmission of the PUSCH according to the actual PH based on the Pcmax. 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 corresponding to the first panel corresponding to the actual transmission of the PUSCH.

[0085] For example, the terminal device includes panel1 and panel2, where the first panel corresponding to the actual transmission of the PUSCH is panel1. Thus, the transmission power of panel1 is p1, the transmission power p2 is obtained by calculating using the transmission reference assumption of panel2, and based on Pcmax and Pcmax,p1, the actual power headroom corresponding to panel1 is obtained by calculating respectively according to the actual PH, and they are PH1 and PH1' respectively.

Therefore, the terminal device may report PH1 to the network device, or may report PH1' to the network device, and the present disclosure does not limit this.

[0086] Optionally, the terminal device may further calculate and report two actual PHRs of the first panel corresponding to the first Pcmax,p corresponding to the Pcmax and the actual PUSCH transmission. Alternatively, the terminal device may further calculate and report the 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 the virtual PHR of another panel according to the virtual PH. Alternatively, the terminal device may further calculate and report the actual PHR of the first panel according to the actual PH based on the first Pcmax,p, and calculate and report the virtual PHR of the other panel according to the virtual PH based on the 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 report PH1 and PH2 to the network device, or report PH1' and PH2' to the network device.

Based on Pcmax and Pcmax,p2, the virtual power headroom corresponding to panel2 is obtained by calculating according to the virtual PH respectively, and they are PH2 and PH2' respectively. 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 the first Pcmax,p corresponding to the first panel, and calculate and report the virtual PHR of the other panel based on the second Pcmax,p corresponding to the other 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 the 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 the second Pcmax,p corresponding to the other panel.

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

[0094] Optionally, the terminal device may further calculate and report the 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 respectively based on the Pcmax and the second Pcmax,p corresponding to the other panel.

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

[0097] For example, the terminal device includes panel1 and panel2. Here, the first panel corresponding to the actual PUSCH transmission is panel1, the transmission power of panel1 is p1, the transmission power p2 is obtained by calculating using the transmission reference assumption of panel2, and based on Pcmax and Pcmax,p1, the actual power headroom corresponding to panel1 is obtained by calculating according to the actual PH respectively, and they are PH1 and PH1′ respectively. Based on Pcmax and Pcmax,p2, the virtual power headroom corresponding to panel2 is obtained by calculating according to the virtual PH respectively, and they are PH2 and PH2′ respectively. Also, corresponding to p1 and p2, the terminal device may have a transmission power of p3 for the terminal device in the multi-panel transmission scheme, and PH3 can be obtained by calculating based on Pcmax. Here, PH3 may be an actual PH or a virtual PH. At this time, the terminal device may report PH1′, PH2′, and PH3 to the network device.

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

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

[0102] Here, each of the above actual PHRs is associated with a transmission occasion corresponding to PUSCH transmission in the first panel, and each virtual PHR is associated with a transmission occasion corresponding to a PUSCH transmission reference assumption in the other panel. In this disclosure, for a specific description of the PHR, reference is made to the detailed description of any embodiment of this disclosure, and the detailed description is omitted here.

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

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

[0105] In the present disclosure, in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report by the terminal device, or in the slot satisfying the timeline requirement, the uplink STxMP of multiple TRPs is set corresponding to the PUSCH, and the actual transmission of the PUSCH is the transmission from a single panel to a single TRP, and when the maximum power setting of the terminal device is Pcmax,p for the panel and Pcmax for the terminal device, at least the actual PHR can be calculated and reported according to the actual PH based on Pcmax,p. Thereby, 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 the uplink transmission.

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

[0107] In step 601, receive the indication information sent from the network device, where the indication information indicates the reporting method of the 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 indicate the method by which the terminal device reports the PHR based on the ability of the terminal device to report the PHR. For example, if the ability of the terminal device to report the PHR is to report four PHRs, the network device can indicate to the terminal device to report one PHR, or report two PHRs, or report three PHRs, or report four PHRs.

[0110] In step 602, in a slot that meets the first transmission slot or timeline requirement corresponding to the PUSCH carrying the MAC CE PHR report, the uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmit-receive points (TRP) is set corresponding to the PUSCH, and in response to the actual transmission of the PUSCH 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 the maximum power setting of the terminal device.

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

[0112] Alternatively, when the network device instructs the terminal device to report two PHRs, the terminal device can calculate and report the actual PHR2 corresponding to the first panel corresponding to the actual PUSCH transmission and the virtual PHR corresponding to another panel. Alternatively, the terminal device can calculate and report one actual PHR corresponding to the first panel based on the first Pcmax corresponding to the first panel, and calculate and report another actual PHR corresponding to the first panel according to the power allocation rule based on the Pcmax of the terminal device, 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 can calculate and report two actual PHRs corresponding to the first panel and one virtual PHR corresponding to another panel based on the Pcmax of the terminal device and the Pcmax,p corresponding to the first panel. Alternatively, one actual PHR corresponding to the first panel and two virtual PHRs corresponding to another panel can be reported, and the present disclosure is not limited thereto.

[0114] Alternatively, when 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 a detailed description of the maximum power setting of the terminal device and the determination and reporting of the virtual PHR, reference is made to the detailed description of any embodiment of the present disclosure, and the detailed description is omitted here.

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

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

[0118] In the present disclosure, after the terminal device receives the second indication information for instructing the reporting method of the PHR sent from the network device, 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 in the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report or in a slot that meets the timeline requirement, where the uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmit-receive points (TRPs) is set for the PUSCH, and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP. Thereby, 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 the uplink transmission.

[0119] Referring to FIG. 7, FIG. 7 is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, and the method 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 response to the uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmit-receive points (TRPs) being set for the physical uplink shared channel (PUSCH) carrying the media access control control element (MAC CE) PHR report in the first transmission slot corresponding to the PUSCH or in a slot that meets the timeline requirement, and the actual transmission of the PUSCH 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 the one with the smallest time-frequency domain position among each transmission slot corresponding to the PUSCH carrying the MAC CE PHR report determined based on downlink control information (DCI). The slot that meets the timeline requirement may be the slot determined by the terminal device based on the protocol agreement or the instruction of the network device and that meets the timeline requirement of the PHR report.

[0122] In the present disclosure, when the terminal device performs uplink transmission, in order to ensure the reliability of the uplink transmission, it is necessary to report the PHR to the network device. In the first transmission slot corresponding to the PUSCH carrying the MAC CE PHR report, the uplink STxMP of a plurality of TRPs is set corresponding to the PUSCH, and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP, or in the slot that meets the timeline requirement, when the uplink STxMP of a plurality of TRPs is set corresponding to the PUSCH and the actual transmission of the PUSCH 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 according to at least one actual PH based on the maximum power setting of the terminal device by 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 accurately determine the bandwidth and transmission mode that the panel of the terminal device can transmit based on the encoding and modulation method of the terminal device at this time, thereby ensuring the reliability of the uplink transmission.

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

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

[0126] Optionally, in response to the maximum power setting of the terminal device being the maximum transmission power (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 Pcmax.

[0127] Alternatively, in response to the maximum power setting of the terminal device being the maximum transmission power (Pcmax,p) for different panels, 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 thereto.

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

[0130] Optionally, the transmission of the PUSCH sent by the terminal device can be scheduled using the space division multiplexing (SDM) method or the frequency division multiplexing (FDM) method based on a single downlink control information (DCI) to realize the 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 method in different panels when multiple panels transmit one PUSCH simultaneously by the SDM or FDM transmission scheme, or other predefined reference channel transmission methods.

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

[0132] In the present disclosure, when the terminal device is configured for uplink STxMP of multiple TRPs corresponding to PUSCH in the first transmission slot carrying the MAC CE PHR report, or in a slot satisfying the 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, in a first transmission slot corresponding to a PUSCH in which a terminal device carries a MAC CE PHR report, or in a slot that meets the timeline requirement, the uplink STxMP of a plurality of TRPs is set corresponding to the PUSCH, and it is determined that the actual transmission of the PUSCH is a transmission from a single panel to a single TRP. Thereby, the network device can 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. Thereby, 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 the uplink transmission.

[0134] Referring to FIG. 8, FIG. 8 is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, and the method is 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 a first transmission slot corresponding to a PUSCH in which a terminal device carries a MAC CE PHR report, or in a slot that meets the timeline requirement, the uplink STxMP of a plurality of TRPs is set corresponding to the PUSCH, and the actual transmission of the PUSCH is a transmission from a single panel to a single TRP. In response to the maximum power setting of the terminal device being 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, when 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 the preset power allocation rule thereby.

[0137] Optionally, the terminal device may perform power allocation for Pcmax according to the average allocation rule, or the terminal device may perform the dynamic allocation rule to perform power allocation for Pcmax, where the dynamic allocation rule may be instructed by the network device or determined by the protocol agreement, and the present disclosure does not limit this.

[0138] Here, for the specific implementation form in which the terminal device performs power allocation based on the power allocation rule and calculates and reports the PHR, reference is made to the detailed description of any one of the embodiments of the present disclosure, and the detailed description is 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 the STxMP of multiple transmit-receive points (TRPs) for the PUSCH, that is, the terminal scheduled by the network device transmits PUSCH to one of the TRPs through the panel in this case. Therefore, one of the multiple panels in the terminal device at this time is transmitting the PUSCH. 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, when the terminal device reports one PHR, the network device can determine that the one PHR reported by the terminal device is the actual PHR of the first panel corresponding to the actual PUSCH transmission calculated according to the power allocation rule based on Pcmax by the terminal device. Here, the actual PHR is associated with the transmission occasion corresponding to the PUSCH transmission in the first panel.

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

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

[0143] For example, the terminal device determines the maximum transmission power corresponding to each panel according to the power allocation rule based on Pcmax, 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 PHRs corresponding to the two panels respectively.

[0144] Optionally, the transmission of PUSCH sent by a terminal device may be scheduled using the SDM method or the FDM method based on a single DCI 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 method in different panels when multiple panels simultaneously transmit one PUSCH using the SDM or FDM transmission scheme, or other predefined reference channel transmission methods.

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

[0146] In this disclosure, for a specific description of PHR, reference is made to the detailed description of any embodiment of this disclosure, and the detailed description is omitted here.

[0147] In the present disclosure, when a terminal device is configured with uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmission and reception points (TRPs) corresponding to a PUSCH in a first transmission slot carrying a MAC CE PHR report, or in a slot satisfying 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. Thereby, 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.

[0148] Referring to FIG. 9, FIG. 9 is a schematic flowchart of a power headroom reporting method based on multi-panel transmission provided by an embodiment of the present disclosure, and the method 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 a first transmission slot corresponding to a PUSCH carrying a MAC CE PHR report by a terminal device, or in a slot satisfying a timeline requirement, when the uplink multi-panel simultaneous transmission (STxMP) of a plurality of transmission and reception points (TRPs) is configured corresponding to the PUSCH, and the actual PUSCH transmission is a transmission from a single panel to a single TRP, and in response to the maximum power setting of the terminal device being the maximum transmission power (Pcmax,p) for different panels, it is determined 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, when there is one PHR reported by the terminal device, the network device can determine that the one PHR is the actual PHR of the first panel calculated based on the first Pcmax,p corresponding to the first panel to which the terminal device corresponds for the actual PUSCH transmission, where the actual PHR is associated with the transmission occasion corresponding to the PUSCH transmission in the first panel.

[0151] Or, when there are two PHRs reported by the terminal device, the network device can determine that the two PHRs are the actual PHR of the first panel and the virtual PHR of another panel calculated based on the actual PH and the virtual PH respectively, based on the first Pcmax,p corresponding to the terminal device and the second Pcmax,p corresponding to another panel.

[0170] For example, the terminal device includes panel1 and panel2, where the first panel corresponding to the actual PUSCH transmission is panel1. When the terminal device reports three PHRs, it can be determined that the three PHRs include PH1' obtained by the terminal device through calculation based on Pcmax,p1 and the transmission power p1 of panel1, PH2' obtained by calculation based on the transmission reference assumption of Pcmax,p2 and panel2 and the transmission power p2 obtained through calculation, and PH3 obtained by calculation based on Pcmax, p1, and p2 in the multi-panel transmission scheme, where PH3 may be an actual PH or a virtual PH.

[0176] Optionally, the transmission of the PUSCH transmitted by the terminal device may be scheduled using the SDM method or the FDM method based on a single DCI to realize the 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 method in different panels when multiple panels transmit one PUSCH simultaneously by the SDM or FDM transmission scheme, or other predefined reference channel transmission methods.

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