Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, apparatus, and storage medium for reporting a power headroom report.

Background Art

[0002] With the development of communication technologies, in order to guarantee coverage, it is necessary to use beam-based transmission and reception. When a network device (such as a base station) has multiple transmission reception points (TRPs), services can be provided to a terminal using multi-TRP / multi-panel (Multi-TRP / PANEL). The multi-TRP / PANEL of a network device is mainly applied to improve the coverage of the cell edge, provide a more balanced service quality within the service area, and use different methods to cooperate and transmit data between multi-TRP / PANELs. Considering from the perspective of the network form, arranging the network in the form of a large number of distributed access points plus baseband centralized processing is more advantageous for providing a balanced user experience speed, and the delay and signaling overhead caused by handoff are significantly reduced. By utilizing the cooperation between multi-TRP / PANELs and performing channel transmission / reception from multiple beams at multiple angles, various occlusion / blocking effects can be better solved, the robustness of the link connection can be guaranteed, and it is suitable for improving the transmission quality of ultra-reliable low-latency communication (URLLC) services and achieving reliability requirements.

[0003] In the R16 research stage, based on the application of multi-point coordinated transmission technology between downlink multi-TRP / PANEL, extended transmission was performed on the physical downlink shared channel (PDSCH). Since data transmission includes scheduling feedback of uplink channels and downlink channels, in the research of URLLC, only expanding the downlink data channel cannot guarantee service performance. Therefore, in the R17 research, the physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH) are continuously being expanded.

[0004] In the uplink PUSCH expansion based on R17 multi-TRP, the power control processes for PUSCH transmissions towards different TRPs are performed independently. In this way, for the terminal, the measured values of the power headroom (PH) transmitted by different TRPs are different. The measured values reported by the current power headroom report (PHR) need to clarify the specific reporting meaning of the available power in the protocol for use in precise uplink scheduling by the network device. Therefore, the expansion of the measurement of PHR by the terminal based on multi-TRP and the reporting process of the power headroom report (PHR reporting) are issues that require research.

[0073] In this specification, exemplary embodiments will be described in detail, and the examples are shown in the drawings. The following description relates to the drawings, and unless otherwise specified, the same reference numerals in different drawings indicate the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure detailed in the appended claims.

[0074] The PHR reporting method provided in the embodiments of the present disclosure can be applied to the wireless communication system shown in FIG. 1. Referring to FIG. 1, the wireless communication system includes a network device 20 and a terminal 10. The terminal is connected to the network device via wireless resources to transmit data. Here, data transmission is performed between the network device and the terminal based on a beam. Here, PUSCH uplink transmission can be extended between the network device and the terminal based on Multi-TRP.

[0075] It should be understood that the number of TRPs for the network device to perform data transmission with the terminal based on Multi-TRP may be one or more. In the wireless communication system shown in FIG. 1, the fact that the network device performs data transmission with the terminal based on TRP1, TRP2... TRPn is only an exemplary explanation and is not limiting.

[0076] The wireless communication system shown in FIG. 1 is merely an exemplary illustration, and the wireless communication system may further include other network devices, such as core network devices, wireless relay devices, and wireless repeater devices, etc., which are not depicted in FIG. 1. It should be understood that in the embodiments of the present disclosure, the number of network devices and terminals included in the wireless communication system is not limited.

[0077] Furthermore, it should be understood that the wireless communication system of the embodiments of the present disclosure is a network that provides a wireless communication function. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA (registered trademark)), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single Carrier FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance. Depending on factors such as the capacity, speed, and delay of different networks, the network can be divided into future evolved networks such as 2G (generation in English) networks, 3G networks, 4G networks, or 5G networks, also known as New Radio (NR) networks. For the convenience of description, in the present disclosure, the wireless communication network may sometimes be abbreviated as the network.

[0078] Furthermore, the network device according to the present disclosure may also be referred to as a wireless access device. The wireless access device may be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless return node, a transmission point (TP), or a transmission and reception point (TRP), etc., or may be a gNB in an NR system, or may be a component or a part of a device for setting up a base station, etc. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms used for the network device are not limited. In the present disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located within the coverage area (cell). Also, in the case of a vehicle-to-everything (V2X) communication system, the network device may be an in-vehicle device.

[0079] Furthermore, the terminal according to the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data communication to a user. For example, the terminal may be a handheld device with a wireless connection function, an in-vehicle device, etc. Currently, some terminals include mobile phones, customer premise equipment (CPE), pocket personal computers (PPC), palmtop computers, personal digital assistants (PDA), notebook computers, tablets, wearable devices, or in-vehicle devices, etc. Also, in the case of a vehicle-to-everything (V2X) communication system, the terminal device may be an in-vehicle device. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms used for the terminal are not limited.

[0080] In the present disclosure, data transmission is performed based on beams between the network device and the terminal. Here, between the network device and the terminal, uplink transmission can be extended based on Multi-TRP, that is, the terminal can extend uplink transmission using multi-point coordinated transmission technology in the transmission direction of multi-TRP.

[0081] The uplink extension scheme based on multi-TRP is mainly a PUCCH / PUSCH iterative transmission scheme based on R16. In the R16 PUCCH uplink transmission solution, inter-slot iterative transmission is supported. The R16 uplink transmission scheme supports an inter-slot iterative type A method and an iterative type B method that can be transmitted across slots for the scheduled and authorized PUSCH. Hereinafter, the transmission of the scheduled PUSCH and the PUSCH that does not need to be scheduled will be described respectively.

[0082] For scheduled PUSCH, there are mainly two uplink PUSCH time-domain repetition transmission extension methods, namely the iterative type A transmission method and the iterative type B transmission method, which are introduced by R16 respectively.

[0083] 1) Transmission method of PUSCH iterative type A Figure 2 is a diagram showing an example of PUSCH iterative type A. Referring to Figure 2, one PUSCH is transmitted in K consecutive slots, that is, K transmission occasions, starting from the S-th symbol in the starting slot, and each transmission occasion lasts for L symbols. Also, S + L cannot exceed the slot boundary. The PUSCH transmission of Rel-16 Slot Aggregation is not suitable for some situations where the delay requirement is very low and the reliability requirement is very high.

[0084] Here, for the transmission method of PUSCH iterative type A, the nominal repetition is the actual repetition.

[0085] 2) Transmission method of PUSCH iterative type B To reduce latency and improve reliability, Rel-16 supports a PUSCH iterative transmission scheme with Mini-slot as the unit and allows cross-slot PUSCH transmission, which can further reduce latency. In the time domain, one PUSCH starts transmitting from the S-th symbol a in the starting slot, and K nominal transmission occasions are transmitted continuously. Each nominal transmission occasion occupies L symbols continuously (back-to-back), and the transmission of S+L can cross the slot boundary. FIGS. 3A to 3C are diagrams showing examples of PUSCH repetition type B. FIG. 3A is an example of iterative transmission corresponding to K=2, L=4, and S=4. FIG. 3B is an example of iterative transmission corresponding to K=4, L=4, and S=4. FIG. 3C is an example of iterative transmission corresponding to K=1, L=14, and S=4.

[0086] As shown in FIGS. 5A to 5C, when the transmission occasion crosses the slot boundary, the transmission is re-divided, corresponding to the actual number of transmissions K', that is, the actual transmission occasion. For the entire transmission, the slot L*K represents the time window length of PUSCH transmission, and the DL symbols are discarded and not used for PUSCH transmission. The base station can indicate by SFI whether the quasi-static Flexible symbol is a dynamic uplink symbol or a dynamic downlink symbol. Therefore, the quasi-static Flexible symbol may be a symbol available for PUSCH or an unavailable symbol. If there are unavailable symbols among them, it is necessary to discard the unavailable symbols and then transmit with the remaining available symbols. The network device can also set an unavailable invalid symbol pattern for the terminal by signaling, that is, the terminal cannot transmit uplink data with the invalid symbols indicated by the signaling.

[0087] Here, the transmission parameters of PUSCH repetition type A and PUSCH repetition type B mentioned above are defined as shown in Table 1 below.

[0088]

Table 1

[0089] Furthermore, the uplink transmission of the terminal may be set to single-carrier transmission or multi-carrier transmission. Here, the settings corresponding to multi-carrier transmission include settings for performing Carrier Aggregation (CA). Here, when CA is set for the terminal, it may include a plurality of cells. For example, it may include one Primary Cell (PCell) and one or more Secondary Cells (SCells). In the current CA setting, there is one corresponding uplink carrier for one downlink carrier.

[0090] Furthermore, the uplink transmission settings may further include Dual Connectivity (DC) settings. In the DC setting, when CA is set for the terminal, it includes a plurality of cell groups of the Master Cell Group (MCG) and the Secondary Cell Group (SCG). Here, the MCG includes one PCell and zero or more SCells, and the SCG includes one PSCell and zero or more SCells.

[0091] Furthermore, the uplink transmission settings may further include a Supplement Uplink carrier (SUL carrier). In the 5G system, for one downlink carrier, two uplink carriers can be set, and one of them is a supplement uplink carrier that can be set to the PCell or SCell.

[0092] Regarding uplink transmission, for the network scheduling needs, it is necessary to report power headroom report (PHR reporting), and the PHR reflects the available power of the terminal, that is, the power headroom. The terminal triggers the reporting of the PHR according to the trigger conditions specified in the protocol. Here, the content reported in the PHR includes the maximum power that can be transmitted on each cell, the power headroom after the terminal transmits the uplink control channel (e.g., PUCCH) on each cell, the power headroom after the terminal transmits the uplink shared channel (e.g., PUSCH) on each cell, and the power headroom after the terminal transmits the uplink sounding channel (e.g., channel sounding reference signal (Sounding Reference Signal, SRS)) on each cell.

[0093] Here, the current PHR measurement mechanism can be divided into actual PHR measurement or virtual PHR measurement. When the terminal performs actual physical channel transmission, it reports the power headroom (actual PHR) after the physical channel is actually transmitted. For example, when PUSCH transmission is performed, the terminal reports the actual PHR to the network device. When the terminal does not perform actual physical channel transmission, it reports the power headroom (virtual PHR) after the physical channel reference (or virtual) is transmitted. For example, when PUSCH transmission is not performed, the terminal calculates one PHR, that is, the virtual PHR according to the pre-defined PUSCH format and gives it to the network device. The network determines the bandwidth and transmission mode that the terminal can transmit according to the power difference value information of the terminal.

[0094] Here, when reporting the PHR, it is reported based on the PHR media access control (MAC)-control element (CE).

[0095] Here, the reporting format of the PHR MAC-CE is as shown in FIG. 4. Here, the meanings of the related fields in the PHR MAC-CE format shown in FIG. 4 are as follows. -Ci: When the SCellIndex is set by an RRC message for one SCell, this field indicates whether the PH field of the SCell with SCellIndex i is reported. When the Ci field is set to "1", it indicates that the PH field of the SCell with SCellIndex i has been reported. When the Ci field is set to "0", it indicates that the PH field of the SCell with SCellIndex i has not been reported. -R: Reserved byte, set to "0". -V: This field indicates whether the reported PH value is based on actual transmission or the reference format. For Type1 PH, V = 0 indicates actual transmission on the PUSCH, and V = 1 indicates adopting the reference format of the PUSCH. For Type2 PH, V = 0 indicates actual transmission on the PUCCH, and V = 1 indicates adopting the reference format of the PUCCH. For Type3 PH, V = 0 indicates actual transmission on the SRS, and V = 1 indicates adopting the reference format of the SRS. Also, for Type1 PH, Type2 PH, and Type3 PH, V = 0 indicates that the P CMAX,c field is included, correspondingly indicating actual transmission on the PUSCH, and V = 1 indicates that the P CMAX,c field is not included, correspondingly indicating adopting the reference format of the PUSCH. -Power Headroom (PH): This field indicates the level of the power headroom. -P: This field indicates whether a power back-off mechanism is used for the current MAC entity. In the case of no power back-off, the P corresponding to a certain cell CMAX,cIf the fields have different values, the MAC entity is set to P = 1. - PCMAX,c: If the field exists, P for calculating the corresponding PH field value CMAX,c The numerical value, that is, it indicates the maximum transmit power of the cell calculated by the terminal and that can be transmitted.

[0096] Among them, the types of PH include Type 1 PH (PH type1,c (i) = P CMAX,c - P PUSCH,c (i)), Type 2 PH (PH type2,c (i) = P CMAX,c - P PUSCH,c (i) - P PUCCH,c (i)), and Type 3 PH (PH type3,c (i) = P CMAX,c - P SRS,c (i)).

[0097] Here, "i" related to each type of PH above is a certain subframe "i". Here, P PUSCH,c (i) is the transmit power of the uplink shared channel (PUSCH) obtained by the terminal through calculation. When the terminal actually transmits a signal, the value is determined based on the actually transmitted channel power. When the terminal does not actually transmit a signal, the value is determined based on the reference (or virtual) channel power. P PUCCH,c (i) is the transmit power of the uplink control channel (PUCCH) obtained by the terminal through calculation. When the terminal actually transmits a signal, the value is determined based on the actually transmitted channel power. When the terminal does not actually transmit a signal, the value is determined based on the reference (or virtual) channel power. P SRS,c (i) is the transmit power of the uplink sounding reference channel (SRS) obtained by the terminal through calculation. When the terminal actually transmits a signal, the value is determined based on the actually transmitted channel power. When the terminal does not actually transmit a signal, the value is determined based on the reference (or virtual) channel power.

[0098] In the uplink extension scheme based on multi-TRP, the PHR is transmitted only when the terminal is scheduled and transmitted on the Uplink Shared Channel (UL-SCH).

[0099] In the uplink transmission extension, the Type1 PH can be measured and the PHR can be reported to the network device. The PHR includes the power headroom and the maximum transmission power (P cmax ) on the component carrier where it is located, and P cmax is explicitly set by the network device. Since the network device can determine the encoding / modulation method corresponding to the PHR and the size of the resources used for the terminal's transmission, an effective combination of the modulation / coding scheme (Modulation and Coding Scheme, MCS) and the size of the allocated resources can be determined. Even when the PUSCH is not actually transmitted, the terminal can report the Type1 PH.

[0100] In the uplink PUSCH transmission extension based on the multi-TRP of R17, the power control processes for PUSCH transmissions for different TRPs are performed independently. In this way, for the terminal, the calculated values of the PHRs transmitted by different TRPs are different, and the terminal cannot determine how to measure and report the PHR corresponding to the multi-TRP. Therefore, when the network device also performs uplink scheduling, it cannot determine how to use which PHR among the different PHRs corresponding to the multi-TRP. For example, FIG. 5 shows a schematic diagram of the reporting process of the PHR media access control (MAC)-control element (CE) in carrier aggregation. In the PUSCH transmission process based on multi-TRP, when transmitting for a single TRP, the PH is calculated on carrier 1 and the PHR is reported. When transmitting for multi-TRP on carrier 2, when conforming to the PHR MAC-CE detimeline requirement, for the TRP1 direction (beam 1), the TO corresponding to #slot n is calculated to obtain the PH, but for the TRP2 (beam 2) direction, it cannot be determined whether to use slot n-1 or the TO corresponding to slot n+2 for the calculation of the PH. Therefore, for the uplink PUSCH transmission, PH measurement, and PHR reporting based on multi-TRP, in order to be used for the precise uplink scheduling of the network device, it is necessary to clarify the specific reporting meaning of the available power in the protocol.

[0101] In an embodiment of the present disclosure, when a terminal cooperatively transmits a PUSCH towards multiple TRPs, the terminal calculates and reports the PHR in one or more cooperative TRPs. In an embodiment of the present disclosure, when a terminal can perform uplink PUSCH transmission based on multiple TRPs, when the terminal is triggered by a network device to set and use a Type1 PHR report, when the timeline requirements for PHR calculation are met, each PHR scheduling reference of the multiple TRPs is realized, and the flow of PHR measurement reports is extended. By extending the PHR measurement report, PHR measurement reports for different transmission modes of PUSCH based on multi-TRP are further realized, thereby better supporting dynamic scheduling of different transmission methods, and realizing precise power control and more effective allocation and utilization of network resources.

[0102] It should be understood that the PHR reporting method provided in the embodiments of the present disclosure is also applicable to other PHR reporting types such as Type2 PHR and / or Type3 PHR. Hereinafter, the Type1 PHR report will be described as an example.

[0103] FIG. 6 is a flowchart of a PHR reporting method shown by an exemplary embodiment. The PHR reporting method may be executed alone or together with other embodiments of the present disclosure. As shown in FIG. 6, the PHR reporting method is used by a terminal and includes the following steps.

[0104] In step S11, in response to the terminal cooperatively transmitting a PUSCH towards multiple TRPs, the PHR in one or more cooperative TRPs is measured and reported.

[0105] In an embodiment of the present disclosure, the terminal's coordinated transmission of PUSCH towards multiple TRPs can be understood as the terminal performing uplink PUSCH transmission based on multi-TRP. When the terminal is triggered by a network device to report using a Type 1 PHR, under the condition of meeting the timeline requirements of PHR calculation, the PHR at one or more coordinated TRPs can be measured and reported, and the PHR scheduling reference for each of the multi-TRPs is realized.

[0106] In an embodiment of the present disclosure, with respect to whether the terminal actually transmits PUSCH, the terminal can be set to measure the virtual PH or the actual PH and report the PHR corresponding to the measurement of the virtual PH or the actual PH.

[0107] In one embodiment, in an embodiment of the present disclosure, when the terminal does not actually transmit PUSCH, it can measure the virtual PH.

[0108] FIG. 7 is a flowchart of a PHR reporting method shown by an exemplary embodiment. The PHR reporting method may be executed alone or together with other embodiments of the present disclosure. As shown in FIG. 7, the PHR reporting method is used for the terminal and includes step S21 and step S22.

[0109] In step S21, in response to the terminal not actually transmitting PUSCH, the terminal measures the virtual PH of the PUSCH based on calculating an assumption with a default or predefined reference format corresponding to a single TRP or multi-TRPs.

[0110] In an embodiment of the present disclosure, the reference format (which may also be referred to as the reference transmission format) can be obtained by measuring the PUSCH channel that does not need to be scheduled and is applied to the PH of the scheduled PUSCH.

[0111] Here, in the embodiments of the examples of the present disclosure, the virtual PH of PUSCH can be measured according to the calculation assumption of the default or predefined reference format corresponding to a single TRP (sTRP). In another embodiment of the examples of the present disclosure, the virtual PH of PUSCH can be measured according to the calculation assumption of the default or predefined reference format corresponding to a multi-TRP (mTRP).

[0112] In step S22, report a PHR including the virtual PH corresponding to PUSCH.

[0113] In the examples of the present disclosure, in response to the terminal not actually transmitting PUSCH, the virtual PH can be measured and a virtual PHR can be reported.

[0114] In one example, the examples of the present disclosure determine the PUSCH reference format based on the reference cooperation transmission method corresponding to the cooperative transmission of PUSCH towards a multi-TRP, and based on the determined PUSCH reference format, can report a PHR including the virtual PH corresponding to PUSCH.

[0115] In one example, in the examples of the present disclosure, based on a predefined or default cooperation transmission method such as time-division multiplexing (TDM) / space division multiplexing (SDM) / frequency division multiplexing (FDM), etc., the PUSCH reference format for the cooperative transmission of PUSCH towards a multi-TRP can be determined.

[0116] In the examples of the present disclosure, when the terminal actually transmits PUSCH, the actual PH can be measured.

[0117] FIG. 8 is a flowchart of a PHR reporting method shown by an exemplary embodiment, and the PHR reporting method may be executed alone or together with other embodiments of the present disclosure. As shown in FIG. 8, the PHR reporting method is used in a terminal and includes the following steps.

[0118] In step S31, in response to the terminal actually transmitting a PUSCH, measure the actual PH or virtual PH when the PUSCH is transmitted.

[0119] In step S32, report a PHR including a single PH or a plurality of PHs.

[0120] In an embodiment of the present disclosure, when the terminal measures the actual PH, based on whether the PUSCH carrying the PHR MAC-CE report and the actually scheduled PUSCH are located on the same carrier, determine the transmission occasion for measuring the actual PH, and the actual PH when the PUSCH is transmitted in the transmission occasion can be measured.

[0121] In one example, in an embodiment of the present disclosure, in response to the PUSCH carrying the PHR MAC-CE and the actually scheduled PUSCH being located on the same carrier, the transmission occasion can be determined using a predefined method. For example, the transmission occasion may be the first transmission occasion of the PUSCH transmission, or in the slot overlapping with the PUSCH carrying the PHR MAC-CE, the corresponding earliest transmission occasion for transmitting the scheduled PUSCH, or the transmission occasion corresponding to the earliest slot among one or more slots of the scheduled PUSCH that overlaps with the plurality of slot transmissions corresponding to the nominal transmission occasion of the PUSCH repetition type B carrying the PHR MAC-CE, or the corresponding plurality of transmission occasions in the plurality of slots of the scheduled PUSCH that overlaps with the plurality of slot transmissions corresponding to the nominal transmission occasion of the PUSCH repetition type B carrying the PHR MAC-CE, or one or more predefined transmission occasions before or after the slot reporting the PHR MAC-CE.

[0122] In another example, in an embodiment of the present disclosure, in response to the PUSCH carrying the PHR MAC-CE and the actually scheduled PUSCH being located in different carriers, and in the case of repeated transmission occasions, based on the subcarrier spacing corresponding to the active bandwidth part (BWP) of the carrier for reporting the PHR MAC-CE and the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, determine the transmission occasion for measuring the actual PH. For example, when the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE is smaller than the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, in the first transmission occasion of the PUSCH transmission, or in the slot overlapping with the PUSCH carrying the PHR MAC-CE, among the transmission occasions of the scheduled PUSCH, the earliest transmission occasion to be transmitted, or the transmission occasion corresponding to the earliest slot to be transmitted among one or more slots of the scheduled PUSCH that overlaps with the multiple transmission occasions of the scheduled PUSCH corresponding to the slot corresponding to the nominal transmission occasion of the PUSCH of PHR MAC-CE repetition type B, or the multiple slot transmissions corresponding to the nominal transmission occasion of the PUSCH of PHR MAC-CE repetition type B, or the transmission occasion corresponding to the earliest slot to be transmitted among one or more pre-defined transmission occasions before the slot carrying the PUSCH of PHR MAC-CE, or the corresponding multiple transmission occasions in the multiple slots of the scheduled PUSCH that overlap with the multiple slot transmissions corresponding to the nominal transmission occasion of the PUSCH of PHR MAC-CE, can be determined as the transmission occasion for measuring the actual PH.In another example, when the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE is equal to the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, the first transmission occasion of the PUSCH transmission, or the earliest transmission occasion among the transmission occasions overlapping with the slot for reporting the PHR MAC-CE, or the transmission occasion corresponding to the earliest slot to be transmitted among one or more slots of the scheduled PUSCH that overlaps with the nominal transmission occasion of the PUSCH repetition type B carrying the PHR MAC-CE, or the corresponding multiple transmission occasions in the multiple slots of the scheduled PUSCH that overlaps with the multiple slot transmissions corresponding to the nominal transmission occasion of the PUSCH repetition type B carrying the PHR MAC-CE, or one or more pre-defined transmission occasions before the slot for reporting the PHR MAC-CE can be determined as the transmission occasion for measuring the actual PH.

[0123] In an embodiment of the present disclosure, when the terminal transmits a PUSCH, it may schedule and transmit a single TRP or schedule and transmit multiple TRPs, and select a PHR for reporting one or more actual PHs based on whether the scheduled one is a single TRP or multiple TRPs.

[0124] FIG. 9 is a flowchart of a PHR reporting method shown by an exemplary embodiment. The PHR reporting method may be executed alone or together with other embodiments of the present disclosure. As shown in FIG. 9, the PHR reporting method is used by a terminal and includes the following steps.

[0125] In step S41, in response to the terminal actually scheduling and transmitting a single TRP to transmit a PUSCH, measure the actual PH when the PUSCH is transmitted at the specified transmission occasion.

[0126] In step S42, report a PHR including the actual PH corresponding to transmitting a PUSCH in the specified transmission occasion.

[0127] In an embodiment of the present disclosure, for the case where a single TRP is actually scheduled and a PUSCH is transmitted, a PHR including a single actual PH can be reported.

[0128] Furthermore, in an embodiment of the present disclosure, for the case where a single TRP is actually scheduled and a PUSCH is transmitted, the specified transmission occasion for measuring the actual PH mentioned above may include the following situations.

[0129] First, the PUSCH carrying the PHR MAC-CE and the actually scheduled PUSCH are located on the same carrier, and the specified transmission occasion is A: the first transmission occasion of the PUSCH transmission, and B: in the slot overlapping with the PUSCH carrying the PHR MAC-CE, the corresponding earliest transmission occasion for transmitting the scheduled PUSCH, and C: the transmission occasion corresponding to the earliest slot among one or more slots of the scheduled PUSCH that overlaps with a plurality of slot transmissions corresponding to the nominal transmission occasion of the PUSCH repetition type B carrying the PHR MAC-CE, and D: a plurality of transmission occasions corresponding to a plurality of slots of the scheduled PUSCH that overlaps with a plurality of slot transmissions corresponding to the nominal transmission occasion of the PUSCH repetition type B carrying the PHR MAC-CE, and E: one of one or more predefined transmission occasions before the slot reporting the PHR MAC-CE.

[0130] Second, when the PUSCH carrying the PHR MAC-CE report is located in a different carrier from the actually scheduled PUSCH, the specified transmission occasion can use the same slot as the actural PHR and PHR MAC-CE.

[0131] Here, when the PUSCH carrying the PHR MAC-CE report is located in a different carrier from the actually scheduled PUSCH, based on the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE and the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, the specified transmission occasion can be determined.

[0132] (1) In response to the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE being smaller than the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, the specified transmission occasion is A: The first transmission occasion of PUSCH transmission, and B: In the slot overlapping with the PUSCH carrying the PHR MAC-CE, the earliest transmission occasion among the transmission occasions of the scheduled PUSCH to be transmitted, and C: The multiple transmission occasions of the scheduled PUSCH corresponding to the slots overlapping with the PUSCH carrying the PHR MAC-CE, and D: The transmission occasion corresponding to the earliest slot to be transmitted among one or more slots of the scheduled PUSCH that overlaps with the multiple slot transmissions corresponding to the nominal transmission occasion of PUSCH repetition type B carrying the PHR MAC-CE, and E: The multiple transmission occasions corresponding to the multiple slots of the scheduled PUSCH that overlaps with the multiple slot transmissions corresponding to the nominal transmission occasion of PUSCH repetition type B carrying the PHR MAC-CE, and F: It is one of one or more pre-defined transmission occasions before the slot of the PUSCH carrying the PHR MAC-CE.

[0133] (2) In response to the sub-carrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE being equal to the sub-carrier spacing of the carrier where the transmitted PUSCH is located, the specified transmission occasion is A: The first transmission occasion of the PUSCH transmission, and B: The earliest transmission occasion among the transmission occasions overlapping with the slot for reporting the PHR MAC-CE, and C: The transmission occasion corresponding to the earliest slot to be transmitted among one or more slots of the scheduled PUSCH that overlaps with a plurality of slot transmissions corresponding to the nominal transmission occasion of the PUSCH of PHR MAC-CE repetition type B, and D: A plurality of transmission occasions corresponding to a plurality of slots of the scheduled PUSCH that overlaps with a plurality of slot transmissions corresponding to the nominal transmission occasion of the PUSCH of PHR MAC-CE repetition type B, and E: It is one of one or more pre-defined transmission occasions before the slot for reporting the PHR MAC-CE.

[0134] In an embodiment of the present disclosure, in the above case where the terminal actually schedules a single TRP to transmit the PUSCH, the actual PH is measured at the above-specified transmission occasion, and a PHR including a single PH is reported, that is, one PHR value is reported, corresponding to the single actually scheduled TRP.

[0135] In an embodiment of the present disclosure, when the terminal actually schedules multiple TRPs to transmit the PUSCH, multiple PHs can be measured at the specified transmission occasions of the multiple TRPs, and a PHR including a single PH or multiple PHs can be reported.

[0136] FIG. 10 is a flowchart of a PHR reporting method shown by an exemplary embodiment. The PHR reporting method may be executed alone or together with other embodiments of the present disclosure. As shown in FIG. 10, the PHR reporting method is used in a terminal and includes the following steps.

[0137] In step S51, in response to the terminal transmitting PUSCH in cooperation with a multi-TRP, a plurality of PHs in a designated transmission occasion of the multi-TRP are respectively measured.

[0138] In step S52, a PHR including a single PH or a plurality of PHs is reported.

[0139] In an embodiment of the present disclosure, when measuring a plurality of PHs in a designated transmission occasion of a multi-TRP, actual PHs may be measured or virtual PHs may be measured.

[0140] In an embodiment of the present disclosure, when measuring a plurality of PHs in a designated transmission occasion of a multi-TRP, different measurement methods can be used based on whether the PUSCH carrying the PHR MAC-CE report and the actually scheduled PUSCH are located on the same carrier.

[0141] (1) In response to the PUSCH carrying the PHR MAC-CE report and the actually scheduled PUSCH being on the same carrier, any one of Methods 1 to 6 can be used to respectively measure a plurality of PHs in a designated transmission occasion of the multi-TRP.

[0142] In Method 1, a plurality of actual PHs after the PUSCH is transmitted in the first transmission occasion corresponding to each of the multi-TRP are measured.

[0143] In method 2, in a slot overlapping with the PUSCH carrying the PHR MAC-CE, the earliest transmission occasion for transmission in the transmission occasion group corresponding to each TRP scheduling the PUSCH is used to measure a plurality of actual PHs.

[0144] In method 3, in a slot overlapping with a plurality of slot transmissions corresponding to the nominal transmission occasion of PUSCH repetition type B carrying the PHR MAC-CE, the earliest transmission occasion for transmission in each transmission occasion group corresponding to each TRP is used to measure a plurality of actual PHs.

[0145] In method 4, in a slot overlapping with a plurality of slot transmissions corresponding to the nominal transmission occasion of PUSCH repetition type B carrying the PHR MAC-CE, a plurality of actual PHs are measured at a plurality of transmission occasions in the transmission occasion group corresponding to each TRP.

[0146] In method 5, after PUSCH is transmitted at a predefined transmission occasion corresponding to each TRP before the slot for reporting PHR MAC-CE by multi-TRP, a plurality of actual PHs are respectively measured.

[0147] In method 6, after PUSCH is transmitted at a predefined transmission occasion corresponding to each TRP after the slot for reporting PHR MAC-CE by multi-TRP, a plurality of virtual PHs are respectively measured.

[0148] (2) In response to the PUSCH carrying the PHR MAC-CE and the actually scheduled PUSCH being located in different carriers, any one of the following methods 1 to 4 can be used to measure a plurality of PHs at the specified transmission occasions of multi-TRP respectively.

[0149] Here, for the sake of convenience of explanation, different TRPs of the multi-TRP are referred to as the first TRP and the second TRP. Here, the first TRP is one of the TRPs, and the second TRP is one or more other TRPs different from the first TRP among the multi-TRP.

[0150] In method 1, measure the actual PH after PUSCH is transmitted in the slot where PUSCH is transmitted and / or in the transmission occasion of the first TRP before the slot, and measure the actual PH after PUSCH is transmitted on the predefined slot of the second TRP on the slot where PUSCH is transmitted and / or before the slot.

[0151] In method 2, measure the actual PH after PUSCH is transmitted in the slot where PUSCH is transmitted and / or in the transmission occasion of the first TRP before the slot, and measure the actual PH after PUSCH is transmitted on the predefined slot of the second TRP on the slot where PUSCH is transmitted and / or before the slot. Set the PH of the second TRP measured before the slot where PUSCH is transmitted as the actual PH after PUSCH is transmitted on the predefined slot after the slot where PUSCH is transmitted.

[0152] In method 3, measure the actual PH after PUSCH is transmitted in the slot where PUSCH is transmitted and / or in the transmission occasion of the first TRP before the slot, and measure the virtual PH in the predefined slot of the second TRP after the slot where PUSCH is transmitted. Or, measure the actual PH of the second TRP after PUSCH is transmitted in the slot where PUSCH is transmitted, and measure the virtual PH in the predefined slot of the first TRP after the slot where PUSCH is transmitted.

[0153] In method 4, based on the subcarrier spacing corresponding to the active bandwidth part (BWP) of the carrier for reporting the PHR MAC-CE and the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, a plurality of PHs after the PUSCH is transmitted in a transmission occasion corresponding to multi-TRP are respectively measured.

[0154] Furthermore, in an embodiment of the present disclosure, when measuring a plurality of PHs after the PUSCH is transmitted in a transmission occasion corresponding to multi-TRP based on the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE and the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, different PH measurement methods are determined based on the magnitude between the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE and the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located.

[0155] In one embodiment, in response to the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE being smaller than the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, for the first TRP and the second TRP, measure the actual PH at which the PUSCH is transmitted in the earliest transmission occasion among a plurality of overlapping transmission occasions between different carriers, or measure the actual PH at which the PUSCH is transmitted in a plurality of overlapping transmission occasions between different carriers.

[0156] In another embodiment, in response to the subcarrier spacing corresponding to the active BWP of the carrier for reporting the PHR MAC-CE being equal to the subcarrier spacing corresponding to the active BWP of the carrier where the transmitted PUSCH is located, measure a plurality of actual PHs at which the PUSCH is transmitted in the first transmission occasion corresponding to multi-TRP.

[0157] In an embodiment of the present disclosure, based on the above method, after performing PH measurement, the PHR of a single PH or multiple PHs can be reported.

[0158] Here, in an embodiment of the present disclosure, when reporting the PHR of a single PH, the single PH is one of the following A to F.

[0159] A is the PH measured corresponding to the default or pre - defined first TRP. For example, it is the PHR corresponding to the power control parameter corresponding to the set with a small SRS resource set ID.

[0160] B is the PH measured corresponding to the TRP that uses the first transmission occasion by default or pre - defined.

[0161] C is the PH measured by the TRP for which the PHR selected by the terminal is lower than the PHR threshold. Here, by the terminal's self - selection, the PHR can select a relatively "bad" TRP calculation result and report it to the network.

[0162] D is the PH corresponding to the TRP determined based on the positive / negative value situation and the magnitude of the absolute value of the PH measured with multi - TRP.

[0163] Here, when both of the two PHR power values are actual PHR / virtual PHR, or one PHR power value is actual PHR and one PHR power value is virtual PHR, the D method is used to determine a single PH.

[0164] Here, in response to a single negative value existing in the PH measurement value measured by multi-TRP, the TRP corresponding to the single negative value is set as the TRP of a single PH in the PHR. In response to all the measured values of the PH measured by multi-TRP being negative values, the TRP with the largest absolute value of the PH measurement value is set as the TRP of a single PH in the PHR. In response to all the measured values of the PH measured by multi-TRP being positive values, the TRP with the smallest absolute value of the PH measurement value is set as the TRP of a single PH in the PHR.

[0165] E is the actual PH measured corresponding to the TRP that actually transmitted the PUSCH when both the actual PHR and the virtual PHR exist in the multi-TRP. For example, when one PHR power value is the actual PHR and one PHR power value is the virtual PHR, report preferentially according to the PHR corresponding to the actual PHR, and select and report an SRS resource set ID or other flag for distinguishing the TRP.

[0166] F is the PH measured at the TRP set or indicated by the network. That is, the terminal reports the PH according to the signaling indication on the network side.

[0167] In the embodiments of the present disclosure, in the above case where the terminal actually schedules multi-TRP to transmit the PUSCH, a plurality of PHs in the designated transmission occasion of the multi-TRP can be measured respectively, and a PHR including a single PH or a plurality of PHs can be reported, realizing the PHR measurement report for different transmission modes of the PUSCH based on multi-TRP, thereby better supporting the dynamic scheduling of different transmission methods, and realizing precise power control and more effective allocation and utilization of network resources.

[0168] In an embodiment of the present disclosure, the method for PH measurement and PHR reporting of a terminal may be set by a network device. The terminal performs PH measurement and PHR reporting according to the method set by the network device. The network device obtains the PHR in one or more coordinated TRPs reported by the terminal and performs power control in order to allocate and utilize network resources better.

[0169] Embodiments of the present disclosure provide a PHR reporting method applied to a network device based on the same concept.

[0170] FIG. 11 is a flowchart of a PHR reporting method shown by an exemplary embodiment. The PHR reporting method may be executed alone or together with other embodiments of the present disclosure. As shown in FIG. 11, the PHR reporting method is used for a terminal and includes the following steps.

[0171] In step S61, the terminal is set to transmit PUSCH in a coordinated manner towards multiple TRPs, and the terminal is set to measure and report the PHR in one or more coordinated TRPs.

[0172] In step S62, the PHR in one or more coordinated TRPs reported by the terminal is obtained.

[0173] In an embodiment of the present disclosure, the network device sets the terminal to measure and report the PHR in one or more coordinated TRPs, obtains the PHR in one or more coordinated TRPs reported by the terminal, and can realize PHR measurement reports for different transmission modes of PUSCH based on multi-TRP, thereby better supporting dynamic scheduling of different transmission methods, and realizing precise power control and more effective allocation and utilization of network resources.

[0174] Here, in the embodiments of the present disclosure, the embodiment in which the network device is set so that the terminal measures and reports the PHR in one or more cooperating TRPs corresponds to the implementation process of specifically executing the step in which the terminal measures and reports the PHR in one or more cooperating TRPs in the above embodiments. Therefore, since the specific setting process can refer to the related description shown in the above embodiments, the detailed description is omitted here.

[0175] It should be understood that the PHR reporting method provided in the embodiments of the present disclosure can also be applied to the implementation process in which the terminal and the network device realize PHR reporting through interaction. In the process of realizing PHR reporting through interaction between the network device and the terminal, since the network device and the terminal respectively have the related functions related to the execution of the above embodiments, the detailed description is omitted here.

[0176] Here, when the PHR reporting method according to the above embodiments is applied, the embodiments of the present disclosure may include an extended scheme for PH measurement and PHR reporting performed as follows.

[0177] (1) When the PUSCH is not actually transmitted, virtual PHR measurement is set. Alt.1: Measure and report using virtual PHR according to the default or predefined sTRP reference assumption calculation. Alt.2: Measure and report using virtual PHR according to the default or predefined mTRP reference assumption calculation.

[0178] Here, according to the coordinated transmission method based on the predefined or default such as TDM / SDM / FDM for the transmission of the PUSCH of the mTRP, the PUSCH reference format can be determined.

[0179] (2) When the PUSCH is actually transmitted using the sTRP, actual PH measurement is set. (1) The PHR MAC-CE and the PUSCH are located in the same CC including UL CA uplink carrier aggregation. When they are located in the same carrier, there are three alternatives, Alt.1 to Alt.3, for the method to be used. Alt.1: Use the actual PHR to measure the first transmission occasion TO and report one PHR value. Alt.2: Use the actual PHR to measure the pre-defined (e.g., the nearest one) transmission occasion TO before the slot in which the PHR MAC-CE is reported and report one PHR value. Alt.3: Measure the corresponding multiple transmission occasions TO in the multiple slots of the scheduled PUSCH that overlap with the multiple slot transmissions of PUSCH repetition type B carrying the PHR MAC-CE and report one PHR value, or measure one or more pre-defined transmission occasions TO before the slot in which the PHR MAC-CE is reported and report one PHR value.

[0180] (2) When considering UL CA but not located in the same carrier, use the actual PHR to measure the TO in the same slot as the PHR MAC-CE and measure one PHR value.

[0181] Here, when the SCS of the active BWP of the carrier where the PHR MAC-CE is located is smaller than the SCS of the active BWP of the carrier where the PUSCH is located, there are six alternatives, Alt.1 to Alt.6, for the method to be used. Alt.1: Calculate the first TO of the PUSCH and report one PHR. Alt.2: Calculate the first TO in the multiple overlapping TOs and report one PHR. Alt.3: Calculate the multiple TOs corresponding to the overlapping and report one PHR. Alt.4: Measure the pre-defined (e.g., the nearest one) transmission occasion TO before the slot in which the PHR MAC-CE is reported and report one PHR value. Measure the transmission occasion TO corresponding to the earliest slot to be transmitted among one or more slots of the scheduled PUSCH that overlaps with multiple slot transmissions of PUSCH repetition type B carrying the PHR MAC-CE, and report one PHR value. Alt.6: Measure the corresponding multiple transmission occasions TO in multiple slots of the scheduled PUSCH that overlaps with multiple slot transmissions of PUSCH repetition type B carrying the PHR MAC-CE, and report one PHR value.

[0182] Here, when the SCS of the active BWP of the carrier where the PHR MAC-CE is located is equal to the SCS of the active BWP of the carrier where the PUSCH is located, the used methods are Alt.1 to Alt.5. Alt.1: Calculate the first TO of the PUSCH and report one PHR. Alt.2: Calculate the first overlapping TO and report one PHR. Alt.3: Calculate the pre-defined (e.g., the nearest one) transmission occasion TO before the slot reporting the PHR MAC-CE, and report one PHR value. Alt.4: Measure the transmission occasion TO corresponding to the earliest slot to be transmitted among one or more slots of the scheduled PUSCH that overlaps with multiple slot transmissions of PUSCH repetition type B carrying the PHR MAC-CE, and report one PHR value. Alt.5: Measure the corresponding multiple transmission occasions TO in multiple slots of the scheduled PUSCH that overlaps with multiple slot transmissions of PUSCH repetition type B carrying the PHR MAC-CE, and report one PHR value.

[0183] (3) When the PUSCH is actually transmitted using mTRP, different measurement types are set. (1) When the PHR MAC-CE and the PUSCH are located in the same CC and the CA is also located in the same CC, the used methods are Alt.1 to Alt.4. Alt.1: Measure the first TO corresponding to different TRPs using the actual PHR respectively, and report one or more PHR values. Alt.2: Measure the pre-defined (e.g., the nearest one) transmission occasion TO corresponding to different TRPs before the slot reporting the PHR MAC-CE using the actual PHR respectively, and report one or more PHR values. Alt.3: In the slot overlapping with the PUSCH iterative type B transmission carrying the PHR MAC-CE, measure the earliest transmission occasion TO of each transmission occasion group corresponding to each TRP using the actual PHR respectively, and report one or more PHR values. Alt.4: In the slot overlapping with the PUSCH iterative type B transmission carrying the PHR MAC-CE, measure multiple transmission occasion TOs in each transmission occasion group corresponding to each TRP using the actual PHR respectively, and report one or more PHR values.

[0184] (2) When considering UL CA but not located in the same carrier, if the PHR MAC-CE is transmitted on slot #n of CC#1 and the PUSCH is transmitted on CC#2, the used methods are Alt.1 to Alt.5. Alt.1: Set it as the actual PHR. When the PUSCH corresponds to the TO of TRP1 (the same principle for TRP2) on slot #n, the measurement corresponding to the TRP is calculated and reported using the actual PHR. For the TO of TRP2, calculate the PHR using the pre-defined TO before slot #n using the actual PHR. Alternative 2: Set it as the actual PHR. When the PUSCH corresponds to the TO of TRP1 in slot #n, calculate and report using the actual PHR. For the TO of TRP2, calculate the PHR using the predefined TO before slot #n with the actual PHR. Considering that the PHR does not change significantly in one transmission, it is equivalent to sending the report at the TO after slot #n. Alternative 3: Set it as the actual + virtual PHR. When the PUSCH corresponds to the TO of TRP1 in slot #n, calculate and report using the actual PHR. For the TO of TRP2, calculate the PHR using the virtual PHR with the predefined TO after slot #n.

[0185] (3) Related processing of SCS Here, when the SCS of the active BWP of the carrier where the PHR MAC-CE is located is smaller than the SCS of the active BWP of the carrier where the PUSCH is located, calculate the PHR by measuring the first TO among multiple PUSCH TOs that overlap with the slot where the PHR MAC-CE is located. The same principle applies to the TO corresponding to another TRP. Or, calculate multiple PUSCH TOs that overlap with the slot where the PHR MAC-CE is located and measure the PHR. The same principle applies to the TO corresponding to another TRP.

[0186] Here, when the SCS of the active BWP of the carrier where the PHR MAC-CE is located is equal to the SCS of the active BWP of the carrier where the PUSCH is located, calculate the PHR by measuring the first TO.

[0187] Furthermore, when obtaining PHR measurement values corresponding to different TRPs through measurement, select one of the PHR values for reporting, and the following rules can be used. In Alternative 1, by default, use the PHR corresponding to the first TRP, for example, the PHR corresponding to the power control parameter corresponding to the set with a smaller SRS resource set ID. In Alt.2, use by default or pre - define the PHR calculated for the TRP corresponding to the first TO. In Alt.3, by the UE's own selection, the PHR selects the calculation result of the relatively "bad" TRP and reports it to the network. When both of the two PHR power values are actual PHR / virtual PHR, or when one PHR power value is actual PHR and one PHR power value is virtual PHR, denoted as PHR1 and PHR2 respectively, use the following method. In Method 1, if there is a negative value in the calculated value, give priority to reporting the PHR calculation result. In Method 2, if all are negative values, give priority to reporting the PHR calculation result with the larger absolute value. In Method 3, if all are positive values, give priority to reporting the PHR calculation result with the smaller absolute value. It can be considered that when the above - mentioned PHR reports the result, it also reports the corresponding SRI sort or SRS resource set ID or other flags for differentiating the TRP. In Alt.4, when one PHR power value is actual PHR and one PHR power value is virtual PHR, give priority to reporting the PHR corresponding to the actual PHR, and select and report other flags for differentiating the SRS resource set ID or TRP. In Alt.5, the reporting is instructed according to the signaling on the network side.

[0188] In the embodiments of the present disclosure, through the extended PHR measurement report, the PHR measurement report for different transmission modes of PUSCH based on multi - TRP can be realized, thereby better supporting the dynamic scheduling of different transmission methods, and realizing precise power control and more effective allocation and utilization of network resources.
