Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device, system and program product. Background Art

[0002] In order to improve the communication quality between the transmitter and the receiver and save energy, the transmitter can adjust the transmission power of the signal it sends. In some implementations, the transmitter can adjust its transmission power based on the path loss between the transmitter and the receiver to overcome the power consumption caused by interference during signal transmission and improve the signal quality of the receiver.

[0003] In some multi-transmission reception point (TRP) transmission scenarios, such as the DL single-TRP & UL multi-TRP scenarios, the terminal device needs to measure the corresponding path loss based on the signal sent by each TRP to the terminal device. However, in this scenario, there may be a TRP 2 that does not send a signal to the terminal device, which means that the terminal device cannot directly measure the path loss between the TRP 2 and the terminal device. Therefore, in this case, the difference between the path loss 1 between TRP 1 and the terminal device and the path loss 2 between TRP 2 and the terminal device can be sent to the terminal device by TRP 1 that can send a signal to the terminal device. Since the uplink path loss and downlink path loss of the terminal device relative to the same TRP can be considered equal, the terminal device can obtain the path loss between itself and TRP 2 based on the path loss measured by itself with TRP1 and the difference from TRP 1, so as to further adjust its transmission power when communicating with TRP 2.

[0004] In some implementations, path loss 1 can be the difference between the transmit power and the receive power of the uplink signal sent by the terminal device to TRP 1. For calculation accuracy, it is usually necessary to use the transmit power / receive power of multiple uplink signals for calculation. Among them, the transmit power of the uplink signal needs to be reported by the terminal device, but the existing power information reporting method has a large signaling overhead. Summary of the invention

[0005] The present application provides a communication method, device, system and program product, which can reduce signaling overhead.

[0006] In some implementations, when a terminal device reports power information of an uplink signal, it can only report power information of one signal at a time for one cell. When the terminal device needs to report multiple power information of multiple signals, multiple reports are required, resulting in large signaling overhead.

[0007] In a first aspect, a communication method is provided, which can be applied to a terminal device or a chip in a terminal device, the method comprising: determining a first message, the first message comprising multiple power information corresponding to multiple signals of each cell in at least one cell; and sending the first message.

[0008] In an embodiment of the present application, the terminal device can report the power information corresponding to multiple signals in each cell in at least one cell at one time through a first message. Compared with the related technology, in which the terminal device can only report the power information of one signal in one cell at a time, in a scenario where calculation based on multiple power information of multiple signals is required, the terminal device does not need to report multiple power information of multiple signals by reporting multiple times, which is conducive to saving signaling overhead.

[0009] Optionally, the at least one cell may refer to a cell to which the terminal device has accessed, and the number of the at least one cell may be one or more. When the number of the at least one cell is more than one, the first message may further include identifiers of cells corresponding to the multiple power information.

[0010] In combination with the first aspect, in certain implementations of the first aspect, the multiple signals include multiple first signals, the multiple first signals belong to the same signal set, and the multiple power information include multiple first power information corresponding to the multiple first signals; the multiple first power information is reported through the transmit power corresponding to the multiple first signals, and / or the maximum output power configured of the terminal device corresponding to the multiple first signals and the power margin of the terminal device corresponding to the multiple first signals.

[0011] In some possible implementations, the multiple signals also include multiple second signals, the multiple second signals belong to the same signal set, the multiple power information also include multiple second power information corresponding to the multiple second signals, and the signal set to which the multiple first signals belong is different from the signal set to which the multiple second signals belong.

[0012] In some implementations, there are multiple receiving devices in the communication scenario where the terminal device is located, for example, there are multiple TRPs. Signals sent by the terminal device to the same TRP and with the same signal type can be understood as belonging to the same signal set. The above-mentioned multiple first signals and multiple second signals can be understood as signals sent to different TRPs. The signal set to which the multiple first signals belong and the signal set to which the multiple second signals belong are different signal sets. The signal types between different signal sets can be the same or different, and this application does not limit this.

[0013] The above-mentioned multiple signals may include one or more groups of signals belonging to the same signal set. In this way, the receiving end can quickly and more quickly receive more comprehensive power information without waiting for multiple reports, which is beneficial to reducing the number of communications between the terminal device and the network side and saving energy consumption of both the sender and the receiver. The present application does not limit whether the signal types of these multiple groups of signals are the same.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the transmit power corresponding to the multiple first signals includes any one of the following: the transmit power of each signal in the multiple first signals; the i-th transmit power of the i-th signal in the multiple first signals, and the difference between the transmit power of each signal in the multiple first signals and the i-th transmit power, where i is a non-negative integer; or, the i-th transmit power, and the difference between the transmit powers corresponding to adjacent signals in the time domain in the multiple first signals.

[0015] In an embodiment of the present application, when the transmission power corresponding to multiple first signals includes the transmission power of each signal in the multiple first signals, the device receiving the first message can directly obtain the transmission power of each signal in the multiple first signals without performing complex calculations, which is beneficial to saving device computing power; when the transmission power corresponding to multiple first signals includes the i-th transmission power of the i-th signal in the multiple first signals, and the difference between the transmission power of each signal in the multiple first signals and the i-th transmission power, or the i-th transmission power and the difference between the transmission powers corresponding to adjacent signals in the time domain in the multiple first signals, since the data magnitude of the difference is smaller, compared with the method of directly reporting the transmission power of each signal, it is beneficial to save bits of the first message, and it is also beneficial to save transmission power consumption of both the sender and the receiver.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the maximum output power of the terminal device configuration corresponding to the multiple first signals includes any one of the following: the maximum output power of the terminal device configuration corresponding to any one of the multiple first signals; the maximum output power of the terminal device configuration corresponding to each of the multiple first signals; the i-th maximum output power of the terminal device configuration corresponding to the i-th signal among the multiple first signals, and the difference between the maximum output power of the terminal device configuration corresponding to each signal in the multiple first signals and the i-th maximum output power, where i is a non-negative integer; or, the i-th maximum output power and the difference between the maximum output powers of the terminal devices corresponding to adjacent signals in the time domain among the multiple first signals.

[0017] In combination with the first aspect, in certain implementations of the first aspect, the power margin of the terminal device corresponding to the multiple first signals includes any one of the following: the power margin of the terminal device corresponding to each signal in the multiple first signals; the i-th power margin of the terminal device corresponding to the i-th signal in the multiple first signals, and the difference between the power margin of the terminal device corresponding to each signal in the multiple first signals and the i-th power margin, where i is a non-negative integer; or, the i-th power margin, and the difference between the power margins of the terminal devices corresponding to adjacent signals in the time domain in the multiple first signals.

[0018] It should be understood that when the multiple first power information is reported through the maximum output power configured by the terminal device corresponding to the multiple first signals and the power margin of the terminal device corresponding to the multiple first signals, the multiple contents that may be included in the maximum output power configured by the terminal device corresponding to the multiple first signals and the multiple contents that may be included in the power margin of the terminal device corresponding to the multiple first signals can be arbitrarily combined, and the present application does not limit this.

[0019] When the maximum output power configured for the terminal device corresponding to each signal in multiple first signals is the same, the maximum output power configured for the terminal device corresponding to the multiple first signals includes the maximum output power configured for the terminal device corresponding to any one of the multiple first signals. That is, when the terminal device reports the power information corresponding to these signals, it can only report the maximum output power configured for one terminal device, which is beneficial to saving bits of the first message and also beneficial to saving communication overhead.

[0020] When the maximum output power of the terminal device configuration corresponding to each signal in multiple first signals is not exactly the same, the maximum output power of the terminal device configuration corresponding to each signal can be reported, which is helpful to improve the accuracy of the transmission power of each signal obtained by the opposite device.

[0021] Furthermore, by utilizing the difference in power margin or maximum output power, the bits occupied by the difference may be smaller than directly transmitting the power margin or maximum output power, which is beneficial to reducing the bits occupied by the first message, and is also beneficial to saving resources and reducing transmission overhead.

[0022] In combination with the first aspect, in certain implementations of the first aspect, there is a first correspondence between the multiple first power information and the resources of each of the multiple first signals, and the first correspondence is indicated by one or more of the following methods: protocol agreement, network equipment indication, included in the first message, or included in other messages sent by the terminal device.

[0023] In this way, the device receiving the first message can correspond each power information in the multiple first power information to the multiple first signals based on the first corresponding relationship, which is conducive to improving the accuracy of power-related calculations performed by the opposite device receiving the first message.

[0024] In combination with the first aspect, in certain implementations of the first aspect, when the first corresponding relationship is included in the first message, the first message also includes resource indexes of multiple first signals corresponding one-to-one to the multiple first power information.

[0025] This method of using the resource index to indicate the first corresponding relationship eliminates the need for the receiving end to perform complex calculations, which is beneficial for saving device computing power.

[0026] In combination with the first aspect, in certain implementations of the first aspect, the multiple power information includes power information corresponding to multiple signals sent by the terminal device to a first transmission receiving point TRP, and / or power information corresponding to multiple signals sent by the terminal device to a second TRP, and the first TRP and the second TRP are two different transmission receiving points in the same cell.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the first message also includes a first identifier and / or a second identifier, the first identifier is used to indicate power information related to the first TRP, and the second identifier is used to indicate power information related to the second TRP.

[0028] In this way, the receiving device can identify which TRP the multiple power information included in the first message is related to based on the first identifier and / or the second identifier, which is conducive to improving the accuracy of subsequent power-related calculations that may be performed.

[0029] In combination with the first aspect, in certain implementations of the first aspect, the multiple power information includes: transmission power difference information of the signals corresponding to the M1 signals sent by the terminal device to the first TRP and the M2 signals sent by the terminal device to the second TRP, M1 is equal to M2.

[0030] In combination with the first aspect, in some implementations of the first aspect, the reporting method of the transmit power difference information includes any one of the following:

[0031] M1 transmission power differences; wherein the jth transmission power difference △P(j) among the M1 transmission power differences is: the difference between the transmission power P1(j) of the jth signal among the M1 signals and the transmission power P2(j) of the jth signal among the M2 signals, j=0, 1, 2…M1-1. This is conducive to saving equipment computing power.

[0032] △P(j), the difference between each of the M1 transmit power differences and △P(j), or the difference between the transmit power differences of two pairs of signals adjacent in the time domain in the △P(j), M1 transmit power differences. In this way, it is beneficial to save the bits occupied by the first message and reduce the signaling overhead.

[0033] In combination with the first aspect, in certain implementations of the first aspect, there is a second correspondence between the resources of each signal in the M1 signals and / or the resources of each signal in the M2 signals and the transmit power difference information, and the second correspondence is indicated by one or more of the following methods: protocol agreement, network equipment indication, included in the first message, or included in other messages sent by the terminal device.

[0034] In this way, the device receiving the first message can correspond each of the multiple power information to the multiple signals based on the second corresponding relationship, thereby improving the accuracy of power-related calculations performed by the opposite device receiving the first message.

[0035] In combination with the first aspect, in certain implementations of the first aspect, the first message also includes: when the second correspondence is included in the first message, the resource index of the signal related to the first TRP corresponding to any power difference information, and / or, the resource index of the signal related to the second TRP corresponding to any power difference information.

The above-mentioned network devices can also be urban base stations, micro base stations, micro-micro base stations, femto-micro base stations, etc., and the present application does not limit this.

[0087] To facilitate understanding, some technical terms involved in this application are first introduced.

[0088] 1. Path loss: It refers to the loss of average signal power between the transmitter and the receiver due to the transmission distance and the transmission environment. It is a quantity related to the signal transmission distance, the transmission environment and the carrier frequency. Based on the path loss, the transmission power of the transmitter can be controlled.

[0089] It should be understood that path loss may also be referred to as path loss, path loss value, path loss amount or path loss information, etc., and this application does not make any specific limitation on this.

[0090] 2. Reference signal: It can refer to a known signal sent by the transmitter to the receiver for estimating or detecting wireless channel information. This wireless channel information can be very rough, such as the path loss of the wireless channel, etc. Based on the path loss information, the transmit power of the transmitter can be adjusted; the wireless channel information can also be very detailed, such as the accurate channel amplitude and phase information of the wireless channel in the time domain, frequency domain and spatial domain.

[0091] According to the Long Term Evolution LTE / NR protocol, at the physical layer, it includes uplink communication and downlink communication. Uplink communication includes transmission of uplink physical channels and uplink reference signals, and downlink communication includes transmission of downlink physical channels and downlink reference signals.

[0092] It should be understood that the transmission of an uplink physical channel can also be understood as transmitting information through an uplink physical channel, and the transmission of a downlink physical channel can also be understood as transmitting information through a downlink physical channel, and this application does not make any specific limitation on this.

[0093] 3. Physical uplink channels: may include but are not limited to: random access channel (PRACH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH).

[0094] 4. Uplink reference signal: may refer to a reference signal sent by a terminal device to a network device or a transmission and receiving point (TRP). Exemplarily, the uplink reference signal may include, but is not limited to: a channel sounding signal (SRS), a demodulation reference signal (DMRS) for an uplink control channel, a demodulation reference signal (PUSCH-DMRS) for an uplink data channel, an uplink phase noise tracking reference signal (PTRS), and an uplink positioning signal, etc.

[0095] 5. Physical downlink channel: may include but is not limited to: physical broadcast channel (PBCH), physical downlink control channel (PDCCH), and physical downlink shared channel (PDSCH).

[0096] 6. Downlink reference signal: may refer to a reference signal sent by a network device or TRP to a terminal device. For example, the downlink reference signal may include, but is not limited to: a downlink control channel demodulation reference signal (PDCCH-DMRS), a downlink data channel demodulation reference signal (PDSCH-DMRS), a phase noise tracking signal, a channel status information reference signal (CSI-RS), a time / frequency tracking reference signal (TRS), a cell reference signal (CRS), and an LTE / NR positioning signal (positioning RS).

[0097] It should be understood that the uplink reference signal and downlink reference signal, as well as the physical uplink channel and physical downlink channel shown above are only examples and should not constitute any limitation to the present application. The uplink reference signal or the downlink reference signal may also include more reference signals, and the present application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions. The physical uplink channel or the physical downlink channel may also include more physical channels, and the present application does not exclude the possibility of defining other physical channels in future protocols to achieve the same or similar functions.

[0098] 7. Transmission reception point (TRP): It can also be called a reception point. It can refer to a specific location or device in a communication system that is used to receive and process transmitted data. In a wireless communication system, TRP is usually used to receive signals transmitted from the transmitter and perform demodulation, decoding and other processing on the received signals to ensure that the data can be correctly transmitted to the target device. TRP can be a specific physical location, such as a base station or a receiving antenna, or a device, such as a modem or a receiver. In a communication system, the design and deployment of TRP is critical to ensure the quality of communication and the reliability of data transmission.

[0099] 8. Primary transmission reception point (PTRP): It can also be called primary TRP, etc. It refers to the main receiving point in the communication system, which is responsible for receiving and processing the main transmission data stream.

[0100] 9. Secondary transmission reception point (STRP): It can also be called auxiliary TRP, etc. It is usually an auxiliary receiving point in a communication system, used to assist in receiving data streams and transmit the received data streams to the primary transmission reception point.

[0101] In some implementations, STRP may not send downlink signals to achieve energy saving on the network side.

[0102] 10. Synchronization signal and PBCH Block (SSB): SSB can be used for cell search and synchronization. For example, by acquiring SSB, UE can synchronize time and frequency with the cell and detect the physical layer cell ID of the cell, namely the physical cell identifier (PCI). On the other hand, it can be used as a reference signal for UE to measure the cell. For example, by measuring SSB, UE can report the L1 downlink reference signal received power (RSRP) and SSB resource indicator (SS / PBCH blockresource indicator, SSBRI). The former is used for mobility management processes such as cell selection, reselection and switching, and the latter is used for initial beam management.

[0103] In NR, SSB consists of the primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the physical broadcast channel (PBCH).

[0104] Optionally, the SSB is also called an SS / PBCH block (SS / PBCH Block) or a synchronization signal block (synchronizationsignal block).

[0105] 11. Power headroom (PH): The power headroom can be understood as the difference between the maximum transmit power allowed by the UE and the transmit power of a certain signal. Taking the UE sending PUSCH as an example, the power headroom can be the difference between the maximum transmit power allowed by the UE and the currently evaluated PUSCH transmit power. It can be simply expressed by the formula PH =UEAllowedMaxTransPower – PuschPower, which indicates how much power the UE has left to use in addition to the transmit power currently used for PUSCH transmission.

[0106] To facilitate understanding of the embodiments of the present application, first Figure 1 A communication system applicable to an embodiment of the present application is described in detail.

[0107] Figure 1 Schematic diagram of a communication system 100 applied in an embodiment of the present application. The communication system 100 may include at least two TRPs, such as Figure 1 The TRP 110 and TRP 120 are shown. Among them, TRP 110 can be understood as a primary TRP, and TRP 120 can be understood as a secondary TRP. TRP 120 is within the coverage range 130 of TRP 110, so TRP 110 and TRP 120 can communicate with each other. And TRP 110 and TRP 120 can communicate with each other in a wired or wireless manner.

[0108] There is an intersection between the coverage range 140 of TRP 120 and the coverage range 130 of TRP 110, and compared with the coverage range 130 of TRP 110, the coverage range 140 of TRP 120 extends to a position farther from TRP 110. Therefore, the existence of the auxiliary TRP can improve the uplink throughput and effective coverage range, and the auxiliary TRP can also be understood as a location or device for performing radio frequency extension for the primary TRP.

[0109] In addition, the communication system 100 may also include at least one terminal device, such as Figure 1 The terminal device 150 is shown. The terminal device 150 is within the coverage range 130 of the TRP 110 and within the coverage range 140 of the TRP 120. Therefore, the terminal device 150 and the TRP 110 can communicate through a wireless link, and the terminal device 150 and the TRP 120 can also communicate through a wireless link.

[0110] Exemplarily, TRP 110 can act as a transmitter, terminal device 150 can act as a receiver, and TRP 110 sends downlink information to terminal device 150; or, TRP 110 can act as a receiver, terminal device 150 can act as a transmitter, and terminal device 150 sends uplink information to TRP 110.

[0111] Similarly, uplink communication and downlink communication can also be performed between TRP 120 and terminal device 150. However, in some application scenarios, in order to reduce the power consumption of the auxiliary TRP and achieve energy saving on the network side, the auxiliary TRP may not send downlink information to the terminal device, and the auxiliary TRP may receive uplink information from the terminal device. For example, TRP 120 can receive uplink information from terminal device 150, but TRP 120 does not send downlink information to terminal device 150.

[0112] Figure 1 Two TRPs and one terminal device are shown exemplarily. Optionally, the communication system 100 may also include more TRPs and / or more terminal devices. For example, the communication system 100 may also include more primary TRPs and / or more secondary TRPs. This application does not specifically limit this.

[0113] In addition, in some possible implementations, the TRP may also be replaced by a network device, such as a router, a base station, etc., and the primary TRP may be understood as a primary base station or a primary station, and the secondary TRP may be understood as a secondary base station or a secondary station. The terminal device 150 may be a mobile phone, a tablet computer, a smart bracelet, etc., which is not limited in the embodiments of the present application.

[0114] The above-mentioned communication equipment, such as Figure 1 The TRP 110, TRP 120 or terminal device 150 in the communication system may be configured with multiple antennas. The multiple antennas may include at least one transmitting antenna for sending signals and at least one receiving antenna for receiving signals. In addition, each communication device also additionally includes a transmitter chain and a receiver chain. It can be understood by those skilled in the art that they may include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, demodulators, demultiplexers or antennas, etc.). Therefore, TRP 110 and terminal device 140, as well as TRP 120 and terminal device 140, may communicate via multiple antenna technology.

[0115] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, but the embodiments of the present application are not limited thereto.

[0116] It should be understood that the method provided in the embodiment of the present application can be applicable to various communication systems including the 5G new radio (NR) system. Figure 1 The communication system 100 shown is only an example, and the present application does not limit the specific architecture of the applicable system, nor does it limit the number and form of various devices included in each communication system.

[0117] Wireless electronics propagate in a wireless environment with attenuation, which can also be called path loss. Therefore, there is path loss in the signal transmitted from the transmitter to the receiver. This path loss is usually related to the distance between the transmitter and the receiver, the transmission environment, and the carrier frequency. Therefore, the path loss between the transmitter and the receiver varies with the distance between the transmitter and the receiver, the transmission environment, or the carrier frequency.

[0118] The greater the path loss between the transmitter and the receiver, the greater the attenuation of the signal transmitted from the transmitter to the receiver. Therefore, the size of the path loss affects the signal quality of the signal received by the receiver. In order to make the signal quality of the signal received by the receiver meet the requirements, the transmitter can adjust the transmission power of the signal based on the path loss between the transmitter and the receiver. In this way, the power of the signal sent by the transmitter can overcome the power consumption of interference during the signal transmission process, so that the receiving power of the signal received by the receiver is larger.

[0119] Taking uplink communication as an example, the transmission power of uplink information sent by the terminal device can be based on the communication between the terminal device and the network device.

[0120] Exemplarily, the transmit power of the PUSCH sent by the terminal device is ( ) can be determined based on the following formula:

[0121] ,

[0122] in, c is the cell identifier, f is the carrier wave, b is the bandwidth (BWP), i For transmission timing, For the community c Carrier f BWP b PUSCH transmission timing on i The transmission power on is the maximum transmit power of the configured terminal device, is the open-loop operating point of PUSCH power control (or can also be understood as the expected received power), is the number of resource blocks (RBs) for PUSCH, μ is the subcarrier spacing, For the reference signal q dThe road loss measured on is the path loss compensation factor, is the transmission format compensation factor, It is the closed-loop power control adjustment value of PUSCH.

[0123] It should be understood that the above formula may also be referred to as a power control formula for sending a PUSCH or a power control formula corresponding to a PUSCH, etc. This application does not make any specific limitation on this.

[0124] It should also be understood that the transmission opportunity can be understood as a resource for transmitting uplink information, such as a time slot for transmitting uplink information or an orthogonal frequency division multiplexing (OFDM) symbol in a time slot.

[0125] It can be seen from the calculation formula of the above PUSCH transmission power that the determination of the PUSCH transmission power sent by the terminal device requires knowing the path loss between the terminal device and the network device.

[0126] It is worth noting that in the embodiments of the present application, only the calculation of the PUSCH transmit power is used as an example to reflect the importance of path loss. In fact, the calculation of the SRS transmit power, the PUCCH transmit power, etc. can also rely on the path loss, and the present application will not repeat the calculation process.

[0127] Exemplarily, in the communication system 100, TRP 110 can be understood as a primary TRP, and TRP 120 can be understood as a secondary TRP. The primary TRP can send a downlink signal to a terminal device, and the terminal device can measure the path loss between the terminal device and the primary TRP based on the downlink signal from the primary TRP. However, in the case where the secondary TRP cannot send downlink information to the terminal device, the terminal device cannot measure the path loss between the terminal device and the secondary TRP based on the downlink signal from the secondary TRP.

[0128] In this case, the terminal device can currently determine the path loss between it and the auxiliary TRP through the following method.

[0129] It should be understood that for simplicity, the path loss between the terminal device and the primary TRP is referred to as path loss 1 (PL1), and the path loss between the terminal device and the secondary TRP is referred to as path loss 2 (PL2). The terminal device can determine path loss 2 by the following method.

[0130] It is known that the terminal device can obtain path loss 1 based on the downlink signal measurement from the main TRP. In this way, when the terminal device can determine the difference between path loss 1 and path loss 2, the terminal device can determine path loss 2 based on path loss 1 and the difference. For example, path loss 2 (PL2) can satisfy the following formula:

[0131] PL2=PL offset +PL1, where PL1 is path loss 1, PL offset is the difference between path loss 1 and path loss 2. Therefore, path loss 2 is the sum of path loss 1 and the difference.

[0132] It can be seen that the key for the terminal device to determine the path loss 2 is to obtain PL offset , and determine PL offset The premise is that the main TRP obtains path loss 1 (or the auxiliary TRP obtains path loss 2). Taking the calculation of the main TRP to obtain path loss 1 as an example, the main TRP can calculate the received power P of the uplink signal from the terminal device. Rx1 , transmit power P Tx1 , through the formula PL1=P Tx1 -P Rx1 The path loss 1 is calculated.

[0133] Among them, the received power P Rx1 It can be measured by multiple downlink signals sent by the main TRP to the terminal device. For example, the estimated value of the received power Fn = (1 – a)*Fn-1 + a*Mn, where Mn is the received power measured on the current signal, Fn is the measurement result after L3 filtering, Fn-1 is the measurement result after L3 filtering of the previous signal, and F0 = M1. a = 1 / 2(k / 4) is the filter coefficient, where k is configured by the network side. In some implementations, the received power P Rx1 = Fn. It should be understood that the terminal device can also calculate the downlink signal receiving power in a similar manner.

[0134] In some implementations, the transmit power P Tx1 It can be obtained through the power headroom report (PHR) reported by the terminal device. Figure 2 and Figure 3 Two reporting methods of PHR in related technologies are described.

[0135] Figure 2 The signaling structure of a single entry power headroom report medium access control layer control element (singleentry PHR MAC CE) is exemplarily shown.

[0136] like Figure 2 As shown in the figure, the single entry PHR MAC CE can only carry the power margin PH (Type 1, PCell) of the uplink carrier of the primary cell (PCell) and its corresponding maximum transmit power P of the terminal device. CMAX,f,cThe "R" in the figure can be understood as a reserved bit, and the "P" can be used to indicate whether power backoff is set.

[0137] Figure 3 The signaling structure of a multiple entry power headroom report medium access control layer control element (multiple entry PHR MAC CE) is exemplarily shown.

[0138] like Figure 3 As shown, the multiple entry PHR MAC CE can carry the power headroom on the uplink carriers of multiple serving cells (for example Figure 3 ) and the maximum transmit power of the corresponding terminal device (e.g. Figure 3 P shown in CMAX,f,c 1~P CMAX,f,c m). The R field in the figure can be understood as a reserved bit, the P field can be used to indicate whether the power backoff that meets the Maximum Permissible Exposure (MPE) requirement is set, and the V field can be used to indicate whether the PH value is based on actual signal transmission or calculated based on the signal reference format. k The PH field may be used to indicate whether there is a PH field for the kth serving cell.

[0139] Each PH is obtained based on a signal or a transmission occasion of a signal in the cell.

[0140] It can be seen that neither the single entry PHR MAC CE nor the multiple entry PHR MAC CE can report the power margin of multiple signals in a cell and / or the maximum transmit power of multiple signals in a cell, which means that each time the PHR is sent, the network side can only obtain the power information of one signal in a cell.

[0141] However, in some implementations, in order to ensure the accuracy of the path loss measurement, the main TRP (or auxiliary TRP) generally needs to average the transmit power and / or receive power of multiple signals from the terminal device for path loss calculation, or obtain the path loss corresponding to each signal for multiple signals and then average them (other processing methods may also be used). However, the terminal device may perform power control on multiple uplink signals, which means that the transmit power of multiple uplink signals used for path loss calculation is likely to be different. For this reason, it is necessary for the terminal device to report the transmit power of these signals to the network side. However, if the PHR reporting method in the relevant technology is used, each PHR can only report the power information of one signal at a time, then the terminal device needs to send multiple PHRs to report the power information rate of multiple signals to the network side, which brings a large signaling overhead.

[0142] In view of this, the present application provides a communication method, apparatus, system and program product, which can enable a terminal device to carry multiple power information corresponding to multiple signals of each cell in at least one cell to which the terminal device is connected in one report, so as to reduce signaling overhead.

[0143] It is worth noting that the calculation of the path loss in the above text is only an application example of the power information reported by the terminal device. The method provided in the embodiment of the present application is also applicable to other power-related calculations. The above example does not constitute a specific limitation on the application scenario of the present application.

[0144] Combine the following Figures 4 to 7 The communication method of the present application is described in detail. The embodiments shown in the present application illustrate the communication method and device provided by the present application from the perspective of device interaction. The specific form and quantity of each device shown therein are only examples and should not constitute any limitation on the implementation of the method provided by the present application. Below, taking the terminal device and the first TRP as the execution subject as an example, the communication method and device of the embodiment of the present application are described in detail.

[0145] It should be understood that the terminal device can be the terminal device itself, or a chip, chip system or processor that supports the terminal device to implement the communication method, or a logic module or software that can implement all or part of the functions of the terminal device. The first TRP can be the first TRP itself, or a chip, chip system or processor that supports the first TRP to implement the communication method, or a logic module or software that can implement all or part of the functions of the first TRP. This application does not make specific restrictions on this.

[0146] It should be noted that in the embodiment of the present application, the main TRP and the auxiliary TRP can be understood as network devices, the main TRP described above can also be replaced by the first TRP, and the auxiliary TRP can also be replaced by the second TRP, which will not be repeated below.

[0147] Figure 4 The flowchart of a communication method 400 provided in an embodiment of the present application is shown in FIG. The method 400 may be applicable to the communication system 100 .

[0148] The method 400 may include the following steps:

[0149] S401. A terminal device determines a first message, where the first message includes multiple power information corresponding to multiple signals of each cell in at least one cell.

[0150] S402. The terminal device sends a first message to the first TRP; correspondingly, the first TRP receives the first message.

[0151] S403. The first TRP is calculated using multiple power information.

[0152] Optionally, the terminal device can access at least one cell, and the at least one cell may be one or more cells included in the same base station, or multiple cells corresponding to different base stations, or a carrier aggregation (CA) cell. The at least one cell may include a primary cell (PCell), a primary secondary cell (PSCell) or a secondary cell (SCell), etc. This application does not make any specific limitations on this.

[0153] Optionally, the multiple signals may refer to uplink signals that have been sent or are about to be sent by the terminal device, which may be uplink reference signals, such as SRS, DMRS, PUSCH-DMRS, or PTRS, or uplink channels, such as PRACH, PUCCH, or PUSCH, etc. This application does not make any specific limitations on this.

[0154] Optionally, after receiving the first message from the terminal device, the first TRP can use the multiple power information included in the first message to estimate the uplink path loss, perform downlink power control calculations or other service quality optimization calculations, etc. The present application does not specifically limit the calculations that the first TRP can perform based on multiple power information.

[0155] In an embodiment of the present application, the terminal device can report the power information corresponding to multiple signals in each cell in at least one cell at one time through a first message. Compared with the method in the related art in which the terminal device can only report the power information of one signal in one cell at a time, in a scenario where calculation is required based on multiple power information corresponding to multiple signals in the same cell, the terminal device does not need to report multiple power information of multiple signals by reporting multiple times, which is beneficial to saving the signaling overhead of the terminal device and / or the first TRP.

[0156] Optionally, when there are multiple cells, the first message may further include identifiers of cells corresponding to multiple power information. The present application does not specifically limit the specific identifier used for the cell.

[0157] Optionally, scenarios requiring calculation based on multiple power information of multiple signals may include, for example, the first TRP described above (which can be understood as the main TRP described above) calculating the path loss 1 between it and the terminal device and / or the second TRP (which can be understood as the auxiliary TRP described above) calculating the path loss 2 between it and the terminal device, but the present application is not limited to this application scenario.

[0158] Furthermore, in a scenario where calculations need to be performed based on multiple power information of multiple signals, the first TRP described above can directly or indirectly obtain multiple transmission powers of multiple signals based on multiple power information of multiple signals, and subtract the multiple transmission powers of the multiple signals from their respective receiving powers to obtain the path loss obtained for each signal between the terminal device and the first TRP, and / or, obtain the path loss obtained for each signal between the terminal device and the second TRP. Then, illustratively, the path loss 1 between the terminal device and the first TRP can be the average value of the path loss obtained for each signal among the multiple signals sent by the terminal device to the first TRP.

[0159] The multiple signals described in the embodiments of the present application can be understood as multiple signal transmission occasions. When there are multiple signals occupying different frequency domain resources in the same time domain, these multiple signals occupying different frequency domain resources can be understood as sharing a signal transmission opportunity. When the terminal device reports power information, these multiple signals occupying different frequency domain resources can correspond to the same power information.

[0160] In one possible implementation, the multiple signals described in the above method 400 may be all or part of the signals sent by the terminal device, the multiple power information may be the power information of all or part of the signals sent by the terminal device, and the number of multiple signals may be agreed upon by the protocol, indicated by the network device, or indicated by other terminal devices, and this application does not limit this.

[0161] As an optional embodiment, the multiple signals in the above method 400 include multiple first signals, the multiple first signals belong to the same signal set, and the multiple power information include multiple first power information corresponding to the multiple first signals. Furthermore, the multiple signals may also include multiple second signals, the multiple second signals belong to the same signal set, and the multiple power information also includes multiple second power information corresponding to the multiple second signals, and the signal set to which the multiple first signals belong is different from the signal set to which the multiple second signals belong. In other words, the multiple signals described in the above method 400 may include signals belonging to multiple different signal sets, and each signal set in the multiple different signal sets may include multiple signals, and the signals belonging to the same set have the same signal type, and the signal types of the signals in different signal sets may be the same or different, and the present application does not limit this.

[0162] It should be understood that the reporting methods of the multiple first power information and the multiple second power information may be similar. The following takes the reporting of the multiple first power information as an example to describe in detail the various possible reporting methods.

[0163] In a possible implementation, multiple first power information can be reported through the maximum output power (UE configured maximum output power) configured by the terminal device corresponding to the multiple first signals and the power margin of the terminal device corresponding to the multiple first signals.

[0164] Among them, the maximum output power of the terminal device configuration corresponding to multiple first signals includes any one of the following: 1) the maximum output power of the terminal device configuration corresponding to any one of the multiple first signals; 2) the maximum output power of the terminal device configuration corresponding to each of the multiple first signals; 3) the i-th maximum output power of the terminal device configuration corresponding to the i-th signal among the multiple first signals, and the difference between the maximum output power of the terminal device configuration corresponding to each signal in the multiple first signals and the i-th maximum output power, where i is a non-negative integer; or, 4) the i-th maximum output power, and the difference between the maximum output powers of the terminal devices corresponding to adjacent signals in the time domain among the multiple first signals.

[0165] The power margin of the terminal device corresponding to multiple first signals includes any one of the following: a) the power margin of the terminal device corresponding to each signal in the multiple first signals; b) the i-th power margin of the terminal device corresponding to the i-th signal in the multiple first signals, and the difference between the power margin of the terminal device corresponding to each signal in the multiple first signals and the i-th power margin, where i is a non-negative integer; or, c) the i-th power margin, and the difference between the power margins of the terminal devices corresponding to each of the adjacent signals in the time domain in the multiple first signals.

[0166] It should be understood that when multiple first power information is reported through the maximum output power configured by the terminal device corresponding to multiple first signals and the power margin of the terminal device corresponding to the multiple first signals, the maximum output power configured by the terminal device corresponding to the above-mentioned multiple first signals includes any one of 1), 2), 3) or 4), which can be freely combined with any one of a), b) or c) included in the power margin of the terminal device corresponding to the multiple first signals, and there is no limitation on what the maximum output power configured by the terminal device corresponding to the multiple first signals and the power margin of the terminal device corresponding to the multiple first signals specifically include.

[0167] In a possible implementation, when the maximum output powers of the terminal devices corresponding to the multiple first signals are the same, the content of the multiple first power information may be reported in the following manner:

[0168] Mode 1: A combination of 1) and a) above. That is, the multiple first power information includes: the maximum output power configured by the terminal device corresponding to any one of the multiple first signals, and the power margin of the terminal device corresponding to each of the multiple first signals.

[0169] It should be understood that when a terminal device reports a maximum output power configured for the terminal device, it can be understood that the maximum output powers configured for the terminal devices corresponding to multiple first information are all the same.

[0170] For each first signal, the corresponding first power information includes the maximum output power configured by the terminal device and the power margin of the corresponding terminal device. The transmission power may be the difference between the maximum output power configured by the terminal device and the power margin of the corresponding terminal device. The first TRP may be based on the maximum output power configured by a terminal device reported by the terminal device and the power margin of the terminal device corresponding to each of the multiple signals, to obtain the transmission power of each of the multiple signals.

[0171] Mode 2: A combination of 1) and b) above. That is, the multiple first power information includes: the maximum output power configured by the terminal device corresponding to any one of the multiple first signals, the i-th power margin of the terminal device corresponding to the i-th signal in the multiple first signals, and the difference between the power margin of the terminal device corresponding to each signal in the multiple first signals and the i-th power margin, where i is a non-negative integer.

[0172] Exemplarily, the number of the plurality of first signals is M, where M is a non-negative integer. The i-th power margin of the terminal device corresponding to the i-th signal among the plurality of first signals can be recorded as PH(i), the power margin of the terminal device corresponding to any one of the plurality of first signals can be recorded as PH(x), and the difference between the power margin of the terminal device corresponding to any one of the plurality of first signals and the i-th power margin can be recorded as PH diff (x), PH diff The calculation formula for (x) can be PH diff (x) = PH(x) - PH(i) or PH diff (x)=PH(i)-PH(x).

[0173] Optionally, in multiple PH diff (x), if x can be equal to i, then multiple PH diff The number of (x) is M; if x cannot be equal to i, then multiple PH diff The number of (x) is M-1. In this case, multiple PH diff (x) may mean the difference between the power headroom of the terminal device corresponding to each signal except the i-th signal in the multiple first signals and the i-th power headroom, and the number of the differences is M-1. diff Whether (x) includes the case where x is equal to i is not specifically limited.

[0174] In the case where the terminal device reports multiple first power information in mode 2, the first TRP is based on the i-th power margin PH(i) reported by the terminal device, and the difference PH between the power margin of the terminal device corresponding to each signal in the multiple first signals and the i-th power margin PH(i) diff (x) The power margin of the terminal device corresponding to each of the multiple first signals can be calculated, and then the transmission power of each of the multiple first signals can be obtained based on the maximum output power of the terminal device configuration reported by the terminal device.

[0175] Optionally, the i-th signal may be a signal among multiple first signals whose transmission timing is closest to or farthest from the transmission timing of the first message, but the present application does not specifically limit which of the multiple first signals the i-th signal is.

[0176] Mode 3: A combination of 1) and c) above. That is, the multiple first power information includes: the maximum output power configured by the terminal device corresponding to any one of the multiple first signals, and the difference between the i-th power margin and the power margins of the terminal devices corresponding to the adjacent signals in the time domain among the multiple first signals.

[0177] Exemplarily, the power margin of the terminal device corresponding to any one signal y among the multiple first signals can be recorded as PH(y), and the power margin of the terminal device corresponding to the signal adjacent to it in the time domain can be recorded as PH(y-1) or PH(y+1). Exemplarily, PH(y-1) can be used to represent the power margin of the terminal device corresponding to the signal whose occupied time domain resources are before signal y and adjacent to signal y, and PH(y+1) can be used to represent the power margin of the terminal device corresponding to the signal whose occupied time domain resources are after signal y and adjacent to signal y.

[0178] Furthermore, the difference between the power headrooms of the terminal devices corresponding to any two signals adjacent in the time domain among the multiple first signals can be recorded as PH diff Optionally, the power headroom of the terminal device corresponding to the signal adjacent to the signal y in the time domain is PH(y-1) for example, PH diff The calculation formula for (y) can be PH diff (y)=PH diff (y)-PH diff (y-1) or PH diff (y)=PH diff (y-1)-PH diff (y). Taking the number of multiple signals as M as an example, the multiple PHs included in this method 3 diff The number of (y) may not exceed M-1.

[0179] In a possible implementation, y can be a continuous identifier of multiple signals in the time domain. The value of y can be, for example, 1, 2, 3...M. In this case, i can also be any integer value from 1 to M, and y or y-1 can take a value equal to i.

[0180] In the case where the terminal device reports multiple first power information in mode 3, the first TRP can be based on the i-th power margin PH(i) reported by the terminal device, and multiple power margin difference values ​​PH diff The power margin difference between the i-th signal and its adjacent signal in the time domain in (y) is used to calculate the power margin of the signal adjacent to the i-th signal, and so on, the power margin of the terminal device corresponding to each signal in the multiple first signals is calculated one by one. Further, based on the maximum output power of the terminal device configuration reported by the terminal device, the transmission power of each signal in the multiple first signals is obtained.

[0181] In the above-mentioned methods 1, 2 and 3, since the maximum output powers configured for the terminal devices corresponding to all or part of the signals sent by the terminal device are the same, when the terminal device reports the power information corresponding to these signals, it can only report the maximum output power configured for one terminal device, which is beneficial to saving bits of the first message and also beneficial to saving communication overhead.

[0182] However, it should be noted that the above-mentioned methods 1, 2 and 3 only take the maximum output power of the terminal device configuration corresponding to any one of the multiple first signals included in the multiple first power information (that is, it may only include the maximum output power of one terminal device configuration) as an example, and does not mean that when the maximum output power of the terminal device configuration corresponding to each of the multiple first signals is the same, multiple power information can only be reported in the manner shown in the above-mentioned methods 1, 2 and 3.

[0183] That is to say, regardless of whether the maximum output power configured for the terminal device corresponding to each signal in the multiple first signals is the same, the reporting method of the above-mentioned multiple first power information can also be the following method 4 to method 12.

[0184] Mode 4: A combination of 2) and a) above. That is, the multiple first power information may include: the power margin of the terminal device corresponding to each of the multiple first signals and the maximum output power configured for the terminal device corresponding to each of the multiple first signals. In this way, the transmission power of each first signal can be obtained based on the power margin of the corresponding terminal device and the maximum output power configured for the terminal device.

[0185] Mode 5: A combination of 2) and b) above. That is, the multiple first power information may include: the maximum output power configured by the terminal device corresponding to each of the multiple first signals, the i-th power margin of the terminal device corresponding to the i-th signal in the multiple first signals, and the difference between the power margin of the terminal device corresponding to each of the multiple first signals and the i-th power margin.

[0186] Exemplarily, the i-th power headroom of the terminal device corresponding to the i-th signal among the multiple first signals can be recorded as PH(i), the power headroom of the terminal device corresponding to any signal among the multiple first signals is recorded as PH(x), and the difference between the power headroom of the terminal device corresponding to any signal among the multiple first signals and PH(i) can be recorded as PH diff (x), PH diff The calculation method of (x) and the meaning of x can be similar to the description in the above method 2, and will not be repeated here.

[0187] In this way, the first TRP can be based on the i-th power margin and multiple PH diff(x), the power margin of the terminal device corresponding to each of the multiple first signals can be calculated, and then further, combined with the maximum output power of the terminal device corresponding to each of the multiple first signals, the transmission power of each of the multiple first signals can be obtained.

[0188] Mode 6: A combination of the above 2) and c). That is, the multiple first power information may include: the maximum output power configured by the terminal device corresponding to each signal in the multiple first signals, the i-th power margin, and the difference between the power margins of the terminal devices corresponding to the adjacent signals in the time domain in the multiple first signals.

[0189] In this case, the difference PH between the power headrooms of the terminal devices corresponding to any two adjacent signals in the time domain among the multiple first signals is diff The calculation method of (y) and y The meaning is similar to the description in method 3 above.

[0190] The first TRP may be based on the i-th power headroom PH(i) reported by the terminal device and a plurality of power headroom difference PH diff The power margin difference between the i-th signal and its adjacent signal in the time domain in (y) is used to calculate the power margin of the signal adjacent to the i-th signal, and so on, the power margin of the terminal device corresponding to each signal in the multiple first signals is calculated one by one. Further, in combination with the maximum output power of the terminal device configuration corresponding to each signal in the multiple first signals, the transmission power of each signal in the multiple first signals can be obtained.

[0191] Mode 7: A combination of the above 3) and a). That is, the multiple first power information may include: the i-th maximum output power configured by the terminal device corresponding to the i-th signal in the multiple first signals, the difference between the maximum output power configured by the terminal device corresponding to each signal in the multiple first signals and the i-th maximum output power, and the power margin of the terminal device corresponding to each signal in the multiple first signals.

[0192] Exemplarily, the i-th maximum output power of the terminal device configuration corresponding to the i-th signal can be recorded as P CMAX,f,c (i) The maximum output power of the terminal device corresponding to any signal among the multiple first signals can be recorded as P CMAX,f,c (x), the maximum output power of the terminal device corresponding to any signal among the multiple first signals and P CMAX,f,c The difference between (i) can be denoted as P CMAX,f,c,diff (x).

[0193] Optionally, P CMAX,f,c,diff The calculation formula for (x) can be P CMAX,f,c,diff (x) = P CMAX,f,c (x)-PCMAX,f,c (i) or P CMAX,f,c,diff (x) = P CMAX,f,c (i)-P CMAX,f,c (x), where x has a meaning similar to that described in the above method 2 and is not repeated here.

[0194] In this way, the first TRP can be based on the i-th maximum output power P CMAX,f,c (i) and multiple P CMAX,f,c,diff (x), the maximum output power of the terminal device corresponding to each of the multiple first signals can be calculated, and then further, combined with the power margin of the terminal device corresponding to each of the multiple first signals, the transmission power of each of the multiple first signals can be obtained.

[0195] Mode 8: A combination of the above 3) and b). That is, the multiple first power information may include: the i-th maximum output power of the terminal device configuration corresponding to the i-th signal in the multiple first signals, the difference between the maximum output power of the terminal device configuration corresponding to each signal in the multiple first signals and the i-th maximum output power, the i-th power margin of the terminal device corresponding to the i-th signal in the multiple first signals, and the difference between the power margin of the terminal device corresponding to each signal in the multiple first signals and the i-th power margin.

[0196] In this manner, the calculation method of the maximum output power of the terminal device corresponding to each of the multiple first signals can refer to the description in manner 7, and the calculation method of the power margin of the terminal device corresponding to each of the multiple first signals can refer to the description in manner 2, which will not be repeated here. Further, the transmission power of each first signal can be obtained based on the power margin of the terminal device corresponding to it and the maximum output power configured by the terminal device.

[0197] Mode 9: A combination of the above 3) and c). That is, the multiple first power information may include: the i-th maximum output power of the terminal device configuration corresponding to the i-th signal in the multiple first signals, the difference between the maximum output power of the terminal device configuration corresponding to each signal in the multiple first signals and the i-th maximum output power, the i-th power margin, and the difference between the power margins of the terminal devices corresponding to adjacent signals in the time domain in the multiple first signals.

[0198] In this manner, the calculation method of the maximum output power of the terminal device corresponding to each of the multiple first signals can refer to the description in manner 7, and the calculation method of the power margin of the terminal device corresponding to each of the multiple first signals can refer to the description in manner 3, which will not be repeated here. Further, the transmission power of each first signal can be obtained based on the power margin of the corresponding terminal device and the maximum output power configured by the terminal device.

[0199] Mode 10: A combination of 4) and a) above. That is, the multiple first power information may include: the i-th maximum output power, the difference between the maximum output powers of the terminal devices corresponding to the adjacent signals in the time domain in the multiple first signals, and the power margin of the terminal device corresponding to each signal in the multiple first signals.

[0200] The i-th maximum output power P can be recorded as P CMAX,f,c (i) The maximum output power of the terminal device corresponding to any one signal y among the multiple first signals can be recorded as P CMAX,f,c (y), the maximum output power of the terminal device corresponding to the adjacent signal in the time domain can be recorded as P CMAX,f,c (y-1) or P CMAX,f,c (y+1), the difference in the maximum output power of the terminal devices corresponding to any two adjacent signals in the time domain among the multiple first signals can be recorded as P CMAX,f,c,diff (y).

[0201] Optionally, the maximum output power of the terminal device corresponding to the signal adjacent to the signal y in the time domain is P CMAX,f,c (y-1) for example, P CMAX,f,c,diff The calculation formula for (y) can be P CMAX,f,c,diff (y) = P CMAX,f,c (y)-P CMAX,f,c (y-1), or P CMAX,f,c,diff (y)=P CMAX,f,c (y-1)-P CMAX,f,c (y), where y The meaning is similar to that described in method 3 above and will not be repeated here.

[0202] The first TRP can be based on the i-th maximum output power P reported by the terminal device. CMAX,f,c (i), and the difference of multiple maximum output powers P CMAX,f,c,diff The maximum output power of the terminal device corresponding to the signal adjacent to the ith signal is calculated based on the power margin difference between the ith signal and its time domain adjacent signal in (y), and so on, the maximum output power of the terminal device corresponding to each of the multiple first signals is calculated one by one, and then the transmission power of each of the multiple first signals is obtained based on the power margin of the terminal device corresponding to each of the multiple first signals.

[0203] Mode 11: A combination of the above 4) and b). That is, the multiple first power information may include: the i-th maximum output power, the difference between the maximum output powers of the terminal devices corresponding to the adjacent signals in the time domain in the multiple first signals, the i-th power margin, and the difference between the power margin of the terminal device corresponding to each signal in the multiple first signals and the i-th power margin.

[0204] In this way, the calculation method of the maximum output power of the terminal device corresponding to each signal in the multiple first signals can refer to the description in method 10, and the calculation method of the power margin of the terminal device corresponding to each signal in the multiple first signals can refer to the description in method 2, which will not be repeated here.

[0205] Furthermore, the transmission power of each first signal may be obtained based on the power margin of its corresponding terminal device and the maximum output power configured for the terminal device.

[0206] Mode 12: A combination of the above 4) and c). That is, the multiple first power information may include: the i-th maximum output power, the difference between the maximum output powers of the terminal devices corresponding to the adjacent signals in the time domain in the multiple first signals, the i-th power margin, and the difference between the power margins of the terminal devices corresponding to the adjacent signals in the time domain in the multiple first signals.

[0207] In this manner, the calculation method of the maximum output power of the terminal device corresponding to each of the multiple first signals can refer to the description in manner 10, and the calculation method of the power margin of the terminal device corresponding to each of the multiple first signals can refer to the description in manner 3, which are not described here. Further, the transmission power of each first signal can be obtained based on the power margin of the terminal device corresponding to it and the maximum output power configured by the terminal device.

[0208] In an embodiment of the present application, when the maximum output power configured for the terminal device corresponding to each of the multiple first signals is not exactly the same, based on the reporting methods of methods 4 to 12 above, the first TRP can obtain the specific value of the maximum output power configured for the terminal device corresponding to each of the multiple first signals, which is beneficial to improving the accuracy of the transmission power of each signal obtained by the first TRP.

[0209] In another possible implementation, multiple first power information may be reported through the transmit power corresponding to multiple first signals. The contents included in the transmit power corresponding to the multiple first signals, that is, the reporting method of the multiple first power information may also include the following:

[0210] Mode 13: Transmitting power of each of the multiple first signals. In this way, the device receiving the first message can directly obtain the transmitting power of each of the multiple first signals without performing complex calculations, which is conducive to saving device computing power.

[0211] Mode 14: the i-th transmission power of the i-th signal among multiple first signals, and the difference between the transmission power of each signal among the multiple first signals and the i-th transmission power.

[0212] Exemplarily, the i-th transmission power of the i-th signal among the multiple first signals can be recorded as P(i), the transmission power of any one of the multiple first signals can be recorded as P(x), and the difference between the transmission power of any one of the multiple first signals and the i-th transmission power can be recorded as P diff (x), P diff The calculation formula for (x) can be P diff (x) = P(x) - P(i) or P diff (x)=P(i)-P(x), where x has a meaning similar to that in method 2 above.

[0213] In this way, the first TRP can be based on P(i) and multiple P diff (x) Calculate the transmission power of each signal.

[0214] Mode 15: the i-th transmission power, and the difference between the transmission powers corresponding to adjacent signals in the time domain in a plurality of first signals.

[0215] Exemplarily, the i-th transmission power can be recorded as P(i), the transmission power of any one signal y in the multiple first signals can be recorded as P(y), the transmission power of the signal adjacent to it in the time domain can be recorded as P(y-1) or P(y+1), and the difference between the transmission powers of any two adjacent signals in the time domain in the multiple first signals can be recorded as P diff (y).

[0216] Optionally, the transmission power of a signal adjacent to signal y in the time domain is taken as P(y-1) for example, P diff The calculation formula for (y) can be P diff (y) = P(y) - P(y-1) or P diff (y)=P(y-1)-P(y), where y The meaning is similar to that in method 3 above.

[0217] In this way, the first TRP can be based on P(i) and multiple P diff (y) The transmission power of each of the multiple first signals is obtained by calculation.

[0218] Methods 14 and 15 are more conducive to saving bits of the first message and transmission power consumption than directly reporting the transmission power of each signal, because the data magnitude of the difference is smaller.

[0219] It should be understood that there is a first correspondence between the multiple first power information and the resources of each of the multiple first signals. As an optional embodiment, the first correspondence can be indicated in one or more of the following ways: protocol agreement, network device indication, included in the first message, or included in other messages sent by the terminal device.

[0220] Combine the following Figure 5 The indication method of the first corresponding relationship is described in detail.

[0221] Figure 5 The example in FIG. 1 shows the transmission timing of the terminal device sending multiple first signals and the transmission timing of the first message. Figure 5 As shown, multiple first signals may be part of the signals sent by the terminal device. The "signal sent by the terminal device" described here may refer to a signal included in a signal sending period that is closest to the transmission timing of the first message before the terminal device sends the first message. The period for sending the first message may be the same as the period for sending the first signal by the terminal device, but this application does not limit this.

[0222] There are several possible implementations of indicating the first corresponding relationship.

[0223] In a first possible implementation, the coding order of the multiple first power information corresponding to the multiple first signals may be the same as or opposite to the transmission order of the multiple first signals, which may also be understood as the first corresponding relationship being implicitly indicated by the coding order of the multiple power information.

[0224] Example 1: Taking the reporting of multiple first power information through the above-mentioned method 1 as an example, in the multiple first power information, the encoding order of the power headrooms of multiple terminal devices corresponding to the multiple first signals can be the same as or opposite to the transmission order of the multiple first signals. Figure 5 Taking the transmission order of the signals (or signal transmission timings) 0, 1, 2, 3…M-1 shown in the figure as an example, the coding order of the power margins of the terminal devices corresponding to these signals can be the same as their transmission order (or can also be understood as the positive order of the transmission order of these signals), for example, it can be PH(0), PH(1), PH(2), PH(3)…PH(M-1), and the coding order of the power margins of the terminal devices corresponding to these signals can also be opposite to their transmission order (or can also be understood as the reverse order of the transmission order of these signals), for example, it can be PH(M), PH(M-2), PH(M-3)…PH(0), where PH(0) is used to represent the power margin corresponding to signal 0, and the rest are similar and will not be repeated.

[0225] It should be understood that when multiple first power information includes the maximum output power of multiple terminal devices corresponding to multiple first signals (for example, the above-mentioned methods 4 to 6) and multiple first power information includes multiple transmission powers corresponding to multiple first signals (for example, the above-mentioned method 13), the encoding order of the maximum output power and multiple transmission powers of the multiple terminal devices can be similar to the encoding order of the power margin of the above-mentioned multiple terminal devices, and will not be repeated.

[0226] Example 2: Taking the reporting of multiple first power information through the above-mentioned method 2 as an example, the specific order of the i-th signal can also be agreed upon. The i-th signal can be the signal closest to the first message transmission timing among the multiple first signals, for example Figure 5 The signal M-1 shown in FIG. 1 is not specifically limited in this application. diff The coding order of (x) can be PH diff (0), PH diff (1) PH diff (2)…PH diff (M-1), or PH diff (M-1), PH diff (M-2), PH diff (M-3)…PH diff (0), where PH diff (0) is used to represent the difference between the power headroom of the terminal device corresponding to signal 0 and the power headroom of the terminal device corresponding to signal M-1, PH diff (1) is used to represent the difference between the power headroom of the terminal device corresponding to signal 1 and the power headroom of the terminal device corresponding to signal M-1. The remaining PH diff (2)…PH diff The meaning of (M-1) is similar and will not be elaborated on here.

[0227] It should be understood that the multiple P described in the above methods 7 to 9 CMAX,f,c,diff (x) Multiple Ps described in Method 14 diff The encoding method of (x) can also be the same as the multiple PHs shown in Example 2. diff The coding sequence of (x) is similar and will not be repeated here.

[0228] It should also be understood that the multiple PHs described in the above methods 3, 6, and 9 diff (y) Multiple Ps described in Methods 10 to 12 CMAX,f,c,diff The coding order of (y) can also refer to Example 2 and will not be repeated here.

[0229] In a second possible implementation, the first correspondence may be indicated by a network device, which may be, for example, a first TRP or a second TRP. Exemplarily, before the first TRP receives the first message, the first TRP sends an indication message to the terminal device, and the indication message may include the coding order of multiple first power information, or the indication message may include the time domain position of a reference signal (which may be understood as the i-th signal) in multiple first signals and the coding order of multiple first power information.

[0230] In a third possible implementation manner, the first corresponding relationship is included in the first message.

[0231] As an optional embodiment, the first message includes resource indexes of multiple first signals corresponding one-to-one to multiple first power information.

[0232] In a fourth possible implementation, the terminal device may also indicate the first correspondence through other messages other than the first message. This indication message may include the coding order of multiple first power information, or the indication information may include the time domain position of the reference signal (which can be understood as the i-th signal) in multiple first signals and the coding order of multiple first power information. The present application does not limit the sending timing of the indication message sent by the terminal device to indicate the first correspondence.

[0233] As an optional embodiment, in the above method 400, the multiple power information includes power information corresponding to multiple signals sent by the terminal device to the first TRP, and / or multiple power information corresponding to multiple signals sent by the terminal device to the second TRP, and the first TRP and the second TRP are two different transmission receiving points in the same cell.

[0234] It should be understood that the power information reporting method of the signals belonging to the same signal set in the signals sent by the terminal device to the first TRP, and the power information reporting method of the signals belonging to the same signal set in the signals sent by the terminal device to the second TRP, can be similar to the reporting methods of the above-mentioned multiple first power information, that is, both can be any one of the above-mentioned methods 1 to 15.

[0235] In the case where multiple power information includes power information corresponding to multiple signals sent by the terminal device to the first TRP, and multiple power information corresponding to multiple signals sent by the terminal device to the second TRP, the first message may include at least two sets of power information for the first TRP and the second TRP for each cell in at least one cell. In order to distinguish the two sets of power information, in a possible implementation, the first message also includes a first identifier and / or a second identifier, the first identifier is used to indicate the power information related to the first TRP, and the second identifier is used to indicate the power information related to the second TRP.

[0236] In this way, after receiving the first message, the first TRP can respectively identify the power information related to the first TRP and the power information related to the second TRP based on the first identifier and / or the second identifier, and forward the power information related to the second TRP to the second TRP so that the second TRP can perform calculations related to the power information, or the first TRP can perform calculations related to the power information based on the first message.

[0237] Optionally, the terminal device may send multiple SRSs to both the first TRP and the second TRP, the first identifier may be a common parameter set of the SRS related to the first TRP, and the second identifier may be a common parameter set related to the second TRP. When the network side instructs the terminal device to send SRSs to the first TRP and the second TRP respectively, the network side may configure the terminal device with a common parameter set of the SRS related to the first TRP and a common parameter set related to the second TRP. Further, the first TRP may identify which TRP the power information included in the first message is related to through the first identifier and / or the second identifier.

[0238] As an optional embodiment, the number of signals related to the first TRP, and / or the number of signals related to the second TRP can be determined by protocol agreement, network device indication or other terminal device indication. In the case where the number M1 of signals related to the first TRP is the same as the number M2 of signals related to the second TRP, the multiple power information includes: the transmission power difference information of the signals corresponding to the M1 signals sent by the terminal device to the first TRP and the M2 signals sent by the terminal device to the second TRP.

[0239] Optionally, the signal sending period of the M1 signals sent by the terminal device to the first TRP and the M2 signals sent by the terminal device to the second TRP may be the same.

[0240] Figure 6 The example shows the transmission timing of M1 signals sent by the terminal device to the first TRP, the transmission timing of M2 signals sent by the terminal device to the second TRP, and the transmission timing of the first message. Optionally, the signal corresponding to the M2 signals sent by the terminal device to the second TRP in the M1 signals sent by the terminal device to the first TRP may include, for example Figure 6 Shown in the figure are signal 0 among the M1 signals and signal 0 among the M2 signals, signal 1 among the M1 signals and signal 1 among the M2 signals, signal 2 among the M1 signals and signal 2 among the M2 signals… signal M1-1 among the M1 signals and signal M2-1 among the M2 signals, a total of M1 pairs.

[0241] As an optional embodiment, the transmit power difference of the M1 pair of signals may be reported in the following three possible ways:

[0242] Method 1: M1 transmit power differences; wherein the j-th transmit power difference △P(j) among the M1 transmit power differences is: the difference between the transmit power P1(j) of the j-th signal among the M1 signals and the transmit power P2(j) of the j-th signal among the M2 signals, j=1, 2…M1.

[0243] In the case where the terminal device reports multiple power information in mode 1, the first TRP can obtain the difference between path loss a and path loss b based on the jth transmit power difference △P (j) and the difference between the received power of the jth signal in the M1 signal and the received power of the jth signal in the M2 signal. Path loss a is the path loss between the terminal device corresponding to the jth signal in the M1 signal and the first TRP, and path loss b is the path loss between the terminal device corresponding to the jth signal in the M2 signal and the second TRP. In this way, there is no need to obtain the difference between the transmit power and the receive power of the jth signal corresponding to the first TRP and the difference between the transmit power and the receive power of the jth signal of the second TRP and then perform a subtraction, which is conducive to simplifying the process of the first TRP obtaining the difference between path loss a and path loss b, and is conducive to saving equipment computing power.

[0244] Mode 2: △P(j), the difference between each of the M1 transmit power differences and △P(j).

[0245] It should be understood that method 2 is intended to report a benchmark transmit power difference △P(j), as well as the difference between each of the M1 transmit power differences and △P(j), where △P(j) is any one of the M1 transmit power differences. The present application does not make any specific limitation on which of the M1 transmit power differences is to be selected as the benchmark transmit power difference.

[0246] When the terminal device reports multiple power information in mode 2, the first TRP can also obtain M1 transmit power differences based on the difference between △P(j), each of the M1 transmit power differences and △P(j), and then further obtain the difference between the path loss a and the path loss b. Mode 2 reports a reference value and multiple differences in this way, which is conducive to saving the bits occupied by the first message and reducing signaling overhead.

[0247] Mode 3: △P(j), the difference between the transmit power differences of two pairs of signals adjacent in the time domain among the M1 transmit power differences.

[0248] Exemplarily, two pairs of signals adjacent in the time domain can be represented as follows: Figure 6 The difference between the transmit power differences of signal 0 of the M1 signals and signal 0 of the M2 signals, and signal 1 of the M1 signals and signal 1 of the M2 signals shown in FIG. 1 can be expressed as ∆P diff (1) is used to represent the difference between the transmit power difference ∆P(1) between signal 1 in the M1 signals and signal 1 in the M2 signals, and the transmit power difference ∆P(0) between signal 0 in the M1 signals and signal 0 in the M2 signals. In some implementations, the difference between the transmit power differences of two pairs of adjacent signals in the time domain can be denoted as ∆P diff (j), which can be calculated by, for example, ∆P diff (j)=∆P(j)-∆P(j-1), j=1, 2…M1, but this is not limited in this application.

[0249] It is worth noting that the embodiment of the present application does not limit whether the signal sent by the terminal device to the first TRP and the signal sent by the terminal device to the second TRP are of the same signal type, nor does it limit whether they belong to the same signal set.

[0250] When the terminal device reports multiple power information in mode 3, the first TRP can be based on △P (j) and the difference between the transmit power differences of two pairs of signals adjacent in the time domain in the M1 transmit power differences, and then further obtain the difference between the path loss a and the path loss b. Mode 3 is conducive to saving the bits occupied by the first message and reducing the signaling overhead.

[0251] It should be understood that there is a second correspondence between the resources of each signal in the M1 signals and / or the resources of each signal in the M2 signals and the transmission power difference information. As an optional embodiment, the second correspondence can be indicated in one or more of the following ways: protocol agreement, network device indication, included in the first message, or included in other messages sent by the terminal device.

[0252] Specifically, the indication of the second correspondence is similar to the indication of the first correspondence, and will not be repeated here.

[0253] In a possible implementation, when the second correspondence is included in the first message, the first message also includes: a resource index of a signal related to the first TRP corresponding to any power difference information, and / or a resource index of a signal related to the second TRP corresponding to any power difference information. Figure 6The transmission power difference ΔP(1) between signal 1 among the M1 signals and signal 1 among the M2 signals shown in may be associated with a resource index of signal 1 among the M1 signals and / or a resource index of signal 1 among the M2 signals.

[0254] As an optional embodiment, the message type of the first message is any one of the following: a medium access control MAC message, a physical uplink data channel PUSCH message, a physical uplink control channel PUCCH message, or a radio resource control RRC message.

[0255] Specifically, the first message may be uplink control information (uplink control information, UCI) in the PUCCH, or may be an uplink MAC CE message.

[0256] Figure 7 A flow chart of a communication method 700 provided in an embodiment of the present application is shown. The method 700 may be applicable to a communication system 700.

[0257] The method 700 may include the following steps:

[0258] S701~S703 are similar to the above-mentioned S401~S403 and will not be described in detail.

[0259] S704. The terminal device determines a second message, where the second message includes multiple power information corresponding to multiple signals of each cell in at least one cell.

[0260] S705. The terminal device sends a second message to the second TRP; correspondingly, the second TRP receives the second message.

[0261] S706. The second TRP is calculated using multiple power information.

[0262] Optionally, the first message sent by the terminal device to the first TRP and the second message sent to the second TRP may be the same or different, and this application does not limit this.

[0263] When the first message sent by the terminal device to the first TRP is different from the second message sent to the second TRP, the multiple signals in the first message may be all or part of the signals sent by the terminal device to the first TRP, and the multiple power information may be the power information of all or part of the signals sent by the terminal device to the first TRP, the multiple signals in the second message may be all or part of the signals sent by the terminal device to the second TRP, and the multiple power information may be the power information of all or part of the signals sent by the terminal device to the second TRP.

[0264] It should be understood that regardless of whether the second message is the same as the first message, the meaning and reporting method of the multiple power information included in the second message can be similar to the meaning and reporting method of the multiple power information included in the first message described above, and will not be repeated.

[0265] According to the method provided in the embodiment of the present application, the terminal device can report multiple power information corresponding to multiple signals in each cell of at least one cell to the first TRP / second TRP at one time. Compared with the related technology in which the terminal device can only report the power information of one signal in one cell at a time, in the scenario where calculation is required based on multiple power information of multiple signals, the terminal device does not need to report the multiple power information of multiple signals by reporting multiple times, which is beneficial to saving the signaling overhead of the terminal device, the first TRP and the second TRP.

[0266] It should be understood that the size of the sequence numbers in the above embodiments does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic.
