[0057] The communication system to which the embodiments of the present application are applicable includes but is not limited to a Long Term Evolution (LTE) system, a 5th-generation (5G) system, an NR system, and a future evolution system or a plurality of communication fusion systems.

[0058] The present application mainly relates to the communication between a terminal device and a network device. Among them:
[0059] The network device in the embodiments of the present application can also be referred to as an access network device, for example, a base station (Base Station, BS) (also referred to as a base station device), and the network device is a device deployed in a radio access network (Radio Access Network, RAN) to provide wireless communication functions. For example, the device providing the base station function in the second generation (2nd-Generation, 2G) network includes a base wireless transceiver station (Base Transceiver Station, BTS), the device providing the base station function in the third generation (3rd-Generation, 3G) network includes a node B (NodeB), the device providing the base station function in the fourth generation (4th-Generation, 4G) network includes an evolved node B (evolved NodeB, eNB), in the wireless local area network (Wireless Local Area Networks, WLAN), the device providing the base station function is an access point (Access Point, AP), the device providing the base station function in the NR includes a next generation base station node (next generation Node Base station, gNB), and a continuously evolving node B (ng-eNB), wherein the gNB and the terminal device communicate with each other using the NR technology, the ng-eNB and the terminal device communicate with each other using the evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and the gNB and the ng-eNB can be connected to the 5G core network. The network device in the embodiments of the present application also includes devices providing base station functions in future new communication systems and the like.
[0060] The terminal equipment in the embodiments of the present application can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (Mobile Station, MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment can also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal equipment in a future 5G network or a terminal equipment in a future evolved Public Land Mobile Network (PLMN), etc. The embodiments of the present application are not limited thereto. The terminal equipment can also be referred to as user equipment (User Equipment, UE), terminal, etc.
[0061] Please refer to Figure 1 When the terminal equipment 101 transmits the sensing signal to the sensing target 103, the propagation path of the sensing signal is from the terminal equipment 101 to the sensing target 103, and then the sensing target 103 reflects the sensing signal to the terminal equipment 101, and the terminal equipment 101 receives the sensing signal. That is, when the terminal equipment 101 performs single station sensing, the sensing signal is bidirectionally propagated, and the terminal equipment 101 is both the sender and the receiver of the sensing signal. In this way, when the terminal equipment 101 controls the transmission power of the sensing signal, it needs to calculate the path loss of the bidirectional propagation between the terminal equipment 101 and the sensing target 103, and the reflection loss of the sensing target 103.
[0062] In addition, the terminal equipment 101 can also transmit a communication signal to other devices 102 or to a network device for communication. The communication signal can be data or signaling, etc.
[0063] As described in the background, when multiple signals such as sensing signals and / or communication signals need to be transmitted at the same time, how to implement power control is a problem that needs to be solved at present.
[0064] The application provides a method. A network device can send power configuration information for a terminal device. The power configuration information can be used to determine the limited power of N signals when the transmission time overlaps. Then, the terminal device can determine the first transmission power of each signal in the N signals when the transmission time overlaps under the limitation of the power indicated by the power configuration indication information. The terminal device can send each signal by using the transmission power that does not exceed the first transmission power of each signal. The technical scheme of the application determines the transmission power of each signal by using the power configuration information. In the case that the total transmission power of the terminal device is limited, the rationality of the transmission power configuration of each signal is ensured, and the power sharing when multiple signals are simultaneously sent is realized.
[0065] Referring to Figure 2 The communication method provided by the application comprises the following steps:
[0066] Step 201: A network device sends power configuration information. Correspondingly, a terminal device receives the power configuration information.
[0067] Step 202: The terminal device determines the first transmission power of each signal in N signals according to the power configuration information.
[0068] Step 203: The terminal device simultaneously sends the N signals according to the first transmission power of the N signals.
[0069] It should be noted that the serial numbers of the steps in the embodiment do not represent the limitation on the execution sequence of the steps.
[0070] It can be understood that, in a specific implementation, the communication method can be realized in the form of a software program that runs in a processor integrated in a chip or a chip module. The method can also be realized in the form of software combined with hardware, and the application does not make any limitation.
[0071] In the embodiment, the N signals can be selected from communication signals and sensing signals. That is, the N signals can be N communication signals, N sensing signals, or part of the N signals are communication signals and the remaining part are sensing signals.
[0072] In one specific embodiment, the number of the N signals can be two, one of which is a sensing signal and the other is a communication signal. The sensing signal and the communication signal can be simultaneously sent in the form of frequency division multiplexing on the same or different carriers in a specific frequency band.
[0073] It should be noted that the number or type of the N signals can be configured according to actual application requirements, and the application does not make any limitation.
[0074] In this embodiment, the network device can configure power configuration information for the terminal device, which can indicate the limit power of the N signals when the transmission time overlaps, for example, the limit power of each signal or the total limit power. This is because the total transmit power of the terminal device is limited, and when there are multiple signals to be transmitted, the transmit power of each signal needs to be limited; and different signals have different priorities, so it is necessary to reasonably allocate the transmit power to each signal to ensure the normal transmission of each signal.
[0075] In a specific implementation, the power configuration information configured by the network device can indicate the limit power of each signal when the N signals overlap in transmission time. Accordingly, the terminal device determines the first transmit power of each signal according to the limit power of each signal. The power configuration information can also indicate the total limit power of the N signals when the transmission time overlaps, and accordingly, the terminal device determines the first transmit power of each signal according to the total limit power.
[0076] In this embodiment, the first transmit power of the signal represents the maximum transmit power of the signal when the N signals are transmitted simultaneously.
[0077] The following will be described in detail with the example that the N signals include a first signal and a second signal, and the power configuration information contains different contents.
[0078] 1. The power configuration information includes the first configuration power P' of the first signal and the first configuration power P' of the second signal when the transmission time overlaps. max1 max2 .
[0079] Unlike the first transmit power representing the maximum transmit power of the signal when actually transmitted, the first configuration power of the signal in this embodiment is the maximum transmit power of the signal configured by the network device when the N signals are transmitted simultaneously.
[0080] Accordingly, please refer to Figure 3 In a specific implementation of step 302, when the transmission time of the first signal and the second signal overlaps, the terminal device determines the first transmit power P1 of the first signal as the first configuration power P' of the first signal, and determines the first transmit power P2 of the second signal as the first configuration power P' of the second signal. max1 max2 .
[0081] In the implementation of step 303, the terminal device transmits the first signal by using a transmission power not exceeding the first transmission power P1 of the first signal, and transmits the second signal by using a transmission power not exceeding the first transmission power P2 of the second signal. In other words, the actual transmission power of the terminal device for transmitting the first signal is less than or equal to the first transmission power P1 of the first signal, and the actual transmission power of the terminal device for transmitting the second signal is less than or equal to the first transmission power P2 of the second signal.
[0082] 2. The power configuration information includes the second configuration power P2 of the first signal when the transmission time of the first signal does not overlap with the transmission time of the second signal max1 , the second configuration power P2 of the second signal max2 , and the maximum combined transmission power P of all the signals in the first signal and the second signal max,all .
[0083] In this embodiment, the maximum combined transmission power is the sum of the transmission power of the first signal and the second signal on one carrier, or the sum of the transmission power of the first signal and the second signal on multiple carriers.
[0084] Correspondingly, please refer to Figure 4 , in the implementation of step 402, when the transmission time of the first signal does not overlap with the transmission time of the second signal, the terminal device determines the first transmission power P1 of the first signal as the second configuration power P2 of the first signal max1 , and determines the first transmission power P2 of the second signal as the second configuration power P2 of the second signal max2 .
[0085] In the implementation of step 403, when the transmission time of the first signal overlaps with the transmission time of the second signal, the first transmission power of the first signal and the first transmission power of the second signal are determined according to the priority order of the first signal and the second signal and the maximum combined transmission power P max,all . Specifically, if the priority of the first signal is higher than the priority of the second signal, the first transmission power P1 of the first signal is determined as the second configuration power P2 of the first signal max1 , and the first transmission power P2 of the second signal is determined as the difference between the maximum combined transmission power P max,all and the first transmission power P1 of the first signal, that is, P2=P max,all -P1.
[0086] On the contrary, if the priority of the second signal is higher than the priority of the first signal, the first transmission power P2 of the second signal is determined as the second configuration power P2 of the second signal max2 , and the first transmission power P1 of the first signal is determined as the difference between the maximum combined transmission power P max,all and the first transmission power P2 of the second signal, that is, P1=P max,allP2.
[0087] It can be understood that in actual implementation, the terminal device selectively performs one of step 402 and step 403 or both steps.
[0088] In the implementation of step 404, the terminal device transmits the first signal by using a transmission power that does not exceed the first transmission power P1 of the first signal, and transmits the second signal by using a transmission power that does not exceed the first transmission power P2 of the second signal.
[0089] The above embodiments are described by taking the terminal device transmitting the first signal and the second signal simultaneously as an example. In actual implementation, the terminal device can need to transmit a larger number of signals simultaneously. In this case, the terminal device can allocate the maximum combined transmission power in the following manner.
[0090] The terminal device allocates the first transmission power to each signal in descending order of the priority of the N signals until the maximum combined transmission power P max,all is allocated, where for the K signals to which the first transmission power is allocated, the first transmission power of each of the K signals is the second configured power of the signal, or the first transmission power of the K-1 signals with the highest priority among the K signals is the second configured power of the signal, and the first transmission power of the Kth signal is the maximum combined transmission power P max,all , K is less than or equal to N.
[0091] 3. The power configuration information includes the maximum combined transmission power P max,all of all the signals in the first signal and the second signal, and the bandwidth B1 of the first signal and the bandwidth B2 of the second signal.
[0092] Correspondingly, when the transmission time of the first signal and the second signal overlaps, the terminal device calculates the sum of the bandwidth B1 of the first signal and the bandwidth B2 of the second signal as the total bandwidth, and calculates the ratio of the bandwidth B1 of the first signal to the total bandwidth, and the product of the maximum combined transmission power P max,all and the ratio is the first transmission power P1 of the first signal, that is, the first transmission power P2 of the second signal.
[0093] The terminal device transmits the first signal by using a transmission power that does not exceed the first transmission power P1 of the first signal, and transmits the second signal by using a transmission power that does not exceed the first transmission power P2 of the second signal.
[0094] The above embodiment is described by taking the terminal device simultaneously sending the first signal and the second signal as an example. In actual implementation, the terminal device can need to simultaneously send a larger number of signals. In this case, the terminal device can allocate the maximum combined transmission power in the following manner.
[0095] For each type of signal, a ratio of the bandwidth of the signal to the sum of the bandwidths of all signals is calculated; and the maximum combined transmission power is proportionally allocated according to the ratios corresponding to the respective signals to obtain the first transmission power of each type of signal.
[0096] In another non-limiting embodiment, when the terminal device simultaneously sends the first signal and the second signal, the terminal device can also allocate the maximum combined transmission power P max,all .
[0097] Specifically, the first transmission power of the first signal is calculated by using the following formula wherein α is a preset adjustment coefficient, and the preset adjustment coefficient is configured to be a product of the bandwidth ratio and less than or equal to 1, that is, to make always less than or equal to 1. Correspondingly, the first transmission power of the second signal is calculated by using the following formula
[0098] It should be noted that the preset adjustment coefficient α can be a value specified by a communication standard protocol or pre-configured by the base station, and the present application does not limit this.
[0099] 4. The power configuration information includes the first configuration power P' max1 of the first signal and the first configuration power P' max2 of the second signal when the transmission time overlaps, and the second configuration power P max1 of the first signal and the second configuration power P max2 of the second signal when the transmission time does not overlap.
[0100] In the embodiment, when the transmission time of the first signal and the second signal overlaps, the terminal device determines the first transmission power P1 of the first signal as the first configuration power P' max1 of the first signal, and determines the first transmission power P2 of the second signal as the first configuration power P' max2 .
[0101] When the transmission time of the first signal and the second signal does not overlap, the terminal device determines the first transmission power P1 of the first signal as the second configuration power P max1 of the first signal, and determines the first transmission power P2 of the second signal as the second configuration power P max2 .
[0102] In one specific application scenario, the N signals can be periodic signals, and the N signals respectively have a transmission period. Then, it is possible that the transmission time of the N signals does not overlap at a certain moment, and the transmission time of the N signals overlaps at the next moment. For example, taking the first signal and the second signal as an example, the transmission period of the first signal is 4 milliseconds (ms), and the transmission period of the second signal is 8 ms. Then, at the 4th ms, the transmission time of the first signal and the second signal does not overlap, and at the 8th ms, the transmission time of the first signal and the second signal overlaps.
[0103] In this case, the terminal device needs to respectively calculate the first transmission power of the N signals when the transmission time overlaps and the first transmission power of the N signals when the transmission time does not overlap. This requires that the power configuration information can indicate the limit power of the N signals when the transmission time overlaps and when the transmission time does not overlap.
[0104] In one specific embodiment, the power configuration information includes the second configuration power P max1 of the first signal and the second configuration power P max2 of the second signal when the transmission time does not overlap, and the maximum combined transmission power P max,all of all signals in the first signal and the second signal. For details, please refer to the description of mode 2.
[0105] In another specific embodiment, the power configuration information includes the second configuration power P max1 of the first signal and the second configuration power P max2 of the second signal when the transmission time does not overlap, and the maximum combined transmission power P max,all of all signals in the first signal and the second signal, and the bandwidth B1 of the first signal and the bandwidth B2 of the second signal.
[0106] In yet another specific embodiment, the power configuration information includes the second configuration power P max1 of the first signal and the second configuration power P max2 of the second signal when the transmission time does not overlap, and the first configuration power P’ max1 of the first signal and the first configuration power P’ max2 of the second signal when the transmission time overlaps.
[0107] In another specific application scenario, please refer to Figure 5 Before determining the first transmission power of each signal, the terminal device can also receive scheduling information of each signal in step 501, and the scheduling information of each signal is used to indicate the transmission resource of each signal. Correspondingly, the network device configures and transmits the scheduling information of each signal.
[0108] In this embodiment, the terminal device determines the transmission resource of each signal according to the scheduling information of each signal, and transmits each signal on the transmission resource of each signal by using the transmission power not exceeding the first transmission power of each signal.
[0109] For more specific implementation of the embodiments of the application, please refer to the foregoing embodiments, which will not be repeated here.
[0110] For more specific implementation of the embodiments of the application, please refer to the foregoing embodiments, which will not be repeated here. Figure 6 Figure 6 A communication apparatus 60 is shown. When the communication apparatus 60 is used in a terminal device, the communication apparatus 60 can include:
