Description

Signal sending method and device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 28, 2023, with application number 202311855785.6 and application name “Signal Transmitting Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more specifically, to a signal sending method and device. Background Art

[0003] With the continuous development of communication systems, terminal devices support simultaneous access to two network devices. This access method is called dual connectivity (DC), in which one network device is the main network device and the other network device is the auxiliary network device. The one or more cells provided by the main network device to the terminal device are called the master cell group (MCG), and the one or more cells provided by the auxiliary network device to the terminal device are called the secondary cell group (SCG). In order to increase the rate at which the terminal device sends uplink signals to the network device, the terminal device operating in DC mode can simultaneously send uplink signals to the network device on the carriers in MCG and SCG in the same time period, but the total power of the uplink signals sent by the terminal device on all carriers cannot exceed the preset threshold of the terminal device's transmit power. Therefore, if the total power of the uplink signals sent by the terminal on the carriers in MCG and SCG exceeds the maximum transmit power, the terminal device needs to actively reduce the transmit power on one or more carriers.

[0004] Currently, some terminal devices can determine the priority of uplink communication signals sent on carriers in the MCG and SCG during the same time period based on the signal type and reduce the transmission power of the low-priority signal. If the terminal device sends the same signal type on the two CGs, the transmission power of the signal on the SCG can be reduced based on the fact that the priority of the signal on the MCG is higher than that of the signal on the SCG.

[0005] However, the signal transmission method of the above-mentioned terminal device cannot effectively control the transmission power of the uplink signal in the uplink multi-carrier communication perception integrated scenario. Summary of the Invention

[0006] The present application provides a signal transmission method and apparatus. In an uplink multi-carrier communication perception integrated scenario, when a terminal device simultaneously transmits any two different uplink signals, including an uplink perception signal, an uplink synaesthesia signal, or an uplink communication signal, on two different carriers, the transmission power of the two uplink signals can be effectively controlled, thereby facilitating an increase in the rate at which the terminal device transmits uplink signals to a network device.

[0007] In a first aspect, a signal transmission method is provided, comprising: determining a first transmit power of a first signal in a first time unit on a first carrier, and determining a second transmit power of a second signal in a second time unit on a second carrier, wherein the first time unit and the second time unit overlap in time, and at least one of the first signal and the second signal is an uplink synaesthesia signal or an uplink perception signal; when a sum of the first transmit power and the second transmit power is greater than a transmit power threshold, determining a third transmit power of the first signal in the first time unit based on a signal type of the first signal and a signal type of the second signal, the third transmit power being less than the first transmit power, or determining a fourth transmit power of the second signal in the second time unit, the fourth transmit power being less than the second transmit power; transmitting the first signal at the third transmit power in the first time unit on the first carrier, and transmitting the second signal at the second transmit power in the second time unit on the second carrier; or transmitting the first signal at the first transmit power in the first time unit on the first carrier, and transmitting the second signal at the fourth transmit power in the second time unit on the second carrier.

[0008] In a possible implementation, the method may be executed by a terminal device, or by a chip in the terminal device.

[0009] It should be understood that the first time unit and the second time unit partially or completely overlap in time, and this embodiment of the present application does not limit this.

[0010] It should be understood that the above-mentioned network device may include a first network device and a second network device, wherein the first network device may be a group of network devices, which may include one or more network devices; the second network device may be a group of network devices, which may include one or more network devices.

[0011] Exemplarily, the terminal device may send a first signal to the first network device in N first time units on the first carrier, and may send a second signal to the second network device in a second time unit on the second carrier.

[0012] In an embodiment of the present application, the terminal device can, based on the priority information of the signal types of the first signal and the second signal, if the priority of the first signal is lower than the priority of the second signal, the terminal device can reduce the first transmission power of the first signal to the third transmission power; if the priority of the second signal is lower than the priority of the first signal, the terminal device can reduce the second transmission power of the second signal to the fourth transmission power.

[0013] Exemplarily, the first signal may include an uplink perception signal, and the second signal may include an uplink communication signal. The priority of the uplink perception signal is higher than the priority of the uplink communication signal, and the terminal device may send the uplink communication signal to the first network device at the fourth transmission power; or, the priority of the uplink perception signal is lower than the priority of the uplink communication signal, and the terminal device may send the uplink perception signal to the second network device at the third transmission power.

[0014] Exemplarily, the first signal may include an uplink synesthesia signal, and the second signal may include an uplink communication signal. The priority of the uplink synesthesia signal is higher than the priority of the uplink communication signal, and the terminal device may send the uplink communication signal to the first network device at the fourth transmission power; or the priority of the uplink synesthesia signal is lower than the priority of the uplink communication signal, and the terminal device may send the uplink synesthesia signal to the second network device at the third transmission power.

[0015] Exemplarily, the first signal may include an uplink synaesthesia signal, and the second signal may include an uplink perception signal. The priority of the uplink synaesthesia signal is higher than the priority of the uplink perception signal, and the terminal device may send the uplink perception signal to the first network device at the fourth transmission power; or the priority of the uplink synaesthesia signal may also be lower than the priority of the uplink perception signal, and the terminal device may send the uplink synaesthesia signal to the second network device at the third transmission power.

[0016] The signal sending method of the embodiment of the present application, in the uplink multi-carrier communication perception integrated scenario, when the terminal device can simultaneously send any two different uplink signals among the uplink perception signal, the uplink synesthesia signal or the uplink communication signal on two different carriers, when the sum of the transmission power of the two uplink signals exceeds the transmission power threshold of the terminal device, the terminal device can reduce the transmission power of the uplink signal with lower priority according to the priority information of the two uplink signals, which is beneficial to improving the rate at which the terminal device sends uplink signals to the network device.

[0017] In combination with the first aspect, in certain implementations of the first aspect, the first signal includes the uplink perception signal, the second signal includes the uplink communication signal, the priority of the uplink perception signal is higher than the priority of the uplink communication signal, the first signal is sent at the first transmission power, and the second signal is sent at the fourth transmission power.

[0018] It should be understood that the uplink perception signal is a signal that is continuously transmitted over N first time units. If the transmit power of the signal is reduced in one of the time units, the performance of the uplink perception signal transmitted over the N first time units may not meet the performance requirements, resulting in a waste of the N first time units. Therefore, the priority of the uplink perception signal is higher than the priority of the uplink communication signal.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the first signal includes the uplink perception signal, and the second signal includes one or more of the following: a channel sounding reference signal SRS, a physical uplink shared channel PUSCH without an acknowledgement ACK, a PUSCH without a negative acknowledgement NACK, or a PUSCH without channel state information CSI; the priority of the first signal is higher than the priority of the second signal, the first signal is sent at the first transmit power, and the second signal is sent at the fourth transmit power.

[0020] In combination with the first aspect, in certain implementations of the first aspect, the first signal includes the uplink perception signal, and the second signal includes one or more of the following: a physical random access channel PRACH, a physical uplink shared channel PUCCH carrying ACK, a PUCCH carrying NACK, a PUCCH carrying CSI, a PUCCH carrying a communication protocol SR, a PUSCH carrying ACK, a PUSCH carrying NACK, or a PUSCH carrying CSI; the priority of the first signal is lower than the priority of the second signal, the first signal is sent at the third transmit power, and the second signal is sent at the second transmit power.

[0021] In combination with the first aspect, in certain implementations of the first aspect, the first signal includes the uplink synaesthesia signal, the second signal includes the uplink communication signal, the priority of the uplink synaesthesia signal is higher than the priority of the uplink communication signal, the first signal is sent at the first transmission power, and the second signal is sent at the fourth transmission power.

[0022] It should be understood that the above-mentioned uplink synaesthesia signal may have both communication and perception capabilities. In order to better protect the communication and perception capabilities of the network, the priority of the uplink synaesthesia signal is higher than the priority of the uplink communication signal.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the first signal includes the uplink synaesthesia signal, the second signal includes the uplink communication signal, the communication function of the uplink synaesthesia signal and the communication function of the uplink communication signal are different, if the priority of the communication function of the uplink synaesthesia signal is higher than the priority of the communication function of the uplink communication signal, then the priority of the first signal is higher than the priority of the second signal, the first signal is sent at the first transmission power, and the second signal is sent at the fourth transmission power; if the priority of the communication function of the uplink synaesthesia signal is lower than the priority of the communication function of the uplink communication signal, then the priority of the first signal is lower than the priority of the second signal, the first signal is sent at the third transmission power, and the second signal is sent at the second transmission power.

[0024] Exemplarily, the same communication function may mean that the uplink communication signal and the uplink communication signal are different. For example, if the uplink communication signal is a PUCCH carrying CSI and the uplink communication signal is a PUSCH carrying NACK, the uplink communication signal has a higher priority than the uplink communication signal.

[0025] For example, if the uplink sympathetic signal is an SRS and the uplink communication signal is a PUCCH carrying an ACK, the priority of the uplink communication signal is higher than the priority of the uplink sympathetic signal.

[0026] In combination with the first aspect, in certain implementations of the first aspect, the first signal includes the uplink synaesthesia signal, the second signal includes the uplink perception signal, the priority of the uplink synaesthesia signal is higher than the priority of the uplink perception signal, the first signal is sent at the first transmission power, and the second signal is sent at the fourth transmission power.

[0027] It should be understood that the above-mentioned uplink synaesthesia signal may have both communication and perception capabilities. In order to better protect and maintain the communication and perception capabilities of the network, the priority of the uplink synaesthesia signal is higher than the priority of the uplink perception signal.

[0028] In combination with the first aspect, in certain implementations of the first aspect, before determining the first transmission power of the first signal in the first time unit on the first carrier, it also includes: determining to send the first signal to the network device in N first time units on the first carrier, where N is an integer greater than 1; wherein, when the total power of the first signal in the N first time units is greater than the preset power threshold, the priority of the first signal is lower than the priority of the second signal; when the total power of the first signal in the N first time units is less than or equal to the preset power threshold, the priority of the first signal is higher than the priority of the second signal, and the total power of the first signal in the N first time units is: the sum of the transmission powers of the M first time units that have been sent, and the sum of the transmission powers of the first signals to be sent in NM first time units, where M is an integer greater than 0.

[0029] Exemplarily, the uplink perception signal or uplink synaesthesia signal needs to be continuously sent over N first time units to better maintain the signal perception capability. Therefore, the signal priority can be determined based on the total power of the signal over the N first time units.

[0030] In combination with the first aspect, in certain implementations of the first aspect, the first signal needs to be continuously sent on N1 first time units among the N first time units, and the preset power threshold satisfies the following formula: the preset power threshold is equal to the product of N1 and the first transmission power multiplied by a coefficient r; wherein r is a real number greater than 0 and less than 1, and N1 is an integer greater than 1.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the sending of the first signal at the third transmit power within the first time unit on the first carrier, and the sending of the second signal at the second transmit power within the second time unit on the second carrier, include: when the transmit power difference between the first transmit power and the third transmit power is less than or equal to a preset threshold, the sending of the first signal at the third transmit power within the first time unit on the first carrier, and the sending of the second signal at the second transmit power within the second time unit on the second carrier.

[0032] For example, the transmit power difference can be expressed as a logarithmic value. For example, if the first transmit power is 2 decibels (dB) and the third transmit power is 17 dB, the transmit power difference is 3 dB. Alternatively, the transmit power difference can be expressed as a linear value. For example, if the first transmit power is 0.05 W and the third transmit power is 0.03 watts (W), the transmit power difference is 0.02 W. The values ​​of the transmit power differences are all close to 0, exceeding a preset threshold for the transmit power difference.

Optionally, the signal transmitting device further comprises a memory.

[0036] In another implementation, the signal sending device is a chip configured in the terminal device. When the signal sending device is a chip configured in the terminal device, the communication interface may be an input / output interface.

[0037] In a fourth aspect, a processor is provided, comprising: an input circuit, an output circuit, and a processing circuit. The processing circuit is configured to receive a signal through the input circuit and transmit a signal through the output circuit, so that the processor executes the method of any possible implementation of the first aspect.

[0040] Optionally, there are one or more processors and one or more memories.

[0051] The technical solution in this application will be described below with reference to the accompanying drawings.

[0052] To facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects.

Of course, SCMA can also be called other names in the field of communications; further, the technical solutions of the embodiments of the present application can be applied to multi-carrier transmission systems that adopt non-orthogonal multiple access technology, such as orthogonal frequency division multiplexing (OFDM), filter bank multi-carrier (FBMC), generalized frequency division multiplexing (GFDM), filtered orthogonal frequency division multiplexing (F-OFDM) system, etc.

[0058] The application scenario of the embodiments of the present application is a communication and perception integration scenario. Figure 1 shows a schematic diagram of a communication system 100 of the embodiments of the present application. From the perspective of perception mode, it can include six sub-scenarios: (a) Terminal device sends and receives independently, including: terminal device 101 and perception target 102. (b) Terminal device A sends and terminal device B receives, including: terminal device 103, terminal device 104, and perception target 105. (c) Terminal device sends and network device receives, including: terminal device 106, network device 107, and perception target 108.

(f) Network device sends and terminal device receives, including: network device 114, terminal device 115, and perception target 116. The perceived targets are not limited to vehicles, low-altitude drones, and pedestrians, but also include other moving or stationary objects.

[0059] It should be understood that the aforementioned network device or terminal device may be configured with multiple antennas, which may include at least one transmitting antenna for sending signals and at least one receiving antenna for receiving signals. Furthermore, the network device or terminal device may additionally include a transmitter chain and a receiver chain. Those skilled in the art will appreciate that each may include multiple components related to signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, or antennas). Therefore, the network device and the terminal device may communicate using multi-antenna technology.

[0060] It should be understood that the communication system shown in Figure 1 is only a schematic diagram, and the above communication system may also include other terminal devices and network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1. The embodiments of the present application do not limit the number of network devices and terminal devices included in the communication system.

[0061] In the embodiment of the present application, the network device can be any device with wireless transceiver function. The network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in ​​a 5G, such as NR, system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc.

[0062] In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU may be responsible for processing non-real-time protocols and services, such as the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and / or the packet data convergence protocol (PDCP) layer. The DU may be responsible for processing physical layer protocols and real-time services. For example, it may implement the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. A DU can be connected to only one CU or to multiple CUs, and a CU can be connected to multiple DUs. Communication between the CU and DU can be achieved through the F1 interface. The AAU may implement some physical layer processing functions, RF processing, and active antenna related functions. Since the information of the RRC layer will eventually be delivered to the PHY layer and become the information of the PHY layer, or converted from the information of the PHY layer, therefore, in this architecture, high-layer signaling, such as RRC layer signaling, can also be considered to be sent by DU, or by DU+AAU.

[0063] It is understood that the network device may include one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be classified as a network device in an access network (RAN) or a network device in a core network (CN), which is not limited in this application.

[0064] In different systems, CU (or CU-CP, CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meanings. For example, in the O-RAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU (Open DU), CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples for description.

[0065] Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented through a software module, a hardware module, or a combination of a software module and a hardware module.

[0066] Network equipment provides services for cells, and terminal devices communicate with cells through transmission resources allocated by the network equipment (for example, frequency domain resources, or spectrum resources). The cell can belong to a macro base station (for example, a macro eNB or macro gNB), or to a base station corresponding to a small cell. Small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0068] The terminal device may be a device that provides voice / data connectivity to users, such as a handheld device or vehicle-mounted device with wireless connection function. At present, some examples of terminals may include: mobile phones, tablet computers, computers with wireless transceiver functions (such as laptops, PDAs, etc.), mobile internet devices (MIDs), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks or future evolved public land mobile communication networks (PLMNs). terminal equipment in network, PLMN, etc.

[0069] Wearable devices, also known as wearable smart devices, are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve full or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0070] Furthermore, terminal devices can also be end devices in the Internet of Things (IoT) system. IoT is a crucial component of future information technology development. Its primary technical feature is connecting objects to the Internet through communications technology, thereby enabling intelligent networks that interconnect humans and machines, and objects and things. IoT technology, for example, utilizes narrowband (NB) technology to achieve massive connectivity, deep coverage, and power-saving terminals.

[0071] In addition, terminal devices can also include sensors such as smart printers, train detectors, and gas stations.

The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application. As long as it is possible to communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be a terminal device or a network device, or a functional module in the terminal device or the network device that can call a program and execute the program.

[0074] Below, for ease of understanding, the terms involved in the embodiments of the present application are first introduced.

[0075] 1. Communication and perception integrated technology

[0076] Integrated communication and perception technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. The core concept of this technology is to add perception capabilities to mobile communication networks, building the ability to detect, track, and image targets. This allows communication and perception capabilities to be integrated into a single network, achieving harmonious coexistence and even mutual benefit.

[0077] Perception can generally be divided into two modes: single-station perception and dual-station perception. In single-station perception, the transmitter and receiver of the perception signal are the same device. In terms of the perception signal process, the sensing station must both transmit the perception signal and receive the signal reflected from the target surface. Therefore, the single-station perception mode is also called the self-transmitting, self-receiving mode. In dual-station perception, the transmitter and receiver of the perception signal are two different devices. In terms of the perception signal process, after sensing device A transmits the perception signal, the signal reflected from the target surface is received by sensing device B. Therefore, the dual-station perception mode is also called the sensing device A transmits, sensing device B receives mode.

[0078] Communication involves a transmitting device modulating information onto radio waves and sending them to a receiving device. The receiving device then demodulates the signal carried on the radio waves to retrieve the information. Perception, on the other hand, requires a transmitting device to send radio waves in a specific direction. When these waves strike a target surface, they reflect back to the receiving device, which then processes the reflected waves to obtain information such as the target's location, speed, and type. This shows that the technical principles of perception differ from those of communication.

[0079] 2. Wireless communication air interface technology

[0080] In wireless communication systems, communications can be categorized into different types based on the types of sending and receiving nodes. Typically, downlink communication refers to sending information from a network device to a terminal device, while uplink communication refers to sending information from a terminal device to a network device.

[0081] In LTE / long term evolution advanced (LTE-A) communication systems and NR systems, they can be mainly divided into FDD mode and TDD mode according to the different duplex modes. For wireless communication systems operating in TDD mode, the downlink carrier and uplink carrier of the system are carriers of the same carrier frequency. For wireless communication systems operating in FDD mode, the downlink carrier and uplink carrier of the system are carriers of different frequencies.

[0082] Multiple access typically uses orthogonal frequency division multiplexing access (OFDMA). OFDMA divides transmission resources into orthogonal time-frequency resource elements (REs). Signals from the transmitting device are carried on the REs and transmitted to the receiving device. Because the REs are orthogonal to each other, the receiving device can receive the signal from each RE individually.

[0083] With the continuous development of communication systems, terminal devices support simultaneous access to two network devices. This access mode is called dual connectivity (DC), where one network device is the primary network device and the other network device is the secondary network device. The one or more cells that the primary network device provides services to the terminal device are called a master cell group (MCG), and the one or more cells that the secondary network device provides services to the terminal device are called a secondary cell group (SCG).

[0084] During the evolution of wireless communication systems, terminal devices can support simultaneous access to two different radio access systems. For example, operators will deploy both NR and LTE systems, and terminal devices can also support simultaneous access to LTE and NR network devices. Because LTE is also known as evolved universal terrestrial radio access (E-UTRA), this access method is called evolved universal terrestrial radio access with new air interface dual connectivity (EN-DC). In EN-DC mode, LTE network devices are primary network devices, and NR network devices are secondary network devices.

[0085] Of course, as the system evolves, it will also support new air interface and evolved universal terrestrial radio access dual connectivity (NE-DC) in the future, that is, NR network equipment is the primary network equipment, and LTE network equipment is the secondary network equipment. Since both EN-DC and NE-DC terminals will access network equipment with two different radio access technologies, these DC modes can also be collectively referred to as multi-radio access technology dual connectivity (MR-DC). In addition, for terminal devices that only support NR, they can also access two different NR network devices at the same time. This type of connection is called NR-NR DC.

[0086] To increase the rate at which terminal devices send uplink signals to network devices, terminal devices operating in DC mode can send uplink signals to network devices on carriers in both the MCG and SCG simultaneously within the same time period. However, the total power of uplink signals sent by the terminal device on all carriers cannot exceed the preset threshold for the terminal device's transmit power. Therefore, if the total power of uplink signals sent by the terminal on carriers in the MCG and SCG exceeds the maximum transmit power, the terminal device needs to actively reduce the transmit power on one or more carriers.

[0087] At present, some terminal devices can determine the priority of the signal according to the signal type of the uplink communication signal sent on the carrier in the MCG and SCG in the same time period, and reduce the transmission power of the signal with low priority. For example, the signal type of the uplink communication signal may include, in order of priority: a physical uplink control channel (PUCCH) carrying an acknowledgement (ACK), a negative acknowledgement (NACK), and a communication protocol (selective repeat, SR), a physical uplink shared channel (PUSCH) carrying ACK and NACK, a PUCCH carrying channel state information CSI, a PUSCH carrying CSI, a PUSCH not carrying ACK, NACK or CSI, and a sounding reference signal (SRS). If the terminal device sends the same signal type on the two CGs, the transmission power of the signal on the SCG can be reduced based on the fact that the priority of the signal on the MCG is higher than that of the signal on the SCG.

[0088] However, the signal transmission method of the above-mentioned terminal device cannot effectively control the transmission power of the uplink signal in the uplink multi-carrier communication perception integrated scenario, which may reduce the rate at which the terminal device sends uplink signals to the network device.

[0089] In view of this, an embodiment of the present application provides a signal sending method. In an uplink multi-carrier communication perception integrated scenario, a terminal device can simultaneously send any two uplink signals among uplink perception signals, uplink communication signals or uplink communication signals on two different carriers. When the sum of the transmission powers of the two uplink signals exceeds the transmission power threshold of the terminal device, the transmission power of the uplink signal with lower priority can be reduced according to the priority information of the two uplink signals, thereby facilitating improving the rate at which the terminal device sends uplink signals to the network device.

[0090] The signal transmission method and apparatus provided by the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the technical solution of the present application can be applied to wireless communication systems.

[0091] For example, the communication system 100 shown in Figure 1. Two communication devices in the wireless communication system may have a wireless communication connection relationship, and one of the two communication devices may correspond to the self-transmitting and self-receiving terminal device in Figure 1(a), for example, it may be the terminal device itself or a chip configured in the terminal device.

[0092] One of the two communication devices may also correspond to the terminal device in Figure 1(b), which may be the terminal device itself or a chip configured in the terminal device; the other communication device of the two communication devices may correspond to the terminal device shown in Figure 1(b), such as, it may be the terminal device itself or a chip configured in the terminal device.

[0093] One of the two communication devices may also correspond to the terminal device shown in Figure 1(c), for example, it may be the terminal device itself or a chip configured in the terminal device; the other of the two communication devices may correspond to the network device shown in Figure 1(c), for example, it may be the network device itself or a chip configured in the network device.

[0094] One of the two communication devices may correspond to the self-transmitting and self-receiving network device in FIG. 1( d ), for example, it may be the network device itself, or a chip configured in the network device.

[0095] One of the two communication devices may also correspond to the network device in Figure 1(e), which may be the network device itself or a chip configured in the network device; the other communication device among the two communication devices may correspond to the network device shown in Figure 1(e), such as, it may be the network device itself or a chip configured in the network device.

[0096] One of the two communication devices may also correspond to the network device shown in Figure 1(f), for example, it may be the network device itself or a chip configured in the network device; the other of the two communication devices may correspond to the terminal device shown in Figure 1(f), for example, it may be the terminal device itself or a chip configured in the terminal device.

[0097] Below, without loss of generality, the signal transmission method provided in the embodiment of the present application is described in detail by taking the terminal device as the sending device and the network device as the receiving device as an example.

[0098] In this application, "sending a signal to a network device" should be understood to mean that the destination of the signal is the network device, and may include sending information to the network device directly or indirectly. The information may undergo necessary processing between the source and destination, but the destination can still understand the valid information from the source. Similar expressions in this application should be understood similarly and will not be repeated here.

[0099] FIG2 shows a signal sending method 200 provided in an embodiment of the present application. The method 200 includes the following steps:

[0100] S201, the terminal device determines a first transmission power of a first signal within a first time unit on a first carrier, and determines a second transmission power of a second signal within a second time unit on a second carrier, wherein the first time unit and the second time unit overlap in time, and at least one of the first signal and the second signal is an uplink synaesthesia signal or an uplink perception signal.

[0101] It should be understood that the first time unit and the second time unit partially or completely overlap in time, and this embodiment of the present application does not limit this.

[0102] S202, when the sum of the first transmit power and the second transmit power is greater than the transmit power threshold, the terminal device determines the third transmit power of the first signal within the first time unit based on the signal type of the first signal and the signal type of the second signal, and the third transmit power is less than the first transmit power, or determines the fourth transmit power of the second signal within the second time unit, and the fourth transmit power is less than the second transmit power.

[0103] S203, the terminal device sends a first signal at a third transmission power within a first time unit on the first carrier, and sends a second signal to the network device at a second transmission power within a second time unit on the second carrier; or, sends a first signal at a first transmission power within a first time unit on the first carrier, and sends a second signal to the network device at a fourth transmission power within a second time unit on the second carrier.

[0104] It should be understood that the above-mentioned network device may include a first network device and a second network device, wherein the first network device may be a group of network devices, which may include one or more network devices; the second network device may be a group of network devices, which may include one or more network devices.

[0105] Exemplarily, the terminal device may send a first signal to the first network device in N first time units on the first carrier, and may send a second signal to the second network device in a second time unit on the second carrier.

[0106] In an embodiment of the present application, the terminal device can, based on the priority information of the signal types of the first signal and the second signal, if the priority of the first signal is lower than the priority of the second signal, the terminal device can reduce the first transmission power of the first signal to the third transmission power; if the priority of the second signal is lower than the priority of the first signal, the terminal device can reduce the second transmission power of the second signal to the fourth transmission power.

[0107] Exemplarily, the first signal may include an uplink perception signal, and the second signal may include an uplink communication signal. The priority of the uplink perception signal is higher than the priority of the uplink communication signal, and the terminal device may send the uplink communication signal to the first network device at the fourth transmission power; or, the priority of the uplink perception signal is lower than the priority of the uplink communication signal, and the terminal device may send the uplink perception signal to the second network device at the third transmission power.

[0108] Exemplarily, the first signal may include an uplink synesthesia signal, and the second signal may include an uplink communication signal. The priority of the uplink synesthesia signal is higher than the priority of the uplink communication signal, and the terminal device may send the uplink communication signal to the first network device at the fourth transmission power; or the priority of the uplink synesthesia signal is lower than the priority of the uplink communication signal, and the terminal device may send the uplink synesthesia signal to the second network device at the third transmission power.

[0109] Exemplarily, the first signal may include an uplink synaesthesia signal, and the second signal may include an uplink perception signal. The priority of the uplink synaesthesia signal is higher than the priority of the uplink perception signal, and the terminal device may send the uplink perception signal to the first network device at the fourth transmission power; or the priority of the uplink synaesthesia signal may also be lower than the priority of the uplink perception signal, and the terminal device may send the uplink synaesthesia signal to the second network device at the third transmission power.

[0110] The signal sending method of the embodiment of the present application, in the uplink multi-carrier communication perception integrated scenario, when the terminal device can simultaneously send any two different uplink signals among the uplink perception signal, the uplink synesthesia signal or the uplink communication signal on two different carriers, when the sum of the transmission power of the two uplink signals exceeds the transmission power threshold of the terminal device, the terminal device can reduce the transmission power of the uplink signal with lower priority according to the priority information of the two uplink signals, which is beneficial to improving the rate at which the terminal device sends uplink signals to the network device.

[0111] It should be understood that the above-mentioned time unit can be a millisecond, a subframe, a time slot, a mini-time slot, a symbol or multiple consecutive symbols, and the embodiments of the present application are not limited to this.

[0112] For example, a time slot in the NR system may include 14 OFDM symbols, the time slot length corresponding to the 15kHz subcarrier spacing is 1ms, and the time slot length corresponding to the 30kHz subcarrier spacing is 0.5ms; the time length of a subframe in the NR system is 1ms.

[0113] It should also be understood that the first carrier and the second carrier are different carriers.

[0114] Optionally, the first carrier and the second carrier may belong to the same group of network devices, such as, the first carrier and the second carrier may belong to the same MCG, or the same SCG; the first carrier and the second carrier may also belong to different groups of network devices, such as, the first carrier and the second carrier may belong to MCG and SCG respectively, or the first carrier and the second carrier may belong to two different SCGs respectively, or the first carrier and the second carrier may belong to two different MCGs respectively. This embodiment of the present application is not limited to this.

[0115] Optionally, the first carrier and the second carrier may belong to the same radio access technology, such as, the first carrier and the second carrier are both NR carriers, or both are LTE carriers, or both are 6G carriers; the first carrier and the second carrier may also belong to different radio access technologies, such as, the first carrier and the second carrier are respectively NR and LTE carriers, or respectively NR and 6G carriers, or respectively LTE and 6G carriers. This embodiment of the present application is not limited to this.

[0116] It should be understood that the above-mentioned priority information can be reflected in a variety of different ways. In one possible implementation, the above-mentioned priority can correspond to a priority value. For example, the lower the priority value, the higher the corresponding priority. Or, the higher the priority value, the higher the corresponding priority. Taking the lower the priority value, the higher the corresponding priority as an example, if the value range of the priority value can be an integer from 1 to 2, then when the priority value is 1, it represents the highest priority. It should be understood that the priority value with a value range of 1 to 2 is shown here only for ease of understanding, but this should not constitute any limitation to this application. This application does not impose any limitation on the specific value range of the priority value. For example, the value range can also be an integer from 0 to 2. In another possible implementation, the above-mentioned priority can also be characterized by priority levels, such as high priority, medium priority and low priority, which are not limited in the embodiments of the present application.

[0117] Optionally, in an embodiment of the present application, before S201, the terminal device may determine to send a first signal to the first network device within N first time units on the first carrier, where N is an integer greater than 1; the terminal device may also determine to send a second signal to the second network device within a second time unit on the second carrier.

[0118] Among them, when the total power of the first signal on N first time units is greater than the preset power threshold, the priority of the first signal is lower than that of the second signal; when the total power of the first signal on N first time units is less than or equal to the preset power threshold, the priority of the first signal is higher than the priority of the second signal, and the total power of the first signal on N first time units is: the sum of the transmission power of the M first time units that have been completed, and the sum of the transmission power of the first signals to be sent on NM first time units.

[0119] Exemplarily, the uplink perception signal or uplink synaesthesia signal needs to be continuously sent over N first time units to better maintain the signal perception capability. Therefore, the signal priority can be determined based on the total power of the signal over the N first time units.

[0120] It should be understood that the above-mentioned preset power threshold is equal to the product of N1 and the first transmission power multiplied by a coefficient r, where r is a real number greater than 0 and less than 1.

[0121] Optionally, in one possible case, when the transmission power difference between the first transmission power and the third transmission power is less than or equal to a preset threshold, a first signal is sent to the first network device at the third transmission power within a first time unit on the first carrier, and a second signal is sent to the second network device at the second transmission power within a second time unit on the second carrier.

[0122] In another possible case, when the transmission power difference between the first transmission power and the third transmission power of the first signal is greater than a preset threshold, the terminal device may not send the first signal to the network device; or, when the transmission power difference between the second transmission power and the fourth transmission power of the second signal is greater than the preset threshold of the transmission power difference, the terminal device may not send the second signal to the network device.

[0123] For example, the transmit power difference can be expressed as a logarithmic value. For example, if the first transmit power is 2 decibels (dB) and the third transmit power is 17 dB, the transmit power difference is 3 dB. Alternatively, the transmit power difference can be expressed as a linear value. For example, if the first transmit power is 0.05 W and the third transmit power is 0.03 watts (W), the transmit power difference is 0.02 W. The values ​​of the transmit power differences are all close to 0, exceeding a preset threshold for the transmit power difference.

[0124] In an embodiment of the present application, a terminal device may transmit a first signal to a first network device at a first transmit power, and may transmit a second signal to a second network device at a second transmit power. When the sum of the first transmit power and the second transmit power exceeds a transmit power threshold of the terminal device, the transmit power of the lower-priority signal may be reduced based on priority information of the two signals. The first signal and the second signal are different signals.

[0125] Exemplarily, the following specifically introduces three possible ways in which, when the first signal and the second signal are different signals, the terminal device can reduce the transmission power of the signal with the lower priority according to the priority information of the two signals.

[0126] Method 1: If the first signal is an uplink sensing signal, the second signal is an uplink communication signal.

[0127] In one possible implementation, the uplink perception signal has a higher priority than the uplink communication signal. In this case, the terminal device can reduce the second transmission power of the uplink communication signal to the fourth transmission power. Therefore, the terminal device can send the uplink perception signal to the first network device at the first transmission power, and can send the uplink communication signal to the second network device at the fourth transmission power.

[0128] It should be understood that the uplink perception signal is a signal that is continuously transmitted over N first time units. If the transmit power of the signal is reduced in one of the time units, the performance of the uplink perception signal transmitted over the N first time units may not meet the performance requirements, resulting in a waste of the N first time units. Therefore, the priority of the uplink perception signal is higher than the priority of the uplink communication signal.

[0129] In another possible implementation, when the above-mentioned uplink communication signal is any one of the channel sounding reference signal SRS, the physical uplink shared channel PUSCH without carrying an affirmative acknowledgement ACK, the PUSCH without carrying a negative acknowledgement NACK, or the PUSCH without carrying channel state information CSI, the priority of the uplink perception signal is higher than the priority of the uplink communication signal. In this case, the terminal device can reduce the second transmission power of the above-mentioned uplink communication signal to the fourth transmission power. Therefore, the terminal device can send the uplink perception signal to the first network device at the first transmission power, and can send the uplink communication signal to the second network device at the fourth transmission power.

[0130] In another possible implementation, when the uplink communication signal is any one of a physical random access channel PRACH, a physical uplink shared channel PUCCH carrying ACK, a PUCCH carrying NACK, a PUCCH carrying CSI, a PUCCH carrying a communication protocol SR, a PUSCH carrying ACK, a PUSCH carrying NACK, or a PUSCH carrying CSI, the priority of the uplink perception signal is lower than the priority of the uplink communication signal. In this case, the terminal device can reduce the first transmit power of the uplink perception signal to a third transmit power. Therefore, the terminal device can send the uplink perception signal to the first network device at the third transmit power, and can send the uplink communication signal to the second network device at the second transmit power.

[0131] Mode 2: If the first signal is an uplink synaesthesia signal, the second signal is an uplink communication signal.

[0132] In one possible implementation, the priority of the uplink synesthesia signal is higher than the priority of the uplink communication signal. In this case, the terminal device can reduce the second transmission power of the uplink communication signal to the fourth transmission power. Therefore, the terminal device can send the uplink synesthesia signal to the first network device at the first transmission power, and can send the uplink communication signal to the second network device at the fourth transmission power.

[0133] It should be understood that the above-mentioned uplink synaesthesia signal may have both communication and perception capabilities. In order to better protect the communication and perception capabilities of the network, the priority of the uplink synaesthesia signal is higher than the priority of the uplink communication signal.

[0134] In another possible implementation, the uplink synesthesia signal and the uplink communication signal have the same communication function, and the priority of the uplink synesthesia signal is higher than the priority of the uplink communication signal. In this case, the terminal device can reduce the second transmission power of the uplink communication signal to the fourth transmission power. Therefore, the terminal device can send the uplink synesthesia signal to the first network device at the first transmission power, and can send the uplink communication signal to the second network device at the fourth transmission power.

[0135] For example, the same communication function may mean that the uplink synaptic signal and the uplink communication signal are the same, and both can be any of a PUCCH carrying ACK, NACK, or SR, a PUSCH carrying ACK or NACK, a PUCCH carrying CSI, a PUSCH carrying CSI, a PUSCH not carrying ACK, NACK, or CSI, or an SRS. The uplink synaptic signal has a sensing capability. In this case, the priority of the uplink synaptic signal is higher than the priority of the uplink communication signal.

[0136] It should be understood that the above signals are listed in order of priority from high to low.

[0137] In another possible implementation, the communication function of the uplink synaesthesia signal and the communication function of the uplink communication signal are different. If the priority of the communication function of the uplink synaesthesia signal is higher than the priority of the communication function of the uplink communication signal, the terminal device can send the uplink synaesthesia signal to the first network device at a first transmission power, and can send the uplink communication signal to the second network device at a fourth transmission power; or, if the priority of the communication function of the uplink synaesthesia signal is lower than the priority of the communication function of the uplink communication signal, the terminal device can send the uplink synaesthesia signal to the first network device at a third transmission power, and can send the uplink communication signal to the second network device at a second transmission power.

[0138] Exemplarily, the above-mentioned same communication function may mean that the uplink synesthesia signal and the uplink communication signal are different. For example, the uplink synesthesia signal is a PUCCH carrying CSI, and the uplink communication signal is a PUSCH carrying NACK, then the priority of the uplink synesthesia signal is higher than the priority of the uplink communication signal; for example, the uplink synesthesia signal is an SRS, and the uplink communication signal is a PUCCH carrying ACK, then the priority of the uplink communication signal is higher than the priority of the uplink synesthesia signal.

[0139] Mode 3: If the first signal is an uplink synaesthesia signal, the second signal is an uplink perception signal.

[0140] In one possible implementation, the priority of the uplink synesthesia signal is higher than the priority of the uplink perception signal. In this case, the terminal device can reduce the second transmission power of the uplink perception signal to the fourth transmission power. Therefore, the terminal device can send the uplink synesthesia signal to the first network device at the first transmission power, and can send the uplink perception signal to the second network device at the fourth transmission power.

[0141] It should be understood that the above-mentioned uplink synaesthesia signal may have both communication and perception capabilities. In order to better protect and maintain the communication and perception capabilities of the network, the priority of the uplink synaesthesia signal is higher than the priority of the uplink perception signal.

[0142] In another possible implementation, the priority of the uplink synesthesia signal is lower than the priority of the uplink perception signal. In this case, the terminal device can reduce the second transmission power of the uplink synesthesia signal to the fourth transmission power. Therefore, the terminal device can send the uplink synesthesia signal to the first network device at the third transmission power, and can send the uplink perception signal to the second network device at the second transmission power.

[0143] Exemplarily, the uplink synesthesia signal is SRS, and the uplink perception signal is PUSCH, then the priority of the uplink perception signal is higher than the priority of the uplink synesthesia signal.

[0144] The signal sending method of the embodiment of the present application, in the uplink multi-carrier communication perception integrated scenario, the terminal device can simultaneously send any two different uplink signals among the uplink perception signal, the uplink communication signal or the uplink communication signal to the first network device and the second network device on two different carriers. When the sum of the transmission power of the two uplink signals exceeds the transmission power threshold of the terminal device, the terminal device can reduce the transmission power of the uplink signal with lower priority according to the priority information of the two uplink signals, which is conducive to improving the rate at which the terminal device sends uplink signals to the network device.

[0145] The signal sending method according to an embodiment of the present application is described in detail above in conjunction with Figures 1 to 2. The signal sending device according to an embodiment of the present application will be described in detail below in conjunction with Figures 3 and 4.
