Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to power control methods, devices and systems. Background Technology

[0002] Uplink power control specifically refers to controlling and adjusting the uplink transmit power of terminal devices. Uplink power control is crucial in wireless communication systems. By properly adjusting the uplink transmit power of terminal devices, it is possible to minimize the transmit power of terminal devices while ensuring the quality of the received signal on the receiving side, thereby extending the battery life of terminal devices, and also to minimize uplink interference to other terminal devices in the system.

[0003] Based on the significance of uplink power control mentioned above, most companies have already supported uplink power control at the 3rd generation partnership project (3GPP) standards meeting 1#102-e for radio access network (RAN).

[0004] Currently, for problems other than positioning, uplink power control only needs to consider the measurement results obtained by the serving base station of the terminal device from measuring the uplink reference signal sent by the terminal device. This is because the uplink reference signal sent by the terminal device is useless to the neighboring base stations of the terminal device. However, in positioning problems, all base stations participating in the positioning of the terminal device need to receive and measure the uplink reference signal sent by the terminal device. In other words, in positioning problems, the uplink reference signal sent by the terminal device is useful to all base stations participating in the positioning of the terminal device (including the serving base station and neighboring base stations). Therefore, uplink power control is an important issue that requires further research in current positioning problems. Summary of the Invention

[0179] To facilitate understanding of the solutions in the embodiments of this application, a brief introduction or definition of the relevant technologies is given below:

[0180] First, the positioning sounding reference signal (pos-SRS):

[0181] pos-SRS is an uplink positioning reference signal specifically for positioning, proposed in version 16 (R16).

[0182] Second, the sounding reference signal (SRS):

[0183] Unless otherwise specified, SRS refers to the uplink reference signal used in version 15 (R15) and earlier versions for multiple-input multiple-output (MIMO), i.e., MIMO-SRS. Furthermore, positioning methods in R15 and earlier versions can also use this reference signal for positioning, such as observed time difference of arrival (OTDOA) positioning.

[0184] Third, open-loop power control and closed-loop power control:

[0185] Power control is categorized into open-loop power control and closed-loop power control based on whether both the base station and the terminal device participate simultaneously. Closed-loop power control is further divided into inner-loop power control and outer-loop power control. The process of establishing a connection between the open-loop and closed-loop control involves a process. Before the terminal device and the base station establish a connection, the terminal device is not controlled by the base station and adjusts its uplink transmit power through its own measurements—this is open-loop power control. Once the connection is established, the base station can control the uplink transmit power of the terminal device, thus forming a control loop. Therefore, power control at this stage is called closed-loop power control.

[0186] The following section introduces open-loop power control and closed-loop power control.

[0187] Under open-loop power control, the terminal device assumes that the uplink and downlink path losses are approximately equal. The terminal device estimates the downlink path loss by measuring the received power of the downlink reference signal, and thus calculates the uplink transmit power. Therefore, open-loop power control is unidirectional and not closed-loop. That is, open-loop power control does not require feedback information from the receiver; instead, it controls power based on its own measurements.

[0188] Under closed-loop power control, the transmitting end needs to control the uplink transmit power of the terminal equipment based on the feedback information sent by the receiving end. Closed-loop power control is divided into outer-loop power control and inner-loop power control.

[0189] In inner-loop power control, both the base station and the terminal equipment participate in uplink power control. Specifically, the base station, based on the power headroom report (PHR) received from the terminal equipment and the measurement results obtained from measuring the uplink reference signal sent by the terminal equipment, combines the target measurement results with the power control algorithm to determine the adjustment value of the uplink transmit power of the terminal equipment, and then sends an uplink power control (TPC) command to the terminal equipment. After receiving the TPC command, the terminal equipment determines its uplink transmit power according to the adjustment value of the uplink transmit power in the TPC command.

[0190] Outer-loop power control is used by the base station to determine the target measurement result of inner-loop power control based on factors such as the service quality or service priority of the terminal equipment. For example, if the target measurement result includes the target signal-to-interference-plus-noise ratio (SINR), the base station can obtain the block error rate (BLER) through cyclic redundancy check (CRC). When the BLER is lower than the target BLER, the target SINR can be increased accordingly through the outer-loop power control algorithm. The target BLER is related to the required service quality.

[0191] It should be noted that inner-loop power control is a fast power control process, adjusting once per subframe, while outer-loop power control is a slow power control process, typically occurring once every few hundred milliseconds. Subsequent embodiments of this application mainly involve inner-loop power control under closed-loop power control; open-loop power control and outer-loop power control under closed-loop power control are not specifically described. This will be explained uniformly here and will not be repeated below.

[0192] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0193] The technical solutions of this application can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5th Generation (5G) systems, or New Radio (NR), etc. The 5G mobile communication systems involved in this application include non-standalone (NSA) 5G mobile communication systems and standalone (SA) 5G mobile communication systems. The technical solutions provided in this application can also be applied to future communication systems, such as 6th Generation (6G) mobile communication systems. The communication system can also be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT) communication system, or other communication systems.

[0194] Figure 1 This is a schematic diagram of the architecture of a power control system applying the power control method provided in the embodiments of this application. Figure 1 As shown, the power control system includes a first access network device, one or more second access network devices, and a positioning management device. The first access network device is the serving access network device for the terminal device participating in the positioning process, and the second access network devices are neighboring cell access network devices for the terminal device participating in the positioning process. The positioning management device can communicate directly with the first or second access network device, or it can communicate through forwarding from other devices; this embodiment does not specifically limit this. Although not shown, the power control system may also include other functions or modules such as mobility management functions; this embodiment does not specifically limit this.

[0195] In one possible implementation, after receiving second power adjustment assistance information sent by one or more second access network devices, the positioning management device sends first power adjustment assistance information to the first access network device. The first power adjustment assistance information is determined by the positioning management device based on the second power adjustment assistance information sent by the one or more second access network devices. The first access network device receives the first power adjustment assistance information from the positioning management device, determines power adjustment information based on the first power adjustment assistance information, and then sends power adjustment information to the terminal device. This power adjustment information is used by the terminal device to adjust its uplink transmit power. Detailed implementation of this scheme will be described in subsequent method embodiments and will not be elaborated here. In positioning problems, the reference signal sent by the terminal device is useful to all access network devices participating in the terminal device's positioning; that is, all access network devices participating in the terminal device's positioning need to measure the reference signal sent by the terminal device. In the scheme provided in this application embodiment, the power adjustment information determined by the first access network device takes into account the first power adjustment assistance information sent by the positioning management device. The first power adjustment assistance information is determined by the positioning management device based on the second power adjustment assistance information sent by one or more second access network devices. That is, in the embodiments of this application, the power adjustment information used by the terminal device to adjust the uplink transmission power is determined based on the second power adjustment auxiliary information provided by the neighboring cell access network device of the terminal device participating in the positioning of the terminal device. Therefore, it meets the requirements of the positioning problem and can realize uplink power control in the positioning process.

[0196] In another possible implementation, the positioning management device receives second power adjustment assistance information sent by one or more second access network devices; and the positioning management device receives third power adjustment assistance information sent by a first access network device. Then, after determining first power adjustment assistance information based on the third power adjustment assistance information and the second power adjustment assistance information sent by one or more second access network devices, the positioning management device sends the first power adjustment assistance information to the first access network device. The first access network device receives the first power adjustment assistance information from the positioning management device, and after determining power adjustment information based on the first power adjustment assistance information, sends power adjustment information to the terminal device. This power adjustment information is used by the terminal device to adjust its uplink transmit power. Detailed implementation of this scheme will be described in subsequent method embodiments and will not be elaborated here. In positioning problems, the reference signal sent by the terminal device is useful to all access network devices participating in the positioning of the terminal device; that is, all access network devices participating in the positioning of the terminal device need to measure the reference signal sent by the terminal device. In the scheme provided in this application embodiment, the power adjustment information determined by the first access network device takes into account the first power adjustment assistance information sent by the positioning management device. The first power adjustment assistance information is determined by the positioning management device based on the second power adjustment assistance information sent by one or more second access network devices. That is, in the embodiments of this application, the power adjustment information used by the terminal device to adjust the uplink transmit power is determined based on the second power adjustment assistance information provided by the neighboring access network devices of the terminal device participating in the positioning of the terminal device. Therefore, it meets the requirements of the positioning problem and can realize uplink power control in the positioning process.

[0197] In another possible implementation, the positioning management device receives second power adjustment assistance information sent by one or more second access network devices; and the positioning management device receives third power adjustment assistance information sent by the first access network device. Then, after determining power adjustment information based on the third power adjustment assistance information and the second power adjustment assistance information sent by one or more second access network devices, the positioning management device sends the power adjustment information to the terminal device or sends the power adjustment information to the terminal device through the first access network device. This power adjustment information is used by the terminal device to adjust its uplink transmit power. Detailed implementation of this scheme will be described in subsequent method embodiments and will not be elaborated here. In positioning problems, the reference signal sent by the terminal device is useful to all access network devices participating in the positioning of the terminal device; that is, all access network devices participating in the positioning of the terminal device need to measure the reference signal sent by the terminal device. In the scheme provided in this application embodiment, the power adjustment information determined by the positioning management device takes into account the second power adjustment assistance information sent by one or more second access network devices and the third power adjustment assistance information sent by the first access network device. That is, in the embodiments of this application, the power adjustment information used by the terminal device to adjust the uplink transmission power is determined based on the second power adjustment auxiliary information provided by the neighboring cell access network device of the terminal device participating in the positioning of the terminal device and the third power adjustment auxiliary information provided by the serving access network device of the terminal device. Therefore, it meets the requirements of the positioning problem and can realize uplink power control in the positioning process.

[0198] Figure 2 A schematic diagram of the architecture of another power control system applying the power control method provided in the embodiments of this application. (See diagram below.) Figure 2 As shown, the power control system includes a first access network device and one or more second access network devices. The first access network device is the serving access network device for the terminal device participating in the terminal device positioning, and the second access network devices are neighboring cell access network devices for the terminal device participating in the terminal device positioning. Although not shown, the power control system may also include other functions or modules such as positioning management devices or mobility management functions; this embodiment does not specifically limit these features.

[0199] In one possible implementation, after acquiring the second power adjustment assistance information, the second access network device sends the second power adjustment assistance information to the first access network device. After receiving the second power adjustment assistance information sent by one or more second access network devices, the first access network device determines power adjustment information based on the second power adjustment assistance information sent by the one or more second access network devices, and sends the power adjustment information to the terminal device. This power adjustment information is used by the terminal device to adjust its uplink transmit power. Detailed implementation of this scheme will be described in subsequent method embodiments and will not be elaborated here. In the positioning problem, the reference signal sent by the terminal device is useful to all access network devices participating in the terminal device positioning; that is, all access network devices participating in the terminal device positioning need to measure the reference signal sent by the terminal device. In the scheme provided in this application embodiment, the power adjustment information used by the terminal device to adjust its uplink transmit power is determined based on the second power adjustment assistance information provided by the neighboring access network devices of the terminal device participating in the terminal device positioning. Therefore, it meets the requirements of the positioning problem and can realize uplink power control in the positioning process.

[0200] It should be understood that, in the embodiments of this application, the reference signal sent by the terminal device specifically refers to the uplink reference signal, which will be uniformly explained here and will not be repeated below.

[0201] Optionally, the power control system provided in this application embodiment can be applied to the various communication systems described above. Taking a 5G mobile communication system as an example, Figure 1 or Figure 2 The functions or network elements corresponding to the access network equipment (including the first access network equipment or the second access network equipment) in the 5G mobile communication system can be next-generation radio access network (NG-RAN) equipment. The functions or network elements corresponding to the location management equipment can be the location management function (LMF) or location management component (LMC) in the 5G mobile communication system, or the local location management function (LLMF) located in the NG-RAN equipment. The functions or network elements corresponding to the mobility management function can be the access and mobility management function (AMF) in the 5G mobile communication system. This application embodiment does not specifically limit these aspects.

[0202] For example, Figure 3 or Figure 4This diagram illustrates the relationship between the terminal device, NG-RAN device, LMF, and AMF when applying the power control method of this application in a 5G mobile communication system. Figure 3 As shown, the terminal equipment connects to the radio access network via the LTE-Uu and / or NR-Uu interfaces through next-generation evolved NodeB (ng-eNB) and generation node B (gNB); the radio access network connects to the core network via the AMF through the NG-C interface. NG-RAN includes one or more ng-eNBs ( Figure 3 (Taking one ng-eNB as an example for illustration); NG-RAN can also include one or more gNBs ( Figure 3 (Taking a gNB as an example for illustration); NG-RAN can also include one or more ng-eNBs and one or more gNBs. An ng-eNB is an LTE base station accessing the 5G core network, and a gNB is a 5G base station accessing the 5G core network. The core network includes the AMF and LMF. The AMF is used to implement access management functions, while the LMF interacts with terminal equipment or NG-RAN equipment to implement various functions (such as positioning or power control). The AMF and LMF are connected via the NLs interface. Figure 4 and Figure 3 Similarly, the difference lies in: Figure 3 The positioning management function devices or components (such as LMF) are deployed in the core network. Figure 4 Location management devices or components (such as LMC) can be deployed in NG-RAN equipment. For example... Figure 4 As shown, the gNB contains the LMC. The LMC is a functional component of the LMF and can be integrated into the gNB of NG-RAN equipment.

[0203] It should be understood that Figure 3 or Figure 4 NG-RAN equipment in the middle can provide Figure 1 or Figure 2 The first access network device in the network can also be Figure 1 or Figure 2 Any of the second access network devices in it. Figure 3 This is merely an illustrative diagram showing the relationship between the terminal device, NG-RAN device, LMF, and AMF when the power control method of this application is applied in a 5G mobile communication system, and is not limited to including only one NG-RAN device.

[0204] It should be understood that the above Figure 3 or Figure 4The devices or functional nodes included are merely illustrative and do not constitute a limitation on the embodiments of this application. In fact, Figure 3 or Figure 4 It may also include other network elements, devices, or functional nodes that have interactive relationships with the devices or functional nodes shown in the figure, without specific limitations here.

[0205] Optionally, the terminal equipment in this application embodiment may refer to access terminal, user unit, user station, mobile station, mobile station, relay station, remote station, remote terminal, mobile device, user terminal, UE, terminal, wireless communication device, user agent, user device, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication function, computing device or other processing device connected to wireless modem, vehicle-mounted device, wearable device, terminal equipment in future 5G networks, terminal equipment in future evolved PLMNs, or terminal equipment in future vehicle networks, etc. This application embodiment does not limit this.

[0206] By way of example and not limitation, in the embodiments of this application, the terminal may be a mobile phone, tablet computer, computer with wireless transceiver function, virtual reality terminal device, augmented reality terminal device, wireless terminal in industrial control, wireless terminal in autonomous driving, wireless terminal in remote surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc.

[0207] As an example and not a limitation, in this application embodiment, wearable devices can also be called wearable smart devices. This is a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, 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 merely hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction. Broadly defined, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functionality without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific application function and require use with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0208] Furthermore, in this embodiment, the terminal device can also be a terminal device in an IoT system. IoT is an important component of future information technology development, and its main technical feature is connecting objects to networks through communication technologies, thereby realizing an intelligent network of human-machine interconnection and machine-to-machine interconnection. In this embodiment, IoT technology can achieve massive connectivity, deep coverage, and low terminal power consumption through technologies such as narrowband (NB).

[0209] In addition, in the embodiments of this application, the terminal device may also include sensors such as smart printers, train detectors, and gas stations. Its main functions include collecting data (for some terminal devices), receiving control information and downlink data from the access network device, and sending electromagnetic waves to transmit uplink data to the access network device.

[0210] Optionally, the access network device in this application embodiment (including the first access network device or the second access network device mentioned above) can be any kind of communication device with wireless transceiver function used to communicate with terminal devices. This access network device includes, but is not limited to: evolved node B (eNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or TRP in a wireless fidelity (WIFI) system. The access network device can also be a gNB, TRP, or TP in a 5G system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system. Furthermore, the access network device can also be a network node constituting a gNB or TP, such as a BBU, or a distributed unit (DU).

[0211] In some deployments, a gNB may include a centralized unit (CU) and a dedicated unit (DU). Additionally, a gNB may include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU handles non-real-time protocols and services, implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU handles physical layer protocols and real-time services, implementing radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It is understandable that access network equipment can be one or more of the following: CU node, DU node, and AAU node.

[0212] Optionally, in this application embodiment, the access network device (including the first access network device or the second access network device mentioned above) and the terminal device can communicate via licensed spectrum, unlicensed spectrum, or both simultaneously. The access network device and the terminal device can communicate via spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. This application embodiment does not limit the spectrum resources used between the access network device and the terminal device 101.

[0213] Optionally, the terminal device, access network device (including the first access network device or the second access network device mentioned above), or positioning management device in the embodiments of this application can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water; and it can also be deployed on aircraft, balloons, and artificial satellites in the air. The embodiments of this application do not limit the application scenarios of the terminal device, access network device, or positioning management device.

[0214] Optionally, in this embodiment, the terminal device or access network device (including the aforementioned first access network device or second access network device) or location management device includes a hardware layer, an operating system layer running on top of the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as Linux, Unix, Android, iOS, or Windows. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. Furthermore, this embodiment does not specifically limit the structure of the execution entity of the method provided in this embodiment, as long as it can communicate according to the method provided in this embodiment by running a program that records the code of the method provided in this embodiment. For example, the execution entity of the method provided in this embodiment can be the first access network device, the second access network device, or the location management device, or it can be a functional module in the first access network device, the second access network device, or the location management device capable of calling and executing a program.

[0215] In other words, the relevant functions of the first access network device, the second access network device, or the positioning management device in the embodiments of this application can be implemented by one device, or by multiple devices, or by one or more functional modules within one device. This application does not specifically limit these functions. It is understood that the aforementioned functions can be network elements in hardware devices, software functions running on dedicated hardware, a combination of hardware and software, or virtualization functions instantiated on a platform (e.g., a cloud platform).

[0216] For example, the relevant functions of the first access network device, the second access network device, or the location management device in the embodiments of this application can be achieved through... Figure 5 This is achieved through the communication device 500. Figure 5 The diagram shown is a structural schematic of a communication device 500 provided in an embodiment of this application. The communication device 500 includes one or more processors 501, a communication line 502, and at least one communication interface. Figure 5 (This is merely an example illustration, using a communication interface 504 and a processor 501 as examples. Optionally, a memory 503 may also be included.)

[0217] Processor 501 may be a CPU, a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits used to control the execution of programs according to the present application.

[0218] Communication line 502 may include a path for connecting different components.

[0219] The communication interface 504 can be a transceiver module used to communicate with other devices or communication networks, such as Ethernet, RAN, wireless local area networks (WLAN), etc. For example, the transceiver module can be a transceiver or similar device. Optionally, the communication interface 504 can also be a transceiver circuit located within the processor 501, used to implement the processor's signal input and signal output.

[0220] Memory 503 can be a device with storage function. For example, it can be read-only memory (ROM) or other types of static storage devices capable of storing static information and instructions; random access memory (RAM) or other types of dynamic storage devices capable of storing information and instructions; electrically erasable programmable read-only memory (EEPROM); compact disc read-only memory (CD-ROM) or other optical disc storage; optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.); magnetic disk storage media or other magnetic storage devices; or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but not limited to these.

In specific implementations, they may be other names, and this application does not specifically limit them.

[0231] by Figure 1 The power control system shown is applied to a 5G mobile communication system, with the access network equipment being NG-RAN equipment (where the first access network equipment is the first NG-RAN equipment and the second access network equipment is the second NG-RAN equipment) and the positioning management equipment being LMF, as an example. Figure 3 or Figure 4 The connection diagram shown illustrates a power control method provided in an embodiment of this application. Figure 6 As shown, the power control method includes the following step S601:

[0232] S601. The terminal device sends a reference signal. Correspondingly, the NG-RAN devices involved in the terminal device's positioning (including the first NG-RAN device and one or more second NG-RAN devices) receive the reference signal from the terminal device.

[0233] For example, in the embodiments of this application, the reference signal sent by the terminal device may include, but is not limited to, pos-SRS, SRS, demodulation reference signal (DMRS), or phase tracking reference signal (PTRS).

[0234] Furthermore, in the power control method provided in this application embodiment, for any second NG-RAN device participating in terminal device positioning, the following steps S602-S604 are executed:

[0235] S602. After measuring the received reference signal, the second NG-RAN device determines the second power adjustment auxiliary information.

[0236] In this embodiment, the second power control adjustment assistance information may include at least one of the following parameters: a second power control adjustment value, a second power control adjustment direction, and a second measurement result. The second measurement result is the measurement result obtained by the second NG-RAN device measuring the reference signal sent by the terminal device. The second power control adjustment value or the second power control adjustment direction is determined by the second NG-RAN device based on the second measurement result.

[0237] For example, the measurement results in the embodiments of this application (including the first measurement result, the second measurement result, or the third measurement result, etc. below) may include SINR, reference signal receiving power (RSRP), or reference signal receiving quality (RSRQ), etc., which will be uniformly described here and will not be repeated below.

[0238] In the embodiments of this application, the power adjustment direction (including the second power adjustment direction or the first power adjustment direction, third power adjustment direction, or other power adjustment directions described below) is used to characterize the direction in which the current uplink transmit power of the terminal device is recommended to be adjusted. For example, the power adjustment direction can be a "negative direction" or "-" or "reduce power or lower power"; or, the power adjustment direction can be a "positive direction" or "+" or "increase power or increase power"; or, the power adjustment direction can be "no change in direction" or "0".

[0239] In this embodiment, the power adjustment value (including a second power adjustment value, or the first power adjustment value, third power adjustment value, or other power adjustment values ​​described below) is used to characterize the numerical value of the proposed adjustment to the current uplink transmit power of the terminal device. Optionally, the power adjustment value is also used to characterize the direction of the proposed adjustment to the current uplink transmit power of the terminal device. The description of the proposed direction of the current uplink transmit power adjustment for the terminal device can be found in the description of the power adjustment direction, and will not be repeated here.

[0240] It should be understood that when the power adjustment value is distinguished as positive or negative, the power adjustment value is used not only to represent the recommended adjustment amount of the current uplink transmit power of the terminal device, but also to represent the recommended direction of the adjustment. For example, a power adjustment value of -10 can indicate a recommended reduction of 10dB in the current uplink transmit power of the terminal device. Or, a power adjustment value of 10 can indicate a recommended increase of 10dB in the current uplink transmit power of the terminal device.

[0241] It should be understood that when the power adjustment value is used only to characterize the recommended adjustment of the current uplink transmit power of the terminal device, without distinguishing between positive and negative numbers, the power adjustment value and the power adjustment direction can indicate how much the current uplink transmit power of the terminal device should be increased or decreased. For example, when the power adjustment value is 10 and the power adjustment direction is "negative," it can indicate that the current uplink transmit power of the terminal device should be decreased by 10dB. Or, when the second power adjustment value is 10 and the power adjustment direction is "positive," it can indicate that the current uplink transmit power of the terminal device should be increased by 10dB.

[0242] For example, taking a measurement result including SINR as an example, assuming that the SINR in the measurement result is greater than the target SINR, the power adjustment value can be a negative value or the absolute value of that negative value. That is, it can be suggested to reduce the uplink transmit power of the terminal device by one step (the step is equal to the absolute value of the negative value). Assuming that the SINR in the measurement result is less than the target SINR, the power adjustment value can be a positive value. That is, it can be suggested to increase the uplink transmit power of the terminal device by one step (the step is equal to the positive value). Assuming that the SINR in the measurement result is equal to the target SINR, the power adjustment value can be zero. That is, it can be suggested that no adjustment be made to the current uplink transmit power of the terminal device. It should be noted that, in the embodiments of this application, the step size for adjusting the uplink transmit power of the terminal device may be different from the step size for adjusting the uplink transmit power of the terminal device defined in the existing protocol. This will be uniformly explained here and will not be repeated below.

[0243] For example, taking a measurement result including SINR as an example, assuming the SINR in the measurement result is greater than the target SINR, the power adjustment direction can be "negative direction," "-," or "reduce power or lower power," etc., meaning it can be suggested to lower the uplink transmit power of the terminal device. Assuming the SINR in the measurement result is less than the target SINR, the power adjustment direction can be "positive direction," "+," or "increase power or raise power," etc., meaning it can be suggested to increase the uplink transmit power of the terminal device. Assuming the SINR value in the measurement result is equal to the target SINR, the power adjustment direction can be "no change in direction" or "0," meaning it can be suggested that no adjustment be made to the current uplink transmit power of the terminal device.

[0244] Optionally, in addition to the parameters described above, the second power adjustment assistance information in this embodiment may also include at least one of the following parameters: a second reference signal resource set identifier (reference signalresourcesetID), a second reference signal resource identifier (reference signalresourceID), a second reference signal carrier list (reference signalcarrierlist), and a second reference signal transmission timestamp (timestamp of reference signaltransmission). The second reference signal resource set identifier indicates the resource set to which the reference signal corresponding to the second power adjustment assistance information belongs. The second reference signal resource identifier indicates the reference signal corresponding to the second power adjustment assistance information.

[0245] The second reference signal carrier list is used to indicate the carrier list to which the reference signal corresponding to the second power adjustment auxiliary information belongs.

[0246] The second reference signal transmission timestamp is used to indicate the transmission time of the reference signal corresponding to the second power adjustment auxiliary information.

[0247] It should be understood that in the embodiments of this application, the second power adjustment value, the second power adjustment direction, the second measurement result, the second reference signal resource set identifier, the second reference signal resource identifier, the second reference signal carrier list, or the second reference signal transmission timestamp can all be one or more. In other words, in the embodiments of this application, the second power adjustment auxiliary information can be a set of power adjustment auxiliary information or multiple sets of power adjustment auxiliary information. Several combination examples of each set of power adjustment auxiliary information are given below. For example, in the embodiments of this application, each set of power adjustment auxiliary information includes a second power adjustment value and a second reference signal resource set identifier. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes a second power adjustment value, a second power adjustment direction, and a second reference signal resource set identifier. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes a second measurement result and a second reference signal resource set identifier. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes a second power adjustment direction and a second reference signal resource set identifier.

[0248] S603, LMF sends a third message to the second NG-RAN device. Correspondingly, the second NG-RAN device receives the third message from LMF. The third message is used to request power adjustment assistance information from the terminal device.

[0249] S604, the second NG-RAN device sends a fifth message to the LMF. Correspondingly, the LMF receives the fifth message from the second NG-RAN device. The fifth message includes the aforementioned second power adjustment assistance information.

[0250] like Figure 6 As shown in this embodiment, the third message can be NRPPa message 1, and the fifth message can be NRPPa message 2. For example, the third message can be a measurement request, and the fifth message can be a measurement response.

[0251] Optionally, unlike the method of obtaining the second power adjustment assistance information in steps S603-S604, in this embodiment, the second NG-RAN device may proactively send the second power adjustment assistance information to the LMF without request. That is, step S603 can be omitted, and step S604 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S603 is omitted and step S604 is executed, the fifth message is no longer a response message but can be a reporting message, such as a measurement report.

[0252] Furthermore, the power control method provided in this application embodiment also includes the following steps S605-S609:

[0253] S605, the first NG-RAN device sends a first message to the LMF. Correspondingly, the LMF receives the first message from the first NG-RAN device. The first message is used to request power adjustment assistance information from the corresponding terminal device.

[0254] S606, the LMF sends a sixth message to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the sixth message from the LMF. The sixth message includes the aforementioned first power adjustment assistance information. This first power adjustment assistance information is determined by the LMF based on second power adjustment assistance information sent by one or more second NG-RAN devices.

[0255] In this embodiment, the first power adjustment assistance information may include second power adjustment assistance information sent by one or more second NG-RAN devices; or, the first power adjustment assistance information may include part of the second power adjustment assistance information sent by one or more second NG-RAN devices (i.e., the first power adjustment assistance information can be considered as obtained by filtering the second power adjustment assistance information sent by one or more second NG-RAN devices); or, the first power adjustment assistance information is obtained by integrating the second power adjustment assistance information sent by one or more second NG-RAN devices. This embodiment does not specifically limit this.

[0256] For example, if one or more second NG-RAN devices (all second NG-RAN devices involved in terminal device positioning) recommend increasing the uplink transmit power of the terminal device, the LMF can determine the set of power adjustment assistance information corresponding to the maximum adjustment value as the first power adjustment assistance information. If one or more second NG-RAN devices recommend decreasing the uplink transmit power of the terminal device, the LMF can determine the set of power adjustment assistance information corresponding to the adjustment value with the smallest absolute value as the first power adjustment assistance information. If some of the one or more second NG-RAN devices recommend increasing the uplink transmit power of the terminal device and some of the second NG-RAN devices recommend decreasing the uplink transmit power of the terminal device, the LMF needs to determine the set of power adjustment assistance information corresponding to the maximum adjustment value among the increased values ​​as the first power adjustment assistance information.

[0257] It should be noted that, in this embodiment, when the second power adjustment assistance information includes a second reference signal resource set identifier, a second reference signal resource identifier, a second reference signal carrier list, or a second reference signal transmission timestamp, the aforementioned maximum adjustment value (when it is recommended to increase) or the adjustment value with the smallest absolute value (when it is recommended to decrease) can be the maximum adjustment value or the adjustment value with the smallest absolute value under the same second reference signal resource set identifier, the same second reference signal resource identifier, the same second reference signal carrier list, or the same second reference signal transmission timestamp sent by one or more second NG-RAN devices. In other words, the first power adjustment assistance information in this embodiment can include multiple sets of integrated power adjustment assistance information corresponding to different second reference signal resource set identifiers, different second reference signal resource identifiers, different second reference signal carrier lists, or different second reference signal transmission timestamps. Of course, the first power adjustment assistance information in this embodiment can also be a set of power adjustment assistance information determined based on the second power adjustment assistance information sent by one or more second NG-RAN devices, and this embodiment does not specifically limit this.

[0258] As can be seen from the above scheme, in the embodiments of this application, the first power adjustment auxiliary information may include at least one of the following parameters: first power control adjustment value, first power control adjustment direction, and first measurement results.

[0259] The first measurement result is the measurement result determined by the LMF based on the second measurement results sent by one or more second NG-RAN devices. For example, the first measurement result includes the second measurement results sent by one or more second NG-RAN devices; or, the first measurement result includes a portion of the second measurement results sent by one or more second NG-RAN devices, such as the set of measurement results that has the largest deviation from the target SINR (including those lower or higher than the target SINR).

[0260] The first power adjustment value is determined by the LMF based on the second power adjustment value or the second measurement result. For example, assuming the second power adjustment auxiliary information includes the second power adjustment value, the first power adjustment value may include the second power adjustment values ​​sent by one or more second NG-RAN devices; or, the first power adjustment value may include a portion of the second power adjustment values ​​sent by one or more second NG-RAN devices, such as the maximum adjustment value (when a higher adjustment is recommended) or the adjustment value with the smallest absolute value (when a lower adjustment is recommended) in the example above. For example, assuming the second power adjustment auxiliary information includes the second measurement result, the first power adjustment value may include one or more power adjustment values ​​determined based on the second measurement results sent by one or more second NG-RAN devices; or, the first power adjustment value may include the maximum adjustment value (when a higher adjustment is recommended) or the adjustment value with the smallest absolute value (when a lower adjustment is recommended) among the one or more power adjustment values ​​determined based on the second measurement results sent by one or more second NG-RAN devices. The method for determining the power adjustment value based on the measurement result can be referred to the example in step S602, and will not be repeated here.

[0261] The first power adjustment direction is determined by the LMF based on the second power adjustment direction or the second measurement result. For example, assuming the second power adjustment auxiliary information includes a second power adjustment direction, the first power adjustment direction may include the second power adjustment directions sent by one or more second NG-RAN devices; or, the first power adjustment direction may include a portion of the second power adjustment directions sent by one or more second NG-RAN devices, such as if all one or more power adjustment directions are positive, then the first power adjustment direction is positive; or, if all one or more power adjustment directions are negative, then the first power adjustment direction is negative; or, if some of the power adjustment directions are positive and some are negative, then the first power adjustment direction is positive. For example, assuming the second power adjustment auxiliary information includes a second measurement result, the first power adjustment direction may include one or more power adjustment directions determined based on the second measurement results sent by one or more second NG-RAN devices; or, the first power adjustment direction may include a portion of the power adjustment directions determined based on the second measurement results sent by one or more second NG-RAN devices. Related examples can be found in the foregoing content and will not be repeated here. The method for determining the power adjustment direction based on the measurement results can be found in the example in step S602, and will not be repeated here.

[0262] Optionally, in addition to the parameters described above, the first power adjustment assistance information in this embodiment may also include at least one of the following parameters: a first reference signal resource set identifier (reference signalresourcesetID), a first reference signal resource identifier (reference signalresourceID), a first reference signal carrier list (reference signalcarrierlist), and a first reference signal transmission timestamp (timestamp of reference signaltransmission). The first reference signal resource set identifier indicates the resource set to which the reference signal corresponding to the first power adjustment assistance information belongs. The first reference signal resource identifier indicates the reference signal corresponding to the first power adjustment assistance information.

[0263] The first reference signal carrier list is used to indicate the carrier list to which the reference signal corresponding to the first power adjustment auxiliary information belongs.

[0264] The first reference signal transmission timestamp is used to indicate the transmission time of the reference signal corresponding to the first power adjustment auxiliary information.

[0265] It should be understood that in the embodiments of this application, the first reference signal resource set identifier and the second reference signal resource set identifier may be the same, or the first reference signal resource set identifier may be a part of the second reference signal resource set identifier. Similarly, the first reference signal resource identifier and the second reference signal resource identifier may be the same, or the first reference signal resource identifier may be a part of the second reference signal resource identifier. The first reference signal carrier list and the second reference signal carrier list may be the same, or the first reference signal carrier list may be a part of the second reference signal carrier list. The first reference signal transmission timestamp and the second reference signal transmission timestamp may be the same, or the first reference signal transmission timestamp may be a part of the second reference signal transmission timestamp.

[0266] It should be understood that in the embodiments of this application, the first power adjustment value, the first power adjustment direction, the first measurement result, the first reference signal resource set identifier, the first reference signal resource identifier, the first reference signal carrier list, or the first reference signal transmission timestamp can all be one or more. In other words, in the embodiments of this application, the first power adjustment auxiliary information can be a set of power adjustment auxiliary information or multiple sets of power adjustment auxiliary information. Several combination examples of each set of power adjustment auxiliary information are given below. For example, in the embodiments of this application, each set of power adjustment auxiliary information includes a first power adjustment value and a first reference signal resource set identifier. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes a first power adjustment value, a first power adjustment direction, and a first reference signal resource set identifier. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes a first measurement result and a first reference signal resource set identifier. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes a first power adjustment direction and a first reference signal resource set identifier.

[0267] like Figure 6 As shown in the embodiment of this application, the first message can be NRPPa message 3, and the sixth message can be NRPPa message 4.

[0268] In one possible implementation, the first and sixth messages can be existing NRPPa messages. For example, the first message can be a positioning information request; correspondingly, the sixth message can be a positioning information response. Alternatively, for example, the first message can be a positioning activation request; correspondingly, the sixth message can be a positioning activation response.

[0269] In another possible implementation, the first and sixth messages can be newly defined NRPPa messages. For example, the first message can be a power adjustment request; correspondingly, the sixth message can be a power adjustment response.

[0270] Optionally, unlike the method of obtaining the first power adjustment assistance information in steps S605-S606, in this embodiment, the LMF may also proactively send the first power adjustment assistance information to the first NG-RAN device without request. That is, step S605 can be omitted, and step S606 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S605 is omitted and step S606 is executed, the sixth message is no longer a response message but can be a reporting message, such as a power control adjustment report.

[0271] S607. The terminal device sends a medium access control (MAC) control element (CE) to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the MAC CE from the terminal device. This MAC CE includes a PHR.

[0272] For example, the PHR in the embodiments of this application can be a type 3 PHR.

[0273] S608, the first NG-RAN device determines the power adjustment information based on the first power adjustment information.

[0274] In this embodiment, the first NG-RAN device determines power adjustment information based on the first power adjustment information, including: the first NG-RAN device determines power adjustment information based on a third measurement result and / or the PHR sent by the terminal device, and the first power adjustment auxiliary information. The third measurement result is the measurement result obtained by the first NG-RAN device measuring the reference signal sent by the terminal device.

[0275] In this embodiment of the application, when the first power adjustment assistance information includes the second power adjustment assistance information sent by one or more second NG-RAN devices, the first NG-RAN device determines the power adjustment information in a manner similar to that of the LMF in determining the first power adjustment information based on the third measurement result and / or the PHR sent by the terminal device and the first power adjustment assistance information. The difference is that, for example, the first NG-RAN device also needs to consider the third measurement result and / or the PHR sent by the terminal device when determining the power adjustment information, which will not be elaborated here.

[0276] In this embodiment, when the first power adjustment assistance information includes part of the second power adjustment assistance information sent by one or more second NG-RAN devices, or when the first power adjustment assistance information is obtained by integrating the second power adjustment assistance information sent by one or more second NG-RAN devices, the method by which the first NG-RAN device determines the power adjustment information based on the third measurement result and / or the PHR sent by the terminal device, and the first power adjustment assistance information, can refer to the method where the second power adjustment assistance information includes the second measurement result, and the LMF needs to combine multiple second power adjustment assistance information to determine the first power adjustment assistance information. The difference is that, for example, the first NG-RAN device also needs to consider the PHR sent by the terminal device when determining the power adjustment information, which will not be elaborated here.

[0277] The power adjustment information in this embodiment includes a power adjustment value and / or a power adjustment direction. Optionally, the power adjustment information in this embodiment may further include one or more of the following: a reference signal resource set identifier, a reference signal resource identifier, a reference signal carrier list, or a reference signal transmission timestamp. The reference signal resource set identifier indicates the resource set to which the reference signal corresponding to the power adjustment information belongs. The reference signal resource identifier indicates the reference signal corresponding to the power adjustment information. The reference signal carrier list indicates the carrier list to which the reference signal corresponding to the power adjustment information belongs. The reference signal transmission timestamp indicates the transmission time of the reference signal corresponding to the power adjustment information.

[0278] It should be understood that in the embodiments of this application, the power adjustment value, power adjustment direction, reference signal resource set identifier, reference signal resource identifier, reference signal carrier list, or reference signal transmission timestamp can all be one or more. In other words, in the embodiments of this application, the power adjustment information can be a set of power adjustment information or multiple sets of power adjustment information. Several combination examples of each set of power adjustment information are given below. For example, in the embodiments of this application, each set of power adjustment information includes a power adjustment value and a reference signal resource set identifier. Alternatively, for example, in the embodiments of this application, each set of power adjustment information includes a power adjustment value, a power adjustment direction, and a reference signal resource set identifier. Alternatively, for example, in the embodiments of this application, each set of power adjustment information includes a power adjustment direction and a reference signal resource set identifier.

[0279] S609, the first NG-RAN device sends a TPC command to the terminal device. Correspondingly, the terminal device receives the TPC command from the first NG-RAN device. This TPC command includes the power adjustment value determined by the first NG-RAN device.

[0280] In this embodiment, after the terminal device obtains the power adjustment value determined by the first NG-RAN device, it can adjust the uplink transmit power of the terminal device according to the power adjustment value. Specific adjustments can be found in existing methods and will not be elaborated here. Furthermore, the terminal device can send a reference signal according to the adjusted uplink transmit power to complete the positioning process. General positioning procedures can be found in existing technologies and will not be elaborated here.

[0281] In the localization problem, the reference signal transmitted by the terminal device is useful to all NG-RAN devices participating in the localization process; that is, all NG-RAN devices participating in the localization process need to measure the reference signal transmitted by the terminal device. In the solution provided in this application, the power adjustment information determined by the first NG-RAN device not only considers the measurement results obtained by the first NG-RAN device from measuring the reference signal transmitted by the terminal device, but also considers the first power adjustment auxiliary information transmitted by the LMF. This first power adjustment auxiliary information is determined by the LMF based on the second power adjustment auxiliary information transmitted by one or more second NG-RAN devices. In other words, in this application embodiment, the power adjustment information used by the terminal device to adjust its uplink transmit power is determined based on the second power adjustment auxiliary information provided by the neighboring NG-RAN devices of the terminal device participating in the localization process and the reference signal measurement results provided by the serving NG-RAN device of the terminal device. Therefore, it meets the requirements of the localization problem and can realize uplink power control in the localization process.

[0282] The operation of the first NG-RAN device, the second NG-RAN device, or the LMF in steps S601 to S609 can be performed by... Figure 5 The processor 501 in the communication device 500 shown executes the application code stored in the memory 503.

[0285] Furthermore, the power control method provided in this application embodiment also includes the following steps S705-S707:

[0286] S705, the terminal device sends a MAC CE to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the MAC CE from the terminal device. This MAC CE includes the PHR.

[0287] For example, the PHR in the embodiments of this application can be a type 3 PHR.

[0288] S706, LMF sends a fourth message to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the fourth message from LMF. The fourth message is used to request power adjustment assistance information from the terminal device.

[0289] S707, the first NG-RAN device sends a seventh message to the LMF. Correspondingly, the LMF receives the seventh message from the first NG-RAN device. The seventh message includes third power adjustment assistance information.

[0290] In this embodiment, the third power adjustment auxiliary information includes at least one of the following parameters: a third power adjustment value, a third power adjustment direction, a third measurement result, and a PHR sent by the terminal device; wherein, the third measurement result is the measurement result obtained by the first NG-RAN device measuring the reference signal sent by the terminal device. The third power adjustment value or the third power adjustment direction is determined by the first NG-RAN device based on the third measurement result.

[0291] Optionally, in this embodiment, the third power adjustment assistance information further includes at least one of the following parameters: a third reference signal resource set identifier, a third reference signal resource identifier, a third reference signal carrier list, and a third reference signal transmission timestamp. The descriptions of the parameters in the third power adjustment assistance information can be found in the descriptions of the relevant parameters in the second power adjustment assistance information, and will not be repeated here.

In other words, in the embodiments of this application, the third power adjustment auxiliary information can be a set of power adjustment auxiliary information or multiple sets of power adjustment auxiliary information. Several combination examples of each set of power adjustment auxiliary information are given below. For example, in the embodiments of this application, each set of power adjustment auxiliary information includes the PHR, third power adjustment value, and third reference signal resource set identifier sent by the terminal device. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes the PHR, third power adjustment value, third power adjustment direction, and third reference signal resource set identifier sent by the terminal device. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes the PHR, third measurement result, and third reference signal resource set identifier sent by the terminal device. Or, for example, in the embodiments of this application, each set of power adjustment auxiliary information includes the PHR, third power adjustment direction, and third reference signal resource set identifier sent by the terminal device.

[0293] like Figure 7 As shown in this embodiment, the fourth message can be NRPPa message 5, and the seventh message can be NRPPa message 6. For example, the fourth message can be a measurement request, and the seventh message can be a measurement response.

[0294] Optionally, unlike the method of obtaining the third power adjustment assistance information in steps S706-S707, in this embodiment, the first NG-RAN device may proactively send the third power adjustment assistance information to the LMF without request. That is, step S706 can be omitted, and step S707 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S706 is omitted and step S707 is executed, the seventh message is no longer a response message but can be a reporting message, such as a measurement report.

[0295] Furthermore, in one possible implementation, the power control method provided in this application embodiment further includes the following steps S708-S711:

[0296] S708, the first NG-RAN device sends a ninth message to the LMF. Correspondingly, the LMF receives the ninth message from the first NG-RAN device. The ninth message is used to request power adjustment information from the terminal device.

[0297] S709 and LMF determine power adjustment information based on the second power adjustment assistance information sent by one or more second NG-RAN devices and the third power adjustment assistance information sent by the first NG-RAN device. A description of the power adjustment information can be found in [reference needed]. Figure 6 The embodiments shown will not be described in detail here.

[0298] In this embodiment, the LMF determines the power adjustment information in a manner consistent with the second power adjustment assistance information sent by one or more second NG-RAN devices and the third power adjustment assistance information sent by the first NG-RAN device. Figure 6 In the embodiments shown, when the first power adjustment assistance information includes second power adjustment assistance information sent by one or more second NG-RAN devices, the way the first NG-RAN device determines the power adjustment information based on the first power adjustment information is similar and will not be described again here.

[0299] For example, if all NG-RAN devices participating in the terminal device location (including a first NG-RAN device and one or more second NG-RAN devices) recommend increasing the uplink transmit power of the terminal device, the LMF can use the smaller of the maximum adjustment value and the PHR reported by the terminal device as the final power adjustment value. If all NG-RAN devices participating in the terminal device location (including a first NG-RAN device and one or more second NG-RAN devices) recommend decreasing the uplink transmit power of the terminal device, the LMF can use the adjustment value with the smallest absolute value as the final power adjustment value. If some NG-RAN devices participating in the terminal device location (including a first NG-RAN device and one or more second NG-RAN devices) recommend increasing the uplink transmit power of the terminal device, and some NG-RAN devices recommend decreasing the uplink transmit power of the terminal device, the LMF needs to use the smaller of the maximum adjustment value and the PHR reported by the terminal device as the final power adjustment value.

[0300] S710, LMF sends a tenth message to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the tenth message from LMF. The tenth message includes the power adjustment information from step S709.

[0301] like Figure 7 As shown in the embodiment of this application, the ninth message can be NRPPa message 7, and the tenth message can be NRPPa message 8.

For example, the ninth message can be a positioning information request; correspondingly, the tenth message can be a positioning information response. Alternatively, for example, the ninth message can be a positioning activation request; correspondingly, the tenth message can be a positioning activation response.

[0303] In another possible implementation, the ninth and tenth messages can be newly defined NRPPa messages. For example, the ninth message can be a power adjustment request; correspondingly, the tenth message can be a power adjustment response.

[0304] Optionally, unlike the method of obtaining power adjustment information in steps S708-S710, in this embodiment, the LMF may proactively send power adjustment information to the first NG-RAN device without request. That is, step S708 can be omitted, and steps S709-S710 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S708 is omitted and steps S709-S710 are executed, the tenth message is no longer a response message but can be a reporting message, such as a power control adjustment report.

[0305] S711, the first NG-RAN device sends a TPC command to the terminal device. Correspondingly, the terminal device receives the TPC command from the first NG-RAN device. This TPC command includes the power adjustment value determined by the first NG-RAN device.

[0306] Alternatively, after step S707, in another possible implementation, the power control method provided in this application embodiment further includes the following steps S712-S714:

[0307] S712, the terminal device sends an eleventh message to the LMF. Correspondingly, the LMF receives the eleventh message from the terminal device. The eleventh message is used to request the corresponding power adjustment information from the terminal device.

[0308] S713, LMF determines the power adjustment information based on the second power adjustment assistance information sent by one or more second NG-RAN devices and the third power adjustment assistance information sent by the first NG-RAN device.

[0309] The specific implementation of step S713 can be referred to the specific implementation of step S709 above, and will not be repeated here.

[0310] S714, the LMF sends a twelfth message to the terminal device. Correspondingly, the terminal device receives the twelfth message from the LMF. The twelfth message includes the power adjustment information from step S713.

[0311] like Figure 7 As shown in the embodiment of this application, the eleventh message can be LTE positioning protocol (LPP) message 1, and the twelfth message can be LPP message 2.

[0312] In one possible implementation, the eleventh and twelfth messages can be existing LPP messages. For example, the eleventh message can be a request assistance data message; correspondingly, the twelfth message can be a provide assistance data message.

[0313] In another possible implementation, the eleventh and twelfth messages can be newly defined LPP messages. For example, the eleventh message can be a request power control information message; correspondingly, the twelfth message can be a provide power control information message.

[0314] Optionally, unlike the method of obtaining power adjustment information in steps S712-S714, in this embodiment, the LMF may proactively send power adjustment information to the terminal device without request. That is, step S712 may be omitted, and steps S713-S714 may be executed instead. This embodiment does not specifically limit this. It should be understood that when step S712 is omitted and steps S713-S714 are executed, the twelfth message is no longer a response message but can be a reporting message, such as a power control adjustment report.

[0315] In this embodiment, after the terminal device obtains the power adjustment value determined by the first NG-RAN device, it can adjust the uplink transmit power of the terminal device according to the power adjustment value. Specific adjustments can be found in existing methods and will not be elaborated here. Furthermore, the terminal device can send a reference signal according to the adjusted uplink transmit power to complete the positioning process. General positioning procedures can be found in existing technologies and will not be elaborated here.

[0316] In the positioning problem, the reference signal transmitted by the terminal device is useful to all NG-RAN devices participating in the positioning process; that is, all NG-RAN devices participating in the positioning process need to measure the reference signal transmitted by the terminal device. In the solution provided in this application, the power adjustment information used by the terminal device to adjust its uplink transmit power is determined based on the second power adjustment auxiliary information provided by the neighboring NG-RAN devices of the terminal device participating in the positioning process and the third power adjustment auxiliary information provided by the serving NG-RAN device of the terminal device. Therefore, it meets the requirements of the positioning problem and can realize uplink power control in the positioning process.

[0317] The operation of the first NG-RAN device, the second NG-RAN device, or the LMF in steps S701 to S714 can be performed by... Figure 5 The processor 501 in the communication device 500 shown executes the application code stored in the memory 503.

[0318] by Figure 1 The power control system shown is applied to a 5G mobile communication system, with the access network equipment being NG-RAN equipment (where the first access network equipment is the first NG-RAN equipment and the second access network equipment is the second NG-RAN equipment) and the positioning management equipment being LMF, as an example.

[0319] S801-S804, same Figure 6 Steps S601-S604 in the illustrated embodiment are described in detail below. Figure 6 The embodiments shown will not be described in detail here.

[0320] Furthermore, the power control method provided in this application embodiment also includes the following steps S805-S811:

[0321] S805, the terminal device sends a MAC CE to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the MAC CE from the terminal device. This MAC CE includes the PHR.

[0322] For example, the PHR in the embodiments of this application can be a type 3 PHR.

[0323] S806, LMF sends a fourth message to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the fourth message from LMF. The fourth message is used to request power adjustment assistance information from the terminal device.

[0324] S807, the first NG-RAN device sends a seventh message to the LMF. Correspondingly, the LMF receives the seventh message from the first NG-RAN device. The seventh message includes third power adjustment assistance information.

[0325] The relevant description of the third power adjustment auxiliary information can be found in the following reference. Figure 7 The embodiments shown will not be described again here. It should be noted that, in the embodiments of this application, the third power adjustment assistance information may not include the PHR sent by the terminal device.

[0326] like Figure 8 As shown in this embodiment, the fourth message can be NRPPa message 5, and the seventh message can be NRPPa message 6. For example, the fourth message can be a measurement request, and the seventh message can be a measurement response.

[0327] Optionally, unlike the method of obtaining the third power adjustment assistance information in steps S806-S807, in this embodiment, the first NG-RAN device may proactively send the third power adjustment assistance information to the LMF without request. That is, step S806 can be omitted, and step S807 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S806 is omitted and step S807 is executed, the seventh message is no longer a response message but can be a reporting message, such as a measurement report.

[0328] S808, the first NG-RAN device sends a first message to the LMF. Correspondingly, the LMF receives the first message from the first NG-RAN device. The first message is used to request power adjustment assistance information from the terminal device.

[0329] S809, the LMF sends a sixth message to the first NG-RAN device. Correspondingly, the LMF receives the sixth message from the first NG-RAN device. The sixth message includes first power adjustment assistance information. This first power adjustment assistance information is determined by the LMF based on second power adjustment assistance information sent by one or more second NG-RAN devices and third power adjustment assistance information sent by the first NG-RAN device.

[0330] In the embodiments of this application, the first power adjustment assistance information may include second power adjustment assistance information sent by one or more second NG-RAN devices and third power adjustment assistance information sent by the first NG-RAN device; or, the first power adjustment assistance information may include part of the second power adjustment assistance information sent by one or more second NG-RAN devices and the third power adjustment assistance information sent by the first NG-RAN device (that is, it can be considered that the first power adjustment assistance information is obtained by filtering the second power adjustment assistance information sent by one or more second NG-RAN devices and the third power adjustment assistance information sent by the first NG-RAN device); or, the first power adjustment assistance information is obtained by integrating the second power adjustment assistance information sent by one or more second NG-RAN devices and the third power adjustment assistance information sent by the first NG-RAN device. The embodiments of this application do not specifically limit this.

[0331] The specific implementation of steps S808-S809 is as follows: Figure 6 Steps S605-S606 in the illustrated embodiment are similar.

[0332] The difference lies in that, in the embodiments of this application, the first power adjustment assistance information determined by the LMF also takes into account the third power adjustment assistance information sent by the first NG-RAN device, which will not be elaborated here.

[0333] For example, if all NG-RAN devices participating in the terminal device positioning (including a first NG-RAN device and one or more second NG-RAN devices) recommend increasing the uplink transmit power of the terminal device, the LMF can determine a set of power adjustment assistance information corresponding to the maximum adjustment value as the first power adjustment assistance information. If all NG-RAN devices participating in the terminal device positioning (including a first NG-RAN device and one or more second NG-RAN devices) recommend decreasing the uplink transmit power of the terminal device, the LMF can determine a set of power adjustment assistance information corresponding to the adjustment value with the smallest absolute value as the first power adjustment assistance information. If some NG-RAN devices participating in the terminal device positioning (including a first NG-RAN device and one or more second NG-RAN devices) recommend increasing the uplink transmit power of the terminal device, and some NG-RAN devices recommend decreasing the uplink transmit power of the terminal device, the LMF needs to determine a set of power adjustment assistance information corresponding to the maximum adjustment value among the increased values ​​as the first power adjustment assistance information.

[0334] Optionally, unlike the method of obtaining the first power adjustment assistance information in steps S808-S809, in this embodiment, the LMF may also proactively send the first power adjustment assistance information to the first NG-RAN device without request. That is, step S808 can be omitted, and step S809 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S808 is omitted and step S809 is executed instead, the sixth message mentioned above is no longer a response message, but can be a reporting message, such as a power control adjustment report.

[0335] S810 and the first NG-RAN device determine the power adjustment information based on the first power adjustment information.

[0336] In this embodiment of the application, the first NG-RAN device determines the power adjustment information based on the first power adjustment information, including: the first NG-RAN device determines the power adjustment information based on the PHR sent by the terminal device and the first power adjustment auxiliary information.

[0337] For example, if the first power adjustment assistance information suggests increasing the uplink transmit power of the terminal device, the LMF can use the smaller of the power adjustment value suggested by the first power adjustment assistance information and the PHR reported by the terminal device as the final power adjustment value. Alternatively, if the first power adjustment assistance information suggests decreasing the uplink transmit power of the terminal device, the LMF can use the power adjustment value suggested by the first power adjustment assistance information as the final power adjustment value.

[0338] S811, the first NG-RAN device sends a TPC command to the terminal device. Correspondingly, the terminal device receives the TPC command from the first NG-RAN device. This TPC command includes the power adjustment value determined by the first NG-RAN device.

[0339] In this embodiment, after the terminal device obtains the power adjustment value determined by the first NG-RAN device, it can adjust the uplink transmit power of the terminal device according to the power adjustment value. Specific adjustments can be found in existing methods and will not be elaborated here. Furthermore, the terminal device can send a reference signal according to the adjusted uplink transmit power to complete the positioning process. General positioning procedures can be found in existing technologies and will not be elaborated here.

[0340] In the localization problem, the reference signal transmitted by the terminal device is useful to all NG-RAN devices participating in the localization process; that is, all NG-RAN devices participating in the localization process need to measure the reference signal transmitted by the terminal device. In the solution provided in this application, the power adjustment information determined by the first NG-RAN device takes into account the first power adjustment auxiliary information transmitted by the LMF. The first power adjustment auxiliary information is determined by the LMF based on the second power adjustment auxiliary information transmitted by one or more second NG-RAN devices and the third power adjustment auxiliary information transmitted by the first NG-RAN device. In other words, in this application embodiment, the power adjustment information used by the terminal device to adjust its uplink transmit power is determined based on the second power adjustment auxiliary information provided by the neighboring NG-RAN devices of the terminal device participating in the localization process and the third power adjustment auxiliary information provided by the serving NG-RAN device of the terminal device. Therefore, it meets the requirements of the localization problem and can realize uplink power control in the localization process.

[0341] The operation of the first NG-RAN device, the second NG-RAN device, or the LMF in steps S801 to S811 can be performed by... Figure 5 The processor 501 in the communication device 500 shown executes the application code stored in the memory 503.

[0342] by Figure 2 The power control system shown is applied to a 5G mobile communication system, taking NG-RAN equipment (where the first access network equipment is the first NG-RAN equipment and the second access network equipment is the second NG-RAN equipment) as an example. Figure 3 or Figure 4 The connection diagram shown illustrates a power control method provided in an embodiment of this application. Figure 9 As shown, the power control method includes the following step S901:

[0343] S901, same Figure 6 Step S601 in the illustrated embodiment is described in detail below. Figure 6 The embodiments shown will not be described in detail here.

[0344] Furthermore, in the power control method provided in this application embodiment, for any second NG-RAN device participating in terminal device positioning, the following steps S902-S904 are executed:

[0345] S902. After measuring the received reference signal, the second NG-RAN device determines the second power adjustment auxiliary information.

[0346] For a detailed implementation of step S902, please refer to [link / reference]. Figure 6 Step S602 in the illustrated embodiment will not be repeated here.

[0347] S903, the first NG-RAN device sends a second message to the second NG-RAN device. Correspondingly, the second NG-RAN device receives the second message from the first NG-RAN device. The second message is used to request power adjustment assistance information corresponding to the terminal device.

[0348] S904, the second NG-RAN device sends an eighth message to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the eighth message from the second NG-RAN device. The eighth message includes the aforementioned second power adjustment assistance information.

[0349] like Figure 8 As shown, in this embodiment, the second message can be an Xn request message, and the eighth message can be an Xn response message. That is, in this embodiment, the first NG-RAN device and the second NG-RAN device can communicate directly through the Xn interface.

[0350] Optionally, unlike the method of obtaining the second power adjustment assistance information in steps S903-S904, in this embodiment, the second NG-RAN device may proactively send the second power adjustment assistance information to the first NG-RAN device without request. That is, step S903 can be omitted, and step S904 can be executed instead. This embodiment does not specifically limit this. It should be understood that when step S903 is omitted and step S904 is executed, the eighth message is no longer a response message but can be a reporting message, such as a power control adjustment report.

[0351] Furthermore, the power control method provided in this application embodiment also includes the following steps S905-S907:

[0352] S905, the terminal device sends a MAC CE to the first NG-RAN device. Correspondingly, the first NG-RAN device receives the MAC CE from the terminal device. This MAC CE includes the PHR.

[0353] For example, the PHR in the embodiments of this application can be a type 3 PHR.

[0354] S906. The first NG-RAN device determines power adjustment information based on the second power adjustment assistance information sent by one or more second NG-RAN devices, the third measurement result, and / or the PHR sent by the terminal device. The third measurement result is the measurement result obtained by the first NG-RAN device measuring the reference signal sent by the terminal device.

[0355] In this embodiment, the first NG-RAN device determines the power adjustment information in a manner consistent with the second power adjustment assistance information sent by one or more second NG-RAN devices, the third measurement result, and / or the PHR sent by the terminal device. Figure 7 The method by which the LMF determines power adjustment information is the same in the embodiments shown, and will not be repeated here.

[0356] S907, the first NG-RAN device sends a TPC command to the terminal device. Correspondingly, the terminal device receives the TPC command from the first NG-RAN device. This TPC command includes the power adjustment value determined by the first NG-RAN device.

[0357] In this embodiment, after the terminal device obtains the power adjustment value determined by the first NG-RAN device, it can adjust the uplink transmit power of the terminal device according to the power adjustment value. Specific adjustments can be found in existing methods and will not be elaborated here. Furthermore, the terminal device can send a reference signal according to the adjusted uplink transmit power to complete the positioning process. General positioning procedures can be found in existing technologies and will not be elaborated here.

[0358] In the positioning problem, the reference signal transmitted by the terminal device is useful to all NG-RAN devices participating in the positioning process; that is, all NG-RAN devices participating in the positioning process need to measure the reference signal transmitted by the terminal device. In the solution provided in this application, the power adjustment information used by the terminal device to adjust its uplink transmit power is determined based on the second power adjustment auxiliary information provided by the neighboring NG-RAN devices of the terminal device participating in the positioning process and the reference signal measurement results provided by the serving NG-RAN device of the terminal device. Therefore, it meets the requirements of the positioning problem and can realize uplink power control in the positioning process.

[0359] The operation of the first NG-RAN device or the second NG-RAN device in steps S901 to S907 can be performed by... Figure 5 The processor 501 in the communication device 500 shown executes the application code stored in the memory 503.

[0360] Optionally, in the above as follows Figure 6 , Figure 8 or Figure 9 In the power control method shown, the first NG-RAN device can also determine, based on its configuration, whether to adjust the uplink transmit power of the terminal device. When the first NG-RAN device determines that the uplink transmit power of the terminal device should be adjusted, the first NG-RAN device performs the step of determining power adjustment information. Similarly, in the above-described... Figure 7 In the power control method shown, the LMF can also determine whether to adjust the uplink transmit power of the terminal device based on the configuration. When the LMF determines that the uplink transmit power of the terminal device should be adjusted, the LMF executes the step of determining power adjustment information. This avoids the signaling consumption and device power consumption caused by frequently adjusting the uplink transmit power of the terminal device when it is not necessary.

[0361] In one possible implementation, a dedicated timer, Timer_PA, can be defined. Its start condition includes the termination of the previous TPC command; its stop condition includes receiving relevant power adjustment assistance information from all second NG-RAN devices involved in terminal device positioning. Figure 9 Taking the illustrated embodiment as an example, assuming the number of all second NG-RAN devices participating in the terminal device positioning is M, the second power adjustment assistance information sent by the second NG-RAN devices to the first NG-RAN devices includes a second reference signal transmission timestamp. As described above, the second reference signal transmission timestamp is used to indicate the transmission time of the reference signal corresponding to the second power adjustment assistance information. Furthermore, after the timer_PA expires, if the first NG-RAN device receives more than N (N≤M) second power adjustment assistance information messages sent by the second NG-RAN devices, it determines to adjust the uplink transmit power of the terminal device; otherwise, the first NG-RAN device determines that it does not need to adjust the uplink transmit power of the terminal device.

[0362] Optionally, in the above as follows Figure 6 , Figure 8 or Figure 9In the power control method shown, the first NG-RAN device can also determine the frequency for adjusting the uplink transmit power of the terminal device based on either the second power adjustment auxiliary information including a second reference signal transmission timestamp or the first power adjustment auxiliary information including a first reference signal transmission timestamp. For example, the first NG-RAN device can determine which timestamps correspond to the power adjustment auxiliary information to use to determine the power adjustment information for uplink transmit power adjustment, and then send the power adjustment information to the terminal device, which is used by the terminal device to adjust the uplink transmit power. Similarly, in the above-described... Figure 7 In the power control method shown, the LMF can also determine the frequency for adjusting the uplink transmit power of the terminal device based on the second power adjustment auxiliary information including a second reference signal transmission timestamp or the third power adjustment auxiliary information including a third reference signal transmission timestamp. For example, the LMF can determine which timestamps correspond to the power adjustment auxiliary information to determine the power adjustment information used for uplink transmit power adjustment, and then the LMF sends the power adjustment information to the terminal device, or the LMF sends the power adjustment information to the terminal device through the first MG-RAN device. This power adjustment information is used by the terminal device to adjust the uplink transmit power.

[0363] It should be understood and referenced.

Of course, if there is a direct interface between the LMF and the NG-RAN devices, the LMF and the NG-RAN devices can also communicate directly; this application does not specifically limit this.
