Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202110932837.X, filed with the State Intellectual Property Office of China on August 13, 2021, entitled "Communication Processing Method and Communication Processing Device," which is incorporated herein by reference in its entirety.

[0002] The present application relates to the field of communication technology, and in particular to a communication processing method and a communication processing device. [Background technology]

[0003] With the development of indoor positioning, various positioning terminals are widely used in industrial factories, indoor shopping malls, logistics centers, and the like. In indoor positioning, the battery life of most positioning terminals is short. Therefore, low-power positioning is a hot topic in current research. Low-power positioning reduces the power consumption overhead of positioning terminals and improves the battery life of positioning terminal devices.

[0004] Currently, a discontinuous reception (DRX) mode is used to implement low-power positioning. During a DRX cycle, a terminal device periodically wakes up from a deep sleep mode and enters a microsleep mode based on configuration information of a sounding reference signal (SRS). The terminal device first implements downlink time-frequency tracking by using a tracking reference signal (TRS). Next, the terminal device transmits the SRS to an access network device at the time the SRS is transmitted, and the access network device measures the SRS to determine the location of the terminal device, thereby implementing positioning of the terminal device.

[0005] It can be seen that after entering the microsleep mode, the terminal device first needs to implement downlink time-frequency tracking by using the TRS, and then wait for the transmission of the SRS, thereby implementing the positioning of the terminal device. As a result, the power consumption of the terminal device is high. Therefore, how to reduce the power consumption of the terminal device is a problem worth considering. Summary of the Invention

[0006] The embodiments of the present application provide a communication processing method and a communication processing device for reducing the power consumption overhead of a terminal device, thereby improving the battery life of the terminal device.

[0007] A first aspect of the present application provides a communication processing method, including:

[0008] An access network device determines configuration information of an SRS for a terminal device. The access network device determines configuration information of a TRS for the terminal device. The configuration information of the TRS is used to configure one or more first TRS resources, and one first TRS resource is between two adjacent first SRS resources in the SRS resources configured based on the configuration information of the SRS.

[0009] In the above technical solution, one first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. The terminal device switches from deep sleep mode to micro sleep mode, and the terminal device implements time-frequency tracking by using the TRS received on the first TRS resource. The terminal device maintains the micro sleep mode. The terminal device may transmit an SRS on the first SRS resource after the first TRS resource to implement positioning of the terminal device. After transmitting the SRS, the terminal device may enter deep sleep mode. One first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device may transmit the SRS within a short period of time. This reduces the time the terminal device spends maintaining the micro sleep mode, prevents the terminal device from wasting unnecessary power, and thereby reduces the power consumption overhead of the terminal device. In this way, the battery life of the terminal device is improved.

[0010] In a possible implementation, one first TRS resource exists before the first first SRS resource configured based on the configuration information of the SRS.

[0011] In the above implementation, at least one first TRS resource exists before the initial first SRS, so that the terminal device performs downlink time-frequency tracking. In this way, the technical solution of the present application can be applied to several more scenarios. For example, before the first SRS resource, the terminal device is in deep sleep mode. The terminal device needs to switch from deep sleep mode to micro-sleep mode and transmit the SRS held in the first SRS resource. In this case, before the first SRS resource, the terminal device needs to perform downlink time-frequency tracking. Therefore, one first TRS resource can be configured before the initial first SRS resource, so that the terminal device performs downlink time-frequency tracking.

[0012] In another possible implementation, the method further includes the access network device sending the configuration information of the SRS and the configuration information of the TRS to the terminal device.

[0013] In the above implementation, the access network device sends SRS configuration information and TRS configuration information to the terminal device, so that the terminal device receives TRS based on the TRS configuration information and sends SRS based on the SRS configuration information.

[0014] In another possible implementation, the cycle of the first SRS resource is a positive integer multiple of the cycle of the first TRS resource.

[0015] In this implementation, the cycle of the first SRS resource is a positive integer multiple of the cycle of the first TRS resource, ensuring that one first TRS resource exists between two adjacent first SRSs, so that the terminal device performs downlink time-frequency synchronization. In this way, the terminal device can transmit an SRS on the first SRS resource and enter deep sleep mode. In this way, the time spent by the terminal device in microsleep mode is reduced, reducing the power consumption of the terminal device and thereby implementing low-power positioning.

[0016] In another possible implementation, at least one first SRS resource of the multiple first SRS resources configured based on the SRS configuration information is located in an uplink / downlink switch slot, and one first TRS resource is located in the uplink / downlink switch slot in which the first SRS resource is located; at least one first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in the Nth downlink slot before the uplink slot in which the first SRS resource is located, where N is a positive integer; at least one first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in the Nth uplink / downlink switch slot before the uplink slot in which the first SRS resource is located; or at least one first SRS resource of the multiple first SRS resources is located in an uplink / downlink switch slot, and one first TRS resource is located in the Nth downlink slot before the uplink / downlink switch slot in which the first SRS resource is located.

[0017] This possible implementation shows examples of multiple possible positional relationships between the first SRS resource and the first TRS resource. In this way, after the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device can transmit an SRS within a short time and enter a deep sleep state. In this way, the time spent by the terminal device in microsleep mode is reduced, reducing the power consumption of the terminal device and thereby improving the battery life of the terminal device.

[0018] In another possible implementation, the method further includes: the access network device determining that the type of the terminal device is a low-power high-accuracy positioning (LPHAP) terminal device.

[0019] In the above implementation, the terminal device is an LPHAP terminal device and has a requirement for low-power positioning or a long battery life. Therefore, for an LPHAP terminal device, the access network device determines SRS configuration information and TRS configuration information for the terminal device. One first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. Thus, after implementing time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device can transmit an SRS within a short time. This reduces the time the terminal device spends maintaining a microsleep mode, prevents the terminal device from wasting unnecessary power, and thereby reduces the power consumption overhead of the terminal device. Thus, the battery life of the terminal device is improved.

[0020] In another possible implementation, the access network device determining that the type of the terminal device is an LPHAP terminal device includes:

[0021] The access network device receives capability information of the terminal device, where the capability information includes information about the terminal device that is a type of LPHAP terminal device.

[0022] It can be seen that the above shows an example of a possible implementation in which an access network device determines that a terminal device is an LPHAP terminal device. The terminal device can indicate to the access network device that the type of the terminal device is an LPHAP terminal device based on the capability information, and does not need to indicate to the access network device that the type of the terminal device is an LPHAP terminal device by defining a new message. This improves the applicability of the solution.

[0023] In another possible implementation, the access network device determining that the type of the terminal device is an LPHAP terminal device includes:

[0024] The access network device receives a preamble sequence from the terminal device, where the preamble sequence is used by the terminal device to initiate random access to the access network device. Based on the preamble sequence, the access network device identifies the type of the terminal device as an LPHAP terminal device.

[0025] The above implementation shows another implementation example in which the access network device determines that the terminal device is an LPHAP terminal device. The access network device determines that the terminal device is an LPHAP terminal device based on the preamble sequence used by the terminal device to initiate random access. There is no need to redefine a new message to send indication information.

[0026] In another possible implementation, the access network device determining that the type of the terminal device is an LPHAP terminal device includes:

[0027] The access network device receives a radio resource control (RRC) request message from the terminal device, where the RRC request message includes information indicating that the type of the terminal device is an LPHAP terminal device. The access network device determines, based on the RRC request message, that the type of the terminal device is an LPHAP terminal device.

[0028] The above implementation shows another implementation example in which the access network device determines that the terminal device is an LPHAP terminal device. The terminal device indicates to the access network device that the terminal device is an LPHAP terminal device in an RRC request process.

[0029] In another possible implementation, the access network device determining the configuration information of the TRS for the terminal device includes:

[0030] The access network device receives first indication information from the positioning device, where the first indication information instructs the access network device to configure a TRS resource associated with the SRS resource for the terminal device. The access network device determines the configuration information of the TRS based on the configuration information of the SRS and the first indication information.

[0031] This possible implementation illustrates an example of a specific implementation in which the access network device determines the configuration information of the TRS based on the configuration information of the SRS, in which the access network device may determine the configuration information of the TRS based on the first indication information.

[0032] In this way, an association between the first SRS resource and the first TRS resource of the terminal device is implemented. In this way, after the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device may transmit an SRS by using the first SRS resource to implement positioning of the terminal device. After transmitting the SRS, the terminal device may enter a deep sleep mode. One first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization, the terminal device may transmit the SRS within a short period of time. This reduces the time the terminal device spends maintaining a microsleep mode and reduces the power consumption overhead of the terminal device. In this way, the battery life of the terminal device is improved.

[0033] In another possible implementation, the access network device receiving the first indication information from the positioning device includes: the access network device receiving a positioning information request message from the positioning device, where the positioning information request message includes the first indication information.

[0034] In this possible implementation, the first indication information may be carried in the positioning information request message, in other words, a specific carrier is provided, facilitating the implementation of the solution.

[0035] In another possible implementation, the access network device determining the configuration information of the SRS of the terminal device includes:

[0036] The access network device receives the SRS resource reservation information and second instruction information from the positioning device, where the second instruction information instructs the access network device to configure a TRS resource associated with the SRS resource corresponding to the SRS resource reservation information.

[0037] The access network device determines the configuration information of the SRS based on the SRS resource reservation information.

[0038] The access network device determining the configuration information of the TRS for the terminal device includes:

[0039] The access network device determines the configuration information of the TRS based on the configuration information of the SRS and the second indication information.

[0040] In the above implementation, the access network device configures SRS configuration information for the terminal device based on the SRS resource reservation information. The access network device determines TRS configuration information for the terminal device based on the SRS configuration information and the second indication information. In this manner, an association between the first SRS resource and the first TRS resource of the terminal device is implemented. In this manner, after the terminal device implements downlink time-frequency synchronization by using the TRS received on the TRS resource, the terminal device may transmit an SRS by using the first SRS resource to implement terminal device positioning. After transmitting the SRS, the terminal device may enter deep sleep mode. One first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization, the terminal device may transmit the SRS within a short period of time. This reduces the time the terminal device spends maintaining a microsleep mode and reduces the power consumption overhead of the terminal device. In this manner, the battery life of the terminal device is improved.

[0041] A second aspect of the present application provides a communication processing method, including:

[0042] A terminal device receives SRS configuration information and TRS configuration information from an access network device, where the TRS configuration information is used to configure one or more first TRS resources, and one first TRS resource is between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. The terminal device receives a TRS based on the TRS configuration information. The terminal device transmits an SRS based on the SRS configuration information.

[0043] In the above technical solution, one first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. The terminal device switches from deep sleep mode to micro sleep mode, and the terminal device implements time-frequency tracking by using the TRS received based on the TRS configuration information. The terminal device maintains the micro sleep mode. The terminal device transmits an SRS on the first SRS resource based on the SRS configuration information to implement positioning of the terminal device. After transmitting the SRS, the terminal device may enter deep sleep mode. One first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device may transmit the SRS within a short period of time. This reduces the time the terminal device spends maintaining the micro sleep mode, prevents the terminal device from wasting unnecessary power, and thereby reduces the power consumption overhead of the terminal device. In this way, the battery life of the terminal device is improved.

[0044] In a possible implementation, one first TRS resource exists before the first first SRS resource configured based on the configuration information of the SRS.

[0045] In the above implementation, one first TRS resource exists before the initial first SRS, so that the terminal device performs downlink time-frequency tracking. In this way, the technical solution of the present application can be applied to several more scenarios. For example, before the first SRS resource, the terminal device is in deep sleep mode. The terminal device needs to switch from deep sleep mode to micro-sleep mode and transmit the SRS held in the first SRS resource. In this case, before the first SRS resource, the terminal device needs to perform downlink time-frequency tracking. Therefore, one first TRS resource can be configured before the initial first SRS resource, so that the terminal device performs downlink time-frequency tracking.

[0046] In another possible implementation, the cycle of the first SRS resource is a positive integer multiple of the cycle of the first TRS resource.

[0047] In this implementation, the cycle of the first SRS resource is a positive integer multiple of the cycle of the first TRS resource, ensuring that one first TRS resource exists between two adjacent first SRSs, so that the terminal device performs downlink time-frequency synchronization. In this way, the terminal device can transmit an SRS on the first SRS resource and enter deep sleep mode. In this way, the time spent by the terminal device in microsleep mode is reduced, reducing the power consumption of the terminal device and thereby implementing low-power positioning.

[0048] In another possible implementation, at least one first SRS resource of the multiple first SRS resources configured based on the SRS configuration information is located in an uplink / downlink switch slot, and one first TRS resource is located in the uplink / downlink switch slot in which the first SRS resource is located; at least one first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in the Nth downlink slot before the uplink slot in which the first SRS resource is located, where N is a positive integer; at least one first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in the Nth uplink / downlink switch slot before the uplink slot in which the first SRS resource is located; or at least one first SRS resource of the multiple first SRS resources is located in an uplink / downlink switch slot, and one first TRS resource is located in the Nth downlink slot before the uplink / downlink switch slot in which the first SRS resource is located.

[0049] This possible implementation shows examples of multiple possible positional relationships between the first SRS resource and the first TRS resource. In this way, after the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device can transmit an SRS within a short time and enter a deep sleep state. In this way, the time spent by the terminal device in microsleep mode is reduced, reducing the power consumption of the terminal device and thereby improving the battery life of the terminal device.

[0050] In another possible implementation, the method further comprises:

[0051] The terminal device sends capability information to the access network device, where the capability information includes information about the terminal device that is a type of LPHAP terminal device.

[0052] It can be seen that the above shows an example of a possible implementation in which a terminal device indicates to an access network device that the terminal device is an LPHAP terminal device. The terminal device can indicate to the access network device that the type of the terminal device is an LPHAP terminal device based on the capability information, and does not need to indicate to the access network device that the type of the terminal device is an LPHAP terminal device by defining a new message. This improves the applicability of the solution.

[0053] In another possible implementation, the method further comprises:

[0054] The terminal device sends a preamble sequence to the access network device, where the preamble sequence is used by the terminal device to initiate random access to the access network device, and the preamble sequence indicates that the type of the terminal device is an LPHAP terminal device.

[0055] The above implementation shows another implementation example in which a terminal device indicates to an access network device that the terminal device is an LPHAP terminal device. The access network device determines that the terminal device is an LPHAP terminal device based on the preamble sequence used by the terminal device to initiate random access. There is no need to redefine a new message to send the indication information.

[0056] In another possible implementation, the method further comprises:

[0057] The terminal device sends an RRC request message to the access network device, where the RRC request message includes information indicating that the type of the terminal device is an LPHAP terminal device.

[0114] From the above technical solutions, it can be seen that an access network device determines configuration information of an SRS for a terminal device, and the access network device determines configuration information of a TRS for the terminal device, where the TRS is used by the terminal device to perform time-frequency tracking. The TRS configuration information is used to configure one or more TRS resources, and at least one TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. It can be seen that the at least one first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. The terminal device switches from a deep sleep mode to a micro sleep mode, and the terminal device implements time-frequency tracking by using the TRS received on the TRS resource. The terminal device maintains the micro sleep mode. The terminal device may transmit an SRS on the first SRS resource after the TRS resource to implement positioning of the terminal device. After transmitting the SRS, the terminal device may enter a deep sleep mode. The at least one first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization, the terminal device can transmit the SRS within a short time, thereby reducing the time spent by the terminal device in the micro-sleep mode and preventing the terminal device from wasting unnecessary power consumption, thereby reducing the power consumption overhead of the terminal device, thereby improving the battery life of the terminal device.

[0137] The embodiments of the present application provide a communication processing method and a communication processing device for reducing the power consumption overhead of a terminal device, thereby improving the battery life of the terminal device.

[0138] 1 is a schematic diagram of a communication system according to an embodiment of the present application. Please refer to FIG. 1. The communication system includes a terminal device 101, a next generation NodeB (gNB) 102, a next generation evolved NodeB (ng-eNB) 103, an access and mobility management function (AMF) 104, and a location management function (LMF) 105. The LMF 105 is a network element, module, or component in the NR core network that provides positioning functions to terminal devices.

[0139] Optionally, the communication system further comprises an evolved serving mobile location center (E-SMLC) 106 and a secure user plane location platform (SLP) 107. The E-SMLC 106 is a network element, module, or component in the 4G core network that provides positioning functionality. The SLP 107 is a network element, module, or component in the 4G core network that is configured to process a user plane secure positioning protocol.

[0140] The terminal device 101 communicates with an access network device (e.g., the gNB 102 or the ng-eNB 103 in FIG. 1 ) through a Uu interface. The ng-eNB 103 is an access network device in a Long Term Evolution (LTE) communication system, and the gNB 102 is an access network device in an NR communication system. In the communication system, the access network devices communicate with each other through an Xn interface, and the access network devices communicate with the AMF 104 through an NG-C interface. The AMF 104 communicates with the LMF 105 through an NL1 interface, and the AMF 104 is equivalent to a router for communication between the access network devices and the LMF 105. The LMF 105 is configured to perform positioning calculations for the location of the terminal device.

[0141] 1 merely shows an example in which the communication system includes two access network devices: a gNB and an ng-eNB. However, in practical applications, the communication system may include at least one access network device, which is not specifically limited in the present application.

[0142] The following describes an access network device and a terminal device in a communication system provided in this embodiment of the present application.

[0143] An access network device is a device deployed in a radio access network that provides wireless communication functions to terminal devices. The access network device is a base station, which may be a macro base station, a micro base station (also referred to as a small cell), a relay station, an access point (AP), a wearable device, an in-vehicle device, or the like. A base station may alternatively be a transmission reception point (TRP), a transmission measurement function (TMF), or the like. For example, the base station in this embodiment of the present application may be a base station in new radio (NR). A base station in 5G NR may also be called a transmission reception point (TRP), a transmission point (TP), a next generation NodeB (ng-NB), or an evolved NodeB (eNB) in a long term evolution (LTE) system.

[0144] The terminal device may be a wireless terminal device that can receive scheduling and instruction information from an access network device. The wireless terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or another processing device connected to a wireless modem.

[0145] A terminal device, also referred to as user equipment (UE), mobile station (MS), mobile terminal (MT), or the like, is a device including a wireless communication function (i.e., providing a user with voice / data connectivity), such as a handheld device with a wireless connection function or an in-vehicle device. Currently, some examples of terminal devices are a mobile phone, a tablet computer, a laptop computer, a palmtop computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, and a wireless terminal in a smart home.

[0146] In this embodiment of the present application, in the communication system shown in FIG. 1 , LMF is the name in the current communication system. In future communication systems, the name of LMF may change as the communication system evolves. Therefore, the LMF will be referred to as a positioning device hereinafter to describe the embodiment of the present application. The positioning device is configured to perform positioning calculations on the location of a terminal device. In the current communication system or the future communication system, a functional network element having a different name and a function similar to that of a positioning device can be understood as a positioning device in the embodiment of the present application and is applicable to the communication processing method provided in the embodiment of the present application.

[0147] The following describes the technical solutions of the present application with reference to specific embodiments.

[0148] 2 is a schematic diagram of an embodiment of a communication processing method according to an embodiment of the present application. Please refer to FIG. 2. The communication processing method includes the following steps:

[0149] 201: An access network device determines configuration information of an SRS of a terminal device.

[0150] The SRS resources configured based on the SRS configuration information include a plurality of first SRS resources, each occupying one or more time domain symbols, and the SRS resource in a transmission opportunity when the terminal device transmits the SRS is referred to as the first SRS resource.

[0151] For example, as shown in Figure 3A, the SRS resources configured based on the SRS configuration information include multiple first SRS resources. Each first SRS resource occupies some or all of the time domain symbols of one uplink slot. A slot in which one first SRS resource is located can be understood as a transmission opportunity when a terminal device transmits an SRS.

[0152] For example, as shown in FIG. 3B, the SRS resources configured based on the SRS configuration information include multiple first SRS resources. Each first SRS resource occupies one time-domain symbol in one uplink / downlink switch slot. A slot in which one first SRS resource is located can be understood as a transmission opportunity when a terminal device transmits an SRS.

[0153] Optionally, the configuration information of the SRS includes cycle information of the first SRS resource.

[0154] For example, as shown in Figure 3A, the time interval between the first time domain symbols occupied by two adjacent first SRS resources is 20 slots, or in other words, the cycle of the first SRS resource can be understood as 20 slots.

[0155] For example, as shown in Figure 3C, the time interval between the first time domain symbols occupied by two adjacent first SRS resources is 40 slots, or in other words, the cycle of the first SRS resource can be understood as 40 slots.

[0156] It should be noted that in addition to the plurality of first SRS resources, the SRS resources configured based on the SRS configuration information may further include another SRS resource of the terminal device. This is not specifically limited in the present application. For example, the another SRS resource is a second SRS resource or a third SRS resource. The another SRS resource is similar to the first SRS resource. This is not described in this specification. For example, the second SRS resource is a periodic SRS resource, and the positional relationship between the second SRS resource and the first TRS resource is similar to the positional relationship between the first SRS resource and the first TRS resource. For details, please refer to the related description of the positional relationship between the first SRS resource and the first TRS resource below.

[0157] In a possible implementation, the access network device is a serving base station of a terminal device, and the access network device receives an SRS request message from a positioning device. The access network device determines SRS configuration information for the terminal device based on the SRS request message. Alternatively, the SRS request message includes reference configuration information for an SRS recommended by the positioning device, and the access network device determines the SRS configuration information based on the reference configuration information for the SRS. For example, the positioning device is an LMF.

[0158] It should be noted that the ratio of the number of downlink slots, the number of uplink / downlink switch slots, and the number of downlink slots in a communication system to which the present application is applicable is not limited. In the schematic diagrams of the first SRS resource and the first TRS resource in the present application, an example in which the ratio of the number of downlink slots, the number of uplink / downlink switch slots, and the number of uplink slots in the communication system may be 7:1:2 is used for explanation. An example in which an uplink / downlink switch slot includes two downlink time domain symbols, four switch isolation (GAP) symbols, and eight uplink time domain symbols is used for explanation. Specifically, the ratio of the number of downlink time domain symbols, the number of GAP symbols, and the number of uplink time domain symbols in an uplink / downlink switch slot is not limited in the present application.

[0159] In another possible implementation, the access network device is a neighbor base station of the terminal device, and the access network device receives SRS resource reservation information from the positioning device. The access network device determines SRS configuration information based on the SRS resource reservation information. For a specific determination process, please refer to the related description in the embodiment shown in Figure 10 below.

[0160] 202: The access network device determines configuration information of the TRS for the terminal device.

[0161] The TRS is used by the terminal device to perform time-frequency tracking. For example, the access network device configures a channel state information reference signal (CSI-RS) for the terminal device, where the CSI-RS is used by the terminal device to perform time-frequency tracking.

[0162] The TRS configuration information is used to configure one or more primary TRS resources, where one primary TRS resource occupies one or more time domain symbols.

[0163] For example, as shown in Figure 3A, the first TRS resource is located in a downlink slot, and may occupy one or more time domain symbols in the downlink slot.

[0164] For example, as shown in FIG. 3B, the first TRS resource may be located in the uplink / downlink switch slot, and the first TRS resource may occupy one time domain symbol in the uplink / downlink switch slot.

[0165] It should be noted that the TRS resources configured based on the TRS configuration information may include one or more first TRS resources and may also include another TRS resource of the terminal device. This is not specifically limited in this application. For example, the another TRS resource may be a second TRS resource or a third TRS resource. The another TRS resource may be the same as the first TRS resource. In this application, the first TRS resource is used as an example to explain the technical solution of this application. For example, the second TRS resource may have a cycle, and the cycle of the second TRS resource may be the same as the cycle of the first TRS resource. One second TRS resource exists between two adjacent first SRS resources. In other words, the positional relationship between the first SRS resource and the second TRS resource is the same as the positional relationship between the first SRS resource and the first TRS resource. Details will not be described again in this specification.

[0166] One first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the configuration information of the SRS.

[0167] For example, as shown in Figure 3A, two adjacent first SRS resources configured based on the SRS configuration information are located in slot 8 and slot 18, respectively. One first TRS resource exists between the two adjacent first SRS resources. As shown in Figure 3A, the first TRS resource is located in slot 16.

[0168] Optionally, one first TRS resource exists before the first first SRS resource configured based on the configuration information of the SRS.

[0169] For example, before the first SRS resource, the terminal device is in deep sleep mode. The terminal device needs to switch from deep sleep mode to microsleep mode and transmit the SRS stored in the first SRS resource. In this case, before the first SRS resource, the terminal device needs to perform downlink time-frequency tracking. Therefore, one first TRS resource may be configured before the first first SRS resource, so that the terminal device performs downlink time-frequency tracking.

[0170] It should be noted that there may be no TRS resource before the first SRS resource configured based on the SRS configuration information. For example, before the first SRS resource, the terminal device may be in a connected state, in other words, the terminal device has implemented downlink time-frequency synchronization, and no TRS resource may need to be configured before the first SRS resource.

[0171] Optionally, the cycle of the first SRS resource is a positive integer multiple of the cycle of the first TRS resource.

[0172] For example, as shown in Figure 3A, the time interval between the first time domain symbols occupied by two adjacent first SRS resources is 20 slots, and the time interval between the first time domain symbols occupied by two adjacent first TRS resources is also 20 slots. In other words, the cycle of the first SRS resource is the same as the cycle of the first TRS resource.

[0173] For example, as shown in Figure 3C, the time interval between the first time domain symbols occupied by two adjacent first SRS resources is 40 slots, and the time interval between the first time domain symbols occupied by two adjacent first TRS resources is 20 slots, in other words, the cycle of the first SRS resource is twice the cycle of the first TRS resource.

[0174] In some implementations, the SRS resources configured based on the SRS configuration information include a plurality of first SRS resources, and the following describes a plurality of possible positional relationships between the plurality of first SRS resources and the first TRS resource.

[0175] 1. At least one first SRS resource of the multiple first SRS resources configured based on the SRS configuration information is located in an uplink / downlink switch slot, and one first TRS resource is located in the uplink / downlink switch slot where the first SRS resource is located.

[0176] In some implementations, each first SRS resource of the multiple first SRS resources is located in an uplink / downlink switch slot, and one first TRS resource is located in the uplink / downlink switch slot in which the first SRS resource is located.

[0177] For example, as shown in Figure 4A, each first SRS resource is located in an uplink / downlink switch slot, and the first SRS resource occupies the last time-domain symbol in the uplink / downlink switch slot. As shown in Figure 4A, slot 8 is the uplink / downlink switch slot, the first SRS resource is located in slot 8, and the first TRS resource occupies time-domain symbol 1 in slot 8.

[0178] Optionally, the first TRS resource and the second TRS resource are two adjacent TRS resources configured based on TRS configuration information, and there may be one or more time domain symbols between the first TRS resource and the second TRS resource, thereby improving the accuracy of time-frequency synchronization performed by the terminal device.

[0179] For example, as shown in Figure 4A, the first TRS resource is located in time domain symbol 1 in slot 8, and the second TRS resource is located in time domain symbol 5 in slot 8. There are three time domain symbols between time domain symbol 1 and time domain symbol 5. This helps the terminal device to receive the TRS on the first TRS resource and the second TRS resource separately, thereby improving the accuracy of the time-frequency synchronization performed by the terminal device.

[0180] After the terminal device switches from deep sleep mode to micro sleep mode, the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource. The terminal device maintains the micro sleep mode. The terminal device may transmit an SRS and implement terminal device positioning by using the first SRS resource at the time the SRS is transmitted (i.e., the slot in which the first SRS resource is located). After the terminal device transmits the SRS, the terminal device may enter deep sleep mode. The first SRS resource and the first TRS resource are located in the same uplink / downlink switch slot. Therefore, the time spent by the terminal device maintaining the micro sleep mode and waiting for the transmission of the SRS is short. For example, in the example shown in FIG. 4A, the time spent by the terminal device maintaining the micro sleep mode and waiting for the transmission of the SRS is 11 time domain symbols. In this way, the time spent by the terminal device maintaining the micro sleep mode is reduced, reducing the power consumption of the terminal device and thereby improving the battery life of the terminal device.

[0181] 2. At least one first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in an Nth downlink slot before the uplink slot in which the first SRS resource is located, where N is an integer greater than or equal to 1.

[0182] In some implementations, each of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in the Nth downlink slot before the uplink slot in which the first SRS resource is located.

[0183] For example, as shown in Figure 4B, each first SRS resource is located in an uplink slot and occupies some or all of the time domain symbols of the uplink slot. As shown in Figure 4B, slot 9 is the uplink slot, the first SRS resource is located in slot 9, the first downlink slot before slot 9 is slot 7, and the first TRS resource is located in time domain symbol 0 in slot 7.

[0184] Optionally, the first TRS resource and the second TRS resource are two adjacent TRS resources configured based on TRS configuration information, and there may be one or more time domain symbols between the first TRS resource and the second TRS resource, thereby improving the accuracy of time-frequency synchronization performed by the terminal device.

[0185] For example, as shown in FIG. 4B, the first TRS resource is located in time domain symbol 0 in slot 7. The second TRS resource is located in time domain symbol 4 in slot 7. There are three time domain symbols between time domain symbol 0 and time domain symbol 4.

[0186] After the terminal device switches from deep sleep mode to micro sleep mode, the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource. The terminal device maintains the micro sleep mode. The terminal device may transmit an SRS and implement terminal device positioning by using the first SRS resource at the time the SRS is transmitted (i.e., the slot in which the first SRS resource is located). After the terminal device transmits the SRS, the terminal device may enter deep sleep mode. The first SRS resource is located in the uplink slot, and the first TRS resource is located in the Nth downlink slot before the uplink slot. Therefore, the time spent by the terminal device maintaining the micro sleep mode and waiting to transmit the SRS is short. For example, in the example shown in FIG. 4B, after the terminal device completes downlink time-frequency synchronization, the terminal device may be in micro sleep mode at the uplink / downlink switch slot and quickly transmit the SRS on the first SRS resource. In this way, the time spent by the terminal device in maintaining the micro-sleep mode is reduced, reducing the power consumption of the terminal device and thereby improving the battery life of the terminal device.

[0187] 3. At least one first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in the Nth uplink / downlink switch slot before the uplink slot in which the first SRS resource is located, where N is an integer greater than or equal to 1.

[0188] In some implementations, each first SRS resource of the multiple first SRS resources is located in an uplink slot, and one first TRS resource is located in a first uplink downlink switch slot before the uplink slot in which the first SRS resource is located.

[0189] For example, as shown in Figure 4C, each first SRS resource is located in an uplink slot and occupies some or all of the time domain symbols of the uplink slot. As shown in Figure 4C, slot 9 is the uplink slot, the first SRS resource is located in slot 9, the first uplink / downlink switch slot before slot 9 is slot 8, and the first TRS resource is located in time domain symbol 1 in slot 8.

[0190] Optionally, the first TRS resource and the second TRS resource are two adjacent TRS resources configured based on TRS configuration information. There may be one or more time domain symbols between the first TRS resource and the second TRS resource, improving the accuracy of time-frequency synchronization performed by the terminal device. For example, as shown in FIG. 4C , the first TRS resource is located in time domain symbol 1 in slot 8, and the second TRS resource is located in time domain symbol 5 in slot 8. There are three time domain symbols between time domain symbol 1 and time domain symbol 5.

[0191] After the terminal device switches from deep sleep mode to microsleep mode, the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource. The terminal device maintains the microsleep mode. The terminal device may transmit an SRS and implement terminal device positioning by using the first SRS resource at the time the SRS is transmitted (i.e., the slot in which the first SRS resource is located). After the terminal device transmits the SRS, the terminal device may enter deep sleep mode. The first SRS resource is located in the uplink slot, and the first TRS resource is located in the Nth uplink / downlink switch slot before the uplink slot. Therefore, the time spent by the terminal device maintaining the microsleep mode and waiting to transmit the SRS is short. For example, in the example shown in FIG. 4C, after the terminal device completes downlink time-frequency synchronization, the terminal device may be in microsleep mode at the 13th time domain symbol and quickly transmit the SRS on the first SRS resource. In this way, the time spent by the terminal device in maintaining the micro-sleep mode is reduced, reducing the power consumption of the terminal device and thereby improving the battery life of the terminal device.

[0192] 4. At least one first SRS resource of the multiple first SRS resources is located in an uplink / downlink switch slot, and one first TRS resource is located in the Nth downlink slot before the uplink slot in which the first SRS resource is located.

[0193] For example, as shown in Figure 4D, each first SRS resource is located in an uplink slot and occupies some or all of the time domain symbols of the uplink slot. As shown in Figure 4D, slot 8 is the uplink / downlink switch slot, the first SRS resource is located in slot 8, the first downlink slot before slot 8 is slot 7, and the first TRS resource is located in time domain symbol 1 in slot 7.

[0194] It should be noted that, optionally, the TRS resource configured based on the TRS configuration information may be located multiple downlink slots before the uplink slot in which the first SRS resource resides.

[0195] For example, as shown in Figure 4E, slot 7 is an uplink / downlink switch slot, a first SRS resource is located in slot 7, one first TRS resource and one second TRS resource are located in the first downlink slot before slot 7 (i.e., slot 6), the first TRS resource is located in time domain symbol 2 in slot 6, and the second TRS resource is located in time domain symbol 5 in slot 6. One third TRS resource is located in the second downlink slot before slot 7 (i.e., slot 5). In this way, the accuracy of time-frequency synchronization performed by the terminal device is improved.

[0196] After the terminal device switches from deep sleep mode to micro sleep mode, the terminal device implements downlink time-frequency synchronization by using the TRS received on the first TRS resource. The terminal device maintains the micro sleep mode. The terminal device may transmit an SRS and implement terminal device positioning by using the first SRS resource at the time the SRS is transmitted (i.e., the slot in which the first SRS resource is located). After the terminal device transmits the SRS, the terminal device may enter deep sleep mode. The first SRS resource is located in the uplink / downlink switch slot, and the first TRS resource is located in the Nth downlink slot before the uplink / downlink switch slot. Therefore, the time spent by the terminal device maintaining the micro sleep mode and waiting to transmit the SRS is short. For example, in the example shown in FIG. 4D, after the terminal device completes downlink time-frequency synchronization, the terminal device may be in micro sleep mode for several time domain symbols and quickly transmit the SRS on the first SRS resource. In this way, the time spent by the terminal device in maintaining the micro-sleep mode is reduced, reducing the power consumption of the terminal device and thereby improving the battery life of the terminal device.

[0197] With reference to the above related descriptions of the SRS configuration information and the TRS configuration information, it can be seen that the positional relationship between the first SRS resource and the first TRS resource and the relationship between the cycle of the first SRS resource and the cycle of the first TRS resource can be understood as an association between the SRS resource and the TRS resource of the terminal device.

[0198] In some implementations, the terminal device determines configuration information of the TRS for the terminal device based on configuration information of the SRS.

[0199] Specifically, the terminal device may determine configuration information of the TRS for the terminal device based on the configuration information of the SRS, and implement an association between the SRS resource of the terminal device and the first TRS resource.

[0200] Optionally, if the access network device has configured a corresponding TRS for the terminal device before step 202, the access network device determines whether the TRS resource already configured for the terminal device is associated with the configured SRS resource based on the configuration information of the SRS. If the TRS resource is not associated with the SRS resource, the access network device executes step 202. Specifically, the access network device may determine whether the SRS resource is associated with the TRS resource by referring to the location relationship between the SRS resource and the TRS resource and the relationship between the cycle of the SRS resource and the cycle of the TRS resource. It should be noted that if the SRS resource is associated with the TRS resource, the access network device does not need to re-determine the configuration information of the TRS for the terminal device.

[0201] Optionally, the embodiment shown in FIG. 2 further includes step 201a, which may be performed before step 201.

[0202] 201a: The access network device determines that the type of the terminal device is an LPHAP terminal device.

[0203] An LPHAP terminal device has a low-power, high-accuracy positioning function. Compared with a common terminal device (i.e., a non-LPHAP terminal device), an LPHAP terminal device has a low-power or long-battery-life capability. Alternatively, an LPHAP terminal device has a low-power positioning requirement or a long-battery-life requirement. A non-LPHAP terminal device may not have a low-power or long-battery-life capability. Alternatively, a non-LPHAP terminal device does not have a low-power positioning requirement or a long-battery-life requirement.

[0204] Optionally, the low power or long battery life capabilities include: the terminal device can enter a deep sleep mode, in which the terminal device only needs to maintain a very low clock current.

[0205] There are several ways to determine step 201a, please refer to the following related descriptions in Figures 5 to 9 for details.

[0206] After the access network device determines that the terminal device is an LPHAP terminal device, the access network device may determine configuration information of the TRS for the terminal device based on the configuration information of the SRS.

[0207] Optionally, the embodiment shown in FIG. 2 further includes step 203. Step 203 may be performed before step 201.

[0208] 203: The access network device sends the configuration information of the SRS and the configuration information of the TRS to the terminal device.

[0209] For the related description of the configuration information of the SRS and the configuration information of the TRS, please refer to the related description in step 201 and step 202. The details will not be described again in this specification.

[0210] For example, the access network device is a serving base station of a terminal device, and the access network device transmits the configuration information of the SRS and the configuration information of the TRS to the terminal device. The access network device may transmit the configuration information of the SRS and the configuration information of the TRS to the terminal device by using the same message or different messages. For example, the access network device transmits the configuration information of the SRS and the configuration information of the TRS to the terminal device by using the same radio resource control (RRC) message.

[0211] 204: The terminal device receives the TRS based on the configuration information of the TRS.

[0212] For example, as shown in FIG. 4A, the terminal device receives a TRS from the access network device on time domain symbol 1 in slot 8 (uplink / downlink switch slot), and performs downlink time-frequency tracking by using the TRS to implement downlink time-frequency synchronization of the terminal device.

[0213] Optionally, the terminal device may receive a TRS from the access network device on time domain symbol 5 in slot 8 to ensure downlink time-frequency synchronization of the terminal device.

[0214] 205: The terminal device transmits the SRS based on the configuration information of the SRS.

[0215] For example, as shown in FIG. 4A, the terminal device transmits an SRS on time domain symbol 13 in slot 8 to the access network device to perform positioning of the terminal device.

[0216] In this embodiment of the present application, an access network device determines SRS configuration information for a terminal device, and the access network device determines the TRS configuration information for the terminal device. The TRS configuration information is used to configure one or more first TRS resources, and one first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. It is determined that one first TRS resource exists between two adjacent first SRS resources in the SRS resources configured based on the SRS configuration information. The terminal device switches from deep sleep mode to micro sleep mode, and the terminal device implements time-frequency tracking by using the TRS received on the first TRS resource. The terminal device maintains the micro sleep mode. The terminal device may transmit an SRS on the first SRS resource after the first TRS resource to implement positioning of the terminal device. After transmitting the SRS, the terminal device may enter deep sleep mode. One first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization by using the TRS received on the first TRS resource, the terminal device may transmit an SRS within a short time, thereby reducing the time spent by the terminal device in microsleep mode and preventing the terminal device from wasting unnecessary power, thereby reducing the power consumption of the terminal device, thereby improving the battery life of the terminal device.

[0217] Referring to Figures 5 to 7, the following describes several possible implementations in which an access network device determines that the type of a terminal device is an LPHAP terminal device.

[0218] 5 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Please refer to FIG. 5. The communication processing method includes the following steps:

[0219] Step 501: The terminal device sends capability information of the terminal device to the access network device, and the access network device correspondingly receives capability information from the terminal device.

[0220] The capability information includes information indicating that the type of the terminal device is an LPHAP terminal device.

[0221] For example, the terminal device sends a capability information (UE capability information) report message to the access network device, where the capability information report message includes indication information indicating that the type of the terminal device is an LPHAP terminal device.

[0222] Optionally, the embodiment shown in FIG. 5 further includes step 501a, which is performed before step 501.

[0223] 501a: The access network device sends a capability information request to the terminal device, and in response, the terminal device receives a capability information request from the access network device.

[0224] For example, the access network device sends a capability information request (UE capability enquiry) message to the terminal device to request capability information from the terminal device.

[0225] 502: The access network device determines, based on the capability information, that the type of the terminal device is an LPHAP terminal device.

[0226] Specifically, the access network device determines that the terminal device is an LPHAP terminal device based on information indicating that the type of the terminal device is an LPHAP terminal device.

[0227] It can be seen that Figure 5 shows an example of implementation in which an access network device determines that a terminal device is an LPHAP terminal device. The terminal device can indicate to the access network device that the type of the terminal device is an LPHAP terminal device based on the capability information, and does not need to indicate to the access network device that the type of the terminal device is an LPHAP terminal device by defining a new message. This improves the applicability of the solution.

[0228] 6 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Please refer to FIG. 6. The communication processing method includes the following steps:

[0229] 601: A terminal device sends a preamble sequence (random access) to an access network device, and in response, the access network device receives the preamble sequence from the terminal device.

[0230] The preamble sequence is used by the terminal device to initiate random access to the access network device.

[0231] Specifically, a terminal device initiates random access to an access network device by using a reserved preamble sequence. The reserved preamble sequence is used by an LPHAP terminal device to initiate random access. The access network device can determine that the terminal device is an LPHAP terminal device based on the reserved preamble sequence.

[0232] For example, if a cell has 64 preamble sequences, a common terminal device initiates random access by using 50 preamble sequences, and an LPHAP terminal device initiates random access by using the remaining 14 preamble sequences. It can be seen that an access network device can determine whether a terminal device is an LPHAP terminal device by identifying the preamble sequence.

[0233] 602: The access network device identifies the type of the terminal as an LPHAP terminal device based on the preamble sequence.

[0234] It can be seen that Figure 6 shows another implementation example in which the access network device determines that the terminal device is an LPHAP terminal device. The access network device determines that the terminal device is an LPHAP terminal device based on the preamble sequence used by the terminal device to initiate random access. There is no need to redefine a new message to send indication information.

[0235] 7 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Referring to FIG. 7, the communication processing method includes the following steps:

[0236] 701: A terminal device sends an RRC request message to an access network device. The RRC request message includes information indicating that the type of the terminal device is an LPHAP terminal device. In response, the access network device receives an RRC request message from the terminal device.

[0237] In some implementations, the RRC request message may be an RRC setup request message or an RRC resume request message.

[0238] For example, the RRC setup request message is message 3 (Msg3) in a four-step random access process, or message 2 (Msg2) in a two-step random access process, which is not specifically limited in this application.

[0239] Optionally, the RRC setup request message includes indication information indicating that the type of the terminal device is an LPHAP terminal device. Alternatively, the RRC setup request message includes a cause value, and the cause value is a low power positioning request. The cause value instructs the terminal device to initiate RRC setup and perform low power positioning.

[0240] 702: The access network device determines, based on the RRC request message, that the type of the terminal device is an LPHAP terminal device.

[0241] The access network device determines that the terminal device is an LPHAP terminal device based on information carried in the RRC request message indicating that the type of the terminal device is an LPHAP terminal device.

[0242] It can be seen that Figure 7 shows another implementation example in which the access network device determines that the terminal device is an LPHAP terminal device. In an RRC request process, the terminal device indicates to the access network device that the terminal device is an LPHAP terminal device.

[0243] With reference to FIGS. 8 to 10, the following describes two possible implementations of step 202 in the embodiment shown in FIG. 2, in which the access network device determines the configuration information of the TRS for the terminal device.

[0244] 8 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Please refer to FIG. 8. The communication processing method includes the following steps:

[0245] 801: A positioning device sends first instruction information to an access network device, where the first instruction information instructs the access network device to configure a TRS resource associated with an SRS resource for a terminal device.

[0246] For the relationship between SRS resources and TRS resources, please refer to the related description in step 201. The details will not be described again in this specification. The positioning device can be an LMF.

[0247] In step 801, the access network device may be a serving base station of the terminal device. The first indication information may be carried in the positioning information request message or may be carried in the measurement request message. For a related process of carrying the first indication information in the positioning information request message, please refer to the related description in Figure 9 below.

[0248] 802: The access network device determines configuration information of the TRS for the terminal device based on the first indication information and the configuration information of the SRS.

[0249] Specifically, after the access network device receives the first indication information, the access network device may determine to configure a TRS resource associated with the SRS resource for the terminal device. The access network device determines the TRS configuration information for the terminal device based on the SRS configuration information. In this way, the association between the SRS resource and the TRS resource of the terminal device is implemented.

[0250] 9 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Please refer to FIG. 9. The communication processing method includes the following steps:

[0251] 901: A positioning device sends a positioning information request message to an access network device, and in response, the access network device receives a positioning information request message from the positioning device.

[0252] The positioning information request message includes first indication information. For a related description of the first indication information, please refer to the related description in step 801 in the embodiment shown in Figure 8. The details will not be described again in this specification. For example, the positioning device is an LMF.

[0253] Optionally, the embodiment shown in Figure 9 further includes step 901a, which may be performed before step 901.

[0254] 901a: The terminal device sends capability information to the positioning device. The capability information includes information indicating that the type of the terminal device is an LPHAP terminal device. In response, the positioning device receives capability information from the terminal device.

[0255] Specifically, the terminal device sends a capability information report message to the positioning device by using the access network device, and the capability information report message includes information indicating that the type of the terminal device is an LPHAP terminal device.

[0256] Optionally, the embodiment shown in FIG. 9 further includes step 901b, which may be performed before step 901a.

[0257] 901b: The positioning device sends a capability information request to the terminal device, and in response, the terminal device receives a capability information request from the positioning device.

[0258] The capability information request requests capability information from the terminal device.

[0259] Specifically, the positioning device sends a capability information request message to the terminal device by using the access network device, where the capability information request message requests capability information of the terminal device.

[0260] 902: The access network device determines configuration information of a TRS for the terminal device based on the first indication information and the configuration information of the SRS.

[0261] Step 902 is the same as step 802 in the embodiment shown in Figure 8. For details, please refer to the related description in step 802 in the embodiment shown in Figure 8. The details will not be described again in this specification.

[0262] In this application, optionally, the access network device is a neighbor base station of the terminal device. Optionally, with reference to the embodiment shown in Figure 10, the following describes a possible implementation in which the access network device determines the configuration information of the SRS and the configuration of the TRS.

[0263] FIG. 10 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Referring to Figure 10, the communication processing method includes the following steps.

[0264] 1001: A positioning device sends SRS resource reservation information and second indication information to an access network device.

[0265] The second instruction information instructs the access network device to configure a TRS resource associated with the SRS resource corresponding to the SRS resource reservation information for the terminal device, for example, the positioning device is an LMF.

[0266] Optionally, the SRS resource reservation information includes configuration information of the SRS resource of the terminal device.

[0267] Specifically, the access network device is a neighboring base station of the terminal device, and the positioning device may send new radio positioning protocol A (NRPPa) signaling to the neighboring base station, where the NRPPa signaling includes SRS resource reservation information and second indication information.

[0268] 1002: The access network device determines configuration information of the SRS based on the SRS resource reservation information.

[0269] In a possible implementation, the access network device may use the SRS resource configuration information in the SRS resource reservation information as the SRS configuration information of the terminal device.

[0270] In another possible implementation, the access network device may configure SRS configuration information for the terminal device based on the SRS resource configuration information in the SRS resource reservation information.

[0271] 1003: The access network device determines configuration information of the TRS for the terminal device based on the configuration information of the SRS and the second indication information.

[0272] The access network device identifies the terminal device as an LPHAP terminal device by using the second indication information. The access network device may determine TRS configuration information for the terminal device based on the SRS configuration information, and implement an association between the SRS resource and the TRS resource of the terminal device.

[0273] It should be noted that the access network device is a neighbor base station of the terminal device. After the access network device determines the SRS configuration information and the TRS configuration information for the terminal device, the access network device can send the SRS configuration information and the TRS configuration information to the terminal device by using another device.

[0274] In the above technical solution, the neighboring base station configures SRS configuration information for the terminal device, and the neighboring base station determines TRS configuration information for the terminal device based on the SRS configuration information and the second indication information. In this way, an association between the first SRS resource and the first TRS resource of the terminal device is implemented. After the terminal device moves from the serving cell to the neighboring cell, the terminal device does not need to re-access the network to request a TRS resource and can perform downlink time-frequency synchronization by using the first TRS resource configured by the neighboring cell. The terminal device enters a microsleep mode, and can implement time-frequency tracking by using the TRS received on the first TRS resource. The terminal device can then transmit an SRS on the first SRS resource after the first TRS resource to implement terminal device positioning. After transmitting the SRS, the terminal device can enter a deep sleep mode. One first TRS resource exists between two adjacent first SRS resources. After implementing time-frequency synchronization, the terminal device can transmit an SRS within a short period of time. This reduces the time the terminal device spends in maintaining the micro-sleep mode and reduces the power consumption overhead of the terminal device, thus improving the battery life of the terminal device.
