[0003] The R17 standard defines the following: A terminal device may measure the frequency layer of the positioning reference signal (PRS) based on mode 2 of the measurement gap (MG) within, for example, a positioning reference signal processing window (PPW).

T2 can only be located within the length of the PPW. In this case, data reception by the terminal device is significantly affected, but the processing time of the terminal device to measure the PRS frequency layer is reduced.

This is not limited to the embodiments of this application.

[0098] As an example, and not an limitation, in the embodiments of this application, the terminal device may alternatively be a wearable device. A wearable device may also be called a wearable intelligent device, and is a general term for wearable devices intelligently designed and developed for everyday wear using wearable technology, such as eyeglasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that can be worn directly on the body or incorporated into the wearer's clothing or accessories. A wearable device is not only a hardware device but also implements powerful functionality through software support, data interaction, and cloud interaction. In a broad sense, a wearable intelligent device includes large, multifunctional devices that can implement full or partial functionality without relying on a smartphone, such as smartwatches and smart glasses, and devices that focus on only one type of application function and need to be used with other devices such as smartphones, such as various smart bands or smart jewelry for monitoring physical signs.

[0099] Additionally, in embodiments of this application, the terminal device may be a terminal device in an IoT system. IoT is an important part of the future development of information technology. The main technical feature of IoT is the use of communication technologies to connect things to a network and implement an intelligent network for interconnecting people and machines or things.

[0100] In embodiments of this application, the device configured to implement the functions of a terminal device may be a terminal device, or it may be a device that can assist the terminal device in implementing its functions, such as a chip system or a chip. The device may be installed within the terminal device. In embodiments of this application, the chip system may include a chip, or it may include a chip and another separate device.

[0101] The network device in the embodiments of this application may be a device configured to communicate with a terminal device. The network device may be a base transceiver station (BTS) in a global system for mobile communications (GSM) or code division multiple access (CDMA), a node B (NB) in a wideband code division multiple access (WCDMA) system, an evolved node B (eNB, or eNodeB) in LTE, or a radio controller in a cloud radio access network (CRAN) scenario. Alternatively, the network device may be a relay station, an access point, an in-vehicle device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, or one antenna panel or group of antenna panels (including multiple antenna panels) of a base station in a 5G system. Alternatively, the network device may be a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU). This is not limited to the embodiments of this application.

[0102] In some configurations, the gNB may include a central unit (CU) and a DU. The gNB may further include an active antenna unit (AAU). The CU implements some of the functions of the gNB, and the DU implements some of the functions of the gNB. For example, the CU is responsible for handling non-real-time protocols and services and implements the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services and implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements some physical layer processing functions, radio frequency processing, and functions related to the active antenna. Information in the RRC layer is ultimately converted to information in the PHY layer, or converted from information in the PHY layer. Therefore, in this architecture, higher-layer signaling, such as RRC layer signaling, may also be considered to be transmitted by the DU or by the DU and AAU. A network device may be understood to be a device comprising one or more CU nodes, DU nodes, and AAU nodes. Additionally, a CU may be classified as a network device in an access network (RAN) or as a network device in a core network (CN). This is not limited to the present application.

[0103] In embodiments of this application, a terminal device or network device includes a hardware layer, an operating system layer operating on the hardware layer, and an application layer operating 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 may be one or more types of computer operating systems that implement service processing through processes, for example, a Linux operating system, a UNIX operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as a browser, an address book, document processing software, and instant messaging software. Additionally, the specific structure of an executable of the method provided in embodiments of this application is not particularly limited to embodiments of this application, as long as a program that records the code of the method provided in embodiments of this application is operated to perform communication according to the method provided in embodiments of this application. For example, an executable of the method provided in embodiments may be a terminal device or a network device, or it may be a functional module that can call and execute a program on a terminal device or network device.

[0104] The Location Management Function (LMF) plays a role in supporting various types of location services related to terminal devices, including the execution of terminal device positioning and the transmission of auxiliary data to terminal devices. The LMF may exchange signals with network devices, such as gNBs, and terminal devices. For example, information is exchanged between the LMF and gNB using New Radio Positioning Protocol Annex (NRPPa) messages. For example, positioning reference signal (PRS) or sounding reference signal (SRS) configuration information, cell timing, cell location information, etc., are obtained. In another example, terminal device capability information, auxiliary information, measurement information, etc., are transferred between the LMF and terminal devices using LTE Positioning Protocol (LPP) messages.

[0105] To facilitate understanding of the embodiments of this application, the terminology used herein is briefly explained.

[0106] 1.PRS frequency layer The RRS frequency layer may be a set of PRS resource sets, each having common parameters set using signaling, and the signaling may be an NR-DL-PRS-Positioning Frequency Layer.

[0107] 1.PRS frequency layer PRS The frequency layer may be a set of PRS resource sets, each having common parameters set using signaling, and the signaling may be an NR-DL-PRS-Positioning Frequency Layer.

[0108] 3. Measurement time window The measurement time window may be a measurement gap (MG), a positioning reference signal processing window (PPW), or another time window. This is not limited to the present application. Within the measurement time window, the terminal device may determine the measurement time of the PRS frequency layer based on different modes. The specific modes used by the terminal device to determine the measurement time of the PRS frequency layer within the measurement time window are not limited to the embodiments of this application. For example, in the MG, the terminal device may measure the measurement time of the PRS frequency layer in mode 1 or in mode 2. In another example, in the PPW, the terminal device may measure the measurement time of the PRS frequency layer in mode 1 or in mode 2. The PRS frequency layer may be configured by an LMF for the terminal device, and the PPW and MG may be configured by a network device for the terminal device.

[0109] In the embodiments of this application, when the measurement time window is PPW, the length of the measurement time window is the length of PPW, or when the measurement time window is MG, the length of the measurement time window is a length other than 0.5 ms or 0.25 ms before and after the length of MG.

[0110] 4. {N,T} {N,T} is a capability reported to the LMF by the terminal device and introduced in the R16 standard, where N is the terminal device's duration capability for measuring the PRS frequency layer, and T is the terminal device's processing time capability for measuring the PRS frequency layer. {N,T} is associated with Mode 1, which is used when the terminal device determines the measurement time of the PRS frequency layer. T may be within or outside the length of the measurement time window. When T is outside the length of the measurement time window, the impact on the terminal device's data reception is small, but the processing time of the terminal device for measuring the PRS frequency layer increases.

[0111] {N2,T2}{N2,T2} is a capability reported to the LMF by the terminal device and introduced in the R17 standard, where N2 is the terminal device's duration capability for measuring the PRS frequency layer, and T2 is the terminal device's processing time capability for measuring the PRS frequency layer. {N2,T2} is associated with Mode 2, which is used when the terminal device determines the measurement time of the PRS frequency layer. T2 is within the length of the measurement time window. In this case, data reception by the terminal device is greatly affected, but the processing time of the terminal device for measuring the PRS frequency layer is reduced. Thus, measurement of the PRS frequency layer by the terminal device based on Mode 2 is a low-latency measurement.

[0112] In conventional technology, when multiple PRS frequency layers are present, how a terminal device determines the total measurement time for measuring at least one PRS frequency layer based on Mode 2 is not currently addressed in relevant solutions.

[0113] In view of the aforementioned technical challenges, this application provides a communication method that enables a terminal device to determine the total measurement time for measuring at least one PRS frequency layer based on Mode 2. According to this method, the total measurement time of the terminal device for measuring at least one PRS frequency layer in Mode 2 can be reduced.

[0114] The embodiments provided in this application will be described in detail below with reference to the drawings.

[0115] Figure 1 is a diagram of a communication method 100 according to one embodiment of this application. As shown in Figure 1, the method 100 may include the following steps.

[0116] 110: The terminal device determines the time to measure each of the Q PRS frequency layers in mode 2.

[0117] Q is a positive integer.

[0118] Optionally, the time of the terminal device for measuring the second PRS frequency layer among the Q PRS frequency layers may be determined based on the first time and / or the second time.

[0119] The second PRS frequency layer is one of the Q PRS frequency layers.

[0120] The first time is the sampling time for measuring the second PRS frequency layer.

[0121] The second time is the measurement time for measuring the last sampling point of the second PRS frequency layer.

[0122] For example, the time for the terminal device to measure the second PRS frequency layer in mode 2 satisfies equation (1). That is,

number

number

[0123] T meas,i This is the time of the terminal device for measuring the second PRS layer, L available_PRS,i This is the first time, T last,iis the second time, and M is a factor that amplifies the measurement time of the second PRS layer due to other factors, such as the beam sweeping factor used when the terminal device performs millimeter-wave frequency measurement using multiple receiving beams. The factor by which the second measurement time is amplified due to other factors is not limited in this application.

Number

[0124] It should be understood that the terminal device may determine the time for measuring the second PRS frequency layer in mode 2 based on equations (1) and (2), or may determine the time for measuring a PRS frequency layer other than the second PRS frequency layer in mode 2 based on equations (1) and (2).

[0125] 120: The terminal device determines the second measurement time based on the maximum value of the time for measuring each of the Q PRS frequency layers.

[0126] For example, the terminal device determines that the second measurement time satisfies equation (3).

number

[0127] The i-th PRS frequency layer is one of the Q PRS frequency layers, meaning that the i-th PRS frequency layer may also be the second PRS frequency layer.

[0128] Based on the aforementioned technical solution, the terminal device may determine the time to measure each of the Q PRS frequency layers in mode 2, and then determine a second measurement time based on the maximum time for measuring each of the Q PRS frequency layers. This method reduces the total measurement time of the terminal device for measuring at least one PRS frequency layer in mode 2.

[0129] Based on step 110, the terminal device may determine the first time in one of several possible ways.

[0130] In a possible manner, the first time is the duration of the PRS resource, the duration of the PRS resource lies within the first window, the length of the first window is the difference between the length of the second measurement time window of the second PRS frequency layer and T2, and the start position of the first window is the start point of the length of the second measurement time window.

[0131] T2 is the processing time capability of the terminal device for measuring the second PRS frequency layer.

[0132] As shown in Figure 2, the length of the first window is the difference between the length of the second measurement time window of the second PRS frequency layer and T2, and the duration of the PRS resource falls within the first window. It can be understood that the duration of the PRS resource may be the entire length of the first window or a part of the length of the first window.

[0133] The second measurement time window may occur periodically, and the second measurement time window in one period may be shown as an instance of the second measurement time window, and the second measurement time window in multiple periods may be shown as multiple instances of the second measurement time window. available_PRS,i or T PRS,i If there are multiple instances of the second measurement time window within the first time, then the first time is T available_PRS,i or T PRS,i The duration of the PRS resource is within the first window of multiple instances of the second measurement time window. In other words, the first time is one T available_PRS,i or T PRS,i This is the duration of the PRS resource within the time window. When the first time is calculated, only the PRS resources within the first window are considered. For example, when the first time is calculated, only the PRS resources for the first H ms within the second measurement time window are considered, where H is the difference between the length of the second measurement time window and T2.

[0134] In another possible way, the first time is the minimum value between the duration of the PRS resource and N2, the duration of the PRS resource is within the first window, the length of the first window is the difference between the length of the second measurement time window of the second PRS frequency layer and T2, and the start position of the first window is the start point of the length of the second measurement time window.

[0135] The first time being the minimum value between the duration of the PRS resource and N2 may be understood as the first time being the duration of the PRS resource, and the duration of the PRS resource being less than or equal to N2.

[0136] T2 is the processing time capability of the terminal device for measuring the second PRS frequency layer, and N2 is the duration capability of the terminal device for measuring the second PRS frequency layer.

[0137] As shown in Figure 2, the length of the first window is the difference between the length of the second measurement time window of the second PRS frequency layer and T2, and the duration of the PRS resource falls within the first window. It can be understood that the duration of the PRS resource may be the entire length of the first window or a portion of the length of the first window. In this case, the first time is the minimum value between the duration of the PRS resource and N2. For example, when the duration of the PRS resource is greater than N2, the first time is N2. In another example, when the duration of the PRS resource is less than N2, the first time is the duration of the PRS resource. In yet another example, when the duration of the PRS resource is equal to N2, the first time may be N2 or the duration of the PRS resource.

[0138] In another possible method, assuming that the length of the second measurement time window is denoted as L, as shown in Figure 3, the length of the second measurement time window L is:

number

[0139] T2 is the processing time capability of the terminal device for measuring the second PRS frequency layer, and N2 is the duration capability of the terminal device for measuring the second PRS frequency layer.

[0140] Based on the aforementioned technical solution, a sampling time for measuring the second PRS frequency layer is defined in Mode 2, allowing sufficient processing time for measuring the second PRS frequency layer to be reserved within the second measurement time window, ensuring that the terminal device can complete processing within the second measurement time window. In this way, the measurement delay is further reduced.

[0141] Based on step 110, the terminal device may determine the second time in one of several possible ways.

[0142] In a possible configuration, the second time is the length of the second measurement time window of the second PRS frequency layer, when all PRS resources of the second PRS frequency layer are within the second measurement time window of the second PRS frequency layer.

[0143] It should be understood that one or more PRS resources may exist in the bandwidth range in which the second PRS frequency layer is located. This is not limited to this embodiment of the application.

[0144] For example, suppose there are six PRS resources in the bandwidth range where the second PRS frequency layer is located. When all six PRS resources are within the second measurement time window, the second time is the length of the second measurement time window.

[0145] In another possible approach, the second time is the available period of the second PRS frequency layer when the PRS resources of the second PRS frequency layer are not within the second measurement time window of the second PRS frequency layer.

[0146] For example, suppose there are six PRS resources in the bandwidth range where the second PRS frequency layer is located. The second time is the available period of the second PRS frequency layer when two PRS resources are not within the second measurement time window.

[0147] Optionally, the terminal device may determine the time to measure each of the P PRS frequency layers in mode 1.

[0148] For the formulas for calculating the time of the terminal device to measure each of the P PRS frequency layers in Mode 1, see Equations (1), (2), and existing solutions. Further details will not be explained again here.

[0149] Optionally, the terminal device determines a first measurement time based on the sum of the times it takes to measure all P PRS frequency layers, where P is a positive integer.

[0150] For example, the terminal device determines that the first measurement time satisfies equation (4).

number

[0151] The first PRS frequency layer is one of P PRS frequency layers, and the i-th PRS frequency layer is one of P PRS frequency layers; that is, the i-th PRS frequency layer may be the first PRS frequency layer.

[0152] Optionally, the terminal device determines a third measurement time based on the first and second measurement times.

[0153] The third measurement time is the time required to measure P+Q PRS frequency layers.

[0154] For example, a terminal device determines a third measurement time based on a first measurement time, a second measurement time, and a first margin, and the third measurement time is the sum of the first measurement time, the second measurement time, and the first margin.

[0155] The first margin may be the time for conversion between different frequency layers, and the first margin is a number greater than or equal to 0. For example, the first margin may be the time for conversion from the first frequency layer to the second frequency layer. In another example, the first margin may be the time for conversion from the second frequency layer to the first frequency layer. For example, the first margin is max(T effect,i ) is also acceptable.

[0156] In the prior art, the measurement mode of the PRS frequency layer may be either mode 1 or mode 2. However, how the terminal device determines whether the measurement mode of the PRS frequency layer is mode 1 or mode 2 is not currently described in the relevant solutions. For example, how the terminal device determines that the measurement mode of the first PRS frequency layer, as referred to in method 100, is mode 1, or how the terminal device determines that the measurement mode of the second PRS frequency layer is mode 2, is not described in the existing solutions.

[0157] In view of the aforementioned technical challenges, this application provides a communication method. According to this method, a terminal device can determine whether the measurement mode of the PRS frequency layer is mode 1 or mode 2, and can determine the measurement behavior of the terminal device.

[0158] Figure 4 is a diagram of another communication method 400 according to one embodiment of this application. As shown in Figure 4, the method 400 may include the following steps.

[0159] 410: The terminal device reports its capability to the LMF, and the capability is associated with the PRS frequency layer.

[0160] In response, the LMF receives the capabilities reported by the terminal device.

[0161] This ability may include at least one of {N,T} or {N2,T2}.

[0162] N and N2 are the duration capability of the terminal device for measuring the PRS frequency layer, and T and T2 are the processing time capability of the terminal device for measuring the PRS frequency layer.

[0163] For example, according to method 100, a terminal device may report a second capability to the LMF, the second capability being associated with a second PRS frequency layer, the second PRS frequency layer being one of Q PRS frequency layers.

[0164] For example, according to method 100, a terminal device may report a first capability to the LMF, the first capability being associated with a first PRS frequency layer, the first PRS frequency layer being one of P PRS frequency layers.

[0165] The association of capabilities reported to the LMF by a terminal device with PRS frequency layers may be understood as the terminal device reporting capabilities to the LMF for the bandwidth range (e.g., frequency band) in which the PRS frequency layer is located. For example, the terminal device reports a first capability to the LMF for the bandwidth range in which a first PRS frequency layer is located. In another example, the terminal device reports a second capability to the LMF for the bandwidth range in which a second PRS frequency layer is located.

[0166] 420: The terminal device determines the measurement mode of the PRS frequency layer based on the capabilities reported to the LMF.

[0167] For example, according to method 100, the terminal device may determine that the measurement mode of the first PRS frequency layer is mode 1 based on the first capability reported to the LMF.

[0168] For example, the terminal device may determine that the measurement mode of the second PRS frequency layer is mode 2 based on a second capability notified to the LMF.

[0169] According to the aforementioned technical solution, the terminal device may determine whether the measurement mode of the PRS frequency layer is mode 1 or mode 2 based on the capabilities reported to the LMF, thereby enabling the determination of the measurement behavior of the terminal device.

[0170] Based on step 420, the terminal device may determine the measurement mode of the PRS frequency layer in one of the following ways, based on the capabilities reported to the LMF.

[0171] Method #A: When the capability reported to the LMF by the terminal device is {N,T}, the terminal device determines that the measurement mode of the PRS frequency layer is mode 1, or when the capability reported to the LMF by the terminal device is {N2,T2}, the terminal device determines that the measurement mode of the PRS frequency layer is mode 2.

[0172] For example, according to method 100, when the first capability reported to the LMF by the terminal device is {N,T}, the terminal device may determine that the measurement mode of the first PRS frequency layer is mode 1.

[0173] For example, according to method 100, when the second capability reported to the LMF by the terminal device is {N2, T2}, the terminal device may determine that the measurement mode of the second PRS frequency layer is mode 2.

[0174] Method #B: The capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}.

[0175] In response, the LMF receives the capabilities reported by the terminal device, which are {N,T} and {N2,T2}. Based on the reported capabilities, the LMF transmits first instruction information to the terminal device, which indicates that the measurement mode of the PRS frequency layer is mode 1 or mode 2.

[0176] In response to this, the terminal device may receive first instruction information from the LMF and, based on the first instruction information, determine that the measurement mode of the PRS frequency layer is mode 1 or mode 2.

[0177] For example, according to method 100, when the first capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, the terminal device may receive first instruction information from the LMF, the first instruction information indicating that the measurement mode of the first PRS frequency layer is mode 1.

[0178] For example, according to method 100, when the second capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, the terminal device may receive first instruction information from the LMF, the first instruction information indicating that the measurement mode of the second PRS frequency layer is mode 2.

[0179] Method #C: When the capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, the terminal device receives second instruction information from the network device, which indicates the length of the measurement time window for the PRS frequency layer. Based on the second instruction information, the terminal device may determine that the measurement mode for the PRS frequency layer is mode 1 or mode 2.

[0180] For example, when the length of the measurement time window for the PRS frequency layer is greater than or equal to a first threshold, the terminal device determines that the measurement mode for the PRS frequency layer is mode 2, or when the length of the measurement time window for the PRS frequency layer is less than the first threshold, the terminal device determines that the measurement mode for the PRS frequency layer is mode 1.

[0181] The first threshold may be T2 + X1, where X1 is a number greater than or equal to 0, and X1 may be predefined in the protocol. For example, the protocol may predefine that X1 may be the length of one slot. Alternatively, X1 may be N2 or another value. This is not limited to this embodiment of the application.

[0182] For example, according to method 100, when the first capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, the terminal device may receive second instruction information from the network device, the second instruction information indicating the length of the first measurement time window of the first PRS frequency layer. The terminal device determines that the measurement mode of the first PRS frequency layer is mode 1 based on whether the length of the first measurement time window is less than a first threshold.

[0183] For example, according to method 100, when the second capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, the terminal device may receive second instruction information from the network device, which indicates the length of the second measurement time window of the second PRS frequency layer. The terminal device determines that the measurement mode of the second PRS frequency layer is mode 2 based on whether the length of the second measurement time window is greater than or equal to a first threshold.

[0184] According to Method 100, when the terminal device reports both the first and second capabilities to the LMF, it should be understood that the terminal device may determine, in one or a different combination of methods #A to #C, that the measurement mode for the first PRS frequency layer is Mode 1 and the measurement mode for the second PRS frequency layer is Mode 2.

[0185] For example, when the first capability reported to the LMF by the terminal device is {N,T} and the second capability reported to the LMF by the terminal device is {N2,T2}, the terminal device may determine, in scheme #A, that the measurement mode of the first PRS frequency layer is mode 1, and the terminal device may also determine, in scheme #A, that the measurement mode of the second PRS frequency layer is mode 2.

[0186] In another example, when the first capability reported to the LMF by the terminal device is {N,T} and the second capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, the terminal device may determine, using method #A, that the measurement mode for the first PRS frequency layer is mode 1, and the terminal device may determine, using method #B or method #C, that the measurement mode for the second PRS frequency layer is mode 2.

[0187] For example, when the first capabilities reported to the LMF by the terminal device are {N,T} and {N2,T2}, and the second capability reported to the LMF by the terminal device is {N2,T2}, the terminal device may determine that the measurement mode of the first PRS frequency layer is mode 1 using method #B or method #C, or the terminal device may determine that the measurement mode of the second PRS frequency layer is mode 2 using method #A.

[0188] In another example, when the first capability reported to the LMF by the terminal device is {N,T} and {N2,T2}, and the second capability reported to the LMF by the terminal device is {N,T} and {N2,T2}, the terminal device may determine, in scheme #B or scheme #C, that the measurement mode of the first PRS frequency layer is mode 1, and the terminal device may determine, in scheme #B or scheme #C, that the measurement mode of the second PRS frequency layer is mode 2.

[0189] In the prior art, a network device may set the length of the measurement time window for the PRS frequency layer for a terminal device. However, when the length of the measurement time window for the PRS frequency layer set by the network device for a terminal device is small, for example, when the length of the measurement time window for the PRS frequency layer set by the network device for a terminal device is less than a first threshold, the terminal device may not be able to determine that the measurement mode of the PRS frequency layer is mode 2.

[0190] Therefore, the length of the measurement time window for the PRS frequency layer set by the network device for the terminal device may not meet the conditions for low-latency measurement, and the terminal device may not be able to perform low-latency measurement.

[0191] For example, according to Method 400, in Method #A, even if the capability reported to the LMF by the terminal device is {N2, T2}, the terminal device may not be able to perform measurements correctly in Mode 2 when the length of the measurement time window for the PRS frequency layer set by the network device for the terminal device is small.

[0192] For example, according to Method 400, in Method #B, even if the first instruction information transmitted to the terminal device by the LMF indicates that the measurement mode of the PRS frequency layer is mode 2, the terminal device may not be able to perform a measurement correctly in mode 2 when the length of the measurement time window of the PRS frequency layer set by the network device for the terminal device is small. In other words, when the terminal device determines that the measurement mode of the PRS frequency layer is mode 2 based on the first instruction information, the condition for the terminal device to perform a measurement correctly is that the length of the measurement time window set by the network device for the terminal device is greater than or equal to a first threshold.

[0193] In view of the aforementioned technical challenges, this application provides a communication method. According to this method, a network device can set the length of the measurement time window for the PRS frequency layer for a terminal device based on low latency-related information, and the terminal device can perform measurements in mode 2 based on the LMF or the requirements of the terminal device.

[0194] Figure 5 is a diagram of another communication method 500 according to one embodiment of this application. As shown in Figure 5, the method 500 may include the following steps.

[0195] 510: A network device receives third instruction information from the first device, and when the length of the measurement time window of the PRS frequency layer is associated with mode 2, the third instruction information indicates that the length of the measurement time window of the PRS frequency layer is greater than or equal to a second threshold, or the third instruction information indicates a first recommendation, the first recommendation being the length of the measurement time window of the PRS frequency layer excluding the duration of the PRS resource.

[0196] For example, according to method 100, the terminal device transmits a third instruction to the network device, the third instruction indicating that the length of the second measurement time window of the second PRS frequency layer is greater than or equal to a second threshold, or the third instruction indicating a first recommendation, the first recommendation being the length of the second measurement time window of the second PRS frequency layer excluding the duration of the PRS resource.

[0197] For information on how network devices obtain the duration of PRS resources, refer to existing solutions. For example, LMF may use an NRPPa message to send a Measurement Preconfiguration Required message to network devices, which contains relevant information about the duration of PRS resources and allows network devices to obtain the duration of PRS resources. Optionally, the first recommended value may be included in the NRPPa message.

[0198] The first device is a terminal device or LMF.

[0199] The second threshold may be T2 + X2, where X2 is a number greater than or equal to 0, and X2 may be predefined in the protocol, or it may be N2, or it may be another value. The second threshold may be the same as the first threshold, or it may be different from the first threshold. This is not limited to this embodiment of the application.

[0200] The first recommended value may be predefined in the protocol or may be any other value. This is not limited to this embodiment of the application.

[0201] The second threshold and third instruction information may be sent to the network device using the same signaling from the same device, or using different signaling from the same device, or using different signaling from different devices.

[0202] In possible scenarios, the second threshold and third instruction information are sent to the network device using the same signaling from the same device. For example, a terminal device uses the first signaling to send the second threshold and third instruction information to the network device. In another example, the LMF uses the second signaling to send the second threshold and third instruction information to the network device.

[0203] In possible scenarios, the second threshold and third instruction information are transmitted to the network device using different signaling from the same device. For example, a terminal device uses a first signaling to send the second threshold to the network device and a second signaling to send the third instruction information to the network device. In another example, an LMF uses a third signaling to send the second threshold to the network device and a fourth signaling to send the third instruction information to the network device.

[0204] In possible scenarios, the second threshold and third instruction information are transmitted to the network device using different signaling from different devices. For example, a terminal device uses a first signaling to transmit the second threshold to the network device, and the LMF uses a second signaling to transmit the third instruction information to the network device. In another example, the LMF uses a third signaling to transmit the second threshold to the network device, and the terminal device uses a fourth signaling to transmit the third instruction information to the network device.

[0205] 520: The network device determines the length of the measurement time window for the PRS frequency layer based on the third instruction information.

[0206] In a possible configuration, the network device determines that the length of the measurement time window for the PRS frequency layer is greater than or equal to a second threshold when a third indicator indicates that the length of the measurement time window for the PRS frequency layer is associated with mode 2.

[0207] For example, according to method 100, when the third indicator information indicates that the measurement mode of the second PRS frequency layer is mode 2, the network device may determine that the length of the second measurement time window of the second PRS frequency layer is greater than or equal to a second threshold.

[0208] In another possible configuration, when the third instruction information indicates a first recommended value, the network device determines that the length of the measurement time window for the PRS frequency layer is the sum of the first recommended value and the duration of the PRS resource.

[0209] For example, according to method 100, when the third instruction information indicates a first recommended value, the network device may determine that the length of the second measurement time window of the second PRS frequency layer is the sum of the first recommended value and the duration of the PRS resource.

[0210] According to the aforementioned technical solution, the network device may determine the length of the measurement time window for the PRS frequency layer based on third instruction information, and the network device may set the length of the measurement time window for the PRS frequency layer for the terminal device based on low latency-related information, enabling the terminal device to perform measurements in mode 2 based on the LMF or the requirements of the terminal device.

[0211] Optionally, the network device transmits a second instruction to the terminal device, which indicates the length of the measurement time window for the PRS frequency layer.

[0212] For example, according to method 100, a network device transmits a second instruction to a terminal device, the second instruction indicating the length of a first measurement time window of a first PRS frequency layer, and the second instruction indicating the length of a second measurement time window of a second PRS frequency layer. The length of the second measurement time window may be determined by the network device based on the third instruction.

[0213] For an explanation of how the terminal device determines, based on the second instruction information, that the measurement mode of the PRS frequency layer is mode 1 or mode 2, see the explanation in Method 400. Further details will not be explained again here.

[0214] In the prior art, the measurement time window of the PRS frequency layer may be either PPW or MG. However, how the terminal device determines whether the measurement time window of the PRS frequency layer is PPW or MG is not currently described in the relevant solutions. For example, how the terminal device determines whether the first measurement time window of the first PRS frequency layer referred to in Method 100 is PPW or MG, and how the terminal device determines whether the second measurement time window of the second PRS frequency layer is PPW or MG, is not described in the existing solutions.

[0215] In view of the aforementioned technical challenges, this application provides a communication method. According to this method, a terminal device can determine whether the measurement time window of the PRS frequency layer is PPW or MG, determine the measurement behavior of the terminal device, and ensure that the terminal device, network device and LMF have a consistent understanding.

[0216] Figure 6 is a diagram of another communication method 600 according to one embodiment of this application. As shown in Figure 6, the method 600 may include the following steps.

[0217] 610: The terminal device receives a fourth instruction from the network device, which indicates whether the PPW is in an active state, and the PPW is associated with the PRS frequency layer.

[0218] The PRS frequency layer may be comprised of an LMF for terminal devices, and the PPW and MG may be comprised of network devices for terminal devices.

[0219] For example, according to method 100, a terminal device receives a fourth instruction from a network device, the fourth instruction indicates whether a first PPW is in an active state, and the first PPW is associated with a first PRS frequency layer among P PRS frequency layers.

[0220] The association of a first PPW with a first PRS frequency layer can be understood as follows: the first PPW is set within a first bandwidth part (BWP) of a first serving cell, the first BWP includes a first PRS frequency layer, and the first BWP and the first PRS frequency layer have the same subcarrier spacing.

[0221] For example, according to method 100, a terminal device receives a fourth instruction from a network device, the fourth instruction indicates whether a second PPW is in an active state, and the second PPW is associated with the second PRS frequency layer among Q PRS frequency layers.

[0222] The second PPW is associated with the second PRS frequency layer if the second PPW is set within the second BWP of the second serving cell, the second BWP includes the second PRS frequency layer, and the second BWP and the second PRS frequency layer have the same subcarrier spacing.

[0223] 620: The terminal device determines the measurement time window for the PRS frequency layer based on the fourth instruction information.

[0224] For example, according to method 100, the terminal device determines a first measurement time window for the first PRS frequency layer based on the fourth instruction information.

[0225] For example, according to method 100, the terminal device determines a second measurement time window for the second PRS frequency layer based on the fourth instruction information.

[0226] According to the aforementioned technical solution, the terminal device may determine the measurement time window of the PRS frequency layer based on the fourth instruction information, thereby determining the measurement behavior of the terminal device and ensuring that the terminal device, network device, and LMF have a consistent understanding.

[0227] Based on step 620, the terminal device may determine the measurement time window for the PRS frequency layer based on the fourth instruction information in one of the following two possible ways:

[0228] In a possible configuration, when the fourth instruction indicates that PPW is active, the terminal device determines that the measurement time window for the PRS frequency layer is PPW.

[0229] For example, when the fourth instruction indicates that the first PPW is active, the terminal device determines that the first measurement time window of the first PRS frequency layer is the first PPW.

[0230] For example, when the fourth instruction indicates that the second PPW is active, the terminal device determines that the second measurement time window of the second PRS frequency layer is the second PPW.

[0231] In another possible configuration, when the fourth instruction indicates that the PPW is in an inactive state, the terminal device determines that the measurement time window for the PRS frequency layer is MG.

[0232] For example, when the fourth instruction indicates that the first PPW is in an inactive state, the terminal device determines that the first measurement time window of the first PRS frequency layer is the first MG.

[0233] For example, when the fourth instruction indicates that the second PPW is in an inactive state, the terminal device determines that the second measurement time window of the second PRS frequency layer is the second MG.

[0234] It should be understood that PPW and MG may coexist when they are associated with different PRS frequency layers. For example, the first measurement time window of the first PRS frequency layer is the first PPW, and the second measurement time window of the second PRS frequency layer is the second MG. The first PPW and the second MG may coexist.

[0235] Optionally, when the PRS frequency layer does not have an associated PPW, the terminal device determines that the measurement time window for the PRS frequency layer is MG.

[0236] Optionally, when a PPW collides with an MG in the time domain, the terminal device does not measure the PRS frequency layer on the instance of the colliding PPW.

[0237] The PRS frequency layer associated with PPW is different from the PRS frequency layer associated with MG.

[0238] For example, if the period of the PPW set by the network device is 80ms and its time domain start position is 0, and the period of the MG set by the network device is 160ms and its time domain start position is 0, then one PPW will conflict with the MG in the time domain every 160ms. In this case, the terminal device will not measure the PRS frequency layer on instances of the conflicting PPW.

[0239] For example, according to Method 100, assuming that the measurement time window for each of the Q PRS frequency layers is PPW and the measurement time window for each of the P PRS frequency layers is MG, the terminal device may determine the time for measuring each of the Q PRS frequency layers in PPW in Mode 2 and determine a second measurement time based on the maximum time for measuring each of the Q PRS frequency layers. Alternatively, the terminal device may determine the time for measuring each of the P PRS frequency layers in MG in Mode 1 and determine a first measurement time based on the sum of the times for measuring all of the P PRS frequency layers. Based on this, the terminal device may determine a third measurement time based on the first and second measurement times.

[0240] Each of the Q PRS frequency layers has a measurement time window of PPW, in other words, there are Q PPWs for the Q PRS frequency layers, and the same PPW may exist within the Q PPWs, or the Q PPWs may be different from each other. Additionally, each of the P PRS frequency layers has a measurement time window of MG, in other words, there are P MGs for the P PRS frequency layers, and the same MG may exist within the P MGs, or the P MGs may be different from each other.

[0241] For example, according to Method 100, assuming that the measurement time window for each of the Q PRS frequency layers is PPW2 and the measurement time window for each of the P PRS frequency layers is PPW1, the terminal device may determine the time for measuring each of the Q PRS frequency layers in PPW2 in Mode 2 and determine a second measurement time based on the maximum time for measuring each of the Q PRS frequency layers. The terminal device may also determine the time for measuring each of the P PRS frequency layers in PPW1 in Mode 1 and determine a first measurement time based on the sum of the times for measuring all of the P PRS frequency layers. Based on this, the terminal device may determine a third measurement time based on the first measurement time and the second measurement time.

[0242] Each of the Q PRS frequency layers has a measurement time window of PPW2, in other words, there are Q PPW2s for each of the Q PRS frequency layers, and the same PPW may exist within each of the Q PPW2s, or the Q PPW2s may be different from each other. Additionally, each of the P PRS frequency layers has a measurement time window of PPW1, in other words, there are P PPW1s for each of the P PRS frequency layers, and the same PPW may exist within each of the P PPW1s, or the P PPW1s may be different from each other.

[0243] For example, assuming that the measurement time window for each of the M PRS frequency layers is PPW and the measurement time window for each of the N PRS frequency layers is MG, the terminal device may determine the time to measure each of the M PRS frequency layers in PPW in mode 1, and determine measurement time 1 based on the sum of the times to measure all of the M PRS frequency layers. The terminal device may further determine the time to measure each of the N PRS frequency layers in MG in mode 1, and determine measurement time 2 based on the sum of the times to measure all of the N PRS frequency layers. Based on this, the terminal device may determine measurement time 3 based on the sum of measurement time 1 and measurement time 2.

[0244] Each of the M PRS frequency layers has a measurement time window of PPW, in other words, there are M PPWs for the M PRS frequency layers, and the same PPW may exist within Q PPWs, or the M PPWs may be different from each other. Additionally, each of the N PRS frequency layers has a measurement time window of PPW, in other words, there are N PPWs for the N PRS frequency layers, and the same PPW may exist within Q PPWs, or the N PPWs may be different from each other.
