Description

Technical Field

[0001] The present application relates to the field of wireless technology, and in particular, to a measurement method and device. Background Art

[0002] In a mobile cellular network, when a terminal device moves from one cell to another, it needs to switch between cells. Before switching, the terminal device needs to measure the signals of the neighboring cells to determine when to switch. Measurements are usually divided into same-frequency measurements and different-frequency measurements. For different-frequency measurements, a common method is to install two RF receivers in the terminal device to measure the frequency of the current cell and the frequency of the target cell respectively, but this will increase costs and cause interference between different frequencies. Therefore, the 3rd Generation Partnership Project (3GPP) proposed the measurement gap (MG) method, which is to reserve a part of time (MG time). During this time, the UE will not send or receive any data, but will tune the receiver to the frequency of the target cell to perform different-frequency measurements, and then switch to the current cell when the MG time ends.

[0003] Extended reality (XR) service is a multimedia service with strong real-time performance and large data capacity requirements, and has strict latency requirements. However, the data arrival period of XR is non-integer, which is difficult to match with the MG period. As a result, the transmission of XR service data will conflict with MG, making it difficult to ensure the reliability of XR service. Therefore, it is urgent to provide a method to solve the conflict problem between XR data transmission and MG. Summary of the invention

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

[0052] In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0053] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0054] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0055] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0056] In the present application, "at least one (item)" refers to one or more. "Multiple" refers to two or more. "At least two (items)" refers to two or three and more than three. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships can exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and / or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple. “When” and “if” both mean that corresponding measures will be taken under certain objective circumstances. It does not limit the time, nor does it require any judgment when it is implemented, nor does it mean that there are other limitations.

[0057] In the present application, "sending information to...(terminal)" can be understood as the destination of the information being the terminal device. It can include sending information to the terminal device directly or indirectly. "Receiving information from...(terminal)" can be understood as the source of the information being the terminal device, which can include receiving information from the terminal device directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly and will not be repeated here.

[0058] Figure 1 Schematic diagram of a communication system applicable to the embodiment of the present application. Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (such as 110a and 110b, collectively referred to as 110) and at least one terminal device (such as 120a-120j, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices ( Figure 1 The terminal device 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices, or can be the same physical device that integrates the core network logical function and the radio access network logical function.

[0059] RAN 100 may be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, or a future-oriented evolution system (such as a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), CRAN, or WiFi system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0060] The RAN node 110, which may also be sometimes referred to as a network device, an access network device, a RAN entity or an access node, etc., constitutes a part of a communication system to help terminal devices achieve wireless access. The multiple RAN nodes 110 in the communication system may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal device 120 are relative. For example, the network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b may be understood as communication devices with base station functions, and the network elements 120a-120j may be understood as communication devices with terminal functions.

[0061] In one possible scenario, the RAN node may be a BS, an eNodeB, an access point (AP), a TRP, a gNB, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The RAN node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example), a relay node or a donor node, or a wireless controller in a CRAN scenario.

[0062] Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the V2X technology may be an RS. All or part of the functions of the RAN node in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in this application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0063] In another possible scenario, multiple RAN nodes collaborate to assist the terminal device in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0064] In different communication systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0065] It should be understood that the number of each device in the above-mentioned communication system is only for illustration and is not limited thereto. In actual applications, the communication system may further include more terminal devices, more RAN devices, and may further include other devices. The network device in the embodiment of the present application may be a device for communicating with a terminal device, and the network device may be a base transceiver station (BTS) in a GSM system or CDMA, or a base station (nodeB, NB) in a WCDMA system, or an evolved base station (evolutional node B, eNB or enodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, etc. For example, the network device may include an access network device, and / or a core network device.

[0066] The terminal device involved in the embodiment of the present application is a device with wireless transceiver function, which can be a fixed device or a mobile device, and can refer to user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a public land mobile communication network (PLMN) to be evolved in the future. The terminal device can also be a handheld device (such as a mobile phone), a wearable device, a vehicle-mounted device, or a wireless device built into the above device (for example, a communication module, a modem, or a chip system, etc.). The terminal device is used to connect people, objects, machines, etc., and can be widely used in various scenarios, such as but not limited to the following scenarios: cellular communication, device to device communication (D2D), vehicle to everything (V2X), machine to machine / machine type communication (M2M / MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, drone, robot and other scenarios. The embodiments of the present application are not limited to this.

[0067] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) system or new radio (NR), 5.5G, sixth generation (6G) system or future communication system, etc.

[0068] Figure 2 This is an example of a configuration of a measurement gap in the prior art. Figure 2 As shown in the figure, the length of a radio frame corresponding to a system frame number (SFN) can be 10 milliseconds (ms), and a radio frame can contain 10 radio subframes (SF), and the length of a subframe can be 1ms. In the time domain corresponding to the shaded area in the figure, the UE can perform heterofrequency measurements on the target cell. During this period, the terminal device will not send or receive any data. The duration of the terminal device suspending communication with the serving cell to measure heterofrequency neighbors or other radio access technology (RAT) neighbors is called the measurement gap MG. After the MG time ends, it switches to the current cell.

[0069] The starting position of the MG time can satisfy the following formulas (1) to (2):

[0070]

[0071] SF=GO%10(2)

[0072] Among them, % is the modulus, MGRP is the measurement gap repetition period (MGRP), which specifies the gap period, that is, the length of the interval from the start time of the current MG time to the start time of the next MG time; the value of MGRP can be 20ms, 40ms, 80ms, 160ms, etc.

[0073] GO is the gap offset of the gap pattern, and the value range can be 0 to 159, and can be an integer, with a total of 160 offset values. The offset value points to the starting subframe in the period, and its value range is from 0 to MGRP-1. For example, if the period is 20ms, the offset range can be 0 to 19.

[0074] The radio frame number SFN to which the start time of the MG belongs can satisfy the above formula (1), and the starting subframe number of the start time of the MG in the SFN can satisfy the above formula (2). For example, when the MGRP is 40ms and the GO is 24ms, the SFN configured by the MG may include 18, 22, 26, 30, etc., and the starting subframe number in each SFN may be 4. When the measurement gap length (MGL) is 4ms, the MG can be configured to perform inter-frequency cell measurements for 4ms starting from 4ms, that is, Figure 2 The example shown. The MGL is the duration of the MG, and the value can include 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms and 6ms, etc. For example, when the MGL is 4ms, the terminal device continues to perform inter-frequency measurements in the same measurement cycle, and the measurement duration is 4ms. For positioning measurements, 10 and 20ms can also be applicable.

[0075] In XR services, since the XR data arrival period is non-integer, for example, for XR video with a frame rate of 60 frames per second (FPS), the frame arrival period is 1 / 30s, that is, 60 video frames are generated per second, and a video frame appears approximately every 16.67ms. The XR frame arrival period can also be 1 / 30s, 1 / 90s, etc. The XR service arrival period cannot match the MG period, so the XR service data transmission will conflict with the MG, such as Figure 3As shown. For XR video with a frame rate of 60FPS, when mode 0 is used, that is, when MGL is 6ms and MGRP is 40ms, the transmission of 2 frames out of every 6 frames is affected. XR services have high latency requirements and require mobility or positioning measurements, and MG has a greater impact on service performance. Therefore, it is necessary to provide a method to reduce the conflict between service data transmission and MG and improve service reliability.

[0076] For ease of understanding and explanation, the following describes the method of the embodiment of the present application by taking the interaction between the terminal device and the network device as an example, but this should not constitute any limitation on the execution subject of the method of the embodiment of the present application. For example, the method performed by the terminal device can also be performed by a module of the terminal (such as a circuit, a chip, or a chip system, etc.), and can also be implemented by a logical node, a logical module, or software that can realize all or part of the functions of the terminal device. The method performed by the network device can also be performed by a module of the network device (such as a circuit, a chip, or a chip system, etc.), and can also be implemented by a logical node, a logical module, or software that can realize all or part of the functions of the network device.

[0077] Figure 4 A method for configuring an MG is provided in an embodiment of the present application. The method may include the following steps S401 to S402.

[0078] S401, the terminal device receives first configuration information, and accordingly, the network device sends first configuration information, the first configuration information including first information and second information, the first information is used to indicate the length of each first measurement gap in at least two first measurement gaps, the at least two first measurement gaps are located in a first measurement cycle, and there is a gap in the time domain between two adjacent first measurement gaps in at least two first measurement gaps, and the second information is used to indicate the start time of each first measurement gap in the at least two first measurement gaps.

[0079] S402: The terminal device performs inter-frequency measurement in at least two first measurement gaps.

[0080] For step S401, the first configuration information may be configured by the network device and sent to the terminal device. For example, the network device may carry the first configuration information in a radio resource control (RRC) message and send it to the terminal device.

[0081] The second information is used to indicate the start time of each first measurement gap in at least two first measurement gaps. The start time of each first measurement gap can be directly configured for the network device, or parameters related to the start time of each first measurement gap can be provided to the network device so that the terminal device can indirectly determine the start time of each first measurement gap based on the parameter. The configuration method of each first measurement gap is described in detail below in combination with the specific implementation method.

[0082] In a possible implementation, the second information may include a first parameter, and the first parameter may be used to indicate the interval length between two adjacent first measurement gaps in at least two first measurement gaps, that is, the interval length between the end time of the current first measurement gap and the start time of the next first measurement gap. In each of the at least two first measurement gaps, the terminal device measures the inter-frequency cell, and during the interval between the two adjacent first measurement gaps, the terminal device can normally send and receive data.

[0083] The first parameter may also be referred to as the measurement gap gap (MGG), or may have other names, which are not limited in the present application. The first parameter may be a numerical value, and when the first parameter is a numerical value, in at least two first measurement gaps, the interval lengths between any two adjacent first measurement gaps are the same. The first parameter may also be a numerical list, and when the first parameter is a numerical list, in at least two first measurement gaps, the interval lengths between two adjacent first measurement gaps may be different, and the network device may specify the interval lengths between all adjacent first measurement gaps in the first measurement cycle through the first parameter. Among them, the different interval lengths between two adjacent first measurement gaps may mean that the interval between at least one group of adjacent first measurement gaps is different from the intervals between the remaining groups of adjacent first measurement gaps.

[0084] In at least two first measurement gaps of the first measurement cycle, the start time of the first first measurement gap may be determined first, and then the start times of the remaining first measurement gaps may be determined.

[0085] In some embodiments, the second information may also include a first offset and a length of a first measurement cycle. The first offset may be an offset of a first first measurement gap in a first measurement cycle. The first offset may be used to determine a start time of a first first measurement gap among at least two first measurement gaps. The start time of the first first measurement gap may satisfy the aforementioned formulas (1) to (2), wherein GO in the formula may be the first offset, and MGRP may be the length of the first measurement cycle.

[0086] Further, the start time of the remaining first measurement gaps except the first first measurement gap in the at least two first measurement gaps may be determined according to the start time of the first first measurement gap, the lengths of the at least two first measurement gaps, and the first parameter.

[0087] As an example, in at least two first measurement gaps, the interval lengths between two adjacent first measurement gaps may be different, and the interval lengths between two adjacent first measurement gaps may be configured to the terminal device in the form of a numerical list, and the numerical list of the first parameter may be as shown in Table 1. When the first parameter is a numerical list, the numerical list of the first parameter may include the interval lengths between any two adjacent first measurement gaps in at least two first measurement gaps, and further, the number of first measurement gaps may be the number of interval lengths configured by the network device plus 1. For the example shown in Table 1, the number of interval lengths configured by the network device is 2, then the first measurement cycle may include 3 first measurement gaps MG1 to MG3, and MG1 to MG3 may be configured in chronological order. MGG1 may be the interval length between MG1 and MG2, that is, the time interval from the end time of MG1 to the start time of MG2. Similarly, MGG2 may be the interval length between MG2 and MG3.

[0088] Table 1

[0089] MGG[i] Length / ms MGG1 6 MGG2 3

[0090] Table 2

[0091] MGL[i] Length / ms MGL1 2 MGL2 2 MGL3 1.5

[0092] The lengths of each first measurement gap may also be different. The network device may provide the lengths of the first measurement gaps to the terminal device in the form of a numerical list. The length list of the first measurement gaps may be as shown in Table 2. The numerical list of the first parameter may include the length of each first measurement gap in at least two first measurement gaps. Among them, MGL1 may be the length of the first first measurement gap MG1 in the first measurement cycle, MGL2 may be the length of the second first measurement gap MG2 in the first measurement cycle, and MGL3 may be the length of the third first measurement gap MG3 in the first measurement cycle. Similarly, when the first parameter is a numerical list, the number of first measurement gaps is the same as the number of first gap lengths configured by the network device, and the number of first measurement gap lengths configured by the network device for the terminal device may match the number of intervals of the first measurement gaps.

[0093] Furthermore, when the GO configured for the network device is 14ms and the MGRP is 20ms, SFN can be a value such as 22 or 24, and the starting subframe number SF can be 4. Taking the wireless frame with SFN=22 as an example, the starting time of MG1 can be the 5th subframe in the wireless frame with SFN=22. Furthermore, the starting time of MG2 can be the (2+6)th subframe after the starting time of MG1, that is, the 3rd subframe in SFN=23. Similarly, the starting time of MG3 can be the (2+3)th subframe after the starting time of MG2, that is, the 8th subframe in SFN=23. Thus, the terminal device can determine that the measurement mode of MG is Figure 5 In the mode shown, the terminal device performs cell measurement in the shaded area shown in the figure.

[0094] As another example, in at least two first measurement gaps, the interval length between any two adjacent first measurement gaps may also be the same, and the first parameter may be a numerical value, for example, 2.5 ms, that is, in at least two first measurement gaps, the interval length between any two adjacent first measurement gaps may be 2.5 ms.

[0095] The length of each of the at least two first measurement gaps may also be the same, that is, the first information may also include a value, such as 1.5 ms, to indicate that the length of each of the at least two first measurement gaps may be 1.5 ms.

[0096] The start time of MG1 can satisfy the above formulas (1) to (2). When GO is 14 ms and MGRP can be 20 ms, the start time of MG1 can be the 5th subframe in SFN=22. Then, the start time of MG2 can be the (1.5+2.5)th subframe after the start time of MG1, that is, the 9th subframe in SFN=22. By analogy, we can get Figure 6 The measurement gap configuration mode is shown.

[0097] It should be noted that Figure 5 In the example shown, in at least two first measurement gaps, the intervals between two adjacent first measurement gaps are different, and the lengths of at least two first measurement gaps are also different. Figure 6 In the example shown, the interval between any two adjacent first measurement gaps is the same, and the lengths of at least two first measurement gaps are also the same. When the interval between any two adjacent first measurement gaps is the same, the lengths of at least two first measurement gaps can also be configured to be different. When the lengths of at least two first measurement gaps are the same, the lengths between any two adjacent first measurement gaps can also be configured to be different. This application does not limit this.

[0098] In some embodiments, the first configuration information can also be used to configure the number of first measurement gaps in the first measurement period, that is, the number of inter-frequency measurements performed by the terminal device in the first measurement period can be configured. For example, when the lengths of at least two first measurement gaps are the same and the intervals between any two adjacent first measurement gaps are the same, the number of first measurement gaps can be configured by the network device, such as Figure 6 In the configuration mode shown, the number of first measurement gaps can be configured by the network device to be 4. For another example, when the lengths of at least two first measurement gaps are different, a length list is configured for the terminal device to indicate the lengths of each first measurement gap, and the configured length list of the first measurement gaps can be used to indicate the number of first measurement gaps, that is, the number of first measurement gaps can be carried in the first information, or the number of first measurement gaps can be directly indicated by the first configuration information. Similarly, when the intervals between two adjacent first measurement gaps are different, an interval length list can be configured for the terminal device to indicate the interval length between each group of two adjacent first measurement gaps, and the configured interval length list between two adjacent first measurement gaps can be used to indicate the number of first gaps, that is, the number of first measurement gaps can be carried in the second information, or the number of first measurement gaps can be directly indicated by the first configuration information.

[0099] The number of the first measurement gaps may be less than or equal to L is the total length of at least two first measurement gaps, so as to reduce the overlap problem between the measurement time configured in the first measurement cycle and the measurement time configured in other cycles.

[0100] When the first parameter is a value, in a possible implementation, the first parameter may be a value enumerated by the network device. Exemplarily, the value of the first parameter enumerated by the network device may be 3ms, 5ms, 6ms, 7ms, 10ms, 11ms, 13ms, 14ms, 20ms, 22ms, 26ms, 29ms, 40ms, 45ms, 53ms, 106ms, etc., and the first parameter may be an integer or a decimal value, such as 2.5ms, 5.5ms, etc.

[0101] In another possible implementation, the first parameter may be any value within a value range of 0 to MGRP provided by the network device.

[0102] In some embodiments, the range of the first parameter MGG may satisfy the following conditions: in, is a floor rounding function, L may be the sum of the lengths of at least two first measurement gaps in the first measurement period, and N is the length of the first measurement gap in the first measurement period.

[0103] The range of the first parameter MGG The overlap of the first measurement gaps configured in each measurement cycle can be reduced, or in other words, the problem of at least two first measurement gaps in the current measurement cycle being arranged in the time domain in the next measurement cycle and overlapping with the first measurement gap in the next measurement cycle can be reduced.

[0104] In some embodiments, the first parameter may be an agreed value between the network device and the terminal device. In this example, the network device may not need to carry the above-mentioned second information in the first configuration information. For example, in step S401, the first configuration information may only include the first information, and the terminal device may store the agreed value in advance. When receiving the first configuration information, the start time of at least two first measurement gaps is determined according to the stored first parameter, and heterofrequency measurements are performed on at least two first measurement gaps according to the start time of the at least two first measurement gaps and the length of the at least two first measurement gaps. When the first parameter is an agreed value between the network device and the terminal device, in at least two first measurement gaps, the interval length between any two first measurement gaps may be the same.

[0105] In some embodiments, the length of at least two first measurement gaps may also be an agreed value between the network device and the terminal device. In this example, the network device may not need to carry the above-mentioned first information in the first configuration information. For example, in step S401, the first configuration information may only include the second information, and the terminal device may store the agreed value in advance. When receiving the first configuration information, the start time of at least two first measurement gaps is determined according to the first parameter provided by the network device, and heterofrequency measurements are performed on at least two first measurement gaps according to the start time of the at least two first measurement gaps and the length of the at least two first measurement gaps. When the length of the at least two first measurement gaps is an agreed value between the network device and the terminal device, the lengths of any two first measurement gaps in the at least two first measurement gaps may be the same.

[0106] In some embodiments, the first parameter and the length of at least two first measurement gaps can be agreed values ​​between the network device and the terminal device. In this example, the network device may not need to carry the first information and the second information in the first configuration information, and the terminal device and the network device may not need to perform step S401. The terminal device can determine the start time of at least two first measurement gaps based on the stored first parameter, and perform heterofrequency measurements on at least two first measurement gaps based on the start time of the at least two first measurement gaps and the length of at least two first measurement gaps. Similarly, when the first parameter and the length of at least two first measurement gaps are agreed values, in at least two first measurement gaps, the length of any two first measurement gaps can be the same, and in at least two first measurement gaps, the interval length between any two first measurement gaps can be the same.

[0107] The method for configuring measurement gaps provided in the embodiment of the present application can configure sparsely distributed measurement gaps in a measurement cycle. When the terminal device has data to send, it can send it in the nearest time slot that is not configured with the first measurement gap, thereby reducing the time conflict problem between the data transmission and reception service and the measurement gap, while also ensuring the performance of the low-latency service.

[0108] In addition, since the data transmission period of the XR service is a non-integer and cannot match the MG measurement period, the method for configuring the measurement gap in this embodiment can also match the XR period. Figure 7 As shown, for an XR service with a period of 50 / 3, that is, an XR service with a frame rate of 60FPS, the length of the first measurement period can be 50ms, the value of the first parameter can be 17-MGL', MGL' is the length of each first measurement gap in at least two first measurement gaps, the length of each first measurement gap in at least two first measurement gaps can be the same, the value of the first offset can be 0, and the number of first measurement gaps in the first measurement period can be 3. Thus, the data transmission period of the XR service and the MG measurement period can be matched, and the measurement time can be offset relative to the XR data transmission time, and the offset time can be greater than or equal to the data transmission delay of the XR service, so that the terminal device can perform gap measurement after the XR data arrives, that is, after the XR data transmission is completed, so as to better ensure the reliability of the XR service, and also ensure the performance of the cell measurement.

[0109] In a possible implementation, the second information may include a second parameter, and the second parameter may be used to indicate the interval length between the remaining first measurement gaps except the first first measurement gap and the first first measurement gap in the at least two first measurement gaps in the first measurement cycle. The interval length between the remaining first measurement gaps except the first first measurement gap and the first first measurement gap may refer to the interval length between the start time of the remaining first measurement gaps except the first first measurement gap and the start time of the first first measurement gap in the at least two first measurement gaps; or, it may also refer to the interval length between the end time of the remaining first measurement gaps except the first first measurement gap and the end time of the first first measurement gap; or, it may also refer to the interval length between the middle moments of the remaining first measurement gaps except the first first measurement gap and the middle moment of the first first measurement gap, and the interval lengths between the middle moments of the remaining first measurement gaps and the middle moment of the first first measurement gap and the start time of the first measurement gap may be the same.

[0110] In some embodiments, the second information may further include a first offset and a length of a first measurement period, where the first offset may be an offset of a first first measurement gap in at least two first measurement gaps in the first measurement gap, and the start time of at least two first measurement gaps may satisfy the following formulas (3) to (4):

[0111]

[0112] SF[i]= (GO + GOO[i]) % 10, (4)

[0113] SFN[i] may be the radio frame number to which the start time of the i-th first measurement gap in the first measurement cycle belongs, SF[i] is the starting subframe number of the start time of the i-th first measurement gap in the corresponding radio frame, GO is the first offset, GOO[i] is the interval length between the i-th first measurement gap and the first first measurement gap, i may be an integer greater than or equal to 1, and MGRP is the length of the first measurement cycle. When i is 1, GOO[1] may be the interval length between the first first measurement gap and the first first measurement gap, that is, the value of GOO[1] may be 0.

[0114] In some embodiments, the second parameter may be in the form of a numerical list, and the numerical list may include the interval length between each first measurement gap and the first first measurement gap in the remaining first measurement gaps except the first first measurement gap in the first measurement cycle. For example, as shown in Table 3, GOO[2] may be the interval length between the second first measurement gap and the first measurement gap in the first measurement cycle, GOO[3] may be the interval length between the third first measurement gap and the first measurement gap in the first measurement cycle, and so on. When the second parameter is in the form of a numerical list, the second information may also be used to indicate the number of first measurement gaps in the first measurement cycle. For example, if the value of GOO[i] shown in Table 3 is 3, the number of first measurement gaps in the first measurement cycle may be 4. In the numerical list of the second parameter shown in Table 3, the interval lengths between each first measurement gap in the first measurement cycle and the first first measurement gap are in an arithmetic progression. In this example, the intervals between the start times of two adjacent first measurement gaps may be the same.

[0115] The start time of each first measurement gap in the first measurement period satisfies the above formulas (3) to (4). Furthermore, when the first offset GO is 14ms and the length of the first measurement period is 20ms, the subframe number corresponding to the start time of the first measurement gap may be 4, that is, it may be the 5th subframe in SFN=22, the subframe number corresponding to the start time of the second measurement gap may be 8, that is, it may be the 9th subframe in SFN=22, the subframe number corresponding to the start time of the third measurement gap may be 1, that is, it may be the 2nd subframe in SFN=23, and the subframe number corresponding to the start time of the fourth measurement gap may be 5, that is, it may be the 6th subframe in SFN=23. When the lengths of any two first measurement gaps in at least two first measurement gaps are the same, for example, they may be 1.5ms, the measurement gap mode of the terminal device may be as follows: Figure 8 As shown in (b) of FIG. 1 , the terminal device can perform inter-frequency measurement in the shaded area of ​​the figure. Figure 8 (a) is the MG configuration mode in the prior art. The measurement method provided in the embodiment of the present application makes the measurement time in the first measurement cycle dispersed so that the terminal device can send on the nearest time slot that is not configured with the first measurement gap, thereby ensuring the reliability of the service and the performance of the heterofrequency measurement.

[0116] Table 3

[0117] GOO[i] Length / ms GOO[2] 4 GOO[3] 8 GOO[4] 12

[0118] It should be noted that, similar to when the second information includes the first parameter above, when the second information includes the second parameter, the lengths of at least two first measurement gaps may be the same or different. When the lengths of at least two first measurement gaps are different, the first information may include a list of lengths of the first measurement gaps, indicating the length of each first measurement gap in the first measurement period. Here, the same length of at least two first measurement gaps is used as an example to introduce the mode of the measurement gap, and the lengths of at least two first measurement gaps should not be limited. The terminal device may also agree with the network device on the length value of the first measurement gap. In this case, the network device may not need to carry the lengths of at least two first measurement gaps in the first configuration information. In addition, in the numerical list of the second parameter shown in Table 3, the interval lengths between each first measurement gap in the first measurement period and the first first measurement gap are in an arithmetic progression, and the interval lengths between each first measurement gap and the first first measurement gap may also be discrete values, that is, they may not be in an arithmetic progression. When the interval lengths between each first measurement gap and the first first measurement gap are discrete values, the intervals between the start times of two adjacent first measurement gaps may be different.

[0119] In the example where the second information includes the second parameter, the measurement method may also be matched to the XR cycle. Fig. 9 As shown, for an XR service with a period of 50 / 3, that is, an XR service with a frame rate of 60FPS, the value of the first offset can be 0, and the corresponding starting subframe number can be 0, that is, in the first measurement period, the starting subframe of the first first measurement gap can be the first subframe in the corresponding radio frame, the length of the first measurement period can be 50ms, and 3 first measurement gaps can be configured in the first measurement period to match the XR service. The second parameter can be a value list, and the value of GOO[2] can be 17ms, and the value of GOO[3] can be 34ms, so that the data transmission period of the XR service and the MG measurement period can be matched, and the measurement time can be offset relative to the XR data transmission time. The terminal device can perform gap measurement after the XR data arrives, that is, after the XR data transmission is completed, so as to better ensure the reliability of the XR service and the performance of the cell measurement.

[0120] In a possible implementation, the second information may further include a third parameter, which may be used to indicate the start time of each first measurement gap in at least two first measurement gaps, and the third parameter may be a measurement gap offset of each first measurement gap in the at least two first measurement gaps in the first measurement cycle.

[0121] The third parameter may be in the form of a numerical list, and the numerical list may include the offset of each of the at least two first measurement gaps in the first measurement cycle, and the offsets of the first measurement gaps may be different. Exemplarily, the numerical list of the third parameter may be as shown in Table 4, wherein, in the first measurement cycle, the offset of the first first measurement gap may be 24ms, the offset of the second measurement gap may be 28ms, the offset of the third measurement gap may be 32ms, and the offset of the fourth measurement gap may be 36ms. When the third parameter is in the form of a numerical list, the second information may also be used to indicate the number of first measurement gaps in the first measurement cycle. For example, for the third parameter example shown in Table 4, the number of first measurement gaps may be 4. The offsets of the first measurement gaps shown in Table 4 are in an arithmetic progression. When the lengths of at least two first measurement gaps are the same, the interval lengths between two adjacent first measurement gaps in the first measurement cycle may be the same.

[0122] Table 4

[0123] GO[i] Value / ms GO[1] 14 GO[2] 18 GO[3] 12 GO[4] 16

[0124] In this implementation, the second information may also include the length of the first measurement period MGRP. The start time of at least two first measurement gaps in the first measurement period may satisfy the following equations (5) to (6):

[0125]

[0126] SF[i] = GO[i] % 10 (6)

[0127] Among them, SFN[i] is the wireless frame number to which the i-th first measurement gap belongs in at least two first measurement gaps, SF[i] is the starting subframe number of the i-th first measurement gap in the wireless frame to which it belongs, GO[i] is the offset of the i-th first measurement gap, that is, the third parameter, and i can be an integer greater than or equal to 1.

[0128] Exemplarily, when the length of the first measurement period is 20 ms, and the offset of each first measurement gap in the first measurement period is as shown in Table 4, the subframe number corresponding to the start time of the first first measurement gap may be 4, that is, it may be the 5th subframe in SFN=22, the subframe number corresponding to the start time of the second first measurement gap may be 8, that is, it may be the 9th subframe in SFN=22, the subframe number corresponding to the start time of the third first measurement gap may be 2, that is, it may be the 3rd subframe in SFN=23, and the subframe number corresponding to the start time of the fourth first measurement gap may be 6, that is, it may be the 7th subframe in SFN=23. When the lengths of any two first measurement gaps in at least two first measurement gaps are the same, for example, 1.5 ms, the measurement gap pattern in the first measurement period may be as follows: Fig.10 As shown in (b), where Fig.10 (a) is the MG configuration mode in the prior art. The measurement method provided in the embodiment of the present application makes the measurement time in the first measurement cycle dispersed so that the terminal device can send on the nearest time slot that is not configured with the first measurement gap, thereby ensuring the reliability of the service and the performance of the heterofrequency measurement.

[0129] It should be noted that, similar to when the second information includes the first parameter above, when the second information includes the third parameter, the lengths of at least two first measurement gaps may be the same or different. When the lengths of at least two first measurement gaps are different, the first information may include a list of first measurement gap lengths, indicating the length of each first measurement gap in the first measurement cycle. Here, the measurement gap mode is introduced by taking the same length of at least two first measurement gaps as an example, and the lengths of at least two first measurement gaps should not be limited.

[0130] In the example where the second information includes the third parameter, the measurement method can also be matched to the XR cycle. Fig.11 As shown, for an XR service with a period of 50 / 3, that is, an XR service with a frame rate of 60FPS, the length of the first measurement period can be 50ms, the first measurement period can include 3 first measurement gaps, and the offset value of the first first measurement gap in the first measurement period can be 0, the offset value of the second first measurement gap can be 17, and the offset value of the third first measurement gap can be 34, so that the data transmission period of the XR service and the MG measurement period can be matched, and the measurement time can be offset relative to the XR data transmission time. The terminal device can perform gap measurement after the XR data arrives, that is, after the XR data transmission is completed, so as to better ensure the reliability of the XR service and also ensure the performance of the cell measurement.

[0131] In a possible implementation manner, the second information may further include a fourth parameter, and the fourth parameter may be used to indicate the length of an interval between start times of two adjacent first measurement gaps in the at least two first measurement gaps.

[0132] In some embodiments, the second information may further include the first offset and the length of the first measurement period.

[0133] As an example, in at least two first measurement gaps, when the intervals between the start times of two adjacent first measurement gaps are different, the start times of the at least two first measurement gaps may satisfy the following formulas (7) to (8):

[0134]

[0135] SF[i] = (GO + G[i]) % 10, (8)

[0136] Wherein, SFN[i] is the radio frame number to which the i-th first measurement gap in at least two first measurement gaps belongs, SF[i] is the starting subframe number of the i-th first measurement gap in the radio frame to which it belongs, and G[i] is the fourth parameter, and may be the interval length between the start time of the i-th first measurement gap in the first measurement cycle and the start time of the i-1-th first measurement gap. In this example, the second parameter may be in the form of a numerical list.

[0137] As another example, in at least two first measurement gaps, the interval between the start times of two adjacent first measurement gaps may be the same, and the start times of at least two first measurement gaps may satisfy (9) to (10):

[0138]

[0139] SF[i]= (GO + GOO[i]) % 10, (10)

[0140] SFN[i] is the radio frame number to which the i-th first measurement gap in at least two first measurement gaps belongs, SF[i] is the starting subframe number of the i-th first measurement gap in the radio frame to which it belongs, G is the fourth parameter, and may be the interval length between the start times of any two adjacent first measurement gaps in the first measurement cycle, and i may be an integer greater than or equal to 1. In this example, the second parameter may be a numerical value.

[0141] When the second information includes the fourth parameter, the lengths of the at least two first measurement gaps may be the same or different.

[0142] In some embodiments, the duration of each first measurement gap in the at least two first measurement gaps may be greater than or equal to 1.5 ms to ensure the switching time of the measurement gaps and improve the reliability of inter-frequency measurement.

[0143] The measurement method described in the above embodiment configures at least two first measurement gaps in the first measurement cycle, and there is an interval in the time domain between two adjacent first measurement gaps in the at least two first measurement gaps, so that multiple first measurement gaps in the first measurement cycle are dispersedly distributed to reduce the conflict between the measurement time and the service data transmission time. The first measurement cycle may also include only one measurement gap, or a second measurement gap, and the conflict between the measurement time and the service data transmission time is reduced by regulating the start time of the second measurement gap. The method can be as follows Fig.12 The method may include steps S1201 to S1202.

[0144] S1201, the terminal device receives second configuration information, and accordingly, the network device sends second configuration information, the second configuration information including third information and fourth information, the third information is used to indicate the length of at least two measurement cycles, each of the at least two measurement cycles includes a second measurement gap, and the fourth information is used to indicate the start time of the second measurement gap in each measurement cycle in the at least two measurement cycles, and the start time of the second measurement gap in each measurement cycle matches the service data transmission cycle of the terminal device.

[0145] S1202: The terminal device performs inter-frequency measurement in a second measurement gap in each measurement cycle in at least two measurement cycles.

[0146] For step S1201, the third information may include a measurement period list (MGRP-list), which may include the length of each measurement period in at least two measurement periods, and the lengths of at least two measurement periods may be the same or different. For example, for an XR service with a period of 50 / 3, that is, an XR service with a frame rate of 60FPS, the lengths of at least two measurement periods may both be 50ms to match the XR service with a frame rate of 60FPS; for another example, the lengths of at least two measurement periods may also be values ​​such as 50ms, 100ms, and 150ms, respectively. The number of second measurement gaps included in each of the at least two measurement periods may be one, and by configuring the start time of the second measurement gap in each measurement period, the second measurement gap in each measurement period may be offset from the transmission time of the XR service data.

[0147] As an example, the fourth information may include a fifth parameter, which may be used to indicate the interval length between the second measurement gaps of two adjacent measurement cycles in at least two measurement cycles, and the fifth parameter may be recorded as M1. Fig.13 As shown, for an XR service with a frame rate of 60FPS, the length of at least two measurement cycles can be 50ms, and three second measurement gaps can be configured in each 50ms cycle, and the three second measurement gaps can be measurement gaps in three adjacent measurement cycles. For example, MG1 can be the second measurement gap of the first measurement cycle in multiple measurement cycles, MG2 can be the second measurement gap of the second measurement cycle in multiple measurement cycles, MG3 can be the second measurement gap of the third measurement cycle in multiple measurement cycles, and so on. MG1, MG2 and MG3 can be located in the same 50ms cycle, that is, the start time of MG1 to the start time of MG4 can be the first measurement cycle, and the length of the measurement cycle MGRP1 is 50ms. The start time of MG2 and MG3 can be configured so that the measurement time of MG2 and MG3 can be located in the time domain of the first measurement cycle. For example, the value of M1 can be 17-MGL', MGL' is the length of each second measurement gap in at least two measurement cycles, and the length of the second measurement gap in each measurement cycle can be the same. In this way, the MG measurement period can match the data transmission period of the XR service, and the measurement time can be offset from the XR service data transmission time. The offset time can ensure that the data transmission of the terminal device is completed. The terminal device can perform gap measurement after the XR data transmission is completed, thereby better ensuring the reliability of the XR service and the performance of the cell measurement.

[0148] As another example, the fourth information may include a sixth parameter, which may be used to indicate the interval length between the second measurement gap in the remaining measurement cycles except the first measurement cycle and the second measurement gap in the first measurement cycle in at least two measurement cycles. In at least two measurement cycles, the interval length between the second measurement gap in the remaining measurement cycles except the first measurement cycle and the second measurement gap in the first measurement cycle may be the interval length between the start time of the second measurement gap in the remaining measurement cycles except the first measurement cycle and the start time of the second measurement gap in the first measurement cycle, or the interval length between the end time of the second measurement gap in the remaining measurement cycles except the first measurement cycle and the end time of the second measurement gap in the first measurement cycle, or the interval length between the middle moment of the second measurement gap in the remaining measurement cycles except the first measurement cycle and the middle moment of the second measurement gap in the first measurement cycle, and the interval length between the middle moments of the two and the start time of the second measurement gap to which they belong may be the same. The sixth parameter may be recorded as M2[i], that is, the interval length between the second measurement gap of the i-th measurement cycle and the second measurement gap of the first measurement cycle in at least two measurement cycles. As Fig.14 As shown, for the XR service with a frame rate of 60FPS, the length of at least two measurement cycles can be 50ms. Taking the start time of the second measurement gap in at least two measurement cycles as an example, the interval length M2[2] between the start time of the second measurement gap of the second measurement cycle and the start time of the second measurement gap of the first measurement cycle can be 17, and the interval length M2[3] between the start time of the second measurement gap of the third measurement cycle and the start time of the second measurement gap of the first measurement cycle can be 34, so that 3 second measurement gaps can be configured in a period of 50ms, so that the MG measurement cycle can match the data transmission cycle of the XR service, and the measurement time can have an offset with the XR service data transmission time. The offset time can ensure that the data transmission of the terminal device is completed. The terminal device can perform gap measurement after the XR data transmission is completed, thereby better ensuring the reliability of the XR service and also ensuring the performance of the cell measurement.

[0149] As another example, the fourth information may further include a seventh parameter, which may be used to indicate an offset value of a second measurement gap of each measurement cycle in at least two measurement cycles, and the seventh parameter may be recorded as M3[i], that is, an offset value of a second measurement gap of an i-th measurement cycle in at least two measurement cycles. Fig.15As shown, the offset value M3[1] of the second measurement gap of the first measurement cycle in at least two measurement cycles can be 0, the offset value M3[2] of the second measurement cycle of the second measurement cycle can be 17, and the offset value M3[3] of the second measurement cycle of the third measurement cycle can be 34, so that the MG measurement cycle can match the data transmission cycle of the XR service, and the measurement time can have an offset with the XR service data transmission time. The offset time can ensure that the data transmission of the terminal device is completed. The terminal device can perform gap measurement after the XR data transmission is completed, thereby better ensuring the reliability of the XR service, while also ensuring the performance of the cell measurement.

[0150] Fig.12 In the described embodiment, the second configuration information may include third information to indicate the length of at least two measurement cycles, and the second configuration information may include fourth information to indicate the start time of the second measurement gap in each measurement cycle. The network device may also send the length of at least two measurement cycles to the terminal device through different configuration information. For example, the second configuration information may be used to indicate the length of one measurement cycle in at least two measurement cycles, and the lengths of other measurement cycles in at least two measurement cycles may be sent to the terminal device through the third configuration information. Similarly, the network device may also configure the start time of the second measurement gap of each measurement cycle in at least two measurement cycles to the terminal device through different configuration information. For example, the network device may carry the start time of one measurement cycle in at least two measurement cycles in the second configuration information, such as carrying the offset of the second measurement gap in the measurement cycle, and the offsets of the second measurements in the remaining measurement cycles may be sent to the terminal device through the third configuration information.

[0151] The number of second measurement gaps included in each measurement cycle of at least two measurement cycles may also be multiple. When each measurement cycle includes a second measurement gap, the configuration method of the start time of the multiple second measurement gaps in each measurement cycle may be the same as Figure 5 to Figure 11 The described embodiments are similar and will not be described again here to avoid repetition.
