[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on September 27, 2023, with application number 202311288677.5 and application name "A Measurement Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a measurement method and device. Background Art

[0004] In communication systems, to ensure service continuity and communication quality for terminal devices, terminal devices typically need to perform cell measurements to enable cell reselection and handover. Cell measurements can be performed on the same frequency or on different frequencies or systems.

[0005] When the terminal device initially accesses or performs inter-frequency / inter-system measurements during the radio resource control (RRC) connection state (RRC_connective), in order to ensure the quality of the radio link between the terminal device and the current serving cell, the terminal device usually stops receiving the signal and data of its serving cell during a specified time period, and receives signals from other cells to perform inter-frequency measurements or inter-system measurements. When the time period ends, the terminal device starts receiving the signal and data of the serving cell again. This time period is called a measurement gap (MG). During the measurement gap, the terminal device receives the reference signal of the neighboring cell and measures the reference signal of the neighboring cell. After the measurement is completed, the terminal device sends a measurement report to the network device that manages the serving cell. The network device then switches the terminal device to a cell with better signal quality based on the measurement report.

[0006] The R18 standard of the 3rd Generation Partnership Project (3GPP) agreed that for heterogeneous system measurements, terminal devices are allowed to perform measurements even when not in the measurement gap. For example, in scenarios where there is a spare RF link that can be used to measure evolved universal terrestrial radio access (E-UTRA) measurement objects (MO), or where the activated bandwidth part (BWP) can fully cover the E-UTRA MO that needs to be measured, a terminal device whose serving cell is a new radio (NR) cell can also measure the E-UTRA MO without in the measurement gap. However, not measuring the E-UTRA MO in the measurement gap may cause the terminal device to restrict the scheduling of the network device, that is, the terminal device cannot normally perform the uplink and downlink data scheduling of the network device. Therefore, the standard further introduces a measurement window, which defines a time domain position for the terminal device to perform measurements of the E-UTRA MO that will generate scheduling restrictions.

[0007] However, after the introduction of the measurement window, the network equipment and terminal equipment have an unclear understanding of whether to indicate (or configure) the measurement window and measurement gap. It is unclear when to use what time domain position to measure which MO, which may easily cause inconsistent understanding between the terminal equipment and the network equipment, and may affect communication performance.

[0008] Summary of the Invention

[0009] The embodiments of the present application provide a measurement method and device to clarify the understanding of network equipment and terminal equipment on whether to indicate (or configure) measurement windows and measurement gaps, reduce the duration of terminal equipment scheduling interruptions due to measurements, and improve communication performance.

[0010] In a first aspect, an embodiment of the present application provides a measurement method, the method comprising: a terminal device receives first information from a network device; when the first information indicates a measurement gap and does not indicate a measurement window, the terminal device measures a first E-UTRA MO according to the measurement gap, and the first E-UTRA MO is an E-UTRA MO with scheduling restrictions and does not require a measurement gap to perform measurement; when the first information does not indicate a measurement gap and does not indicate a measurement window, the terminal device does not measure the first E-UTRA MO.

[0011] Through the above method, the network device can, when the terminal device has scheduling restrictions and does not require the first E-UTRA MO (i.e., long term evolution (LTE) MO) to perform measurements, only indicate (or configure) the measurement gap, so that the terminal device measures the first E-UTRA MO according to the measurement gap; or not indicate (or configure) the measurement gap and measurement window, indirectly / implicitly indicate not to measure the first E-UTRA MO, which can reduce the duration of the terminal device's scheduling interruption due to measurement, clarify the understanding of the terminal device and the network device on whether to indicate (or configure) the measurement window and measurement gap, and is conducive to improving the communication performance between the terminal device and the network device.

[0012] In one possible design, before the terminal device receives the first information from the network device, the method also includes: the terminal device sends second information to the network device, the second information indicating that the terminal device supports performing E-UTRA measurements without measurement gaps when the E-UTRA cell reference signal (CRS) is completely contained by a bandwidth part (BWP) activated by the terminal device, wherein the first E-UTRA MO is completely contained by the BWP; or, the second information indicates that the first E-UTRA frequency band does not require measurement gaps to perform E-UTRA measurements, and the first E-UTRA MO corresponds to the first E-UTRA band.

[0013] The above design is helpful for the network device to obtain information about whether the terminal device needs a measurement gap to perform measurements on the first E-UTRA MO.

[0014] In one possible design, the measurement gap indicated by the first information is determined based on a new radio (NR) MO or a second E-UTRA MO configured by the network device for the terminal device that requires measurement gaps to perform measurements.

[0015] Through the above design, the network device can indicate (or configure) the measurement gap according to the NR MO or the second E-UTRA MO configured for the terminal device that requires measurement gaps to perform measurements, and be compatible with the measurements of the NR MO or the second E-UTRA MO that requires measurement gaps to perform measurements.

[0016] In the second aspect, an embodiment of the present application provides a measurement method, which includes: a terminal device receives third information from a network device, the third information indicates a measurement gap and a measurement window, wherein the measurement gap corresponds to at least one first measurement opportunity, and the measurement window corresponds to at least one second measurement opportunity; in the event of a conflict between the first target measurement opportunity and the second target measurement opportunity, the terminal device measures the MO according to one or more of the priorities of the measurement gap and the measurement window, the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window, and the measurement gap ratio coefficient of each type of MO, wherein the first target measurement opportunity belongs to at least one first measurement opportunity, and the second target measurement opportunity belongs to at least one second measurement opportunity.

[0017] Through the above method, the terminal device can support one or more of the priorities of the measurement gap and the measurement window, the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window, and the measurement gap ratio coefficient of each type of MO to resolve the conflict between the measurement gap and the measurement window.

[0018] In one possible design, when the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device measures the MO according to the priorities of the measurement gap and the measurement window, including: when the priority of the measurement gap is greater than or equal to the priority of the measurement window, the terminal device measures the MO according to the first target measurement opportunity; when the priority of the measurement gap is less than the priority of the measurement window, the terminal device measures the MO according to the second target measurement opportunity. Optionally, the method further includes: the terminal device receives fourth information from the network device, the fourth information being used to indicate the priority of the measurement gap and / or the priority of the measurement window.

[0019] The above method provides a solution for MO measurement based on priority when measurement timings of a measurement gap and a measurement window conflict.

[0020] In one possible design, when the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device measures the MO according to the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window, including: when the number of first measurement opportunities corresponding to the measurement gap is greater than or equal to the number of second measurement opportunities corresponding to the measurement window, the terminal device measures the MO according to the second target measurement opportunity; when the number of first measurement opportunities corresponding to the measurement gap is less than the number of second measurement opportunities corresponding to the measurement window, the terminal device measures the MO according to the first target measurement opportunity.

[0021] Through the above method, a solution for MO measurement is provided according to the number of measurement opportunities when the measurement opportunities of the measurement gap and the measurement window conflict. In addition, the measurement gap or measurement window with a smaller number of measurement opportunities is given priority, which is conducive to taking into account the measurement requirements of the terminal device for measuring MO in the measurement gap and measurement window.

[0022] In one possible design, when the first target measurement timing conflicts with the second target measurement timing, the terminal device measures the MO according to the measurement gap proportion coefficient of each type of MO, including: the terminal device measures the target type of MO at the first target measurement timing, wherein the target type of MO is determined according to the first measurement gap proportion coefficient of the same-frequency MO, the second measurement gap proportion coefficient of the different-frequency MO or the different-system MO other than the E-UTRA MO with scheduling restrictions, and the third measurement gap proportion coefficient of the E-UTRA MO with scheduling restrictions.

[0023] The above method provides a solution for MO measurement when the measurement gap and the measurement window have conflicting measurement timings based on the measurement gap ratio of each type of MO.

[0024] In one possible design, the first measurement gap proportion coefficient is X, the second measurement gap proportion coefficient is 100-XY, and the third measurement gap proportion coefficient is Y, where X and Y are natural numbers, and X+Y is less than or equal to 100; or, the first measurement gap proportion coefficient is X, the second measurement gap proportion coefficient is (100-X)*Q%, and the third measurement gap proportion coefficient is (100-X)*(100-Q)%, where X and Q are natural numbers less than or equal to 100.

[0025] In a third aspect, an embodiment of the present application provides a measurement method, the method comprising: a network device configures a first E-UTRA MO for a terminal device, the first E-UTRA MO being an E-UTRA MO with scheduling restrictions and which does not require a measurement gap to perform measurement; the network device sends first information to the terminal device, the first information indicating a measurement gap but not indicating a measurement window, or the first information does not indicate a measurement gap and does not indicate a measurement window.

[0026] In one possible design, before the network device configures the first E-UTRA MO for the terminal device, the method further includes: the network device receives second information from the terminal device, the second information indicating that the terminal device supports performing E-UTRA measurements without measurement gaps when the E-UTRA CRS is completely contained by the BWP activated by the terminal device, wherein the first E-UTRA MO is completely contained by the BWP; or, the second information indicates that the first E-UTRA band does not require measurement gaps to perform E-UTRA measurements, and the first E-UTRA MO corresponds to the first E-UTRA band.

[0027] In one possible design, the measurement gap indicated by the first information is determined based on a new wireless NR MO or a second E-UTRA MO configured by the network device for the terminal device that requires a measurement gap to perform measurements.

[0028] In a fourth aspect, an embodiment of the present application provides a measurement method, which includes: a network device sends third information to a terminal device, the third information indicating a measurement gap and a measurement window, wherein the measurement gap corresponds to at least one first measurement opportunity, the measurement window corresponds to at least one second measurement opportunity, and the at least one first measurement opportunity does not conflict with the at least one second measurement opportunity.

[0029] In one possible design, when the measurement window period of the measurement window is an integer multiple of the measurement timing configuration SMTC period based on the synchronization signal / physical broadcast channel block SSB, the measurement window offset of the measurement window satisfies: (n-1)*smtc_periodicity+smtc_offset+smtc_duration≤window_offset≤n*smtc_periodicity+smtc_offset-window_duration; when the SMTC period is an integer multiple of the measurement window period, the measurement window offset of the measurement window satisfies: (n-1)*window_periodicity+window_offset+window_duration≤sm tc_offset≤n*window_periodicity+window_offset-smtc_duration; wherein window_offset represents the measurement window offset, smtc_offset represents the SMTC offset, window_duration represents the window duration of the measurement window, smtc_periodicity represents the SMTC period, smtc_duration represents the SMTC duration, and window_periodicity represents the measurement window period. n=0, 1, 2, ..., and the measurement gap is determined according to smtc_offset, smtc_periodicity, and smtc_duration.

[0050] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, also known as E-TURA system, evolved LTE (LTE-advanced, LTE-A) system, universal mobile telecommunications system (UMTS), and fifth generation (5G) mobile communication systems such as NR, beyond 5G (B5G) mobile communication systems, or sixth generation (6G) and other communication systems evolved after 5G. The communication system can also be a device-to-device (D2D) network, a machine-to-machine (M2M) network, an Internet of Things (IoT) network, or other networks.

[0051] The architecture of the communication system used in the embodiments of the present application can be shown in Figure 1. Communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, communication system 1000 may also include the Internet 300. RAN 100 includes at least one network device (such as 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal device (such as 120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal device 120 is wirelessly connected to network device 110. Network device 110 is wirelessly or wiredly connected to core network 200. The core network devices in core network 200 and network device 110 in RAN 100 may be different physical devices, or they may be the same physical device that integrates core network logical functions and radio access network logical functions.

[0052] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a 4G, 5G, or an evolved system beyond 5G (e.g., a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN) or a cloud radio access network (CRAN). The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0053] The apparatus provided in the embodiment of the present application can be applied to the network device 110 or to the terminal device 120. It is understood that FIG1 only shows a possible communication system architecture to which the embodiment of the present application can be applied, and in other possible scenarios, the communication system architecture may also include other devices.

[0054] The network device 110 is a node in the radio access network (RAN), which can also be called an access network device or a RAN node (or device). The network device 110 is used to help terminal devices achieve wireless access. The multiple network devices 110 in the communication system 1000 can be nodes of the same type or different types. In some scenarios, the roles of the network device 110 and the terminal device 120 are relative. For example, the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured as a mobile base station. For 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 network device 110 and the terminal device 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and the network elements 120a-120j can be understood as communication devices with terminal device functions.

[0055] In one possible scenario, a network device may be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, a mobile switching center, or a network device in a non-terrestrial network (NTN) communication system, i.e., it may be deployed on a high-altitude platform or satellite. The network device may be a macro base station (such as 110a in Figure 1 ), a micro base station or an indoor station (such as 110b in Figure 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. The network device may also be a device that functions as a base station in device-to-device (D2D) communication, Internet of Vehicles (IoV) communication, drone communication, or machine communication. Optionally, the network device may be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0056] In another possible scenario, multiple network devices collaborate to assist the terminal device in achieving wireless access, and different network devices respectively implement part of the functions of the base station. For example, the network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It can be understood that the network device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into a network device in the access network RAN, or the CU can be divided into a network device in the core network CN, which is not limited here.

[0057] In different 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, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0058] In the embodiments of the present application, the form of the network device is not limited. The device used to implement the function of the network device can be a network device; it can also be a device that can support the network device to implement the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device.

[0059] The terminal device 120, which may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device used to provide voice or data connectivity to users, or an IoT device. For example, the terminal device includes a handheld device with wireless connection capabilities, an in-vehicle device, etc. Currently, terminal devices can include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices (such as smart watches, smart bracelets, pedometers, etc.), vehicle-mounted devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, smart point-of-sale (POS) machines, customer-premises equipment (CPE), wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and flying devices (such as intelligent robots, hot air balloons, drones, airplanes). Terminal devices can also be other devices with terminal functions, for example, terminal devices can also be devices that function as terminals in D2D communication.

[0060] The embodiments of this application do not limit the device form factor of the terminal device. The device used to implement the functions of the terminal device can be the terminal device; it can also be a device that supports the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of a chip or include a chip and other discrete components.

[0061] To facilitate understanding by those skilled in the art, some terms in this application are explained below.

[0062] 1) Neighboring cell measurement, also known as neighboring area measurement. To ensure service continuity in communication systems, terminal devices can switch or reselect between cells with different coverage areas to ensure uninterrupted wireless network service. For example, when a terminal device moves to the edge of a cell, the network equipment will issue measurement control tasks, such as on-frequency, off-frequency, or inter-system, to enable the terminal device to switch to a neighboring cell on the same frequency, off-frequency, or inter-system basis.

[0063] Among them, there are many scenarios for cell switching or reselection. For example, in scenario 1, after the terminal device accesses the service cell, the location of the terminal device moves. For example, when it is far away from the service cell, the terminal device can perform cell switching or cell reselection. In scenario 2, when the service quality of the service cell currently providing services to the terminal device is poor (for example, the signal strength is low), the terminal device can perform cell switching or cell reselection to access a neighboring cell with a better signal. The service cell here is the cell that currently provides services to the terminal device, and the neighboring cell can be understood as other cells other than the service cell that the terminal device can search for in the service cell.

[0064] For example, when the terminal device is in the RRC connection (RRC_connected) state, there is an RRC link between the terminal device and the serving cell. The serving cell can send measurement configuration information to the terminal device through RRC signaling, etc., instructing the terminal device to perform neighboring cell measurements. The terminal device can report the measurement results of the neighboring cell to the serving cell, and the serving cell switches the terminal device to a cell with better signal quality based on the measurement results. When the terminal device is in the RRC_connected state, the process of switching from the serving cell to the neighboring cell is a cell handover process. It can be understood that the above-mentioned cell reselection or cell handover process is based on the measurement results of the neighboring cell.

[0065] For another example, when the terminal device is in the radio resource control (RRC) idle (RRC_idle) state and the RRC inactive (RRC_inactive state), there is no RRC link between the terminal device and the serving cell. When the signal quality of the serving cell where the terminal device resides is lower than a certain threshold, the serving cell can send measurement configuration information to the terminal device, instructing the terminal device to perform neighboring cell measurements to measure the signal quality of the neighboring cell. If the signal quality meets the conditions, the terminal device switches to the neighboring cell and resides in the neighboring cell. When the terminal device is in the RRC_idle state and the RRC_inactive state, the process of switching from the serving cell to other cells is the cell reselection process.

[0066] 2) Reference Signals: Terminal devices can perform cell search and measurement using reference signals sent by network equipment. In 4G networks (such as LTE), network equipment continuously transmits cell reference signals (CRS), which are evenly distributed across every subframe. This makes it easy for terminal devices to measure the signal quality of neighboring cells. They only need to determine the carrier frequency of the reference signal to be measured, and measurements can be performed at any time domain location.

[0067] To reduce overhead and reference signal interference from other cells, 5G (such as NR) networks remove CRS and introduce synchronization signal / physical broadcast channel block (SS / PBCH block, SSB) for cell signal measurement. The synchronization block consists of synchronization signal (synchronization signal, SS) and physical broadcast channel (physical broadcast channel, PBCH), and its transmission period is longer than CRS.

[0068] As shown in Figure 2, SSB is sent periodically, and multiple SSBs can be sent within a period. Multiple SSBs can be concentrated in a certain time window within the period to form an SSB block set (burst set / burst). The SSB period can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms, and the SSB period of different NR cells can also be different. For example, assuming the SSB period is 20ms, the SSB block set can be concentrated in the first or second 5ms to be sent.

[0069] 3) Measurement configuration information is sent by the network device to the terminal device, and is used to enable the terminal device to perform cell measurement according to the measurement configuration information. Generally, the network device can send the measurement configuration information through RRC signaling (such as RRC reconfiguration (RRCReconfiguration) message, etc.). The measurement configuration information may include one or more of the following measurement parameters: measurement objects (MO), measurement gap (MG) configuration parameters, measurement report reporting configurations, measurement report triggering quantity (triggering quantity), measurement identities (measurement identities), i.e., measurement ID.

[0070] 4) SSB-based measurement timing configuration (SMTC), the NR cell will periodically send multiple SSB beams in the time domain (i.e., SSB beam scanning), and the SSB beam of each cell will be configured with the same frequency domain position in the frequency domain. In order to ensure accurate and complete measurement of the SSB beam under the cell, when the network device sends the measurement configuration information, in addition to indicating the SSB frequency point to be measured, it will also indicate the timing position and duration for starting the SSB measurement, thereby introducing a new concept SMTC. The configuration of SMTC can effectively indicate the time window for the terminal device to search for SSB, reducing unnecessary measurement power consumption of the terminal device. SMTC indicates that when the terminal device performs SSB-based measurement on a certain cell, the timing configuration sent by the network device to the terminal device includes the SMTC period, SMTC duration, and SMTC offset (also called SMTC bias).

[0071] 5) Measurement object: The measurement object is the object on which the terminal device performs measurement, which may include the measurement object of NR (MeasObjectNR), the measurement object of evolved universal terrestrial radio access (E-UTRA) (MeasObjectEUTRA), etc.

[0072] MeasObjectEUTRA is the MO of E-UTRA (that is, LTE). MeasObjectEUTRA contains measurement-related information about the E-UTRA (that is, LTE) cell, such as the frequency of the reference signal of the E-UTRA cell (that is, LTE), such as the carrier frequency (carrierFreq) of the reference signal, the maximum allowed measurement bandwidth (allowedMeasBandwidth) on the carrier, etc.

[0073] MeasObjectNR is the NR MO. MeasObjectNR contains measurement-related information about the NR cell, such as the NR cell's SSB information, such as the SSB frequency, SSB subcarrier spacing, and SSB-based measurement timing configuration (SMTC) configuration. Due to the different definitions of measurement objects between NR and LTE, the concepts of NR co-frequency measurement and inter-frequency measurement have also changed compared to E-UTRA: SSB-based co-frequency measurement: The SSB frequency used for measurement in the neighboring cell is the same as the SSB frequency of the serving cell, and the SSB subcarrier spacing is the same; SSB-based inter-frequency measurement: The SSB frequency used for measurement in the neighboring cell is different from the SSB frequency of the serving cell, or the two have the same SSB frequency but different SSB subcarrier spacing.

[0074] It can be understood that in the embodiment of the present application, the MO of E-UTRA (i.e., the MO of LTE) can also be called E-UTRA MO or LTE MO, and the MO of NR can also be called NR MO.

[0075] In addition, it is worth noting that the terms E-UTRA, LTE, and 4G can be used interchangeably in any position in this application.

[0076] 6) Measurement Gaps (MGs): When a terminal device's receiver bandwidth is insufficient to cover both the serving cell's and the neighboring cell's frequencies, the terminal device will measure the neighboring cell with a certain measurement gap. Currently, for inter-frequency or inter-system (i.e., different radio access technologies (inter-RAT)) scenarios, terminal devices generally require measurement gaps to perform effective measurements.

[0077] Co-frequency measurement: The measurement and data reception frequencies do not conflict. The terminal device is always listening to the primary carrier, so the terminal device can perform the measurement without any adjustments. In particular, measurement gaps are required when the terminal device's currently active BWP does not cover the MO to be measured.

[0078] Inter-frequency or inter-system measurements: If the terminal device does not have multiple receivers, or the terminal device's receiver bandwidth does not cover the inter-frequency or inter-system frequency to be measured, it cannot simultaneously transmit and receive signals in the serving cell and measure neighboring cells. In this case, the serving cell needs to arrange some measurement gaps for the terminal device to perform inter-frequency or inter-system measurements.

[0079] The measurement gap can be pre-configured or configured by the network device. The measurement gap is a time period during which the terminal device performs measurements, and no uplink or downlink transmission is scheduled during the measurement gap. Information about the measurement gap pre-configured or configured by the network device may include: a measurement gap repetition period (MGRP), a measurement gap length (MGL), a measurement gap offset (gapOffset) used to configure the starting position of the measurement gap, and a measurement gap timing advance (MGTA). If MGTA is configured, the terminal device must start measurement MGTA ahead of the measurement gap subframe.

[0080] Under normal circumstances, the relationship between the measurement GAP and SMTC configuration can be shown in Figure 3, where D represents the downlink time slot, U represents the uplink time slot, and S represents the flexible time slot or special time slot. The key to the measurement gap configuration is to ensure that during measurement, the effective measurement duration after deducting the frequency switching time at the beginning and end of the measurement gap can completely cover the SMTC duration of the frequency point, so as to ensure that the heterodyne frequency point can be fully measured.

[0081] 7) Effective measurement window (EMW): 3GPP's R18 standard agrees that for inter-system measurements, terminal devices can perform measurements without measurement gaps, and defines three types of inter-system measurements that do not require measurement gaps, including: Case a-1: Inter-system NR measurement without measurement gaps because there is an idle RF link for terminal device measurement; Case b-1: Inter-system E-UTRA measurement without measurement gaps because there is an idle RF link for terminal device measurement; Case b-2: Inter-system E-UTRA measurement without gaps when the E-UTRA CRS to be measured (that is, the E-UTRA MO to be measured) is completely contained in the activated BWP of the terminal device. At the same time, the R18 standard also clarifies that when the NR terminal device performs such E-UTRA (that is, LTE) measurements, no measurement gaps or interruptions are required.

[0082] However, when the E-UTRA MO is not measured within the measurement gap, the following problem will arise: the terminal device's measurement of the E-UTRA MO (such as the E-UTRA CRS) will restrict the NR scheduling, that is, the terminal device cannot perform uplink and downlink data scheduling normally. Therefore, the standard further introduces the concept of an effective measurement window, which can also be called a measurement window or an effective measurement timing configuration (EMTC). The time domain location defined by the measurement window is used for the terminal device to perform measurements of the E-UTRA MO that will generate scheduling restrictions (or have scheduling restrictions). The measurement window period, measurement window offset, and window duration are defined for the measurement window. The defined measurement window periods include 40ms and 80ms. If this concept is not introduced, the terminal device can measure the E-UTRA MO (such as the E-UTRA CRS) at any location. The network device will not know when the terminal device performs the E-UTRA MO (such as the E-UTRA CRS) measurement and will not be able to accurately schedule NR data, which will affect NR data scheduling.

[0083] However, after the introduction of the measurement window, the network equipment and terminal equipment have an unclear understanding of whether to indicate (or configure) the measurement window and measurement gap. It is unclear when to use what time domain position to measure which MO, which may easily cause inconsistent understanding between the terminal equipment and the network equipment, and may affect communication performance.

[0084] Based on this, embodiments of the present application provide a measurement method and apparatus to clarify the understanding between network devices and terminal devices regarding whether to indicate (or configure) measurement windows and measurement gaps, thereby reducing the duration of scheduling interruptions for terminal devices due to measurement, and improving communication performance. The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0085] Furthermore, it should be understood that ordinal numbers such as "first" and "second" in the embodiments of this application are used to distinguish between multiple objects and are not used to define the size, content, order, timing, priority, or importance of the multiple objects. For example, "first information" and "second information" do not indicate a difference in priority or importance between the two pieces of information.

[0086] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plural" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may 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, 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. For example, A / B means: A or B. "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, or c means: 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.

[0087] The measurement method provided in the embodiments of this application can be performed by a first communication device and a second communication device. The first communication device herein can refer to the terminal device itself, or to a processor, module, chip, or chip system in the terminal device that implements the method. The second communication device can refer to the network device itself, or to a processor, module, chip, or chip system in the network device that implements the method. The following describes the measurement method of this application, taking the first communication device and the second communication device as an example, respectively, representing the terminal device and the network device.

[0088] It is understandable that different embodiments of the present invention may be combined with each other, and a single embodiment may only execute some steps or more steps when executed.

[0089] FIG4 is a schematic diagram of a measurement method provided in an embodiment of the present application, the method comprising:

[0090] S401: The network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information.

[0091] Referring to Table 1, which is a schematic diagram of the relationship between existing MO types and measurement gaps and measurement windows, the first row of Table 1 lists possible MO types, which may include NR MO and E-UTRA MO (i.e., LTE MO). The NR MO may include one or more of: an NR MO that requires measurement gaps to perform measurements (referred to as gap-required NR MO) and an NR MO that does not require measurement gaps to perform measurements (referred to as no-gap NR MO). The E-UTRA MO (i.e., LTE MO) may include one or more of: an E-UTRA MO that requires measurement gaps to perform measurements (referred to as gap-required E-UTRA MO), an E-UTRA MO that has scheduling restrictions and does not require measurement gaps to perform measurements (referred to as no-gap restricted E-UTRA MO), and an E-UTRA MO that does not have scheduling restrictions and does not require measurement gaps to perform measurements (referred to as no-gap unrestricted E-UTRA MO).

[0092] Table 1

[0093] The second row of Table 1 indicates that the network device indicates (or configures) the measurement gap and measurement window for the terminal device. For NR MO and E-UTRA MO that require measurement gaps to perform measurements, the terminal device performs measurements within the measurement gap; for NR MO that does not require measurement gaps to perform measurements, the terminal device can decide at what time domain position to measure based on the time domain position of the SMTC corresponding to the NR MO, that is, measure within the time window of the SSB indicated by the SMTC corresponding to the NR MO (also referred to as measuring within the SMTC); for E-UTRA MO with scheduling restrictions that do not require measurement gaps to perform measurements, the terminal device can perform measurements at the corresponding time domain position according to the measurement window; for E-UTRA MO without scheduling restrictions that do not require measurement gaps to perform measurements, the terminal device can perform measurements at any time domain position.

[0094] The third row of Table 1 indicates that there are no NR MO and E-UTRA MO that require measurement gaps to perform measurements. The network device only indicates (or configures) the measurement window for the terminal device. For NR MO that does not require measurement gaps to perform measurements, the terminal device can decide at what time domain position to perform measurements based on the time domain position of the SMTC corresponding to the NR MO; for E-UTRA MO with scheduling restrictions that does not require measurement gaps to perform measurements, the terminal device can perform measurements at the corresponding time domain position according to the measurement window; for E-UTRA MO that does not have scheduling restrictions and does not require measurement gaps to perform measurements, the terminal device can perform measurements at any time domain position.

[0095] It should be noted that the measurement gap in the embodiment of the present application may also be a network controlled small gap (NCSG) or an interruption, where interruption is a concept introduced by the 3GPP R18 standard. Similar to NCSG, it is a time domain position shorter than the measurement gap. That is to say, in the embodiment of the present application, the need to perform measurement in the measurement gap can also be understood as the need to perform measurement in one or more of the measurement gap, NCSG, and interruption, and the need not to perform measurement in the measurement gap can also be understood as the need not to perform measurement in one or more of the measurement gap, NCSG, and interruption.

[0096] In addition, in some implementations, the measurement gap may also be referred to as a gap. The indication (or configuration) of a measurement gap involved in the embodiments of the present application may also be understood as an indication (or configuration) of the activation / validity of the measurement gap. The activated / validity measurement gap may be pre-configured or configured by the network device to the terminal device. Similarly, the indication (or configuration) of a measurement window may also be understood as an indication (or configuration) of the activation / validity of the measurement window. The activated / validity measurement window may be pre-configured or configured by the network device to the terminal device.

[0097] For MOs with scheduling restrictions (such as NR MOs and E-UTRA MOs), this may be because the sub-carrier space (SCS), beam direction, working mode, working frequency band, etc. of the terminal device's current operation are different from the SCS, beam direction, working mode, working frequency band, etc. required by the MO to be measured. For example, the SCS of the terminal device's serving cell is 30 kHz, and the SCS required by the MO to be measured is 60 kHz; or the terminal device operates in frequency range (FR) 1 (i.e., frequency band below 6 GHz) in time division duplex (TDD) mode, and the MO to be measured requires the terminal device to operate in frequency division duplex (FDD) mode in FR2 (i.e., frequency band above 30 GHz), etc. When measuring the MO, the terminal device cannot continue to send and receive data in the serving cell due to scheduling restrictions.

[0098] S402: When the first information indicates a measurement gap but does not indicate a measurement window, the terminal device measures a first E-UTRA MO according to the measurement gap. The first E-UTRA MO is an E-UTRA MO with scheduling restrictions that does not require a measurement gap to perform measurement.

[0099] S403: When the first information does not indicate a measurement gap and does not indicate a measurement window, the terminal device does not measure the first E-UTRA MO.

[0100] In an embodiment of the present application, the baseline scheme in which the network device indicates (or configures) a measurement window for the terminal device when the MO that the terminal device needs to measure includes an E-UTRA MO (i.e., LTE MO) that has scheduling restrictions and does not require measurement gaps to perform measurements is changed, and the network device indicates (or configures) a measurement window for the terminal device, and the terminal device measures the E-UTRA MO (i.e., LTE MO) that has scheduling restrictions and does not require measurement gaps to perform measurements according to the measurement window is changed to a scheme in which the network device may not indicate (or configure) a measurement window for the terminal device when the MO that the terminal device needs to measure includes an E-UTRA MO (i.e., LTE MO) that has scheduling restrictions and does not require measurement gaps to perform measurements.

[0101] In one possible implementation, when the MO that the terminal device needs to measure includes a first E-UTRA MO that has scheduling restrictions and does not require measurement gaps for measurement, the network device may send first information indicating (or configuring) measurement gaps but not indicating (or configuring) measurement windows to the terminal device. The first information may include measurement configuration information, measurement-related indication information, etc.

[0102] Optionally, the first information may be included in an RRC reconfiguration message. The first information may be sent to the terminal device via one message or multiple messages, which is not limited in this application.

[0103] As an example: if the network device configures the terminal device with an NR MO and / or a second E-UTRA MO that requires a measurement gap to perform measurements, the measurement gap indicated (or configured) by the first information can be determined based on the measurement gap required by the NR MO and / or the second E-UTRA MO. Alternatively, if the terminal device is pre-configured with a measurement gap or the network device has configured a measurement gap for the terminal device, the network device can also activate / validate the measurement gap pre-configured or configured by the network device for the terminal device through the first information. After the terminal device receives the first information, the terminal device can measure the first E-UTRA MO based on the measurement gap indicated (or configured) by the first information. For example: the first E-UTRA MO can be measured within the measurement gap indicated (or configured) by the first information, that is, the first E-UTRA MO can be measured within the time domain position (or time domain range) corresponding to the measurement gap indicated (or configured) by the first information.

[0104] As another example: If the network device has not configured the NR MO and / or the second E-UTRA MO for the terminal device that requires a measurement gap to perform measurements, the network device can configure a new measurement gap for the terminal device and indicate (or configure) the measurement gap through the first information. After the terminal device receives the first information, it can measure the first E-UTRA MO according to the measurement gap indicated (or configured) by the first information.

[0105] In a possible implementation, when the MO that the terminal device needs to measure includes a first E-UTRA MO that has scheduling restrictions and does not require measurement gaps for measurement, the network device may also send first information to the terminal device that does not indicate (or configure) a measurement gap and does not indicate (or configure) a measurement window, indirectly / implicitly indicating that the first E-UTRA MO is not to be measured. After receiving the first information that does not indicate (or configure) a measurement gap and does not indicate (or configure) a measurement window, the terminal device does not measure the first E-UTRA MO.

[0106] As an example: when the channel occupancy between the network device and the terminal device is greater than a first threshold, or the amount of data to be transmitted (or scheduled) between the network device and the terminal device is greater than a second threshold, when the terminal device needs to measure the first E-UTRA MO, the network device may send the first information without indicating (or configuring) a measurement gap or without indicating (or configuring) a measurement window to the terminal device, so that the terminal device does not measure the first E-UTRA MO, thereby avoiding interruption of data transmission between the network device and improving data transmission efficiency.

[0107] In some implementations, before receiving the first information from the network device, the terminal device may further report to the network device that the terminal device does not need a measurement gap to perform the first E-UTRA MO measurement.

[0108] As an example: the terminal device may send second information to the network device, and the second information indicates that the terminal device supports performing E-UTRA measurements without measurement gaps when the E-UTRA CRS is completely included in the BWP activated by the terminal device. After the network device receives the second information, if it is determined that a certain E-UTRA CRS configured for the terminal device (such as the first E-UTRA MO) is completely included in the BWP activated by the terminal device, the network device may determine that the E-UTRA MO does not require measurement gaps to perform measurements. It can be understood that the E-UTRA MO being completely included in the BWP activated by the terminal device may mean that the frequency range corresponding to the E-UTRA MO is located in or belongs to the frequency range of the BWP activated by the terminal device, or the frequency range corresponding to the E-UTRA MO is part or all of the frequency range of the BWP activated by the terminal device.

[0109] Among them, the second information can be included in the R18 inter-system gapless measurement (interRAT-LTE-Meas-NoGapNoInterr-r18) message (also called capability message), which can be sent to the network device through one message or multiple messages. This application does not limit this.

[0110] As another example: the second information may also indicate one or more E-UTRA bands for which the terminal device does not need measurement gaps to perform E-UTRA measurements. For example: the terminal device may use the second information to indicate that the first E-UTRA band does not need measurement gaps to perform E-UTRA measurements, or indicates that the first E-UTRA band does not need measurement gaps and does not require NCSG to perform E-UTRA measurements, and the first E-UTRA MO configured by the network device for the terminal device corresponds to the first E-UTRA band, and the network device may determine that the first E-UTRA MO does not need measurement gaps to perform measurements. It can be understood that the first E-UTRA MO corresponds to the first E-UTRA band, which may mean that the frequency range corresponding to the first E-UTRA MO is located in or belongs to the first E-UTRA band, or the frequency range corresponding to the first E-UTRA MO is part or all of the first E-UTRA band.

[0111] Among them, the second information can be included in the EUTRA gap and NCSG requirement information (needForGapNCSG-InfoEUTRA) element in the RRC reconfiguration complete (RRCReconfigurationComplete) message or the RRC recovery complete (RRCResumeComplete) message, and can be sent to the network device through one message or multiple messages. This application does not limit this.

[0112] In a possible implementation, the second information may be reported in the measurement gap and NCSG requirement information field or indication field in an RRC reconfiguration complete (RRCReconfigurationComplete) message or an RRC recovery complete (RRCResumeComplete) message.

[0113] In one possible implementation, the band range reported by the terminal device (such as the first E-UTRA band mentioned above) can be requested by the network device, for example, it can be determined based on whether a measurement gap is required and the E-UTRA target band for NCSG to perform measurement in the RRC reconfiguration (RRCReconfiguration) message or RRC recovery (RRCResume) message sent by the network device.

[0114] Referring to the schematic table of the relationship between MO types, measurement gaps and measurement windows shown in Table 2, which is different from the two cases in Table 1 that the network device indicates (or configures) measurement gaps and measurement windows for the terminal device, or the network device only indicates (or configures) measurement windows for the terminal device, in an embodiment of the present application, the network device can also only indicate (or configure) the measurement window to the terminal device when the MO that the terminal device needs to measure includes an E-UTRA MO that has scheduling restrictions and does not require measurement gaps to perform measurements (corresponding to the fourth row of Table 2). Under this configuration or indication, for NR MO and E-UTRA MO that require measurement gaps to perform measurements, the terminal device performs measurements within the measurement gap; for NR MO that does not require measurement gaps to perform measurements, the terminal device can decide at what time domain position to measure based on the time domain position of the SMTC corresponding to the NR MO; for E-UTRA MO that has scheduling restrictions and does not require measurement gaps to perform measurements, the terminal device can perform measurements at the corresponding time domain position based on the measurement gap; for E-UTRA MO that does not have scheduling restrictions and does not require measurement gaps to perform measurements, the terminal device can perform measurements at any time domain position.

[0115] In addition, when the MO that the terminal device needs to measure includes an E-UTRA MO that has scheduling restrictions and does not require measurement gaps to perform measurements, the network device may not indicate (or configure) the measurement gap and measurement window to the terminal device (corresponding to the 5th row of Table 2). Under this configuration or indication, the terminal device does not perform measurements on the E-UTRA MO that has scheduling restrictions and does not require measurement gaps to perform measurements; for the E-UTRA MO that does not have scheduling restrictions and does not require measurement gaps to perform measurements, the terminal device can perform measurements at any time domain location.

[0116] Table 2

[0117] In some implementations, for scenarios where the network device indicates (or configures) a measurement gap and a measurement window, a conflict may occur between the first measurement opportunity corresponding to the measurement gap and the second measurement opportunity corresponding to the measurement window. In an embodiment of the present application, the conflict between the measurement gap and the measurement window can be avoided, or the behavior of the terminal device in the conflict scenario can be defined to solve the problem of how to measure MO in scenarios where the network device indicates (or configures) a measurement gap and a measurement window.

[0118] FIG5 is a schematic diagram of another measurement method provided in an embodiment of the present application, the method comprising:

[0119] S501: A network device sends third information to a terminal device, and the terminal device receives the third information accordingly. The third information indicates (or configures) a measurement gap and a measurement window, where the measurement gap corresponds to at least one first measurement opportunity and the measurement window corresponds to at least one second measurement opportunity.

[0120] In the embodiment of the present application, at least one measurement opportunity corresponding to the measurement gap may be determined according to the configuration of the measurement gap, such as one or more of a measurement gap repetition period (MGRP), a measurement gap length (MGL), a measurement gap offset (gapOffset) used to configure a starting position of the measurement gap, etc. At least one second measurement opportunity corresponding to the measurement window may be determined according to the configuration of the measurement window, such as one or more of a measurement window period, a measurement window offset, and a window duration of the measurement window.

[0121] S502: When at least one first measurement opportunity and at least one second measurement opportunity do not conflict, the terminal device performs measurement according to the at least one first measurement opportunity and the at least one second measurement opportunity.

[0122] In an embodiment of the present application, the network device can avoid conflicts between measurement opportunities corresponding to the measurement gap and the measurement window by controlling the time domain positions of at least one first measurement opportunity corresponding to the measurement gap and at least one second measurement opportunity corresponding to the measurement window.

[0123] For example: the network device configures at least one first measurement opportunity corresponding to the measurement time slot for the terminal device, which usually includes the duration of the SMTC corresponding to the NR MO to be measured, so that the terminal device can measure the NR MO within at least one first measurement opportunity corresponding to the measurement time slot. Therefore, in some implementations, the measurement window offset can be set according to the configuration of the SMTC to avoid conflicts between the measurement gap and the measurement opportunity corresponding to the measurement window.

[0124] Taking the measurement window period as an integral multiple of the SMTC period as an example, the measurement window offset of the measurement window may satisfy Formula 1: (n-1)*smtc_periodicity+smtc_offset+smtc_duration≤window_offset≤n*smtc_periodicity+smtc_offset-window_duration.

[0125] Taking the SMTC period as an integral multiple of the measurement window period as an example, the measurement window offset of the measurement window may satisfy Formula 2: (n-1)*window_periodicity+window_offset+window_duration≤smtc_offset≤n*window_periodicity+window_offset-smtc_duration.

[0126] Among them, window_offset represents the measurement window offset, smtc_offset represents the SMTC offset, window_duration represents the window duration of the measurement window, smtc_periodicity represents the SMTC period, smtc_duration represents the SMTC duration, window_periodicity represents the measurement window period, n=0,1,2..., the measurement gap is determined according to smtc_offset, smtc_periodicity, and smtc_duration.

[0127] It should be understood that the measurement window offset can be greater than or equal to 0 and less than or equal to the difference between the measurement window period and the window duration of the measurement window. Similarly, the SMTC offset can be greater than or equal to 0 and less than or equal to the difference between the SMTC period and the SMTC duration.

[0128] In some implementations, when the measurement window period is an integer multiple of the SMTC period, the value of n can be a natural number not greater than the ratio of the measurement window period to the SMTC period; when the SMTC period is an integer multiple of the measurement window period, the value of n can be a natural number not greater than the ratio of the SMTC period to the measurement window.

[0129] Optionally, in order to avoid the measurement window offset being outside the measurement window period range, the measurement window offset of the measurement window can simultaneously satisfy the above formula 1 or formula 2, as well as the condition that the measurement window offset is greater than or equal to 0 and less than or equal to the difference between the measurement window period and the window duration of the measurement window.

[0130] The above formula can be used to limit the measurement window to end before the start of SMTC, and the measurement window can be started only after the end of SMTC. Therefore, when the SMTC configuration is fixed, the time domain position of the measurement window (that is, the measurement opportunity corresponding to the measurement window) is placed in the middle gap of SMTC (that is, the middle time domain position). This configuration method is suitable for the case where the period of SMTC and the measurement window is a multiple relationship (such as the SMTC period is a multiple of the measurement window period, or the measurement window period is a multiple of the SMTC). In addition, for staggering, in some implementations, it can also be required that the distance between any SMTC and the measurement window (that is, the measurement opportunity corresponding to the measurement window) be greater than 4ms to ensure that the terminal device has sufficient switching time when there is a need to switch SCS, working frequency band (or frequency point), etc.

[0131] 6, taking the SMTC period as 20ms, the SMTC offset as 9ms, the SMTC duration as 2ms, the measurement window period as 40ms, and the measurement window duration as 2ms as an example, the value of n can be 0, 1, or 2. When n is 0, according to (n-1)*smtc_periodicity+smtc_offset+smtc_duration≤window_offset≤n*smtc_periodicity+smtc_offset-window_duration, it can be seen that window_offset can be a value greater than or equal to -9 and less than or equal to 7; when n is 1, according to (n-1)*smtc_periodicity+smtc _offset+smtc_duration≤window_offset≤n*smtc_periodicity+smtc_offset-window_duration, it can be seen that window_offset can be a value greater than or equal to 11 and less than or equal to 27; when n is 2, according to (n-1)*smtc_periodicity+smtc_offset+smtc_duration≤window_offset≤n*smtc_periodicity+smtc_offset-window_duration, it can be seen that window_offset can be a value greater than or equal to 31 and less than or equal to 47. In summary, when n is 0, 1, or 2, window_offset can be a value greater than or equal to -9 and less than or equal to 7, or a value greater than or equal to 11 and less than or equal to 27, or a value greater than or equal to 31 and less than or equal to 47.

[0132] Optionally, to prevent the measurement window offset from being outside the measurement window period, window_offset (i.e., the measurement window offset) is greater than or equal to 0 and less than or equal to 40 (the measurement window period) - 2 (the window duration of the measurement window). For example, in conjunction with this condition, when n is 0, 1, or 2, window_offset can be a value greater than or equal to 0 and less than or equal to 7, or a value greater than or equal to 11 and less than or equal to 27, or a value greater than or equal to 31 and less than or equal to 38. In Figure 6, a window_offset of 19 is used as an example. In Figure 6, EMTC represents the measurement window (or the measurement opportunity corresponding to the measurement window).

[0133] It should be understood that in some implementations, the above-mentioned SMTC may also refer to the measurement gap, that is, the above-mentioned SMTC offset (smtc_offset), SMTC period (smtc_periodicity), and SMTC duration (smtc_duration), and may also refer to the measurement gap offset, measurement gap period (or measurement gap repetition period), and measurement gap duration.

[0134] S503: When the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device measures the MO according to one or more of the priorities of the measurement gap and the measurement window, the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window, the measurement gap ratio of each type of MO, etc.

[0135] The first target measurement opportunity belongs to the at least one first measurement opportunity, and the second target measurement opportunity belongs to the at least one second measurement opportunity.

[0136] It can be understood that the conflict between the first target measurement opportunity and the second target measurement opportunity may mean that the time domain positions of the first target measurement opportunity and the second target measurement opportunity partially or completely overlap, or the interval between the time domain positions of the first target measurement opportunity and the second target measurement opportunity is less than the interval threshold.

[0137] Implementation 1: When the first target measurement opportunity conflicts with the second target measurement opportunity, if the MO that the terminal device needs to measure includes an NR MO with scheduling restrictions (such as an NR MO that requires measurement gaps to perform measurements), the terminal device can abandon the second target measurement opportunity, or measure the MO according to the first target measurement opportunity. For example, according to the first target measurement opportunity, the NR MO with scheduling restrictions is measured, and so on. It can be understood that in the embodiment of the present application, abandonment can also be understood as discarding, giving up, etc., and no additional explanation will be given.

[0138] Alternatively, in the case where the first target measurement timing conflicts with the second target measurement timing, if the MO that the terminal device needs to measure includes an NR MO with scheduling restrictions, the terminal device may also abandon the inter-system E-UTRA measurement. For example: in the case where the first target measurement timing conflicts with the second target measurement timing, if the MO that the terminal device needs to measure includes an NR MO with scheduling restrictions, the terminal device may abandon the second target measurement timing for E-UTRA measurement, or measure the MO according to the first target measurement timing. For example, according to the first target measurement timing, the NR MO with scheduling restrictions is measured, and so on.

[0139] That is, when EMW is configured overlapped with SMTC / SSB / CSI-RS measurement and when NR measurement causes scheduling restriction, inter-RAT LTE measurement will be dropped.

[0140] As an example: referring to Figure 7, taking the measurement gap corresponding to 4 first measurement opportunities (first measurement opportunities 1-4) and the measurement window corresponding to 2 second measurement opportunities (second measurement opportunities 1 and 2) as an example, where the second measurement opportunity 1 conflicts with the first measurement opportunity 1. If the terminal device needs to measure the MO that contains a scheduling-restricted NR MO, the terminal device can measure the NR MO with scheduling restrictions according to the first measurement opportunity 1; similarly, the second measurement opportunity 2 conflicts with the first measurement opportunity 3. If the terminal device needs to measure the MO that contains a scheduling-restricted NR MO, the terminal device can also measure the NR MO with scheduling restrictions according to the first measurement opportunity 3.

[0141] Implementation 2: When the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device can abandon the second target measurement opportunity or measure the MO according to the first target measurement opportunity. For example, the terminal device can measure the NR MO with scheduling restrictions according to the first target measurement opportunity.

[0142] Alternatively, if the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device may abandon the inter-system E-UTRA measurement. For example, if the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device may abandon the second target measurement opportunity used for E-UTRA measurement, or measure the MO based on the first target measurement opportunity. For example, based on the first target measurement opportunity, the terminal device may measure the NR MO with scheduling restrictions.

[0143] Implementation 3: If a measurement gap is indicated (or configured) but a measurement window is not configured; or if a measurement gap and a measurement window are indicated (or configured), but there is a conflict between the first target measurement opportunity and the second target measurement opportunity in the first measurement opportunity corresponding to the measurement gap and the second measurement opportunity corresponding to the measurement window, the terminal device can measure the heterogeneous E-UTRA MO with scheduling restrictions. It can be understood that if the measurement gap and the measurement window are indicated (or configured), the terminal device can measure the heterogeneous E-UTRA MO with scheduling restrictions when there is a conflict between the first target measurement opportunity and the second target measurement opportunity, thereby solving the problem of how the terminal device performs measurement when there is a conflict between the first target measurement opportunity and the second target measurement opportunity.

[0144] For example: the network device indicates (or configures) a measurement gap but does not configure a measurement window. The terminal device can measure the heterogeneous system E-UTRA MO with scheduling restrictions according to the first measurement opportunity corresponding to the measurement gap.

[0145] The network device indicates (or configures) a measurement gap and a measurement window, but there is a conflict between the first target measurement opportunity and the second target measurement opportunity in the first measurement opportunity corresponding to the measurement gap and the second measurement opportunity corresponding to the measurement window. The terminal device can measure the heterogeneous system E-UTRA MO with scheduling restrictions according to the first target measurement opportunity (or the second target measurement opportunity). In the case of a conflict between the first target measurement opportunity and the second target measurement opportunity, whether the terminal device measures the heterogeneous system E-UTRA MO with scheduling restrictions according to the first target measurement opportunity or the second target measurement opportunity can be defined by a protocol, configured by a network device, or determined independently by the terminal device, and this application does not limit this.

[0146] Implementation 4: Take the case where the first target measurement opportunity conflicts with the second target measurement opportunity, and the terminal device measures the MO according to the priority of the measurement gap and the measurement window as an example. In a possible implementation, when the priority of the measurement gap is greater than or equal to the priority of the measurement window, the terminal device can measure the MO according to the first target measurement opportunity. For example, the NR MO that requires measurement gaps to perform measurements is measured within the first target measurement opportunity. When the priority of the measurement gap is less than the priority of the measurement window, the terminal device can measure the MO according to the second target measurement opportunity. For example: the terminal device can measure the E-UTRA MO that has scheduling restrictions and does not require measurement gaps to perform measurements within the second measurement opportunity.

[0147] It can also be understood that when the priority of the measurement gap is equal to the priority of the measurement window, the terminal device can also measure the MO according to the second target measurement opportunity. The present application does not limit the target measurement opportunity selected by the terminal device for MO measurement when the priority of the measurement gap is equal to the priority of the measurement window.

[0148] The priority of the measurement gap and the priority of the measurement window can be defined by a protocol, etc., or can be indicated (or configured) to the terminal device by the network device. This application does not limit the way in which the terminal device obtains the priority of the measurement gap and the priority of the measurement window.

[0149] As an example: the network device may send fourth information indicating the priority of the measurement gap and / or the priority of the measurement window to the terminal device, and indicate (or configure) the priority of the measurement gap and / or the priority of the measurement window to the terminal device.

[0150] Implementation 5: Taking the case where the first target measurement opportunity conflicts with the second target measurement opportunity, the terminal device measures the MO according to the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window as an example. In one possible implementation, when the number of first measurement opportunities corresponding to the measurement gap is greater than or equal to the number of second measurement opportunities corresponding to the measurement window, the terminal device measures the MO according to the second target measurement opportunity; when the number of first measurement opportunities corresponding to the measurement gap is less than the number of second measurement opportunities corresponding to the measurement window, the terminal device measures the MO according to the first target measurement opportunity.

[0151] 7 , taking the case where the measurement gap corresponds to four first measurement opportunities (first measurement opportunities 1-4) and the measurement window corresponds to two second measurement opportunities (second measurement opportunities 1 and 2) as an example, where the second measurement opportunity 1 conflicts with the first measurement opportunity 1 and the second measurement opportunity 2 conflicts with the first measurement opportunity 3, the terminal device can measure the NR MO and the like that require measurement gaps for measurement at the first measurement opportunities 2 and 4, and can measure the E-UTRA MO and the like that have scheduling restrictions and do not require measurement gaps for measurement at the second measurement opportunities 1 and 2. According to the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window, measuring the MO can take into account the measurement requirements of the terminal device for measuring the MO in the measurement gap and the measurement window.

[0152] It can be understood that when the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window are equal, the terminal device can also measure the MO according to the first target measurement opportunity. This application does not limit the target measurement opportunity selected by the terminal device for MO measurement when the priority of the measurement gap is equal to the priority of the measurement window.

[0153] Implementation 6: Taking the case where the first target measurement opportunity conflicts with the second target measurement opportunity, and the terminal device measures the MO according to the measurement gap ratio of each type of MO as an example, in one possible implementation, the terminal device may determine the target type of the MO corresponding to the first target measurement opportunity based on the first measurement gap ratio of the same-frequency MO, the second measurement gap ratio of the different-frequency MO or the different-system MO other than the E-UTRA MO with scheduling restrictions, and the third measurement gap ratio of the E-UTRA MO with scheduling restrictions, and measure the MO of the target type at the first target measurement opportunity.

[0154] The current measurement gap sharing mechanism (MeasGapSharingScheme) defines the proportion of measurement gaps used for four types of intra-frequency measurements to the entire measurement gap. As shown in Table 3, parameter X represents the measurement gap ratio used for intra-frequency measurements when the measurement gap sharing mechanism is used. Depending on the value of MeasGapSharingScheme, parameter X has four values. When MeasGapSharingScheme is '00', the measurement gaps are evenly distributed (equal splitting) and parameter X is not used. When MeasGapSharingScheme is '01', '10' and '11', parameter X is 25, 50 and 75 respectively. The X% part represents the proportion of the measurement gap used for intra-frequency measurements, and the remaining (100-X)% part of the measurement gap is used for inter-frequency and inter-system (i.e., inter-RAT) measurements.

[0155] Table 3

[0156] In an embodiment of the present application, considering that when the measurement timing of the measurement gap and the measurement window conflicts, the current ratio of inter-frequency and inter-system (i.e., inter-RAT) measurements can be divided again into a part for inter-frequency MO or inter-system MO measurements other than E-UTRA MO with scheduling restrictions, and a part for E-UTRA MO measurements with scheduling restrictions.

[0157] In one possible implementation, the first measurement gap ratio is X, the second measurement gap ratio is 100-XY, and the third measurement gap ratio is Y. That is, for the first target measurement opportunity where the measurement gap conflicts with the measurement window, X% of the first target measurement opportunities are used for intra-frequency MO measurement, (100-XY)% of the first target measurement opportunities are used for inter-frequency MO or inter-system MO measurement other than E-UTRA MO with scheduling restrictions, and Y% of the first target measurement opportunities are used for E-UTRA MO measurement with scheduling restrictions. Wherein X and Y are natural numbers, X+Y is less than or equal to 100. X and Y can be defined by a protocol, etc., or can be indicated (or configured) to the terminal device by a network device, and this application does not limit this.

[0158] Taking X as 25, Y as 25, and 100-XY equals 50 as an example, the terminal device can determine that the first first target measurement opportunity is used for intra-frequency MO measurement, the second and third first target measurement opportunities are used for inter-frequency MO or inter-system MO measurement other than E-UTRA MO with scheduling restrictions, the fourth first target measurement opportunity is used for E-UTRA MO measurement with scheduling restrictions, and so on. The fifth first target measurement opportunity is used for intra-frequency MO measurement, and so on.

[0159] In addition, it can be understood that the above-mentioned X and Y can also be values ​​between 0 and 1, that is, they can be specific proportion values, for example, the first measurement gap proportion coefficient X is 0.25 (or 25%), the third measurement gap proportion coefficient Y is 0.10 (or 10%), and the second measurement gap proportion coefficient 1-XY is 0.65 (or 65%).

[0160] In another possible implementation, the first measurement gap proportion coefficient is X, the second measurement gap proportion coefficient is (100-X)*Q%, and the third measurement gap proportion coefficient is (100-X)*(100-Q)%. That is, for the first target measurement opportunity where the measurement gap conflicts with the measurement window, X% of the first target measurement opportunities are used for intra-frequency MO measurement, (100-X)%*Q% of the first target measurement opportunities are used for inter-frequency MO or inter-system MO measurement other than E-UTRA MO with scheduling restrictions, and (100-X)%*(100-Q)% of the first target measurement opportunities are used for E-UTRA MO measurement with scheduling restrictions. Wherein, X and Q are natural numbers less than or equal to 100. X and Q can be defined by a protocol, etc., or can be indicated (or configured) to the terminal device by a network device, and this application does not limit this.

[0161] In addition, it is understandable that the above X and Q can also be values ​​between 0 and 1, that is, they can be specific ratios. For example, if the first measurement gap ratio X is 0.25, the second measurement gap ratio (1-X)*Q is (1-0.25)*0.90, and the second measurement gap ratio (1-X)*(1-Q) is (1-0.25)*(1-0.90), and so on.

For details, please refer to the relevant description of the above-mentioned method embodiment.

[0163] As shown in Figure 8, a communication device 800 includes a processing unit 810 and an interface unit 820.

[0166] In one possible design, before receiving the first information from the network device, the interface unit 820 is further configured to send second information to the network device, where the second information indicates that the communication device supports performing E-UTRA measurements without requiring measurement gaps when the E-UTRA CRS is completely contained by a BWP activated by the communication device, wherein the first E-UTRA MO is completely contained by the BWP; or, the second information indicates that the first E-UTRA band does not require measurement gaps to perform E-UTRA measurements, and the first E-UTRA MO corresponds to the first E-UTRA band.

[0169] In one possible design, when the first target measurement opportunity conflicts with the second target measurement opportunity, the processing unit 810 measures the MO according to the priorities of the measurement gap and the measurement window. Specifically, when the priority of the measurement gap is greater than or equal to the priority of the measurement window, the MO is measured according to the first target measurement opportunity; when the priority of the measurement gap is less than the priority of the measurement window, the MO is measured according to the second target measurement opportunity.

[0170] In one possible design, the interface unit 820 is further used to receive fourth information from the network device, where the fourth information is used to indicate the priority of the measurement gap and / or the priority of the measurement window.

[0171] In one possible design, when the first target measurement opportunity conflicts with the second target measurement opportunity, the processing unit 810 measures the MO according to the number of first measurement opportunities corresponding to the measurement gap and the number of second measurement opportunities corresponding to the measurement window.

[0173] Exemplarily, the first measurement gap proportion coefficient is X, the second measurement gap proportion coefficient is 100-XY, and the third measurement gap proportion coefficient is Y, where X and Y are natural numbers, and X+Y is less than or equal to 100.

[0176] In one possible design, the interface unit 820 is further used to receive second information from the terminal device before the processing unit 810 configures the first E-UTRA MO for the terminal device, where the second information indicates that the terminal device supports performing E-UTRA measurements without measurement gaps when the E-UTRA CRS is completely contained by the BWP activated by the terminal device, wherein the first E-UTRA MO is completely contained by the BWP; or, the second information indicates that the first E-UTRA band does not require measurement gaps to perform E-UTRA measurements, and the first E-UTRA MO corresponds to the first E-UTRA band.

[0177] In one possible design, the measurement gap indicated by the first information is determined based on a new radio NR MO or a second E-UTRA MO configured for the terminal device that requires a measurement gap to perform measurements.
