[0021] An introduction to NTN technology: Currently, relevant standards organizations are researching NTN technology, which provides communication services to ground users via satellite (or drones) instead of ground base stations. Compared to terrestrial cellular communication networks, satellite communication has many unique advantages. First, satellite communication is not limited by the user's geographical location. For example, conventional terrestrial communication cannot cover areas such as oceans, mountains, and deserts where communication equipment cannot be installed or where there is no communication coverage due to sparse population. However, for satellite communication, a single satellite can cover a large area, and since satellites orbit the Earth, theoretically every corner of the Earth can be covered by satellite communication. Second, satellite communication has significant social value. Satellite communication can provide coverage in remote mountainous areas and impoverished countries or regions at a relatively low cost, enabling people in these areas to enjoy advanced voice communication and mobile internet technologies, helping to narrow the digital divide with developed regions and promoting development in these areas. Third, satellite communication has a long range, and the cost of communication does not increase significantly with increasing distance. Finally, satellite communication is highly stable and is not affected by natural disasters.

[0022] In some embodiments, communication satellites are classified according to their orbital altitude as Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, and so on.

[0023] 1. LEO In some embodiments, the low-Earth orbit satellites have an altitude range of 300km-1500km, with corresponding orbital periods of approximately 1.5 hours to 2 hours. The signal propagation delay for single-hop communication between users is generally less than 20ms. The maximum satellite visibility time is 20 minutes. The short signal propagation distance and low link loss mean that the requirements for the transmit power of user terminals are not high.

[0024] 2. GEO In some embodiments, the geostationary orbit satellite has an orbital altitude of 35,786 km and an orbital period of 24 hours around the Earth. The signal propagation delay for single-hop communication between users is typically 250 ms.

[0025] Table 1 shows the satellite altitude, orbit, and coverage area of ​​a typical NTN network:

[0026] Figure 1A schematic diagram of a communication system 10 provided in an exemplary embodiment of this application is shown. The communication system 10 includes: a terminal 110, a satellite 120, and an NTN gateway 130. The terminal 110 communicates with the satellite 120 via a service link, the satellite 120 communicates with the NTN gateway 130 via a feeder link, and the NTN gateway 130 communicates with a data network.

[0027] It should be noted that, Figure 1 The number of communication devices in the illustrated communication system is for illustrative purposes only. There can be multiple communication devices, and the connection relationships can be changed according to actual circumstances. Figure 1 The examples provided are not intended to limit the communication system provided in the embodiments of this application. For example, Figure 1 Only one terminal is shown in the image; in some embodiments, Figure 1 The communication system shown can accommodate more terminals and communicate with satellite 120.

[0028] In some embodiments, the Internet of Things (IoT) terminal includes at least one of the following: a Bandwidth reduction and Low complexity UE (BL UE), a UE in Coverage Enhancement mode (UE in CE mode), and a Narrow Band Internet of Things UE (NB-IoT UE).

[0029] To ensure satellite coverage and improve the overall capacity of the satellite communication system, satellites use multi-beam coverage to cover the ground. A single satellite can generate dozens or even hundreds of beams to cover the ground, and a single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers, forming a beam coverage area.

[0030] The method provided in this application embodiment can be applied to NTN systems, such as... Figure 2 and Figure 3 As shown, an example of the NTN system is provided.

[0031] Figure 2This illustration shows a schematic diagram of an NTN system provided in an exemplary embodiment of this application. The communication satellite in this NTN system is a transparent transmission mode satellite. The NTN system includes: a terminal 110, a satellite (or UAV system platform) 120, an NTN gateway 130, an access network device 210, and a core network device 220. In some embodiments, the satellite 120 and the NTN gateway 130 can form a unit in the NTN system. For example, this unit can be called a remote radio unit; in some embodiments, this unit may also have other names, which are not limited in this embodiment. The remote radio unit and the access network device 210 can form an access network, which can be called a Next Generation Radio Access Network (NG-RAN); in some embodiments, this access network may also have other names, which are not limited in this embodiment.

[0032] It should be noted that, Figure 2 The number of communication devices shown in the NTN system is for illustrative purposes only. There can be multiple communication devices, and the connection relationships can be changed according to actual circumstances. Figure 2 The examples provided are not intended to limit the NTN system provided in the embodiments of this application. For example, Figure 2 Only one terminal is shown in the image; in some embodiments, Figure 2 The communication system shown can accommodate more terminals and communicate with the core network equipment 220 through the access network.

[0033] In some embodiments, terminal 110 and access network device 210 communicate via the NR Uu interface. Figure 2 In the architecture shown, the access network device 210 can be deployed on the ground. Uplink and downlink communication between the terminal 110 and the access network device 210 can be relayed through satellite 120 and NTN gateway 130 (usually located on the ground). The terminal 110 communicates with satellite 120, satellite 120 communicates with NTN gateway 130, NTN gateway 130 communicates with access network device 210, access network device 210 communicates with core network device 220 through NG interface, and core network device 220 communicates with data network through N6 interface.

[0034] In this NTN system, satellite 120 has the function of frequency conversion and signal amplification. Satellite 120 does not demodulate the signal of access network equipment 210, but only converts the signal to the satellite frequency band for transmission. Satellite 120 is similar to a repeater.

[0035] Figure 3This illustration shows a schematic diagram of an NTN system provided in an exemplary embodiment of this application. The communication satellite in this NTN system is a regenerative mode satellite. The NTN system includes: a terminal 110, a satellite 120, an NTN gateway 130, and a core network device 220. The satellite 120 and the NTN gateway 130 can form an access network, which may be called NG-RAN. In some embodiments, the access network may also have other names, which are not limited in this embodiment.

[0036] It should be noted that, Figure 3 The number of communication devices shown in the NTN system is for illustrative purposes only. There can be multiple communication devices, and the connection relationships can be changed according to actual circumstances. Figure 3 The examples provided are not intended to limit the NTN system provided in the embodiments of this application. For example, Figure 3 Only one terminal is shown in the image; in some embodiments, Figure 3 The communication system shown can accommodate more terminals and communicate with the core network equipment 220 through the access network.

[0037] In some embodiments, the functions of access network device 210 are integrated on satellite 120, meaning satellite 120 possesses the functions of access network device 210. Terminal 110 and satellite 120 communicate via the NR Uu interface, satellite 120 and NTN gateway 130 communicate via Satellite Radio Interface (SRI), NTN gateway 130 communicates with core network device 220 via the NG interface, and core network device 220 communicates with the data network via the N6 interface. In this NTN system, satellite 120 receives signals, demodulates and decodes them, then re-encodes and modulates them (i.e., the regeneration process), and transmits the regenerated signals via the satellite frequency band.

[0038] exist Figure 2 and Figure 3 In the illustrated architecture, access network device 210 is a device used to provide wireless communication services to terminal 110. Access network device 210 and terminal 110 can establish a connection to communicate, including signaling and data exchange. There can be multiple access network devices 210, and two adjacent access network devices 210 can communicate via wired or wireless means. Terminal 110 can switch between different access network devices 210, that is, establish connections with different access network devices 210.

[0039] Taking a cellular communication network as an example, the access network device 210 in the cellular communication network can be a base station. A base station is a device deployed in the access network to provide wireless communication functions for the terminal 110. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functions may differ. For example, in a 5th Generation New Radio (5G NR) communication system, it is called a Next Generation Node B (gNB). As communication technologies evolve, the name "base station" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functions for the terminal 110 are collectively referred to as base stations or access network devices.

[0040] Furthermore, the terminal 110 involved in this application embodiment may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of UEs, mobile stations (MS), terminals, etc. For ease of description, the devices mentioned above are collectively referred to as terminals in this application embodiment. In this application, "UE" is used in some places to represent "terminal". In this application embodiment, "network device" may be an access network device (such as a base station) or a satellite.

[0041] Furthermore, taking a 5G NTN system as an example, an NTN system can include multiple satellites 120. One satellite 120 can cover a certain area of ​​the ground, providing wireless communication services to terminals 110 in that area. In addition, satellites 120 can orbit the Earth, and by deploying multiple satellites 120, communication coverage of different areas on the Earth's surface can be achieved.

[0042] In the embodiments of this application, the terms "network" and "system" are often used interchangeably, but those skilled in the art will understand their meanings. The technical solutions described in the embodiments of this application can be applied to Long Term Evolution (LTE) systems, 5G systems, subsequent evolution systems of 5G NR systems, or other communication systems, and this application does not limit them in this regard.

[0043] It should be noted that the above schematic diagrams and descriptions of the communication system and NTN system are for illustrative purposes only. Furthermore, the methods provided in this application embodiment can be applied not only to the above-mentioned NTN system, but also to other communication systems, such as subsequent evolution systems of the above-mentioned NTN system. This application embodiment does not limit this application.

[0044] An introduction to GNSS measurements: The principle of GNSS measurement is that the terminal measures the distance between itself and satellites at known locations, and then combines data from multiple satellites to determine the terminal's exact location. To achieve this, the satellite's position can be found in the satellite's ephemeris based on the time recorded by its onboard clock. The distance from the terminal to the satellite is approximated by recording the time it takes for the satellite signal to travel to the terminal and then multiplying that time by the speed of light.

[0045] The terminal's location can be determined by the GNSS measurement results (GNSS position fix) obtained through GNSS measurements. Some terminals communicating via NTN cannot simultaneously perform GNSS measurements (reception) and Long Term Evolution (LTE) message transmission and reception; these include some Internet of Things (IoT) terminals. Furthermore, the validity of the GNSS measurement results acquired by the terminal is only maintained for a limited time; after this period, the GNSS measurement results become outdated. At this time, the terminal needs to perform GNSS measurements again to obtain new GNSS measurement results, thereby accurately determining its location (the terminal may have moved, causing previous measurement results to be inaccurate). Because the terminal cannot simultaneously perform GNSS measurements and LTE message transmission and reception, it can only perform one of them, which may lead to the inability to perform GNSS measurements during message transmission and reception.

[0046] The method provided in this application configures a first measurement gap for GNSS measurements on the terminal, enabling the terminal to perform GNSS measurements within that first measurement gap. This first measurement gap can be set according to actual conditions, for example, it can be set during the terminal's LTE message transmission and reception process, thus avoiding the problem of the terminal being unable to perform GNSS measurements if the terminal's GNSS measurement results are invalid.

[0047] Figure 4 A flowchart of a communication method provided in one embodiment of this application is shown. This method can be applied to a terminal. The method includes: Step 402: Obtain configuration information, which is used to configure the first measurement gap.

[0048] The first measurement gap is used for GNSS measurement. After the terminal acquires the first measurement gap, it can perform GNSS measurement within the first measurement gap to obtain the GNSS measurement result.

[0049] In some embodiments, the first measurement gap may be referred to as a GNSS measurement gap. In some embodiments, the first measurement gap may have other names, such as a measurement gap for GNSS measurement, a measurement gap dedicated to GNSS measurement, and a gap for performing GNSS measurement, etc. The specific name of the first measurement gap is not limited in the embodiments of this application.

[0050] GNSS measurement results are information obtained by a terminal through GNSS measurements to determine its location. In some embodiments, GNSS measurement results have other names, such as GNSS positioning. This application does not limit the specific name of the GNSS measurement results.

[0051] In some embodiments, the terminal obtains the first measurement gap for GNSS measurements by receiving the aforementioned configuration information. For example, the terminal obtains the first measurement gap for GNSS measurements by receiving the aforementioned configuration information sent by a network device. The terminal can also receive the aforementioned configuration information sent by other communication devices to obtain the first measurement gap, but this application embodiment does not limit this.

[0052] In some embodiments, the above configuration information can also be pre-configured in the terminal, and the terminal obtains the first measurement gap of GNSS measurement based on the configuration information pre-configured in the terminal.

[0053] Optionally, the terminal acquiring the first measurement gap may not support simultaneous GNSS measurement and LTE message transmission / reception. For example, the terminal may be an IoT terminal. If the IoT terminal does not support simultaneous GNSS measurement and LTE message transmission / reception, the first measurement gap can be set during the terminal's LTE message transmission / reception process. The first measurement gap can also be set at other time periods, such as during the terminal's execution of other processes, as described in this embodiment.

[0054] Configuration for the first measuring gap: In some embodiments, the terminal obtains the first measurement gap by receiving configuration information sent by a network device, which is used to indicate the first measurement gap.

[0055] Optionally, the above configuration information includes at least one of the following: • Starting System Frame Number (SFN) and subframes; • Repeating cycle; • Offset; • Gap length; • Timing Advance (TA) of the gap; • Gap type; • Gap markings; • Gap priority; • Information indicating whether the gap is used for GNSS measurements; • Gap sharing strategy.

[0056] Optionally, the starting SFN of the measurement gap and the subframe are used to indicate the starting position of the measurement gap in the time domain as indicated by the configuration information.

[0057] Optionally, the repetition period of the measurement gap is used to indicate the periodic repetition of the measurement gap indicated by the configuration information in the time domain.

[0058] Optionally, the offset of the measurement gap is used to indicate the offset of the starting position of the measurement gap in the time domain, as indicated by the configuration information, relative to the reference position.

[0059] Optionally, the gap length of the measurement gap is used to indicate the duration of the measurement gap, as indicated by the configuration information, in the time domain.

[0060] Optionally, the timing interval (TA) during the measurement gap is used to ensure time alignment. In the event of a delay during information transmission, to ensure time alignment between the terminal and network equipment, the terminal needs to perform a timing advance for GNSS measurements during the first measurement gap, thereby achieving time alignment with the network equipment.

[0061] Optionally, the type of measurement gap is used to reflect the configuration mode of the measurement gap indicated by the configuration information, such as configuring a measurement gap per UE, or configuring a measurement gap per FR1 gap for each frequency range 1 (FR1), or configuring a measurement gap per FR2 gap for each frequency range 2 (FR2), where FR1 and FR2 are two frequency ranges specified by 5G NR.

[0062] Optionally, the gap identifier is used to identify the measurement gap indicated by the configuration information, such as the identity document (ID) of the measurement gap.

[0063] Optionally, the measurement gap priority is used to indicate the priority of GNSS measurements when the terminal performs measurements other than GNSS measurements within the measurement gap indicated by the configuration information. For example, measurements other than GNSS measurements include co-channel cell measurements, adjacent channel cell measurements, and serving cell measurements.

[0064] Optionally, the information indicating whether the gap is used for GNSS measurement is used to indicate whether the measurement gap indicated by the configuration information is used for GNSS measurement, that is, whether the measurement gap indicated by the configuration information is the first measurement gap used for GNSS measurement. In some embodiments, the information indicating whether the gap is used for GNSS measurement is information indicating that the gap is used for GNSS measurement. In some embodiments, the information indicating whether the gap is used for GNSS measurement is information indicating that the gap is not used for GNSS measurement.

[0065] In addition to including information indicating whether the measurement gap is used for GNSS measurement in the configuration information of the configuration information, thereby directly indicating to the terminal whether the measurement gap configured in the configuration information is used for GNSS measurement, other methods can also be used to indicate to the terminal whether the measurement gap configured in the configuration information is used for GNSS measurement.

[0066] In some embodiments, the configuration information described above does not carry information indicating whether the gap is used for GNSS measurement. If the configuration information obtained by the terminal includes one or more target information from the configuration information, the terminal will determine that the measurement gap configured in the configuration information is used for GNSS measurement. This target information is predefined. For example, if the target information is the gap sharing strategy described above, then if the configuration information includes the gap sharing strategy, the terminal will determine that the measurement gap configured in the configuration information is used for GNSS measurement.

[0067] In some embodiments, the configuration information is sent from the network device to the terminal. The network device can send configuration information to the terminal multiple times to indicate whether the measurement gaps configured in the configuration information are used for GNSS measurements. In some embodiments, the network device first sends configuration information to the terminal without indicating whether the gaps are used for GNSS measurements, so that the terminal obtains the measurement gaps configured in the configuration information, but at this time the terminal does not know the purpose of the measurement gaps configured in the configuration information. Subsequently, the network device sends configuration information to the terminal carrying information indicating whether the gaps are used for GNSS measurements, so that the terminal knows whether the previously configured measurement gaps are used for GNSS measurements. For example, when the terminal needs to perform GNSS measurements, the network device sends configuration information carrying information indicating that the gaps are used for GNSS measurements, so that the terminal knows that the previously configured measurement gaps are used for GNSS measurements.

[0068] In some embodiments, the configuration information pre-configured in the terminal does not include information indicating whether the gap is used for GNSS measurement. The network device will send configuration information carrying information indicating whether the gap is used for GNSS measurement to the terminal, so as to indicate whether the measurement gap indicated by the configuration information pre-configured in the terminal is used for GNSS measurement.

[0069] It should be noted that the above configuration information may also include other information different from the information indicating whether the gap is used for GNSS measurement. This other information can indicate to the terminal whether the measurement gap configured in the configuration information is used for GNSS measurement. This other information may exist independently or may be combined with the above information in the configuration information. This application embodiment does not limit this.

[0070] Optionally, the gap-sharing strategy is used to indicate the proportion of the first measurement gap and the cell measurement gap in the gaps used for measurement. The cell measurement gap is used by the terminal to perform cell measurements, such as intra-frequency cell measurements or inter-frequency cell measurements.

[0071] For example, if co-frequency cell measurements or adjacent-frequency cell measurements account for 30% of the measurement interval, and the first measurement interval accounts for 70% of the measurement interval, then the delay of co-frequency cell measurements or adjacent-frequency cell measurements needs to be divided by 30% based on the base delay, and the delay of the first measurement interval needs to be divided by 70% based on the base delay. The base delay is the default delay specified for the measurement. The smaller its proportion within the measurement interval, the greater the required delay, in order to ensure that measurements that take longer to complete are performed first.

[0072] In some embodiments, some information in the above configuration information is predefined by the communication protocol. For example, the communication protocol predefines the above repetition period as including repetition period 1 and repetition period 2. When the terminal obtains the configuration information to determine the first measurement gap, it will randomly determine the repetition period to be used from repetition period 1 and repetition period 2, or the terminal will determine the repetition period to be used according to the needs of GNSS measurement, or the terminal will determine the repetition period to be used from the predefined repetition periods according to the instructions of the network. For the predefined methods and usage methods of other information in the configuration information, please refer to the above description of the repetition period, and this application embodiment will not repeat them. In some embodiments, when some information in the above configuration information is not indicated in the configuration information, the unindicated information has a predefined default value. Exemplarily, the gap type, gap identifier, and whether the gap is used for (or not used for) GNSS measurement can all be indicated explicitly or implicitly. For example, if the gap type is not indicated in the configuration information, the default type is to configure the measurement gap for each terminal. The gap identifier can also be determined without indication, based on information used to uniquely identify the terminal or predefined information.

[0073] In some embodiments, the first measurement gap is dedicated to GNSS measurements, meaning that within the first measurement gap, the terminal can only perform GNSS measurements.

[0074] Optionally, if the terminal requires a first measurement gap dedicated to GNSS measurements, the terminal sends a first indication to the network device. This first indication indicates that the terminal requires a first measurement gap dedicated to GNSS measurements. This causes the network device to configure the terminal with a first measurement gap dedicated to GNSS measurements. Optionally, this first measurement gap is configured based on a legacy measurement gap.

[0075] In some embodiments, the first measurement gap reuses the second measurement gap, which is used for measurements other than GNSS measurements. That is, within the first measurement gap, the terminal can perform not only GNSS measurements but also measurements other than GNSS measurements.

[0076] Optionally, the first measurement gap can reuse the second measurement gap only if a concurrent measurement gap is not configured in the second measurement gap. The concurrent measurement gap is used to perform measurements other than GNSS measurements concurrently with the second measurement gap. That is, the terminal will concurrently perform measurements other than GNSS measurements within the second measurement gap and within its concurrent measurement gaps.

[0077] In some embodiments, even without configuring a dedicated measurement gap for GNSS measurements, the terminal can still perform GNSS measurements using the gap configured in the measurement gap configuration (MeasGapConfig). Here, MeasGapConfig is a configuration parameter for gaps not used for GNSS measurements; it can be considered as existing measurement gap configuration parameters used for measurements other than GNSS measurements.

[0078] In some embodiments, the terminal is able to report capability information to the network device. In some embodiments, the capability information includes information indicating that the terminal needs to perform GNSS measurements through a first measurement gap. In some embodiments, the capability information includes information indicating that the terminal supports performing GNSS measurements through the first measurement gap. In some embodiments, the capability information includes both information indicating that the terminal needs to perform GNSS measurements through the first measurement gap and information indicating that the terminal supports performing GNSS measurements through the first measurement gap. Based on this capability information, the network device can configure a first measurement gap for GNSS measurements for the terminal.

[0079] For example, when the terminal reports either information indicating that it needs to perform GNSS measurements through the first measurement gap, or information indicating that it supports performing GNSS measurements through the first measurement gap, the network device configures the first measurement gap for GNSS measurements to the terminal. Alternatively, when the terminal reports information indicating that it supports performing GNSS measurements through the first measurement gap, the network device learns of the terminal's capabilities, and only configures the first measurement gap for GNSS measurements to the terminal when the terminal reports information indicating that it needs to perform GNSS measurements through the first measurement gap.

[0080] In some embodiments, the terminal spontaneously reports the aforementioned capability information to the network device. In other embodiments, the network device requests the reporting of the capability information from the terminal. That is, the terminal receives a request from the network device requesting the terminal to report the aforementioned capability information.

[0081] In some embodiments, the first instruction sent by the terminal to the network device and the capability information reported by the terminal to the network device are carried in the same message. In other embodiments, the first instruction sent by the terminal to the network device and the capability information reported by the terminal to the network device are carried in different messages. For example, the terminal first reports the capability information to the network device to instruct the network device to configure a first measurement gap for it, and then sends the first instruction to instruct the network device to configure a first measurement gap dedicated to GNSS measurements.

[0082] In some embodiments, when a terminal needs to perform GNSS measurements, but the terminal fails to acquire a first measurement gap or the first measurement gap is insufficient for the terminal to perform GNSS measurements (e.g., the duration of the first measurement gap is insufficient for the terminal to perform GNSS measurements), the terminal sends a third instruction to the network device. This third instruction indicates that the terminal needs to perform GNSS measurements. Based on this third instruction, the network device can configure a measurement gap for the terminal that meets its GNSS measurement requirements.

[0083] In some embodiments, when the terminal does not currently need to perform GNSS measurements, it can send a fourth indication to the network device. This fourth indication indicates that the terminal does not need to perform GNSS measurements. Based on this fourth indication, the network device can avoid configuring measurement intervals for GNSS measurements on the terminal, thereby saving power for the terminal.

[0084] For GNSS measurements: In some embodiments, when the first measurement gap and the second measurement gap overlap, the terminal determines, based on gap priority, whether to perform the measurement corresponding to the first measurement gap within the overlap, or to perform the measurement corresponding to the second measurement gap within the overlap. The second measurement gap is used for measurements other than GNSS measurements. This scheme ensures that the terminal performs higher-priority tasks within the overlap.

[0085] For example, the second measurement gap is a measurement gap configured for each terminal via Measurement Gap Configuration (MeasGapConfig), or a measurement gap configured for each carrier via Measurement Gap Configuration (MeasGapConfigPerCC), or a measurement gap configured for dense Positioning Reference Signals (PRS) via Measurement Gap Configuration (MeasGapConfigDensePRS).

[0086] In some embodiments, the priority of the first measurement gap can be configured via a network. In other embodiments, the system (communication protocol) specifies that the priority of the first measurement gap is higher or lower than the priority of other measurement gaps.

[0087] In some embodiments, when using network configuration, the configuration information of the first measurement gap sent by the network device to the terminal indicates the priority of the first measurement gap. In some embodiments, when using system convention, it is agreed that the priority of the first measurement gap is higher or lower than the priority of the measurement gap for co-frequency cell measurement or adjacent frequency cell measurement, and that the priority of the first measurement gap is higher or lower than the priority of the measurement gap for PRS measurement.

[0088] For GNSS measurements performed outside the first measurement gap: In some embodiments, the terminal is capable of performing GNSS measurements both within and outside the first measurement gap.

[0089] In some embodiments, when the first measurement gap is located after the failure time, the terminal performs GNSS measurements outside the first measurement gap. The failure time is the moment when the terminal's GNSS measurement results become invalid. That is, if there is no available measurement gap for GNSS measurements before the GNSS measurement results become invalid (outdated), the terminal can perform GNSS measurements outside the first measurement gap, thereby avoiding the problem of inaccurate positioning caused by the terminal's inability to perform GNSS measurements when the terminal's GNSS measurement results become invalid.

[0090] In some embodiments, if the terminal's GNSS measurement results have become invalid, the terminal can perform GNSS measurements outside the first measurement gap.

[0091] In some embodiments, the terminal spontaneously performs GNSS measurements outside the first measurement gap under the above circumstances, for example, the terminal's ability to perform GNSS measurements outside the first measurement gap is pre-configured in the terminal.

[0092] In some embodiments, whether the terminal is able to perform GNSS measurements outside the first measurement gap is indicated by the network device.

[0093] Optionally, the terminal receives a second instruction sent by the network device, which instructs the terminal to perform GNSS measurements outside the first measurement gap. That is, the terminal will only perform GNSS measurements outside the first measurement gap according to the above conditions if the network device instructs the terminal that it can perform GNSS measurements outside the first measurement gap.

[0094] For GNSS measurements and serving cell measurements: In some embodiments, the terminal performs serving cell measurements either after or before the first measurement interval ends. This approach avoids the problem of the terminal being unable to perform serving cell measurements in a timely manner due to GNSS measurements, resulting in prolonged communication interruptions with the serving cell and thus affecting the terminal's communication quality. The terminal's serving cell is the cell to which the terminal accesses or provides communication services.

[0095] In some embodiments, the terminal performs serving cell measurement either after or before the end of the first measurement gap, according to the instruction information. That is, the terminal will only perform serving cell measurement after or before the end of the first measurement gap when the network device instructs the terminal via the instruction information. Optionally, the instruction information can be carried in the configuration information of the first measurement gap, or it can be carried in other messages sent by the network device to the terminal; this application embodiment does not limit this.

[0096] In some embodiments, if the terminal does not perform serving cell measurement within the configured duration, the terminal will perform serving cell measurement either after the first measurement interval ends or before the first measurement interval ends. The configured duration is configured or predefined by the network device, for example, the configured duration is carried in the configuration information of the first measurement interval.

[0097] In some embodiments, if the terminal does not perform serving cell measurements within a configured number of times (N), the terminal will perform serving cell measurements either after the first measurement interval ends or before the first measurement interval ends. The configured number of times is configured or predefined by the network device, for example, the configured number is carried in the configuration information of the first measurement interval. The number of times the terminal needs to perform serving cell measurements is determined based on the time, frequency, period, etc., of the terminal's serving cell measurements.

[0098] By coordinating the timing of GNSS and serving cell measurements by the terminal through the instructions of the aforementioned network devices, the network devices can coordinate the actions performed by the terminal based on the actual situation (such as the service quality of the serving cell). This effectively avoids the problem of the terminal being unable to perform serving cell measurements in a timely manner due to GNSS measurements, resulting in prolonged communication interruption with the serving cell and thus affecting the terminal's communication quality.

[0099] In summary, the method provided in this embodiment obtains a first measurement gap for GNSS measurements through the terminal, thereby enabling the terminal to perform GNSS measurements within that first measurement gap. This first measurement gap can be set according to actual conditions, thus avoiding the problem of the terminal being unable to perform GNSS measurements when the terminal's GNSS measurement results are invalid.

[0100] Regarding the process of the terminal acquiring the first measurement gap: exist Figure 4 Based on the illustrated embodiments, optionally, the configuration information is obtained by the terminal through reception. In some embodiments, the terminal also needs to report its capability information before receiving the configuration information. The process of configuring the first measurement gap to the terminal is described through the following embodiments: Figure 5 A flowchart illustrating a communication method provided in one embodiment of this application is shown. This method can be applied to a terminal. In some embodiments, the method can be applied to... Figure 1-3 The terminal in the system shown. The method includes: Step 504: Report capability information.

[0101] In some embodiments, the capability information includes information indicating that the terminal needs to perform GNSS measurements through the first measurement gap. In some embodiments, the capability information includes information indicating that the terminal supports GNSS measurements through the first measurement gap. In some embodiments, the capability information includes both information indicating that the terminal needs to perform GNSS measurements through the first measurement gap and information indicating that the terminal supports GNSS measurements through the first measurement gap.

[0102] In some embodiments, the terminal reports the aforementioned capability information to the network device. In some embodiments, the terminal reports the aforementioned capability information to the network device spontaneously. In some embodiments, the capability information is requested to be reported by the network device from the terminal. In some embodiments, the terminal reports the capability information to other communication devices besides the network device; this application does not impose any restrictions on this.

[0103] Step 506: Receive configuration information, which is used to configure the first measurement gap.

[0104] The first measurement gap is used for GNSS measurement. After the terminal acquires the first measurement gap, it can perform GNSS measurement within the first measurement gap to obtain the GNSS measurement result.

[0105] For details regarding the configuration information, please refer to the description of the configuration information in step 402 above. This embodiment of the application will not repeat the details.

[0106] Optionally, the recipient of the capability information reported by the terminal may be the same as or different from the sender of the configuration information. In some embodiments, both the recipient of the capability information and the sender of the configuration information are network devices. In some embodiments, the recipient of the capability information is a communication device outside the network device, and the sender of the configuration information is the network device. Optionally, the communication device outside the network device may be a core network device or a terminal that communicates with the terminal via a side link, etc. After receiving the capability information reported by the terminal, the communication device outside the network device may forward it to the network device corresponding to the terminal, thereby instructing the network device to send the aforementioned configuration information to the terminal.

[0107] In some embodiments, the first measurement gap is dedicated to GNSS measurements. In some embodiments, the first measurement gap reuses a second measurement gap for measurements other than GNSS measurements.

[0108] In some embodiments, when a terminal needs to perform GNSS measurements, but the terminal has not obtained a first measurement gap or the first measurement gap is insufficient for the terminal to perform GNSS measurements, the terminal sends a third instruction to the network device. This third instruction indicates that the terminal needs to perform GNSS measurements. Based on this third instruction, the network device can configure a measurement gap for the terminal that meets its GNSS measurement requirements.

[0109] In some embodiments, when the terminal does not currently need to perform GNSS measurements, it can send a fourth indication to the network device. This fourth indication indicates that the terminal does not need to perform GNSS measurements. Based on this fourth indication, the network device can avoid configuring measurement intervals for GNSS measurements on the terminal, thereby saving power for the terminal.

[0110] It should be noted that the steps described above, in which the terminal sends the third and fourth instructions to the network device, can be implemented as a standalone embodiment, and can also be combined with other embodiments.

[0111] In some embodiments, the aforementioned capability information is reported by the terminal upon request. For example... Figure 6 As shown, in Figure 5 The illustrated embodiment further includes the following step 502: Step 502: Receive request information.

[0112] In some embodiments, the request information is sent from the network device to the terminal. In some embodiments, the request information is sent from a communication device other than the network device to the terminal, such as the core network device mentioned above or a terminal that communicates with the terminal via a side link. This application does not impose any restrictions on this.

[0113] This request information instructs the terminal to report capability information to the network device. After requesting the terminal to receive the reported capability information, the network device can configure a first measurement gap for the terminal. For details on how the network device configures the first measurement gap based on the capability information, please refer to [reference needed]. Figure 4 The relevant descriptions in the embodiments are not repeated in this application.

[0114] In summary, the method provided in this embodiment enables the terminal to perform GNSS measurements within a first measurement gap by configuring the terminal with such a gap. This first measurement gap can be set according to actual conditions, avoiding the problem of the terminal being unable to perform GNSS measurements when the terminal's GNSS measurement results are invalid. Furthermore, the method provided in this embodiment also enables the targeted configuration of the first measurement gap for terminals with corresponding capabilities. Additionally, the method provided in this embodiment also enables the configuration of the first measurement gap for terminals with corresponding capabilities by requesting the terminal's capabilities, thus achieving flexible configuration of the first measurement gap for the terminal.

[0115] It should be noted that the above embodiments in this application can be combined with other embodiments, steps in other embodiments, and subordinate steps in other embodiments, without contradiction. Furthermore, the order of the method steps provided in the embodiments of this application can be appropriately adjusted, and steps can be added or removed as needed.

[0116] The process of measuring at the terminal when there is an overlap in the measurement gaps: The method provided in this application, when there is an intersection between a first measurement gap and a second measurement gap configured for the terminal, enables the terminal to determine the priority of the task to be performed during the intersection period. This solution is illustrated by the following embodiments: Figure 7 A flowchart illustrating a communication method provided in one embodiment of this application is shown. This method can be applied to a terminal. In some embodiments, the method can be applied to... Figure 1-3 The terminal in the system shown. The method includes: Step 702: If there is an intersection between the first measurement gap and the second measurement gap, determine whether to perform the measurement corresponding to the first measurement gap in the intersection or the measurement corresponding to the second measurement gap in the intersection based on the gap priority.

[0117] The first measurement gap is the measurement gap acquired by the terminal for GNSS measurements. The process of the terminal acquiring the first measurement gap can be referred to... Figure 4 The relevant descriptions in the embodiments are not repeated in this application. The second measurement gap is used for measurements other than GNSS measurements. This scheme ensures that the terminal performs higher-priority tasks within the intersection.

[0118] For example, the second measurement gap is a measurement gap configured for each terminal via measurement gap configuration, or a measurement gap configured for each carrier via measurement gap configuration, or a measurement gap configured for dense PRS via measurement gap configuration.

[0119] In some embodiments, the priority of the first measurement gap can be configured via a network. In other embodiments, the system (communication protocol) specifies that the priority of the first measurement gap is higher or lower than the priority of other measurement gaps.

[0120] In some embodiments, when using network configuration, the configuration information of the first measurement gap sent by the network device to the terminal indicates the priority of the first measurement gap. In some embodiments, when using system convention, the priority of the first measurement gap is agreed to be higher or lower than the priority of measurement gaps for co-frequency cell measurement or adjacent frequency cell measurement, and the priority of the first measurement gap is agreed to be higher or lower than the priority of measurement gaps for PRS measurement.

[0121] In summary, the method provided in this embodiment allows the terminal to determine, based on priority, whether to perform the measurement corresponding to the first measurement gap at the intersection of the first and second measurement gaps, or to perform the measurement corresponding to the second measurement gap at the intersection. This ensures that the terminal executes higher-priority items at the intersection.

[0122] It should be noted that the steps in the above embodiments can be combined with other embodiments. For example, step 702 above can be combined with... Figure 4 , 5 All steps, some steps, and optional implementation methods provided in the embodiments shown in 6 can be combined to obtain new embodiments.

[0123] Regarding the process of performing GNSS measurements at the terminal outside the first measurement gap: The method provided in this application also allows the terminal to perform GNSS measurements outside the first measurement gap, thereby avoiding the problem of inaccurate positioning caused by the terminal's inability to perform GNSS measurements when the terminal's GNSS measurement results are invalid. This solution is described through the following embodiments: Figure 8 A flowchart illustrating a communication method provided in one embodiment of this application is shown. This method can be applied to a terminal. In some embodiments, the method can be applied to... Figure 1-3 The terminal in the system shown. The method includes: Step 804: Perform GNSS measurements outside the first measurement gap.

[0124] The first measurement gap is the measurement gap acquired by the terminal for GNSS measurements. The process of the terminal acquiring the first measurement gap can be referred to... Figure 4 The relevant descriptions in the embodiments are not repeated in this application.

[0125] In some embodiments, when the first measurement gap is located after the failure time, the terminal performs GNSS measurements outside the first measurement gap. The failure time is the moment when the terminal's GNSS measurement results become invalid. That is, if there is no available measurement gap for GNSS measurements before the GNSS measurement results become invalid (outdated), the terminal can perform GNSS measurements outside the first measurement gap, thereby avoiding the problem of inaccurate positioning caused by the terminal's inability to perform GNSS measurements when the terminal's GNSS measurement results become invalid.

[0126] In some embodiments, if the terminal's GNSS measurement results have become invalid, the terminal can perform GNSS measurements outside the first measurement gap.

[0127] In some embodiments, if the above conditions are met, the terminal can spontaneously perform GNSS measurements outside the first measurement gap.

[0128] In some embodiments, whether the terminal is capable of performing GNSS measurements outside the first measurement gap is determined by the terminal based on an instruction. For example... Figure 9 As shown, in Figure 8 The illustrated embodiment further includes the following step 802: Step 802: Receive the second instruction.

[0129] The second indication is used to indicate to the terminal that GNSS measurements are permitted outside the first measurement gap.

[0130] In some embodiments, the terminal receives a second instruction sent by the network device. That is, the terminal will only perform GNSS measurements outside the first measurement gap according to the conditions described in step 804 if the network device instructs the terminal that it can perform GNSS measurements outside the first measurement gap. In some embodiments, the terminal can also receive a second instruction sent by a communication device other than the network device; this application does not limit this.

[0131] In summary, the method provided in this embodiment, which allows the terminal to perform GNSS measurements outside the first measurement gap, can avoid the problem of inaccurate positioning caused by the terminal's inability to perform GNSS measurements when the terminal's GNSS measurement results are invalid.

[0132] It should be noted that the above embodiments in this application can be combined with other embodiments, steps in other embodiments, or subordinate steps in other embodiments, without contradiction. For example, step 804 above can be combined with... Figure 4 , 5 All steps, some steps, and optional implementation methods provided in the embodiments shown in 6 can be combined to obtain new embodiments.

[0133] GNSS measurements and serving cell measurements for the terminal: The method provided in this application also coordinates GNSS measurements performed by the terminal and serving cell measurements, thereby avoiding the problem that the terminal's communication quality is affected by the inability to perform serving cell measurements in a timely manner due to GNSS measurements, i.e., prolonged communication interruption with the serving cell. The following embodiments illustrate this solution: Figure 10 A flowchart illustrating a communication method provided in one embodiment of this application is shown. This method can be applied to a terminal. In some embodiments, the method can be applied to... Figure 1-3 The terminal in the system shown. The method includes: Step 1002: Before the end of the first measurement interval, the terminal performs serving cell measurement.

[0134] The first measurement gap is the measurement gap acquired by the terminal for GNSS measurements. The process of the terminal acquiring the first measurement gap can be referred to... Figure 4 The relevant descriptions in the embodiments are not repeated in this application.

[0135] In some embodiments, the terminal performs serving cell measurement before the end of the first measurement interval, which may include the terminal performing serving cell measurement during the first measurement interval. This scheme can avoid the problem of the terminal being unable to perform serving cell measurement in a timely manner due to GNSS measurement, which takes a long time, thus affecting the terminal's communication quality. The terminal's serving cell is the cell that the terminal accesses or that provides communication services to the terminal.

[0136] In some embodiments, the terminal performs serving cell measurement before the end of the first measurement interval, according to the indication information. Optionally, the indication information can be carried in the configuration information of the first measurement interval, or it can be carried in other messages sent by the network device to the terminal; this application embodiment does not limit this.

[0137] In some embodiments, if the terminal does not perform serving cell measurement within the configured duration, the terminal will perform serving cell measurement before the end of the first measurement interval. The configured duration is configured or predefined by the network device, for example, the configured duration is carried in the configuration information of the first measurement interval.

[0138] In some embodiments, if the terminal does not perform serving cell measurements within a configured number of times (N), the terminal will perform serving cell measurements before the end of the first measurement interval. The configured number of times is configured or predefined by the network device, for example, the configured number is carried in the configuration information of the first measurement interval. The number of times the terminal needs to perform serving cell measurements is determined based on the time, frequency, period, etc., of the terminal's serving cell measurements.

[0139] Figure 11 shows a flowchart of a communication method provided in one embodiment of this application. This method can be applied to a terminal. In some embodiments, the method can be applied to... Figure 1-3 The terminal in the system shown. The method includes: Step 1102: After the first measurement interval ends, the terminal performs serving cell measurement.

[0140] The first measurement gap is the measurement gap acquired by the terminal for GNSS measurements. The process of the terminal acquiring the first measurement gap can be referred to... Figure 4 The relevant descriptions in the embodiments are not repeated in this application.

[0141] After the first measurement interval ends, the terminal performs serving cell measurements. This ensures that the terminal has sufficient time to perform GNSS measurements during the first measurement interval, thereby improving the accuracy of the terminal's positioning. Simultaneously, triggering serving cell measurements after the first measurement interval avoids prolonged communication interruptions between the terminal and the serving cell, which could negatively impact the terminal's communication quality.

[0142] In some embodiments, the terminal performs serving cell measurement after the first measurement interval ends, according to the indication information. Optionally, the indication information can be carried in the configuration information of the first measurement interval, or it can be carried in other messages sent by the network device to the terminal; this application embodiment does not limit this.

[0143] In some embodiments, if the terminal does not perform serving cell measurement within the configured duration, the terminal will perform serving cell measurement after the first measurement interval ends. The configured duration is configured or predefined by the network device, for example, the configured duration is carried in the configuration information of the first measurement interval.

[0144] In some embodiments, if the terminal does not perform serving cell measurements within a configured number of times (N), the terminal will perform serving cell measurements after the first measurement interval ends. The configured number of times is configured or predefined by the network device, for example, the configured number is carried in the configuration information of the first measurement interval. The number of times the terminal needs to perform serving cell measurements is determined based on the time, frequency, period, etc., of the terminal's serving cell measurements.

[0145] In summary, the method provided in this embodiment, by coordinating GNSS measurements and serving cell measurements performed by the terminal, can avoid the problem of the terminal being unable to perform serving cell measurements in a timely manner due to GNSS measurements being performed by the terminal, thereby affecting the communication quality of the terminal.

[0146] It should be noted that the steps in the above embodiments can be combined with other embodiments. For example, steps 1002 or 1102 can be combined with... Figure 4 , 5 All steps, some steps, and optional implementation methods provided in the embodiments shown in 6 can be combined to obtain new embodiments.

[0147] Figure 12 A flowchart of a communication method according to an embodiment of this application is shown. This method can be applied to a network device. The method includes: Step 1206: Send configuration information to the terminal. The configuration information is used to configure the first measurement gap.

[0148] The first measurement gap is used for GNSS measurement. After the terminal acquires the first measurement gap, it can perform GNSS measurement within the first measurement gap to obtain the GNSS measurement result.

[0149] Configuration for the first measuring gap: In some embodiments, the network device configures the first measurement gap for the terminal by sending configuration information to the terminal, the configuration information indicating the first measurement gap. For details of the configuration information, please refer to the description of the configuration information in step 402 above; this embodiment will not repeat those details.

[0150] In some embodiments, the first measurement gap is dedicated to GNSS measurements, meaning that within the first measurement gap, the terminal can only perform GNSS measurements. In other embodiments, the first measurement gap reuses a second measurement gap, which is used for measurements other than GNSS measurements. That is, within the first measurement gap, the terminal can perform not only GNSS measurements but also measurements other than GNSS measurements.

[0151] In some embodiments, when the terminal requires a first measurement gap dedicated to GNSS measurements, the network device receives a first indication from the terminal. This first indication indicates that the terminal requires a first measurement gap dedicated to GNSS measurements. Based on this first indication, the network device can configure the terminal with a first measurement gap dedicated to GNSS measurements.

[0152] In some embodiments, the network device can receive capability information reported by the terminal. In some embodiments, the capability information includes information indicating that the terminal needs to perform GNSS measurements through a first measurement gap. In some embodiments, the capability information includes information indicating that the terminal supports GNSS measurements through the first measurement gap. In some embodiments, the capability information includes both information indicating that the terminal needs to perform GNSS measurements through the first measurement gap and information indicating that the terminal supports GNSS measurements through the first measurement gap. Based on this capability information, the network device can configure a first measurement gap for GNSS measurements for the terminal. The process of the network device configuring the first measurement gap for the terminal based on the capability information can be referred to... Figure 4 The relevant descriptions in the embodiments are not repeated in this application.

[0153] In some embodiments, the terminal spontaneously reports the aforementioned capability information to the network device. In other embodiments, the network device requests the capability information from the terminal. The network device sends a request message to the terminal, which requests the terminal to report the aforementioned capability information.

[0154] In some embodiments, the first instruction sent by the terminal to the network device and the capability information reported by the terminal to the network device are carried in the same message. In some embodiments, the first instruction sent by the terminal to the network device and the capability information reported by the terminal to the network device are carried in different messages.

[0155] In some embodiments, when a terminal needs to perform GNSS measurements, but the terminal has not obtained a first measurement gap or the first measurement gap is insufficient for the terminal to perform GNSS measurements, the network device receives a third instruction sent by the terminal. This third instruction indicates that the terminal needs to perform GNSS measurements. Based on this third instruction, the network device can configure a measurement gap for the terminal that meets its GNSS measurement requirements.

[0156] In some embodiments, when the terminal does not currently need to perform GNSS measurements, the network device can receive a fourth indication sent by the terminal. This fourth indication indicates that the terminal does not need to perform GNSS measurements. Based on this fourth indication, the network device can avoid configuring measurement intervals for GNSS measurements for the terminal, thereby achieving the purpose of saving terminal power.

[0157] For GNSS measurements performed outside the first measurement gap: In some embodiments, the network device is capable of sending a second instruction to the terminal. This second instruction instructs the terminal to allow GNSS measurements outside the first measurement gap. That is, the terminal is capable of performing GNSS measurements both within and outside the first measurement gap.

[0158] For GNSS measurements and serving cell measurements: In some embodiments, the first measurement gap is indicated by configuration information sent from the network device to the terminal. This configuration information also carries indication information, which instructs the terminal to perform serving cell measurements either after or before the first measurement gap ends. In some embodiments, the aforementioned indication information is carried in other messages sent from the network device to the terminal; this application does not limit this approach.

[0159] In some embodiments, the network device sends a configuration duration to the terminal. This configuration duration instructs the terminal to perform a serving cell measurement either after the first measurement interval ends or before the first measurement interval ends, if the terminal has not performed a serving cell measurement within the configured duration.

[0160] In some embodiments, the network device sends a configuration count to the terminal. This configuration count instructs the terminal to perform a serving cell measurement either after the first measurement interval ends or before the first measurement interval ends, if the terminal has not performed a serving cell measurement within the configured count.

[0161] In summary, the method provided in this embodiment enables the terminal to perform GNSS measurements within a first measurement gap by configuring the terminal with such a gap. This first measurement gap can be set according to actual conditions, thus avoiding the problem of the terminal being unable to perform GNSS measurements when the terminal's GNSS measurement results are invalid.

[0162] Regarding the process of configuring the first measurement gap to the terminal: In some embodiments, before sending configuration information to the terminal, the network device also needs to receive capability information reported by the terminal. The following embodiments illustrate the process by which the network device configures the first measurement gap to the terminal. Figure 13 A flowchart illustrating a communication method provided in one embodiment of this application is shown. This method can be applied to a network device. In some embodiments, the method can be applied to... Figure 1-3 The network devices in the system shown. For example... Figure 13 As shown, in Figure 12 The illustrated embodiment further includes the following step 1204: Step 1204: Receive capability information reported by the terminal.

[0163] For information on capabilities, please refer to [link / reference]. Figure 4 The relevant descriptions in the embodiments are not repeated in this application.

[0164] In some embodiments, the aforementioned capability information is requested by the network device from the terminal. For example... Figure 14 As shown, in Figure 13 The illustrated embodiment further includes the following step 1202: Step 1202: Send a request message to the terminal.

[0165] This request information is used to instruct the terminal to report capability information to the network device.

[0166] In summary, the method provided in this embodiment enables the terminal to perform GNSS measurements within a first measurement gap by configuring the terminal with such a gap. This first measurement gap can be set according to actual conditions, thus avoiding the problem of the terminal being unable to perform GNSS measurements when the terminal's GNSS measurement results are invalid.

[0167] It should be noted that the above embodiments in this application can be combined with other embodiments, steps in other embodiments, and subordinate steps in other embodiments, without contradiction. Furthermore, the order of the method steps provided in the embodiments of this application can be appropriately adjusted, and steps can be added or removed as needed.

[0168] Regarding the process of network equipment instructing the terminal to perform GNSS measurements outside the first measurement gap: Figure 15 shows a flowchart of a communication method provided in one embodiment of this application. This method can be applied to network devices. In some embodiments, the method can be applied to... Figure 1-3 The network device in the system shown. The method includes: Step 1502: Send a second instruction to the terminal.

[0169] The second indication is used to instruct the terminal to perform GNSS measurements outside the first measurement gap. That is, the terminal will only perform GNSS measurements outside the first measurement gap according to the above conditions if the network device instructs the terminal to perform GNSS measurements outside the first measurement gap.

[0170] For the specific implementation process of the terminal performing GNSS measurements outside the first measurement gap, please refer to the aforementioned... Figure 4 The embodiments described herein will not be elaborated upon further.

[0171] In summary, the method provided in this embodiment, which allows the terminal to perform GNSS measurements outside the first measurement gap, can avoid the problem of inaccurate positioning caused by the terminal's inability to perform GNSS measurements when the terminal's GNSS measurement results are invalid.

[0172] It should be noted that the steps in the above embodiments can be combined with other embodiments. For example, step 1502 can be combined with... Figure 12 , 13 All steps, some steps, and optional implementation methods provided in the embodiments shown in 14 are combined to obtain new embodiments.

[0173] The following illustrates a communication method provided by an embodiment of this application: In one alternative approach, the network (network device) sends GNSS measurement gap configuration information to the UE, and the UE uses the configured measurement gap to perform GNSS measurements.

[0174] In one alternative approach, the measurement gap configuration information includes at least one of the following: starting SFN and subframe, repetition period, offset, gap length, gap timing advance, gap type (e.g., per UE gap, or per FR1 gap), gap ID, gap priority, whether it is used for GNSS measurements, and gap sharing strategy.

[0175] Optionally, the gap type, gap ID, and whether it is used for GNSS measurements can be explicitly or implicitly indicated. For example, if the gap type is not indicated, it defaults to per UE. The gap ID does not need to be indicated.

[0176] In one alternative approach, the gap-sharing strategy includes indicating the proportion of measurement gaps used for intra / inter frequency cell measurements versus GNSS measurements.

[0177] For example, if co-frequency cell measurements or adjacent-frequency cell measurements account for 30% and GNSS measurements account for 70%, then the delay of co-frequency cell measurements or adjacent-frequency cell measurements needs to be divided by 30% based on the base delay, and the delay of GNSS measurements needs to be divided by 70% based on the base delay.

[0178] In one alternative approach, the GNSS measurement gap can be a measurement gap specifically configured for GNSS measurements, or a configuration that reuses other measurement gaps.

[0179] In one alternative approach, GNSS measurement gaps can reuse other measurement gaps.

[0180] In an optional approach, if no dedicated GNSS measurement gap is configured, the measurement gap configuration (MeasGapConfig) is used. This measurement gap configuration uses the existing measurement gap (for cell measurements) configuration parameters.

[0181] In one alternative approach, the UE can indicate to the network whether a dedicated GNSS measurement gap is required for GNSS measurements.

[0182] In one alternative approach, the network only allows the configuration of GNSS measurement gaps to reuse measurement gaps configured elsewhere when no concurrent measurement gap is configured.

[0183] In one alternative approach, the UE reports its own network capability information, indicating whether GNSS measurements are required during measurement gaps.

[0184] In one alternative approach, the network can request the UE to report its need for the ability to perform GNSS measurements through measurement gaps. Upon receiving the request, the UE reports whether it needs the ability to perform GNSS measurements through measurement gaps.

[0185] In one alternative approach, the UE reports its own network capability information, indicating whether it supports GNSS measurements through measurement gaps.

[0186] In one alternative approach, if no measurement gap is available for GNSS measurement before the GNSS timeout / outdated, the UE can perform GNSS measurements outside the measurement gap in order to acquire GNSS.

[0187] In one alternative approach, the network sends configuration information to indicate whether the UE allows GNSS measurements outside the measurement gap.

[0188] In one optional approach, GNSS measurement gaps can be configured simultaneously with other measurement gaps. If the two overlap in time, the UE determines whether to use the GNSS measurement gap or another measurement gap based on priority during the overlapping time.

[0189] Examples of other measurement gaps include per-UE configured measurement gap configurations (MeasGapConfig), per-carrier configured measurement gap configurations (MeasGapConfigPerCC), or dense PRS measurement gap configurations (MeasGapConfigDensePRS) configured for dense PRS measurements. The priority of GNSS measurement gaps can be configured by the network or by system conventions, where the priority of GNSS measurement gaps is higher or lower than the priority of other measurement gaps. For example, the priority of GNSS measurement gaps may be higher / lower than the priority of measurement gaps for co-channel or adjacent-channel cells; or the priority of GNSS measurement gaps may be higher / lower than the priority of measurement gaps for PRS measurements.

[0190] In an alternative approach, if the UE GNSS timeout occurs, the UE can perform GNSS measurements outside the measurement interval.

[0191] In one alternative approach, if the UE currently needs to perform GNSS measurements, but the network has not configured a measurement gap for GNSS measurements or the configured measurement gap is insufficient for GNSS measurements, the UE sends an indication message to the network to indicate that GNSS measurements are required.

[0192] In one alternative approach, if the UE does not currently require GNSS measurements, the UE sends an indication message to the network to indicate that GNSS measurements are not required.

[0193] In one alternative approach, the UE performs serving cell measurements either after the GNSS measurement gap ends or before the GNSS measurement gap ends.

[0194] In one alternative approach, the network indicates in the measurement gap configuration whether the UE needs to perform serving cell measurements after or before the end of the GNSS measurement gap.

[0195] In one alternative approach, if the UE does not perform serving cell measurements for a period of time, it will perform serving cell measurements either after the GNSS measurement interval ends or before the GNSS measurement interval ends. The timing is configured by the base station or agreed upon by the system.

[0196] In one optional approach, if the UE fails to perform serving cell measurements N consecutive times, it will perform serving cell measurements either after the GNSS measurement interval ends or before the GNSS measurement interval ends. The number N is configured by the base station or agreed upon by the system.
