[0047] First, some technical knowledge related to the present disclosure is introduced and described:

[0048] NTN technology

[0049] Currently, the relevant standard organizations are studying NTN technology, which generally adopts satellite communication to provide communication services to ground users. Compared with the ground cellular communication network, satellite communication has many unique advantages. First, satellite communication is not limited by the user's region. For example, general land communication cannot cover oceans, mountains, deserts, and other areas where communication equipment cannot be set up or where communication coverage is not provided due to sparse population. For satellite communication, a satellite can cover a large area of the ground, and the satellite can orbit the earth, so theoretically every corner of the earth can be covered by satellite communication. Second, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor countries or regions at a low cost, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting the development of these areas. Third, satellite communication is far away, and the cost of communication does not increase significantly as the communication distance increases. Finally, satellite communication is stable and is not limited by natural disasters.

[0050] Communication satellites are divided into LEO (Low-Earth Orbit), MEO (Medium-Earth Orbit), GEO (Geostationary Earth Orbit), HEO (High Elliptical Orbit) and the like according to the orbital height. At the current stage, the main research is LEO and GEO.

[0051] 1、LEO

[0052] Low-orbit satellites have a height range of 500km-1500km, and the corresponding orbital period is about 1.5 hours-2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmit power requirement of the user terminal device is not high.

[0053] 2、GEO

[0054] GEO (Geostationary Earth Orbit) satellites have an orbital height of 35786km and a rotation period of 24 hours around the earth. The signal propagation delay of single-hop communication between users is generally 250ms.

[0055] In order to ensure the coverage of the satellite and improve the system capacity of the entire satellite communication system, the satellite adopts multi-beam coverage of the ground, and a satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of dozens to hundreds of kilometers.

[0056] The satellite altitude, orbit, satellite coverage range of a typical NTN network are given in Table 1:

[0057] Table 1

[0058]

[0059]

[0060] The IoT terminal device includes at least one of a BL UE (Bandwidth reduction and Low complexity UE), a UE in CE mode (UE in Coverage Enhancement mode), and a NB-IOT UE (Narrow Band Internet of Things UE).

[0061] Embodiments of the present disclosure can be applied in an NTN system, as shown in Figure 1 and Figure 2 .

[0062] Please refer to Figure 1 , which shows a schematic diagram of an NTN system, where the communication satellite in the NTN system is a transparent payload satellite, where transparent means direct forwarding without modulation and demodulation or other intermediate processing. As shown in Figure 1 , the NTN system includes a terminal device 10, a satellite 20, an NTN gateway 30, an access network device 40, and a core network device 50.

[0063] The terminal device 10 and the access network device 40 can communicate through an air interface (such as a Uu interface). In the architecture shown in Figure 1 , the access network device 40 can be deployed on the ground, and the uplink and downlink communication between the terminal device 10 and the access network device 40 can be relayed through the satellite 20 and the NTN gateway 30 (usually located on the ground). Taking uplink transmission as an example, the terminal device 10 sends uplink signals to the satellite 20, the satellite 20 forwards the uplink signals to the NTN gateway 30, and the NTN gateway 30 forwards the uplink signals to the access network device 40, and the access network device 40 sends the uplink signals to the core network device 50. Taking downlink transmission as an example, the downlink signals from the core network device 50 are sent to the access network device 40, the access network device 40 sends the downlink signals to the NTN gateway 30, the NTN gateway 30 forwards the downlink signals to the satellite 20, and the satellite 20 forwards the downlink signals to the terminal device 10.

[0064] In this NTN system, satellite 20 has the role of frequency conversion and signal amplification, satellite 20 does not demodulate the signal of access network device 40, satellite 20 is similar to a repeater.

[0065] Please refer to Figure 2 which shows a schematic diagram of another NTN system, in which the communication satellite is a regenerative payload satellite. As shown in Figure 2 , the NTN system includes: terminal device 10, satellite 20, NTN gateway 30 and core network device 50.

[0066] In the Figure 2 shown architecture, the function set of access network device 40 is integrated on satellite 20, that is, satellite 20 has the function of access network device 40. Terminal device 10 and satellite 20 can communicate through the air interface (such as Uu interface). Satellite 20 and NTN gateway 30 (usually located on the ground) can communicate through SRI (Satellite Radio Interface, Satellite Radio Interface). In this NTN system, the satellite receives the signal and demodulates and decodes it, and then re-encodes and modulates it, and transmits the regenerated signal through the satellite frequency band.

[0067] In the Figure 2 shown architecture, taking uplink transmission as an example, terminal device 10 sends uplink signal to satellite 20, satellite 20 forwards the above-mentioned uplink signal to NTN gateway 30, and NTN gateway 30 sends the above-mentioned uplink signal to core network device 50. Taking downlink transmission as an example, downlink signal from core network device 50 is sent to NTN gateway 30, NTN gateway 30 forwards the above-mentioned downlink signal to satellite 20, and satellite 20 forwards the above-mentioned downlink signal to terminal device 10.

[0068] In the above Figure 1 and Figure 2 shown network architecture, access network device 40 is a device for providing wireless communication services for terminal device 10. Access network device 40 and terminal device 10 can establish a connection, so as to communicate through the connection, including the interaction of signaling and data. The number of access network devices 40 can be multiple, and two adjacent access network devices 40 can also communicate through wired or wireless means. Terminal device 10 can switch between different access network devices 40, that is, establish a connection with different access network devices 40.

[0069] Taking a cellular communication network as an example, the access network device 40 in the cellular communication network can be a base station. The base station is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The base station can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with base station functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As the communication technology evolves, the name of the "base station" can change. For ease of description, in the embodiments of the present disclosure, the devices described above that provide wireless communication functions for the terminal device 10 are collectively referred to as base stations or access network devices.

[0070] In addition, the terminal device 10 involved in the embodiments of the present disclosure can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to wireless modems, as well as various forms of UE (User Equipment), MS (Mobile Station), terminal device, and the like. For ease of description, in the embodiments of the present disclosure, the above-mentioned devices are collectively referred to as terminal devices. In the embodiments of the present disclosure, "UE" is used to represent "terminal device" in some places. In the embodiments of the present disclosure, the "network device" can be an access network device (such as a base station) or a satellite.

[0071] In addition, taking a 5G NTN system as an example, multiple satellites 20 can be included in the NTN system. A satellite 20 can cover a certain range of ground area and provide wireless communication services for terminal devices 10 on the ground area. In addition, the satellite 20 can make an orbital motion around the earth, and by deploying multiple satellites 20, communication coverage of different areas on the earth's surface can be achieved.

[0072] In addition, in the embodiments of the present disclosure, the nouns "network" and "system" are often used interchangeably, but those skilled in the art can understand their meanings. The technical solutions described in the embodiments of the present disclosure can be applicable to LTE systems, 5G systems, 5G NR systems, subsequent evolution systems, or other communication systems, and the present disclosure does not limit this.

[0073] For some IOT terminals, it is not possible to support simultaneous GNSS reception and LTE transmission, and the validity of the GNSS positioning obtained by the terminal can only be maintained for a period of time. After exceeding this time, the GNSS positioning corresponding to the terminal is invalid, and the terminal needs to reacquire the GNSS positioning. Therefore, the embodiments of the present disclosure provide a way for a terminal device to receive GNSS measurement gap configuration information, and then perform GNSS measurement based on the GNSS measurement gap.

[0074] Please refer toFigure 3 FIG. 1 shows a flowchart of a GNSS measurement method provided by an embodiment of the present disclosure. The embodiment is exemplarily illustrated by a terminal device in a communication system as shown in FIG. 1. The method can include the following steps: Figure 1 or Figure 2 The method can include the following steps:

[0075] Step 301: receiving configuration information.

[0076] The configuration information is used to indicate a GNSS measurement gap, and the configuration information is sent by a network device (such as an access network device or a satellite) to the terminal. In some embodiments, the configuration information is pre-configured by the network device.

[0077] In some embodiments, the GNSS measurement gap is a time window for the terminal to perform GNSS measurement. That is, the terminal performs GNSS measurement based on the GNSS measurement gap.

[0078] Exemplarily, before step 301, the terminal device can obtain a GNSS position fix, and the GNSS position fix has a validity period. In the case where the validity period of the GNSS position fix ends, it is determined that the GNSS position fix is outdated.

[0079] It should be understood that the validity period of the GNSS position fix can be pre-configured by a GNSS system or agreed by a protocol, and the present disclosure does not limit this. Exemplarily, the terminal device obtains the validity period of the GNSS from a GPS (Global Positioning System) module.

[0080] In the case where the terminal needs to perform GNSS measurement, such as before the GNSS position fix is invalid to obtain a latest GNSS position fix, or after the GNSS position fix is invalid to re-obtain a GNSS position fix, the terminal can determine the GNSS measurement gap based on the configuration information, and perform GNSS measurement in the time window corresponding to the GNSS measurement gap.

[0081] In some embodiments, the configuration information includes at least one of the following parameters:

[0082] • SFN (System Frame Number) and subframe of the measurement gap;

[0083] • repetition period of the measurement gap;

[0084] • offset parameter of the measurement gap;

[0085] • gap length of the measurement gap;

[0086] • a timing advance of the measurement gap;

[0087] • a gap type of the measurement gap;

[0088] • a gap ID of the measurement gap;

[0089] • a gap priority of the measurement gap;

[0090] • configuration indication information of the measurement gap.

[0091] Wherein, the repetition period of the measurement gap is used to indicate that the measurement gap repeats according to a specified period length, the offset parameter of the measurement gap is used to indicate that the measurement gap is offset from the SFM by a specified number of subframes, the gap length of the measurement gap is used to indicate the time length of the time window in which the measurement can be performed, the timing advance of the measurement gap is used to compensate for the transmission delay of the configuration information, the gap type of the measurement gap includes at least one of a per UE gap, a per FR1 gap, and a per FR2 gap, wherein FR1 (Frequency range 1) and FR2 (Frequency range 2) are two frequency ranges specified by 5G NR respectively, the gap ID is used to indicate different measurement gaps, the gap priority of the measurement gap is used to indicate the adoption order between multiple measurement gaps, in some embodiments, the multiple measurement gaps include a dedicated GNSS measurement gap configured for GNSS measurement and a measurement gap multiplexing GNSS measurement and other measurements, optionally, the measurement gap dedicated for GNSS measurement is preferentially used for GNSS measurement, and in the case that the measurement gap dedicated for GNSS measurement cannot be used, the measurement gap multiplexing GNSS measurement and other measurements is used for GNSS measurement, in another embodiment, the multiple measurement gaps include a GNSS measurement gap and other measurement gaps, such as a reference signal measurement gap, optionally, the priority of the GNSS measurement gap is higher than that of the reference signal measurement gap, and then the GNSS measurement gap is preferentially used for GNSS measurement. The configuration indication information of the measurement gap is used to indicate whether the measurement gap is a measurement gap corresponding to the configuration information pre-configured by the network device.

[0092] It should be understood that the above-mentioned parameters can be pre-configured by the network device or agreed by the protocol, and the present disclosure does not limit this.

[0093] In some embodiments, the above-mentioned GNSS measurement gap can be a measurement gap dedicated for GNSS measurement, or a measurement gap multiplexing GNSS measurement and other measurements, such as a measurement gap multiplexing base station measurement in a serving cell signal scenario for GNSS measurement.

[0094] After receiving the configuration information, the terminal can perform GNSS measurement based on the GNSS measurement gap indicated by the configuration information, i.e., performing GNSS measurement in the time window corresponding to the GNSS measurement gap, wherein the GNSS measurement gap includes the following two states:

[0095] · an activated state;

[0096] · a deactivated state.

[0097] The activated state is used to instruct the terminal to perform GNSS measurement using the activated GNSS measurement gap; the deactivated state is used to instruct the terminal to stop GNSS measurement in the case that the terminal performs GNSS measurement using the activated GNSS measurement gap.

[0098] In some embodiments, in response to the GNSS measurement gap being activated, the terminal performs GNSS measurement using the GNSS measurement gap; in response to the GNSS measurement gap being deactivated, the terminal stops GNSS measurement.

[0099] In summary, the technical solution provided by the present embodiment provides a solution for the configuration of the GNSS measurement gap. The terminal receives the configuration information sent by the network device to indicate the GNSS measurement gap, so that the terminal can perform GNSS measurement based on the GNSS measurement gap.

[0100] For example, in response to the GNSS measurement gap being activated, GNSS measurement is performed using the GNSS measurement gap.

[0101] In some embodiments, before performing GNSS measurement using the GNSS measurement gap, the terminal needs to activate the GNSS measurement gap. Optionally, the case that the terminal activates the GNSS measurement gap includes at least one of the following cases:

[0102] First, the terminal activates the GNSS measurement gap based on the indication of the network device;

[0103] Second, the terminal actively activates the GNSS measurement gap.

[0104] First, the case that the terminal activates the GNSS measurement gap based on the indication of the network device is described.

[0105] Please refer to Figure 4 , Figure 4 is a flowchart of a GNSS measurement method provided by one embodiment of the present disclosure. The present embodiment takes the terminal device in the communication system shown in Figure 1 or Figure 2 as an example. The method can include the following steps:

[0106] Step 401, receiving first indication information.

[0107] The first indication information is used to indicate activation of a GNSS measurement gap, and the first indication information is sent by a network device, such as an access network device or a satellite, to a terminal. After receiving the first indication information, the terminal can activate the GNSS measurement gap based on the first indication information. The GNSS measurement gap can be a measurement gap indicated in the first indication information, or can be a pre-configured measurement gap.

[0108] In some embodiments, the first indication information is used to indicate activation of a GNSS measurement gap, or the first indication information is used to instruct the terminal to perform GNSS measurement, that is, the first indication information can directly instruct the terminal to activate the GNSS measurement gap, or can instruct the terminal to perform GNSS measurement to make the terminal activate the GNSS measurement gap.

[0109] Optionally, the first indication information can be RRC (Radio Resource Control protocol) signaling, or MAC CE (Media Access Control Control Element), or DCI (Downlink Control Information).

[0110] In some embodiments, the first indication information includes at least one of the following information fields:

[0111] The first information field is used to indicate activation of a GNSS measurement gap, that is, the network device directly instructs the terminal to activate the GNSS measurement gap, and the terminal can directly activate the GNSS measurement gap based on the first information field after receiving the first indication information.

[0112] Optionally, the first information field is used to instruct the terminal to switch a pre-configured GNSS measurement gap to an activated state, so as to perform GNSS measurement based on the activated GNSS measurement gap; or the first information field is used to indicate a GNSS measurement gap that needs to be activated, so that the terminal performs GNSS measurement based on the GNSS measurement gap indicated by the first information field.

[0113] The second information field is used to instruct the terminal to perform GNSS measurement, that is, the network device instructs the terminal to perform GNSS measurement, and the terminal activates the GNSS measurement gap based on the requirement of GNSS measurement indicated by the second information field. Optionally, the second information field is used to instruct the terminal to start a GNSS measurement process.

[0114] In some embodiments, the first indication information can be sent by the network device to the terminal actively, or can be sent by the network device based on an activation request of the terminal.

[0115] In the case that the first indication information is sent by the network device based on the activation request of the terminal, the terminal sends an activation request to the network device before receiving the first indication information. The activation request is used to request to activate the GNSS measurement gap.

[0116] For example, the terminal sends the activation request to the network device by sending an UL MAC CE (UpLink Media Access Control Control Element) to the network device, wherein the UL MAC CE includes the activation request.

[0117] Secondly, the case that the terminal actively activates the GNSS measurement gap is described.

[0118] For reference Figure 5 , Figure 5 is a flowchart of a GNSS measurement method provided by one embodiment of the present disclosure. The embodiment takes the terminal device in the communication system shown in Figure 1 or Figure 2 as an example to illustrate the method. The method can include the following steps:

[0119] Step 501, in the case that the terminal meets the GNSS measurement condition, activate the GNSS measurement gap.

[0120] The GNSS measurement condition includes at least one of the following:

[0121] The current time exceeds the GNSS positioning validity period;

[0122] The remaining time length of the current GNSS positioning validity period is less than a threshold time length;

[0123] The number of GNSS measurement gaps before the current GNSS positioning expires is less than a threshold number.

[0124] The current time exceeds the GNSS positioning validity period, that is, the GNSS positioning is invalid; that is, the termination time of the validity period of the latest GNSS positioning in the historical time is before the current time.

[0125] In some embodiments, the threshold time length is determined based on the time length corresponding to the GNSS measurement gap required for GNSS measurement before the GNSS positioning expires.

[0126] In some embodiments, the threshold quantity is determined based on a quantity of GNSS measurement gaps required for GNSS measurement before expiration of the current GNSS positioning.

[0127] The remaining duration of the current GNSS positioning is less than the threshold duration, for example, the threshold duration is 1 ms, and the remaining duration of the current GNSS positioning is less than 1 ms, the GNSS measurement condition is met.

[0128] Optionally, the threshold duration is pre-configured, or the threshold duration is predefined, that is, the threshold duration can be configured by the network device or agreed by the protocol.

[0129] The quantity of GNSS measurement gaps before expiration of the current GNSS positioning is less than the threshold quantity, for example, 3 GNSS measurement gaps are required for GNSS measurement before expiration of the current GNSS positioning, and the quantity of GNSS measurement gaps before expiration of the current GNSS positioning is 0.

[0130] Optionally, the threshold quantity is pre-configured, or the threshold quantity is predefined, that is, the threshold quantity can be configured by the network device or agreed by the protocol.

[0131] In some embodiments, before step 501, the terminal receives second indication information, wherein the second indication information is used to indicate that the terminal has the right to activate the GNSS measurement gap, and the second indication information is sent by the network device.

[0132] For example, in the case that the terminal meets the GNSS measurement condition, before the GNSS measurement gap is activated, the network device grants the terminal the right to activate the GNSS measurement gap, and the terminal receives the second indication information, which indicates that the terminal has the right to actively activate the GNSS measurement gap.

[0133] Optionally, the second indication information can be RRC signaling, or MAC CE, or DCI.

[0134] In some embodiments, the second indication information can include an information field used to indicate that the terminal has the right to activate the GNSS measurement gap.

[0135] In summary, the method provided by the embodiment achieves the activation of the GNSS measurement gap based on the indication of the network device by receiving the first indication information, and achieves the active activation of the GNSS measurement gap by the terminal by activating the GNSS measurement gap in the case that the terminal meets the GNSS measurement condition, so that the terminal can activate the GNSS measurement gap in different situations, thereby responding to the activation of the GNSS measurement gap and using the GNSS measurement gap for GNSS measurement.

[0136] For example, in response to the GNSS measurement gap being de-activated, the terminal stops the GNSS measurement.

[0137] In some embodiments, before stopping the GNSS measurement, the terminal needs to de-activate the GNSS measurement gap.

[0138] Optionally, the case in which the terminal de-activates the GNSS measurement gap includes at least one of the following cases:

[0139] First, the terminal de-activates the GNSS measurement gap based on an indication of the network device;

[0140] Second, the terminal de-activates the GNSS measurement gap proactively.

[0141] First, the case in which the terminal de-activates the GNSS measurement gap based on an indication of the network device is described.

[0142] Please refer to Figure 6 , Figure 6 is a flowchart of a GNSS measurement method provided by one embodiment of the present disclosure. The present embodiment takes the terminal device in the communication system shown in Figure 1 or Figure 2 as an example for illustration. The method can include the following steps:

[0143] Step 601, receiving third indication information.

[0144] The third indication information is used to indicate de-activation of the GNSS measurement gap.

[0145] In some embodiments, the third indication information is used to indicate de-activation of the GNSS measurement gap, or the third indication information is used to indicate that the terminal stops the GNSS measurement, i.e., the third indication information can directly indicate that the terminal de-activates the GNSS measurement gap, or can make the terminal de-activate the GNSS measurement gap by indicating that the terminal stops the GNSS measurement.

[0146] Optionally, the third indication information can be RRC signaling, or MAC CE, or DCI.

[0147] In some embodiments, the third indication information includes at least one of the following information fields:

[0148] • The third information field is used to indicate de-activation of the GNSS measurement gap, i.e., the network device directly indicates that the terminal de-activates the GNSS measurement gap, and after receiving the third indication information, the terminal can directly de-activate the GNSS measurement gap based on the third information field.

[0149] Optionally, the third information field is used to instruct the terminal to switch the pre-configured GNSS measurement gap to an inactivated state, so as to stop GNSS measurement based on the inactivated GNSS measurement gap; or the third information field is used to instruct the GNSS measurement gap to be inactivated, so that the terminal stops GNSS measurement based on the inactivated GNSS measurement gap instructed by the third information field.

[0150] The fourth information field is used to instruct the terminal to stop GNSS measurement, i.e., the network device instructs the terminal to stop GNSS measurement, and the terminal inactivates the GNSS measurement gap based on the instruction of the fourth information field to stop GNSS measurement. Optionally, the fourth information field is used to instruct the terminal to stop the GNSS measurement process.

[0151] In some embodiments, the third instruction information can be sent by the network device to the terminal actively, or can be sent by the network device based on the deactivation request of the terminal.

[0152] In the case where the third instruction information is sent by the network device based on the deactivation request of the terminal, the terminal sends the deactivation request to the network device before receiving the third instruction information. The deactivation request is used to request the deactivation of the GNSS measurement gap.

[0153] For example, the terminal sends the deactivation request to the network device by sending uplink medium access control layer control signaling to the network device, wherein the deactivation request is included in the uplink medium access control layer control signaling.

[0154] Secondly, the case where the terminal actively deactivates the GNSS measurement gap is described.

[0155] Please refer to Figure 7 , Figure 7 is a flowchart of a GNSS measurement method provided by one embodiment of the present disclosure. The present embodiment takes the method as an example applied to the terminal device in the communication system as shown in Figure 1 or Figure 2 . As shown in Figure 7 , the terminal actively deactivates the GNSS measurement gap, which can include the following steps:

[0156] Step 701: In response to the completion of GNSS measurement by the terminal, the GNSS measurement gap is deactivated.

[0157] Step 702: In response to the absence of GNSS measurement demand by the terminal, the GNSS measurement gap is deactivated.

[0158] Exemplarily, the terminal not having the GNSS measurement requirement is implemented as at least one of the following cases: a current time does not exceed a GNSS positioning validity period; a remaining time length of the current GNSS positioning validity period is greater than a threshold time length; and a number of GNSS measurement gaps before the current GNSS positioning expires is greater than a threshold number.

[0159] It should be understood that the above cases in which the terminal does not have the GNSS measurement requirement are only exemplarily taken, and the present disclosure is not limited thereto.

[0160] The steps 701 and 702 are in parallel, i.e., the steps 701 and 702 are two cases in which the terminal actively deactivates the GNSS measurement gap, respectively.

[0161] In some embodiments, before the step 701 or the step 702, the terminal receives fourth indication information, where the fourth indication information is used to indicate that the terminal has the right to deactivate the GNSS measurement gap, and the fourth indication information is sent by the network device.

[0162] Exemplarily, before the terminal deactivates the GNSS measurement gap, the network device grants the terminal the right to deactivate the GNSS measurement gap, and the terminal receives the fourth indication information, where the fourth indication information indicates that the terminal has the right to actively deactivate the GNSS measurement gap.

[0163] Optionally, the fourth indication information can be RRC signaling, or MAC CE, or DCI.

[0164] In some embodiments, the fourth indication information can include an information field used to indicate that the terminal has the right to deactivate the GNSS measurement gap.

[0165] In summary, the method provided by the present embodiment achieves the deactivation of the GNSS measurement gap based on the indication of the network device by receiving the third indication information, and achieves the active deactivation of the GNSS measurement gap by the terminal by responding to the completion of the GNSS measurement by the terminal or responding to the terminal not having the GNSS measurement requirement, so that the terminal can deactivate the GNSS measurement gap in different cases, thereby stopping the GNSS measurement in response to the GNSS measurement gap being deactivated.

[0166] In some embodiments, in the process of executing the above GNSS measurement method on the terminal side, the terminal further reports, to the network device, a capability of the terminal to perform GNSS measurement based on the GNSS measurement gap.

[0167] Exemplarily, the terminal sends capability indication information to the network device, where the capability indication information is used to indicate the capability of the terminal to perform GNSS measurement based on the GNSS measurement gap, i.e., to inform the network device whether the terminal can perform GNSS measurement.

[0168] In some embodiments, the capability indication information is used to indicate the capability of the terminal to activate and deactivate the GNSS measurement gap based on the configuration of the network device, or the capability indication information is used to indicate the capability of the terminal to activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement.

[0169] In some embodiments, the capability of the terminal to activate and deactivate the GNSS measurement gap based on the configuration of the network device and the capability of the terminal to activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement can be indicated by one piece of capability indication information, or the capability of the terminal to activate and deactivate the GNSS measurement gap based on the configuration of the network device and the capability of the terminal to activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement can be indicated by multiple pieces of capability indication information.

[0170] In some embodiments, the capability indication information includes a fifth information field, wherein the fifth information field is used to indicate the capability of the terminal to activate and deactivate the GNSS measurement gap based on the configuration of the network device, i.e., to inform the network device whether the terminal can activate and deactivate the GNSS measurement gap based on the indication of the network device.

[0171] For example, a terminal sends capability indication information to a network device to inform the network device that the terminal can perform GNSS measurement, and the capability indication information includes a fifth information field to inform the network device that the terminal can activate and deactivate the GNSS measurement gap based on the indication of the network device, i.e., the terminal can activate the GNSS measurement gap after receiving a second indication information and deactivate the GNSS measurement gap after receiving a third indication information.

[0172] In some embodiments, the capability indication information includes a sixth information field, wherein the sixth information field is used to indicate the capability of the terminal to activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement, i.e., to inform the network device whether the terminal can activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement.

[0173] For example, a terminal sends capability indication information to a network device to inform the network device that the terminal can perform GNSS measurement, and the capability indication information includes a sixth information field to inform the network device that the terminal can activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement, i.e., the terminal can activate the GNSS measurement gap when the current time exceeds the validity period of GNSS positioning and deactivate the GNSS measurement gap when the current time does not exceed the validity period of GNSS positioning.

[0174] In some embodiments, the fifth information field and the sixth information field can be included in one piece of capability indication information, or the fifth information field and the sixth information field can be included in two pieces of capability indication information respectively, for example, the first piece of capability indication information includes the fifth information field, and the second piece of capability indication information includes the sixth information field.

[0175] In some embodiments, the configuration information includes a seventh information field, where the seventh information field is used to indicate a GNSS measurement gap, i.e., to indicate a measurement gap used for GNSS measurement.

[0176] In summary, the method provided in the embodiment enables the network device to send configuration information to the terminal according to the capability of the terminal to perform GNSS measurement based on the GNSS measurement gap.

[0177] The embodiment of the disclosure also provides a manner in which the network device sends GNSS measurement gap configuration information to the terminal, so that the terminal performs GNSS measurement based on the GNSS measurement gap.

[0178] Please refer to Figure 8 which shows a flowchart of a GNSS measurement method provided by an embodiment of the disclosure. The embodiment takes a network device in a communication system as shown in Figure 1 or Figure 2 for example. The method can include the following steps:

[0179] Step 801: Send configuration information to the terminal.

[0180] The configuration information is used to indicate a GNSS measurement gap, and the configuration information is sent by a network device, such as a base station, to the terminal. In some embodiments, the configuration information is pre-configured by the network device.

[0181] For example, the GNSS measurement gap is a time window in which the terminal performs GNSS measurement.

[0182] In some embodiments, the configuration information includes at least one of the following parameters:

[0183] • SFN and subframe of the measurement gap;

[0184] • repetition period of the measurement gap;

[0185] • offset parameter of the measurement gap;

[0186] • gap length of the measurement gap;

[0187] • time advance of the measurement gap;

[0188] • a gap type of the measurement gap;

[0189] • a gap identification of the measurement gap;

[0190] • a gap priority of the measurement gap;

[0191] • configuration indication information of the measurement gap.

[0192] Wherein, the repetition period of the measurement gap is used to indicate that the measurement gap repeats according to a specified period length, the offset parameter of the measurement gap is used to indicate that the measurement gap is offset from the SFM by a specified number of subframes, the gap length of the measurement gap is used to indicate the time length of the time window in which the measurement can be performed, the time advance of the measurement gap is used to compensate for the transmission delay of the configuration information, the gap type of the measurement gap includes at least one of per UE gap, per FR1 gap, and per FR2 gap, wherein FR1 (Frequency Range 1) and FR2 (Frequency Range 2) are two frequency ranges specified by 5G NR respectively, the gap ID is used to indicate different measurement gaps, the gap priority of the measurement gap is used to indicate the adoption order among multiple measurement gaps, and the configuration indication information of the measurement gap is used to indicate whether the measurement gap is a measurement gap corresponding to the configuration information pre-configured by the network device.

[0193] It should be understood that the above parameters can be pre-configured by the network device or agreed by the protocol, and the present disclosure does not limit this.

[0194] In some embodiments, the above-mentioned GNSS measurement gap can be a measurement gap dedicated to GNSS measurement, or a measurement gap in which GNSS measurement is multiplexed with other measurements, such as a measurement gap in a scenario in which a base station measurement service cell signal is multiplexed with GNSS measurement.

[0195] In summary, the technical solution provided by the present embodiment provides a solution for the configuration of the GNSS measurement gap. The network device sends configuration information to the terminal to indicate the GNSS measurement gap, so that the terminal performs GNSS measurement based on the GNSS measurement gap.

[0196] For example, the network device sends indication information to the terminal before or after sending the configuration information to the terminal.

[0197] First, the case where the network device instructs the terminal to activate the GNSS measurement gap is described.

[0198] Please refer to Figure 9 which shows a flowchart of a GNSS measurement method provided by an embodiment of the present disclosure. The present embodiment takes the method as being applied to Figure 1 orFigure 2 The network device in the illustrated communication system is used for illustration. The method can include the following steps:

[0199] At step 901, first indication information is sent to the terminal.

[0200] The first indication information is used to activate a GNSS measurement gap.

[0201] In some embodiments, the first indication information is used to indicate the activation of the GNSS measurement gap, or the first indication information is used to instruct the terminal to perform GNSS measurement, i.e., the first indication information can directly instruct the terminal to activate the GNSS measurement gap, or can instruct the terminal to perform GNSS measurement, so that the terminal activates the GNSS measurement gap.

[0202] Optionally, the first indication information can be RRC signaling, or MAC CE, or DCI.

[0203] In some embodiments, the first indication information includes at least one of the following information fields:

[0204] • A first information field is used to indicate the activation of the GNSS measurement gap, i.e., the network device directly instructs the terminal to activate the GNSS measurement gap, and the terminal receiving the first indication information can directly activate the GNSS measurement gap based on the first information field.

[0205] Optionally, the first information field is used to instruct the terminal to switch a pre-configured GNSS measurement gap to an activated state, so as to perform GNSS measurement based on the activated GNSS measurement gap; or the first information field is used to indicate a GNSS measurement gap that needs to be activated, so that the terminal performs GNSS measurement based on the GNSS measurement gap activated by the first information field.

[0206] • A second information field is used to instruct the terminal to perform GNSS measurement, i.e., the network device instructs the terminal to perform GNSS measurement, and the terminal receiving the first indication information can activate the GNSS measurement gap based on the requirement of GNSS measurement indicated by the second information field. Optionally, the second information field is used to instruct the terminal to start a GNSS measurement process.

[0207] In some embodiments, the first indication information can be sent by the network device to the terminal actively, or can be sent by the network device based on an activation request of the terminal.

[0208] In the case where the first indication information is sent by the network device based on the activation request of the terminal, the network device receives the activation request before sending the first indication information to the terminal. The activation request is used to request the activation of the GNSS measurement gap.

[0209] Exemplarily, the receiving the activation request is implemented by receiving uplink medium access control layer control signaling sent by the terminal, wherein the activation request is included in the uplink medium access control layer control signaling.

[0210] Secondly, the case that the terminal initiatively activates the GNSS measurement gap is described.

[0211] In some embodiments, the network device first indicates the activation permission of the GNSS measurement gap to the terminal, that is, after the network device indicates the activation permission of the GNSS measurement gap to the terminal, the terminal initiatively activates the GNSS measurement gap.

[0216] Optionally, the second indication information can be RRC signaling, or MAC CE, or DCI.

[0217] In some embodiments, the second indication information can include an information field used to indicate that the terminal has the permission to activate the GNSS measurement gap.

[0218] In some embodiments, the above step 1001 is executed in the case that the terminal initiatively activates the GNSS measurement gap, that is, the network device executes the above step 1001 before the terminal activates the GNSS measurement gap.

[0219] Next, the case that the network device indicates the terminal to deactivate the GNSS measurement gap is described.

[0220] Please refer to Figure 11 , which shows a flowchart of a GNSS measurement method provided by an embodiment of the present disclosure.

[0228] The fourth information field is used for indicating the terminal to stop GNSS measurement, that is, the network device indicates the terminal to stop GNSS measurement, and the terminal receiving the third indication information can deactivate the GNSS measurement gap based on the requirement of the fourth information field for stopping GNSS measurement. Optionally, the fourth information field is used for indicating the terminal to stop the GNSS measurement process.

[0229] In some embodiments, the third indication information can be sent by the network device to the terminal actively, or can be sent by the network device based on the deactivation request of the terminal, and the present disclosure does not limit this.

[0230] In the case that the third indication information is sent by the network device based on the deactivation request of the terminal, the network device receives the deactivation request before sending the third indication information to the terminal. The deactivation request is used for requesting deactivation of the GNSS measurement gap.

[0231] For example, receiving the deactivation request is implemented by receiving the uplink medium access control layer control signaling sent by the terminal, wherein the deactivation request is included in the uplink medium access control layer control signaling.

[0232] Finally, the case that the terminal initiatively deactivates the GNSS measurement gap is described.

[0233] In some embodiments, the network device first indicates the deactivation permission of the GNSS measurement gap to the terminal, that is, after the network device indicates the deactivation permission of the GNSS measurement gap to the terminal, the terminal initiatively deactivates the GNSS measurement gap.

[0247] For example, the network device receives the capability indication information sent by a terminal, the network device knows that the terminal can perform GNSS measurement, the capability indication information includes the sixth information field, and the network device knows that the terminal can activate and deactivate the GNSS measurement gap based on the GNSS measurement requirement, i.e., the terminal can activate the GNSS measurement gap when the current time exceeds the validity period of GNSS positioning and deactivate the GNSS measurement gap when the current time does not exceed the validity period of GNSS positioning.

[0248] In some embodiments, the capability indication information can include the fifth information field and the sixth information field simultaneously, or the capability indication information can include the fifth information field and the sixth information field respectively.
