[0136] As shown in Figure 1A, a communication system 100 includes a terminal 101 and a network device 102. The network device 102 may be an access network device.

[0139] In some embodiments, the technical solution of the present disclosure can be applied to the open radio access network (Open RAN) architecture. In this case, the interfaces between access network devices or within access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0140] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0141] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0142] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or some of the entities in the communication system 100 , but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system 100 may include all or some of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A .

In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A with 5G).

[0145] In the disclosed embodiments, the continuous emergence of new internet applications such as augmented reality (AR), virtual reality (VR), and vehicle-to-vehicle (V2V) communication has placed higher demands on wireless communication technology, driving the continuous evolution of wireless communication technology to meet these application needs. Currently, cellular mobile communication technology is in the process of evolving into a new generation of technology. A key feature of this new generation of technology is the flexible configuration that supports multiple service types. Different service types have different requirements for wireless communication technology. For example, enhanced mobile broadband (eMBB) service types primarily require high bandwidth and high speed; ultra-reliable low-latency communications (URLLC) service types primarily require high reliability and low latency; and massive machine type communications (mMTC) service types primarily require a large number of connections. Therefore, the next generation of wireless communication systems requires flexible and configurable designs to support the transmission of multiple service types.

[0146] Satellite communications are considered a key aspect of future wireless communication technology. Satellite communications refer to communications conducted by ground-based radio communication equipment using satellites as relays. Satellite communication systems consist of satellite and ground components. Satellite communications are characterized by a wide range, enabling communication between any two points within the range of the satellite's radio waves, and high reliability, as well as being less susceptible to land-based disasters.

[0147] Satellite communications, as a supplement to terrestrial communication systems, offer the following advantages: 1. Extended coverage: Satellite communications can be used to address areas where cellular communication systems are inaccessible or costly, such as oceans, deserts, and remote mountainous areas. 2. Emergency communications: In extreme situations such as disasters (e.g., earthquakes) where cellular communication infrastructure is unavailable, satellite communications can quickly establish a connection. 3. Industry applications: For example, satellite communications can be used to reduce latency in long-distance, delay-sensitive services.

[0148] It is foreseeable that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the intelligent connection of all things.

[0149] In the embodiment of the present disclosure, in the scenario of satellite communication, due to the long signal transmission distance between the transmitter and the receiver, data transmission takes a long time. For transmission with uplink and downlink relationship, an offset parameter (K offset ) to compensate for the transmission delay. Among them, K offset It can be applied in various operations, such as physical uplink shared channel (PUSCH) transmission scheduled by downlink control information (DCI), transmission of hybrid automatic repeat request (HARQ) feedback information, and transmission of media access control (MAC) control element (CE).

[0150] In some embodiments, propagation delay in satellite communication systems is significantly longer than that in terrestrial mobile systems, ranging from a few milliseconds to hundreds of milliseconds depending on the altitude of the satellite or airborne platform and the type of payload in the satellite communication system. Therefore, in satellite communication systems, terminals need to apply a larger timing advance (TA) value, which can result in large offsets in their downlink (DL) and uplink (UL) frame timing. Figure 1B illustrates a scenario in which a terminal applies a larger TA and the DL and UL frames of a network device (e.g., an access network device) are aligned. Figure 1C illustrates another scenario in which alignment between the DL and UL frames of the access network device is not required. The terminal applies a terminal-specific TA (e.g., a UE-specific TA) to align the DL and UL frame timing at a predetermined reference point. However, for the scenario shown in Figure 1C, additional complexity is required on the network device side to manage the corresponding scheduling timing for this scenario. Therefore, various timing relationships need to be enhanced to cope with large offsets in the timing of the terminal's DL and UL frames.

[0151] Then, in the scenario of satellite communication, the terminal needs to know its own location information in order to perform uplink synchronization compensation. In some embodiments, the terminal can obtain its own location information through a navigation satellite system, such as a global navigation satellite system (GNSS).

[0152] In some embodiments, the global navigation satellite system (GNSS) may include China's Beidou Navigation Satellite System (BDS), the United States' Global Positioning System (GPS), Russia's GLONASS, and the European Union's Galileo Navigation Satellite System (GALILEO), among other navigation satellite systems and their evolutionary systems. Of course, other navigation systems may also be included, and the present disclosure does not specifically limit this.

[0153] In some embodiments, for IoT terminals, the cellular module and the GNSS module do not support simultaneous operation, but sporadic transmission can be supported. After obtaining the GNSS measurement results, the terminal can send GNSS available time information (used to indicate the GNSS validity duration) to the network device. When the GNSS validity period of the terminal expires, the terminal will enter the idle state.

[0154] (IDLE) status.

[0155] In some embodiments, after the terminal enters the IDLE state, the need to re-acquire the GNSS validity period will cause unnecessary delays. Therefore, the network device can trigger the terminal to perform GNSS measurements in the connected state to prevent the terminal from entering the IDLE state.

[0156] In some embodiments, before the terminal performs GNSS measurement, the terminal also needs to send time information required for the measurement (such as GNSS positioning duration information (used to indicate the GNSS position fix time duration)) to the network device, so that the network device can configure an appropriate measurement gap for the terminal. In one embodiment, the measurement gap can also be described as a GNSS measurement gap.

[0157] In some embodiments, if a terminal successfully performs a GNSS measurement, it can indicate the remaining GNSS validity duration to the network device. Specifically, the terminal can use message 3 (msg3) during the random access process. However, the network device is not aware of the terminal's motivation for initiating the random access process, nor does it need to indicate the remaining GNSS validity duration to the network device. Therefore, unnecessary redundancy in msg3 information may result, affecting uplink coverage.

[0158] It should be noted that the terms "GNSS remaining validity period" and "GNSS validity period" are interchangeable. The terms "GNSS measurement" and "GNSS positioning" are interchangeable. The terms "GNSS measurement execution successful," "GNSS measurement successfully executed," "GNSS measurement successfully executed," "GNSS measurement successfully executed," "GNSS measurement successful," and "measurement success" are interchangeable.

[0159] FIG2A is a first flow chart of a communication method according to an embodiment of the present disclosure. The present disclosure embodiment relates to a communication method, which is used in a communication system 100. As shown in FIG2A, the communication method according to the embodiment of the present disclosure includes steps S2110 to S2150.

[0160] In step S2110 , the terminal determines that the measurement gap length information sent by the network device is not received.

[0161] In some embodiments, the measurement gap length information is used to indicate the length of the measurement gap configured by the network device for the terminal.

[0162] In one embodiment, the term "length of the measurement gap" can be interchanged with "time length of the measurement gap", "duration of the measurement gap", "duration of the measurement gap", "duration of the measurement gap", etc.

[0163] In some embodiments, the measurement gap may be periodic or non-periodic.

[0164] In some embodiments, when the network device does not configure the length of the measurement gap for the terminal, the network device does not send the measurement gap length information to the terminal, and thus the terminal cannot receive the measurement gap length information.

[0165] In step S2120, the terminal determines the time length indicated by the time information sent by itself (ie, the first time information) as the length of the measurement gap.

[0166] In some embodiments, the first time information is time information sent by the terminal to the network device.

[0167] In some embodiments, the first time information is time information associated with GNSS measurement, GNSS-related time information, or GNSS measurement assistance information, and is used to indicate the length of time associated with the GNSS measurement. Exemplarily, the first time information (i.e., the time information sent by the terminal) may include at least one of GNSS positioning duration information and GNSS available time information. GNSS positioning duration information is used to indicate the time required for GNSS positioning, and GNSS available time information is used to indicate the GNSS validity period. It should be noted that the above-mentioned first time information may be sent by the terminal to the network device after the last GNSS measurement is completed.

[0168] In some embodiments, the length of the measurement gap is equal to the time length indicated by the first time information sent by the terminal.

[0169] In some embodiments, since the terminal and the network device need to have a consistent understanding of the measurement gap, the network device determines that the measurement gap length information is not received, and determines the time length indicated by the first time information as the length of the measurement gap.

[0170] In one embodiment, the term "time length" can be interchanged with "length", "duration", "duration", "duration duration", etc.

[0171] In step S2130 , the terminal performs GNSS measurement in the measurement gap.

[0172] In some embodiments, the GNSS measurement may be triggered by a network device. Exemplarily, the network device sends a trigger instruction to the terminal to instruct the terminal to perform the GNSS measurement. The terminal performs the GNSS measurement in response to the trigger instruction.

[0173] In some embodiments, the network device triggers the terminal to perform GNSS measurement non-periodically, and the terminal can obtain GNSS positioning during the re-measurement interval.

[0174] In some embodiments, the trigger instruction can be at least one of high-layer signaling, such as radio resource control (RRC) signaling, broadcast messages, system messages, media access control (MAC) control elements (CE), downlink control information (DCI), and signaling carried by the physical downlink shared channel (PDSCH). Of course, the trigger instruction can also be carried in other signaling and sent, which is not specifically limited in the embodiments of the present disclosure. Exemplarily, the trigger instruction is a MAC CE.

[0175] In some embodiments, the trigger instruction is a MAC CE. In this case, the start position of the measurement gap can be n+X, where n is the end position of the MAC CE reception subframe / time slot and X is predefined or preconfigured. Alternatively, the start position of the measurement gap can be based on the current GNSS validity period, with or without a certain delay.

[0176] In some embodiments, the terminal may also autonomously perform GNSS measurements. For example, the terminal receives an indication from a higher layer and determines that it can autonomously perform GNSS measurements. The terminal autonomously performs GNSS measurements if certain conditions are met, such as if it has not received a trigger instruction from the network to trigger GNSS measurements and the terminal's GNSS is about to expire.

[0177] In some embodiments, the terminal may determine whether to autonomously perform GNSS measurements based on network configuration. In one embodiment, the network device may configure the terminal to enable the autonomous measurement function. If enabled, the terminal may autonomously perform GNSS measurements. If disabled, the terminal may be triggered by the network device to perform GNSS measurements.

[0178] In some embodiments, the terminal does not need to transmit or receive any channel / signal within the measurement gap before successfully performing GNSS measurements.

[0179] In step S2140 , the network device sends second information after the measurement gap ends.

[0180] In some embodiments, the terminal receives the second information after the measurement gap ends.

[0181] In some embodiments, the second information is used to instruct the terminal to send the GNSS validity period of the terminal to the network device.

[0182] In one embodiment, the first uplink resource is a resource used by a network device to schedule a terminal to perform uplink transmission, such as a resource scheduled by an uplink grant (UL grant).

[0183] In some embodiments, the name of the second information is not limited, and it can be, for example, "indication information", "trigger indication information", "uplink indication information", "target indication information", etc.

[0184] In some embodiments, the network device sends the first message after the measurement gap ends. In one embodiment, the first message is used to schedule the first uplink resource. In one embodiment, the first message is used to indicate the first uplink resource.

[0185] In some embodiments, the first message is used to instruct the terminal to send the first information on a designated resource, where the designated resource is the first uplink resource.

[0186] In some embodiments, the name of the first message is not limited, and it can be, for example, "scheduling message", "uplink transmission scheduling message", etc.

[0187] In some embodiments, step S2104 may be omitted. At this time, the terminal autonomously sends the first information.

[0188] In some embodiments, when the terminal autonomously sends the first information, the terminal may autonomously determine the first uplink resource to send the first information.

[0189] In step S2150, the terminal sends first information on a first uplink resource.

[0190] In some embodiments, a network device receives first information.

[0191] In some embodiments, the terminal sends the first information on the uplink resource indicated by the second information.

[0192] In some embodiments, after successfully performing GNSS measurement and receiving the second information, the terminal sends the first information on the first uplink resource.

[0193] In some embodiments, the network device receives first information on a first uplink resource.

[0194] In some embodiments, the first information is used to indicate that the terminal successfully performs GNSS measurement within the measurement gap.

[0195] In some embodiments, the first information is used to indicate that the GNSS measurement performed by the terminal in the measurement gap is successful.

[0196] In some embodiments, the name of the first information is not limited, and it can be, for example, "indication information", "measurement indication information", "measurement success indication information", etc.

[0197] For example, FIG3A is a schematic diagram of a first example of a sending location for first information provided according to an embodiment of the present disclosure. As shown in FIG3A , after the measurement gap ends, the terminal detects a first message sent by a network device. The first message may carry second information. The indication information is used to instruct the terminal to send the first information on a first uplink resource, so that after receiving the first information sent by the terminal, the network device can determine that the terminal has successfully performed a GNSS measurement.

[0198] In some embodiments, the first information may be used to indicate the GNSS validity period of the terminal. For example, the first information may be GNSS available time information. In this case, after receiving the first information, the network device may also obtain the GNSS validity period of the terminal.

[0199] In some embodiments, after performing a GNSS measurement, the terminal sends the GNSS validity period to the network device. In one embodiment, the terminal may send the GNSS validity period once per measurement. In one embodiment, the terminal may also send a new GNSS validity period to the network device when the length of the GNSS validity period changes.

[0200] In some embodiments, the terminal may also send other information, such as GNSS positioning duration information, at the same time as sending the GNSS available time information, to indicate to the network device the time required for GNSS positioning. For example, the GNSS available time information and the GNSS positioning duration information may be sent in the same message or in different messages.

[0201] In some embodiments, the terminal may send GNSS available time information and GNSS positioning continuity information respectively. At this time, the GNSS positioning continuity information may be carried in, for example, an RRC connection reestablishment complete message (RRCConnectionReestablishmentComplete or

[0202] RRCConnectionReestablishmentComplete-NB), RRC connection reconfiguration completion message in the handover scenario

[0203] (RCConnectionReconfigurationComplete for HO case).

[0204] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2110 to S2150. For example, step S2150 can be implemented as an independent embodiment. For example, step S2130 and step S2150 can be implemented as independent embodiments. For example, steps S2130 to S2150 can be implemented as independent embodiments. For example, steps S2110 to S2130 and step S2150 can be implemented as independent embodiments. For example, the combination of steps S2110 to S2150 can be implemented as an independent embodiment. It should be noted that one or more steps in steps S2110 to S2150 may form a possible independent embodiment, but are not limited to this.

[0205] In some embodiments, step S2110, step S2120, step S2130, and step S2140 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0206] In some embodiments, step S2110, step S2120, and step S2140 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0208] In some embodiments, step S2140 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0209] In the above embodiment, the terminal indicates that it has successfully performed the GNSS measurement by sending the first information to the network device. In this way, the terminal and the network device can reach an agreement on the result of the GNSS measurement performed by the terminal, avoiding information asymmetry between the terminal and the network device.

[0226] Exemplarily, the first information may be carried in message 1 (msg1) during a random access process. In one embodiment, the random access process may be 4-step random access (4-step RACH) or 2-step random access (2-step RACH), which is not specifically limited in the embodiments of the present disclosure.

[0227] In some embodiments, the terminal sends the first information via PRACH signaling.

In one embodiment, the GNSS positioning duration information and the first information may be sent in the same message (e.g., msg1).

[0229] In some embodiments, the terminal sends a third message to the network device on the first random access resource after the measurement gap ends. The third message carries the first information. Exemplarily, the first random access resource can be a random access opportunity (RO) resource after the measurement gap ends, such as the first RO resource after the measurement gap ends, or any RO resource after the measurement gap ends. In some embodiments, the term "RO resource" is interchangeable with "available RO resources," "resources corresponding to the RO," "resources where the RO is located," and "RO location."

[0230] In some embodiments, the first random access resource may include the first random access resource (e.g., the first RO resource) after the measurement gap ends. Alternatively, the first random access resource may include a random access resource within a preset time window after the measurement gap ends. Exemplarily, at least one random access resource may exist within the preset time window after the measurement gap ends. The terminal may select any first random access resource from the resource, including one for sending a random access sequence (i.e., the first information). In one embodiment, the preset time window may be predefined or preconfigured, or may be configured by the network device for the terminal.

[0231] In some embodiments, FIG3B is a schematic diagram of a second example of a sending location for first information provided according to an embodiment of the present disclosure. As shown in FIG3B , the terminal sends the first information on an RO resource after the measurement gap ends.

[0232] In step S2250, the network device sends third information.

[0233] In some embodiments, the terminal receives third information.

[0234] In some embodiments, the third information is used to instruct the terminal to send the GNSS validity period on the second uplink resource. In one embodiment, the second uplink resource is configured for the terminal by the network device in response to the first information.

[0235] In some embodiments, the name of the third information is not limited, and it can be, for example, "response information", "random access response information", "trigger reporting information", etc.

[0273] FIG2D is a fourth flow chart of a communication method according to an embodiment of the present disclosure. This embodiment of the present disclosure relates to a communication method, which is used in the communication system 100. As shown in FIG2D , the communication method according to the embodiment of the present disclosure includes steps S2410 to S2440.

[0274] In step S2410 , the network device sends measurement gap length information.

[0275] In some embodiments, the terminal receives length information of the measurement gap.

[0276] In some embodiments, the measurement gap length information is used to indicate the length of the measurement gap. In one embodiment, the measurement gap length information may also be used to indicate the duration of the measurement gap.

[0277] In some embodiments, the measurement gap length information is configured by a network device for the terminal. In one embodiment, the network device sends radio resource control (RRC) signaling or a medium access control (MAC) control element (CE), wherein the RRC signaling or MAC CE carries the measurement gap length information.

[0278] In some embodiments, the length of the measurement gap is greater than or equal to the time length indicated by the time information sent by the terminal to the network device.

[0279] In one embodiment, the time information sent by the terminal may include at least one of GNSS positioning duration information and GNSS available time information. The GNSS positioning duration information is used to indicate the time required for GNSS positioning, and the GNSS available time information is used to indicate the GNSS validity period. It should be noted that the time information sent by the terminal is the most recently reported time by the terminal, or is sent by the terminal after the last GNSS measurement. Exemplarily, the length of the measurement gap is greater than or equal to the most recently reported time required for GNSS positioning by the terminal.

[0280] In some embodiments, the network device sends measurement gap configuration information. The measurement gap configuration information may include at least one of measurement gap start position information, measurement gap length information, etc. The measurement gap start position information is used to indicate the start position of the measurement gap.

[0281] In some embodiments, the length information of the measurement gap may be determined by the network device based on time information sent by the terminal to the network device.

[0282] In some embodiments, the starting position of the measurement gap may be configured by the network device for the terminal. In some embodiments, the starting position of the measurement gap may also be predefined or preconfigured. Exemplarily, the starting position of the measurement gap may be the end of the GNSS validity period, the time domain position N time units after receiving a GNSS measurement trigger instruction, or the time domain position N time units after the location where the terminal feedbacks HARQ information, where N is a positive integer.

[0283] In some embodiments, the above-mentioned "time unit" can be understood as "frame", "subframe", "time slot", "sub-time slot", "symbol", etc.

[0284] In some embodiments, the terminal determines the time length indicated by the measurement gap length information configured by the network device as the length of the measurement gap.

[0285] In step S2420 , the terminal performs GNSS measurement within the length of the measurement gap.

[0286] In some embodiments, the GNSS measurement may be triggered by a network device. Exemplarily, the network device sends a trigger instruction to the terminal to instruct the terminal to perform the GNSS measurement. The terminal performs the GNSS measurement in response to the trigger instruction.

[0287] In some embodiments, the terminal may also autonomously perform GNSS measurements. For example, the terminal receives an indication from a higher layer and determines that it can autonomously perform GNSS measurements. The terminal autonomously performs GNSS measurements if certain conditions are met, such as if it has not received a trigger instruction from the network to trigger GNSS measurements and the terminal's GNSS is about to expire.

[0288] In some embodiments, the trigger instruction can be at least one of high-layer signaling, such as radio resource control (RRC) signaling, broadcast messages, system messages, media access control (MAC) control elements (CE), downlink control information (DCI), and signaling carried by a physical downlink shared channel (PDSCH). Of course, the first information can also be carried in other signaling and sent, which is not specifically limited in the embodiments of the present disclosure. Exemplarily, the trigger instruction is a MAC CE.

[0289] In step S2430, the terminal determines that a difference between the length of the measurement gap and the time length indicated by the time information sent by the terminal is less than or equal to a first threshold.

[0290] In some embodiments, the terminal determines that the length of the measurement gap is greater than the time length indicated by the time information sent by the terminal.

[0291] In some embodiments, the time information sent by the terminal may include GNSS positioning duration information. The time length indicated by the time information may be the length of time required for GNSS positioning.

[0292] In some embodiments, the terminal may determine that the difference between the length of the measurement gap configured by the network device and the length of the time required for GNSS positioning is less than or equal to a preset value X (i.e., a first threshold), where the value of X is greater than 0. In one embodiment, the first threshold may be predefined or preconfigured, or may be configured by the network device for the terminal.

[0293] In step S2440, the terminal sends first information after the measurement gap ends.

[0294] The optional implementation of step S2440 can refer to the optional implementation of step S2130 in Figure 2A, step S2240 in Figure 2B, and other related parts in the embodiments involved in Figures 2A and 2B, which will not be repeated here.

[0295] In some embodiments, the terminal determines that the difference between the length of the measurement gap and the time length indicated by the time information sent by the terminal is greater than a first threshold. In this case, the terminal initiates a random access process within the measurement gap and sends second time information, such as GNSS available time information, on uplink resources scheduled by the network device (such as resources corresponding to msg3). In some embodiments, the terminal may also send the second time information via a MAC CE within the measurement gap.

[0296] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2410 to S2440. For example, steps S2430 and S2440 can be implemented as independent embodiments. For example, steps S2420 and S2440 can be implemented as independent embodiments.

[0421] In some embodiments, the above method may include the method described in the above embodiments on the communication system side and the network device side, which will not be repeated here.

[0422] In some embodiments, the present disclosure relates to a communication method, comprising:

[0423] In the first step, the terminal determines whether configuration indication information regarding the length of the measurement gap (ie, measurement gap length information) has been received. The configuration information may be sent to the terminal via RRC signaling or MAC CE.

[0424] In the second step, if the terminal does not receive the configuration information of the measurement gap length, the terminal determines that the length of the measurement gap is the length of the GNSS position fix time duration reported by the terminal.

[0425] In the third step, the terminal executes one of the following:

[0426] In the first case (option 1), the terminal receives a scheduling instruction from a network device (such as a base station) after the measurement gap ends, and reports the GNSS available time information according to the instruction.

[0427] In some embodiments, after a successful GNSS measurement, the terminal detects a scheduling instruction sent by a network device, which may carry target indication information (i.e., second information). This indication information is used to instruct the terminal to report GNSS available time information on the indicated resource (the first uplink resource). When the network device receives the GNSS available time information sent by the terminal, it can determine that the terminal has successfully performed the GNSS measurement and obtained the GNSS available time information.

[0428] In the second case (option 2), the terminal initiates a random access process on an available RO resource (ie, the first random access resource) after the measurement gap ends, and reports GNSS available time information in msg3 (ie, the second message).

[0429] In some embodiments, the terminal sends a random access sequence (preamble) on the first available RO resource after the measurement gap ends to request uplink resources. The terminal can send GNSS available time information on msg3 based on the instruction of the network device.

[0430] In some embodiments, the terminal sends a random access sequence on one of the RO resources to request uplink resources at multiple RO locations (i.e., the first random access resource) within a predefined time (i.e., a preset time window) after the end of the measurement gap. The terminal may report GNSS available time information in msg3 (i.e., the second message) based on the instruction of the network device.

[0431] In option 3, the terminal sends GNSS availability time information within a predefined time window after the measurement gap ends. The network device determines whether the terminal has successfully performed a GNSS measurement based on whether it receives the terminal's uplink transmission (i.e., GNSS availability time information) within the predefined time window.

[0432] In some embodiments, after the first step, the terminal may further execute: if the terminal receives configuration indication information of the length of the measurement gap, the terminal determines whether the length of the measurement gap is greater than or equal to a predefined threshold than the time information reported by the terminal, such as the length of the time required for GNSS positioning.

[0433] In the first case, if the length of the measurement gap is less than or equal to a predefined threshold than the time length indicated by the time information reported by the terminal, the terminal may receive a scheduling instruction from the network device after the measurement gap ends and report the GNSS available time information based on the scheduling instruction. Alternatively, the terminal may initiate a random access procedure on the first available RO resource after the measurement gap ends and report the GNSS available time information in msg3.

[0434] In the second case, if the length of the measurement gap is greater than the time length indicated by the time information reported by the terminal by a predefined threshold, the terminal can initiate a random access process within the measurement gap if it successfully performs GNSS measurement within the measurement gap, and report the GNSS available time information in the msg.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
