First, some technical knowledge involved in this disclosure is introduced:

NTN Technology

At present, relevant standard organizations are studying NTN technology, which generally uses satellite communication to provide communication services to ground users. Compared with ground-based cellular communication networks, satellite communication has many unique advantages. First, satellite Communications are not limited by the user's geographical location. For example, general terrestrial communications cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be set up or where there is no communication coverage due to sparse population. For satellite communications, since one satellite can cover a large area of land, and satellites can orbit the earth, in theory every corner of the earth can be covered by satellite communications. Secondly, satellite communications have great social value. Satellite communications can be covered at a low cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communications and mobile Internet technologies, which is conducive to narrowing the digital divide with developed areas and promoting the development of these areas. Thirdly, satellite communications have long distances, and the cost of communications does not increase significantly as the communication distance increases; finally, satellite communications are highly stable and are not restricted by natural disasters.

According to the different orbital altitudes, communication satellites are divided into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit) satellites, HEO (High Elliptical Orbit) satellites, etc. At present, the main research is on LEO and GEO.

1. LEO

The altitude of low-orbit satellites ranges from 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 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 transmission power requirement for user terminal equipment is not high.

2. GEO

The geosynchronous orbit satellite has an orbit altitude of 35786km and a rotation period around the earth of 24 hours. The signal propagation delay of single-hop communication between users is generally 250ms.

In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. 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 tens to hundreds of kilometers.

Table 1 shows the satellite altitude, orbit, and satellite coverage of a typical NTN network:

Table 1

IoT terminal devices include: at least one of: BL UE (Bandwidth reduction and Low complexity UE), UE in CE mode (UE in Coverage Enhancement mode), and NB-IOT UE (Narrow Band Internet of Things UE).

The embodiments of the present disclosure may be applied to an NTN system, as shown in FIG. 1 and FIG. 2 .

Please refer to FIG1, which shows a schematic diagram of an NTN system, in which the communication satellite in the NTN system is a transparent payload satellite, wherein transparent payload refers to a transmission method that directly forwards without modulation, demodulation or other intermediate processing. As shown in FIG1, 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.

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 FIG1 , the access network device 40 can be deployed on the ground, and the uplink and downlink communications between the terminal device 10 and the access network device 40 can be transferred and transmitted 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 an uplink signal to the satellite 20, the satellite 20 forwards the uplink signal to the NTN gateway 30, and the NTN gateway 30 forwards the uplink signal to the access network device 40, and the access network device 40 subsequently sends the uplink signal to the core network device 50. Taking downlink transmission as an example, a downlink signal from the core network device 50 is sent to the access network device 40, the access network device 40 sends a downlink signal to the NTN gateway 30, the NTN gateway 30 forwards the downlink signal to the satellite 20, and the satellite 20 forwards the downlink signal to the terminal device 10.

In the NTN system, the satellite 20 has the functions of frequency conversion and signal amplification. The satellite 20 does not The satellite 20 demodulates the signal and is similar to a repeater.

Please refer to FIG2 , which shows a schematic diagram of another NTN system, in which the communication satellite in the NTN system is a regenerative payload satellite. As shown in FIG2 , the NTN system includes: a terminal device 10, a satellite 20, an NTN gateway 30 and a core network device 50.

In the architecture shown in FIG2 , the function of the access network device 40 is integrated in the satellite 20, that is, the satellite 20 has the function of the access network device 40. The terminal device 10 and the satellite 20 can communicate through the air interface (such as the Uu interface). The satellite 20 and the NTN gateway 30 (usually located on the ground) can communicate through the SRI (Satellite Radio Interface). In the NTN system, the satellite receives the signal, demodulates and decodes it, then re-encodes and modulates it, and sends the regenerated signal through the satellite frequency band.

In the architecture shown in FIG2 , taking uplink transmission as an example, the terminal device 10 sends an uplink signal to the satellite 20, the satellite 20 forwards the uplink signal to the NTN gateway 30, and the NTN gateway 30 sends the uplink signal to the core network device 50. Taking downlink transmission as an example, a downlink signal from the core network device 50 is sent to the NTN gateway 30, the NTN gateway 30 forwards the downlink signal to the satellite 20, and the satellite 20 forwards the downlink signal to the terminal device 10.

In the network architecture shown in Figures 1 and 2 above, the access network device 40 is a device for providing wireless communication services to the terminal device 10. A connection can be established between the access network device 40 and the terminal device 10, so that communication can be carried out through the connection, including the interaction of signaling and data. There can be multiple access network devices 40, and two adjacent access network devices 40 can also communicate with each other in a wired or wireless manner. The terminal device 10 can switch between different access network devices 40, that is, establish connections with different access network devices 40.

Taking a cellular communication network as an example, the access network device 40 in the cellular communication network may be a base station. A base station is a device deployed in an access network to provide wireless communication functions for a terminal device 10. Base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems that use different wireless access technologies, the names of devices with base station functions may be different. For example, in a 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name "base station" may change. For the convenience of description, in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as base stations or access network devices.

In addition, the terminal device 10 involved in the embodiments of the present disclosure may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of UE (User Equipment), MS (Mobile Station), terminal devices, etc. For the convenience 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 in some places to represent "terminal device". In the embodiments of the present disclosure, "network device" may be an access network device (such as a base station) or a satellite.

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

In addition, in the embodiments of the present disclosure, the terms "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 applied to LTE systems, 5G systems, and subsequent evolution systems of 5G NR systems or other communication systems, and the present disclosure does not limit this.

For some IOT terminals, it is impossible to support simultaneous GNSS reception and LTE transmission and reception. The validity of the GNSS positioning obtained by the terminal can only be maintained for a period of time. After this period of time, the GNSS positioning corresponding to the terminal becomes invalid, and the terminal needs to re-acquire the GNSS positioning. For this reason, the embodiments of the present disclosure provide a method for a terminal device to receive GNSS measurement gap configuration information, thereby performing GNSS measurement based on the GNSS measurement gap.

Please refer to FIG3, which shows a flow chart of a GNSS measurement method provided by an embodiment of the present disclosure. This embodiment is illustrated by applying the method to a terminal device in a communication system shown in FIG1 or FIG2. The method may include the following steps:

Step 301: Receive configuration information.

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

In some embodiments, the GNSS measurement gap is a time window in which the terminal performs GNSS measurement, that is, the terminal performs GNSS measurement based on the GNSS measurement gap.

Exemplarily, before step 301, the terminal device can obtain GNSS positioning. The GNSS positioning has a validity period. When the validity period of the GNSS positioning expires, it is determined that the GNSS positioning has timed out (GNSS position fix outdated).

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

In scenarios where the terminal needs to perform GNSS measurement, such as to obtain the latest GNSS positioning before the GNSS positioning fails, or to re-acquire the GNSS positioning after the GNSS positioning fails, the terminal can determine the GNSS measurement gap based on the configuration information and perform GNSS measurement within the time window corresponding to the GNSS measurement gap.

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

·Measure the SFN (System Frame Number) and subframe of the gap;

The repetition period of the measurement gap;

·Measurement gap offset parameters;

·Measure the gap length of the gap;

· Timing advance of the measurement gap;

The gap type of the measuring gap;

The gap ID of the measurement gap;

Gap priority for measuring gaps;

·Instructions on the configuration of measurement gaps.

Among them, the repetition period of the measurement gap is used to indicate that the measurement gap is repeated according to the specified period duration, 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 duration 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, and the gap type of the measurement gap includes at least one of the terminal measurement gap (per UE gap), the specified frequency range 1 measurement gap (per FR1 gap), and the specified frequency range 2 measurement gap (per FR2 gap), wherein FR1 (Frequency range 1) and FR2 (Frequency range 2) are two frequency ranges specified by 5G NR, respectively. p ID is used to indicate different measurement gaps, and the gap priority of the measurement gap is used to indicate the order of adoption between multiple measurement gaps. In some embodiments, multiple measurement gaps include a dedicated GNSS measurement gap configured for GNSS measurement and a measurement gap multiplexed with GNSS measurement and other measurements. Optionally, the measurement gap dedicated to GNSS measurement is preferentially used for GNSS measurement. When the measurement gap dedicated to GNSS measurement cannot be used, the measurement gap multiplexed with other measurements is used for GNSS measurement. In other embodiments, multiple measurement gaps include GNSS measurement gaps and other measurement gaps, such as reference signal measurement gaps. Optionally, the priority of the GNSS measurement gap is higher than the measurement gap of the reference signal, and the GNSS measurement is preferentially performed through the GNSS measurement gap. 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.

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

In some embodiments, the GNSS measurement gap may 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 measures a serving cell signal as a GNSS measurement gap.

After receiving the configuration information, the terminal may perform GNSS measurement based on the GNSS measurement gap indicated by the configuration information, that is, perform GNSS measurement within the time window corresponding to the GNSS measurement gap, where the GNSS measurement gap includes the following two states:

Activation status;

Deactivation state.

The activated state is used to indicate that the terminal uses the activated GNSS measurement gap to perform GNSS measurement; the deactivated state is used to indicate that the terminal stops GNSS measurement when the terminal uses the activated GNSS measurement gap to perform GNSS measurement.

In some embodiments, in response to the GNSS measurement gap being activated, the terminal uses the GNSS measurement gap to perform GNSS measurement; in response to the GNSS measurement gap being deactivated, the terminal stops the GNSS measurement.

In summary, the technical solution provided in this embodiment provides a solution for the configuration of the GNSS measurement gap. The terminal receives 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.

Exemplarily, in response to the GNSS measurement gap being activated, the GNSS measurement is performed using the GNSS measurement gap.

In some embodiments, before using the GNSS measurement gap to perform GNSS measurement, the terminal needs to activate the GNSS measurement gap. Optionally, the case where the terminal activates the GNSS measurement gap includes at least one of the following cases:

First, the terminal activates the GNSS measurement gap based on the instruction of the network device;

The second method is that the terminal actively activates the GNSS measurement gap.

First, a case where a terminal activates a GNSS measurement gap based on an instruction of a network device is described.

Please refer to FIG. 4, which is a flow chart of a GNSS measurement method provided by an embodiment of the present disclosure. This embodiment is illustrated by applying the method to a terminal device in the communication system shown in FIG. 1 or FIG. 2. The method may include the following steps:

Step 401: Receive first indication information.

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

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

Optionally, the first indication information may be RRC (Radio Resource Control protocol) signaling, or MAC CE (Media Access Control Control Element, uplink media access control layer control signaling), or DCI (Downlink Control Information, downlink control information).

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

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

Optionally, the first information field is used to instruct the terminal to switch a pre-configured GNSS measurement gap to an activated state, thereby performing 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 activated GNSS measurement gap indicated by the first information field.

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 GNSS measurement requirement indicated by the second information field. Optionally, the second information field is used to instruct the terminal to start the GNSS measurement process.

In some embodiments, the first indication information may be actively sent by the network device to the terminal, or may be sent by the network device based on an activation request from the terminal.

In the case where the first indication information is sent by the network device based on an activation request of the terminal, the terminal sends an activation request to the network device before receiving the first indication information, wherein the activation request is used to request activation of the GNSS measurement gap.

Exemplarily, the terminal sends an activation request to the network device by sending a UL MAC CE (UpLink Media Access Control Control Element, uplink media access control layer control signaling) to the network device, wherein the uplink media access control layer control signaling includes the activation request.

Secondly, the case where the terminal actively activates the GNSS measurement gap is described.

Please refer to FIG5, which is a flow chart of a GNSS measurement method provided by an embodiment of the present disclosure. This embodiment is illustrated by applying the method to a terminal device in the communication system shown in FIG1 or FIG2. The method may include the following steps:

Step 501: When the terminal meets the GNSS measurement conditions, activate the GNSS measurement gap.

The GNSS measurement conditions include at least one of the following:

The current time exceeds the validity period of GNSS positioning;

The remaining duration of the current GNSS positioning validity period is less than the threshold duration;

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

The current time exceeds the validity period of the GNSS positioning, that is, the GNSS positioning is invalid; that is, the expiration time of the validity period of the most recent GNSS positioning in the historical time is before the current time.

In some embodiments, the threshold duration is determined based on a duration corresponding to a GNSS measurement gap required to perform GNSS measurement before the GNSS positioning expires.

In some embodiments, the threshold number is determined based on a number of GNSS measurement gaps required to perform a GNSS measurement before the GNSS position fix expires.

The remaining time of the current GNSS positioning validity period is less than the threshold time. For example, if the threshold time is 1ms, then the current GNSS When the remaining time of the positioning validity period is less than 1ms, the GNSS measurement conditions are met.

Optionally, the threshold time length is preconfigured, or the threshold time length is predefined, that is, the threshold time length may be configured by the network device, or may be agreed upon by a protocol.

The number of GNSS measurement gaps before the current GNSS positioning expires is less than the threshold number. For example, 3 GNSS measurement gaps are required to perform GNSS measurement before the GNSS positioning expires, and the number of GNSS measurement gaps before the current GNSS positioning expires is 0.

Optionally, the threshold quantity is preconfigured, or the threshold quantity is predefined, that is, the threshold quantity may be configured by the network device, or may be agreed upon by a protocol.

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 authority to activate the GNSS measurement gap, and the second indication information is sent by the network device.

Exemplarily, when the terminal meets the GNSS measurement conditions, before activating the GNSS measurement gap, the network device grants the terminal permission to activate the GNSS measurement gap, and the terminal receives second indication information, and the second indication information indicates that the terminal has permission to actively activate the GNSS measurement gap.

Optionally, the second indication information may be RRC signaling, or MAC CE, or DCI.

In some embodiments, the second indication information may include an information field for indicating that the terminal has the authority to activate the GNSS measurement gap.

To sum up, the method provided in this embodiment activates the GNSS measurement gap based on the indication of the network device by receiving the first indication information, and activates the GNSS measurement gap when the terminal meets the GNSS measurement conditions, so that the terminal actively activates the GNSS measurement gap, and enables the terminal to activate the GNSS measurement gap in different situations, thereby responding to the activation of the GNSS measurement gap and using the GNSS measurement gap to perform GNSS measurement.

Exemplarily, in response to the GNSS measurement gap being de-activated, the terminal stops GNSS measurement.

In some embodiments, before stopping the GNSS measurement, the terminal needs to deactivate the GNSS measurement gap. Optionally, the case where the terminal deactivates the GNSS measurement gap includes at least one of the following cases:

First, the terminal deactivates the GNSS measurement gap based on the instruction of the network device;

The second method is that the terminal actively deactivates the GNSS measurement gap.

First, a case where the terminal deactivates the GNSS measurement gap based on an instruction of the network device is described.

Please refer to FIG. 6, which is a flow chart of a GNSS measurement method provided by an embodiment of the present disclosure. This embodiment is illustrated by applying the method to a terminal device in the communication system shown in FIG. 1 or FIG. 2. The method may include the following steps:

Step 601: Receive third indication information.

The third indication information is used to indicate deactivation of the GNSS measurement gap.

In some embodiments, the third indication information is used to indicate deactivation of the GNSS measurement gap, or the third indication information is used to indicate the terminal to stop GNSS measurement, that is, the third indication information can directly indicate the terminal to deactivate the GNSS measurement gap, or can instruct the terminal to stop GNSS measurement so that the terminal deactivates the GNSS measurement gap.

Optionally, the third indication information may be RRC signaling, or MAC CE, or DCI.

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

The third information field is used to instruct deactivation of the GNSS measurement gap, that is, the network device directly instructs the terminal to deactivate the GNSS measurement gap. After receiving the third instruction information, the terminal can directly deactivate the GNSS measurement gap based on the third information field.

Optionally, the third information field is used to instruct the terminal to switch a pre-configured GNSS measurement gap to a deactivated state, thereby stopping GNSS measurement based on the deactivated GNSS measurement gap; or, the third information field is used to indicate a GNSS measurement gap that needs to be deactivated, so that the terminal stops GNSS measurement based on the deactivated GNSS measurement gap indicated by the third information field.

The fourth information field is used to instruct the terminal to stop GNSS measurement, that is, the network device instructs the terminal to stop GNSS measurement, and the terminal deactivates the GNSS measurement gap based on the GNSS measurement stop requirement indicated by the fourth information field. Optionally, the fourth information field is used to instruct the terminal to stop the GNSS measurement process.

In some embodiments, the third indication information may be actively sent by the network device to the terminal, or may be sent by the network device based on a deactivation request of the terminal.

In the case where the third indication information is sent by the network device based on a deactivation request of the terminal, the terminal sends a deactivation request to the network device before receiving the third indication information, wherein the deactivation request is used to request deactivation of the GNSS measurement gap.

Exemplarily, the terminal sending the deactivation request to the network device is implemented by the terminal sending an uplink media access control layer control signaling to the network device, wherein the uplink media access control layer control signaling includes the deactivation request.

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

Please refer to FIG. 7, which is a flow chart of a GNSS measurement method provided by an embodiment of the present disclosure. This embodiment is illustrated by applying the method to a terminal device in the communication system shown in FIG. 1 or FIG. 2. As shown in FIG. 7, the terminal actively deactivates the GNSS measurement gap, which may include the following steps:

Step 701, in response to the terminal completing the GNSS measurement, deactivating the GNSS measurement gap;

Step 702: In response to the terminal not having a GNSS measurement requirement, deactivate the GNSS measurement gap.
