Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of terminals 11 and a plurality of base stations 12.

Among them, the terminal 11 can be a device that provides voice and/or data connectivity to the user. The terminal 11 can communicate with one or more core network devices via a radio access network (RAN). The terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an Internet of Things terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user device, a user agent, a user device, or a user equipment (UE). Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 may be a vehicle-mounted device, such as a driving computer with wireless communication function, or a wireless communication device external to the driving computer. Alternatively, the terminal 11 may be a roadside device, such as a street lamp, signal lamp or other roadside device with wireless communication function.

The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network). Alternatively, an MTC system.

Among them, the base station 12 can be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station 12 can also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed units, DU). The centralized unit is provided with a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a media access control (Media Access Control, MAC) layer protocol stack; the distributed unit is provided with a physical (Physical, PHY) layer protocol stack. The specific implementation method of the base station 12 is not limited in the embodiment of the present disclosure.

A wireless connection can be established between the base station 12 and the terminal 11 through a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

In some embodiments, an E2E (End to End) connection may also be established between the terminals 11. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to Infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication.

In some embodiments, the wireless communication system may further include a network management device 13 .

Several base stations 12 are respectively connected to a network management device 13. The network management device 13 may be a core network device in a wireless communication system, for example, the network management device 13 may be a mobility management entity (MME) in an evolved packet core network device (EPC). Alternatively, the network management device may also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF) or a home subscriber server (HSS). The embodiment of the present disclosure does not limit the implementation form of the network management device 13.

In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

In the scenario of satellite communication, due to the long signal transmission distance between the signal transmitter and the signal receiver, data transmission takes a long time. For transmission with uplink and downlink relationship, the current standardization discussion has determined to introduce the offset Koffset parameter to compensate for the transmission delay in the satellite communication scenario. Generally, in the scenario of satellite communication, data transmission can be achieved by aligning the uplink and downlink timing on the base station side as shown in Figure 2, and by not aligning the uplink and downlink timing on the base station side as shown in Figure 3.

Koffset can be applied in various operations, such as: PUSCH transmission scheduled by DCI; transmission of HARQ feedback information and transmission of MAC CE, etc.

In the scenario of satellite communication, the UE needs to know its own location information in order to compensate for uplink synchronization. The UE can determine the UE's location information by performing GNSS measurement.

For IoT UE, the cellular mobile communication (cellular) module and the GNSS module are not currently supported to work simultaneously, that is, cellular mobile communication and GNSS measurement cannot be performed at the same time.

For IoT UE, the duration of GNSS position fix is determined by the UE itself, and the duration is related to the terminal's hardware conditions, channel environment, and moving speed.

The base station can trigger the UE to perform GNSS measurement. However, since the base station does not know or cannot obtain the GNSS status information of the UE in time, the triggering or periodic configuration of the base station may not match the GNSS status of the UE. The UE may perform invalid GNSS measurement, resulting in power consumption.

Therefore, how to reduce invalid GNSS measurements and reduce power consumption is an urgent problem to be solved.

As shown in FIG. 4 , this exemplary embodiment provides a positioning method, which may be performed by a UE, including:

Step 401: Determine the time information of the GNSS measurement according to the measurement configuration information;

Step 402: Determine whether to perform the GNSS measurement within the time range indicated by the time information according to an execution rule.

In a possible implementation manner, the UE may include: a UE that cannot perform cellular mobile communication and GNSS measurement simultaneously.

UE can be NB-IoT UE, eMTC UE or RedCap UE.

The UE can obtain the measurement configuration information by one of the following methods:

Communication protocol provisions;

Pre-stored in the UE;

Received from network-side devices such as access network devices.

The measurement configuration information may include, but is not limited to, time information of GNSS measurement. For example, the measurement configuration information may include indication information indicating the satellite navigation system adopted by the UE.

In one embodiment, the method further comprises:

The measurement configuration information is received.

Here, the access network device may indicate to the UE via measurement configuration information the execution time range of the GNSS.

In a possible implementation, the access network equipment includes but is not limited to: a base station in a terrestrial network.

In a possible implementation, the access network equipment includes but is not limited to: base stations and satellites in the NTN network.

The measurement configuration information may be determined by a core network device and transmitted to the UE via an access network device.

In one embodiment, the measurement configuration information is carried in:

Radio Resource Control (RRC) signaling; or

Media Access Control Element MAC CE; or

Physical layer signaling.

The UE performs GNSS measurement, which may include: determining the location information of the UE through a satellite navigation system.

In a possible implementation, the time range indicated by the time information includes but is not limited to at least one of the following:

a time window for performing the GNSS measurements;

The period for performing the GNSS measurements.

In a possible implementation manner, determining, according to an execution rule, whether to perform the GNSS measurement within a time range indicated by the time information includes:

According to the execution rule, it is determined whether to perform the GNSS measurement in the current time window. Here, the current time window may be a time window after the current moment and closest to the current moment.

The execution rule may be a rule on whether to perform GNSS measurement.

In a possible implementation manner, the execution rule may be determined according to the UE's demand for location information.

For example, if the UE does not need to determine its own location information within a predetermined time period, the UE may not perform GNSS measurement within the time range indicated by the time information.

For another example, if the UE has determined the location information, and the UE determines that the location information is valid for a predetermined time period, then the UE does not perform GNSS measurement. Here, the location information may be determined by the UE through at least one of the following: determined by base station positioning, and/or determined by a positioning method between UEs, and/or determined by historical GNSS measurements. The UE determines that the location information is valid for a predetermined time period, which may include but is not limited to at least one of the following: the UE does not move within the predetermined time period; the UE location information is determined to be valid within the predetermined time period based on the UE's moving speed.

In this way, the UE can determine whether to perform GNSS measurement within the time range configured by the measurement configuration information according to the execution rule, and no longer perform GNSS measurement within the time range configured by all measurement configuration information. On the one hand, the flexibility of performing GNSS measurement is improved, and on the other hand, invalid GNSS measurement can be reduced, reducing power consumption, which is an urgent problem to be solved.

As shown in FIG5 , this exemplary embodiment provides a positioning method, which may be performed by a UE, including:

Step 501: Receive trigger information, wherein the trigger information is used to trigger the UE to perform the GNSS measurement within a time range indicated by the time information.

In a possible implementation, the UE receives measurement configuration information sent by the access network device, and the UE can perform GNSS measurement within the time range indicated by the execution time information according to the measurement configuration information. Here, before performing GNSS measurement within the time range indicated by the execution time information, it is necessary to determine whether to perform GNSS measurement according to the execution rule.

In a possible implementation, the access network device may send trigger information to validate the measurement configuration information. That is, the trigger information may trigger the UE to perform GNSS measurement within the time range indicated by the execution time information according to the measurement configuration information. Here, the triggered GNSS measurement also needs to determine whether to perform GNSS measurement according to the execution rule.

In a possible implementation, the trigger information is used to trigger the UE to perform the GNSS measurement in a time window, wherein the time window includes a current time window. Here, the current time window may be a time window after the current moment and closest to the current moment.

In one embodiment, determining, according to an execution rule, whether to perform the GNSS measurement within a time range indicated by the time information includes:

In response to determining that the available duration of the current GNSS positioning information of the UE is greater than a predetermined duration threshold, not performing the GNSS measurement; or

In response to determining that the available time duration is less than or equal to a predetermined time duration threshold, performing the GNSS measurement.

In a possible implementation, the GNSS positioning information of the UE may be used to determine the timing deviation between the terminal and the network-side device.

Here, the time range indicated by the time information may include a most recent time window for performing GNSS measurement indicated by the time information.

In a possible implementation, not performing the GNSS measurement includes: not performing the GNSS measurement in the current time window. Here, the current time window may be a time window after the current moment and closest to the current moment.

The current GNSS positioning information may be determined by the UE through at least one of the following: through base station positioning, and/or through a positioning method between UEs, and/or through historical GNSS measurements.

The GNSS position fix information obtained by the UE has a usable duration. The validity of the GNSS position fix information can only be maintained for a period of time. After the usable duration, the GNSS of the terminal device times out. The UE needs to re-acquire the GNSS position fix information.

The predetermined duration threshold may be determined based on the UE's need for GNSS positioning information and/or the frequency with which the UE performs GNSS measurements.

For example, when the UE is stationary within the available duration, the UE may not need to perform GNSS measurement again. The predetermined duration threshold may be determined based on the stationary duration of the UE.

For another example, as shown in Figure 6, when the UE is required to perform multiple GNSS measurements within the available duration, the time range (including the time window) of the multiple GNSS measurements is within the available duration, and it is obvious that these GNSS measurements are invalid, so the UE may not perform one or more of the GNSS measurements. The predetermined duration threshold may be set based on the GNSS measurement frequency of the UE.

In one embodiment, the predetermined duration threshold is greater than or equal to a measurement cycle duration of the GNSS measurement, wherein the time range indicated by the time information includes the measurement cycle duration.

In a possible implementation, the measurement cycle duration includes: the cycle duration of the time window of the GNSS measurement indicated by the measurement configuration information.

In a possible implementation, the duration of the measurement cycle may be indicated by time information, that is, the time range indicated by the time information includes: the duration of the measurement cycle.

In a possible implementation, the measurement cycle duration may be determined based on the time range indicated by the time information. For example, the time range indicated by the time information includes multiple time windows, and the UE may determine the cycle duration of the time window based on the time window.

Exemplarily, as shown in FIG6 , the predetermined duration threshold is greater than or equal to the measurement cycle duration of the GNSS measurement, that is, there may be multiple GNSS measurements within the available duration of the current GNSS positioning information, and at least one GNSS measurement is an unnecessary measurement. Therefore, when the available duration of the current GNSS positioning information is greater than the predetermined duration threshold, the UE may determine not to execute the current GNSS.

In one possible implementation, in response to the predetermined duration threshold being greater than or equal to N times the measurement cycle duration, and the available duration of the current GNSS positioning information being greater than the predetermined duration threshold, the UE determines not to perform GNSS measurements for N-1 time windows.

As shown in FIG. 7 , this exemplary embodiment provides a positioning method, which may be performed by a UE, including:

Step 701: receiving configuration information indicating the execution rule;

or;

The execution rules are predefined.

In a possible implementation, the configuration information indicating the execution rule may be determined by the access network device and/or the core network device, and sent to the UE via the access network device.

In a possible implementation, the execution rule is predefined, and the predefined rule may include one of the following:

Regulations stipulated in the communication agreement;

Agreed upon by network-side equipment such as access network equipment and/or core network equipment and UE.

In a possible implementation, the UE may receive an execution rule of the access network device, the execution rule indicating whether the available duration of the GNSS position information exceeds a predetermined duration threshold, and when the UE determines that the available duration of its GNSS position information exceeds the predetermined duration threshold, the UE ignores the GNSS measurement operation in this GNSS measurement time window. Otherwise, the UE performs the GNSS measurement operation in this GNSS measurement window.

In a possible implementation, the execution rule is predefined, and the execution rule indicates whether the available time of the GNSS position information exceeds a predetermined time threshold. When the UE determines that the available time of its GNSS position information exceeds the predetermined time threshold, the UE ignores the GNSS measurement operation in this GNSS measurement time window. Otherwise, the UE performs the GNSS measurement operation in this GNSS measurement window.

As shown in FIG8 , this exemplary embodiment provides a positioning method, which may be performed by a UE, including:

Step 801a: In response to the UE completing the GNSS measurement within the time range, sending a first response message to the access network device; or

Step 801b: In response to the UE determining not to perform the GNSS measurement, sending a second response message to the access network device; or

Step 801c: In response to the UE determining not to perform the GNSS measurement, not sending GNSS assistance information associated with the GNSS measurement to the access network device within a feedback period associated with the time range.

In a possible implementation, the UE receives trigger information from the access network device to determine whether to perform GNSS measurement. When the UE performs this GNSS measurement based on the execution rule, the UE feeds back HARQ feedback information for the trigger instruction, for example, the first response information may use "ACK" to represent the execution of this GNSS measurement.

In one possible implementation, the first response information may include GNSS assistance information, and the GNSS assistance information may include but is not limited to at least one of the following: location information determined by performing GNSS measurement, and indication information indicating the duration of the location information.

As shown in Figure 9, when the UE does not perform this GNSS measurement based on the execution rule, the UE can feedback the second response information. For example, the second response information can use "NACK" to indicate that this GNSS measurement is not performed. When the access network device receives the "NACK" feedback for the trigger instruction, the access network device determines that the UE does not perform this GNSS measurement.

In a possible implementation, the UE does not perform this GNSS measurement based on the execution rule, and the UE does not feedback GNSS auxiliary information within a predefined feedback period after the GNSS measurement time window ends. When the access network device does not receive the GNSS auxiliary information sent by the UE within the predefined feedback period, the access network device determines that the UE does not perform this GNSS measurement.

As shown in FIG. 10 , this exemplary embodiment provides a positioning method, which may be performed by a UE and includes at least one of the following:

Step 1001: Send the first response information or the second response information on the transmission resources indicated by the trigger information, wherein the trigger information is used to trigger the UE to perform the GNSS measurement within the time range indicated by the time information.

In a possible embodiment, the trigger information used to indicate the transmission resource of the first response information or the second response information and the trigger information used to trigger the UE to perform the GNSS measurement within the time range indicated by the time information may be the same trigger information.

Here, the transmission resource of the first response information and/or the second response information can be indicated by the trigger information. As shown in Figure 9, the trigger information indicates the transmission resource of the first response information and/or the second response information while triggering the UE to perform the GNSS measurement. The base station can receive the first response information and/or the second response information on the transmission resource indicated by the trigger information, and correspond the first response information and/or the second response information to the performed GNSS measurement.

In a possible implementation manner, the measurement configuration information may also be used to indicate a transmission resource of the first response information and/or the second response information.

As shown in FIG. 11 , this exemplary embodiment provides a positioning method, which may be performed by access network identification, including:

Step 1101: Send measurement configuration information, wherein the measurement configuration information is used for a user equipment UE to determine time information for GNSS measurement, and to determine whether to perform the GNSS measurement within a time range indicated by the time information according to an execution rule.

In one embodiment, the execution rules include:

In response to determining that the available duration of the current GNSS positioning information of the UE is greater than a predetermined duration threshold, the UE does not perform the GNSS measurement; or

In response to determining that the available duration is less than or equal to a predetermined duration threshold, the UE performs the GNSS measurement.

In one embodiment, the predetermined duration threshold is greater than or equal to the measurement cycle duration of the GNSS measurement, wherein the time range indicated by the time information includes the measurement cycle duration.

As shown in FIG. 13 , this exemplary embodiment provides a positioning method, which may be performed by an access network device, including:

Step 1301: Send configuration information indicating the execution rule;

or;

The execution rules are predefined.

Regulations stipulated in the communication agreement;

Agreed upon by network-side devices such as access network equipment and/or core network equipment and UE.

As shown in FIG. 14 , this exemplary embodiment provides a positioning method, which may be performed by an access network device, including:

Step 1401a: receiving first response information, wherein the first response information is sent by the UE after completing the GNSS measurement within the time range; or

Step 1401b: receiving second response information, wherein the second response information is sent by the UE when it determines not to perform the GNSS measurement; or

Step 1401c: In response to not receiving the GNSS assistance information sent by the UE, determining that the UE does not perform the GNSS measurement.

When the UE performs the GNSS measurement based on the execution rule, the UE feeds back HARQ feedback information for the trigger instruction. For example, the first response information may use "ACK" to represent that the GNSS measurement is performed.

As shown in FIG. 15 , this exemplary embodiment provides a positioning method, which may be performed by an access network device, including at least one of the following:

Step 1501: Receive the first response information and/or the second response information on the transmission resources indicated by the trigger information, wherein the trigger information is used to trigger the UE to perform the GNSS measurement within the time range indicated by the time information.

A specific example is provided below in combination with any of the above embodiments:

This example provides a method for a terminal to skip GNSS measurement in a satellite communication system, thereby preventing the terminal from performing useless GNSS measurements and effectively reducing the power consumption of the terminal.

1. The terminal receives the measurement configuration information from the base station to determine the GNSS measurement configuration

a) The measurement configuration information includes time window information for the terminal to perform GNSS measurement, and the terminal performs GNSS measurement within the time window

b) The configuration information may be carried by RRC signaling, MAC CE or physical layer signaling

2. The terminal determines to skip GNSS measurement

a) When the terminal determines that a GNSS measurement needs to be performed based on the configuration information

b) The terminal determines whether to perform GNSS measurement operations within this GNSS measurement window based on execution rules (pre-defined or base station configuration)

In one implementation method, the terminal may receive an execution rule configured by the base station, and the execution rule is: whether the remaining GNSS positioning information available time exceeds a predetermined time threshold (pre-configured or pre-defined), when the terminal determines that its GNSS available time exceeds the predetermined time threshold, the terminal ignores the GNSS measurement operation in this GNSS measurement window. Otherwise, the terminal performs the GNSS measurement operation in this GNSS measurement time window.

In one implementation method, the terminal can be based on a predefined execution rule. The execution rule is: whether the remaining GNSS positioning information available time exceeds a predetermined time threshold (pre-configured or pre-defined). When the terminal determines that its GNSS available time exceeds the predetermined time threshold, the terminal ignores the GNSS measurement operation in this GNSS measurement window. Otherwise, the terminal performs the GNSS measurement operation in this GNSS measurement time window.

3. Terminal reporting indication information

a) The terminal reports indication information, where the indication information is used to indicate that the terminal skips GNSS measurement.

In one implementation method, as shown in FIG9 , the terminal receives a trigger instruction from the base station to determine that the GNSS measurement is to be performed. When the terminal ignores this GNSS measurement based on the above description, the terminal feeds back HARQ feedback information for the trigger instruction, such as "ACK" in the feedback information, i.e., the first response information indicates that the GNSS measurement is performed; "NACK" i.e., the second response information indicates that the GNSS measurement is not performed. When the base station receives the "NACK" feedback for the trigger instruction, the base station determines that the terminal does not perform the GNSS measurement.

In another implementation method, the terminal ignores this GNSS measurement based on the above description, and the terminal does not feedback GNSS auxiliary information within a predefined time (within the feedback period) after the end of the GNSS measurement time window. When the base station does not receive the GNSS auxiliary information sent by the terminal within the predefined time (within the feedback period), the base station determines that the terminal has not performed this GNSS measurement.

As shown in FIG. 16 , this exemplary embodiment provides a positioning device 110, which is applied to a user equipment UE and includes:

The processing module 110 is configured to determine time information of a global navigation satellite system GNSS measurement according to the measurement configuration information;
