In an internet of things (Internet of Things, ioT)/machine type communication (Machine Type Communication, MTC) MTC Non-terrestrial network (Non-terrestrial Network, NTN) system, a UE needs to frequently receive GNSS signals to determine location information of the UE for determining Timing Advance (TA) during communication. Due to UE capability limitations, the UE cannot perform cellular network (cellular) operation and GNSS signal reception at the same time. Moreover, for the reception of the GNSS signal, the UE may start the GNSS module to receive the GNSS signal through a hot start or a cold start. If the GNSS module is turned on by the UE in a hot start mode, the UE can complete the reception of the GNSS signal in a short time, for example, 1 second or 2 seconds. If the GNSS module is turned on in the cold start mode, the UE needs to turn on the components in the GNSS module step by step, and may take a long time to complete receiving the GNSS signal, for example, 1 minute or 2 minutes. The UE is unable to perform cellular network operations during reception of the GNSS signals.

Therefore, how to coordinate the receiving of the GNSS signals and the communication of the cellular network according to the different opening modes of the GNSS module in the process of receiving the GNSS signals by the UE, so as to improve the communication stability of the UE is a problem to be solved.

As shown in fig. 2, the present exemplary embodiment provides an information transmission method, which may be performed by a UE, including:

step 201: and sending capability information of the UE to network side equipment, wherein the capability information is used for indicating a mode of receiving GNSS signals by the UE, the capability information is used for determining first configuration information by the network side equipment, and the first configuration information is used for receiving the GNSS signals by the UE.

In one possible implementation, the network-side device includes, but is not limited to, at least one of: access network equipment such as a base station; a wire-net device.

In one possible implementation, the network-side device may be a network-side device of an NTN network

In one possible implementation, the UE includes, but is not limited to, at least one of: and the UE is communicated based on the NTN network and the ground network.

Illustratively, the UE is a UE that communicates based on an NTN network. As the locations of the UE and satellites change continuously, the UE needs to frequently determine the location of the UE for determining the TA during communication.

In one possible implementation, the GNSS signals include, but are not limited to, positioning signals for satellite-based positioning.

The network side device may receive capability information sent by the UE while maintaining a connection state with the UE.

In one possible implementation, the capability information is carried in an RRC message.

The UE may send capability information to the network side device in the RRC connected state.

The manner in which the UE receives the GNSS signal may be predetermined or may vary according to the actual state of the UE.

In one possible implementation, the time period required for the UE to receive GNSS signals in different ways is different.

Exemplary ways in which the UE receives GNSS signals include, but are not limited to, at least one of: the UE cold starts a GNSS module and receives the GNSS signals; the UE thermally activates the GNSS module and receives the GNSS signals.

After the network side device receives the capability information, the first configuration information of the GNSS signal received by the UE can be determined based on the manner in which the GNSS signal is received by the UE.

In one possible implementation, the first configuration information is used to indicate, but is not limited to, a resource configuration for the UE to receive GNSS signals.

For example, the first configuration information may be associated with a gap (gap) in which the UE receives the GNSS. During the gap, the UE only performs GNSS signal reception and does not perform any mobile cellular network (cell) related operations, i.e., the UE does not need to perform signal reception/signal transmission operations on the serving cell.

Thus, through the capability information, the UE may indicate to the network side device a manner in which the UE receives the GNSS information, and the network side device may determine the manner in which the UE receives the GNSS signals. The network side equipment can determine the state of the UE, and configuration errors and other conditions generated by the fact that the network side equipment does not determine the mode adopted by the UE to receive the GNSS signals are reduced. Based on the first configuration information, the UE may receive GNSS information. Since the first configuration information is set based on the capability information, the UE's need to receive GNSS signals may be configured. On the one hand, the accuracy of the first configuration information configured by the network side equipment can be improved, and the waste of resources is reduced. On the other hand, the success rate of receiving GNSS signals by the UE can be improved, and the positioning success rate is further improved.

Here, the UE may receive GNSS signals in at least two ways. And the two ways of receiving GNSS signals require different durations. The UE may indicate to the network side device the manner in which the UE is employed through the capability information.

In one possible implementation, the first time period required for receiving the GNSS signal by the first mode or the second time period required for receiving the GNSS signal by the second mode may be predetermined or may be predetermined. The first duration corresponding to the first mode and/or the second duration corresponding to the second mode of the pair of communication protocols or the like may be pre-agreed or may be pre-agreed.

Therefore, through the capability information, the network side equipment can determine that the UE receives the GNSS signals in the first mode or the second mode, further determine the time length required by receiving the GNSS, improve the accuracy of configuring the first configuration information, and improve the success rate of positioning the UE through the GNSS information.

receiving the duration of the gap of the GNSS signals;

the period of the gap;

offset of the gap.

After the network side device receives the capability information, the first configuration information of the GNSS signal received by the UE can be determined based on the manner in which the GNSS signal is received by the UE, that is, by adopting a first manner or a second manner.

The first configuration information is associated with a gap (gap) in which the UE receives the GNSS. During the gap, the UE only performs GNSS signal reception and does not perform any mobile cellular network (cell) related operations, i.e., the UE does not need to perform signal reception/signal transmission operations on the serving cell.

In one possible implementation, if the UE receives GNSS signals in the first manner, the gap time period is longer than the first duration. If the UE receives the GNSS signals in the second manner, the gap time period is longer than the second time period.

For example, if the network side device determines that the UE receives the GNSS signal in the first manner, the network side device may configure the gap duration with a shorter duration. And the network side equipment determines that the UE receives the GNSS signals in the second mode, and can configure the gap duration with longer duration.

In one possible implementation, the network side device may determine a period of the slot, an offset of the slot, and the like based on the configured slot duration.

In one possible implementation, the offset of the gap may be an offset of the gap starting position.

For example, for longer duration gaps, the network side device may configure a longer slot cycle for the UE.

Therefore, through the capability information, the network side equipment can determine the corresponding time slot configuration based on the mode of receiving the GNSS signals by the UE, so that the time slot configuration can meet the requirements of different GNSS signal receiving modes, and further positioning based on the GNSS signals can be realized.

And/or, the period of the gap is an update period of the GNSS.

The UE needs to complete the reception of the GNSS signal within the duration of the gap configured by the network side device, and therefore, the duration of the gap needs to be greater than or equal to the duration required by the UE to receive the GNSS signal.

The network side device can configure the gap period based on the required updating period of the GNSS, so that the requirement of the updating period of the GNSS on the position information can be met.

Here, the update period of the GNSS may include: update period of UE location information.

As shown in fig. 3, the present exemplary embodiment provides an information transmission method, which may be performed by a UE, including:

step 301: and receiving the first configuration information sent by the network side equipment.

In one possible implementation, the indication of the first configuration information may be carried in an RRC message and sent by the network side device to the UE.

For example, the network side device configures, through an RRC message, gap configuration information (first configuration information) of the UE when receiving the GNSS signal, where the first configuration information indicates at least one of: gap duration (T); and a repetition Period (gap_period) of Gap, and an offset (offset) of Gap. During gap, the UE only receives GNSS signals and does not perform any cell related operations, i.e. the UE does not need to perform reception/transmission operations on the serving cell. Wherein T should be greater than or equal to the time corresponding to type1 or type2, and gap_period should be the Period of GNSS update.

As shown in fig. 4, the present exemplary embodiment provides an information transmission method, which may be performed by a UE, including:

step 401: and when the capability information of the UE indicates that the UE adopts the second mode, receiving second configuration information sent by the network side equipment, wherein the second configuration information is used for the UE to start an RRC reestablishment process or initiate initial access.

If the UE receives the GNSS signal in the second manner, for example, in a manner of using a cold start GNSS module, the second period of time required for the UE to receive the GNSS signal is longer, and the UE may be out of step with the serving cell, or in an NTN scenario, the UE may leave the serving cell due to movement of a satellite, etc. Therefore, the network side device may send the second configuration information to the UE for the UE to access the target cell. The second configuration information may include at least information necessary for the UE to access the target cell, such as: identification of the target cell; target cell frequency band information, etc.

In one possible implementation, the network-side device may send the second configuration information to the UE before a time slot in which the UE receives the GNSS signals.

And the UE initiates an initial access flow to access to the target cell according to the second configuration information.

In one possible implementation, the second configuration information may be carried in an RRC message sent by the network side device to the UE.

In one possible implementation, after the UE receives the timeslot of the GNSS signal, the UE is out of step with the serving cell due to the long duration of the timeslot, and the UE may initiate an RRC reestablishment procedure to reestablish an RRC connection with the serving cell.

In this way, the situation that the UE cannot access the cell after receiving the GNSS signal can be reduced.

When the UE is in an NTN network scenario, the relative position of the UE and the serving cell (including static cell, semi-static cell and/or dynamic cell) may change as the satellite and/or the UE moves, so that the UE may leave the serving cell. The network side device may determine, in advance, whether the UE leaves the current serving cell after receiving the GNSS signal according to the relative motion state of the UE and the serving cell, so as to determine whether to send second configuration information to the UE.

For example, if the network side device determines to receive the GNSS signal by using the cold start GNSS module, and determines that the UE may leave the coverage area of the signal of the current serving cell after the UE completes receiving the GNSS signal according to the relative movement between the serving cell of the UE and the UE, the network side device may send the second configuration information to the UE.

As shown in fig. 5, the present exemplary embodiment provides an information transmission method, which may be executed by a network side device, including:

step 501: and receiving capability information sent by the UE, wherein the capability information is used for indicating the way in which the GNSS signals are received by the UE.

Thus, through the capability information, the network side equipment can determine the GNSS receiving mode of the UE, and misjudgment caused by the fact that the network side equipment does not determine the GNSS receiving mode of the UE is reduced.

As shown in fig. 6, the present exemplary embodiment provides an information transmission method, which may be executed by a network side device, including:

step 601: and determining first configuration information according to the capability information, wherein the first configuration information is used for the UE to receive GNSS signals.

receiving the duration of the gap of the GNSS signals;

the period of the gap;

offset of the gap.

and/or, the period of the gap is an update period of the GNSS.

The cold start GNSS module may include, but is not limited to, at least one of: powering up the GNSS module again; reconfiguring the GNSS module; resetting the GNSS module.

The hot-start GNSS module may include, but is not limited to, at least one of: revalidate the configured GNSS module; and waking up the GNSS module in the sleep state.

The time required for cold start of the GNSS module is longer than the time required for hot start of the GNSS module. Thus, the UE may warm start the GNSS module and receive the GNSS signal for a first duration that is less than a second duration that the GNSS module is cold started and receives the GNSS signal.

The capability information may be carried in different RRC fields.

Illustratively, the Information Element (IE) may be as follows: the NTN-Parameters-NB introduces indication information (capability information) of a type of a manner of receiving the GNSS signals supported by the UE, and if the indication information is "type 1 (type 1)", which indicates that the UE can start the GNSS module to receive the GNSS signals in a hot start manner, the network side device may determine that the UE can complete the GNSS signal reception in a shorter time, for example, 1 second or 2 seconds. If the indication message is "type 2", which indicates that the UE can start the GNSS module to receive the GNSS signal in a cold start manner, the network side device may determine that the UE needs a long time to complete the GNSS signal reception, for example, 1 minute or 2 minutes.

Illustratively, at IE: the NTN-Parameters introduces indication information (capability information) of a type of a manner of receiving the GNSS signals supported by the UE, and if the indication information is "type 1", which indicates that the UE can start the GNSS module to receive the GNSS signals in a hot start manner, the network side device may determine that the UE can complete the GNSS signal reception in a shorter time, for example, 1 second or 2 seconds. If the indication message is "type 2", which indicates that the network side device can determine that the UE can start the GNSS module to receive the GNSS signal in a cold start manner, the UE needs to complete the GNSS signal reception for a long time, for example, 1 minute or 2 minutes.

Thus, through the capability information, the network side device may determine the manner in which the UE receives the GNSS signal, i.e. the cold start GNSS module or the hot start GNSS module, and configure the first configuration information, such as the gap duration, based on the cold start GNSS module or the hot start GNSS module. On the one hand, the accuracy of the first configuration information configured by the network side equipment can be improved, and the waste of resources is reduced. On the other hand, the success rate of receiving GNSS signals by the UE can be improved, and the positioning success rate is further improved.

As shown in fig. 7, the present exemplary embodiment provides an information transmission method, which may be executed by a network side device, including:

Step 701: and sending the first configuration information to the UE.

As shown in fig. 8, the present exemplary embodiment provides an information transmission method, which may be executed by a network side device, including:

step 801: and when the capability information of the UE indicates that the UE adopts the second mode, sending second configuration information to the UE, wherein the second configuration information is used for the UE to start an RRC reestablishment process or initiate initial access.

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

1. introducing UE capability indication information (a first mode), and indicating mode type information (i.e. indicating a first mode or a second mode) of the UE for receiving GNSS signals to a network through an RRC message;

illustratively, the Information Element (IE) may be as follows: the NTN-Parameters-NB introduces indication information (capability information) of a type of a manner of receiving the GNSS signals supported by the UE, and if the indication information is "type 1 (type 1)" (first manner) indicating that the UE can start the GNSS module to receive the GNSS signals in a hot start manner, the network side device may determine that the UE can complete the GNSS signal reception in a shorter time, for example, 1 second or 2 seconds. If the indication message is "type2" (the second mode), which indicates that the UE can start the GNSS module to receive the GNSS signal in the cold start mode, the network side device may determine that the UE needs to complete the GNSS signal reception for a long time, for example, 1 minute or 2 minutes.

Illustratively, at IE: the NTN-Parameters introduces indication information (capability information) of a type of a manner of receiving the GNSS signals supported by the UE, and if the indication information is "type 1" (first manner), which indicates that the UE can start the GNSS module to receive the GNSS signals in a hot start manner, the network side device may determine that the UE can complete the GNSS signal reception in a shorter time, for example, 1 second or 2 seconds. If the indication message is "type 2" (second mode), it indicates that the network side device may determine that the UE can start the GNSS module to receive the GNSS signal in the cold start mode, and the UE needs to complete the GNSS signal reception for a long time, for example, 1 minute or 2 minutes.

2. According to the UE reporting capability indication information, the network configures corresponding gap configuration information for the UE;

for example, the network side device configures, through an RRC message, gap configuration information (indicating first configuration information) of the UE when receiving the GNSS signal, where the configuration information includes at least one of: gap duration (T); a repetition Period (gap_period) of the Gap, and a start position (offset) of the Gap. During gap, the UE only receives GNSS signals and does not perform any cell related operations, i.e. the UE does not need to perform reception/transmission operations on the serving cell. Wherein T should be greater than or equal to the time corresponding to type1 or type2, and gap_period should be the Period of GNSS update.

3. If the UE reports the capability indication information of the type 2, configuring corresponding configuration of a target cell to the UE according to the NTN network type if necessary;

for example, if the NTN network type is the earth-fixed type, after the UE completes GNSS reception, the UE and the serving cell are out of step due to the excessively long gap time, and the UE starts the RRC reestablishment procedure.

For example, if the NTN network type is the earth-fixed type, the network configures the target cell configuration (second configuration information) of the target cell through the RRC message, and the UE initiates an initial access procedure according to the target cell configuration information to access the target cell.
