The execution subjects involved in the embodiments of the present disclosure include, but are not limited to, artificial satellites that implement terrestrial cellular mobile communication network coverage, and user equipment such as mobile phone terminals that use cellular mobile communication network technology for wireless communication.

An application scenario of the embodiment of the present disclosure is that, as shown in FIG. 1 , the artificial satellite that realizes the coverage of the terrestrial cellular mobile communication network is a plurality of artificial satellites that revolve around the earth, such as an artificial satellite chain formed by artificial satellites spaced by a fixed distance along the same orbit. .

As the artificial satellite moves, the UE will be within the wireless signal coverage of different artificial satellites, that is, the UE will switch between the signal coverage of different artificial satellites.

Since the BWP configuration of each artificial satellite is different, the UE needs to switch between different BWPs. Currently, the fifth generation (5 ^th Gerneration) BWP switching mode cellular mobile communication technology is RRC signaling configuration or the DCI is configured, both with a time delay.

The configuration of BWP is relatively fixed for artificial satellites, that is to say, the sequence and frequency of BWP switching can be known in advance. .

As shown in FIG. 2 , this exemplary embodiment provides an information transmission method, and the information transmission method can be applied to an access network device of wireless communication, including:

Step 201: Send BWP configuration information, where the BWP configuration information is used to indicate parameters for switching between at least two BWPs.

The UE may be a mobile phone terminal or the like that uses a cellular mobile communication network technology to perform wireless communication. The access network device may be a mobile access network device. The mobile access network equipment may be a mobile base station of a cellular mobile communication network, such as an artificial satellite, a small base station carried by a high-altitude balloon, and the like. The BWP handover information can be sent by a network interface device of an access network such as a satellite providing cellular mobile communication network coverage or a small base station satellite carried by a high-altitude balloon.

Here, the BWP may be divided from the system bandwidth and used for the current communication bandwidth of the UE. The BWP can be divided based on the communication traffic volume of the UE. For a service with a large traffic volume, a BWP with a larger bandwidth can be divided into the UE, and for a service with a small traffic volume, a BWP with a smaller bandwidth can be divided into the UE. The BWP may include an uplink BWP and/or a downlink BWP.

Here, the artificial satellite that realizes the coverage of the terrestrial cellular mobile communication network can be a plurality of artificial satellites revolving around the earth, for example, an artificial satellite chain composed of artificial satellites spaced at a fixed distance along the same orbit.

Exemplarily, the artificial satellite may broadcast the BWP switching information by using a system message or the like, or may carry the BWP switching information through downlink signaling after the UE completes the initial access.

Here, the at least two BWPs may be at least two BWPs to be handed over by the UE. With the movement of artificial satellites. The UE needs to switch to a different BWP. The UE can switch from one BWP to another. At least two BWPs may belong to the same access network device, or may belong to different access network devices. At least two BWPs may also belong to the same cell, or belong to different cells.

Exemplarily, as the artificial satellite moves, the UE will be within the coverage of the radio signal beams of different artificial satellites, that is, the UE will switch between the beams of different artificial satellites; since the BWP configuration of each artificial satellite is different, the UE needs to Switch between different BWPs.

Here, the different BWPs may be BWPs with different bandwidths, and/or BWPs with different center frequencies, and/or BWPs with different cyclic prefix lengths, and the like.

For the artificial satellite chain, the order in which the beams of each artificial satellite cover the UE and the BWP configuration provided by each artificial satellite are relatively fixed. Therefore, the configurations of multiple BWPs that the UE may switch in sequence may be sent to the UE.

The configuration of the BWP may include the resource configuration of the BWP. The configuration of the BWP may also include the configuration of the characteristics of the BWP, such as subcarrier spacing.

The UE may activate the BWPs in sequence based on the configuration of the at least two BWPs, and perform data transmission on the activated BWPs.

In this way, the UE can obtain the configurations of multiple BWPs to be handed over at one time. On the one hand, the configuration of multiple BWPs to be handed over can be obtained at one time, which improves the information transmission efficiency and reduces the time when BWPs are instructed each time through RRC signaling or DCI. extension. On the other hand, reducing multiple BWPs requires signaling overhead generated by multiple RRC signaling or DCI indication.

In one embodiment, the parameters include at least one of the following:

a handover interval period corresponding to each of the at least two BWPs;

the activation moment of each of the BWPs in the at least two BWPs;

A switching sequence for switching between the at least two BWPs.

Here, the interval period of the BWP may be the duration of coverage of the UE for each BWP, and the UE may activate the BWP within the coverage duration of the BWP, and perform data communication on the activated BWP.

The interval period of the two BWPs may overlap, and the mobile access network device may configure the activation time of each BWP in the BWP handover information. The UE is activated based on the activation time of each BWP. For example, satellites can activate BWP when signal coverage is better to improve communication quality.

The UE may be based on the later BWP and activation time, and the handover period, the later BWP. When the BWP with the later time is activated, the BWP with the earlier time can be deactivated.

The BWP configuration information may indicate the switching sequence of each BWP, and the switching sequence of the BWPs may be determined based on the access network device to which the beams sequentially covering the UE belong. For example, based on the satellites that fly over the UE, the order of the BWPs of the respective satellites is determined as the order in which the UE switches the BWPs.

Here, at least two BWPs may belong to different access network devices. For example, the at least two BWPs may be BWPs of different satellites belonging to the same Starlink, respectively.

When the UE is in the beam coverage of different artificial satellites in the same star chain, the current BWP can be determined based on the indication of the BWP configuration information.

In this way, the UE determines multiple handover BWPs according to the BWP configuration information indication. On the one hand, the delay generated by each time the BWP is indicated by RRC signaling or DCI is reduced. On the other hand, reducing the signaling overhead generated by multiple RRC signaling or DCI indication for multiple BWPs

the frequency of each of the at least two BWPs;

the subcarrier spacing of each of the at least two BWPs;

The cyclic prefix CP length of each of the at least two BWPs.

For the service currently performed by the UE, the bandwidth of the BWP may be fixed, and the UE may determine the BWP based on the frequency point, and use the BWP for communication and transmission.

Here, the frequency point may be the center frequency point of the BWP, and the frequency domain position of the BWP may be determined by the center frequency point and the bandwidth of the BWP. The frequency point can also be the highest frequency point and/or the lowest frequency point of the BWP.

A BWP may contain multiple subcarriers that are continuous or non-consecutive, the configuration of the BWP may include subcarrier spacing, and the UE may determine that the BWP contains multiple subcarriers based on the subcarrier spacing, so that the subcarriers are used to carry data information.

The cyclic prefix (CP, Cyclic Prefix) is formed by copying the signal at the tail of the OFDM symbol to the head, and is used to make the time-delayed OFDM signal have an integer multiple period within the FFT integration period, which can simplify the signal processing complexity. The BWP handover information indicates the CP length, which is used for signal processing by the UE.

In one embodiment, the sending BWP configuration information includes:

Send high-layer signaling carrying the BWP configuration information.

Here, the mobile access network device may carry the BWP handover information through high-layer signaling, and the UE obtains the BWP configuration information through high-layer signaling. Thus, the flexibility of sending the BWP handover information is improved.

In one embodiment, as shown in Figure 3, the method further includes:

Step 202 : Send a handover command instructing the UE to switch BWPs, wherein the handover command indicates that the BWP to be handed over is different from the BWP indicated by the BWP configuration information.

Here, the switching command may be a dynamic switching command such as DCI. The handover command may instruct the UE to adopt a BWP other than the BWP indicated by the BWP handover information.

The resources occupied by the BWP indicated by the handover command and the BWP indicated by the BWP handover information are different. For example, the BWP indicated by the handover command and the BWP indicated by the BWP handover information may have different bandwidths, and/or activation times, and/or frequencies. , and/or subcarrier spacing, and/or CP length, etc.

Exemplarily, the artificial satellites in the artificial satellite chain can also use the dynamic BWP switching instruction to replace the instruction of the BWP switching information due to the change of the schedule. For example, the BWP switching information can be dynamically switched through the DCI. Indicates the handover of the BWP. The handover of the BWP indicated by the suspended BWP handover information may also be resumed.

Due to the different positions of the UE, the time that the UE occupies each BWP, etc., may be different. When the artificial satellite is networked, the corresponding management unit performs calculation and configuration parameter calculation to determine the activation time or switching period of each BWP of the UEde.

When the artificial satellite network changes, the BWP handover information can be re-determined, and the updated BWP handover information can be sent to the UE.

The beam direction of access network equipment such as artificial satellites is usually fixed. For example, the angle of the beam of the artificial satellite and the vertical line of the earth's center is fixed. Ground devices such as UEs can adjust the beam for reception or transmission based on the beam direction.

The mobile access network device sends beam indication information, which is used to indicate the beam direction of the beam to which each BWP belongs. Ground equipment such as the UE can adjust the beam based on the beam direction, and communicate based on the BWP configured by the BWP configuration information. By way of example, a ground device such as a UE may, according to the direction of the satellite beam, direct the beam obtained by beamforming to the artificial satellite for communication.

As shown in FIG. 4 , this exemplary embodiment provides an information transmission method, and the information transmission method can be applied to a user equipment UE of wireless communication, including:

Step 401: Receive and send BWP configuration information, where the BWP configuration information is used to indicate parameters for switching between at least two BWPs.

The UE may be a mobile phone terminal or the like that uses a cellular mobile communication network technology to perform wireless communication. The access network device may be a mobile access network device. The mobile access network equipment can be a mobile base station of a cellular mobile communication network, such as an artificial satellite, a small base station carried by a high-altitude balloon, and the like. The BWP handover information can be sent by a network interface device of an access network such as a satellite providing cellular mobile communication network coverage or a small base station satellite carried by a high-altitude balloon.

Here, the artificial satellite that realizes the coverage of the terrestrial cellular mobile communication network may be a plurality of artificial satellites revolving around the earth, for example, an artificial satellite chain composed of artificial satellites spaced by a fixed distance along the same orbit.

Here, the at least two BWPs may be at least two BWPs to be handed over by the UE. With the movement of artificial satellites. The UE needs to switch to a different BWP. The UE can switch from one BWP to another.

In one embodiment, as shown in Figure 5, the method further includes:

Step 402 : according to the parameter, switch between each of the at least two BWPs in sequence.

The UE may determine each BWP based on the received BWP configuration information, and then perform BWP handover.

The BWP configuration information may indicate the switching sequence of each BWP, and the switching sequence of the BWPs may be determined based on the access network device to which the beams sequentially covering the UE belong. For example, based on the satellites that fly over the UE, the order of the BWPs of the respective satellites is determined as the order in which the UE switches the BWPs

In one embodiment, the method further includes:

The sequentially activating each of the at least two BWPs includes:

The activation moment configured by the BWP configuration information may be calculated based on the premise that the UE does not move. Due to the movement of the UE, the relative position of the UE and the mobile access network device is offset from the relative position used for calculating the activation moment configured by the BWP configuration information.

The UE may determine the offset value of the activation moment based on its own motion. For example, when the UE and the mobile access network device move towards each other, the BWP needs to be activated in advance, therefore, an offset value can be set to advance the activation time. When the UE and the mobile access network equipment are in motion, the BWP can delay activation, therefore, an offset value can be set to delay the activation moment.

In this way, based on the relative position change between the UE and the mobile access network device, the activation time is adjusted so that the activation time can conform to the motion scene of the UE, so that the activation time is more accurate.

In one embodiment, the receiving BWP configuration information includes:

Receive high-level signaling carrying the BWP configuration information.

In one embodiment, the method further includes:

Exemplarily, the artificial satellite in the artificial satellite chain can also use the dynamic BWP switching instruction to replace the instruction of the BWP switching information due to the change of the schedule. For example, the BWP is dynamically switched through the DCI, and the BWP indicated by the DCI is activated. The handover of the BWP indicated by the BWP handover information may be suspended.

In one embodiment, the method further includes:

In response to deactivating the BWP indicated by the handover command to handover, the BWP indicated by the BWP configuration information is activated.

When the dynamic switching command is used to switch the BWP, the switching of the BWP indicated by the BWP switching information may be suspended. When the BWP indicated by the dynamic switching command is deactivated, the BWP indicated by the BWP configuration information may be restored, and the BWP indicated by the BWP configuration information may continue to be switched.

In one embodiment, the method further includes:

In response to performing RRC reconfiguration, the handover of the BWP indicated by the BWP configuration information is stopped.

In response to the UE performing RRC reconfiguration, the handover of the BWP indicated by the BWP handover information is stopped.

When the UE performs RRC reconfiguration, the UE may stop the handover of the BWP indicated by the current BWP handover information. The satellite may reconfigure the UE with new BWP handover information when the UE completes the RRC reconfiguration.

A specific example is provided below in conjunction with any of the above-mentioned embodiments:

1. As shown in Figure 1, it is assumed that the artificial satellite 1 configures and activates a BWP for the UE, and configures a semi-static activation configuration for the UE, that is, configures the BWP handover information;

2. The semi-static activation configuration includes BWP frequency point information, subcarrier spacing, and CP length.

3. High-level can also configure [valid time, period];

The information in 4 and 3 can be calculated and configured by the corresponding management unit when the artificial satellite is networked, and sent to the UE;

5. The UE in the connected state performs the BWP handover by performing the semi-static activation configuration according to the above configuration. The corresponding principle is the order of artificial satellites, the arrival time, the effective time of inter-satellite handover and activation of BWP frequency points are relatively fixed.

6. If the artificial satellite changes due to scheduling changes, the semi-static configuration can also be replaced by dynamic BWP switching, that is, the BWP can be dynamically switched through DCI, for example, BWP is deactivated. At this time, the previous semi-static activation configuration is suspended; the same It is also possible to continue the semi-static activation configuration, that is, reactivate the BWP configured in the semi-static activation configuration.

The procedures in 7 and 4 can also be cancelled by RRC reconfiguration.
