Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable.

For ease of understanding, some of the contents of the embodiments of the present application are described below:

1. NTN system.

In the 5G era and the subsequent 6G era, the disadvantages of the ground network in terms of large-scale intensive deployment and energy consumption can be exactly remedied by the NTN system, and the advantages of satellite communication in terms of coverage, reliability and flexibility can remedy the defects of ground mobile communication.

Fig. 2 and 3 are schematic diagrams of two typical micro communication networks. Fig. 2 is a schematic network diagram of a Non-terrestrial network typical scenario (Non-terrestrial network based on a transparent payload), as shown in fig. 2, and fig. 3 is a schematic network diagram of a Non-terrestrial network typical scenario (Non-terrestrial network based on a regenerated payload), as shown in fig. 3.

Wherein, for the Transparent payload, the satellite does not change the received signal, and only amplifies and forwards the received signal; for a regenerating payload, the satellite has some or all of the functionality of the base station. In fig. 2 and 3, the satellite will cover a certain area through several beams, and the beam coverage area is elliptical. Alternatively, the satellite may also be referred to as a high altitude platform.

Alternatively, for Non-geostationary orbit satellites (Non-GEO), since the satellites are in motion relative to the earth, the relative positions of the satellites and the earth may change over time, thereby causing the coverage of the satellites to change. For this case, two different modes are designed: cell coverage is fixed on the ground (earth fixed cells) and cell coverage is mobile on the ground (earth moving cells). For earth fixed cells, we do not change the coverage area of the satellite on the ground by adjusting the orientation of the antenna of the satellite as the satellite moves. For earth moving cells, the terrestrial coverage area of the satellite moves as the satellite moves.

In a Terrestrial Network (TN), there is also multi-beam coverage, but only one beam can be used for transmission at the same time in the same cell, and the same frequency band is used between all beams. In an NTN system, however, all beams of a satellite may operate simultaneously, and different beams may operate on different frequency resources.

The beam measurement method in the NTN scenario provided in the embodiments of the present application is described in detail below with reference to the drawings and some embodiments and application scenarios thereof.

In some embodiments, the network side device is a satellite having a base station function, and at this time, the network side device may directly send the first signaling to the terminal through the NTN network. In some embodiments, the network-side device is a base station, and may send the first signaling to the satellite, and then the satellite forwards the first signaling to the terminal through the NTN network.

It should be noted that the sending manner of the first signaling may be set according to actual needs, for example, in some embodiments, the first signaling is carried by at least one of the following: radio Resource Control (RRC), media Access Control Element (MAC CE), and Downlink Control Information (DCI).

The third BWP configuration information for a cell may include part of the configuration parameters that are the same: among the plurality of third BWP configuration information for one cell, partial configuration parameters of any two third BWP configuration information are the same. The plurality of third BWP configuration information may be understood as BWP configuration information corresponding to different time domains, or may be understood as BWP configuration information corresponding to different beams, terminals, or BWPs.

When the second measurement beam set is determined based on the location information of the terminal, a beam whose coverage area includes the location of the terminal and a beam whose coverage area edge is close to the location of the terminal may be determined as the second measurement beam set.

According to the embodiment of the application, the auxiliary information is reported through the terminal, so that the network side equipment can better determine the second measurement beam set suitable for the terminal based on the reported auxiliary information.

Further, in some embodiments, the first configuration information further includes configuration information of an associated reference signal.

In the embodiment of the present application, the Reference Signal may include a Synchronization Signal block (Synchronization Signal and PBCH block SSB), a Channel State Information Reference Signal (CSI-RS), and the like.

For better understanding of the present application, the following detailed description is given to the procedure of beam measurement performed by the first signaling activation terminal sent by the network side device, by using some specific examples:

the first embodiment is as follows: and the network side equipment determines to configure a beam set which needs to be measured for the terminal according to the position information of the terminal.

As shown in fig. 5, the network-side device configures, according to the location information of the terminal, a beam set that needs to be measured into { beam 1, beam 2, beam 3} for the terminal through the first signaling, and the corresponding BWP information is { BWP 1, BWP 2, BWP3}. Wherein beam 1 corresponds to BWP 1, beam 2 corresponds to BWP 2, and beam 3 corresponds to BWP 3.

The terminal is switched to three BWPs in sequence to complete beam measurement, and the measurement result is fed back to the base station, and the network side equipment can obtain the transmission performance of each beam through the measurement feedback result received on different BWPs and the feedback information of the terminal.

Example two: different beams have different polarization information.

As shown in fig. 6, according to the location information of the terminal, the network side device configures a beam set to be measured for the terminal through the first signaling as { beam 1, beam 2}, and the corresponding antenna polarization information is { right hand polarization, left hand polarization }, where beam 1 corresponds to right hand polarization (RHCP) and beam 2 corresponds to left hand polarization (LHCP).

The terminal completes beam measurement by adjusting the polarization direction of the receiving antenna, feeds back the measurement result to the base station, and feeds back the information and the network transmission performance through the terminal.

In the third embodiment, different beams have different polarization information and different BWPs.

As shown in fig. 7, according to the location information of the terminal, the network-side device configures a beam set to be measured for the terminal as { beam 1, beam 2, beam 3} through the first signaling, the corresponding antenna polarization information is { right-hand polarization, left-hand polarization }, and the corresponding BWP information is { BWP 1, BWP 2, BWP3}. Wherein beam 1 corresponds to right-handed polarization and BWP 1, beam 2 corresponds to left-handed polarization and BWP 2, and beam 3 corresponds to left-handed polarization and BWP 3.

Optionally, in some embodiments, BWP 1, BWP 2, and BWP3 are dynamically configured by the network-side device.

In the fourth embodiment, different beams have different polarization information and different BWPs.

As shown in fig. 7, according to the location information of the terminal, the network device configures a beam set to be measured for the terminal as { beam 1, beam 2, beam 3} through the first signaling, the corresponding antenna polarization information is { right-hand polarization, left-hand polarization }, and the corresponding BWP information is { BWP 1, BWP 2, BWP3}. Wherein beam 1 corresponds to right-handed polarization and BWP 1, beam 2 corresponds to left-handed polarization and BWP 2, and beam 3 corresponds to left-handed polarization and BWP 3.

BWP 1 is the BWP dedicated to measurement in beam 1, BWP 2 is the BWP dedicated to measurement in beam 2, and BWP3 is the BWP dedicated to measurement in beam 3.

Fifth, different beams have different polarization information and different reference signals.

Wherein beam 1 corresponds to right-handed polarization, BWP 1 corresponds to reference signal 1, beam 2 corresponds to left-handed polarization, BWP 1 corresponds to reference signal 2, and beam 3 corresponds to left-handed polarization, BWP 1 corresponds to reference signal 3.

Optionally, the BWP 1 is a BWP dedicated to beam measurement in a cell.

And in the sixth embodiment, the terminal determines the beam to be measured based on the position of the terminal.

As shown in fig. 8, when the terminal is at location a, it requests to perform beam measurement, the network side device sends a first signaling to activate the terminal to perform beam measurement, the beam to be measured is configured for the terminal as { beam 1, beam 2, beam 3}, the corresponding antenna polarization information is { RHCP, LHCP }, and the corresponding BWP information is { BWP 1, BWP 2}. Because the propagation delay in the NTN scene is very large, when the terminal receives the first signaling, the terminal has moved from position a to position B, and at this time, the terminal only performs beam measurement on beam 1 and beam 2 according to its own position information.

Seventh embodiment, the terminal determines the beam to be measured based on the measurement duration.

As shown in fig. 9, the network side device configures, through the first signaling, a beam set to be measured for the terminal as { beam 1, beam 2, beam 3}, and time-domain positions of configured reference signals { reference signal 1, reference signal 2, reference signal 3}, effective time information of beam measurement, and measurement duration are as shown in fig. 9, and for beam 3 corresponding to reference signal 3, the terminal does not perform measurement.
