Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0188] In some embodiments, a very small aperture terminal (VSAT) antenna is used in a non-terrestrial network (NTN), and in future designs, the antenna can be changed from a VSAT to a phase array antenna, so that beamforming can be used for data transmission in the NTN network. Using beams can bring the following benefits:

[0189] 1. Based on different service requirements, more flexible beam scheduling is provided;

[0190] 2. Enhance coverage, get beamforming gain, change wide beam to narrow beam;

[0191] 3. Reduce interference and improve spectral efficiency.

[0192] In some embodiments, using beam hopping technology to solve the imbalance between supply and demand in the satellite coverage area is a research direction in the evolution of NTN. During the satellite scanning of a set of predefined beam hopping patterns, the activity time of the beam in different areas is different, thereby meeting the service requirements.

[0193] In some embodiments, referring to FIG. 1b, a schematic diagram of beam hopping is shown, and the dashed box is the signal range covered by the beam. The beam hopping technology can use all available satellite resources to provide services for specific locations or users. By adjusting the on-time and cycle of the beam, different capacity values are provided to balance the requirements of different beam coverage areas.

[0194] In some embodiments, referring to FIG. 1c, a schematic diagram of beam dwell time is shown. For an NTN system that uses beam hopping technology, the terminal needs to complete the access process within the dwell time of the current beam, otherwise it will cause an increase in latency and resource waste. Therefore, how to flexibly configure the dwell time of different beams to meet the different service time requirements of different beams without changing the ground network protocol is a problem that needs to be solved.

[0195] In some embodiments, when the beam is not in the current UE's wave position, the UE's behavior can refer to the discontinuous transmission (DTX) or discontinuous reception (DRX) mechanism in the R18 network energy saving (NES).

[0196] In some embodiments, during cell DTX, the UE does not expect to receive the following downlink channels or signals: dynamic scheduling new transmission of downlink control information (DCI) or DCI of certain format; semi-persistent scheduling physical downlink shared channel (SPS PDSCH); periodic or semi-persistent channel state information reference signal (CSI-RS).

[0197] In some embodiments, during cell DRX, the UE does not expect to transmit the following uplink channels or signals: uplink transmission corresponding to configured grant (CG); periodic or semi-persistent channel state information (CSI) reporting or sounding reference signal (SRS) transmission.

[0198] In some embodiments, referring to FIG. 1d, a schematic diagram of cell DTX mechanism is shown. The cell DTX or DRX mechanism configured, activated or deactivated by radio resource control (RRC) and dynamically activated or deactivated by DCI format 2-9 is introduced in NES.

[0199] In some embodiments, in the NES indication mechanism, DCI format 2-9 cannot dynamically indicate the change of cell DTX or DRX, but only indicates whether the current RRC configured pattern is dynamically activated.

[0200] In some embodiments, since the beam illumination condition may need to change dynamically with the number of UEs or data volume in different beams, the dwell time of each beam does not necessarily need to be equal, and a more flexible configuration or dynamic indication mechanism can be designed to allow the beam illumination condition to change quickly and dynamically.

[0201] In some embodiments, the granularity of the beam lighting is preferably 5 ms or 10 ms (assuming that SIB1 and SIB19 are transmitted within the remaining 5 ms), otherwise resource fragmentation will occur, i.e. the beam lighting time cannot start with a candidate resource that can transmit a synchronization signal block (SSB, Synchronization Signal and PBCH block), resulting in the terminal that has not accessed the network during the beam lighting time being unable to synchronize downlink, reducing efficiency; at the same time, it may cause a large overhead of dynamically indicating the beam lighting time. Please refer to FIG. 1e, which shows the problem caused by irregular lighting.

[0370] FIG. 5a is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 5a, the embodiment of the present disclosure relates to a communication method, which is used for the communication system 100, and the method includes one of the following steps:

[0371] Step S5101: The network device sends first information to the terminal.

[0372] In some embodiments, the first information is used to indicate the first time for the terminal to perform listening.

[0373] In some embodiments, the optional implementation of step S5101 can refer to the optional implementation of step S2102 in FIG. 2a and other associated parts in the embodiments involved by FIG. 2a, which will not be repeated here.

[0374] In some embodiments, the above method can include the method of the above terminal side, network device side, and other embodiments, which will not be repeated here.

[0375] In order to better understand the embodiments of the present disclosure, the following will be further described through some exemplary embodiments:

[0376] The embodiments of the present disclosure provide a beam hopping mechanism that can be dynamically changed or flexibly configured (because it can be dynamically indicated), which can adapt to different service requirements of different services or beam positions, and can achieve the above effects with minimal signaling overhead (bitmap indication).

[0377] In some embodiments, a new DCI format is provided, or an existing DCI format 2-9 of NTN is reused.

[0378] In some embodiments, each block of DCI corresponds to one cell, and the starting position of the corresponding block of the footprint of one beam can be indicated by the positionInDCI-beamhopping parameter.

[0379] In some embodiments, each block contains a corresponding bitmap, and the length N is explicitly configured by RRC or implicitly determined by the granularity (ms) indicated by each bit.

[0380] In some embodiments, the bitmap has a corresponding association period, which can be the SSB Periodicity indicated in SIB1, or can be configured by SIB19 or RRC, assuming the period is M (ms).

[0381] In some embodiments, the granularity of the corresponding beam is M / N (bitmap length is explicitly configured).

[0382] In some embodiments, the granularity is explicitly configured by SIB19 or RRC, then the bitmap length can be obtained.

[0383] In some embodiments, the DCI can be group common DCI, i.e. the corresponding monitoring parameters are configured by type 3 CSS.

[0384] In some embodiments, the DCI has a new RNTI, such as NTN-beamhopping-RNTI.

[0385] In some embodiments, the bitmap is indicated in a cyclic manner over multiple association periods.

[0386] In some embodiments, the DTX or DRX of the cell is configured based on the configuration of SIB19 or RRC.

[0387] In some embodiments, the enhancement mechanism for configuring the OnDuration timer is that multiple OnDuration times can be configured in each period, and each OnDuration time can not be equal.

[0388] In some embodiments, according to the relevant configuration mechanism, multiple sets of DTX or DRX configurations can be configured for the same beam, and the final OnDuration time takes their union.

[0389] Another enhancement mechanism is for UE behavior:

[0390] In some embodiments, in the non-onduration time, the UE does not expect to send or receive any UL or DL signal.

[0391] In some embodiments, for new design DCI or DCI format 2-9, UE monitors the CSS of type 3, even if the current corresponds to non-active time, if the corresponding DCI format 2-9 is received, the understanding of the beam hopping scheme is updated after the processing time.

[0392] In some embodiments, an on-demand UE indication mechanism can be considered, i.e., the UE reports the corresponding beam hopping configuration it expects, and the indication method can reuse the bitmap mechanism indicated in the above DCI, but the base station can confirm or reconfigure the corresponding beam hopping mechanism.
