The continuous emergence of new internet applications such as augmented Reality (Augmented Reality, AR), virtual Reality (VR), and vehicle-to-vehicle communications has put higher demands on wireless communication technologies, driving the continuous evolution of wireless communication technologies to meet the demands of the applications. Cellular mobile communication technology is in the evolution phase of the new generation technology. An important feature of the new generation of technology is the flexible configuration that supports multiple service types. As different service types have different requirements for wireless communication technologies, for example, the main requirements of the enhanced mobile bandwidth (Enhanced Mobile Broadband, eMBB) service types are focused on the aspects of large bandwidth, high rate and the like; the main requirements of high reliability and low latency communication (Ultra-reliable and Low Latency Communications, URLLC) traffic types are focused on higher reliability and low latency; the main requirements of large-scale machine type communication (Massive Machine Type Communication, mctc) traffic types are focused on large connection numbers. Accordingly, new generation wireless communication systems require flexible and configurable designs to support the transmission of multiple traffic types.

In the research of wireless communication technology, satellite communication is considered as an important aspect of future development of wireless communication technology. Satellite communication refers to communication by a radio communication apparatus on the ground using a satellite as a relay. The satellite communication system is composed of a satellite part and a ground part. The satellite communication is characterized in that: the communication range is large; communication can be performed from any two points as long as the communication is within the range covered by the electric wave emitted by the satellite; is not easily affected by land disasters (high reliability). Satellite communications, as a complement to current terrestrial cellular communications systems, may have the following benefits: extension covering: for areas with high cost, such as ocean, desert, remote mountain areas and the like, which cannot be covered by the current cellular communication system, the problem of communication can be solved through satellite communication. Emergency communication: in extreme cases where disasters such as earthquakes and the like have occurred that render the infrastructure for cellular communications unusable, a communication connection can be established quickly using satellite communications. Industry applications are provided: for example, for long-distance transmission delay sensitive services, the delay of service transmission can be reduced by satellite communication. It is expected that in future wireless communication systems, the satellite communication system and the terrestrial cellular communication system will gradually achieve deep convergence, and truly achieve intelligent networking.

In some embodiments, in the satellite communication scenario, there is a longer signal transmission distance between the transmitting end and the receiving end, resulting in a longer time for data transmission. For transmission with uplink and downlink relation, it is determined that the terminal needs to compensate propagation delay based on the configuration of the base station. Compensating for propagation delay may be applied in a variety of operations, e.g., physical uplink shared channel (PUSCH, physical Uplink Shared Channel) transmission scheduled by downlink control information (DCI, downlink Control Information); transmission of hybrid automatic repeat request (HARQ, hybrid Automatic Repeat reQuest) feedback information, transmission of medium access control elements (MAC CEs ), and the like. Please refer to fig. 1b, which is a scenario of uplink and downlink timing alignment at the base station side; please refer to fig. 1c, which is a scenario in which uplink and downlink timing at the base station side are not aligned.

In some embodiments, the terminal needs to acquire location information to determine timing compensation information for uplink transmissions. The terminal may determine its own location information through the GNSS measurement module. For IoT terminals, the cell (GNSS) module may not be supported to operate simultaneously and only intermittent transmissions may be supported.

In some embodiments, the terminal may report the available time of the GNSS to the base station after acquiring the GNSS measurement results. In some embodiments, the terminal determines that the available time of the GNSS is the validity period of the GNSS reported by the terminal, and the base station does not have additional configuration. However, the GNSS usable time of the terminal may vary based on the operation of the base station, and the terminal may ensure uplink synchronization thereof based on the control of the base station, for example, the control of time-frequency synchronization, in which case the terminal may cause unnecessary power consumption in case of expiration of the GNSS validity period if performing GNSS measurement.
