The continuous emergence of new Internet applications such as augmented reality (AR), virtual reality (VR) and vehicle-to-vehicle communication has put forward higher requirements for wireless communication technology, driving the continuous evolution of wireless communication technology to meet the needs of applications. Cellular mobile communication technology is in the evolution stage of a new generation of technology. An important feature of the new generation of technology is to support flexible configuration of multiple service types. Since different service types have different requirements for wireless communication technology, for example, the main requirements of the enhanced mobile broadband (eMBB) service type focus on large bandwidth and high rate; the main requirements of the ultra-reliable and low latency communications (URLLC) service type focus on high reliability and low latency; the main requirements of the massive machine type communication (mMTC) service type focus on a large number of connections. Therefore, the new generation of wireless communication systems require flexible and configurable designs to support the transmission of multiple service types.

In the research of wireless communication technology, satellite communication is considered to be an important aspect of the future development of wireless communication technology. Satellite communication refers to the communication conducted by radio communication equipment on the ground using satellites as relays. The satellite communication system consists of a satellite part and a ground part. The characteristics of satellite communication are: large communication range; communication can be carried out between any two points as long as they are within the range covered by the radio waves emitted by the satellite; not easily affected by land disasters (high reliability). As a supplement to the current ground cellular communication system, satellite communication can have the following benefits: Extended coverage: For areas that cannot be covered by the current cellular communication system or have high coverage costs, such as oceans, deserts, remote mountainous areas, etc., satellite communication can be used to solve communication problems. Emergency communication: In extreme cases such as disasters such as earthquakes that make the cellular communication infrastructure unavailable, satellite communication can be used to quickly establish a communication connection. Provide industry applications: For example, for delay-sensitive services for long-distance transmission, satellite communication can be used to reduce the delay of service transmission. It can be foreseen that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration and truly realize the intelligent connection of all things.

In some embodiments, in the scenario of satellite communication, due to the long signal transmission distance between the transmitter and the receiver, data transmission takes a long time. For transmissions with uplink and downlink relationships, it is determined that the terminal needs to compensate for the propagation delay based on the configuration of the base station. Compensation for propagation delay can be applied to a variety of operations, such as physical uplink shared channel (PUSCH) transmission scheduled by downlink control information (DCI); transmission of hybrid automatic repeat request (HARQ) feedback information and transmission of media access control control element (MAC CE). Please refer to Figure 1b for the scenario of uplink and downlink timing alignment on the base station side; please refer to Figure 1c for the scenario of uplink and downlink timing misalignment on the base station side.

In some embodiments, the terminal needs to obtain location information to determine the timing compensation information of the uplink transmission. The terminal can determine its own location information through the GNSS measurement module. For IoT terminals, it may not support the simultaneous operation of the cell (cellular) module and the GNSS module, and may only support sporadic (intermittent) transmission.

In some embodiments, after the terminal obtains the GNSS measurement results, the GNSS available time can be reported to the base station through the GNSS validity period. In some embodiments, the terminal determines that the GNSS available time is the GNSS validity period reported by it, and the base station does not make additional configurations. However, the GNSS available time of the terminal may change based on the operation of the base station. The terminal can ensure its uplink synchronization based on the control of the base station, for example, the control of time and frequency synchronization. In this case, if the terminal performs GNSS measurement when the GNSS validity period expires, It will cause unnecessary power consumption.

In some embodiments, the above method may include the method described in the above-mentioned embodiments of the indication information system side, terminal side, network device side, etc., which will not be repeated here.

The present disclosure relates to an information indication method, which includes:

In some embodiments, the terminal reports information related to the GNSS validity duration, and the information related to the GNSS validity duration includes at least one of the following information: the starting position of the current GNSS validity duration; the complete time of the current GNSS validity duration; the remaining available time of the current GNSS validity duration. The end time position of the current GNSS validity duration. Here, the GNSS validity duration corresponds to the valid time in the present disclosure.

In some embodiments, the terminal determines the GNSS validity duration based on the second information of the base station.

In some embodiments, the terminal receives high-layer signaling such as RRC signaling, MAC CE or physical layer signaling such as DCI sent by the base station to determine the second information of GNSS validity duration.

In some embodiments, the second information is used by the terminal to determine the available time period of the GNSS information.

In some embodiments, the length of the GNSS validity duration indicated in the second information is greater than or equal to the length of the GNSS validity duration reported by the terminal.

In some embodiments, the second information may include: the starting position and length information of the GNSS validity duration; the starting position and ending position information of the GNSS validity duration;

In some embodiments, it is determined that the GNSS validity duration configured by the base station is greater than the GNSS validity duration most recently reported by the terminal, and the terminal determines that it supports adjusting its uplink synchronization based on the base station's time and frequency adjustment command.

In some embodiments, the terminal receives a time-frequency adjustment command sent by the base station to determine its uplink time-frequency synchronization information. The time-frequency adjustment command can be sent via high-layer signaling such as RRC signaling or MAC CE, or via physical layer signaling such as DCI.

In some embodiments, the terminal determines the starting position of detecting the time-frequency adjustment command, including:

Method 1: Start monitoring after the GNSS validity duration expires;

In this way, after the terminal determines that the available time end position of the GNSS validity duration configured by the base station is at the end position determined in the reported information, the terminal starts receiving target instructions from the end position of the GNSS validity duration determined in the reported information, and the target instructions carry indication information related to the time and frequency adjustment command.

Alternatively, in another implementation method, the terminal may start receiving a target instruction after a predefined time, such as X subframes, after the end position of the GNSS validity duration determined from the reported information, wherein the target instruction carries indication information related to the time-frequency adjustment command. The X is predefined or determined by receiving the second information from the base station.

Method 2: Start monitoring after receiving the second GNSS validity duration message;

In this method, after receiving the second GNSS validity duration information, the terminal starts to receive the target instruction with or without delaying a predefined or preconfigured time, and the target instruction carries indication information related to the time and frequency adjustment command.

Method 3: Always monitor

Under this method, regardless of whether the GNSS validity duration configured by the base station is greater than the GNSS validity duration most recently reported by the terminal, the terminal always receives the target instruction, which carries indication information related to the time and frequency adjustment command.

In some embodiments, the terminal autonomously determines the GNSS validity duration

When the terminal does not receive the second information indicating the GNSS validity duration from the base station, the terminal determines that the GNSS validity duration is the GNSS validity duration reported by the terminal most recently. When the terminal determines that the GNSS validity duration has expired, it receives a time domain or frequency domain adjustment command sent by the base station in a predefined time window. The starting position of the predefined time window is the time position when the GNSS validity duration expires, and the length is configurable.
