Detailed Description
The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
Fig. 1 is a schematic flow chart diagram illustrating a method of adjustment indication according to an embodiment of the present disclosure. The adjustment indication method shown in this embodiment may be applied to a first network device, where the first network device may be a network device in a non-terrestrial network, for example, a network device located in the air such as a satellite, an air platform, or a base station located on the ground, and the base station includes, but is not limited to, a base station in various communication systems such as a 4G base station, a 5G base station, and a 6G base station.
The first network device may communicate with a terminal as a user device, including but not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other electronic devices. In one embodiment, the terminal may be a terminal to which the adjustment receiving method described in any of the subsequent embodiments is applied.
As shown in fig. 1, the adjustment indication method may include the steps of:
in step S101, in response to determining that the second network device located in the air switches connection with the ground station, determining transmission delay adjustment association information;
in step S102, the transmission delay adjustment association information is sent to a terminal.
It should be noted that, in this embodiment and other embodiments, it is determined that the second network device located in the air switches the connection with the ground station, which may be that the second network device is switching the connection with the ground station, or that the second network device has already switched the connection with the ground station, or that the second network device is about to switch the connection with the ground station (in a preset time range in the future).
In one embodiment, the second network device located in the air may be a satellite, an air platform, or the like. The ground station may be a base station located on the ground or may be a device for relaying communication signals between the second network device and the base station located on the ground.
For example, the first network device is a base station located on the ground, the first network device may communicate with the terminal through the second network device, and the second network device may transparently transmit communication information between the base station and the terminal. For example, the first network device is identical to the second network device, i.e. the first network device is the second network device, e.g. a satellite, then the first network device may perform the same function as the base station, which belongs to the on-board regeneration mode.
Switching the connection of the second network device to the ground station may result in a change in the communication link between the second network device and the ground station, and in a change in the communication link, a change in the transmission delay of the transmission signal over the communication link may also occur. For example, the communication link becomes shorter, the transmission delay becomes shorter, for example, the communication link becomes longer, and the transmission delay becomes longer.
According to the embodiment of the disclosure, when the second network device switches the connection with the ground station, the first network device may determine transmission delay adjustment association information, and then send the transmission delay adjustment association information to the terminal, for example, may send the transmission delay adjustment association information to the terminal through public (common) signaling or signals, so that the terminal may determine, according to the transmission delay adjustment association information, a transmission delay or an adjusted transmission delay required to be adjusted due to the second network device switching the connection with the ground station, and then adjust a Timing Advance (TA) of communication between the terminal and the first network device according to the required adjusted transmission delay or the adjusted transmission delay, so as to ensure that communication with the first network device based on the adjusted Timing Advance can ensure synchronization of communication.
Optionally, the transmission delay adjustment association information includes at least one of:
the distance of the communication link between the second network device and the ground station is changed, the transmission delay corresponding to the distance is changed, the distance between the second network device and the ground station is changed, and the transmission delay corresponding to the changed distance is changed.
In one embodiment, the transmission delay adjustment association information may be a distance change Δd of a communication link between the second network device and the ground station; the transmission delay adjustment related information may be a transmission delay Δt corresponding to the distance change Δd, for example Δt=Δd/c, and c is a speed of light.
The transmission delay adjustment association information may also be a distance after the communication link between the second network device and the ground station is changed, for example, before the second network device switches the connection with the ground station, the distance between the second network device and the ground station is d1, and then the changed distance is d1- Δd; the transmission delay adjustment related information may be a transmission delay Δt1 corresponding to the changed distance, for example, Δt1= (d1—Δd)/c.
Optionally, the transmission delay adjustment association information is a transmission delay adjustment associated value.
Optionally, the transmission delay adjustment association information is an identifier corresponding to a numerical value associated with the transmission delay adjustment;
the terminal stores an association relation between the identification and the numerical value associated with the transmission delay adjustment in advance.
In one embodiment, the transmission delay adjustment association information may be a transmission delay adjustment associated value, for example, specifically 1ms, 10ms, 20ms, or 1 slot, 10 slots, 20 slots, etc., where the value is not limited to ms and slot, and may be configured as required.
The transmission delay adjustment association information may also be an identifier corresponding to a value associated with the transmission delay adjustment, for example, identifier 1 corresponds to 1ms, identifier 2 corresponds to 10ms, identifier 3 corresponds to 20ms, and an association relationship between the identifier and the value associated with the transmission delay adjustment is prestored in the terminal (for example, the association relationship is sent to the terminal in advance by the first network device), so that the terminal can determine the value associated with the transmission delay adjustment corresponding to the identifier according to the association relationship after receiving the identifier.
Fig. 2 is a schematic flow chart diagram illustrating another adjustment indication method according to an embodiment of the present disclosure. As shown in fig. 2, the method further includes:
in step S103, in response to determining that the second network device switches connection with the ground station, determining a target time at which the second network device switches connection with the ground station;
in step S104, configuration information for receiving the transmission delay adjustment association information is sent to the terminal based on the target time.
In one embodiment, in the case that it is determined that the second network device switches the connection with the ground station, the target time of the second network device switching the connection with the ground station may be further determined, and in particular, the target time may be determined according to the distribution of the operation track of the second network device and the ground station, for example, when the distance between the second network device and the first ground station currently connected is greater than the first distance, and when there is a second ground station having a distance from the second network device smaller than the second distance in the operation direction of the second network device, the time may be determined as the target time, and the second network device is about to switch from the first ground station to the second ground station.
After determining the target time, since the second network device may switch connection with the ground station at the target time, configuration information for receiving the transmission delay adjustment association information may be sent to the terminal based on the target time, for example, time information related to the target time may be carried in the indication configuration information. The time information may be a time, for example, a target time, and the terminal may receive the transmission delay adjustment association information at the time based on the configuration information; the time information may also be a time period, for example, a time period including the target time, for example, a time period starting from the target time, and the terminal may receive the transmission delay adjustment association information based on the duration of the time period from the target time when the configuration information starts.
The configuration information for receiving the transmission delay adjustment association information may include, for example, a period for receiving the delay adjustment association information, a time-frequency resource location for receiving the delay adjustment association information, an aggregation level of the delay adjustment association information, a search space setting, a maximum detection number, and the like.

In one embodiment, in a case of determining that the second network device switches the connection with the ground station, the first rule information of the moment when the second network device switches the connection with the ground station and the second rule information of the transmission delay adjustment association information may be determined according to the running track of the second network device and the distribution information of the ground station.
For example, the first rule information includes a time of day at which each hand-over of the connection with the ground station is made, e.g., 00:12, 01:25, 03:44, 05:15, etc.; the second rule information includes transmission delay adjustment related information corresponding to each handover of the connection of the ground station in one day, for example, 20ms, 17ms, 5ms, 13ms, etc.
For example, the first rule information and the second rule information may form a table, the first rule information is horizontal, the second rule information is vertical, the first rule information and the second rule information are sent to the terminal, specifically, the table may be sent to the terminal, so that the terminal only needs to send the first rule information and the second rule information to the terminal once, and can determine transmission delay adjustment associated information corresponding to each time of switching connection between the second network device and the ground station, and the moment of each time of switching connection between the second network device and the ground station, so that transmission delay adjustment associated information is not required to be transmitted to the terminal for multiple times, and occupation of communication resources is reduced.
