Assignee: DATANG MOBILE COMMUNICATIONS EQUIPMENT CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The method according to claim 1, wherein the common transmission delay comprises at least one of the following information:
a reference round trip time (RTT) of data transmission between the terminal in the at least one cell and the network device;
a maximum RTT of data transmission between the terminal in the at least one cell and the network device;
a difference value between a maximum RTT and a reference RTT of data transmission between the terminal in the at least one cell and the network device;
a transmission delay of a feeder link in a satellite communication system, wherein the feeder link is a link between a gateway station and a satellite;
a reference transmission delay of a service link in a satellite communication system, wherein the service link is a link between a satellite and a terminal;
a maximum transmission delay of a service link in the satellite communication system;
a difference value between a maximum transmission delay and a reference transmission delay of a service link in a satellite communication system;
a transmission delay of a satellite or a gateway station and a common reference point of the at least one cell;
a difference value between transmission delays of a satellite or a gateway station and common reference points of a plurality of different cells;
a TA determined based on a transmission delay of a satellite or a gateway station and a common reference point of the at least one cell; or
a difference value between TAs of different cells.
