User equipment parameter determination method and apparatus, and storage medium and base station

A User Equipment (UE) parameter determination method, comprising:

• determining, by a base station, a minimum round trip time between each UE in a cell and a satellite, wherein the minimum round trip time is a timing difference by which a network-side uplink radio frame lags behind a network-side downlink radio frame;
• determining, by the base station, frame information of the network-side uplink radio frame based on the minimum round trip time and frame information of the network-side downlink radio frame;
• and
• determining, by the base station, a UE parameter of each UE based on the network-side uplink radio frame and the network-side downlink radio frame, where the UE parameter comprises at least one of Timing Advance (TA) or K2, wherein K2 is a time period from a slot where an uplink resource carrying Uplink (UL) grant indication information is located to a slot where a resource of a UL grant is located;
• wherein the UE parameter comprises TA, and said determining, by the base station, the UE parameter of each UE based on the network-side uplink radio frame and the network-side downlink radio frame comprises:
• determining the TA by deducting the minimum round trip time from a round trip time, wherein the round trip time is determined based on a random access preamble received when the UE performs random access.
