TIMING ADVANCE ENHANCEMENTS FOR CELLULAR COMMUNICATIONS

摘要

Described are modifications to the operating behavior of a mobile station in a cellular communications network that reduce the extent procedures for updating a timing advance value used to compensate for propagation delays in transmitting to a base station. The mobile station is configured to operate in either a moving mode or a stationary mode, where usual timing advance updating procedures are followed in the moving mode and modified in the stationary mode.
