Abstract  Abstract

A method of time-aligning transmissions from multiple base stations to a terminal. To realize time-alignment, the difference between transmission arrival times from base stations, as observed at the terminal, is determined and provided to the system, the timing at the base station such that the terminal-specific radio frame arrives at the terminal within a predetermined time window. It is used to adjust. In one scheme, the time difference between the two base stations is divided into a frame-level time difference and a chip-level time difference. Each time a time difference measurement is performed and reported, the terminal measures the chip-level timing for each candidate base station for the reference base station. In addition, the terminal also measures frame-level timing, and includes this information in time difference measurements only when necessary. Otherwise, the terminal sets the frame-level portion to a predetermined value (eg, zero).
