Abstract  Abstract

METHOD AND EQUIPMENT FOR ALIGNING TIME TRANSMISSIONS OF SEVERAL STATIONS BASED ON CDMA COMMUNICATION SYSTEM These are schemes for time-aligning transmissions from multiple base stations to one terminal. To achieve time alignment, differences in arrival times of base station transmissions observed at the terminal are determined and provided to the system and employed to adjust synchronization at the base stations so that terminal-specific radios reach the terminal. within a specific time window. In a scheme, a time difference between two base stations is partitioned into a frame level time difference and a chip level difference. When asked to make and report time difference measurements, the terminal measures chip-level synchronization for each candidate base station against a reference base station. In addition, the terminal also measures frame-level synchronization and includes this information in time difference measurement only if necessary. Otherwise, the terminal sets the frame level portion to a predetermined value (such as zero).
