Abstract  Abstract

PROBLEM TO BE SOLVED: To provide techniques of efficiently performing signal acquisition in a wireless communication system.

SOLUTION: Each base station transmits a TDM pilot 1 generated with a PN1 sequence and a TDM pilot 2 generated with a PN2 sequence. Each base station is assigned a specific PN2 sequence that uniquely identifies that base station. A terminal uses the TDM pilot 1 to detect the presence of a signal and uses the TDM pilot 2 to identify base stations and obtain accurate timing. For signal detection the terminal performs delayed correlation on received samples and determines whether a signal is present. If a signal is detected the terminal performs direct correlation on the received samples with the PN1 sequences for K1 different time offsets and identifies K2 strongest TDM pilot 1 instances. For time synchronization the terminal performs direct correlation on the received samples with the PN2 sequences to detect the TDM pilot 2.
