METHOD AND APPARATUS FOR GENERATING CODE SEQUENCE IN A COMMUNICATION SYSTEM

摘要

A method for transmitting a synchronization signal by a transmitting side device to a receiving side device in a wireless access system. The method includes generating a concatenated code sequence in a frequency domain by concatenating a first code sequence having a first index (M1) and a second code sequence having a second index (M2). Each of the first code sequence and the second code sequence is obtained by cyclic shifting a code sequence. The concatenated code sequence is mapped to subcarriers for transmitting the synchronization signal via a secondary synchronization channel (S-SCH). The method further includes transforming the concatenated code sequence into a time domain signal; and transmitting the time domain signal to the receiving side device as the synchronization signal. The concatenated code sequence indicates a cell group identity (ID).

1. A method for transmitting a synchronization signal by a transmitting side device to a receiving side device in a wireless access system, the method comprising:
generating a concatenated code sequence in a frequency domain by concatenating a first code sequence having a first index (M1) and a second code sequence having a second index (M2), wherein each of the first code sequence and the second code sequence is obtained by cyclic shifting a code sequence, and wherein the concatenated code sequence is mapped to subcarriers for transmitting the synchronization signal via a secondary synchronization channel (S-SCH); transforming the concatenated code sequence into a time domain signal; and transmitting the time domain signal to the receiving side device as the synchronization signal, wherein the concatenated code sequence indicates a cell group identity (ID).
