Method for generating a reference signal sequence using grouping

摘要

Method for generating reference signal sequence using grouping is explained. In this method, base sequences are grouped such that each group contains at least one base sequence of each length, so UE(s) can use various length sequences as a reference signal. And in this method, inter cell interference caused by using various length sequence as a reference signal sequence can be minimized by grouping sequences having the high cross correlation relation.

1. A method for transmitting a reference signal sequence at a transmitting party in a multi-cell environment, the method comprising:
acquiring the reference signal sequence using one or more sequences having a length corresponding to one or multiple of a resource block size, wherein the resource block size corresponds to 12 subcarriers, wherein the one or more sequences are acquired by cyclic extension of a Zadoff-Chu sequence having a largest prime number length that is less than the length corresponding to one or multiple of the resource block size; and transmitting the reference signal sequence to a receiving party, wherein the one or more sequences are acquired from among a plurality of sequences divided into sequence groups determined based on an index of each of the one or more sequences and the largest prime number length of the Zadoff-Chu sequence.
