Abstract
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.
Claims8
A method for a base station to receive a reference signal from a user equipment in a wireless communication system, the method comprising:
- receiving the reference signal from the user equipment;
- and
- processing the received reference signal,
- wherein the reference signal is defined based on a Zadoff Chu sequence having a length ‘NzcRS’ and a root index ‘q’, the root index ‘q’ determined based on a group index ‘u’, the length ‘NzcRS’, and a sequence index ‘v’ for each length ‘NzcRS’ within a sequence group corresponding to the group index ‘u’, and the group index ‘u’ corresponding to a cell where the user equipment is operating.
A base station for receiving a reference signal from a user equipment in a wireless communication system, the base station comprising:
- a RF unit for receiving the reference signal from the user equipment;
- and
- a processor for processing the reference signal based on that:
- the reference signal is defined based on a Zadoff Chu sequence having a length ‘NzcRS’ and a root index ‘q’, the root index ‘q’ determined based on a group index ‘u’, the length ‘NzcRS’, and a sequence index ‘v’ for each length ‘NzcRS’ within a sequence group corresponding to the group index ‘u’, the group index ‘u’ corresponding to a cell where the user equipment is operating.
