INTEGRATED CIRCUIT FOR CONTROLLING A PROCESS

摘要

Provided is a cyclic shift sequence generation method which can prevent coming of an interference wave into a desired wave detection window even if a cyclic shift sequence has a high mutual correlation in different bandwidths, thereby improving a channel estimation accuracy in a base station. In this method, a cyclic shift sequence number to be allocated to a cell is decided in advance. Moreover, when the cyclic shift amount between cyclic shift sequences allocated in cells is Δ1 and the cyclic shift amount of the cyclic shift sequences allocated between the cells is Δ2, Δ1 and Δ2 are made different when generating a cyclic shift sequence.

1. An integrated circuit for controlling a process comprising:
receiving control information transmitted from a base station; generating a reference signal based on a cyclic shift number out of a plurality of cyclic shift numbers, the cyclic shift number being given by the control information; and transmitting the reference signal, wherein the plurality of cyclic shift numbers includes two cyclic shift numbers, which are next to each other in order of cyclic shift number and a difference between which is a first interval, and two cyclic shift numbers, which are next to each other in order of cyclic shift number and a difference between which is a second interval different from the first interval.
