WIRELESS COMMUNICATION BASE STATION DEVICE, WIRELESS COMMUNICATION TERMINAL DEVICE, AND METHOD FOR SETTING CYCLIC DELAY

摘要

Provided is a base station enabling an increase of the resource utilization efficiency of a precoded dedicated pilot signal. In a base station (100) used in a wireless communication system in which a plurality of pilot blocks with different cyclic delays are allocated to a plurality of units of the UE, respectively, a cyclic shift setting unit (111) sets delay times of the respective pilot blocks so that pilot blocks adjacent to each other in the plurality of the respective pilot blocks overlap with each other, and a channel estimating unit (106) estimates the channel of each unit of the UE by using a CIR that can be obtained from the dedicated pilot signal precoded by the UE and that exists in the pilot block of each unit of the UE.
