Method and apparatus for transmitting and receiving signals in wireless communication system

摘要

An apparatus and a method for allocating resources for transmitting an HARQ ACK/NACK signal for a downlink subframe using a PUCCH format 3 in a time division duplex (TDD) system using a single carrier are provided. Since the resources are allocated through a resource indicator transmitted using a power control field transmitted on a PDCCH of the downlink subframe, the resources for transmitting the HARQ ACK/NACK signal may be allocated by effectively using resources allocated to a duplicately transferred control signal.

1. A method for transmitting control information of a base station in a time division duplex (TDD) system, the method comprising:
configuring a first transmit power control (TPC) command for controlling a physical uplink control channel (PUCCH) transmission power and a second TPC command which indicates resources for the PUCCH in an uplink (UL) subframe; and performing a transmission of a first physical downlink control channel (PDCCH) including the first TPC command in a first downlink (DL) subframe and a transmission of a second PDCCH including the second TPC command in a second DL subframe, wherein the first and the second DL subframes correspond to the UL subframe; and performing a transmission of physical downlink shared channels (PDSCHs) in the first and the second DL subframes, wherein the transmission of the PDSCHs in the first and the second DL subframes and a reception of the PUCCH in the UL subframe are performed on a single carrier.
