Claim of US Patent No. 11,032,805

1. A method for receiving control information by a user equipment (UE) in a wireless communication system, the method comprising:receiving a physical downlink control channel (PDCCH) signal including an uplink scheduling information;
transmitting a physical uplink shared channel (PUSCH) signal and a reference signal (RS) for the PUSCH signal using the uplink scheduling information including a cyclic shift field indicating a cyclic shift value of the RS for the PUSCH signal on one or more resource block including a plurality of symbols; and
receiving a physical hybrid ARQ indicator channel (PHICH) including an acknowledgement information for the PUSCH signal,
wherein the RS for the PUSCH signal is transmitted on even-numbered subcarriers or odd-numbered subcarriers in a specific symbol of the plurality of symbols,
wherein whether the RS for the PUSCH signal is transmitted on the even-numbered subcarriers or the odd-numbered subcarriers in the specific symbol of the plurality of the symbols is implicitly indicated based on the cyclic shift value,
wherein a PHICH resource index determined when the RS for the PUSCH signal is transmitted on the odd-numbered subcarriers is different from a PHICH resource index determined when the RS for the PUSCH signal is transmitted on the even-numbered subcarriers by a offset value.
