Abstract
A method for transmitting a reference signal by a user equipment (UE) in a wireless communication system. The UE generates an uplink reference signal in a subframe comprising first, second, third, fourth, fifth, sixth and seventh orthogonal frequency division multiplexing (OFDM) symbols in time domain and a plurality of subcarriers in frequency domain. The UE transmits the uplink reference signal to a base station in the third, fourth and fifth OFDM symbols. The transmitted uplink reference signal is hopped in the frequency domain, based on a cell specific hopping parameter.

A method for transmitting a reference signal by a user equipment (UE) in a wireless communication system, the method comprising:
- generating, by the UE, an uplink reference signal in a subframe comprising first, second, third, fourth, fifth, sixth and seventh orthogonal frequency division multiplexing (OFDM) symbols in time domain and a plurality of subcarriers in frequency domain;
- transmitting, by the UE to a base station, the uplink reference signal in the third, fourth and fifth OFDM symbols,
- wherein the transmitted uplink reference signal is hopped in the frequency domain, based on a cell specific hopping parameter;
- and
- transmitting, by the UE to the base station, uplink control information including a hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal in the first, second, sixth and seventh OFDM symbols on an uplink control channel.
A device configured to transmit a reference signal in a wireless communication system, the device comprising:
- a processing unit configured to generate an uplink reference signal in a subframe comprising first, second, third, fourth, fifth, sixth and seventh orthogonal frequency division multiplexing (OFDM) symbols in time domain and a plurality of subcarriers in frequency domain;
- and
- a transmitting unit configured to transmit, to a base station, the uplink reference signal in the third, fourth and fifth OFDM symbols,
- wherein the transmitted uplink reference signal is hopped in the frequency domain, based on a cell specific hopping parameter, and
- wherein the transmitting unit is further configured to transmit, to the base station, uplink control information including a hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal in the first, second, sixth and seventh OFDM symbols on an uplink control channel.
