Abstract
Disclosed are a method for physical uplink control channel transmission/reception between a terminal and a base station in a wireless communication system, and an apparatus supporting the same. More particularly, a method for physical uplink control channel (PUCCH) transmission/reception between a terminal and a base station, disclosed herein, can reduce a peak-to-average power ratio (PAPR).
Claims8
A method of transmitting a physical uplink control channel (PUCCH) to a base station (BS) by a user equipment (UE) in a wireless communication system, the method comprising:
- configuring the PUCCH by repeating N times a resource group in which N numbers of data are frequency division multiplexed (FDMed) in a direction of a frequency domain with respect to each of at least one symbol, where N is an integer greater than 2;
- and
- transmitting the configured PUCCH in the at least one symbol by applying phase rotations with different angles to the N numbers of data, respectively,
- wherein the N numbers of data includes one demodulation reference signal (DM-RS) and N−1 number of uplink control information, the N−1 is an integer greater than 1,
- wherein the one DM-RS is allocated to one interlace among N interlaces, and the uplink control information is allocated to N−1 interlaces among the N interlaces, the N−1 interlaces being different than the one interlace of the one DM-RS, and
- wherein the one DM-RS is transmitted in the one interlace with no phase rotation, and the N−1 number of uplink control information are transmitted in corresponding ones of the N−1 interlaces with corresponding different non-zero phase rotation angles.
A method of receiving a physical uplink control channel (PUCCH) from a user equipment (UE) by a base station (BS) in a wireless communication system, the method comprising:
- receiving the PUCCH via at least one symbol,
- wherein the PUCCH is configured by repeating N times a resource group in which N numbers of data are frequency division multiplexed (FDMed) in a direction of a frequency domain with respect to the each of the at least one symbol, where N is an integer greater than 2;
- and
- decoding the N numbers of data received in the at least one symbol by applying phase rotations with different angles to the N numbers of data, respectively,
- wherein the N numbers of data includes one demodulation reference signal (DM-RS) and N−1 number of uplink control information, the N−1 is an integer greater than 1,
- wherein the one DM-RS is allocated to one interlace among N interlaces, and the uplink control information is allocated to N−1 interlaces among the N interlaces, the N−1 interlaces being different than the one interlace of the one DM-RS, and
- wherein the one DM-RS is transmitted in the one interlace with no phase rotation, and the N−1 number of uplink control information are transmitted in corresponding ones of the N−1 interlaces with corresponding different non-zero phase rotation angles.
A user equipment (UE) for transmitting a physical uplink control channel (PUCCH) to a base station (BS) in a wireless communication system, the UE comprising:
- a transmitter;
- and
- a processor connected to the transmitter,
- wherein the processor is configured to:
- configure the PUCCH by repeating N times a resource group in which N numbers of data are frequency division multiplexed (FDMed) in a direction of a frequency domain with respect to each of at least one symbol, where N is an integer greater than 2;
- and
- transmit the configured PUCCH in the at least one symbol by applying phase rotations with different angles to the N numbers of data, respectively,
- wherein the N numbers of data includes one demodulation reference signal (DM-RS) and N−1 number of uplink control information, the N−1 is an integer greater than 1,
- wherein the one DM-RS is allocated to one interlace among N interlaces, and the uplink control information is allocated to N−1 interlaces among the N interlaces, the N−1 interlaces being different than the one interlace of the one DM-RS, and
- wherein the one DM-RS is transmitted in the one interlace with no phase rotation, and the N−1 number of uplink control information are transmitted in corresponding ones of the N−1 interlaces with corresponding different non-zero phase rotation angles.
