Abstract
Provided are: a method by which a terminal and a base station transmit/receive a signal in a wireless communication system; and a communication device using the method. The method allocates, to a plurality of antenna ports, resources for transmitting a physical uplink control channel (PUCCH) composed of two or less symbols, and transmits, to the base station, the PUCCH through the plurality of antenna ports, wherein the resources allocated to the plurality of antenna ports are multiplexed with each other.
Claims8
A method of transmitting a signal by a User Equipment (UE) to a Base Station (BS) in a wireless communication system, the method comprising:
- allocating 2 symbols for a Physical Uplink Control Channel (PUCCH) to a plurality of antenna ports;
- and
- transmitting, to the BS, the PUCCH through the plurality of antenna ports,
- wherein resources included in the 2 symbols are multiplexed,
- wherein, based on that a frequency hopping is applied, a Spatial Orthogonal Resource Transmit Diversity (SORTD) scheme is applied as the transmit diversity scheme for the 2 symbols, and
- wherein, based on that (i) the frequency hopping is not applied and (ii) a reference signal (RS) for the PUCCH and Uplink Control Information (UCI) for the PUCCH are interlaced in a symbol, a Space Time Block Coding (STBC) scheme is applied as the transmit diversity scheme for the 2 symbols.
A method of receiving a signal by a Base Station (BS) from a User Equipment (UE) in a wireless communication system, the method comprising:
- allocating 2 symbols for a Physical Uplink Control Channel (PUCCH) to the UE;
- and
- receiving the PUCCH through a plurality of antenna ports of the UE based on the the 2 symbols,
- wherein resources included in the 2 symbols are multiplexed,
- wherein, based on that a frequency hopping is applied, a Spatial Orthogonal Resource Transmit Diversity (SORTD) scheme is applied as the transmit diversity scheme for the 2 symbols, and
- wherein, based on that (i) the frequency hopping is not applied and (ii) a reference signal (RS) for the PUCCH and Uplink Control Information (UCI) for the PUCCH are interlaced in a symbol, a Space Time Block Coding (STBC) scheme is applied as the transmit diversity scheme for the 2 symbols.
A User Equipment (UE) for transmitting a signal to a Base Station (BS) in a wireless communication system, the UE comprising:
- a transceiver;
- and
- a processor,
- wherein the processor is configured to:
- allocate 2 symbols for a Physical Uplink Control Channel (PUCCH) to a plurality of antenna ports;
- and
- control the transceiver to transmit, to the BS, the PUCCH through the plurality of antenna ports, and
- wherein resources included in the 2 symbols are multiplexed,
- wherein, based on that a frequency hopping is applied, a Spatial Orthogonal Resource Transmit Diversity (SORTD) scheme is applied as the transmit diversity scheme for the 2 symbols, and
- wherein, based on that (i) the frequency hopping is not applied and (ii) a reference signal (RS) for the PUCCH and Uplink Control Information (UCI) for the PUCCH are interlaced in a symbol, a Space Time Block Coding (STBC) scheme is applied as the transmit diversity scheme for the 2 symbols.
A Base Station (BS) for receiving a signal from a User Equipment (UE) in a wireless communication system, the BS comprising:
- a transceiver;
- and
- a processor,
- wherein the processor is configured to:
- allocate 2 symbols for a Physical Uplink Control Channel (PUCCH) to the UE and
- control the transceiver to receive the PUCCH through a plurality of antenna ports of the UE based on the 2 symbols,
- wherein resources included in the 2 symbols are multiplexed,
- wherein, based on that a frequency hopping is applied, a Spatial Orthogonal Resource Transmit Diversity (SORTD) scheme is applied as the transmit diversity scheme for the 2 symbols, and
- wherein, based on that (i) the frequency hopping is not applied and (ii) a reference signal (RS) for the PUCCH and Uplink Control Information (UCI) for the PUCCH are interlaced in a symbol, a Space Time Block Coding (STBC) scheme is applied as the transmit diversity scheme for the 2 symbols.
