TRANSMISSION DIVERSITY SCHEME ON PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) WITH ACK/NACK DIFFERENTIATION |
摘要 |
A method for transmitting uplink control information (UCI) using a physical uplink control channel (PUCCH) transmit diversity scheme is described. A UCI is coded with a Reed-Muller code to obtain a coded UCI. The coded UCI is mapped to quadrature phase shift keying (QPSK) symbols to obtain a mapped coded UCI. A phase shift is applied to the mapped coded UCI based on an acknowledge/negative-acknowledge (ACK/NACK) to obtain a phase shifted mapped coded UCI. The mapped coded UCI is sent using a PUCCH resource on a first antenna. The phase shifted mapped coded UCI is sent using a PUCCH resource on a second antenna.
