METHOD AND APPARATUS FOR TRANSCEIVING DATA VIA A CONTENTION-BASED PHYSICAL UPLINK DATA CHANNEL

摘要

Disclosed are a method and apparatus for transceiving data via a contention-based physical uplink data channel. A terminal apparatus, which transmits data via a contention-based physical uplink data channel, comprises: a transmitter which transmits data via a contention-based physical uplink data channel and scheduling request information via a scheduling request channel simultaneously or consecutively to a base station; a receiver which receives a physical hybrid-ARQ indicator channel (PHICH) or an uplink (UL) grant message from the base station; and a processor which decodes the physical hybrid-ARQ indicator channel (PHICH) or the uplink (UL) grant message to determine whether an ACK signal or a NACK signal is indicated. Here, the scheduling request channel can be a specific channel allocated to the terminal apparatus so as to discriminate the terminal from other terminal apparatuses.
