CONTROL STATION APPARATUS, BASE STATION APPARATUS, RECEIVING METHOD, TRANSMITTING METHOD AND COMMUNICATING METHOD

摘要

A control station apparatus capable of suppressing an increase of the traffic amount and also capable of preventing an increase of overheads during data transfer even when the transmission time interval is shortened. In this apparatus, a data frame processing part (102) makes up a MAC-d PDU from an EDCH FP MDC data frame. A control frame processing part (103), in amacro-diversity communication state, selects, from the EDCH FP MDC control frames of a plurality of Nodes B, frames having the same SN, compares CRC results and estimation bit error rates, and selects a frame in which the CRC result is OK and the estimation bit error rate is small. The control frame processing part (103) then makes up an EDCH FP control response frame in which ACK has been established for Nodes B to which the selected frame can be transmitted, while making up an EDCH FP control response frame in which Flash has been established for the other Nodes B.
