METHOD AND APPARATUS FOR CREATING COMMON PHYSICAL CHANNEL

摘要

A method and an apparatus for creating common channels in an uplink are provided to improve the receive ability of mobile stations by efficiently allocating resources in the case of creating common channels in a downlink. An apparatus for creating common channels for an uplink in a base station having a plurality of antennas comprises a common channel generation part(100), an antenna mapping part(400), a multiplexing part(500), and a scrambling part(600). The common channel generation part generates common channel signals to create a common channel to transmit common data which will be provided to a plurality of mobile stations through the downlink. The antenna mapping part maps the generated common channel signals to the antennas respectively. The multiplexing part receives the mapped common channel signals according to the antennas, sequentially allocates them to subcarriers and time resources, and outputs a single symbol. Using a scramble sequence, the scrambling part scrambles the outputted symbol.
