Abstract  Abstract

A method and apparatus for supporting random access using a RACH (Random Access Channel) is disclosed. Each of a plurality of WTRUs (wireless transmission / reception units) sends a random access request to the base station on the uplink RACH preamble. A RACH Response (AICH (Access Indication Channel) message) sent by the base station is received by each WTRU. The received RACH response signal includes a control part (PDCCH (physical downlink control channel)) and a data part (PDSCH (physical downlink shared channel). The control signal part of RACH Response is the position of the RACH Response message part. The RACH Response control signal comprises a plurality of CCEs (Control Channel Elements) and allocates each CCE to provide each WTRU with its unique RACH Response control signal, which was sent by the base station. It is configured to identify its intended CCE among multiple CCEs, blind decoding.
