Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and an apparatus for supporting random access using a random access channel (RACH).

SOLUTION: Each of a plurality of wireless transmit/receive units (WTRUs) sends a random access request to a base station on an uplink RACH preamble. An RACH response signal (access indication channel (RAICH) message) sent by the base station is received by each WTRU. The received RACH response signal comprises a control portion (physical downlink control channel (PDCCH)) and a data portion (physical downlink shared channel (PDSCH)). The RACH response signal includes a plurality of control channel elements (CCEs). Each WTRU is allocated with respective CCEs to provide the unique RACH response control signal. The WTRU is configured to identify the intended CCE from among the plurality of CCEs sent by the base station.
