Method and apparatus for handling random access channel responses


Abstract

A method and apparatus for supporting a random access using a random access channel (RACH) are disclosed. The WTRU detects a format of control information in at least one control channel element (CCE) of a common area in a control portion of a downlink transmission. The control information indicates a resource allocation in a data portion of the downlink transmission. The WTRU recovers a random access response assigned to the WTRU from the indicated resource allocation of the data portion on a condition that the at least one CCE has a random access radio network terminal identifier (RA-RNTI) assigned to the WTRU.
