Abstract  Abstract

PROBLEM TO BE SOLVED: To provide techniques for accessing a wireless communication system.

SOLUTION: User equipment (UE) sends a random access preamble including a random identifier (ID) a channel quality indicator (CQI) etc. The UE randomly selects the random ID or this random ID is assigned to the UE. The UE receives a random access response from a base station. The random access response includes control channel resources (CQI and PC resources) uplink resources and control information (timing advance and PC correction) for the UE. The random access response is sent in two parts using two messages. A first message may include identification information and other information on a control channel. A second message may be sent on a shared data channel and may include remaining information for the random access response.
