Abstract  Abstract

Techniques are described for accessing a wireless communication system. A user equipment (EU) sends a random access preamble for system access. The random access preamble may include a random identifier (ID) a channel quality indicator (CQI) etc. The eu can randomly select the random id or may be assigned this random id. THE EU receives a random access response from a base station. The random access response may include control channel resources (e.g. CQI and PC resources) uplink resources and/or control information (e.g. timing advance and pc correction) for the eu. The random access response may be sent in two parts using two messages. A first message may be sent on a control channel and may include identification information and possibly other information. A second message may be sent on a shared data channel and may include remaining information for the random access response.
