Abstract
Techniques for sending a message for random access by a user equipment (UE) are described. In an aspect, the UE may send the message on a control channel for random access and may send a reserved channel identifier to indicate the message being sent on the control channel. In another aspect, the UE may send the message in a protocol data unit (PDU) and may send additional information (e.g., a buffer status report) in the PDU if it can accommodate the additional information. In yet another aspect, the UE may generate a short message authentication code for integrity protection (MAC-I) for the message. The short MAC-I may have a smaller size and may be used to authenticate the UE. In yet another aspect, the UE may send a UE ID of one of multiple types for random access and may convey the UE ID type via a format field in the message.
