METHOD AND APPARATUS FOR TRANSFER OF A MESSAGE ON A COMMON CONTROL CHANNEL FOR RANDOM ACCESS IN A WIRELESS COMMUNICATION NETWORK
First Claim
1. A method for wireless communication, comprising:
- sending a message on a control channel for random access by a user equipment (UE);
sending a reserved channel identifier to indicate the message being sent on the control channel; and
sending the message and the reserved channel identifier on an uplink shared channel carrying the control channel.

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.

13. A method for wireless communication, comprising:
-
generating a short message authentication code for integrity protection (MAC-I) for a message sent on a control channel for random access by a user equipment (UE), the short MAC-I having a smaller size than a full MAC-I used for integrity protection of messages sent on a control plane; and sending the message comprising the short MAC-I for random access by the UE. - View Dependent Claims (14, 15, 16)

17. A method for wireless communication, comprising:
-
setting a format field of a message to a first value to indicate a first type of user equipment (UE) identity (ID) being sent in the message or to a second value to indicate a second type of UE ID being sent in the message; generating the message comprising the format field and a UE ID of the type indicated by the format field; and sending the message for random access by a UE. - View Dependent Claims (18, 19, 20, 21, 22)

23. A method for wireless communication, comprising:
-
generating a Radio Resource Control (RRC) message on a common control channel (CCCH) for random access by a user equipment (UE); generating a Medium Access Control (MAC) service data unit (SDU) comprising the RRC message; generating a MAC sub-header comprising a reserved logical channel identifier (LCID) to indicate the RRC message being sent on the CCCH; generating a MAC protocol data unit (PDU) comprising the MAC sub-header and the MAC SDU; and sending the MAC PDU for random access by the UE. - View Dependent Claims (24, 25, 26)
