Method and Apparatus for Communicating Protocol Data Unit in Radio Access Network
First Claim
1. A method, comprising:
- indicating identity of a first network component in a radio access network in out-of-band signaling, the first network component configured for communicating a protocol data unit to a second network component over a logical channel in the radio access network; and
identifying the logical channel and routing of the logical channel in the protocol data unit.

Abstract
A new protocol data unit is used in communications in a radio access network. When a user equipment requests a radio resource controller connection, the UE includes its identity in the request message. In establishing the connection to UE, a serving radio network controller allocates a logical channel to the UE for communications and identifies the logical channel in the header of the protocol data unit so as to allow a receiver of the PDU to know the UE identity in an out-of-band signaling fashion, depending upon a state of the transmitter of the PDU. When the transmitter changes its state, the receiver can change state accordingly. The new PDU structure allows continuous reception of the HS-DSCH downlink channel during state transition form CELL_FACH or CELL_PCH or URA_PCH to CELL_DCH and vice versa. This new PDU structure also allows continuous HS_DSCH retransmissions.
