Method and Apparatus for Layer 2 Compression Signaling

An apparatus for use in a user equipment to set up a L2 compression-decompression operation, the apparatus comprising a processing system, wherein the processing system comprises a processor and at least one memory storing at least one computer program wherein the memory storing the at least one computer program is configured with the processor to cause the apparatus to:

• signal a set of L2 compression-decompression capabilities to a serving radio network controller (RNC) or a serving base station on a uplink control channel, wherein the set of L2 compression-decompression capabilities are included in a capability information element (IE) of a RRC message;
• receive a set of L2 compression-decompression control parameters in a signaling message on a downlink control channel from the serving RNC or the serving base station;
• and
• configure a local set of L2 compression-decompression control parameters based on the received set of L2 compression-decompression control parameters.
