<p>A method for a user equipment (UE) to set up a layer 2 (L2) compression-decompression operation, comprises signalling a set of L2 compression-decompression capabilities to a serving radio network controller (RNC) or a serving base station on a uplink control channel the set of L2 compression-decompression capabilities included in a capability information element (IE) of a RRC message; receiving a set of L2 compression-decompression control parameters in a signalling message on a downlink control channel from the serving RNC or the serving base station; and configuring a local set of L2 compression-decompression control parameters based on the received set of L2 compression-decompression control parameters. There may be a compression-decompression flag indicated in the received compression-decompression parameters. The L2 compression-decompression capability information may comprise a compression direction, a precompression data amount, one or more data types supported and a compression algorithm. Multiple methods are disclosed.</p> |
