Abstract:
1. A method for negotiating multicarrier capability in a wireless access system supporting a carrier aggregation scheme, the method comprising: transmitting, by a mobile station (MS), a registration request (REG-REQ) message to a base station (BS) to negotiate the multicarrier capability and register to the BS during a network entry procedure, the REG-REQ message including information about multicarrier capabilities supportable by the MS; receiving, by the MS, a registration response (REG-RSP) message from the BS in response to the REG-REQ message, the REG-RSP message including information about multicarrier capabilities supportable by the BS; and receiving, by the MS, a message comprising a multicarrier configuration index (MCI) which represents a multicarrier configuration and a frequency shift value from the BS, wherein the multicarrier configuration indicates bandwidth information for one or more available carriers, and wherein the message comprising the MCI is received through a primary carrier among the one or more available carriers.
