Method for generating a carrier group and method for transmitting carrier group information

摘要

Disclosed are: a variety of methods and apparatuses for aggregating a plurality of carriers and using the carrier aggregation in a wireless connection system; and a variety of methods and apparatuses for providing information on the structure of a carrier generated by aggregating a plurality of carriers. A method for transmitting and receiving carrier group information, according to one embodiment of the present invention, includes the steps of: a mobile terminal transmitting a first message containing multi-carrier performance information of the mobile terminal to a base station; and the mobile terminal receiving, from the base station, a second message containing allocation information on the wireless resource allocated on the basis of the multi-carrier information. Here, multi-carrier performance information includes a spectral mask-type parameter for the supportable multi-carrier of the mobile terminal.

主权项

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.
