Method for transceiving data in a wireless access system, and base station and terminal for same

摘要

Disclosed are a method for transceiving data in a wireless access system, and a base station and terminal therefor. More particularly, the present invention relates to a method for transceiving data, and to a base station device for the method, wherein the method comprises the steps of: transmitting, in a single first subframe, a physical downlink control channel (PDCCH) including downlink scheduling information on each terminal; and transmitting, in a plurality of second subframes, a physical downlink shared channel (PDSCH) relevant to said PDCCH to each terminal. The PDCCH supports a carrier aggregation that includes a field indicating said plurality of second subframes in which said PDSCH is transmitted.

1. A method for transmitting data at a base station (BS) in a wireless access system, the method comprising:
transmitting, to a user equipment (UE), a Radio Resource Control (RRC) signal indicating whether each one of a plurality of carrier indication field (CIF) values belongs to a first group or a second group; transmitting, to the UE, a physical downlink control channel (PDCCH) including a CIF value in a first subframe via a first carrier, wherein the CIF value is one of the plurality of CIF values in the first group or the second group; and transmitting a physical downlink shared channel (PDSCH) corresponding to the PDCCH to the UE according to the CIF value in the PDCCH, wherein a CIF value in the first group indicated an index of a carrier on which data is to be transmitted, and a CIF value in the second group indicates an index of a subframe in which date is to be transmitted, and wherein when the CIF value in the PDCCH belongs to the first group, data is transmitted only in the first subframe via a carrier indicated by the CIF value, and when the CIF value in the PDCCH belongs to the second group, data is transmitted only on the first carrier in a subframe indicated by the CIF value.
