Method for channel allocating in wireless access system
First Claim
1. A method for receiving downlink data in a wireless access system which supports multi-radio frequency bands, the method comprising:
- receiving, by a user equipment (UE) from a base station (BS), a physical downlink control channel (PDCCH) on a primary frequency band, the PDCCH including;
control information associated with a scheduled frequency band on which the downlink data is to be transmitted; and
an indication indicating the scheduled frequency band among the multi-radio frequency bands, the multi-radio frequency bands comprising a plurality of PDCCHs indicating which physical channel is indicated by each PDCCH; and
receiving, by the UE from the BS, the downlink data through the scheduled frequency band that is indicated by the indication and is included in the multi-radio frequency band, wherein;
if the downlink data is a voice over internet protocol (VoIP) data, the scheduled frequency band is only the primary frequency band, andif the downlink data is not a VoIP data, the downlink data is received through the scheduled frequency band indicated by the indication, wherein each of frequency bands included in the multi-radio frequency band has a center frequency, and wherein each of the frequency bands is configured with plurality of physical channels.

Abstract
A method for allocating uplink and downlink physical channels to improve throughput of a wireless access system is disclosed. A method for allocating channels to optimize a wireless access system which supports radio frequencies comprises configuring one or more physical channels in a transmitter; allocating first physical channels to a receiver considering features of the one or more physical channels; and transmitting one or more control channels to the receiver through a predetermined physical channel of the first physical channels, the control channels including configuration information of the first physical channels allocated to the receiver.

6. An user equipment (UE) for receiving downlink data in a wireless access system which supports multi-radio frequency bands, the UE comprising:
-
a processor for supporting the reception of the downlink data through the multi-radio frequency band; and
reception antennas, wherein the processor is configured to;
receive, from a base station (BS), a physical downlink control channel (PDCCH) only on a primary frequency band by using the reception antennas, the PDCCH including;
control information associated with a scheduled frequency band on which the downlink data is transmitted; and
an indication indicating the scheduled frequency band among the multi-radio frequency bands, the multi-radio frequency bands comprising a plurality of PDCCHs indicating which physical channel is indicated by each PDCCH, and receive, from the BS, voice over internet protocol (VoIP) the downlink data through the scheduled frequency band that is indicated by the indication and is included in the multi-radio frequency band by using the reception antennas, wherein;if the downlink data is a voice over internet protocol (VoIP) data, the scheduled frequency band is only the primary frequency band, and if the downlink data is not a VoIP data, the downlink data is received through the scheduled frequency band indicated by the indication, wherein each of frequency bands included in the multi-radio frequency band has a center frequency, and wherein each of the frequency bands is configured with plurality of physical channels. - View Dependent Claims (7, 8, 9, 10, 11)
