Abstract
The present invention provides a method for a base station to transmit a downlink signal in a wireless communication system, the method comprising: allocating a resource to a downlink signal; and transmitting the downlink signal using the allocated resource. In the downlink signal transmission method and apparatus thereof, a resource for transmitting a Physical Downlink Shared Channel (PDSCH) among the downlink signals is allocated from a specific OFDM symbol that is fixed within a subframe.
Claims16
A method for receiving a PDSCH (Physical Downlink Shared Channel) signal by a communication apparatus in a wireless communication system, comprising:
- receiving a RRC (Radio Resource Control) signal including information used for identifying a region from which the PDSCH signal is received;
- receiving a PDCCH (Physical Downlink Control Channel) signal including resource allocation information for the PDSCH signal;
- and
- receiving the PDSCH signal from a starting OFDM (Orthogonal Frequency Division Multiplexing) symbol of the region,
- wherein the PDCCH signal is received on a first downlink component carrier and the PDSCH signal is received on a second downlink component carrier which is different from the first downlink component carrier.
A communication apparatus for receiving a PDSCH (Physical Downlink Shared Channel) signal in a wireless communication system, comprising:
- a RF (Radio Frequency) module;
- and
- a processor,
- wherein the processor is configured to:
- receive a RRC (Radio Resource Control) signal including information used for identifying a region from which the PDSCH signal is received;
- receive a PDCCH (Physical Downlink Control Channel) signal including resource allocation information for the PDSCH signal;
- and
- receive the PDSCH signal from a starting OFDM (Orthogonal Frequency Division Multiplexing) symbol of the region,
- wherein the PDCCH signal is received on a first downlink component carrier and the PDSCH signal is received on a second downlink component carrier which is different from the first downlink component carrier.
