Abstract
The present invention relates to methods and devices for transmitting/receiving downlink signals in a wireless communication system. The methods and devices according to the present invention receive a downlink grant for user equipment (referred to hereinafter as a first downlink grant) at a first of a plurality of resource units in a given resource region from a base station; and detect an uplink grant at a second of the plurality of resource units if resource assignment information in the first downlink grant has a first value, and detect downlink data at the resource unit if the resource assignment information has a second value.
Claims8
A method for receiving, by a user equipment, a downlink signal in a wireless communication system, the method comprising:
- receiving a downlink grant for the user equipment (hereinafter, a first downlink grant) on a first resource unit among a plurality of resource units in a predetermined resource region;
- and
- detecting an uplink grant on a second resource unit among the resource units when resource assignment information in the first downlink grant has a first value and detecting downlink data on the resource unit when the resource assignment information has a second value.
A user equipment for receiving a downlink signal in a wireless communication system, the user equipment comprising:
- a radio frequency (RF) unit configured to transmit/receive a signal;
- and
- a processor configured to control the RF unit,
- wherein the processor controls the RF unit to receive a downlink grant for the user equipment (hereinafter, a first downlink grant) on a first resource unit among a plurality of resource units in a predetermined resource region;
- and
- the processor detects an uplink grant on a second resource unit among the resource units when resource assignment information in the first downlink grant has a first value and detects downlink data on the resource unit when the resource assignment information has a second value.
A method for transmitting, by a base station, a downlink signal in a wireless communication system, the method comprising:
- transmitting a downlink grant for a user equipment (hereinafter, a first downlink grant) to the user equipment on a first resource unit among a plurality of resource units in a predetermined resource region;
- and
- transmitting an uplink grant or downlink data to the user equipment on a second resource unit among the resource units, wherein the first downlink grant includes assignment information having a first value when the uplink grant is transmitted on the second resource unit and the first downlink grant includes assignment information having a second value when the downlink data is transmitted on the second resource unit.
A base station for transmitting a downlink signal in a wireless communication system, the base station comprising:
- a radio frequency (RF) unit configured to transmit/receive a signal;
- and
- a processor configured to control the RF unit,
- wherein the processor controls the RF unit to transmit a downlink grant for a user equipment (hereinafter, a first downlink grant) to the user equipment on a first resource unit among a plurality of resource units in a predetermined resource region and controls the RF unit to transmit an uplink grant or downlink data to the user equipment on a second resource unit among the resource units, and
- wherein the first downlink grant includes assignment information having a first value when the uplink grant is transmitted on the second resource unit and the first downlink grant includes assignment information having a second value when the downlink data is transmitted on the second resource unit.
