Abstract
The present invention relates to a method and an apparatus for receiving a signal from a terminal in a wireless communication system supporting reconfiguration of a wireless resource. Specifically, the present invention comprises the method for receiving, during a reconfiguration period, a plurality of reconfiguration messages from a subframe at a location indicated by means of upper layer signaling, wherein the plurality of reconfiguration messages indicate the same uplink-downlink configuration within the reconfiguration period.
Claims8
A method for receiving a signal by a user (UE) equipment in a wireless communication system supporting reconfiguration of a wireless resource, the method comprising:
- receiving, via radio resource control (RRC) signaling, a configuration associated with a physical downlink control channel (PDCCH) for reconfiguring a time division duplex (TDD) uplink-downlink (UL-DL) configuration of the UE,
- wherein the configuration associated with the PDCCH includes information on a periodicity as a N number of subframes, the N number of subframes is longer than 10 subframes, and a time length of one subframe is 1 ms, and
- wherein the configuration associated with the PDCCH includes information on positions of several subframes in which the PDCCH is to be monitored within the periodicity, and a number of the several subframes is less than the N number of subframes;
- and
- monitoring a plurality of reconfiguration commands in the PDCCH in the positions of the several subframes within each interval of the periodicity based on the configuration associated with the PDCCH,
- wherein the plurality of reconfiguration commands include a same first TDD UL-DL configuration within a first interval of the periodicity,
- wherein the TDD UL-DL configuration of the UE is reconfigured to the same first TDD UL-DL configuration within a second interval of the periodicity, and the second interval is an immediate next interval from the first interval of the periodicity,
- wherein the plurality of reconfiguration commands include a same second TDD UL-DL configuration within the second interval of the periodicity,
- wherein the same second TDD UL-DL configuration is different from the same first TDD UL-DL configuration, and
- wherein each interval of the periodicity is the same as the N number of subframes.
A user equipment (UE) for receiving a signal in a wireless communication system supporting reconfiguration of a wireless resource, the UE comprising:
- a receiver;
- and
- a processor,
- wherein the processor is configured to:
- control the receiver to receive, via radio resource control (RRC) signaling, a configuration associated with a physical downlink control channel (PDCCH) for reconfiguring a time division duplex (TDD) uplink-downlink (UL-DL) configuration of the UE,
- wherein the configuration associated with the PDCCH includes information on a periodicity as a N number of subframes, the N number of subframes is longer than 10 subframes, and a time length of one subframe is 1 ms, and
- wherein the configuration associated with the PDCCH includes information on positions of several subframes in which the PDCCH is to be monitored within the periodicity, and a number of the several subframes is less than the N number of subframes, and
- monitor a plurality of reconfiguration commands in the PDCCH in the positions of the several subframes within each interval of the periodicity based on the configuration associated with the PDCCH,
- wherein the plurality of reconfiguration commands include a same first TDD UL-DL configuration within a first interval of the periodicity,
- wherein the TDD UL-DL configuration of the UE is reconfigured to the same first TDD UL-DL configuration for a second interval of the periodicity, and the second interval is an immediate next interval from the first interval of the periodicity,
- wherein the plurality of reconfiguration commands include a same second TDD UL-DL configuration within the second interval of the periodicity,
- wherein the same second TDD UL-DL configuration is different from the same first TDD UL-DL configuration, and
- wherein each interval of the periodicity is the same as the N number of subframes.
