Abstract
The present invention relates to a method and an apparatus therefor, the method comprising the steps of: receiving control information for deactivating hybrid automatic repeat and request (HARQ) feedback; receiving a downlink signal on the basis of the HARQ feedback being deactivated; and transmitting, as channel state information (CSI), information on whether or not the downlink signal has been successfully decoded on the basis of a preset time point.
Claims10
A method by a user equipment (UE) comprising:
- receiving channel state information (CSI) report configuration information;
- receiving configuration information including bit information for identifying whether a hybrid automatic repeat and request (HARQ) feedback is enabled or disabled;
- receiving a downlink control channel including downlink control information,
- wherein the downlink control information includes resource assignment information for a downlink data channel;
- and
- receiving the downlink data channel based on the resource assignment information,
- wherein the HARQ feedback related to the downlink data channel is disabled based on the configuration information, and
- wherein, based on the downlink data channel being received within the latest N time units from a preconfigured time point, HARQ acknowledgement (ACK) information for the downlink data channel is transmitted as CSI based on the CSI report configuration information.

A user equipment comprising:
- at least one Radio Frequency (RF) unit;
- at least one processor;
- and
- at least one computer memory operably connected to the at least one processor and enabling the at least one processor to perform an operation when executed, the operation comprising:
- receiving channel state information (CSI) report configuration information;
- receiving configuration information including bit information for identifying whether a hybrid automatic repeat and request (HARQ) feedback is enabled or disabled;
- receiving a downlink control channel including downlink control information,
- wherein the downlink control information includes resource assignment information for a downlink data channel;
- and
- receiving a downlink data channel based on the resource assignment information;
- and
- wherein the HARQ feedback related to the downlink data channel is disabled based on the configuration information, and
- wherein, based on the downlink data channel being received within the latest N time units from a preconfigured time point, HARQ acknowledgement (ACK) information for the downlink data channel is transmitted as CSI based on the CSI report configuration information.

A method by a base station comprising:
- transmitting channel state information (CSI) report configuration information;
- transmitting configuration information including bit information for identifying whether a hybrid automatic repeat and request (HARQ) feedback is enabled or disabled to a user equipment;
- transmitting a downlink control channel including downlink control information,
- wherein the downlink control information includes resource assignment information for a downlink data channel;
- and
- transmitting the downlink data channel to the user equipment based on the resource assignment information,
- wherein the HARQ feedback related to the downlink data channel is disabled based on the configuration information, and
- wherein, based on the downlink data channel being received within the latest N time units from a preconfigured time point, HARQ acknowledgement (ACK) information for the downlink data channel is received as CSI based on the CSI report configuration information.
