Abstract
Provided is a method and a device for transmitting an Ack/Nack of sPUCCH in response to the reception of short TTI-based sPDSCH in a 3GPP LTE/LTE-Advanced system. A base station may set, for each terminal, an offset value for setting a link between sPDSCH and sPUCCH, and transmit the set offset value to the terminal through upper layer signaling (RRC signaling), thereby enabling a terminal to use the offset value to allocate sPUCCH resources for transmitting an Ack/Nack in response to the reception of sPDSCH.
Claims9
A method of transmitting a short uplink physical control channel (sPUCCH), the method comprising:
- receiving a downlink data channel from a base station;
- receiving an user equipment (UE)-specific offset value to transmit the sPUCCH for the downlink data channel through higher layer signaling;
- and
- transmitting the sPUCCH including ACK/NACK information for the downlink data channel through a resource determined based on the UE-specific offset value,
- wherein a 2-bit value of a sPUCCH field is included in a downlink control information (DCI) for determining the resource to transmit the sPUCCH for the downlink data channel.
A method of receiving a short uplink physical control channel (sPUCCH), the method comprising:
- transmitting a downlink data channel to a user equipment;
- transmitting an user equipment (UE)-specific offset value to receive the sPUCCH for the downlink data channel through higher layer signaling;
- and
- receiving the sPUCCH including ACK/NACK information for the downlink data channel through a resource determined based on the UE-specific offset value,
- wherein a 2-bit value of a sPUCCH field is included in a downlink control information (DCI) for determining the resource to receive the sPUCCH for the downlink data channel.
A user equipment for transmitting a short uplink physical control channel (sPUCCH), the user equipment comprising:
- a receiver configured to receive a downlink data channel from a base station and receive an user equipment (UE)-specific offset value to transmit the uplink control channel for the downlink data channel through higher layer signaling;
- and
- a controller configured to determine a resource for transmitting the sPUCCH based on the offset value and transmit the sPUCCH,
- wherein a 2-bit value of a sPUCCH field is included in a downlink control information (DCI) for determining the resource to transmit the sPUCCH for the downlink data channel.
