Abstract
The disclosure provides a method for scheduling an uplink control channel (PUCCH) in a next generation/5G wireless access network. The method of a terminal for scheduling a PUCCH may include: receiving, from a base station, timing relationship setting information between a downlink data channel (PDSCH) and a PUCCH; and scheduling the PUCCH on the basis of the timing relationship setting information.
Claims13
An operation method of a user equipment, the method comprising:
- receiving, from a base station via a physical downlink control channel (PDCCH), downlink control information (DCI) including timing relationship configuration information between a downlink (DL) and an uplink (UL) for a hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) feedback;
- and
- transmitting, to the base station, uplink control information via a physical uplink control channel (PUCCH) in a slot based on the timing relationship configuration information,
- wherein the uplink control information includes HARQ ACK/NACK feedback information with respect to a downlink data via a physical downlink shared channel (PDSCH), and
- wherein at least one, among plural subcarrier spacings (SCSs) including a first SCS for the DL and a second SCS for the UL, is selected as a reference.
2 more elements
A base station comprising:
- a receiver;
- a transmitter;
- and
- a controller which controls the receiver and the transmitter to:
- determine timing relationship configuration information between a downlink (DL) and an uplink (UL) for a hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) feedback;
- transmit, via a physical downlink control channel (PDCCH), downlink control information (DCI) including the timing relationship configuration information to a user equipment;
- and
- receive, from the user equipment, uplink control information via a physical uplink control channel (PUCCH) in a slot based on the timing relationship configuration information,
- wherein the uplink control information includes HARQ ACK/NACK feedback information, with respect to a downlink data via a physical downlink shared channel (PDSCH), and
- wherein at least one, among plural subcarrier spacings (SCSs) including a first SCS for the DL and a second SCS for the UL, is selected as a reference.
