Method and device for transceiving wireless signal in wireless communication system
The present invention relates to a wireless communication system and, particularly, to a method and a device therefor, the method comprising the steps of: configuring a plurality of A/N transmission delays and a plurality of A/N resources through a higher layer signal; receiving downlink scheduling information indicating a first A/N transmission delay among the plurality of A/N transmission delays and a first A/N resource among the plurality of A/N resources; receiving data indicated by the downlink scheduling information; and transmitting an A/N for the data by using the first A/N resource at a time determined on the basis of the first A/N transmission delay.
1. A method for transmitting a signal by a terminal in a wireless communication system, the method comprising:
configuring a plurality of acknowledgement/negative acknowledgment (A/N) transmission delays and a plurality of physical uplink control channel (PUCCH) resource sets through a higher layer signal, wherein each of the PUCCH resource sets corresponds to a respective A/N transmission delay;
receiving downlink scheduling information indicating a first A/N transmission delay among the plurality of A/N transmission delays;
receiving data indicated by the downlink scheduling information; and
transmitting an A/N for the data using a PUCCH resource at a time determined according to the first A/N transmission delay,
wherein a PUCCH resource set is selected from the plurality of PUCCH resource sets based on the first A/N transmission delay, and
wherein the PUCCH resource is selected from the PUCCH resource set based on (an index of a control channel element (CCE) used for reception of the downlink scheduling information) mod K, wherein K is a number of elements in the PUCCH resource set, and A mod B denotes a remainder obtained by dividing A by B.
2. The method according to claim 1 , wherein the plurality of A/N transmission delays is independently configured for each Hybrid Automatic Repeat Request (HARQ) process ID.
3. A terminal used in a wireless communication system, the terminal comprising:
a radio frequency (RF) transceiver; and
a processor,
wherein the processor is configured to:
configure a plurality of acknowledgment/negative acknowledgment (A/N) transmission delays and a plurality of physical uplink control channel (PUCCH) resource sets through a higher layer signal, wherein each of the PUCCH resource sets corresponds to a respective A/N transmission delay;
receive downlink scheduling information indicating a first A/N transmission delay among the plurality of A/N transmission delays;
receive data indicated by the downlink scheduling information; and
transmit an A/N for the data using a PUCCH resource at a time determined according to the first A/N transmission delay,
wherein a PUCCH resource set is selected from the plurality of PUCCH resource sets based on the first A/N transmission delay, and
wherein the PUCCH resource is selected from the PUCCH resource set based on (an index of a control channel element (CCE) used for reception of the downlink scheduling information) mod K, wherein K is a number of elements in the PUCCH resource set, and A mod B denotes a remainder obtained by dividing A by B.
4. The terminal according to claim 3 , wherein the plurality of A/N transmission delays is independently configured for each Hybrid Automatic Repeat Request (HARQ) process ID.
