US 11,889,516 B2 · Method and apparatus for transmitting or receiving feedback information in communication system

Abstract

Disclosed are a method and an apparatus for transmitting or receiving feedback information in a communication system. An operation method of a terminal comprises the steps of: receiving, from a base station, DCI #1 including scheduling information of PDSCH #1 and transmission resource information of HARQ response #1 with respect to PDSCH #1; receiving, from the base station, DCI #2 including scheduling information of PDSCH #2 and transmission resource information of HARQ response #2 with respect to PDSCH #2; and when the transmission resource information of HARQ response #1 is configured as undefined, transmitting, to the base station, HARQ response #1 and HARQ response #2 by using a resource indicated by the transmission resource information of HARQ response #2. Therefore, the performance of the communication system can be improved.

Dependent claims

An operation method of a terminal in a communication system, the operation method comprising:

receiving downlink control information (DCI) #1 from a base station, the DCI #1 including scheduling information of a physical downlink shared channel (PDSCH) #1 and transmission resource information of a hybrid automatic repeat request (HARQ) response #1 for the PDSCH #1;
receiving the PDSCH #1 from the base station based on the scheduling information included in the DCI #1;
receiving DCI #2 from the base station, the DCI #2 including scheduling information of a PDSCH #2 and transmission resource information of an HARQ response #2 for the PDSCH #2;
receiving the PDSCH #2 from the base station based on the scheduling information included in the DCI #2;
and
when the transmission resource information of the HARQ response #1 is configured as undefined, transmitting the HARQ response #1 and the HARQ response #2 to the base station by using a resource indicated by the transmission resource information of the HARQ response #2.
