US 2018/0295643 A1 · METHOD FOR TERMINAL FOR CARRYING OUT CARRIER AGGREGATION IN WIRELESS COMMUNICATION SYSTEM AND TERMINAL UTILIZING THE METHOD

Abstract

The present method, for a terminal carrying out carrier aggregation in a wireless communication system, comprises the steps of: receiving, from a base station, at least one downlink grant; determining whether or not the at least one downlink grant corresponds to a valid downlink grant; and on the basis of the determination, transmitting a physical uplink control channel (PUCCH), wherein the PUCCH transmission step, on the basis of the determination, comprises the steps of: if a downlink grant included in the at least one downlink grant is a valid down grant, then transmitting a PUCCH associated with the valid downlink grant; and if a downlink grant included in the at least one downlink grant is not a valid down grant,

Claims13

Dependent claims

A method for carrier aggregation (CA) performed by a user equipment in a wireless communication system, the method comprising:

receiving at least one downlink grant from an eNB;
determining whether the at least one downlink grant corresponds to a valid downlink grant;
and
performing physical uplink control channel (PUCCH) transmission based on the determination,
wherein the step of performing the PUCCH transmission based on the determination comprises:
performing PUCCH transmission related to a valid downlink grant if a downlink grant included in the at least one downlink grant is a valid downlink grant;
and
not performing PUCCH transmission related to an invalid downlink grant if a downlink grant included in the at least one downlink grant is an invalid downlink grant.
