CPC H04W 72/23 (2023.01) [H04W 24/10 (2013.01); H04W 72/0446 (2013.01)] | 13 Claims |
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station (BS), physical downlink control channel (PDCCH) configuration information including two different values of a control resource set (CORESET) pool index;
receiving, from the BS, information indicating that a pre-defined quasi co located (QCL) relation is enabled to be applied based on the CORESET pool index;
receiving, from the BS, a PDCCH triggering an aperiodic channel state information reference signal (CSI-RS);
receiving, from the BS, the aperiodic CSI-RS; and
transmitting, to the base station, information indicating whether the terminal supports the pre-defined QCL relation to be applied based on the CORESET pool index value,
wherein, in case that a scheduling offset between a last symbol of the PDCCH triggering the aperiodic CSI-RS and a start symbol of the aperiodic CSI-RS is smaller than a time duration for QCL application, a QCL relation applied for the aperiodic CSI-RS is determined according to a CORESET pool index value associated with the PDCCH triggering the aperiodic CSI-RS.
