1. A method for a physical downlink control channel (PDCCH) monitoring of a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a first transmit-receive point (TRP), first information regarding a plurality of control resource sets (CORESETs), the first information providing for each CORESET of the plurality of CORESETs:
i) a CORESET index,
ii) a PDCCH demodulation reference signal (DM-RS) scrambling sequence initialization value,
iii) a CORESET time duration in number of symbols,
iv) a set of resource blocks,
v) control channel element (CCE)-to-resource element group (REG) mapping parameters,
vi) an antenna port quasi co-location indicating quasi co-location information of a DM-RS antenna port for PDCCH reception, and
vii) an indication of presence of transmission configuration indication (TCI) field for a specific downlink control information (DCI) format;
receiving, from the first TRP, second information which reports a first configuration among a plurality of configurations related to the PDCCH monitoring,
wherein the first configuration reports a combination of a first resource pattern index and a first PDCCH CORESET index;
performing a first PDCCH monitoring in a first CORESET indicated by the first PDCCH CORESET index and communicating with the first TRP using a first resource pattern indicated by the first resource pattern index,
wherein the first resource pattern comprises more downlink resources than uplink resources in a slot;
transmitting, to the first TRP, a scheduling request for uplink transmission;
in response to the scheduling request, receiving, from the first TRP, a second configuration for a second TRP,
wherein the second configuration reports a combination of a second resource pattern index and a second PDCCH CORESET index; and
performing a second PDCCH monitoring in a second CORESET indicated by the second PDCCH CORESET index and communicating with the second TRP using a second resource pattern indicated by the second resource pattern index,
wherein the second resource pattern comprises more uplink resources than downlink resources in a slot.
