Samsung patents method to improve 5G signal reception in crowded networks

1. A method performed by a terminal in a communication system, the method comprising: receiving, from a base station, downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH); identifying that a scheduling offset for the PDSCH is smaller than a time duration for applying quasi co-location (QCL) information; identifying a first control resource set (CORESET) with a lowest identity (ID) monitored in a slot closest to a slot for PDSCH reception; identifying one or more default beams for the PDSCH based on the first CORESET; identifying a second CORESET overlapping in time with the PDSCH, wherein the second CORESET corresponds to two transmission configuration indicator (TCI) states; identifying a beam for the PDSCH; and receiving, from the base station, the PDSCH based on the beam, wherein, in case that a number of default beams for the PDSCH is one and the one default beam for the PDSCH overlaps with a TCI state among the two TCI states corresponding to the second CORESET, the beam for the PDSCH is identified based on the TCI state overlapping with the one default beam for the PDSCH, wherein, in case that a number of default beams for the PDSCH is one and the one default beam for the PDSCH does not overlap with the two TCI states corresponding to the second CORESET, the beam for the PDSCH is identified based on one TCI state among the two TCI states corresponding to the second CORESET, wherein, in case that a number of default beams for the PDSCH is two and at least one of the two TCI states corresponding to the second CORESET overlaps with the two default beams for the PDSCH, the beam for the PDSCH is identified based on the two TCI states corresponding to the second CORESET, wherein, in case that the number of default beams for the PDSCH is two and the two TCI states corresponding to the second CORESET do not overlap with the two default beams for the PDSCH, the beam for the PDSCH is identified based on one of the two default beams for the PDSCH and one of the two TCI states corresponding to the second CORESET, and wherein the PDSCH and the second CORESET are received based on an intra-band carrier aggregation (CA).
