US 2020/0288479 A1 · BEAM MANAGEMENT IN A WIRELESS NETWORK

Abstract

A wireless transmit/receive unit (WTRU) may monitor control resource sets (CORESETs) to receive a physical downlink control channel (PDCCH) having downlink control information (DCI) that includes a scheduling offset and an indicated beam for a scheduled physical downlink shared channel (PDSCH) reception. When the scheduling offset of the scheduled PDSCH is less than a threshold, a default beam of a transmission configuration indication (TCI) state may be utilized to receive the scheduled PDSCH. When the scheduling offset of the scheduled PDSCH is more than a threshold, the indicated beam is utilized to receive the scheduled PDSCH on a condition that a measured quality is above a measurement threshold or the default beam may be utilized when the measured quality is below the measurement threshold.

Dependent claims

A wireless transmit/receive unit (WTRU) comprising:

a transceiver;
and
a processor,
the transceiver configured to monitor a plurality of configured control resource sets (CORESETs) to receive a downlink control information (DCI) on a physical downlink control channel (PDCCH), wherein the DCI includes scheduling information for a data transmission on a physical downlink shared channel (PDSCH) reception;
the processor configured to determine a default beam of a reference CORESET from among the plurality of configured CORESETs, wherein the reference CORESET is determined based on at least one of a slot, a slot number, configured CORESETs monitored in the slot, and CORESET time location with respect to the data transmission on the PDSCH,
wherein, on a condition that a scheduling offset of the data transmission on the PDSCH is less than a threshold, the processor is configured to receive the data transmission on the PDSCH using the default beam of the reference CORESET.
