Abstract
Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes monitoring for a physical downlink control channel (PDCCH) in each of a plurality of monitoring occasions in a search space, wherein the PDCCHs are associated with the same downlink control information (DCI), and wherein the plurality of monitoring occasions are monitored using different beams; and decoding the PDCCHs after the monitoring.

A method for wireless communication by a user equipment (UE), comprising:
- monitoring for a physical downlink control channel (PDCCH) in each of a plurality of monitoring occasions in a search space, wherein the PDCCHs are associated with the same downlink control information (DCI), and wherein the plurality of monitoring occasions are monitored using different beams;
- decoding the PDCCHs after the monitoring;
- and
- transmitting an acknowledgement indicating that a channel has been successfully decoded, wherein the monitoring for the PDCCHs using the different beams is performed during a configured time window starting after the transmission of the acknowledgement.
A method for wireless communication by a user equipment (UE), comprising:
- monitoring for a physical downlink control channel (PDCCH) in each of a plurality of monitoring occasions in a search space, wherein the PDCCHs are associated with the same downlink control information (DCI), and wherein the plurality of monitoring occasions are monitored using different beams;
- decoding the PDCCHs after the monitoring;
- and
- receiving, on a channel from a BS, an indication of a switch from a first beam to a second beam;
- and
- transmitting an acknowledgement indicating that the channel is successfully decoded, wherein the monitoring for the PDCCHs using the different beams is performed during a configured time window starting after the transmission of the acknowledgement.
A method for wireless communication by a base station (BS), comprising:
- generating a physical downlink control channel (PDCCH) in each of a plurality of monitoring occasions in a search space, wherein the PDCCHs are associated with the same downlink control information (DCI), and wherein the PDCCHs in the plurality of monitoring occasions are transmitted using different beams;
- transmitting the PDCCHs;
- and
- receiving an acknowledgement indicating that a channel has been successfully decoded, wherein the transmission of the PDCCHs using the different beams is performed during a configured time window starting after the transmission of the acknowledgement.
