Publication number: 20240089766Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Inventors: Yuchul KIM, Huilin XU, Hwan Joon KWON, Peter Pui Lok ANG, Jay Kumar SUNDARARAJAN, Krishna Kiran MUKKAVILLI, Yeliz TOKGOZ, Jing LEI, Tingfang JI, Ravi AGARWAL, Seyong PARK
