Description

The embodiments of this disclosure, as a whole, relate to the field of telecommunications, and more particularly to communication methods, apparatus, and computer storage media. Several techniques have been proposed to improve communication performance. Discontinuous reception (DRX) is a method employed in various wireless technologies to allow terminal devices to turn off their receivers during periods of inactivity. DRX can be employed in both RRC idle mode and RRC connected mode. In a communication system, terminal devices are configured to use DRX to reduce power consumption, and are expected to monitor one paging occasion (PO) per DRX cycle. In RRC idle mode, the DRX cycle is based on the paging cycle, as terminal devices are expected to receive only paging messages. In RRC connected mode, terminal devices need to monitor the physical downlink control channel (PDCCH) search space for possible indications of incoming traffic.
