Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a network device, a first configuration for a set of UL resources, and determines a time window for the set of UL resources.

In this way, an UL resource may be determined based on a time window associated with a DRX cycle, and a UL triggered DRX may be achieved. Thus, an alignment between DL and UL transmissions may be facilitated and power saving may be improved.
