Abstract

Methods, systems, and devices for wireless communication are described. In a wireless communications system, a network entity may configure a set of monitoring occasion configurations that correspond to (e.g., are linked to) a set of energy saving modes. A user equipment (UE) may receive control signaling from the network entity indicating the configuration, and the UE may switch from a first energy saving mode to a second energy saving mode. Based on the switching, and because the energy saving modes are linked to the monitoring occasion configurations, the UE may switch from a first monitoring occasion configuration corresponding to the first energy saving mode to a second monitoring occasion configuration corresponding to the second energy saving mode. The UE may monitor a control channel in accordance with the second monitoring occasion configuration.
