Wake-up signals and dormancy status signals for selected physical channel identifiers

Abstract

In an aspect, a BS transmits a WUS that includes an indication of selected PCIs of a PCI group to a UE. The UE receives the WAS and monitors one or more configured DRX ON durations associated with the selected PCIs of the PCI group. In another aspect, a BS transmits a signal that includes dormancy status information for a set of selected PCIs to a UE. For each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a dormant state, the UE refrains from PDCCH monitoring on a dormant BWP to which the respective PCI transitions. For each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a non-dormant state, the UE performs PDCCH monitoring on a non-dormant BWP to which the respective PCI transitions.

What is claimed is:

 receiving a signal that includes dormancy status information for a set of selected physical cell identifiers (PCIs);   for each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a dormant state, refraining from Physical Downlink Control Channel (PDCCH) monitoring on a dormant bandwidth part (BWP) to which the respective PCI transitions; and   for each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a non-dormant state, performing PDCCH monitoring on a non-dormant BWP to which the respective PCI transitions.
