Supporting power savings in multi-modal xr services

Abstract

Systems, methods, and instrumentalities are described herein associated with supporting power savings in multi-modal services (e.g., XR services). Dynamic and coordinated power saving schemes may be supported, for example, in multi-modal XR services. A wireless transmit/receive unit (WTRU) may be used to enable power savings. A WTRU (e.g., anchor WTRU) may receive information (e.g., via an application or higher layer message(s)) indicating an association between flows and/or other WTRUs (e.g., collaborative group). The anchor WTRU may receive configuration information for a first member WTRU indicating a first set of parameters, a second set of parameters, and a threshold. The anchor WTRU may determine a first duration (e.g., DRX-UL-Gap) associated with the first set of parameters and an expected UL traffic associated with the first member WTRU. The anchor WTRU may send an indication indicating the (e.g., preferred) second set of parameters, for example, if the duration exceeds the threshold.
