Abstract: Methods, apparatus, and systems are described for assistance information from the UE to network side, e.g., enabling faster decision-making for secondary cell group deactivation in 3GPP MR DC/CA deployments. According to some aspects, instructions for UE behavior upon MR DC/CA secondary cell group activation are provided in a secondary cell group deactivation message to reduce delays for a UE triggered secondary group activation. RRC signaling ambiguities for conditional PSCell addition/ change may be resolved by a synchronization message between a main node and a secondary node to avoid delays and signaling errors.

Abstract: Radio network Positioning Reference Signals (PRSs) may be managed dynamically via user equipment (UE) requests triggered by measurements in accordance with initial PRS configurations, whereby a UE contacts an Access and Mobility Management Function (AMF) and/or a Location Management Function (LMF). Similarly, an LMF may initiate adjustments in PRS configurations and transmission via communications with base stations, UEs, and/or AMFs. Dynamic signaling of PRS configurations may be achieved via legacy protocols and/or New Radio Positioning Protocol A (NRPPa), for example. A requests from a UE for PRS configuration adjustment may include an indication of a required level of service or of a class of service, for example, and/or an indication of signal measurements, a position estimate, an indication of a capability of the UE.
