The provisioning system may obtain UE metrics through the SMF or an Access and Mobility Management Function (AMF) in a like manner. The provisioning system may obtain Radio Access Network (RAN) metrics through the SMF or AMF in a like manner.

Abstract: Methods and systems for citizens broadband radio service (CBRS) interference management using dual subscriber identification module (SIM) devices are described. The method includes assigning a physical cell identity (PCI) to each CBRS device (CBSD) granted unlicensed spectrum by a spectrum access system (SAS). Each spectrum granted CBSD may exchange PCIs with neighbor spectrum granted CBSDs to resolve PCIs and maintains a PCI table. A dual SIM device may be connected to a CBSD via a first SIM. Each spectrum granted CBSD having a connected dual SIM device reports a number of PCIs detected by the dual SIM device(s). A SAS designated dual SIM device may use a second SIM to measure power values of PCIs detected by the designated dual SIM device which are absent from a provided PCI table. The measured power values may be used by the SAS to make cluster interference decisions.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network may schedule a user equipment (UE) for multiple transmission/reception point (TRP) communication. The network may transmit a single downlink control information (DCI) message to the UE to dynamically configure multiple transmission configuration indicator (TCI) states for the multiple TRPs. In a first example, the DCI message may include a bit field indicating a set of antenna ports and the multi-TRP scheme for transmission. In a second example, the DCI message may include a separate field indicating the multi-TRP scheme (e.g., based on UE capabilities). In a third example, the DCI may indicate redundancy versions (RVs) for different TRPs in an RV field or across multiple fields. In a fourth example, the DCI may include an indication of a precoding resource block group (PRG) size that may be interpreted differently based on the indicated multi-TRP scheme.
