Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use the techniques described herein to reattempt a video telephony (VT) call after receiving a rejection message indicating that a prior attempt at the VT call failed. In some cases, the UE may have a first configuration indicating that the UE is to redial VT calls exclusively using packet-switched (PS) networks. In other cases, the UE may have a second configuration indicating that the UE is to switch to a circuit-switched (CS) network after one or more failed attempts at the VT call using PS networks. In any case, once the UE receives a rejection message in response to a prior attempt at a VT call, the UE may reattempt the VT call based on a rejection cause in the rejection message and whether the UE has the first configuration or the second configuration.

Abstract: In response to receiving instructions from a Spectrum Access System (SAS) to modify (e.g., reduce and/or cease) network transmissions in one or more Citizens Broadband Radio Service (CBRS) sub-bands following the SAS's detection of incumbent activity, the network's Operation Support System (OSS) predicts or measures received signal strength (RSS) levels based on the SAS's original instructions, estimates RSS levels based on modified versions of the SAS's instructions that prioritize higher-NPV (net present value) CBRS base stations (CBSDs) over lower-NPV CBSDs, selects a modified version whose RSS levels are approximately the same as or less than the RSS levels of the SAS's original instructions, and transmits to the SAS requests for the selected modified version. In this way, the OSS can achieves more-efficient allocation of the CBRS spectrum and therefore more-desirable network communications without interfering with the incumbent's communications.
