Abstract: A multi-mode communication device having a scan optimizer capable of prioritizing scan frequencies for different radio access technologies (RATs) during a network search. The scan frequency prioritization may be based on various network coverage considerations associated with RAT availability, RAT density within a region, geographic location, historic attachment for the multi-mode device, an operation mode of the multi-mode device, etc. The multimode device can utilize its scan optimizer to generate an optimized scan schedule to be employed for a limited duration during a network search to improve its likelihood of success in detecting and/or attaching to a network associated with a prioritized RAT. A default scan schedule having equal scan frequency prioritization can be employed by the multi-mode device at a time when the limited duration of the optimized scan schedule expires and no networks associated with a prioritized RAT have been acquired.
Abstract translation: 一种具有扫描优化器的多模式通信设备，其能够在网络搜索期间优先考虑不同无线电接入技术（RAT）的扫描频率。 扫描频率优先级可以基于与RAT可用性，区域内的RAT密度，地理位置，多模式设备的历史连接，多模式设备的操作模式等相关联的各种网络覆盖考虑。多模设备 可以利用其扫描优化器来产生在网络搜索期间在有限持续时间内使用的优化扫描调度，以提高其在检测和/或附着到与优先化RAT相关联的网络的成功的可能性。 在优化的扫描计划的有限持续时间到期并且没有获得与优先化的RAT相关联的网络的时候，多模式设备可以采用具有相同扫描频率优先级的默认扫描调度。

Abstract: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

Abstract: Various systems and methods disclosed herein describe improvements for beam management that leverage virtualization across a vertical polarization (V-Pol) and horizontal polarization (H-Pol). One or more of a user equipment (UE) and a base station may include an antenna array comprising V-Pol antenna elements and H-Pol antenna elements. The UE may determine a number of receive (Rx) beam of an Rx beam sweep are needed, signal this number to the base station, and perform the beam sweep according to one or both of the V-Pol and H-Pol. A UE may use group based beam reporting to indicate to the base station a transmit (Tx) beam upon which downlink MIMO using V-Pol and H-Pol may be supported by reporting a same transmission configuration indication (TCI) corresponding to the Tx beam for both a first Rx beam and a second Rx beam in a group based beam reporting message.
