Abstract: Techniques to maximize connectivity to a preferred radio access technology (RAT) (e.g., 5G NR) over a less preferred RAT (e.g., 4G LTE) are disclosed. When a user equipment (UE) is camped on a preferred RAT connectivity capable cell (e.g., NR cell, EUTRA dual-connectivity (ENDC) cell), offsets or biases may be applied to delay triggering of a cell reselection. When UE is camped on a non-preferred RAT connectivity capable cell, offset(s) may be applied to accelerate triggering of the cell reselection. When cell reselection is triggered, offsets or biases may be applied to favor reselection to preferred RAT connectivity capable cell over a non-preferred RAT connectivity capable cell.

Abstract: Techniques are provided for network mode selection based on positioning system information blocks (SIBs). An example method for measuring positioning reference signals with a user equipment includes receiving one or more system information blocks containing positioning reference signal information, determining band and frequency information for positioning reference signals based on the one or more system information blocks, determining at least one operational constraint for the user equipment, determining a network mode for the user equipment based at least on the band and frequency information and the at least one operational constraint, and measuring one or more positioning reference signals based at least in part on the network mode.

Abstract: A method of wireless communications by a user equipment (UE) includes detecting, in response to a bandwidth part (BWP) switch, a first BWP of a first carrier aggregation signal and a second BWP of a second carrier aggregation signal. The first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal are each within a predetermined frequency range of each other. The method also includes tuning a radio frequency (RF) channel to a center of a wideband channel including the first BWP and the second BWP. The method further includes processing the wideband channel including both the first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal with a single phase locked loop (PLL).

Abstract: Disclosed are techniques for performing positioning measurements at a mobile device during a positioning session with a serving cell. In an aspect, the mobile device determines to trigger a coverage-enhanced (CE) mode before a positioning session timeout for the positioning session expires, continues performance of the positioning measurements during the positioning session with the serving cell while the mobile device remains connected to the serving cell due to the triggered CE mode, determines whether the positioning measurements have been completed or the positioning session timeout has expired, and responsive to the determination that the positioning measurements have been completed or that the positioning session timeout has expired, reports, to a network entity in the wireless communications network, actual handover measurements to enable the network entity to make a handover determination.

Abstract: In techniques disclosed allow a user equipment (UE) that receives location assistance data to determine a preferred bandwidth part (BWP) with which reference signals from one or more base stations can be measured for position determination of the UE. The selection of the preferred BWP can be based on a determination of the frequency and bandwidth of reference signals to be transmitted by the one or more base stations over the course of a positioning station. The preferred BWP may be the BWP, of a plurality of candidate BWPs, that allows for a desired number of reference signal measurements to be taken without retuning a transceiver of the UE.

Abstract: A user equipment (UE) includes a processor configured to: send a first signal but not a second signal in response to the first and second signals being scheduled for concurrent transmission and available power for transmission of the first signal for the concurrent transmission being insufficient for detection of the first signal, the first signal being a first radio access technology (RAT) positioning reference signal; set a power sharing mode of the UE to a static power sharing mode; indicate that the UE is in a single-uplink operating mode with respect to the first RAT and the second RAT; and/or select a second-RAT TRP, for receiving the second signal, that has a maximum UE transmission power no greater than a threshold power in response to the initiation of the positioning session.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for identifying one or more preferred bandwidth parts (BWPs) based on radio frequency (RF) performance degradation considerations. For example, a preferred BWP may be selected in an effort to avoid self-interference, to avoid voltage controlled oscillator pulling, to avoid thermal throttling, to enable or improve the use of multiple subscriber identification modules (MSIMs), or a combination thereof. In a general aspect, an example of the disclosed techniques by a user equipment (UE) include receiving signaling that configures the UE with a number of BWPs from a network entity, determining a preferred BWP based on an amount of RF performance degradation associated with one or more of the number of BWPs, and signaling the preferred BWP to the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT, and that a second SIM has been activated for the UE. The UE may determine, based at least in part on user input, whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or to operate in a single SIM mode where only the first SIM, and not the second SIM, is active. The UE may selectively deactivate the second SIM based at least in part on determining whether to operate in the multi-SIM mode or the single SIM mode. Numerous other aspects are provided.
