Abstract: Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.

Abstract: This application sets forth techniques for mitigating radio frequency (RF) interference from wired connections on cellular wireless reception quality, including pre-emptively determining when to perform RF interference mitigation based on various factors. An interference mitigation module in the wireless device determines whether to perform an interference mitigation procedure based on active and/or imminent use of a high-speed wired connection port for data transfer in parallel with a cellular wireless connection that uses a mid-frequency RF band or a high-frequency RF band. The wireless device determines a target cell in a low-frequency RF band and biases measurement reports sent to a cellular wireless network to handover and keep the cellular wireless connection to the target cell in the low-frequency RF band while a high-speed wired connection is active.

Abstract: This application describes methods and apparatus to manage data transport across multiple radio links for 5G-capable wireless devices. Under certain criteria, including performance of at least one radio link, a mobility state of a 5G-capable wireless device, and data transport requirements for a latency sensitive application session, the 5G-capable wireless device sends buffer status report (BSR) requests for one or more both of the radio links to prioritize and transition uplink (UL) data between radio links before a measurement reporting threshold is met. In some embodiments, the 5G-capable wireless device proactively sends BSR requests for radio resources before the UL data is generated by the latency sensitive application session. In some embodiments, the 5G-capable wireless device duplicates UL data for the latency sensitive application session across multiple radio links.

Abstract: Embodiments include a user equipment (UE) and methods performed by the UE. The methods include receiving a measurement configuration request from a network, in response to the measurement configuration request, measuring a quality of one or more uplink (UL) carrier aggregation (CA) combinations, wherein each UL CA combination comprises a plurality of component carriers, generating a message that includes the quality of the one or more UL CA combinations and transmitting the message to the network. Further embodiments include the above operations being performed as a set of instructions executed by a processor or an integrated circuit that includes circuitry to perform the operations.

Abstract: The exemplary embodiments describe devices, systems and methods for implementing various exemplary techniques related to fifth generation (5G) new radio (NR) cell search. A user equipment (UE) selects a frequency band to scan during a cell search procedure and identifies a frequency within the frequency band that is associated with a synchronization signal block (SSB) based on an indication of the frequency stored locally at the UE prior to the cell search procedure. The UE then scans the frequency for the SSB and determines that the SSB has been broadcast by a cell over the frequency.

Abstract: A user equipment (UE) may skip certain measurements when it is unlikely that the UE will use the measurements. The UE determines that the UE is configured with one of a measurement gap or gapless measurements, identifies that a predetermined condition has been satisfied and implements a mitigation technique in response to identifying that the predetermined condition has been satisfied, wherein the mitigation technique includes omitting performing one of a measurement during the measurement gap or a gapless measurement, wherein the measurement or the gapless measurement corresponds to a first radio access technology (RAT) that is different than a second RAT on which the UE is currently camped.
