Abstract: The present disclosure provides for the trigger of a beam refinement reference signal (BRRS) message. Triggering a BRRS message can include determining that a measured quality of a transmit and receive (Tx-Rx) beam pair is below the first value of the first quality threshold, the Tx-Rx beam pair corresponding to a current transmit (Tx) beam from an evolved node B (eNodeB) and the current receive (Rx) beam at the user equipment (UE), encoding a message for the eNodeB based on the determination that the quality of the Tx-Rx beam pair is below the quality threshold, wherein the message comprises a request for one or more BRRS, and processing the one or more BRRS to select a different Rx beam at the UE than the current Rx beam.

Abstract: A method for determining a signal propagation time mismatch in a modulator comprises generating a predetermined signal shape of a amplitude component of a radio frequency signal generating one or more predetermined conditions in a frequency component of the radio frequency signal at a first time interval relative to the predetermined signal shape and detecting the one or more predetermined conditions in the frequency component at a second time interval. The method further includes determining the amplitude component at the second time interval and calculating a signal propagation time mismatch value based on the signal shape of the amplitude component, on the first time interval and the second time interval.

A device may determine high performance communications circuitry and low performance communications circuitry within a first component of the device. The device may determine one or more high power radio frequency (RF) chains associated with at least one of a high frequency band or a low frequency band. The device may determine one or more low power RF chains associated with at least one of the high frequency band or the low frequency band. The device may perform a first operation with the high performance communications circuitry using a dynamically selected one of the one or more high power RF chains or the one or more low power RF chains and a second operation with the low performance communications circuitry using a dynamically selected one of the one or more low power RF chains or the one or more high power RF chains, wherein the dynamic selection is based at least in part on a use case, and wherein the first operation and the second operation are performed concurrently.

Abstract: Embodiments of Vehicle-to-everything (V2X) communications authentication are described. In some embodiments, a user equipment (UE) configured V2X communication and configured to operate within a fifth-generation system (5GS) and/or a combined 5GS and fourth-generation system (4GS) can encode a V2X capability indication in a request message for transmission to a network entity, such as a Access and Mobility Management Function (AMF). The V2X capability indication can indicate a capability of the UE for V2X communication over a PC5 reference point, and the request message can further include an indication of a Radio Access Technology (RAT). In some embodiments, the AMF can determine whether the UE is authorized to use the V2X communications over the PC5 reference point, and whether the UE is authorized to use the RAT indicated in the request message. Accordingly, the AMF can transmit a V2X services authorization to a next generation radio access network (NG-RAN).

Abstract: Some demonstrative embodiments include devices, systems and methods of communication by co-located wireless communication modules. For example, a device may be configured to receive a latency attribute indicating an allowed latency to transmit a packet using one or more shared resources shared between a plurality of wireless communication modules; receive a first priority level indicating a first transmission priority of the packet; increase the first priority level to a second priority level based on a comparison between the allowed latency and a time from reception of the latency attribute; and send the second priority level to an arbitration module, the second priority level to indicate to the arbitration module a second transmission priority to transmit the packet using the shared resources.

Abstract: An apparatus for adjusting a component in a receiver system to eliminate distortion. The apparatus may include a receiver system and a tuning circuit. The receiver system may process a tracking signal to generate an output signal. The tracking signal may include a radio frequency (RF) signal and a test signal. The processing of the first tracking signal may introduce a distortion into the output signal. The tuning circuit may be operatively coupled to the receiver system. The tuning circuit may determine an adjustment value and send the adjustment value to the receiver system. The receiver system may adjust a component of the receiver system using the adjustment value to eliminate the distortion in a second RF signal that is caused by the component.

Abstract: A user equipment (UE) can include processing circuitry configured to, during a physical random access channel (PRACH) procedure, select a first synchronization signal (SS) block from a plurality of SS blocks within a received SS burst set, the SS block selected based on signal quality measurements of the plurality of SS blocks. A PRACH preamble is encoded for transmission to a base station using a PRACH resource subset corresponding to the selected SS block, the transmission using a UE transmit (Tx) beam of a plurality of available Tx beams and transmit power indicated by a power ramping counter. Upon failing to detect a random access response (RAR) from the base station, a second SS block is selected, the power ramping counter is reset, and the PRACH preamble is encoded for re-transmission using a second PRACH resource subset and transmit power indicated by the reset power ramping counter.
