Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a distributed leaky bucket based scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on the determined delivery delays. In various embodiments, delivery delays may be determined based on leaky bucket levels, burst sizes, delivery rates, and end to end delay estimates for each of the plurality of modems. In various embodiments, the scheduler may be one of a plurality of schedulers each associated with a separate stream of packets assigned to the plurality of modems and the leaky bucket levels may be determined on a per stream basis.

Abstract: Systems, methods, and devices of the various embodiments provide for header extension preservation, security, authentication, and/or protocol translation for Multipath Real-Time Transport Protocol (MPRTP). Various embodiments include methods that may be implemented in a processor of a computing device for MPRTP transmission of Real-Time Transport Protocol (RTP) packets. Various embodiments may include receiving an RTP packet in which the received RTP packet may be part of an RTP stream that may be protected using secure RTP (SRTP), and applying an authentication signature to the RTP packet to authenticate an MPRTP header extension separate from a body of the RTP packet. Various embodiments may include sending and/or receiving MPRTP subflows of an MPRTP session in which a same security context may be applied across all MPRTP subflows of the MPRTP session.

Abstract: Disclosed are methods and apparatus for improving the performance of a user equipment handover during a data call. In one aspect, a source base station determines to handover user equipment (UE) to a target base station. The source base station first determines whether the UE is in a data call prior to the handover. The source base station then modifies one or more of connected mode discontinuous reception (CDRX) and semi-persistent scheduling (SPS) parameters with the UE based on determining to handover the UE and determining that the UE is in the data call.
