Abstract: This disclosure provides systems, methods, and apparatuses for adjusting an encoding timing or a decoding timing in a manner that minimizes disruption of ongoing uplink or downlink traffic. Some aspects more specifically relate to decoupling adjustment of the encoding timing and adjustment the decoding timing to enable independent adjustment of the encoding timing or the decoding timing. In some aspects, a user equipment (UE) may perform adjustment of the encoding timing, relative to an active time indicated by a discontinuous reception (DRX) configuration, at a time at which uplink traffic is absent. Additionally, or alternatively, the UE may perform adjustment of the decoding timing, relative to an active time indicated by a DRX configuration, at a time at which downlink traffic is absent. Accordingly, upon receiving a DRX configuration, the UE may wait until a period in which uplink traffic or downlink traffic is absent to perform a timing adjustment.

Abstract: A Precise Point Positioning (PPP) system is disclosed in which one or more Global Navigation Satellite System (GNSS) signals are obtained by a mobile device. The mobile device can obtain position information based on one or more position sources, where the position information is indicative of a location of the mobile device. One or more PPP positions of the mobile device can be determined based on the position information and the one or more GNSS signals, where a position uncertainty of the position information meets or is below an uncertainty threshold. A determination of whether at least one PPP position meets or is below one or more convergence thresholds can be made. In response to determining that at least one PPP position meets or is below the one or more convergence thresholds, the at least one PPP position can be provided.

Abstract: Disclosed are various techniques for wireless communication. In one aspect, a user equipment (UE) may receive, from a satellite vehicle (SV), a signal of a first frequency band, estimate a first ionospheric delay residual error based on the signal of the first frequency band, calculate a first pseudorange measurement and a first carrier phase measurement based on the first ionospheric delay residual error, and estimate a position using the first pseudorange measurement and the first carrier phase measurement. In some aspects, the ionospheric delay residual error is estimated via a Klobuchar equation. In some aspects, the position is estimated using ultra-long baseline real-time kinematics (RTK) positioning.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part a determination to transmit one or more packets, a scheduling request (SR) occasion in which to transmit an SR for uplink resources to transmit the one or more packets, the SR occasion occurring prior to a start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR occasion occurs within a threshold amount of time prior to the start of the CDRX on duration of the UE. The UE may transmit the SR in the SR occasion based at least in part on the determination of whether the SR occasion occurs within the threshold amount of time prior to the start of the CDRX on duration of the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for an enhanced query and response message for a recommended bit rate for uplink and/or downlink streaming. The techniques generally include generating a query message indicating a requested data rate for streaming services, wherein the requested data rate is indicated via a bit rate field and one or more additional bits, and sending the query message to a base station.

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: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

Abstract: The disclosure generally relates to various methods to increase network coverage with respect to Voice-over-Internet Protocol (VoIP) sessions and/or other voice-based multimedia services. In particular, when establishing a voice session, two or more terminals may perform a codec negotiation to exchange information related to supported multimedia codecs and/or codec modes, jitter buffer management (JBM), and packet loss concealment (PLC) capabilities. Based on the exchanged information, a message may be sent to a base station to indicate the maximum packet loss rate (PLR) for each terminal. Additional techniques may ensure that the terminals use the most robust codecs or codec modes that are available when nearing the edge of coverage to help avoid unnecessary and/or excessive handovers to different radio access technologies.

Abstract: Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a "wall clock," recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.

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.
