Abstract: A wireless network may include a PCELL base station, an SCELL base station, and user equipment (UE) that communicate using standalone carrier aggregation. The UE may receive PCELL signals during first measurement periods, may perform first measurements on the PCELL signals, may receive SCELL signals during second measurement periods, and may perform second measurements on the SCELL signals. When a scheduled reporting time approaches, the UE may compare a duration between a most recent of the second measurement periods and the reporting time to a threshold. If the duration is less than the threshold, the UE may include the most recent second measurement in a measurement report transmitted at the scheduled reporting time. When the duration exceeds the threshold, the receiver may perform a third measurement on the SCELL signals during an unscheduled period prior to the reporting time and may include the third measurement in the measurement report.

Abstract: Methods, systems, apparatuses, and computer programs for transmission of a radio resource control (RRC) reconfiguration complete message are disclosed. In one aspect, operations are performed by a UE and can include receiving, from a base station, a first downlink control information (DCI) indicating a first uplink grant for a first physical uplink shared channel (PUSCH) transmission, wherein the first DCI includes a redundancy version (RV) corresponding to the first PUSCH transmission; determining whether the RV is self-decodable; and determining whether to transmit a RRC reconfiguration complete message using the first uplink grant for the first PUSCH transmission, based at least in part on the determination of whether the RV is self-decodable.

Abstract: A terminal may include configured to receive, from a network, multiple downlink signals. The terminal may include a processor configured to identify, from the downlink signals, at least one configuration parameter including a bandwidth part switching indicator. The processor may then identify at least one resource from a target bandwidth part indicated by the bandwidth part switching indicator. The processor may then determine a bandwidth part mismatch based on whether a signal is received using the at least one resource from the target bandwidth part.

Abstract: Systems, methods, and apparatuses disclosed herein can mitigate transmitting latency to improve the quality of a voice or the video call. These systems, methods, and apparatuses reset a transmitting latency timer upon retrieving a packet from a transmitting buffer. Thereafter, these systems, methods, and apparatuses start the count of the transmitting latency timer as the packet is being processed. And these systems, methods, and apparatuses compare the transmitting latency timer e with a transmitting latency threshold as these systems, methods, and apparatuses are processing a packet for transmission. These systems, methods, and apparatuses can drop the packet and/or can select another packet for processing in response to the transmitting latency timer exceeding the transmitting latency threshold to mitigate the transmitting latency.

Abstract: Techniques for low power voice communications include determining a time between an arrival of data for uplink transmission by a device and a scheduling request (SR) occasion, the SR occasion occurring after the arrival of the data and within an on duration of a discontinuous reception (DRX) cycle, and delaying transmission of a SR by the device during a time period that begins at the arrival of the data for uplink transmission and continues for the determined time.

Abstract: The techniques provide solutions for a user equipment (UE) and base station to switch between T1R4 and 2T4R for sounding reference signals (SRS). The UE and base station may communicate SRS using 2T4R. The UE and/or base station may detect and evaluate a signal quality trigger and/or condition relating to switching from T2R4 to T1R4. The trigger and/or condition may correspond to a channel or radio frequency (RF) quality, conflicting or problematic band combinations used in a non-standalone (NSA) scenario, whether dedicated data subscription (DDS) subscriber identity module (SIM) or non-DDS SIM is being used in a dual SIM dual active (DSDA) scenario, etc. The UE and base station may either continue using T2R4 communications or switch to T1R4 communications based on the trigger and/or evaluation.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a slot allocation information from a network device. The slot allocation information indicates a first slot and a second slot. The first slot is configured to communicate voice traffic and the second slot is configured to communicate traffic other than voice. The UE communicates the voice traffic in the first slot and the traffic other than voice in the second slot.
