Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, prior to expiration of a barred cell timer that is associated with a barred cell, a measurement configuration that indicates to measure a frequency that is associated with the barred cell. The UE may compute that a signal metric associated with the frequency and the barred cell satisfies a quality threshold. The UE may selectively refrain from transmitting the signal metric based at least in part on a state of the barred cell timer. Numerous other aspects are described.

Abstract: During positioning of a user equipment (UE), downlink (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE by a serving TRP identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain downlink positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may comprise a transceiver configured to transmit uplink frames and receive downlink frames in a first transaction slot of a super-frame. The one or more of the uplink frames and the downlink frames are associated with over-allocated network allocation vectors that reserve a transmission time which exceeds a time required to transmit acknowledgements of the one or more downlink frames or receive acknowledgement of the one or more uplink frames, respectively. The apparatus may comprise a processing system configured to cause the transceiver to transmit a first uplink frame to the access point with a first over-allocated NAV, to establish a start-time for the super-frame and to extract data from two or more downlink frames in a burst received from the access point.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for efficiently indicating transmission configuration indication (TCI) states to a user equipment (UE) for communicating with one or more transmission and reception points (TRPs). A first TRP may transmit an indication to a UE of a first TCI state for communicating with a second TRP. The first TCI state may be selected from a set of TCI states activated at the UE for communicating with the second TRP. The indication, from the first TRP, of the first TCI state, for communicating with the second TRP, may be referred to as a cross-TRP TCI indication. The UE may receive the indication of the first TCI state from the first TRP and may communicate with the second TRP according to the first TCI state.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a network access device may include receiving a random access preamble; identifying a quantity of uplink grants to associate with the random access preamble, the identified quantity of uplink grants including at least one uplink grant associated with at least one transmission resource, the identified quantity of uplink grants based at least in part on a time-variable parameter; and transmitting a random access response message including the identified quantity of uplink grants.

Abstract: Methods, systems, and devices for wireless communication are described. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.

Abstract: Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media to improve the calibration data by taking into account the effects of change in temperature on motion sensors. For instance, different levels of error may be associated with a motion sensor at different temperature levels. In one implementation, the sensor measurement data associated with the various orientations at a temperature is used in determining the calibration data for that temperature.

Abstract: In an embodiment, a user equipment (UE) determines to originate a communication session, and the UE further determines whether an access network serving the UE supports header compression. Based on the header compression determination, the UE establishes on a given bundling factor (BF). The UE transmits a first set of media packets to a server during the communication session, the first set of media packets each including a first number of media frames based on the given BF. The server determines target BF(s) for target UE(s) and determines whether to modify the given BF based on the target BF(s). Based on these determinations, the server transmits a second set of media packets either unmodified from the first stream of data packets, or modified based on the target BF(s). The target UE(s) receive the second stream of data packets and set a de-jitter buffer size based on the associated BF.
