Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a capability message indicating a capability supporting network-side phase noise compensation. The UE may transmit, to the base station, phase tracking reference signals based on transmitting the capability message. In an example, the phase tracking reference signals may include a UE phase noise component which may be associated with a local oscillator of the UE. The UE may receive, from the base station, a compensated downlink transmission that is compensated based on the UE phase noise component. In generating the compensated downlink transmission, the base station may apply a multiplication factor associated with the estimated UE phase noise component to the compensated downlink transmission.

Abstract: A device generates an estimated size of encoded versions of one or more pictures of video data prior to generating the encoded versions of the one or more pictures. A physical layer of a radio system of the device is configured to send a message to a wireless base station. The message indicates a size value based on the estimated size of the encoded versions of the one or more pictures. The physical layer of the radio system receives an uplink grant notification in response to the message. Based on the uplink grant notification, the physical layer of the radio system sends packets to the wireless base station containing the encoded versions of the one or more pictures.

Abstract: Methods, systems, and devices for wireless communications are described. Beam management procedures may increase communications quality and reliability in wireless networks that support narrow directional beams and high frequencies. Some such beam management procedures utilize continuous beam measurements and adaptive beam switching to maintain a threshold link level between devices. A user equipment (UE) may transmit an indication of a capability to perform a first beam refinement procedure in response to a data transmission and using multiple receive beams. The UE may select a communication beam using a first instance of a second beam refinement procedure, and may receive a data transmission from a base station using the selected beam. Based on receiving the data transmission, the UE may perform the first beam refinement procedure and may skip a second instance of the second beam refinement procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a beam quality metric associated with a reference signal for each candidate beam of a plurality of candidate beams. The UE may determine a set of channel characteristics for each candidate beam of the plurality of candidate beams, where the set of channel characteristics indicates to the UE a level of channel equalization by the UE associated with processing signaling on each candidate beam of the plurality of candidate beams. In some cases, the set of channel characteristics may include a frequency selectiveness of a channel for each candidate beam of the plurality of candidate beams. The UE may select a candidate beam from the plurality of candidate beams based on the beam quality metric and the set of channel characteristics and communicate with a base station using the selected candidate beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive multiple spatial dimension multiplexed (SDM) communications via a single antenna panel of the UE. The UE may perform phase noise correction for the multiple SDM communications based at least in part on phase tracking reference signals received via a single communication of the multiple SDM communications. Numerous other aspects are provided.

Abstract: Coherence based pre-decoding pruning for control channels in wireless communication systems is discussed. Data is received on at least one channel resource of a plurality of channel resources. In addition, the determining of a plurality of channel coherence metrics is discussed, where a channel coherence metric for a channel resource indicates coherence information between channels on which the plurality of carriers associated with the channel resource operate. Additionally, the determining of one or more channel resources to search for data to be decoded based, at least in part, on the plurality of channel coherence metrics is also discussed. Other aspects, embodiments, and features are also claimed and described.
