Abstract: Certain aspects of the present disclosure relate to beam selection. An example method generally includes selecting, from a plurality of beams, a beam for transmission during a particular time interval within a time window, the selecting being based on a transmission power and a radio frequency (RF) exposure for each of the plurality of beams and transmitting at least one signal using the selected beam during the particular time interval.

Abstract: A method of controlling spatial audio rendering includes comparing a first heartbeat pattern to a second heartbeat pattern to generate a comparison result. The first heartbeat pattern is based on sensor information associated with a first sensor of a first sensor type, and the second heartbeat pattern is based on sensor information associated with a second sensor of a second sensor type. The method also includes, based on the comparison result, controlling a spatial audio rendering function associated with media playback.

Abstract: Method and apparatus are provided for reporting and receiving actual UL transmission power. In accordance with some implementation, a UE may send a first indication of power headroom to a base station. The UE may receive one or more resources allocation for a UL transmission. The UE then may determine actual transmission power to be used in the UL transmission. Upon determination, the UE may transmit the UL transmission and send an indication of the actual transmission power to the base station. The base station, in response to receiving an indication of actual transmission power of the first UL transmission, may adjust an estimate of the link quality based on the receive indication of actual transmission power.

Abstract: A device includes a memory and one or more processors. The memory is configured to store instructions. The one or more processors are configured to execute the instructions to obtain electrical activity data corresponding to electrical signals from one or more electrical sources within a user's head. The one or more processors are also configured to execute the instructions to render, based on the electrical activity data, audio data to adjust a location of a sound source in a sound field during playback of the audio data.

Abstract: Certain aspects of the present disclosure provide techniques for reducing a quantity of antenna elements for uplink transmission. A method that may be performed by a user equipment (UE) includes determining a virtual power headroom (VPHR) associated with uplink transmission for each of a plurality of beams, selecting one or more beams of the plurality of beams for the uplink transmission based on the determination such that the VPHR associated with each of the one or more beams is at least equal to or greater than zero, and indicating a parameter associated with the one or more beams for selection of a beam to be used for the uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform calibration of a transceiver chain to maintain or improve operation of a device or comply with legal or protocol requirements. The UE may receive one or more wireless signals indicating a first set of resources where the first device is scheduled to transmit or receive communications. The UE may calibrate a wireless transceiver chain of the first device in a second set of resources. The second set of resources excludes the first set of resources and includes at least a portion of a third set of resources. The third set of resources are resource in which the first device has an option to transmit or receive communications based on a protocol configuration.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for selecting a PRACH occasion (RO) based on downlink quality, access congestion, latency (e.g., time to next available RO), beam correspondence, random access in previous transmissions, or combinations of these factors. The user equipment (UE) may detect access congestion of synchronization signal blocks (SSBs) and select the less congested SSB in the RO selection. The UE may detect the access congestion by receiving a back-off indicator from the base station, detecting a contention resolution failure, or the number or media access control (MAC) subheaders in a random access response. In some cases, the ROs associated with different SSBs have different latencies and the UE may select the earliest available RO.

Abstract: A method for energy-efficient state change detection and classification of streaming sequential data includes receiving via a first prediction model, sequential data from a sensor. The first prediction model determines a change in an activity state based on the sequential data. An indication that the activity state has changed is transmitted to a second prediction. The second prediction model determines an updated activity state based on the sequential data. The updated activity state is sent to the first prediction model, after which the second prediction enters an inactive state.
