Certain aspects of the present disclosure provide techniques wireless communication at a first wireless node generally including communicating with a second wireless device using a first beam, detecting at least one condition indicative of receiver saturation at the first wireless device or the second wireless device, and taking at least one action designed to mitigate the receiver saturation after detecting the at least one condition.

Mitigation of receiver saturation via beam adjustment

In some implementations, a mobile device may determine a set of target orientations of the mobile device in which an antenna lobe of the mobile device is pointed toward the satellite, the set of target orientations based on: an orientation of the antenna lobe relative to the mobile device, and a location of the satellite relative to the mobile device. The mobile device may determine a current orientation of the mobile device. The mobile device may provide, at a user interface (UI) of the mobile device, guidance for rotating the mobile device from the current orientation to an orientation within the set of target orientations.

Mobile device orientation guidance for satellite-based communications

In certain aspects, a method implemented in a wireless device includes determining a specific absorption rate (SAR) distribution for a first wireless communication technology, determining a power density (PD) distribution for a second wireless communication technology, and combining the SAR distribution and the PD distribution to generate a combined RF exposure distribution. The method also includes determining at least one first maximum allowable power level and at least one second maximum allowable power level for a future time slot based on the combined RF exposure distribution, setting at least one transmission power limit for a first transmitter in the future time slot based on the at least one first maximum allowable power level, and setting at least one transmission power limit for a second transmitter in the future time slot based on the at least one second maximum allowable power level.

Evaluating radio frequency (RF) exposure in real time

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.

Resource selection for random access

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain configurations, the apparatus may be a user equipment (UE). The apparatus may receive configuration information for UL and DL transmissions from another device such as a base station. The apparatus may determine a maximum duty cycle of the UL transmission based on the configuration information. Based on the determined UL maximum duty cycle, the apparatus may determine a transmit power limit for the UL transmission. In one aspect, the apparatus may determine the UL transmit power limit by dividing the power corresponding to a maximum permissible exposure (MPE) limit by the determined maximum UL duty cycle. The apparatus may leverage the forward knowledge of the UL duty cycle to transmit at a power level that complies with the MPE limit while avoiding the poor uplink range associated with static power back-off.

Methods for maximum permissible exposure mitigation based on new radio time domain duplex configuration

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.

Persistent two-stage activity recognition

Methods and systems for determining transmission power levels according to signal types and RF exposure limits. An example method generally includes determining a first transmission power for transmitting a first type of uplink (UL) signal, determining a second transmission power for transmitting a second type of UL signal based on the first transmission power, and transmitting at least one of the first UL signal according to the first transmission power or the second UL signal according to the second transmission power.

Power limits based on signal type for managing maximum permissible exposure

Systems and techniques are described herein. For example, a process can include obtaining first sensor measurement data associated with a and second sensor measurement from one or more sensors. In some cases, the first measurement data can be associated with a first time and the second sensor measurement data can be associated with a second time occurring after the first time. In some aspects, the process includes determining that the first sensor measurement data and the second sensor measurement data satisfy at least one batching condition. In some examples, the process includes, based on determining that the first sensor measurement data and the second sensor measurement data satisfy the at least one batching condition, generating a sensor measurement data batch including the first sensor measurement data, the second sensor measurement data, and at least one target sensor measurement data. Ins examples the process includes outputting the sensor measurement data batch.

Sensor calibration

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.

Beam selection balancing maximum power exposure and link budget

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.

Audio adjustment based on user electrical signals

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.

Reducing number of antenna elements for uplink transmission

Methods, systems, and devices for wireless communications are described. Generally, Generally, a base station may send to a user equipment (UE) a configuration message, which may include an indication of one or more CSI-RS resources and one or more random access occasion indices. The UE may identify one or more random access occasions associated with the UE based on the CSI-RS resources, the random access occasion indices for the UE, and a random access occasion index reset time. The random access occasion index rest time may be based on a fixed time period. The random access occasion index reset time may be based on a number of CSI-RS resources. In some examples, the random access occasion index reset time may be based on a number of actually transmitted synchronization signal blocks (SSBs).

Indexing of random access occasions for channel state information reference signal based random access procedures

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.
