Abstract: Techniques and devices for wireless communication are described. A communication device may identify a set of beam level selection parameters. The set of beam level selection parameters may include traffic information, channel information, application information, or any combination thereof. The communication device may select, based on the identified set of beam level selection parameters, a beam level, from a set of beam levels, different from a baseline beam level associated with the wireless communication. The selected beam level may be associated with a number of antenna elements different from a number of antenna elements associated with the baseline beam level. The communication device may perform the wireless communication based on the selected beam level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may determine a time-averaged power limit of a set of antennas. The apparatus may modify an antenna switching configuration based at least in part on the time-averaged power limit. The apparatus may transmit a signal using an antenna, from the set of antennas, associated with the modified antenna switching configuration, wherein the antenna is associated with a higher power limit than one or more other antennas. Numerous other aspects are described.

Abstract: Aspects relate to a calibration of an antenna array module of a wireless communication device in open space. The antenna array module may be used as a proximity sensor to detect an object's proximity relative to the antenna array module. Aspects include displaying an open space calibration instruction on a display of the wireless communication device, transmitting a proximity test signal from the antenna array module, measuring a value of a first signal received at the antenna array module in response to transmitting the proximity test signal, and storing the value of the first signal as an open space calibration value of the antenna array module. The first signal may be measured at cross-polarized antennas of the antenna array module. The value of the first signal may be representative of perturbations of the proximity test signal at the cross-polarized antennas.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a broadcast or multicast (broadcast/multicast) application associated with a first radio access technology (RAT) while the UE is in a standalone mode for a second RAT; switch from the second RAT to the first RAT based at least in part on initiating the broadcast/multicast application; and switch from the first RAT to the second RAT based at least in part on failing to detect a communication associated with the broadcast/multicast application using the first RAT. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may receive an indication of a traffic pattern for application traffic. The BS may determine, based at least in part on one or more measurements associated with the traffic pattern, one or more parameters for at least one of a discontinuous reception (DRX) configuration for the application traffic, or a semipersistent scheduling (SPS) configuration for the application traffic. The BS may transmit, to a user equipment (UE) that is to receive the application traffic, an indication of the at least one of the DRX configuration or the SPS configuration. Numerous other aspects are provided.

Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Aspects of the present disclosure provide a simplified solution for proximity detection of an object in a wireless communication that does not require complex hardware to maintain mutual coupling reference signal. Specifically, in accordance with aspects of the present disclosure, the received signal that may include the mutual coupling signal and target signal may be multiplied by itself to extract the delay information associated with the target signal. The techniques outlined here may provide a greater robustness to variations of mutual coupling induced by phone covers, for example, being added by the user.

Abstract: A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.

Abstract: A user equipment (UE) may communicate over a first wireless wide area network (WWAN). The first WWAN may be supported by a first subscriber identity module (SIM) of the UE. The UE may also communicate simultaneously over a second WWAN supported by a second SIM. The UE may process the second WWAN communication with a portion of a WWAN module and a portion of a wireless local area network (WLAN) module.
