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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate via a first connection using one or more transmit parameters. The UE may determine to suspend subsequent attempts to communicate via a second connection, in a dual connection mode, based at least in part on satisfaction of a threshold number of failed attempts to communicate via the second connection. The UE may determine one or more parameters for suspension of the subsequent attempts to communicate via the second connection based at least in part on a determination that satisfaction of the threshold number of failed attempts is associated with one or more exposure conditions that are based at least in part on the one or more transmit parameters. Numerous other aspects are provided.

Abstract: Auto-recovery from RF signal acquisition failure may be provided in a portable computing device. A field-calculated frequency-temperature (“FT”) curve is used to apply temperature compensation to a crystal oscillator associated with RF transceiver circuity of the device. In response to acquisition failure, it may be determined whether a deviation between the field-calculated FT curve and a factory-set FT curve exceeds threshold criteria. In response to acquisition success, the field-calculated FT curve may be refined based on frequency error information. However, in response to acquisition failure and a determination that the deviation exceeds the threshold criteria, information defining the field-calculated FT curve may be replaced with information defining the factory-set FT curve.

Abstract: Certain aspects of the present disclosure provide techniques for operating a wireless communication device pursuant to radio frequency (RF) exposure with antenna grouping. An example method of wireless communication by a user equipment generally includes accessing a stored backoff factor associated with an antenna group among a plurality of antenna groups. The method also includes transmitting, from at least one transmit antenna in the antenna group, a signal at a transmission power level based on the backoff factor in compliance with an RF exposure requirement.

Abstract: Techniques and apparatus for configurable radio frequency (RF) exposure compliance based on region. An example method of wireless communication by a user equipment (UE) generally includes identifying a region in which the UE is located, selecting at least one of a mode or one or more parameters for RF exposure compliance based on the identified region, and transmitting a signal at a transmission power level based at least in part on the at least one of the selected mode or the selected one or more parameters.

Abstract: Certain aspects of the present disclosure provide techniques for exception-robust time-averaged radio frequency (RF) exposure compliance continuity. A method that may be performed by a user equipment (UE) generally includes transmitting a first signal at a first transmission power based on time-averaged RF exposure measurements over a time window and storing RF exposure information associated with the time window. The method may also include detecting that an exception event associated with the UE occurred and transmitting a second signal at a second transmission power based at least in part on the stored RF exposure information in response to the detection of the event.

Abstract: Various examples include methods for assisting Global Positioning System (GPS) applications using a Long Term Evolution (LTE) subscription on a wireless communication device. Various example methods may include determining whether positioning information can be obtained from a first network associated with the LTE subscription, obtaining the positioning information from the first network through the LTE subscription in response to determining that the positioning information can be obtained from the first network, translating the positioning information into a format recognizable to a GPS application executing on the wireless communication device, and providing the positioning information to the GPS application.
