Abstract: Methods and apparatus for distinguishing between an antenna of a user equipment (UE) being blocked by a cover (e.g., a protective rubber or plastic case) or by human tissue (e.g., a finger or palm). The transmission power of uplink (UL) signals may be adjusted accordingly, with relatively higher transmission power for open space or a cover and relatively lower transmission power for human tissue. One example method for wireless communications by a UE generally includes transmitting a first signal from the UE, receiving a plurality of signals at the UE based on the transmitted first signal, determining values for at least two different types of parameters based on the received plurality of signals, determining an environmental scenario for the UE based on the values for the at least two different types of parameters, and transmitting a second signal using a transmission power based on the determined environmental scenario.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal in a frequency domain, the first signal being a dual band signal that is a function of a second signal transmitted in the frequency domain, the second signal being transmitted on a same symbol or a same set of symbols as the first signal in the frequency domain, and the first signal having a lower transmission power than the second signal. The UE may perform an action based at least in part on the first signal. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices and systems for extended long range wireless packet design. Some aspects more specifically relate to increasing a data rate, a coverage range, or both for extended long range (ELR) wireless communications systems by updating an ELR wireless packet design. A wireless communications device, such as a wireless station (STA), may transmit an ELR wireless packet to another wireless communications device, such as a wireless access point (AP), with updated preamble fields, boosted transmit power for one or more preamble fields, and/or additional repetitions for one or more preamble fields. Additionally, or alternatively, the wireless communications device may transmit an ELR wireless packet using a narrow bandwidth to increase coverage range for an ELR wireless communications system.

Abstract: Apparatuses, methods, and systems are disclosed for a power spectrum density based configuration. One method includes transmitting, from a user equipment, UCI bits via a PUCCH in a shared spectrum using multiple PRBs. The method includes receiving a configuration message including a number of resource blocks for a PUCCH format 0, a PUCCH format 1, or a PUCCH format 4 depending on a SCS. The configuration message indicates at least one technique that satisfies a PUCCH PSD requirement, and the PUCCH PSD requirement includes a larger sequence length generation, mapping information that maps time and frequency domain resources for larger sequence to multiple RBs or a repetition of sequences to multiple RBs, and/or information corresponding to subcarrier interlacing.

Abstract: Methods, systems, and devices for wireless communications are described. Multiple component carriers may be configured for communications between communication devices, where uplink data channel resources may be scheduled on a component carrier of the component carriers. A communication device may report, over the uplink data channel resources to another communication device, a first report for available transmission power for uplink data transmissions over the component carrier and a second report associated with available transmission power for uplink control transmissions over a second component carrier. The other communication device may use the second report to determine the available transmission power for uplink control transmissions over the second component carrier. The other communication device may schedule communication resources based on the determined available transmission power for uplink control transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. A method at a user equipment (UE) includes receiving signaling that indicates a carrier aggregation (CA) configuration (having carriers configured for UL and downlink (DL) data transmissions) and an auxiliary uplink (UL) configuration (having carriers configured for UL reference signal transmissions). The method also includes receiving a resource assignment on a DL carrier of the CA configuration, and transmitting an aperiodic sounding reference signal (A-SRS) using the one or more carriers of the auxiliary UL configuration based at least in part on the received resource assignment. Another method is performed by a UE having a CA configuration and an A-SRS configuration, including receiving a resource assignment on a DL carrier in the CA configuration, detecting a trigger for transmitting an A-SRS, determining UL resources of the A-SRS configuration for transmitting the A-SRS, and transmitting the A-SRS on the determined UL resources.
