Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to determine whether to maintain or remove a radio frequency (RF) path from a set of candidate paths considered for transmit antenna switch diversity (ASDIV). The determination allows the UE to avoid signal loss or degradation in coexisting networks at similar frequency ranges. For example, ASDIV allows two or more antennas to form different input and output ports to establish different RF paths. Coexistent networks, such as wireless wide-area-network (WWAN) and wireless local-area-network (WLAN) may utilize different RF paths to optimize reliability and efficiency. The overlapping of the bands may cause signal attenuation or degradation from at least one of the networks. The present disclosure provides techniques for detecting signal attenuation at least partially caused by overlapping bands and removing an associated RF path to avoid such signal loss or attenuation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A wireless communication device may have an apparatus that aligns the non-linearity between transmit chains of the wireless communication device that are driven by the same digital port. The apparatus may adjust an amplification power out or an amplification saturated power to adjust a ratio between the amplification saturated power and the amplification power out for one or more transmit chains of the wireless communication device. The apparatus may adjust the ratios of transmit chains to align the ratios of the transmit chains for more consistent management of non-linear characteristics of the chain components. Numerous other aspects are described.

Abstract: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first transmit power limit based at least in part on at least one of a specific absorption rate limit, a maximum permissible exposure limit, or a power density limit. The UE may modify, based at least in part on a scaling factor associated with a time interval, the first transmit power limit to obtain a modified first transmit power limit. The UE may transmit a signal based at least in part on the modified first transmit power limit. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support dynamic clock switching within a transmission time interval (TTI) to allow for more efficient and flexible processing within the TTI. In particular, a user equipment (UE) may be configured to use multiple clock speeds for processing signals within a TTI, and the UE may determine a clock speed to use for processing data within a TTI based on control information received from a base station. For example, the UE may determine an amount of time available for processing data based on the control information received from the base station, and the UE may adjust its clock speed to finish processing the data in the determined amount of time.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support adaptation of digital pre-distortion (DPD) coefficients based on a temperature of a user equipment (UE). The UE may determine a power offset value based on a first temperature value associated with a training procedure for the UE, a second temperature value associated with the UE, and a constant value. The training procedure may be associated with multiple sets of coefficients for the UE. The UE may apply the power offset value to a transmission power level for transmission of a message. The UE may determine a set of coefficients of the multiple sets of coefficients based on the training procedure and the power offset value applied to the transmission power level. The UE may apply the coefficients to a DPD engine of the UE to generate the message for transmission at the transmission power level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a first set of throughput targets and a second set of throughput targets for an application layer. The UE may set a target throughput rate associated with the application to a required throughput target included in the first set of throughput targets. The UE may monitor a real-time throughput rate associated with the application layer. The UE may set the target throughput rate to a value in the second set of throughput targets based at least in part on a difference between the real-time throughput rate and the required throughput target satisfying a threshold. The UE may select, from a set of candidate beams, a serving beam associated with an estimated application layer throughput that satisfies the target throughput rate. Numerous other aspects are described.
