Abstract: Aspects described herein include devices and methods for facilitating digital predistortion calibration. One aspect includes selecting a first transmission element from a plurality of transmission elements associated with a first antenna element of a plurality of antenna elements in an antenna array of the millimeter wave communication device, wherein the first transmission element is selected based on a gain setting for the first transmission element, selecting a reference transmission power for a test transmission from the first transmission element as part of a path searching operation of the millimeter wave communication device, determining a selected receive element of the plurality of receive elements based on a near field power measurement of the reference transmission power from the first transmission element using the selected receive element and a set of selection criteria, and setting a digital predistortion calibration setting using the reference transmission power and the near field power measurement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may apply a crest factor reduction (CFR) to an input signal to generate an output signal, the applying the CFR to the input signal including applying a shaping filter that distributes a first portion of CFR noise within a transmission frequency band of the output signal and a second portion of the CFR noise in at least one air interface resource that is outside of the transmission frequency band of the output signal. The network node may transmit the output signal. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE measures the power of a transmission channel for communication between the UE and a network entity during a predetermined time window via a power detector of the UE. Based on the power of the transmission channel, the UE monitors for a wake-up signal (WUS) using a wake-up radio (WUR) or a main radio (MR). The WUS may or may not include a preamble. If the WUS includes a preamble, the UE monitors for the WUS based on the preamble. The method enables a UE to sense the power level associated with a WUS using a power detector, and use a radio that adapts better to the perceived power level (e.g., the WUR or the MR) to monitor for the WUS. Hence, it improves the power consumption efficiency of wireless communication.

Abstract: A network node may transmit a signal for a controller associated with at least one RIS/repeater, the signal including a TCI state associated with at least one backhaul channel between the network node and at least one repeater, and obtain a measurement of a reference signal of the at least one backhaul channel based on the signal including the TCI state associated with the at least one backhaul channel. The controller and the at least one RIS/repeater may indicate the measurement of reference signal of the at least one backhaul channel based on the signal including the TCI state associated with the at least one backhaul channel.

Abstract: Certain aspects are directed to an apparatus configured for wireless communication. The apparatus may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the one or more processors are configured to cause the apparatus to obtain a sample of an analog signal. In some examples, the one or more processors are configured to cause the apparatus to output the sample to an analog-to-digital converter (ADC) via one of at least a first path or a second path based at least in part on whether the sample satisfies a first threshold condition or a second threshold condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a first resource within a slot and a second resource within the slot. The UE may receive a demodulation reference signal (DMRS) based at least in part on the first resource, wherein the DMRS is associated with a first transmit power. The UE may receive an additional DMRS based at least in part on the second resource, wherein the additional DMRS is associated with a second transmit power different from the first transmit power.

Abstract: A network device is provided with excessive interference mitigation. In one implementation, the network device transmits a notification of the excessive interference to a network entity. In another implementation, the network device changes a receive beam or begins to acquire a new cell in response to a detection of the excessive interference. In yet another implementation, the network device alerts a user in response to a detection of the excessive interference.
