Abstract: Systems and methods for providing indications about the TX RF non-linear impairments are disclosed. In accordance with some implementations, a first device (UE or base station) estimates EVM indications for the signal and determines if the EVM indications is above a threshold. The first device may transmit the estimated TX non-linearity indications such as AM-AM, AM-PM, Volterra coefficients, and/or other performance metrics to a second device, that transmitted the signal, when it is determined that the EVM indications is above the threshold. Systems and methods for wireless communication impairment correction are also disclosed wherein, in accordance with some implementations, a first device receives estimated TX non-linearity indications such as AM-AM, AM-PM, and/or Volterra coefficients from a second device and performs non-linear correction of a transmit signal for the second receiver device based at least in part on the EVM indications. Other aspects, embodiments, and features are also claimed and described.

Abstract: A transmitter may be configured to generate a reference signal having a non-constant envelope for nonlinearity estimation by a receiver. The transmitter may transmit the reference signal. A receiver may be configured to receive, from the transmitter, the reference signal having the non-constant envelope. The receiver may estimate at least one nonlinearity characteristic based on the reference signal having the non-constant envelope. The receiver may transmit feedback based on the at least one nonlinearity characteristic and/or perform at least one digital post distortion (DPoD) operation based on the at least one nonlinearity characteristic.

Abstract: Apparatus, methods, and computer program products for full-duplex (FD) communications are provided. An example method may include transmitting, during a time interval, a first transmission on a plurality of transmission (TX) subcarriers corresponding to a first TX component carrier (CC). The example method may further include receiving, during the time interval, a second transmission on a set of reception (RX) subcarriers corresponding to one or more RX CCs, where the set of RX subcarriers includes a respective plurality of RX subcarriers corresponding to each RX CC of the one or more RX CCs, and where the plurality of TX subcarriers and the set of RX subcarriers are interleaved in frequency such that the plurality of TX subcarriers is periodical in frequency and the set of RX subcarriers is periodical or non-periodical in frequency.

Abstract: Certain aspects of the present disclosure provide techniques for analog front end (AFE) non-linear model estimation. An example method includes transmitting a first message including a request for a second wireless communications device to transmit a signal to the first wireless communications device, receiving, from the second wireless communications device, the signal based on the first message, determining a non-linear model of an AFE of the first wireless communications device based on the signal received from the second wireless communications device, and taking one or more actions based on the determined non-linear model of the AFE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a counter value and a correlation threshold parameter associated with a wake-up signal for tracking (WUT) to be received by a wake-up receiver (WUR) of the UE. The UE may count WUR failure occurrences based at least in part on the correlation threshold parameter. The UE may initiate a beam recovery process in accordance with a quantity of WUR failure occurrences being greater than or equal to the counter value. In some aspects, the UE may receive an indication of a set of transmission configuration indication (TCI) states to be monitored. The UE may monitor, for each TCI state of the set of TCI states, a wake-up signal for tracking (WUT) using a wake-up receiver (WUR) of the UE. Numerous other aspects are described.

Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.
