Abstract: Various embodiments may employ neural networks at transmitting devices to compress transmit (TX) waveform distortion. In various embodiments, compressed TX waveform distortion information may be conveyed to a receiving device. In various embodiments, the signaling of TX waveform distortion information from a transmitting device to a receiving device may enable a receiving device to mitigate waveform distortion in a transmit waveform received from the transmitting device. Various embodiments include systems and methods of wireless communication by transmitting a waveform to a receiving device performed by a processor of a transmitting device. Various embodiments include systems and methods of wireless communication by receiving a waveform from a transmitting device performed by a processor of a receiving device.

Abstract: A method of wireless communication performed by a receiving device includes determining a transmission reference point value and determining a transmission reference point gradient of a loss based on the transmission reference point value. The receiving device also transmits a message comprising the transmission reference point gradient to a transmitting device. A method of wireless communication by a transmitting device includes receiving a transmission reference point gradient of a loss from a receiving device. The transmitting device determines a transmission point-payload gradient of a transmission reference point value with respect to an encoded value generated by a transmitter neural network. The transmitting device also determines a payload gradient of the loss based on a product of the transmission reference point gradient and the transmission point-payload gradient. The transmitting device further updates weights of the transmitter neural network based on the payload gradient.

Abstract: Aspects of the present disclosure disclose techniques for the indication of the allocation of the downlink (DL) demodulation reference signal (DM-RS) ports for the data channel in NR communications. In some examples, the channel state information (CSI) reference signal (CSI-RS) may be associated with a corresponding DM-RS for a DL data channel. The transmitting device, in some examples, may further transmit a notification that provides resource allocations (e.g., port allocations) that minimize the redundant information that is required to be transmitted from the base station to the user equipment (UE) when the DM-RS port allocation is the same as the CSI-RS port allocation received by the UE in an earlier time slot.

Abstract: Aspects of the present disclosure describe activating a high speed train (HST) configuration for communicating with a cell in a HST based communications environment. A first signal including an HST activate indication to activate a HST configuration can be received from a cell. The HST configuration can be activated based at least in part on the HST activate indication. One or more subsequent signals can be communicated with the cell using the HST configuration based at least in part on the HST activate indication.

Abstract: Aspects of the present disclosure describe discovering physical cell identifiers in wireless communications. It can be determined to discover a physical cell identifier of one or more cells in a zone based at least in part on detecting a condition. A cell-specific signal can be received from at least one cell of the one or more cells in the zone. The cell-specific signal can be associated with one of a plurality of cell-specific signal hypotheses. The physical cell identifier of the at least one cell can be determined as one of a plurality of physical cell identifiers that corresponds to the one of the plurality of cell-specific signal hypotheses.
