    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: Multiple base stations, which may be controlled by different network operators, share a transmission medium to serve multiple user equipment (UE). A first base station determines that the shared communication medium is free. The first base station transmits, during a first medium access slot on the shared communication medium, a pre-grant for a first UE associated with the first base station. The first UE transmits a response message during the first medium access slot. Optionally, a second base station may join the transmission by transmitting a pre-grant to a second UE during a subsequent medium access slot.

    Abstract: A network operator may synchronize access for wireless nodes (e.g., base stations) associated with the network operator. However, each network operator of a group of network operators may not synchronize access among the group. A lack of synchronization between network operators intending to utilize shared channels of a wireless communication system may result in a failure to utilize all available network resources. In some aspects, a device associated with a first network operator, of a plurality of network operators, may listen for communications associated with other network operators, of the plurality of network operators in a shared radio frequency spectrum band, during a set of intervals of a transmission opportunity of a channel for which the other network operators have a higher priority, and may communicate, using the channel, with a wireless node associated with the network operator based at least in part on the listening for communications.
