    Abstract: Various embodiments include methods performed in receiver circuitry of a wireless communication device for demodulating wireless transmission waveforms to reconstruct data tones, which may include receiving, from a transmitter, wireless transmission waveforms that includes peak reduction tones (PRTs) that were inserted by a PRT neural network in the transmitter, and demodulating the received wireless transmission waveforms using a decoder neural network that has been trained based on outputs of the transmitter to output a reconstruction of the data tones. Further embodiments include exchanging information between the transmitter and receiver circuitry to coordinate the PRT neural network used for inserting PRTs in the transmitting wireless communication device and the decoder neural network used in the receiving wireless communication device for demodulating transmission waveforms received from the transmitting wireless communication device.

    Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than (4) receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to (8). As another example, the number of RX antenna ports may be equal to (6). The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.

    Abstract: Aspects directed towards enhancing channel quality indicator (CQI) feedback are disclosed. In one example, a determination is made of a first CQI associated with a first transmission layer and a second CQI associated with a second transmission layer. At least one delta CQI is ascertained, which is a ratio of the second CQI and first CQI. A channel state information (CSI) report that includes the at least one delta CQI is then transmitted on an uplink channel. In another example, a user equipment (UE) is configured to determine a first CQI associated with a first transmission layer and a second CQI associated with a second transmission layer. The UE is instructed to ascertain at least one delta CQI, which is a ratio of the second CQI and first CQI. A CSI report that includes the at least one delta CQI is then received from the UE.
