Abstract: This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitting device may transmit a sounding dataset, over a wireless channel, to a receiving device. The sounding dataset may include information carried in one or more training fields configured for channel estimation and sounding control information based, at least in part, on a configuration of the transmitting device.

Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.

Abstract: Radio equipment (10) is configured for tap separated channel estimation in a wireless communication system. The radio equipment (10) obtains a channel estimate (16) of a radio channel over which a reference signal (12) is received, and separates the channel estimate (16) into channel estimate components (20) that correspond to respective channel taps (22). The radio equipment (10) then compensates the channel estimate components (20) for Doppler shifts respectively associated with the channel taps (22) to which the channel estimate components (20) correspond. The radio equipment (10) processes the compensated channel estimate components (32) separately. Such processing comprises filtering, interpolating, and/or extrapolating. The radio equipment (10) then de-compensates the processed channel estimate components (34) for the respective Doppler shifts, and forms a combined channel estimate (42) of the radio channel by combining the de-compensated channel estimate components (38).

Abstract: Methods, systems, and devices are described for fountain hybrid automatic repeat request (HARD) for reliable low latency communication. A wireless device may transmit a data block based on a low latency operational mode. The device may then transmit a number of redundancy versions of the data block prior to determining whether an acknowledgement (ACK) has been received. In some examples the ACK may be an augmented ACK, which may be based on the number of redundancy versions received prior to successfully decoding the data block, and which may include an additional resource request. In some examples, the device may select an updated modulation and coding scheme (MCS) based on the augmented ACK. In some examples, the device may increase a number of frequency resources (e.g., component carriers) used for transmission based on the augmented ACK.
