Abstract: In some aspects, a radar device may receive a received signal comprising a reflected frequency modulated continuous wave (FMCW) radar signal and interference. The radar device may identify the reflected FMCW radar signal based at least in part on performing a phase based search procedure to facilitate removing the interference from the received signal. The radar device may perform an action based at least in part on a characteristic of the identified reflected FMCW radar signal. Numerous other aspects are described.

Abstract: The present disclosure provides methods and apparatus for configuring an image data transfer time for sending image data from a processor to a display panel along a display path. One method includes receiving, by the processor from the display panel, a display panel refresh interval indication indicating a display panel refresh interval of the display panel. The display panel refresh interval of the display panel corresponds to a time duration of a display period of the display panel. The display panel is configured to refresh each display period. The image data transfer time is computed based on the display panel refresh interval. One or more components of the display path are configured to support the computed image data transfer time.

Abstract: In general, aspects disclosed herein provide techniques for processing video data. Certain aspects provide a method for processing video data comprising a plurality of frames for display on a display as discussed herein. The method includes determining a sampling rate (N) based on a frame rate used for displaying the video data on the display. The sampling rate N is greater than 1. The method further includes, for every N frames of the plurality of frames, processing one or more statistics associated with a frame determine one or more display settings. The method further includes outputting to the display the corresponding N frames of the plurality of frames using the one or more display settings.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: An apparatus is disclosed for radar interference mitigation using a pseudorandom offset. The apparatus includes an antenna array and a wireless transceiver. The wireless transceiver is coupled to the antenna array and is configured to transmit, via the antenna array, a radar transmit signal based on at least one pseudorandom offset. The wireless transceiver is also configured to receive, via the antenna array, at least a portion of another radar transmit signal from another apparatus. The wireless transceiver is additionally configured to receive, via the antenna array, a radar receive signal that includes a portion of the radar transmit signal that is reflected by an object. At a given time, a frequency of the radar receive signal is different than a frequency of the radar transmit signal based on the at least one pseudorandom offset.

Abstract: Apparatus and methods are disclosed for determining, on a small form factor 5G communication device, the range of a target object include receiving, at a receiving antenna of the small form factor communication device, a composite signal where the composite signal includes a target reflection signal and a mutual coupling (MC) leakage signal, generating a composite beat waveform by mixing the composite signal with an original signal, where the composite beat includes target beat and MC leakage beat waveform components, isolating the target beat waveform by subtracting from the composite beat waveform a weighted, k-delayed composite beat waveform, where for a configured k the target beat waveforms are uncorrelated and the MC leakage beat waveforms are correlated, and determining, using the target beat waveform, a range of the target object from the small form factor device.

Abstract: Devices and methods for reducing a DPU transfer time to compensate for a delayed GPU render time. After completion of rendering a second frame that follows a first frame, a frame processor determines whether the first frame is currently transferring to a display panel or has already been transferred to the display panel. At least one clock is used with a first set of clock speeds when the first frame is determined to be currently transferring and used with a second set of clock speeds when the first frame is determined to have already been transferred, the second set of clock speeds being faster than the first set of clock speeds. After completion of the transfer of the first frame, the second frame is transferred based on the set of clock speeds.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating, in a display panel, a virtual mask layer around a cutout region for a front camera. The front camera may be positioned under the display panel and receive light through the cutout region. The mask layer may hide defects of the cutout region that does not have functional pixels. The disclosed techniques may improve aesthetic appearance of displays having punch-hole cameras with reduced hole sizes and increased production quality conformance rate.
