    Abstract: A method and electronic device for motion assisted leakage removal. The electronic device includes a radar transceiver, a sensor, and a processor. The processor is configured to determine that the electronic device is in a first motion state, During the first motion state, the processor is configured to transmit a first set of signals. The processor is also configured to generate a first channel impulse response (CIR) based on the received first set of signals. The processor is further configured to apply a filter that estimates a leakage depicted by the first CIR. During a second motion state, the processor is configured to transmit a second set of signals. Additionally, the processor is configured to generate a second CIR based on the received second set of signals, and apply the estimated leakage from the first CIR to the second CIR to remove leakage from the second CIR.

    Abstract: A method of a user equipment (UE) in a wireless communication system is provided. The method comprises identifying E-field data of each antenna of the UE to be used for transmitting and receiving data, generating, based on the E-field data, a set of codewords including a first and second upper bounds, the set of codewords corresponding to candidate beams of each antenna, selecting at least one codeword from the set of codewords based on a performance criteria, configuring a codebook to be used for each antenna by adding the at least one codeword into the codebook, determining whether the codebook including the at least one codeword satisfies a condition to stop adding another codeword to the codebook, and applying the configured codebook for use in transmitting or receiving the data at each antenna based on whether the condition is satisfied.

    Abstract: Methods and apparatus for relay aided beam management in a vehicle communication system are provided. The relay comprises an antenna system including an internal antenna located inside a vehicle and an external antenna located outside the vehicle. The relay further comprises a transceiver operably connected to the antenna system, the transceiver configured to receive, from a base station (BS), a first signal via the external antenna of the antenna system, and receive, from the vehicle, configuration information including at least one of a vehicle speed, or a position of a window of the vehicle or windshield wiper. The relay further comprises a processor operably connected to the antenna system and the transceiver, the processor configured to generate a second signal based on (i) the configuration information and (ii) the first signal, wherein the transceiver is further configured to transmit, to a user equipment (UE), the second signal via the internal antenna.

    Abstract: A method and electronic device for determining relevant signals in radar signal processing. The electronic device includes a radar transceiver, a memory, and a processor. The processor is configured to cause the electronic device to obtain, via the radar transceiver of the electronic device, radar measurements for one or more modes in a set of modes; process the radar measurements to obtain a set of radar images; identify relevant signals in the set of radar images based on signal determination criteria for an application; and perform the application using only the relevant signals.

    Abstract: A method and electronic device for object detection. The electronic device includes at least a first antenna pair comprising a first transmitter antenna configured to transmit signals and a first receiver antenna configured to receive signals, a memory, and a processor. The processor is configured to control the first transmitter antenna to transmit a first signal, generate a channel impulse response (CIR) based on receiving, by the first receiver antenna, a reflection of the first signal, determine a location of at least one leakage peak in the CIR, compare a first segment of taps in the CIR prior to the at least one leakage peak with a second segment of taps in the CIR after the leakage peak, and determine an object is present based on symmetry between the first and second segments of taps.
