Abstract: A method of operating a wireless communication system is disclosed. The method includes communicating by a first data frame having a first transmit time interval with a first wireless transceiver and communicating by a second data frame having a second transmit time interval different from the first transmit time interval with a second wireless transceiver. Data is transferred between the first data frame and the second data frame.

Abstract: Systems and methods are provided for a radar processing chain for frequency-modulated continuous wave radar systems. A transmitter transmits a plurality of chirps, each comprising an electromagnetic radiation signal, at a region of interest. A receiver front-end receives reflected electromagnetic radiation for each chirp and generates a time series of beat-signal samples for each chirp at each antenna of a plurality of antennas. A signal processor detects objects within the region of interest by providing a frequency domain representation of each time series of beat-signal samples as sample values for a set of range bins representing respective distances from the receiver, correcting the sample values for each of the set of range bins to provide a set of clutter corrected samples for each range bin, and determining an angular spectrum for each of a subset of the set of range bins from the clutter corrected samples.

Abstract: A method of operating a wireless communication system is disclosed. The method includes receiving allocation information for a plurality of second wireless transceivers from a first wireless transceiver by one of the second wireless transceivers on a physical broadcast channel (PBCH). The one of the second wireless transceivers decodes the allocation information for the plurality of second wireless transceivers. The one of the second wireless transceivers receives procedural information on a physical downlink control channel (PDCCH) in response to the decoded allocation information

Abstract: A method of operating a wireless communication system is disclosed. The method includes receiving first and second parallel data streams. The first data stream is converted to a first frequency-domain data stream by a discrete Fourier transform (DFT) having NDFT0 size, where NDFT0 is a positive integer. The second data stream is converted to a second frequency-domain data stream by a DFT having NDFT1 size, where NDFT1 is a positive integer. The first and second frequency-domain data streams are mapped to respective subcarriers.
