    Abstract: PROBLEM TO BE SOLVED: To provide transceivers, including receivers, and methods of communicating OFDM signals that provide flexibility between throughput and range in wireless local area networks (WLANs).
    SOLUTION: Modern digital communication system, including WLANs, uses symbol-modulated orthogonal subcarriers as a modulation system to help signals survive in environments having multi-path reflections and/or strong interference. A reconfigurable multichannel receiver can selectively operate in increased throughput modes and/or increased range modes. The receiver can select two or more antennas to receive more than one subchannel of a wideband orthogonal frequency division multiplexed (OFDM) channel. Maximum-ratio combining can be performed on corresponding symbol-modulated subcarriers from the two or more antennas, and a single OFDM symbol can be generated from the subchannels received by the two or more antennas. In other embodiments, more than one subchannel of a wideband OFDM channel can be received through a single antenna selected from a plurality of spatially diverse antennas.

    Abstract: A quasi-parallel receiver may simultaneously receive signals within several subchannels that comprise a wideband channel. The receiver includes a subchannel filter selection switch that provides a baseband signal to a selected one of a plurality of subchannel low-pass filters. A heterodyne frequency generator provides one of a plurality of heterodyne frequencies to convert an RF signal received within a selected subchannel to the baseband signal. The subchannel low-pass filters accumulate signal information from an associated one of a plurality of subchannels during a filter-input sampling interval. In some embodiments, individual analog-to-digital converters receive the accumulated signal outputs from an associated subchannel filter and generate digital signals for a subsequent Fourier transformation. In some embodiments, a normalized signal output may be provided to the analog-to-digital converters, allowing the use of lower resolution analog-to-digital converters. The analog-to-digital converters may have sampling rates based on the subchannel bandwidth.

    Abstract: Embodiments of the present disclosure describe devices, methods, computer-readable media, and systems configurations for configuration of downlink coordinated multipoint (CoMP) communications in a wireless communication network. A user equipment (UE) may receive, from an evolved Node B (eNB), a radio resource control (RRC) transmission including channel state information (CSI) reference signal (RS) parameters for a plurality of transmission points. The UE may subsequently receive a medium access control (MAC) control element (CE) including a plurality of index bits corresponding to one or more activated transmission points of the plurality of transmission points for which the feedback module is to generate CSI-RS feedback. The eNB may dynamically update the transmission points that are activated for CSI-RS feedback. The UE may receive another MAC CE from the eNB to notify the UE of the updated set of activated transmission points.
