  • Orthogonal frequency division multiplexing (OFDM) transmit protocol selection based on a feedback loop lag condition
    Patent number: 10321460
    Abstract: An Orthogonal Frequency Division Multiplexing (OFDM) access point receives and processes beamforming feedback data from User Equipment (UE) to form a beamforming feedback loop, transmits a beamformed radio signal to the UE, and determines if the beamforming feedback loop is experiencing a beamforming lag condition, and if so, switches to a closed-loop spatial multiplexing transmit protocol. The OFDM access point receives and processes closed-loop spatial multiplexing feedback data from the UE to form a closed-loop spatial multiplexing feedback loop, transmits a closed-loop spatial multiplexed radio signal to the UE, and determines if the closed-loop spatial multiplexing feedback loop is experiencing a spatial multiplexing lag condition, and if so, switches to an open-loop spatial multiplexing transmit protocol.
