Orthogonal frequency division multiplexing (OFDM) transmit protocol selection based on a feedback loop lag condition

An Orthogonal Frequency Division Multiplexing (OFDM) access point comprising:

• a data processing system configured to process beamforming feedback data received by a wireless communication transceiver from User Equipment (UE) to form a beamforming feedback loop, and the wireless communication transceiver configured to responsively transmit a beamformed radio signal to the UE;
• the data processing system configured to determine that the beamforming feedback data is randomly changing in response to adjustments, and responsively switch to a closed-loop spatial multiplexing transmit protocol;
• the data processing system configured to process closed-loop spatial multiplexing feedback data received by the wireless communication transceiver from the UE to form a closed-loop spatial multiplexing feedback loop, and the wireless communication transceiver configured to responsively transmit a closed-loop spatial multiplexed radio signal to the UE;
• the data processing system configured to determine that the closed-loop spatial multiplexing feedback data is randomly changing in response to adjustments, and responsively switch to an open-loop spatial multiplexing transmit protocol;
• and
• the data processing system configured to process open-loop spatial multiplexing feedback data received by the wireless communication transceiver from the UE to form an open-loop spatial multiplexing feedback loop, and the wireless communication transceiver configured to responsively transmit an open-loop spatial multiplexed radio signal to the UE.
