Systems and methods for cell-level beamforming mode adaptation

A system for adapting a beamforming mode, the system comprising:

• an antenna array comprising one or more antenna elements;
• and
• one or more processors configured to execute operations comprising:
• receiving, at a base station associated with the antenna array, channel state information from one or more devices;
• based on the channel state information, determining whether an uplink signal measurement is above a first threshold and whether a downlink signal measurement is above a second threshold;
• based on determining that the uplink signal measurement is above the first threshold and whether the downlink signal measurement is above the second threshold, instructing the one or more antenna elements to schedule wireless transmissions utilizing open-loop beamforming;
• and
• after instructing the one or more antenna elements to schedule wireless transmissions utilizing open-loop beamforming:
• 1) Determining, using additional channel state information, that an additional uplink signal measurement is not above the first threshold and that an additional downlink signal measurement is not above the second threshold;
• and
• instructing the one or more antenna elements to schedule the wireless transmissions utilizing closed-loop beamforming based on the additional uplink signal measurement not being above the first threshold and based on the additional downlink signal measurement not being above the second threshold;
• or
• 2) Determining that an additional uplink signal measurement is not above the first threshold and that an additional downlink signal measurement is above the second threshold;
• and
• instructing the one or more antenna elements to schedule the wireless transmissions utilizing closed-loop beamforming based on the additional uplink signal measurement not being above the first threshold and based on the additional downlink signal measurement being above the second threshold.
