Abstract
Methods and systems are provided for restricting an uplink Multiple Input Multiple Output (MIMO) assignment based on fading in an mmWave system. The methods and systems receive fading data from one or more user devices. Based on the received fading data, the methods and systems determine that a threshold number of the one or more user devices satisfies a threshold level of fading. In response to the threshold number satisfying the threshold level of fading, the methods and systems dynamically restrict the uplink MIMO assignment for at least one user device satisfying the threshold level of fading. In response to dynamically restricting the uplink MIMO assignment, the methods and systems assign the at least one user device to a lower MIMO layer of available MIMO layers.
