1. A computer-implemented method for operating an access node, comprising:
receiving, by the access node from a user equipment (UE), information on a maximum number of multiple input multiple output (MIMO) layers supported by the UE for an operation bandwidth within a system bandwidth operated by the access node, the operation bandwidth being less than the system bandwidth;
scheduling, by the access node for the UE, a bandwidth for data communications in accordance with the maximum number of MIMO layers supported by the UE;
sending, by the access node to the UE, allocation information related to the bandwidth; and
communicating, by the access node with the UE, a data frame on the bandwidth.
