Abstract
Systems and methods are provided for adaptively transmitting information to a plurality of nodes in a local area of a base station. The base station receives channel quality information from one or more of the nodes within the local area, selects a transmission rate for a downlink transmission corresponding to the lowest channel qualities, and simultaneously transmits a message to the nodes at the selected transmission rate.

A method for adaptively transmitting information to a plurality of nodes in a local area of a base station, the method comprising:
- receiving channel quality information from one or more of the plurality of nodes within the local area of the base station;
- selecting a transmission rate for a downlink transmission based on the received channel quality information, the selected transmission rate corresponding to one of the lowest channel qualities;
- and
- simultaneously transmitting a message to the nodes at the selected transmission rate.
A base station that adaptively transmits information to a plurality of nodes in a local area of the base station, the base station comprising at least one processor and a memory device coupled to the at least one processor, the at least one processor being configured to:
- receive channel quality information from one or more of a plurality of nodes within the local area;
- select a transmission rate for a downlink transmission based on the received channel quality information, the selected transmission rate corresponding to one of the lowest channel qualities;
- and
- simultaneously transmit a message to the nodes at the selected transmission rate.
A computer program product comprising a non-transitory computer-readable medium having program instructions stored thereon, further comprising code for causing at least one computer to:
- receive channel quality information from one or more of a plurality of nodes within a local area of the base station;
- select a transmission rate for a downlink transmission based on the received channel quality information, the selected transmission rate corresponding to one of the lowest channel qualities;
- and
- simultaneously transmit a message to the nodes at the selected transmission rate.
A base station that adaptively transmits information to a plurality of nodes in a local area of the base station, the base station comprising:
- means for receiving over the network channel quality information from one or more of the plurality of nodes within the local area;
- means for selecting a transmission rate for a downlink transmission based on the received channel quality information, the selected transmission rate corresponding to one of the lowest channel qualities;
- and
- means for simultaneously transmitting a message to the nodes at the selected transmission rate.
