Abstract: A wireless communications system is presented that adapts its mode of operation between spatial and non-spatial multiplexing in response to transmission-specific variables. Mode determination logic determines, in response to a received signal, if spatial or non-spatial multiplexing should be used to transmit a subscriber datastream between the BTS and the UE. The mode determination logic receives a measure of a transmission characteristic of the signal, compares the transmission characteristic to a transmission characteristic threshold and selects either spatial or non-spatial multiplexing in response to the comparison. The transmission characteristic includes at least one of delay spread, post-processing signal-to-noise ratio, CRC failure, residual inter-symbol interference, mean square error, coherence time, and path loss.

Abstract: A method of Software-Defined Networking (SDN) switching. A packet of a flow is received onto a SDN switch via a NFX circuit. The NFX circuit determines that the packet matches a flow entry stored in any flow table in the NFX circuit, counts the number of packets of the flow received, and determines that the number of packets of the flow received is above a threshold value. The NFX circuit then forwards the packet to a NFP circuit in the SDN switch. The NFP circuit determines that the packet matches a flow entry stored in the flow table in the NFX and generates a new flow entry that applies to a relatively narrow subflow of packets that is forwarded to and stored the flow table in the NFX circuit. A subsequent packet of the flow is switched by the SDN switch without forwarding the packet to the NFP.
