Abstract

Devices, systems, and methods are presented for a wireless base station to assign dynamically a plurality of radio transceiver chains among a varying number of wireless channels. In this manner, the communication system including the wireless base station may transition between a range extension mode and an enhanced capacity mode. In the range extension mode, a system is configured for maximum communication range with Subscriber Stations that are relatively distant from the radio transceiver chains, although communication is still possible with nearby Subscriber Stations. In the enhanced capacity mode, the system is configured for maximum communication throughput with Subscriber Stations that are relatively near to the radio transceiver chains, whereas communication with relatively distant Subscriber Stations will be either terminated or at least non-optimized.

Claims

1. A wireless base station allocating spectrum in a wireless network, the wireless base station comprising:

a network processor coupled to a first core network and a second core network through a network tunnel;

a baseband processor coupled to the network processor, the baseband processor executing a software instance; and

a radio transceiver chain coupled to the baseband processor, the radio transceiver chain implementing a first radio access network and a second radio access network, the first radio access network corresponding to the first core network and the second radio access network corresponding to the second core network, data transmitted between the first radio access network and the first core network forming a first network, data transmitted between the second radio access network and the second core network forming a second network;

wherein an available spectrum allocated for traffic on the first network and for traffic on the second network is dynamically allocated.

2. The wireless base station of claim 1 wherein the network processor monitors a data requirement of the first core network and the second core network and dynamically allocates the available spectrum to the first network and to the second network based on the data requirement of the first core network or the second core network.

3. The wireless base station of claim 2 further comprising a second network tunnel, the network tunnel carrying traffic for the first network and the second network tunnel carrying traffic for the second network, the network processor creating the network tunnel and the second network tunnel.

4. The wireless base station of claim 1 wherein the baseband processor monitors a data rate of the first radio access network and a data rate of the second radio access network and dynamically allocates the available spectrum to the first network and to the second network based on a data requirement of the first radio access chain or the second radio access chain.

5. The wireless base station of claim 4 further comprising a second software instance, the software instance performing tasks related to data transfer on the first network, the second software instance performing tasks related to data transfer on the second network.

6. The wireless base station of claim 1 wherein the baseband processor subdivides the radio transceiver chain into a first sub-chain and a second sub-chain, the first sub-chain implementing the first radio access network, the second sub-chain implementing the second radio access network.

7. The wireless base station of claim 1 wherein the baseband processor generates a compound signal and the radio transceiver chain implements the first radio access network and the second radio access network using the compound signal.
