Abstract
Among the various methods proposed to address interference problems in wireless networks, two promising ones are: Network Multi-Input-Multi-Output (often referred to as Network MIMO) decoding (which employs joint MIMO receiver processing of signals received at multiple antennas); and Multi-Cell Successive Interference Cancellation (MC-SIC). These methods have complementary strengths and limitations when implemented in a practical setting. The approach described herein attempts to combine the strengths of these two methods while working within the constraints imposed by practical implementations to provide a viable hybrid solution.
Claims15
A method comprising:
- performing, by a first cluster processor of a first cluster, joint processing of received signal vectors, each corresponding to a receive antenna associated with the first cluster;
- sending, by the first cluster processor, messaging requesting information from a second cluster processor to aid the first cluster processor in decoding signals from a transmitting device.
A cluster processor of a first cluster in a communication system, the cluster processor being configured to communicate with other devices in the system, wherein the cluster processor is operative
- to perform joint processing of received signal vectors, each corresponding to a receive antenna associated with the first cluster, and
- to send messaging requesting information from a second cluster processor to aid the present cluster processor in decoding signals from a transmitting device.
