Abstract:
The base stations in a coordinating set, i.e., CoMP set, implement distributed V-MIMO processing to decode uplink signals transmitted from multiple user terminals over the same time and frequency resources. Each base station uses the extrinsic information received from its coordinating base stations to facilitate demodulation and decoding. In the event that one of the base stations successfully decodes an uplink signal, it may provide the decoded data to the other coordinating base stations in the coordinating set. In this case, the coordinating base stations do not need to decode the uplink signal. Even if the uplink signal is not successfully decoded, the demodulated data received from the coordinating base station increases the likelihood of successfully decoding uplink signal in the next iteration of a HARQ process.
