METHOD AND SYSTEM FOR REDUCED COMPLEXITY CHANNEL ESTIMATION AND INTERFERENCE CANCELLATION FOR V-MIMO DEMODULATION
First Claim
1. A method for wireless communication in a wireless communication network, the wireless communication network having a plurality of mobile terminals arranged in virtual multiple input, multiple output (“
- V-MIMO”
) communication with a base station, the method comprising;
receiving an uplink reference signal from each of the plurality of mobile terminals;
determining a first reference signal channel estimate for each of the plurality of mobile terminals based on the corresponding received reference signal;
determining an interference cancelled estimate for each of the plurality of mobile terminals using the corresponding first reference signal channel estimate; and
determining a corresponding second reference signal channel estimate for each of the plurality of mobile terminals based on the corresponding interference cancelled estimate.

Abstract
A method and system for wireless communication in a wireless communication network. The wireless communication network has a first mobile terminal and a second mobile terminal arranged in virtual multiple input, multiple output (“V-MIMO”) communication with a base station. A first wireless communication uplink channel corresponding to the first mobile terminal is estimated. The estimate is based on a first reference symbol signal and the cancellation of interference from a second reference symbol signal received from the second mobile terminal. A second wireless communication uplink channel corresponding to the second mobile terminal is estimated. The estimate is based on the second reference symbol signal and the cancellation of interference from the first reference symbol signal received from the first mobile terminal. The estimated first wireless communication uplink channel is used to demodulate a first data signal received from the first wireless device, and the estimated second wireless communication uplink channel is used to demodulate a second data signal received from the second wireless device.
