Abstract: Disclosed is C-SDMA and C-BF technology for effectively suppressing inter-cell interference from neighboring BTSs only by using partial channel information delivered from an AT over a limited uplink feedback channel in a collaborative wireless communication system employing an FDD scheme and including neighboring BTSs connected to each other through a high-speed wireline communication network. C-SDMA technology makes it possible to select the optimal feedback scheme by considering uplink feedback channel capacity allowed in the system. C-BF technology uses information on beamforming signal weight and main beamforming interference weight vectors to suppress collision between formed by weights that each BTS uses, thereby improving system transmission capacity. Technology providing higher system capacity is adaptively selected from among C-SDMA and C-BF by using limited feedback information, so that high system capacity is provided in various environmental conditions.
