Abstract:
1. A method for performing, by a base station, an uplink scheduling in a spatial multiplexing system, the method comprising: determining one of a single-input multiple-output (SIMO) mode and a collaborative spatial multiplexing (C-SM) mode as an uplink transmission mode to be used by a mobile station, based on at least one of channel status information and an uplink transmission power of the mobile station; determining a transmission format of the base station, the transmission format corresponding to the determined uplink transmission mode from the SIMO mode and the C-SM mode; adjusting a disposition of previously allocated uplink bursts of the SIMO mode and the C-SM mode within a frame, for allocation of an uplink burst according to the determined uplink transmission mode; generating resource allocating information including mode information regarding the determined uplink transmission mode, format information regarding the determined transmission format, and position information regarding allocation of the uplink bursts according to the adjusted disposition; and transmitting the resource allocating information to the mobile station.
