Patent ID: 8295237

Claim:
A scheduling method for a base station which transmits an identical packet or data to mobile stations via a plurality of transmission antennas based on a transmission diversity system, the method comprising: monitoring a transmission phase (first transmission phase) for each mobile station, when a packet is diversity-transmitted to mobile stations using a shared channel, and monitoring a transmission phase (second transmission phase) for each mobile station, when data is diversity-transmitted to other mobile stations using a dedicated channel; calculating, by making use of the first and second transmission phases for each shared channel mobile station to which pilot is diversity-transmitted using the shared channel, a degree of interference in all the dedicated channel mobile stations to which data is diversity-transmitted using the dedicated channel, the interference being generated when a packet is diversity-transmitted to the shared channel mobile station; and transmitting a packet to a predetermined shared channel mobile station preferentially, according to the degree of interference.
