| 20110063989 | METHOD AND DEVICE FOR CANCELING THE INTERFERENCE AMONG SIGNALS RECEIVED BY MULTIPLE MOBILE STATIONS - A Macro-Diversity HandOver (MDHO) solution based on multi-User MIMO is provided. Multiple base stations (BSs) serve the MDHO zone. By jointly precoding the modulated signals to be sent, the multiple BSs send the precoded signals to the multiple mobile stations (MSs) over the same time-frequency resources. The signal to be sent is transmitted to the multiple MSs in the MDHO zone. Due to the adoption of the precoding technique, each MS makes no or small interference to other MSs. Since the multiple BSs that serve one MDHO zone serve multiple MSs over the same time-frequency resources, the system capacity in the MDHO zone is greatly improved. | 03-17-2011 |
