摘要： The present invention relates to a beamforming method for smart antenna arrays, and in particular relates to a beamforming method for smart two-dimensional antennas. Smart antennas employ arrays of low gain antennas connected to a combining/beamforming network. Smart antennas can provide enhanced coverage through range extension, hole filling and improved building penetration. By improving transmission and reception at the base station, the tolerable path losses can be increased whereby the range of the base station can be improved. A first aspect of the invention thus provides a method of generating low sidelobe beampatterns for 2-dimensional arrays. A further aspect addresses the feedback signalling techniques which are presently being considered by standard bodies for four antennas in large arrays. The invention is suitable for CDMA wireless cellular systems, as presently determined for third generation cellular wireless networks, and other wireless systems such as TDMA systems and wireless LANs.

摘要： The present invention relates to third generation cellular networks and, in particular, to the backbone ATM switching network between a base station and other base stations or other networks. The present invention seeks to provide a 3G cellular communications system with a reduced likelihood of failure. In accordance with a first aspect of the invention there is provided a third generation wireless communications network including a plurality of base station radio interfaces which provide cellular wireless coverage; at least one Node B and a radio network controller. The system is configured such that there are at least two signal paths between the said at least one node and the radio network controller whereby to provide an IMA protection mode or an IMA aggregation mode.
