Abstract
Methods and apparatus for establishing multiple connections between a wireless device and multiple base stations and transferring data using these connections via different segments of an orthogonal frequency division multiple access (OFDMA) frame are provided. The multiple connections may be used for multi-way (e.g., three-way) concurrent processing, multi-way (e.g., three-way) handover, or a hybrid between concurrent processing and multi-way handover in an effort to increase data throughput for the wireless device.
