Abstract: A method for use in selecting a cell or cells, from amongst a set of cells in a cellular wireless network, for coordinated use in multi-cell multiple-input/multiple-output (MIMO) transmission so as to reduce feedback overhead, each cell of the said set having at least one MIMO channel characteristic which may vary with time at a measurable rate, comprises a cell selection process comprising the steps of: identifying a cell or subset of cells of the said set for which the time variation rate/rates of the said MIMO channel characteristic is/are the slowest of those of the cells in the said set; and selecting a cell or cells for use in multi-cell MIMO transmission from only the cell or subset of cells identified in the identifying step.

Abstract: A method for cooperative data transfer includes establishing a primary wireless connection with a primary access station. The primary wireless connection uses a primary synchronization channel that is transmitted during a first frame of a super frame. The super frame comprises a plurality of frames. The method also includes detecting a secondary synchronization channel generated by an alternate access station during a subsequent frame of the super frame. The method further includes determining whether the detected secondary synchronization channel has a signal strength greater than a threshold signal strength. The method additionally includes receiving permission to begin a cooperative data transfer operation with both the primary access station and the alternate access station.
