Title:
METHOD FOR COMMUNICATION IN CELLULAR NETWORK
Document Type and Number:
Japanese Patent JP2008172753
Kind Code:
A
Abstract:
To provide cooperative communication and shared handoff for an OFDMA cellular network.
In a cellular network, symbols are encoded and modulated to generate a modulated signal. The modulated signal is mapped to a subcarrier using a spatial mapping matrix. An inverse fast Fourier transform is applied to the mapped signal to generate groups of tones. The groups of tones are transmitted concurrently to multiple receivers using the same channel as orthogonal frequency-division multiplexing access (OFDMA) signals. There is one group of tones for each receiver.
