Abstract:
1. A method comprising: receiving an input data stream and generating one or more orthogonal frequency division multiple access (OFDMA) symbols, the one or more OFDMA symbols distributed across a plurality of physical resource units of a frequency band; mapping a first set of the plurality of physical resource units to a first transmit chain of a wireless communication device, the first set defined by a first frequency partition, having a first range of contiguous frequencies, uniquely assigned to the first transmit chain; mapping a second set of the plurality of physical resource units to a second transmit chain of the wireless communication device, the second set defined by a second frequency partition, having a second range of contiguous frequencies, uniquely assigned to the second transmit chain; and transmitting the first and second sets by the first and second transmit chains, respectively, to a receiving device, wherein each of the first and second transmit chains includes a transmitter and an antenna.
