Patent ID: 8654705

Claim:
A method of communicating in an Evolution Data Optimized (EV-DO) network performed by an access terminal having a plurality of antennas, the method comprising: determining a number of reverse link data streams to transmit; determining a selection of antennas from the plurality of antennas for transmitting the reverse link data streams; determining beamforming parameters based at least in part on a beamforming identifier; transmitting a first data stream comprising a first medium access control (MAC) index using the selection of antennas, the first data stream being transmitted via the selection of antennas in accordance with the beam-forming parameters; and transmitting a second data stream comprising a second MAC index, the second data stream being transmitted in response to determining that the number of reverse link data streams is at least two, the second data stream being transmitted concurrently with the first data stream, and the second data stream being transmitted via the selection of antennas using a beam direction that is orthogonal to a beam direction of the first data stream.
