ABSTRACT:
Methods and apparatus for supporting the communication of an information stream using an individual polarization type are described. For example, a first data stream is communicated from a base station sector transmitter using horizontal polarization signals and a second data stream is communicated using vertical polarization signals. A mobile wireless communications device, employing a plurality of dipole antennas associated with different direction polarizations, e.g., a first direction horizontal polarization dipole antenna, a second direction horizontal polarization dipole antenna and a vertical polarization dipole antenna, multiple receiver modules, and a combiner module, facilitates the recovery of horizontal polarization signals without the need for azimuth antenna orienting or repositioning, and also facilitates the recovery of vertical polarization signals. The first data stream associated with horizontal polarization may be, and sometimes is, transmitted concurrently with the second data stream associated with vertical polarization using the same time/frequency air link resources, e.g., segment.
