1. A method for selectively transmitting data using spatial diversity, the method comprising:

  • determining, by a controller of a portable communication device having multiple transmitters, that data is to be transmitted to a base station device using one or more of the multiple transmitters;

    identifying, based on a priority level criterium and by the controller of the portable communication device, a first portion of the data as priority data;

    identifying, based on the priority level criterium and by the controller of the portable communication device, a second portion of the data as non-priority data;

    transmitting, based on the identifying the second portion of the data as non-priority data and by the portable communication device, the second portion of data to the base station device without using spatial diversity via one of the multiple transmitters of the portable communication device; and

    transmitting, based on the identifying the first portion of the data as priority data and by the portable communication device, the first portion of the data to the base station using spatial diversity, the first portion of the data transmitted using spatial diversity by;

    creating, based on the first portion of the data, identical first and second data streams;

    designating a first transmitter of the multiple transmitters by which to transmit the first data stream over a channel;

    determining whether a second transmitter of the multiple transmitters is idle to facilitate transmission of the second data stream over the channel;

    requesting, if the second transmitter of the multiple transmitters is not idle, an uplink schedule grant effective to queue the second data stream for subsequent transmission by the second transmitter;

    activating, when the second transmitter is idle, the second transmitter to enable transmission over the channel; and

    transmitting the first and second data streams of the first portion of the data using the first transmitter and the second transmitter, respectively.
