In some embodiments, the invention includes a device and bus transaction control circuitry to provide bus transactions with tag space, wherein under some conditions at least part of the tag space is used to provide debug information and under some conditions at least part of the tag space is used to represent a transaction number. RFID tags containing directions to an award processing center and other unique coded information are placed at locations where customer patronage is to be encouraged. However, rather than automatically process subsequent transmissions received from the base station as if the base station properly received the antenna control bits and applied the computed antenna weights, the mobile station attempts to determine the antenna weights actually applied at the base station, and uses these determined antenna weights for processing the subsequent transmissions.
