METHOD AND SYSTEM FOR COLLISION AVOIDANCE IN WIRELESS COMMUNICATIONS

摘要

The invention concerns a method (300) and mobile unit (110) for reducing transmission collisions. The method can include - in a systemless call environment - receiving (314) at a plurality of receiving mobile units (110B, 110C) a call from an original transmitting mobile unit (110A) and in the plurality of receiving mobile units, selectively randomly delaying (316) transmissions from the receiving units to reduce the probability that such transmissions will collide with one another. The selectively randomly delaying a transmission at the receiving units step can include performing (318) a pre-transmission scan when a transmission element (112) of one of the receiving mobile units is activated or by assigning (330) a random delay to an idle mode (400) following a receive session in the receiving mobile units.
