Dynamic data transmission adjustment method
A dynamic data transmission adjustment method in a wireless communication system. The system includes a base station and a user equipment. The base station and the user equipment communicate amongst themselves by using a first transmission technique. The method includes transmitting a plurality of frames between the base station and the user equipment using a regular transmission scheme according to the first transmission technique, and at least one iteration of the following steps: calculating a specific error rate in at least one specific region of the transmitted frames; and adjusting the regular transmission scheme when a value representative of the specific error rate associated to the specific region exceeds a predetermined threshold.
