A process for the adaptation of a radio link in a network having to based medium access area contention

摘要

The invention concerns a method for radio link adaptation suitable for use in a communication network with a contention-based medium access mechanism such as CSMA/CA, said network comprising at least a first terminal and a second terminal, characterized by the steps, for testing the reception by the first terminal (MT1) of data sent by the second terminal (MT2) of:setting of a parameter value having an influence on the transmission from the second terminal to the first terminal (e.g. to influence the data rate or the antenna characteristics),generation by the first terminal (MT1) of a message to the second terminal (MT2) for triggering a predetermined response from the second terminal to the first terminal, wherein the predetermined response has a content known in advance to the first terminal and is received at a time known in advance by the first terminal and wherein the predetermined response is received according to conditions defined by the previously set parameter value;evaluation by the first terminal of a quality criterion of the predetermined response.
