A METHOD AND A DEVICE FOR ADAPTIVE CONTROL SIGNALLING

摘要

The invention discloses a method for use in a wireless access system, in which system at least a first user terminal can be assigned a first contiguous frequency spectrum for the exchange of data and control signals with the base station, and in which system the exchange of control signals between the second user terminal and the base station can be placed in connection to said first spectrum for the first user terminal. According to the method, measurements of the level of interfering signals in said first spectrum are made, and in the exchange of control signals between the second user terminal and the base station is placed in or adjacent to the first spectrum, depending on the measured interference level.
