The invention presents a method for measuring signal quality of a user equipment (UE) in wireless communication networks, comprising: communicating UE sends a cooperative measurement request to its neighboring UEs to delegate the neighboring UEs to carry out cooperative measurement; if at least one of the neighboring UEs agrees to carry out the cooperative measurement, the neighboring UE utilizes idle timeslots to perform corresponding cooperative measurements according to the received cooperative measurement request; then, the neighboring UE sends measurement result to the communicating UE or the network according to the request to finish the whole measurement process. By adopting the cooperative measurement method in the present invention, communicating UE can delegate the measurement task to its neighboring UEs, so that it can be extricated from overloaded measurement and therefore it avoid the impact of measurement operation on current communication speed and QoS.
