摘要
A wireless communication system and an apparatus and method for determining a network transmission mechanism are provided. The apparatus stores several transmission policies. Each transmission policy corresponds to a predetermined strength distribution and includes a first predetermined transmission mechanism and a second predetermined transmission mechanism. The apparatus determines a real strength distribution among several terminal apparatuses according to their signal strength, determines a selected policy based on the real strength distribution and the predetermined strength distributions, and determines a user transmission mechanism for each terminal apparatus. Each user transmission mechanism includes the first predetermined transmission mechanism and/or the second predetermined transmission mechanism of the selected policy. The network transmission mechanism includes the user transmission mechanisms. The apparatus transmits an indication signal to each terminal apparatus to inform of the corresponding user transmission mechanism. Each terminal apparatus transmits data according to the corresponding user transmission mechanism.
