Abstract: 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.

Abstract: A multimedia broadcast/multicast service (MBMS) coordination entity commands a first base station and a second base station to establish an MBMS control plane such that the second base station receives MBMS control signals from a core network on the MBMS control plane. The MBMS coordination entity also commands the first base station and the second base station to establish an MBMS user plane or commands the second base station to establish an MBMS user plane with the core network, such that the second station receives MBMS data from the core network on the MBMS user plane.
