In broadband wireless access system, base station with router and multiple user stations being connected to includes following parts: listening module in use for listening message between user station and router, or module of message proxy in use for intercepting message between user station and router; module for maintaining forwarding table of multicast address, module for executing multicast forwarding are in use for allotting an identical connection id for all user station in multicast group in order to manage adding or removed group of user station, or maintaining user data, and sending multicast data to user station. The invention also discloses relevant method. User stations in multicast group are not possible to receive multicast message by using the invention so as to reduce power consumption of user station, and raise safety. Moreover, equipment in base station does not need to carry out replication of multicast packet so as to save bandwidth resource of aerial port.

The present invention relates to a method for signaling a plurality of transmission parameters for a plurality of communications between a primary station and a plurality of respective secondary stations in a multi-user MIMO mode, comprising the steps of (a) signaling the value of at least one first transmission parameter in a multicast message to at least two secondary stations, the value of the first transmission parameter being common to the respective communications corresponding to the at least two secondary stations, and (b) signaling the value of at least one second transmission parameter in a plurality of unicast messages to each secondary stations of the plurality of secondary stations.
