Abstract
The invention is a system and method of transmitting control information and user data, relating to multicast or broadcast services, between a first information entity (110) within at least one mobile station (104) and a second information entity (114) within a controller (106) of a wireless network (102) in which the at least one mobile station is located. The process of the invention includes originating control information from at least one first information entity; encoding the control information at the at least one mobile station on a logical channel; transmitting the logical channel on a physical channel from the at least one mobile station to the controller; decoding the physical and the logical channels at the controller and providing the control information to the second information entity; providing user data at the second information entity; encoding the user data at the controller on a logical channel; encoding the logical channel, on which the user data is encoded, on a physical channel and wirelessly transmitting the physical channel on which the logical channel is encoded from the controller to the at least one mobile station; and decoding the physical channel and t…
