Abstract: The present invention provides a method of receiving a multimedia broadcast/multicast service in a user equipment of a wireless communication system based on MBSFN transmission and a method of assisting the user equipment to receive the service in the corresponding base station; wherein the user equipment receives a transport block from the base station in a predefined period; and then judges whether a notification indicator in the transport block is activated, if so, then judges whether a service identification of a multimedia broadcast/multicast service subscribed to by the user equipment is included in a transport block including a control signaling in the transport block, if so, then receives the multimedia broadcast/multicast service. By implementing the present invention, a user terminal in IDLE mode only needs a predefined period such as a DRX period to wake up to receive the notification indicator to judge whether a new service will start without waking up at extra time.

Abstract: The invention provides a method of pattern-based message transmission. The method can predetermine a transmission pattern for the message transmission between a base station and a user equipment according to a service type, an equipment identifier, and etc., of the equipment and can hereby determine a transmission process of signaling and data and thus can handle the remaining transmission of either signaling or data to be performed in the predetermined pattern, which means that scheduling resources can be greatly saved and thus signaling overheads and the resource consumption can be greatly reduced. With an optimized design of a pattern, an acknowledgement message and subsequent signalings and/or data could be encapsulated in a same data packet for transmission and reception, thereby resources are further saved. This improves the efficiency of utilizing signaling greatly in general, reduces signaling overheads, and also facilitates various communication between other users in the cell, improves the efficiency of economy and saves cost.
