Embodiment Construction
[0035] The present invention provides a method for implementing broadcast and multicast in a wireless communication system, so that during the process of sending broadcast and multicast data, the interference between wireless service terminals of the local cell and adjacent cells of the same frequency in the network can be effectively reduced.
[0036] To achieve this goal, the idea of the present invention is:
[0037] The network side sends the sending scheduling information of the shaped feature code to the cell terminal and the correspondence between the shaped feature code and the broadcast and multicast data sent by the network side. Among them, the sending scheduling information of the shaped feature code contains the time interval for sending the shaped feature code.
[0038] The terminal sends a signal carrying a shaped feature code to the network side according to the sending scheduling information, where the shaped feature code corresponds to broadcast multicast data req...

The invention discloses a method to realize the group broadcast in the wireless communication system, the method includes: the sending dispatching information of shaped characteristic code sent by the terminal of web lateral section and the relationship between the shaped characteristic code and the data of group broadcast. Thereinto, the sending dispatching information of shaped characteristic code contains the time interval of shaped characteristic code. The terminal which needs to receive the data of group broadcast sends the signal which takes the shaped characteristic code according to the said relationship. The web side detects the information of direction angle of shaped characteristic code, and controls the wave-packet shape of descending signal of intelligent antenna using the said information of direction angle, and sends the relative data which relative to the shaped characteristic code at the direction angle.
Description
Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method for realizing broadcast and multicast in a wireless communication system. Background technique [0002] The 3G (The 3rd Generation) mobile communication system can not only transmit high-quality point-to-point multimedia voice and data services, but also transmit point-to-multipoint broadcast and multicast services that have higher requirements than existing data services. , Such as online movie and video on demand, TV broadcasting, multimedia broadcast / multicast service (MBMS, Multimedia Broadcast / Multicast Service), etc. According to the current 3rd Generation Mobile Communication System Partnership Project (3GPP, 3rd Generation Partnership Project) specifications, MBMS service transmission mainly uses point-to-multipoint radio bearers (PTM RB, Point-To-Multipoint Radio Bear) or point-to-multipoint radio bearers. Point-To-Point Radio Bear (PTP RB) t...
