Method for obtaining MBMS (Multimedia Broadcast Multicast Service) dynamic scheduling information and user equipment

Abstract

A method and a user equipment for acquiring dynamic scheduling information of Multimedia Broadcast Multicast Service (MBMS) are provided. The user equipment continues to parse MBMS scheduling blocks to acquire the dynamic scheduling information of MBMS, while during the parsing, if a next multicast sub-frame arrives, the multicast sub-frame is received simultaneously. After completing the parsing, if a multicast sub-frame has been received during the parsing, the user equipment reserves or discards the multicast sub-frame received during the parsing according to the indication of the dynamic scheduling information of MBMS, and receives the subsequent corresponding MBMS according to the indication of the dynamic scheduling information of MBMS. Through the method, the user equipment parses the dynamic scheduling information of MBMS while receiving the multicast sub-frames, therefore transitory information absence of UE dynamic scheduling is eliminated and the problem of missing data to be received is avoided, thus the accuracy of receiving MBMS by the UE is improved.

Description

technical field [0001] The invention relates to a multimedia broadcast and multicast service (MBMS, Multimedia Broadcast Multicast Service), especially a method for acquiring MBMS dynamic scheduling information and user equipment. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertisements, online education, interactive games, etc. On the one hand, it meets the ever-increasing business demands of mobile users, and at the same time brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, mobile data multimedia services have the characteristics of large data volume, long du...

AI Technical Summary

Problems solved by technology

For the UE, there is no indication of the dynamic scheduling time for a period of time such as 2-3ms, resulting in the lack of short-term dynamic scheduling information of the UE, and the problem of missing data to be received is likely to occur, thereby reducing the UE's ability to receive MBMS services. accuracy
