Embodiment Construction

[0042] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0043] The MBMS transmission method disclosed by the present invention comprises the following steps:

[0044] The base station sends the MBMS service to the terminal; the base station receives the feedback information sent by the terminal.

[0045] Such as figure 1 Shown is a flow chart for implementing the MBMS transmission method of the present invention.

[0046] S101. The base station sends an MBMS service.

[0047] The main features of MBMS services are large data volume, strong real-time performance, and wide coverage. As an embodiment of the present invention, the following describes the present invention in detail by taking the MBMS service in the LTE system as an example. In the LTE system, an extended CP (Cycle Prefix, cyclic prefix) is always used for MBMS transmission, and the transmission bandwidth occupies t...

Abstract

The present invention discloses an MBMS transmission method comprising steps that upstream and downstream communication between a base station and a terminal is in a time-division duplex mode, the base station sends MBMS services to the terminal from downstream service sub-frames; the base station receives the feedback information sent by the terminal from upstream servicer sub-frames, and the ratio of the upstream servicer sub-frames and the downstream service sub-frames is smaller than 1. The present invention also discloses an MBMS transmission system and devices. By adopting the technicalsolution of the invention, downstream multimedia broadcast services of high speed can be provided for subscribers, downstream resources of the system can be fully used, and resource waste because of idle downstream sub-frames can be avoided. Otherwise, an upstream feedback mechanism is introduced, the whole performance of the system can be improved, service types can be enriched, operation management becomes more convenient and the invention is beneficial to further optimization of system performances.

Description

technical field [0001] The present invention relates to the field of mobile communication, specifically, the present invention relates to the technical field of MBMS of mobile communication. Background technique [0002] In order to effectively utilize mobile communication network resources, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) proposed MBMS (MultimediaBroadcast Multicast Service, Multimedia Broadcast Multicast Service) for mobile communication networks, thereby providing a data The point-to-multipoint service that the source sends data to multiple users realizes the sharing of network resources and improves the utilization rate of network resources, especially the sharing of air interface resources. [0003] The MBMS proposed by 3GPP can not only realize the multicast and broadcast of plain text and low-rate messages, but also realize the multicast and broadcast of high-speed multimedia services, which undoubtedly conforms to the tre...
