Abstract

The invention belongs to the technical field of the multimedia multicast, and discloses a video multicast method under a high load scene. The method comprises the following steps: sending video streamto multicast user equipment in a multicast group by a base station; determining a target frame needing to retransmit according to feedback information sent by the multicast user equipment, and performing the retransmission; determining ACK equipment and NACK equipment; acquiring CQI level of any ACK equipment and any NACK equipment on any channel, and selecting corresponding relay user equipmentand multiplying channel for each NACK equipment, thereby enabling the relation between multiple sets of ACK equipment selected as the relay user equipment and multiple channels selected as the multiplying channels is the one-to-one corresponding relation; sending a retransmission indication message to the relay user equipment to indicate the relay user equipment to retransmit the current target frame to the NACK equipment. Through the method disclosed by the invention, the interference between the cellular communication and the D2D communication can be reduced, the utilization rate on the wireless resource is improved, and the problem of wireless resource shortage is solved.

Description

technical field [0001] The present invention relates to the technical field of multimedia multicasting, in particular to a video multicasting method in a high-load scenario. Background technique [0002] With the rapid development of the Internet and smart terminals, multimedia services represented by video downloads and online live broadcasts have experienced explosive growth in wireless communication systems, which is critical for current 4G mobile broadband networks or future 5G networks. A big problem. Facing this problem, how to use limited spectrum resources for efficient video transmission becomes crucial. [0003] One of the important solutions is the multicast technology, which uses the characteristics of wireless transmission to simultaneously transmit video data to multiple users in the same frequency band. Due to the high spectrum utilization rate, video multicasting plays an increasingly important role in multimedia services. Especially in some practical appl...
