Problems solved by technology

In the prior art, a similar way of obtaining resource configuration across cells has been used in the Device to Device (D2D) technology, but the defect of the prior art is that each user needs to apply to the cell to obtain other cell resource configuration, and this cell uses unicast configuration for each user who needs to read the multicast services of other cells to configure the resource location for sending / reading multicast services transmitted by other cells, resulting in a large amount of signaling overhead

Abstract

A multicast transmission method, a base station of a first cell acquires first multicast resource information of at least one second cell, the base station of the first cell and the base stations of each of the second cells are different base stations; the first cell The base station sends second multicast resource information to the user equipment, where the second multicast resource information is used to indicate resource configuration for transmitting multicast service data to each of the second cells. The base station of the first cell actively broadcasts the acquired multicast resource information to the user equipment, so that the base station of the first cell does not need to configure sending / reading of each second cell in unicast mode for each user equipment The resource location of the multicast service data reduces the signaling overhead.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a multicast transmission method, base station and user equipment. Background technique [0002] With the rapid development of the Internet and the popularity of large-screen multifunctional user equipment (UE), a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, television broadcasting, video on demand, advertising, online Education, interactive games, and Internet of Vehicles, etc. These services not only meet the multi-service needs of mobile users, but also bring new business growth points for operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume and long duration. [0003] In order to effectively utilize mobile network resources,...
