Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0014] EOC (Ethernet Over Cable, collectively referred to as the technology for transmitting Ethernet data over coaxial cables) is a typical point-to-multipoint system using OFDM (Orthogonal Frequency Division Multiple) technology. In addition, the point-to-multipoint system using OFDM technology also includes WIMAX (Worldwide Interoperability for Microwave Access) system, LTE (Long Term Evolution) system, etc. in the wireless communication system.

Abstract

The embodiment of the invention provides a method for improving a multicast reception gain, comprising the steps of using a receiving end to receive indication information come from a sending end; using the receiving end to obtain same source multicast group information according to the indication information; using the receiving end to receive a first physical resource block and a second physical resource block come from a same multicast source and loading same data; using the receiving end to merge and process the data loaded by the first physical resource block and the second physical resource block to improve the multicast reception gain.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for improving multicast receiving gain. Background technique [0002] There are two traditional IP communication methods: one is point-to-point communication between the source host and the destination host, that is, unicast; the other is point-to-multipoint communication between the source host and all other hosts in the same network segment Communication, that is, broadcasting. If you want to send information to multiple hosts instead of all hosts, if you use the broadcast method, you will not only waste bandwidth by sending the information to unnecessary hosts, but you will not be able to send information across network segments; if you use the unicast method, repeat The IP packets not only occupy a lot of bandwidth, but also increase the load of the source host. Therefore, the traditional unicast and broadcast communication methods cannot ...
