Embodiment Construction

[0052] The technical solution of the present invention is mainly aimed at the network characteristics that different UEs can perform data interaction based on different transmission bandwidths and systems in a multi-frequency wireless communication system (such as an OFDM wireless communication system), and proposes to realize the system downlink based on this network characteristic. The processing method of sending broadcast and multicast service data to each UE is to solve the above-mentioned prior art that can only be implemented in a single-frequency wireless communication system (such as a WCDMA wireless communication system) to deliver broadcast and multicast service data to each UE, but cannot The problem of delivering broadcast and multicast service data to each UE in a multi-frequency wireless communication system.

[0053] The main implementation principle, specific implementation process and corresponding beneficial effects of the present invention will be described ...

Abstract

This invention discloses a send-down method for broadcast and multicast service data including: the system can select at least two different transmission bandwidths in the sphere supported by a managed user terminal and sends same broadcast and multicast service data based on the selected transmission bandwidth, besides, this invention also discloses a send-down device of broadcast and multicast service data.

Description

technical field [0001] The present invention relates to the technical field of wireless communication in which user terminals perform data interaction based on different transmission bandwidths and systems, in particular to a method and device for delivering broadcast and multicast service data. Background technique [0002] The next-generation mobile communication technology needs to support a wide range of business types such as voice, data, audio, video and images. In order to support multiple business types, the next-generation mobile communication system is required to support higher data rates and higher spectral efficiency. And a perfect quality of service (QOS, Quality Of Service) guarantee mechanism to provide better mobility support and seamless network coverage, so as to achieve the goal of providing users with communication services anytime and anywhere. [0003] Among them, the second-generation mobile communication uses time division multiple access (TDMA, main...
