三网融合与基于协作的无线技术

无线协作技术,特别是立体化的协作架构,有助于广播网和无线通信网更紧密地协同。文章认为无线协作技术提供初级回程通道。它可以通过统一的资源管理,互相配合,提供网络级自动重发请求（ARQ）以及面向用户与业务特性的特色传输。无线协作技术还通过协作中继,提升覆盖质量,实现更紧密的动态频谱共享。紧密地协作将为三网融合提供更有效的协作机制,为用户带来新的业务体验,更好地满足新业务和用户需求的多样化发展。

Cooperative Wireless Technologies in Tri-Network Convergence

Cooperative wireless technology,especially cross-layer cooperative architecture,will contribute to tri-network convergence.This paper proposes cooperative technology that provides primary return channel and network-level automatic repeat request(ARQ) as well as user and service-oriented transmission by means of unified resource management and coordination.Cooperative technology improves coverage quality and allows for dynamic spectrum sharing through cooperative relay.It also provides a more effective coord...
