Abstract

An air interface for use in high throughput digital cellular networks is presented. The design of the interface is one of the contributions to the multidisciplinary Mobile Multimedia Communications (MMC) project at Delft University of Technology. The targets include 155 Megabit per second sustained throughput for high-level users, support for inexpensive mobile stations and support for the Internet protocol (IP), as well as an option for asynchronous transfer mode (ATM). The design consists of an hierarchical frame structure that employs a combination of frequency division multiplexing (FDM) and time division multiplexing (TDM). A comparison is made with the published results of two other research projects, namely MBS (Mobile Broadband Systems) and Median. A protocol is presented that allows transport of control information and data over this link. This protocol features automatic repeat request (ARQ), support for multiple qualities of service (QoS) and graceful degradation of service quality when the load becomes higher than the capacity. A detailed description of the implementation is given.

用于微波频率上的高带宽蜂窝式数字通信的空中接口

提出了一种用于高吞吐量数字蜂窝网络的空中接口。该接口的设计是代尔夫特理工大学多学科移动多媒体通信(MMC)项目的贡献之一。目标包括为高级用户提供每秒155兆比特的持续吞吐量，支持廉价的移动站，支持互联网协议(IP)，以及异步传输模式(ATM)选项。该设计由采用频分复用(FDM)和时分复用(TDM)相结合的分层帧结构组成。并与另外两个已发表的研究项目MBS(移动宽带系统)和Median的结果进行了比较。提出了一种允许在此链路上传输控制信息和数据的协议。该协议具有自动重复请求(ARQ)、支持多种服务质量(QoS)以及当负载超过容量时服务质量的优雅降级等特点。给出了实现的详细描述。
