摘　　要：文中针对B3G系统,提出了一种控制信令传输方法,为了提高传输的可靠性,将空时频编码引入到控制信令的传输中,使得控制信令在传输的过程中,能够同时获得空间分集、时间分集和频率分集,从而达到了提高传输可靠性的目的。最后,对提出的方案进行了仿真,并与3GPPLTE进行了对比,仿真结果表明,采用该方案能够获得更好的性能。In view of Beyond 3G mobile communication system, this paper proposes a new design method for transmitting control signal. In order to enhance the transmission reliability, the space-time-frequency code is introducedinto the process of transmitting control signal, thus to make the control signal achieve space diversity gain, time diversity gain and frequency diversity gain simultaneously. Finally, this paper describes the simulation on the proposed method and the comparison with 3GPP LTE system. The results indicate that the proposed method can obtain better performance.
