backward compatibility
后向兼容
Backward compatibility with legacy devices may be enabled at the physical (PHY) layer. At the PHY layer, backward compatibility is achieved by re-using the PHY preamble from a previous standard. Legacy devices may decode the preamble portion of all signals, which provides sufficient information for determining that the wireless channel is in use for a specific period of time, to avoid interference and collisions even though the legacy devices cannot fully demodulate or decode the transmitted frame(s).
由以上可见，演进网络对于现有网络的后向兼容能力的高低也是一个重要的技术指标。[...] 现有技术并未解决演进网络对于 UMTS 网络的后向兼容性问题，无法实现保持 UE 在演进网络和 2G/ 3G 网络间移动时业务的连续性， 也无法实现各种相应的业务流程，比如 UE 附着到 eMSC、idle 状态下移动性管理以及去附着等，而这势必会影响到运营商网络的部署和用户业务的使用。
