信息技术系统间远程通信和信息交换局域网和城域网特定要求第22部分:认知无线RAN媒体访问控制（MCA）和物理层（PHY）规范:电视频段操作的策略和程序

[中文适用范围]： 该标准规定了由专业固定基站（BS）组成的点对多点无线区域网络（WRAN）的空中接口，包括认知媒体访问控制层（MAC）和物理层（PHY）。固定和便携式用户终端在 54 MHz 至 862 MHz 之间的 VHF/UHF 电视广播频段运行，并且可能在 1300 MHz 至 1750 MHz 频段运行，... [外文原描述]： This document specifies the air interface, including the cognitive radio medium access control layer (MAC) and physical layer (PHY), of point-to-multipoint and backhaul wireless regional area networks (WRANs) comprised of a professional fixed base station (BS) with fixed and portable user terminals. The document specifies operation in the bands that allow spectrum sharing where the communications devices may opportunistically operate in the spectrum of the primary service, such as the VHF/UHF TV broadcast bands between 54 MHz to 862 MHz, and the 1300 MHz to 1750 MHz and 2700 MHz to 3700 MHz bands provided the regulatory regime allows it.
