    Abstract: Backhaul traffic reliability is improved in unlicensed spectrum bands by using cross-protocol channel sensing and reservation. Physical carrier sensing may be employed to scan channel quality of a plurality of carriers of an unlicensed spectrum band and select a carrier for use in a wireless backhaul communications link between a first base station and a second base station based on the scanned channel quality. The described features may further include the first base station transmitting a self-addressed reservation frame on the selected first carrier prior to transmission of backhaul data from the first base station to the second base station over the first carrier.

    Abstract translation: 通过使用交叉协议信道感测和预留，在非许可频谱带中回传业务可靠性得到改善。 可以采用物理载波感测来扫描非许可频谱带的多个载波的信道质量，并且基于扫描的信道质量来选择用于第一基站和第二基站之间的无线回程通信链路中的载波。 所描述的特征可以进一步包括第一基站在通过第一载波从第一基站传输到第二基站的回程数据之前，在所选择的第一载波上发送自寻址预留帧。
