    • The present invention provides methods and apparatuses for utilizing unused portions of an allocated frequency spectrum in a wireless communications system that broadcasts content to wireless stations. A first wireless station may communicate with a second wireless station on an idle broadcast channel while keeping the resulting interference level below an acceptable maximum limit at the other wireless stations. Using interference level information that are measured at the wireless stations, the wireless station can negotiate with the other wireless station on an establishment channel for subsequent communications on one or more broadcast channels. The wireless station may receive broadcast content on a time slice that corresponds to a broadcast channel and that is further processed by the wireless station. Otherwise, the wireless station can utilize the corresponding time to measure an interference level for the corresponding channel or to transmit or receive data to/from another wireless station.
    • 本发明提供了在将内容广播到无线站的无线通信系统中利用已分配频谱的未使用部分的方法和装置。 第一无线站可以在空闲广播信道上与第二无线站进行通信,同时将所产生的干扰等级保持在其他无线站的可接受的最大限制之下。 使用在无线站测量的干扰等级信息,无线站可以在建立信道上与另一无线站进行协商,以便在一个或多个广播信道上进行随后的通信。 无线站可以在对应于广播信道的时间片上接收广播内容,并且由无线站进一步处理。 否则,无线站可以利用相应的时间来测量相应信道的干扰电平或者向另一个无线站发送或接收数据。
