摘要： 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.

摘要： An apparatus and method for wireless devices have a scalable bandwidth allocation for operating in different bands at different data rates and provide interference prevention between co-existing modes of operation. MAC frame logic selectively defines first characteristics of a first operational mode corresponding to a first wireless link type and second characteristics of a second operational mode corresponding to a second wireless link type. Interference detecting logic detects interference conditions in the first wireless link type and allocates suitable areas for operation of the second wireless link. The same principle used in scaling WLAN to WPAN operation, can also be applied at the lower bit rate of WRAN, in which case a larger range is achieved using a narrower bandwidth and lower a clock rate.
