METHOD AND APPARATUS FOR PROTECTING A PRIMARY SERVICE IN WLAN SYSTEM |
摘要 |
A method and an apparatus for protecting a primary service as an unlicensed device in a regulatory domain where a licensed device and the unlicensed device are permitted to operate are disclosed. For protecting a primary service by a station as an unlicensed device in a regulatory domain where a licensed device and the unlicensed device are permitted to operate, the unlicensed device acquires a list of identified available channels for the operation of the unlicensed device and maximum allowed transmission powers of the identified available channels from a regulatory domain database system; generates a white space map (WSM) comprising the list of identified available channels and the maximum allowed transmission powers of the identified available channels; updates the WSM when the station acquires information that a primary service signal is detected on a specific channel which is indicated as available in the WSM; and transmits the updated WSM to another station such that the another station moves to another channel if the another station is operating on the specific channel. |
