摘要
The invention relates to a Method, a Communication System and an Communication Unit for protecting incumbent services whereas in the incumbent services first information is exchanged between first communication means by radio frequency transmission within a first bandwidth using a first protocol and second information is exchanged between second communication means by radio frequency transmission within a second bandwidth using a second protocol and the second bandwidth is overlapping and larger than the first bandwidth. The problem to be solved is to reduce or to eliminate an interference of secondary services to incumbent services. The problem is solved by ascertaining the presence of any first information exchange between said first communication means; transmitting a protecting information at least about the presence of a first information exchange to at least one of the second communication means; inhibiting said at least one of the second communication means to use the radio frequencies used for exchanging the first information for transmitting the second information and transmitting the second communication within a frequency range wherein the radio frequencies used for exchanging the first information for transmitting the second information are notched.
