Patent ID: 7079568

Claim:
A frequency hopping method for a mobile radio system, the mobile radio system having a base station with a carrier frequency and at least one mobile station, each mobile station having a carrier frequency, the method comprising: changing the carrier frequency of the base station and the carrier frequency of at least one mobile station temporally in defined intervals according to a pre-determined frequency hopping scheme; monitoring certain operational conditions of the mobile radio system; providing update information to adapt the frequency hopping scheme to a frequency environment of the mobile radio system; transmitting the update information from the base station to each of the at least one mobile stations via a control channel of the mobile radio system and, further, indicating the carrier frequencies of the frequency hopping scheme to be avoided for the frequency hopping method by each of the at least one mobile stations to each of the at least one mobile stations; and changing the carrier frequencies of the base station and each of the at least one mobile stations according to the pre-determined frequency hopping scheme based on the update information; and whereby the update information for the next n carrier frequencies according to the pre-determined frequency hopping scheme of the at least one mobile station indicates whether or not the corresponding carrier frequency for the frequency hopping method should be used, or all carrier frequencies available for the frequency hopping method are combined in several frequency groups, whereby the update information indicates for each of these frequency groups whether or not the carrier frequencies belonging to the particular frequency group should be used for the frequency hopping method.
