Method for controlling a radio transmission
View Patent ↗At least one radiation pattern is rotated at a first radio station for the purpose of sampling a predefined angular range. At a first time of rotation, a second radio station is detected with a first angular position within the angular range corresponding to the first time. The second radio station determines a first quality value which can be assigned to the first angular position and reports the first quality value back to the first radio station. The first quality value is available for evaluation at the first radio station at a second time corresponding to a second angular position of the radiation pattern. The first radio station controls the speed of rotation of the at least one radiation pattern for subsequent rotations so that the first angular position corresponds to the second angular position.
1. A method for controlling a radio transmission between radio stations, comprising:
rotating at least one radiation pattern of a first radio station for sampling over a predefined angular range;
detecting a second radio station at a first time of said rotating of the at least one radiation pattern, the first time corresponding to a first angular position within the predefined angular range;
determining at the second radio station a first quality value which can be assigned to the first angular position;
reporting back the first quality value to the first radio station to make the first quality value available for evaluation at the first radio station at a second time corresponding to a second angular position of The at least one radiation pattern; and
controlling at the first radio station a speed of rotation of the at least one radiation pattern for subsequent rotations so that the first angular position corresponds to the second angular position.
2. The method as claimed in claim 1 , wherein said rotating uses a plurality of radiation patterns simultaneously for sampling the predefined angular range.
3. The method as claimed in claim 2 , wherein the speed of rotation of the plurality of radiation patterns is a function of predefined sub-areas of the angular range.
