Latest Patent Applications

Kari Leppänen has been involved in several innovative patent applications. One of her latest applications is titled "Method and Arrangement for Determining at Least One Distance Between Antennas." This method includes performing self-measurements and first two-way transmissions at first time intervals, first one-way transmissions at second time intervals, second two-way transmissions at third time intervals, and second one-way transmissions at fourth time intervals. The method also encompasses determining phase information based on the performed transmissions and ascertaining distance information regarding the at least one distance.

Another significant application is "Method and Arrangement for Performing Radio Transmissions." This method involves assigning radio units to one subgroup of first radio units and another subgroup of second radio units. It also includes assigning a signal frequency set to each subgroup of first radio units and a signal frequency subset in a signal frequency set of a subgroup of first radio units to each second radio unit in a subgroup of second radio units associated with the subgroup of first radio units. The method ensures that signal frequency subsets assigned to each second radio unit in the same subgroup of second radio units differ from each other in at least one measurement frame.
