Patent number: 9106392Abstract: Transmission antenna diversity can be set up on a data transmission connection between a transmitting unit, wherein there are several transmission antenna routes, and a receiving unit. A broadcast signal is transmitted through all transmission antenna routes of the transmitting unit, with the aid of these signals a choice is made in the receiving unit of the optimum transmission antenna route and a message of the choice is transmitted to the transmitting unit, which transmits user data through the transmission antenna route connected for use. The broadcast signal of each transmission antenna route can be shaped by an individual signal shaping method which is different from the others and a transmission antenna route is connected for use based on the received antenna choice message, individually for each receiving unit.Type: GrantFiled: November 29, 2006Date of Patent: August 11, 2015Assignee: NOKIA TECHNOLOGIES OYInventors: Ari Hottinen, Risto Wichman

Patent number: 8909270Abstract: A method, apparatus, and computer program for cognitive radio communications are provided. A reference signal is received from a transmitter of a primary system, and the received reference signal is received with an arbitrarily selected beamforming setting. Then, a signal quality metric is calculated from the received and beamformed reference signal. If the signal quality metric indicates that a reception power of the received signal is low, transmission of a data signal to a wireless communication device of a secondary system is scheduled. In the scheduled transmission in the secondary system, the same beamforming setting as was used in the reception of the reference signal is employed.Type: GrantFiled: June 23, 2010Date of Patent: December 9, 2014Assignee: Nokia CorporationInventor: Ari Hottinen
