Patent number: 8831690Abstract: A method for communication includes modulating data in a wireless communication terminal to produce an aggregated-spectrum signal, which includes multiple component carriers in multiple respective spectral bands, each component carrier including a respective plurality of sub-carriers in respective frequency bins, wherein the component carriers are grouped in one or more groups. The modulated data in transmitted on the multiple component carriers at respective power levels. A single instruction, to set a power level of the component carriers in a given group, is received at the wireless communication terminal. The power level of the component carriers in the given group is set based on the single instruction, and while preserving relative power ratios among the sub-carriers within each of the component carriers.Type: GrantFiled: November 6, 2012Date of Patent: September 9, 2014Assignee: Marvell World Trade Ltd.Inventors: Yona Perets, Ezer Melzer, Itsik Bergel

Patent number: 8670719Abstract: A method for communication includes receiving at a receiver from a group of two or more transmitters multiple Radio Frequency (RF) transmission beams that alternate in time and space and include at least first and second transmission beams. The method identifies that the first transmission beam causes interference to reception of the second transmission beam. Feedback is sent from the receiver to one or more of the transmitters, so as to cause the transmitters to attenuate the first transmission beam during transmission of the second transmission beam.Type: GrantFiled: September 17, 2013Date of Patent: March 11, 2014Assignee: Marvell World Trade Ltd.Inventors: Itsik Bergel, Shlomo Shamai, Daniel Yellin, Yona Perets

Patent number: 8644236Abstract: A method for communication includes providing a first transceiver configured to communicate with a second transceiver over a bi-directional link having a first aggregation of frequencies that are assigned to carry first communication traffic in a first link direction from the first transceiver to the second transceiver and a second aggregation of frequencies that are assigned to carry second communication traffic in a second link direction from the second transceiver to the first transceiver. Communication feedback is transmitted from the first transceiver to the second transceiver communication feedback at an adaptive feedback rate. The feedback rate is determined so as to achieve a desired balance between the information carrying capacities of the first and second aggregations. An information carrying capacity of the second aggregation is controlled responsively to the communication feedback.Type: GrantFiled: August 7, 2011Date of Patent: February 4, 2014Assignee: Marvell World Trade Ltd.Inventors: Daniel Yellin, Yona Perets, Itsik Bergel

Patent number: 8320977Abstract: A method for communication includes modulating data in a wireless communication terminal to produce an aggregated-spectrum signal, which includes at least first and second signals in respective first and second spectral bands. The modulated data is transmitted in the first and second signals at respective first and second power levels. The second power level is adjusted separately from the first power level. In some embodiments, one or more instructions to set the first power level are received at the wireless communication terminal, and the first power level is set separately from setting the second power level based on the instructions.Type: GrantFiled: February 19, 2012Date of Patent: November 27, 2012Assignee: Marvell World Trade Ltd.Inventors: Yona Perets, Ezer Melzer, Itsik Bergel

Publication number: 20110286371Abstract: A method for communication includes providing a first transceiver configured to communicate with a second transceiver over a bi-directional link having a first aggregation of frequencies that are assigned to carry first communication traffic in a first link direction from the first transceiver to the second transceiver and a second aggregation of frequencies that are assigned to carry second communication traffic in a second link direction from the second transceiver to the first transceiver. Communication feedback is transmitted from the first transceiver to the second transceiver communication feedback at an adaptive feedback rate. The feedback rate is determined so as to achieve a desired balance between the information carrying capacities of the first and second aggregations. An information carrying capacity of the second aggregation is controlled responsively to the communication feedback.Type: ApplicationFiled: August 7, 2011Publication date: November 24, 2011Inventors: Daniel Yellin, Yona Perets, Itsik Bergel
