Patent number: 9002262Abstract: Methods and systems for extending a bandwidth of a multi-mode wideband antenna of a user device are described. A multi-mode wideband antenna includes a single radio frequency (RF) feed coupled to a first element, and a second element coupled to the first element and a ground plane. The first element is to operate as a feeding structure to a parasitic grounding element that is coupled to the ground plane, but is not conductively connected to the RF feed. The multi-mode wideband antenna is configured to provide multiple resonant modes.Type: GrantFiled: November 26, 2012Date of Patent: April 7, 2015Assignee: Amazon Technologies, Inc.Inventor: Jerry W.

Patent number: 8995921Abstract: A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted consecutively from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.Type: GrantFiled: December 27, 2004Date of Patent: March 31, 2015Assignee: InterDigital Technology CorporationInventors: Ana Lucia Iacono, Arty Chandra, Inhyok Cha, Paul Marinier, Vincent Roy

Patent number: 8995924Abstract: A method for configuring gain factors in a WCDMA telecommunication system is provided in which the gain factor for defining power required for normal reception of uplink data in an environment supporting an uplink service over an E-DCH can be configured using minimal signaling information. First gain factors for first TFs corresponding to a part of a TF set including a plurality of TFs available for an uplink service are received. One of the first TFs is determined as a reference TF for a second TF other than the first TFs in the TF set. Then, a second gain factor for the second TF is calculated using the first gain factor for the determined reference TF. The second gain factor is used for transmitting or receiving uplink data.Type: GrantFiled: March 4, 2013Date of Patent: March 31, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Youn-Hyoung Heo, Ju-Ho Lee, Yujian Zhang, Joo-Young Cho, Young-Bum Kim, Yong-Jun Kwak

Patent number: 8996066Abstract: Methods and apparatus are provided for directing a beam towards a receiving device in the presence of interference. A beam transmitted by a transmission source is received by a received device. The beam shape is affected by signals transmitted by interfering sources. The receiving device computes channel estimates associated with the transmission source and the interfering sources. A feedback signal that represents the channel estimates associated with the transmission and interfering sources is transmitted to the transmission source. The transmission source changes characteristics of the beam to compensate for the interference caused by the interfering sources. The transmission source may change the characteristics of the beam by performing precoding algorithms.Type: GrantFiled: January 30, 2009Date of Patent: March 31, 2015Assignee: Marvell International Ltd.Inventors: Jungwon Lee, Hui-Ling Lou
