Patent number: 8565799Abstract: Methods and apparatus for flow data acquisition in a multi-frequency network. In an aspect, a method includes receiving flow registrations associated with flows, assigning a priority to the flow registrations, grouping the flows into flow groups based on their priority and RF channels carrying the flows, wherein each flow group is assigned a ranking, selecting a flow group based on the ranking, and acquiring flow data for the flows associated with the flow group. An apparatus includes registration logic configured to receive flow registrations associated with flows, priority logic configured to assign a priority to the flow registrations, and acquisition processing logic configured to group the flows into flow groups based on their priority and RF channels carrying the flows, wherein each flow group is assigned a ranking, select a flow group based on the ranking, and acquire flow data for the flows associated with the flow group.Type: GrantFiled: March 19, 2008Date of Patent: October 22, 2013Assignee: QUALCOMM IncorporatedInventors: Binita Gupta, An Mei Chen

Patent number: 8559344Abstract: The invention includes a method and apparatus for creating a base station neighbor list at a target base station in a wireless network including a plurality of base stations. A method includes obtaining information for creating the base station neighbor list, creating the base station neighbor list using the obtained information, and storing the base station neighbor list. The obtained information includes at least one of geographic locations of ones of the base stations, network status information associated with the wireless network, and pilot signal strength measurement feedback information. The base station neighbor list includes a subset of the base stations of the network. The base stations of the base station neighbor list may be prioritized using at least a portion of the obtained information. The base station neighbor list may be updated periodically, or in response to changes to the obtained information.Type: GrantFiled: June 29, 2007Date of Patent: October 15, 2013Assignee: Alcatel LucentInventors: David Abusch-Magder, Suman Das, Thierry Etienne Klein, Harish Viswanathan

Patent number: 8559994Abstract: A wireless communication method and system using virtual MIMO (“V-MIMO”) are provided. Post processing signal to interference and noise ratios (“SINR”) for a plurality of signals corresponding to a plurality of mobile terminals arranged as a V-MIMO group are estimated. The one of the plurality of mobile terminals having the highest post processing SINR is selected. Wireless communication for the selected mobile terminal is scheduled. The signal corresponding to the selected mobile terminal is cancelled. Post processing signal to interference and noise ratios (“SINR”) for the signals corresponding to the remaining mobile terminals is re-estimated. The one of the remaining mobile terminals having the highest post processing SINR is selected. Wireless communication for the selected remaining mobile terminal is scheduled.Type: GrantFiled: January 7, 2013Date of Patent: October 15, 2013Assignee: Apple Inc.Inventors: Ming Jia, Jianglei Ma, Jianming Wu, Peiying Zhu, Wen Tong

Patent number: 8554210Abstract: An apparatus for storing handover information in a mobile communication system is provided. The apparatus includes an estimation unit configured to estimate a direction of arrival (DOA) of a received signal with respect to a first base station based on the received signal, the received signal being received from a terminal belonging to the first base station, and a storage unit to store the estimated DOA as handover information associated with a second base station when the terminal is handed over to the second base station.Type: GrantFiled: October 9, 2007Date of Patent: October 8, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Hyun Ho Choi, In Sun Lee, Hyo Sun Hwang, Yoon Chae Cheong, Tae In Hyon, Kyung Hun Jang, Young Soo Kim

Patent number: 8548522Abstract: A multimode communication integrated circuit comprising baseband processing circuitry with a shared radio interface. Various aspects of the present invention may comprise a processor module adapted to perform various processing (e.g., baseband processing) in support of multimode communications. A first radio module may be communicatively coupled to the processor module through a common communication interface. A second radio module may also be communicatively coupled to the processor module through the common communication interface. The common communication interface may, for example, be adapted to communicate information over a communication bus that is shared between the processor module and a plurality of radio modules (e.g., the first and second radio modules).Type: GrantFiled: August 2, 2012Date of Patent: October 1, 2013Assignee: Broadcom CorporationInventor: Jeyhan Karaoguz

Patent number: 8548458Abstract: The present invention relates to the communications field and discloses a method, a device, and a system for measuring and reporting an automatic neighbor relation (ANR), which are capable of completing an ANR function during a radio link failure (RLF), therefore saving measurement time and improving network performance. The solution is: when an RLF occurs, receiving a radio resource control (RRC) link reestablishment failure message, where the RRC link reestablishment failure message carries control information instructing a user equipment (UE) to perform an ANR measurement; performing the ANR measurement according to the control information in the RRC link reestablishment failure message to obtain an ANR measurement result; and after receiving an RRC link establishment response message, reporting the ANR measurement result by using an RRC link establishment complete message.Type: GrantFiled: September 16, 2011Date of Patent: October 1, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Ying Huang, Ping Song

Patent number: 8532686Abstract: A central registration system provides channel maps of available spectrum to radio devices based on feedback and spectrum allocation policies. Each available channel in the channel map is given a score that is indicative of the quality of the channel for use by the particular radio device for which the channel map was generated. The quality score for each available channel may be based on the radio device's susceptibility to different types of interference and/or radio device's tolerance of the different types of potential interference.Type: GrantFiled: December 24, 2010Date of Patent: September 10, 2013Assignee: Spectrum Bridge, Inc.Inventors: Jeffrey C.
