Patent number: 8819806Abstract: An application portal selectively provides a user selective access to data. A data access layer is included in the portal and includes a map associating the user with a permission and further associating a combination of the user and the permission with a data entity, whereby it may be determined whether the user is permitted to access data identified with the data entity. A data stage included in the portal selectively undergoes a synchronization with a remote data store, the synchronization providing data access information that is used to update the map.Type: GrantFiled: October 20, 2006Date of Patent: August 26, 2014Assignee: Verizon Patent and Licensing Inc.Inventors: Chi-Hwei Julie Lin, Tsehsin Jason Liu, Wei Miao, Yunyan Wang

Patent number: 8761288Abstract: A multiuser downlink multiple-input multiple-output (MIMO) system with limited channel information feedback includes an error-free channel vector quantization scheme. Each user has multiple antennas, and the base station includes a matching number of antennas. Each MIMO channel is measured at the terminus end of a corresponding user, and used to obtain the channel state information at the receiver (CSIR). A few data bits of CSIR information are feed back to the base station through the limited feedback channels. The base station collects all these CSIR feedback data bits into a CSI at the transmitter (CSIT). The CSIT is used to determine which users are served, and how to configure a corresponding multi-user precoder. The user data channels will later all be transmitted through such precoder. A codebook of channel quantization vectors is pre-defined and distributed amongst the base station and all the users.Type: GrantFiled: February 26, 2009Date of Patent: June 24, 2014Assignee: NXP, B.V.Inventors: Wei Miao, Min Huang, Shindong Zhou, Gang Wu
