Patent number: 9572147Abstract: A method for communicating data between a base station and a terminal device in a wireless telecommunications system, for example an LTE-based system. The wireless communication system uses plural frequency sub-carriers spanning a system frequency band. Physical-layer control information for the terminal device is transmitted from the base station using sub-carriers selected from across the system frequency band, for example to provide frequency diversity. However, higher-layer data for the terminal device is transmitted using only sub-carriers selected from within a restricted frequency band which is smaller than and within the system frequency band. The terminal device is aware of the restricted frequency band, and as such need only buffer and process data within this restricted frequency band during periods where higher-layer data is being transmitted. The terminal device buffers and processes the full system frequency band during periods when physical-layer control information is transmitted.Type: GrantFiled: December 17, 2012Date of Patent: February 14, 2017Assignee: SCA IPLA HOLDINGS INCInventor: Martin Beale

Patent number: 9525635Abstract: In a network communication apparatus, transfer and discard processing is realized for each transfer frame having a priority, and a band limitation is carried out to prevent the congestion of a transfer destination apparatus. Specifically, a bucket is provided for every priority, and tokens of an amount determined based on the priority are supplemented. Moreover, before a bucket evaluation, one shared bucket is provided. All of the tokens existing in the bucket provided for every priority are transferred to the shared bucket for every constant period. The tokens overflowing beyond a capacity of the shared bucket are discarded. All of the frames are equally evaluated and transferred regardless of the priority of each of the frames, as far as the token exists in the shared bucket. When there is no token in the shared bucket, switching to the preferential band limitation is carried out and each priority bucket is evaluated.Type: GrantFiled: November 15, 2012Date of Patent: December 20, 2016Assignee: NEC CorporationInventors: Shihomi Matsumura, Masanori Takashima, Yoji Suzuki

Patent number: 9420347Abstract: A method for video playback switching in response to changing network conditions. The method includes accessing a server to retrieve respective index files for a low bit rate version and a high bit rate version of the video file, and instantiating a low bit rate media player and a high bit rate media. Playback of the video file is begun by the high bit rate media player streaming the high bit rate version from the server. Upon an indication of impeded network conditions, a transition point is selected, wherein the transition point indicates where downloading of the high bit rate version stops and where downloading of the low bit rate version begins. The low bit rate media player is then positioned to begin playback at the transition point. Playback of the video file is then switched to the low bit rate player upon encountering the transition point.Type: GrantFiled: December 26, 2012Date of Patent: August 16, 2016Assignee: Microsoft CorporationInventors: Gilles Khouzam, Donald Karlov, Wenbo Zhang, Federico Schliemann, Sam George, Mike Harsh
