20100232387 | METHOD FOR OPTIMIZING THE TRIGGERING OF THE TRANSMISSION OF BUFFER STATUS REPORTING (BSR) INFORMATION - The invention concerns a method for optimizing the transmission of Buffer Status Reporting (BSR) information from a User Equipment (UE) to a Base Station (BS) in a wireless telecommunication network wherein the transmission of Buffer Status Reporting information is triggered if new uplink data arrive in the UE transmission buffer of said UE and said new uplink data belong to a logical channel for which a positive PBR (Prioritized Bit Rate) parameter is defined and for which no data already existed in the UE transmission buffer. | 09-16-2010 |
20120282926 | WIRELESS COMMUNICATION APPARATUS FOR COMMUNICATING WITH A MOBILE STATION - A wireless communication apparatus for communicating with a mobile station in a cell covered by at least one Radio Access Technology (RAT) and frequency, wherein the cell including a plurality of meshes, and a mobile station having various RAT capabilities and supporting several frequencies, wherein the wireless communication apparatus characterized by transmitting a first beacon having first information related to all RAT's and frequencies which the mobile station can use in the cell and, transmitting a second beacon having second information which shows availability in one of a plurality of meshes for each RAT and frequency included in the first beacon. | 11-08-2012 |
20130010738 | METHOD FOR OPTIMIZING THE TRIGGERING OF THE TRANSMISSION OF BUFFER STATUS REPORTING (BSR) INFORMATION - A method, performed by a user equipment (UE), for transmitting Buffer Status Reporting (BSR) information from the UE to a base station (BS) in a wireless telecommunication network, includes storing data to be transmitted, via a logical channel, in a transmission buffer, the logical channel being provided with a priority level and a specific Prioritized Bit Rate (PBR) parameter indicating a resource level to allocate to the UE for transmitting the stored data, wherein the BSR information represents an amount of data present in the transmission buffer of the UE, receiving new uplink data belonging to a logical channel for which no data already existed in the UE transmission buffer, and transmitting Buffer Status Reporting information upon receipt of the new uplink data. | 01-10-2013 |
20130120390 | SYSTEMS AND METHODS FOR RENDERING A DISPLAY TO COMPENSATE FOR A VIEWER'S VISUAL IMPAIRMENT - A system and method is provided for rendering on a display of an electronic device a pre-corrected image of an original image to compensate for a visual impairment of a user of the device, such that the pre-corrected image when displayed on the display would be perceived by the user to be in better optical focus than the user would perceive a display of the original image. The method includes receiving hardware characteristics of the display, receiving at least one parameter describing the visual impairment of the user, receiving at least one parameter describing the conditions under which the display is seen by the user, calculating a pupil function, calculating a Point Spread Function (PSF), calculating a pre-corrected image corresponding to at least a portion of the original image to compensate for the visual impairment of the user, and rendering on the display the pre-corrected image. | 05-16-2013 |
