摘要： An apparatus and method are disclosed for determining the optimal bandwidth fractions for all the users in each frequency band in a wireless communication system to maximize the net sum of user utilities. User utilities are functions of average rates of users, where different averaging rules can be used for different users. The standard approach of computing an optimal scheduler strategy involves the solution of a convex optimization problem that has a complexity on the order of O(N3) for N flows. This approach is not feasible for online implementation having a large number of flows. The method of the present work employs an efficient computational algorithm that obtains the optimal bandwidth fractions in O(N) time. This feature makes the method suitable for implementation in wideband cellular systems like LTE (Long Term Evolution) and UMB (Ultra Mobile Broadband).

摘要： Disclosed are methods and apparatus for synchronizing tile processing and assignment processing in a communication device. In particular, the methods and apparatus utilize a tile processing scorecard with a number of assertable bits corresponding to a number of tiles to be tile processed. As each tile is tile processed, the scorecard or bit indicators are asserted to indicate that the tile has been processed. Assignment jobs, which involve codewords having information from symbols in multiple tiles are processed after all of the pertinent tiles are tile processed. The scorecard information is accessible for assignment processing to determine which tiles have been processed, thus affording synchronization of tile processing with assignment processing, while maximizing the independence of these two processing operations. Tile processing operations may further use the scorecard information to prioritize or order tile processing in relation to known queued assignment jobs.
摘要翻译：公开了用于在通信设备中同步瓦片处理和分配处理的方法和装置。特别地，所述方法和装置利用具有对应于要被瓦片处理的瓦片的数量的多个可断言位的瓦片处理记分卡。当每个瓦片被瓦片处理时，记分卡或位指示器被断言以指示瓦片已被处理。分配作业涉及具有来自多个瓦片中的符号的信息的码字，在所有相关瓦片被瓦片处理之后被处理。记分卡信息可被访问用于分配处理以确定已经处理了哪些瓦片，从而提供瓦片处理与分配处理的同步，同时最大化这两个处理操作的独立性。平铺处理操作可以进一步使用记分卡信息来对已知的排队分配作业进行优先排序或排序瓦片处理。
