    • The present invention provides a method and apparatus for allocating feedback transmission resource and a method and apparatus for providing information on values thereof. According to the method of allocating feedback transmission resource, the feedback transmission resource is divided into a plurality of resource units, and the method can comprise receiving information on values of the plurality of resource units for the mobile stations; determining values of possible resource allocation status in each bidding round for the mobile stations from the received information on the values based on the sequential second price auction; and deriving an auction process of the resource units from the determined values of possible resource allocation status in each bidding round based on the sequential second price auction, so as to obtain a final resource unit allocation result for the mobile stations. With embodiments of the present invention, it is possible to improve performance in sum channel capacity and at the same time it can achieve preservation in fairness among MSs. In preferred embodiments of the present invention, the feedback transmission resource can be optimized between at least two kinds of feedback information such as channel station information and intercell interference information, which will further improve the system performance.
    • 本发明提供了一种用于分配反馈传输资源的方法和装置,以及用于提供关于其值的信息的方法和装置。 根据分配反馈传输资源的方法,将反馈传输资源划分为多个资源单元,该方法可以包括接收关于移动站的多个资源单元的值的信息; 根据所接收到的信息,根据连续的第二价格拍卖,确定移动台每个出价轮次中可能的资源分配状态的值; 以及根据所述连续的第二价格拍卖,根据所述每个出价回合中的所述资源分配状态的确定值,得出所述资源单元的拍卖处理,以获得所述移动台的最终资源单位分配结果。 利用本发明的实施例,可以提高和信道容量的性能,同时可以在MS之间实现公平的保护。 在本发明的优选实施例中,可以在诸如信道站信息和小区间干扰信息的至少两种反馈信息之间优化反馈传输资源,这将进一步提高系统性能。
