Abstract: First information is detected in a received wideband signal. The first information is conveyed by a plurality of multiplexed frequency bands, individual ones of the multiplexed frequency bands corresponding to individual ones of first users and to a transport format. Detecting includes making data decisions corresponding to the first information. For each first user, a regenerated signal is created using the data decisions corresponding to that first user and the transport format. A resultant signal is created based on the regenerated signals for all of the first users and on the received wideband signal. Second information is detected in the resultant signal at least by using a number of spreading codes, individual ones of which are associated with individual ones of second users.

Abstract: The present invention relates to a method and system for transmitting data in cellular network, wherein frequency reuse is proposed to be designed adaptive and utilized only only when needed, e.g., with small coding rates. The adaptive reuse can be obtained by using the conventional link adaptation approach. The invention can be easily applied to a Frequency Division Multiple Access (FDMA) system which consists of combination of localized and distributed FDMA. Thereby, better resistance against strong other cell interference can be provided.
