  • Patent number: 8565161
    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.

  • Patent number: 8437416
    Abstract: A reference signal cyclic shift (CS) is quantized as a combination of a cell specific CS with an outcome of a pseudo-random hopping, and an indication of the cell specific CS is broadcast in the cell. In one embodiment the CS is quantized as a modulo operation on a sum of the cell specific CS, the outcome of the pseudo-random hopping, and a user specific CS, in which case an indication of the user specific CS is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The CS may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of CS given in reference signal symbols.
