Patent ID: 8179865

Claim:
A transmission method for reducing other cell interference in a wireless communication system, comprising: generating, at a Base Station (BS), at least one modulation symbol to be transmitted; repeating, mapping, and assigning the modulation symbol, at the BS, into a resource block common to the BS and at least one neighboring BS, the at least one neighboring BS being substantially adjacent to the BS, and the resource block comprising a plurality of subcarriers or a plurality of time intervals, wherein the modulation symbol is repeated according to repetition number R such that the modulation symbol can be assigned to each of the plurality of subcarriers or each of the plurality of time intervals; and spreading the mapped modulation symbol, at the BS, with a BS-specific code allocated to the BS, the BS-specific codes of the BS being one of orthogonal and quasi-orthogonal to a BS-specific code allocated to the neighbor BS.
