摘要： Method of arranging a cellular radio network in a geographical area which is already covered by an existing cellular radio network, wherein cell clusters of the cellular radio network to be introduced and using a specific transmission frequency are located in areas determined by connecting at least two cells of the existing cellular radio network using the specific transmission frequency, and wherein the cell clusters are arranged such that they do not overlap with the cells of the existing cellular radio network. The cell clusters of the introduced cellular radio network may be adjusted by reducing the cell size of cell clusters of the introduced cellular radio network, and by introducing new cells into cell clusters of the introduced cellular radio network. The invention allows to reuse frequencies of an existing cellular radio network by an introduced cellular radio network in the same geographical area.

摘要： In wireless telecommunications systems, such as wireless local area networks, a flexible, less complex, and bandwidth efficient forward error correction method can be achieved by applying a first convolutional coding scheme to the bits in a first portion of a data block and a second convolutional coding scheme to the bits in a second portion of the data block, wherein the second portion of the data block may encompass a remaining portion of the data block, excluding the first portion, or the entire data block, including the first portion. While the first coding scheme employs a first code rate, the second coding scheme employs a second code rate that is higher than the first code rate. The higher rate makes it possible to incorporate the one or more tail bits into the second portion of the data block, and therefore, avoid generating any additional symbols, such as orthogonal frequency division multiplexing symbols, to exclusively modulate the tail bits.

摘要： A technique for determining a frequency offset between components of a communication network based on a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence is described. A method implementation of this technique comprises a provision of a set of correlation signals at different frequencies, with each correlation signal being indicative of a specific frequency offset hypothesis and comprising the CAZAC sequence. Once a synchronization signal comprising the CAZAC sequence is received, this synchronization signal is correlated with each of the correlation signals to obtain a correlation result for each frequency offset hypothesis. In a next step, at least one of the frequency offset hypotheses is selected based on a comparison of the correlation results. The frequency offset may then be determined based on the at least one selected frequency offset hypothesis.
