Abstract

método de alocação de sinal piloto e aparelho para sistemas sem fio de usuário múltiplo. uma construção é fornecida para sinais piloto uplink numa rede celular. três conjuntos de sinais piloto são definidos, tendo propriedades de ortogonalidade que levam interferência intercélula reduzida. em exemplo de modaliadades, a rede tem um fator de reutilização de 3 para sinais piloto, com conjuntos de u, v e w de sinais piloto atribuídas às células em respectivas classes de reutilização. os pilotos de cada conjunto formam uma base otogonal. alguns pilotos de cada classe, isto é, aquela que geralmente será atribuída às estações móveis perto das bordas das células, também irá formar uma base ortogonal com alguns pilotos de cada uma das outras classes.Pilot signal allocation method and apparatus for multiple user wireless systems. One construction is provided for uplink pilot signals in a cellular network. Three sets of pilot signals are defined, having orthogonal properties that lead to reduced intercellular interference. For example, the network has a reuse factor of 3 for pilot signals, with sets of pilot signals u, v and w assigned to cells in their respective reuse classes. the pilots of each set form an otogonal base. Some pilots of each class, that is, the one that will generally be assigned to mobile stations near the edges of the cells, will also form an orthogonal base with some pilots of each of the other classes.
