Abstract

"DESLOCAMENTOS TEMPORAIS PARA CóDIGOS CURTO NUM SISTEMA CDMA". Uma rede de comunicações celulares CDMA (400, Fig. 4) inclui uma ou mais aeronaves (410) que retransmitem sinais de canal piloto e canal de controle entre estações transceptoras base (BTSs 406, 413) e unidades de assinante (403) . Através do canal de controle, a BTS transmite uma lista de candidatas ao hand-off para as unidades de assinante. A lista de candidatas ao hand-off identifica as BTSs candidatas para as quais a unidade de assinante pode, teoricamente, fazer o hand-off. Além disso, a lista indica em quais deslocamentos as unidades de assinante devem procurar por códigos curtos transmitidos pelas BTSs candidatas através do canal piloto. Com base no comprimento do percurso entre a BTS, a aeronave e a unidade de assinante, as BTSs candidatas geram seus códigos curtos em um deslocamento que é igual ou anterior ao deslocamento informado à unidade de assinante por algum delta. Além disso, as BTSs podem impor um atraso variável aos bits de código curto para compensar as variações na demora do percurso à medida que a aeronave prossegue em seu plano de vóo.
