Abstract
<B>UM PROTOCOLO DE ACESSO MúLTIPLO ASSIMéTRICO PARA UM SISTEMA DE COMUNICAçãO<D>. A invenção refere-se a sistemas de comunicação celular móveis nos quais é provido acesso assimétrico a um canal de comunicação dúplex de divisão de tempo (TDD). O canal é dividido (pelo TDD) em espaços que são alocados quer seja para comunicação de ligação ascendente ou para comunicação de ligação descendente pela estação de base em cada célula. A sincronização dos espaços, e dessa forma dos espaços de ligação ascendente e de ligação descendente compulsórios, é coordenada através das células de um sistema.
