Abstract

método para alocar recursos de frequência temporal em terminais móveis, ponto de acesso sem fio, método para processar dados recebidos transmitidos por um ponto de acesso, e, terminal móvel sem fio. são descritos métodos para alocar recursos de frequência temporal em terminais móveis em um sistema de comunicações sem fio no qual recursos de frequência temporal podem ser seletivamente usados de acordo com um primeiro esquema de transmissão com múltiplas entradas e múltiplas saídas (mimo) ou com um segndo esquema de transmissão mimo que difere do primeiro esquema de transmissão mimo. um método exemplar compreende, pelo menos para uma primeira instância de agendamento, identificar um primeiro grupo de terminais móveis correspondente ao primeiro esquema de transmissão mimo e um segundo grupo de terminais móveis correspondente ao segundo esquema de transmissão mimo, alocar recursos de frequência temporal em uma primeira zona de frequência temporal predeterminada exclusivamente em terminais móveis que pertencem ao primeiro grupo e alocar recursos de frequência temporal em uma ou mais zonas de frequência temporal predeterminadas adicionadas em um ou mais terminais móveis que pertencem ao segundo grupo. este método pode ser implementado em uma estação base de um sistema wimax, por exemplo.
