Abstract

sistemas e métodos para programação de entrada múltipla e saída múltipla (mimo) de pacote de acesso de enlace descendente de alta velocidade (hsdpa) de canais piloto transição a partir de ordem de base de estimativa mais elevada mimo para o reforço da estimativa mimo de ordem superior (e vice-versa) pode ser realizado através da sinalização de acesso de pacote de enlace descendente de alta velocidade (hsdpa) de canal de controle compartilhado (hs-scch) de ordens para equipamentos de usuário da próxima geração (ues). uma estação de base pode ser configurada para enviar uma ordem hs-scch indicando ativação de canais piloto regular e, em seguida começar a transmitir os canais piloto regular depois de ter recebido uma mensagem de ack de, pelo menos, um ue de última geração. a estação base também pode ser configurada para enviar uma ordem hs-scch indicando desativação de canais piloto programados para ues de próxima geração programados para transmissão de enlace descendente, e depois parar de transmitir os canais piloto programados depois de receber mensagens de confirmação de cada nova geração ue. alternativamente, canais piloto programados podem ser ativados / após a expiração de um período de tempo limite desativado, mesmo sem receber uma mensagem ack de alguns ou de todos os ues de próxima geração programados para transmissão de enlace descendente.
