Abstract

TRANSMISSÃO DE MÚLTIPLAS ENTRADAS E MÚLTIPLAS SAÍDAS DE UPLINK PREDEFINIDA ANTES DA ATIVAÇÃO DO ESTADO DE INDICAÇÃO DE CONFIGURAÇÃO DE TRANSMISSÃO DE UPLINK. Diversos aspectos da presente revelação, de modo geral, referem-se à comunicação sem fio. Sob alguns aspectos, uma estação base pode transmitir, e um equipamento de usuário (UE) pode receber, informações de controle de downlink (DCI) que programam uma comunicação de uplink de múltiplas entradas e múltiplas saída (MIMO). O UE pode transmitir e a estação base pode receber a comunicação MIMO de uplink que utiliza uma configuração de recurso de sinal de referência sonoro (SRS) predefinido com base, pelo menos em parte, no UE que recebe a DCI antes de um elemento de controle do controle de acesso a meios (MAC) (MAC-CE) selecionar um subconjunto de estados de indicação de configuração de transmissão (TCI) de uplink incluídos em um grupo de estados de TCI de uplink configurados para o UE. Numerosos outros aspectos são fornecidos.
