Abstract

a presente invenção refere-se a métodos, sistemas, e dispositivos para comunicação sem fio. uma estação de base pode transmitir uma indicação de primeira e segunda configurações para transmissões de sinal de referência sonoro (srs) durante primeiro e segundo intervalos de tempo de transmissão (ttis) tendo diferentes durações. um equipamento de usuário (ue) pode identificar um srs a ser transmitido e determinar uma configuração para a transmissão de srs com base na duração de tti e na indicação recebida da primeira e segunda configurações. o ue pode, então, transmitir o srs com base na configuração. uma estação de base pode receber um srs durante um tti e pode determinar uma qualidade de canal com base, pelo menos em parte, no srs. adicionalmente, um dispositivo pode identificar dados para transmitir durante um tti, determinar um número de elementos de recurso disponíveis para transmissão dos dados durante um tti e determinar um tamanho de bloco de transporte (tbs) para a transmissão de dados com base nos elementos de recurso disponíveis.
