Abstract

a presente invenção refere-se a alinhamento de símbolo e escalonamento de potência para intervalos de tempo de transmissão (ttis) de diferentes comprimentos dentro de limites predefinidos, tais como limites de uma partição de um subquadro. as técnicas descritas proveem identificação de recursos de tempo e/ou frequência para um ou mais ttis e alocação de tais recursos com base em uma localização dentro de um subquadro, sinais piloto que podem ser transmitidos usando os recursos, outros cronogramas de processamento, ou qualquer combinação desses. em alguns casos, uma alocação de potência para símbolos dentro de um tti pode ser determinada com base nos recursos alocados para o tti. padrões de salto de frequência e escalonamento de potência para ttis de três símbolos são também providos.
