Abstract

a descrição refere-se em alguns aspectos às técnicas para estimativa aperfeiçoada de canal. por exemplo, um dispositivo pode especificar uma estrutura piloto onde a densidade piloto difere com o tempo. como outro exemplo, um dispositivo pode indicar que um piloto de um intervalo de tempo de transmissão anterior (tti) pode ser utilizado para a estimativa de canal. como outro exemplo, um dispositivo pode empregar o enfeixamento de bloco de recurso físico de domínio de frequência (prb) com a sinalização de informação de enfeixamento. como outro exemplo, um dispositivo pode utilizar uma razão de tráfego para piloto (tpr) ajustável para a otimização de rendimento. outros aspectos, modalidades e características também são discutidas e reivindicadas.
