Abstract

técnicas para utilizar recursos em uma rajada comum downlink (dl) são descritas na presente invenção. em um aspecto, um sinal de referência de informação de estado de canal (csi-rs) pode ser incluído na rajada comum dl para estimação de canal. em outro aspecto, um sinal de referência de demodulação (dm-rs) e dados dl podem ser incluídos na rajada comum dl para transmissão de dados de latência baixa. ainda em outro aspecto, um sinal de referência de medição (m-rs) pode ser incluído na rajada comum dl para auxiliar decisões de handover. as técnicas descritas aqui podem ser usadas para vários sistemas de comunicação sem fio.
