Abstract

de acordo com algumas modalidades, um método para uso em um nó de rede de transmissão de sinais de referência de informação de estado de canal (csi-rs) compreende: transmitir, para o dispositivo sem fio, uma indicação do subconjunto de prbs que o dispositivo sem fio deve usar para medir csi-rs; e transmitir csi-rs no subconjunto indicado de prbs. de acordo com algumas modalidades, um método para uso em um dispositivo sem fio de recepção de csi-rs compreende: receber uma indicação de um subconjunto de prbs que o dispositivo sem fio deve usar para medir csi-rs associado a uma porta de antena; e receber csi-rs no subconjunto indicado de prbs. em algumas modalidades, a indicação do subconjunto de prbs que o dispositivo sem fio deve usar para medir csi-rs compreende um valor de densidade e um deslocamento de pente.
