Abstract

um ue transmissor em um comunicação dispositivo a dispositivo (d2d) pode identificar uma sequência de sinal de referência de desmodulação (dmrs) para uma transmissão d2d com base, pelo menos em parte, em um subconjunto de bits de uma transmissão de informação de controle de enlaces lateral (sci). o subconjunto de bits da transmissão de sci pode ser selecionado de tal modo que os bits tenham variabilidade suficiente para reduzir a probabilidade de múltiplos ues utilizarem a mesma sequência dmrs. o subconjunto de bits da transmissão sci pode ser todo ou parte de uma verificação de redundância cíclica (crc) para sci.
