Abstract

ESTIMAÇÃO DE CANAL PARA CONTROLE DE SIDELINK DE DOIS ESTÁGIOS QUE UTILIZA DMRS DE CANAL DE DADOS DE SIDELINK. Determinados aspectos da presente revelação fornecem técnicas para estimação de canal para controle de sidelink de dois estágios que utiliza sinais de referência de demodulação (DMRS) de canal de dados de sidelink. Um equipamento de usuário (UF) pode transmitir o DMRS para o canal de dados de sidelink. O UE pode transmitir o segundo estágio do controle de sidelink utilizando portas de antena ou um pré-codificador utilizado para o canal de dados de sidelink. O dispositivo de recepção pode receber o DMRS, estimar o canal e demodular o segundo estágio de controle de sidelink com base no canal estimado. O dispositivo de recepção pode determinar de modo flexível o DMRS a ser utilizado para a estimação e demodulação.
