Abstract
SINAL DE REFERÊNCIA DE POSICIONAMENTO (PRS) DE MÚLTIPLAS PORTAS PARA ESTIMAÇÃO DO ÂNGULO DE PARTIDA (AOD) DE DOWNLINK. São reveladas técnicas para posicionamento sem fio. Sob um aspecto, um equipamento de usuário (UE) recebe um conjunto de parâmetros de antena para uma pluralidade de portas de antena de um ponto de transmissão-recepção (TRP), obtém medições de posicionamento de uma pluralidade de recursos de sinal de referência de posicionamento (PRS) transmitidos na pluralidade de portas de antena, reconstrói um canal físico subjacente entre o TRP e o UE com base nas medições de posicionamento da pluralidade de recursos de PRS e determina uma medição do ângulo de chegada de downlink (DL-AoD) a partir do TRP para o UE com base no canal físico subjacente reconstruído.
