Abstract

devido à dimensão limitada de uma nb que pode ser utilizada por múltiplos usuários, assim como pode ser utilizada em grandes áreas de cobertura, a estimativa de deslocamento de temporização pode estar fora de um ncp. a incerteza na estimativa de temporização pode ser aperfeiçoada através do uso de uma ou mais distância de salto de tom para prach. um aparelho pode, então, transmitir um primeiro e um segundo tom do prach em uma primeira distância de salto a partir de um primeiro tom. o aparelho pode, então, transmitir um terceiro tom do prach e um quarto tom do prach em uma segunda distância de salto a partir do terceiro tom. a segunda distância de salto pode ser maior do que a primeira distância de salto. o aparelho pode, ainda, transmitir um tom adicional do prach utilizando uma distância de salto aleatória. um aparelho de recebimento pode receber o prach transmitido e determinar uma estimativa de fase baseado nos conjuntos de tons tendo diferentes distâncias de salto.
