Abstract

métodos realizados por um dispositivo sem fio e por uma estação base, dispositivo sem fio, e, estação base. são providos sistemas e métodos para canais compartilhados de enlace ascendente físico (pusch) de múltiplos pontos de transmissão e recepção (trp) não baseados em livro de códigos. em algumas modalidades, um método realizado por um dispositivo sem fio inclui: receber uma configuração de um primeiro ou segundo índice de porta de sinais de referência de rastreamento de fase (pt-rs) por recurso de sinal de referência de sondagem (srs) em dois conjuntos de recursos de srs para não livro de código baseado em pusch; receber indicação de: um primeiro conjunto de indicadores de recursos de srs (sris) de um primeiro conjunto de recursos de srs; e/ou um segundo conjunto de sris de um segundo conjunto de recursos de srs; determinar pelo menos um dentre: um primeiro número de portas de pt-rs a serem transmitidas de acordo com os recursos de srs indicados no primeiro conjunto de sris; e um segundo número de portas de pt-rs a serem transmitidas de acordo com os recursos de srs indicados no segundo conjunto de sris; e transmitir o número determinado de portas de pt-rs juntamente com uma pluralidade de repetições de pusch.
