Abstract

1/1 resumo “adaptação de link centrada em rede para transmissão de downlink de multipontos coordenados” trata-se de um controlador de célula de multipontos coordenados (comp) que realiza adaptação de link centrada em rede para equipamento de usuário (ue) na célula de comp. o controlador de célula de comp recebe pelo menos estimativas de infrequentes de canal de um ue na célula de comp, da qual o mesmo estima canal de downlink e ruído térmico no ue. o controlador de célula de comp está ciente do sinal desejado a ser recebido no ue, e a interferência de célula de intracomp ao ue causada por transmissões a outros ues na célula de comp. a célula de comp recebe do ue relatórios de interferência de célula de intercomp causada por transmissões por outras células de comp. com base na qualidade de canal de downlink, no sinal desejado, na interferência de célula de intracomp, na interferência de célula de intercomp e no ruído térmico, o controlador de célula de comp realiza adaptação de link selecionando-se esquemas de modulação e codificação, e outros parâmetros de transmissão, por uma duração de transmissão de chegada (tal como um tti).1/1 summary “network-centric link adaptation for coordinated multipoint downlink transmission” is a coordinated multipoint (comp) cell controller that performs network-centric link adaptation for user equipment (eu) in the cell of comp. the comp cell controller receives at least infrequent channel estimates of a eu in the comp cell, of which it estimates downlink channel and thermal noise in the eu. the comp cell controller is aware of the desired signal to be received in the eu, and intracomp cell interference to the eu caused by transmissions to other ues in the comp cell. The comp cell receives reports of intercomp cell interference caused by transmissions by other comp cells. based on downlink channel quality, desired signal, intracomp cell interference, intercomp cell interference, and thermal noise, the comp cell controller performs link adaptation by selecting modulation and coding schemes, and other transmission parameters, for an arrival transmission duration (such as a tti).
