Abstract

PROJETO DE PACOTE DE CAMADA FÍSICA (PHY) PARA LIMITES DE DENSIDADE ESPECTRAL DE POTÊNCIA (PSD). Esta revelação proporciona fornece sistemas, métodos e aparelhos, incluindo programas de computador codificados em mídia de armazenamento de computador, para projeto de pacote de camada física (PHY) para limites de densidade espectral de potência (PSD). Em algumas implementações, um dispositivo de comunicação não cabeada gera várias duplicatas de unidade de dados de protocolo (PPDU) de protocolo de convergência PHY (PLCP) configuradas para transmissão em uma largura de banda selecionada e transmite cada duplicata da PPDU das várias duplicatas da PPDU em uma sub-banda de frequências correspondente várias sub-bandas de frequências diferentes. Em algumas outras implementações, o dispositivo de comunicação não cabeado gera uma PPDU para transmissão através de um conjunto de unidades de recursos duplicadas (RUs) alocadas ao dispositivo de comunicação não cabeado e transmite a PPDU pelo conjunto alocado das RUs duplicadas.
