Abstract

a presente invenção se refere a técnicas que permitem a seleção da forma de onda para transmissões sem fio em uplink (ul) e/ou downlink (dl) com base em um ou mais fatores associados à transmissão sem fio, um transmissor que vai transmitir a transmissão sem fio ou suas combinações. as transmissões em ul e dl podem usar uma série de diferentes formas de onda, como formas de onda de portadora única que usam uma única portadora para transmissão de informações de um canal sem fio, e formas de onda de multiportadora que usam várias portadoras em frequências diferentes para transmitir alguns dos bits em cada canal. as formas de onda de transmissão multiportadora ou formas de onda de portadora única podem ser selecionadas para transmissões sem fio com base em uma largura de banda alocada para as transmissões, uma funcionalidade de um transmissor que vai transmitir as transmissões ou suas combinações.
