Title
(EN) TECHNIQUES FOR SUPPORTING MULTIPLE WAVEFORMS IN WIRELESS COMMUNICATIONS
(FR) TECHNIQUES DE PRISE EN CHARGE DE FORMES D'ONDES MULTIPLES DANS DES COMMUNICATIONS SANS FIL
Abstract
(EN)
Aspects described herein relate to determining multiple waveforms for transmitting wireless communications. A control waveform can be determined for transmitting a control information transmission related to a data transmission as one of multiple waveforms. A data waveform can be determined for transmitting the data transmission as one of the multiple waveforms. The control information transmission can be transmitted based on the control waveform, and the data transmission can be transmitted based on the data waveform.

La présente invention concerne, selon certains aspects, la détermination de multiples formes d'ondes pour transmettre des communications sans fil. Une forme d'onde de commande peut être déterminée pour transmettre une transmission d'informations de commande relative à une transmission de données sous la forme d'une forme d'onde parmi de multiples formes d'onde. Une forme d'onde de données peut être déterminée pour transmettre la transmission de données sous la forme d'une forme d'onde parmi les multiples formes d'onde. La transmission d'informations de commande peut être transmise en fonction de la forme d'onde de commande et la transmission de données peut être transmise en fonction de la forme d'onde de données.
