Title (EN) PEAK TO AVERAGE POWER RATIO REDUCTION IN ELAA
(FR) RÉDUCTION DU RAPPORT DE PUISSANCE DE CRÊTE SUR PUISSANCE MOYENNE EN ELAA
Abstract:
(EN) A method of uplink transmission to reduce peak-to-average power ratio (PAPR) in enhanced licensed assisted access (eLAA) is proposed. New design of Physical Uplink Control Channel (PUCCH) and Physical Uplink Shared Channel (PUSCH) is proposed. Across frequency domain of the channel bandwidth, multiple resource interlaces are allocated for different UEs for uplink PUCCH/PUSCH transmission to satisfy the occupied channel bandwidth requirement for unlicensed carrier access. In addition, uplink transmission with co-phasing terms are applied to reduce PAPR of the resulted waveform.
(FR) La présente invention concerne un procédé de transmission en liaison montante destiné à réduire le rapport de puissance de crête/puissance moyenne (PAPR) en accès assisté sous licence améliorée (eLAA). L'invention concerne également une nouvelle conception de canal de commande de liaison montante physique (PUCCH) et de canal partagé de liaison montante physique (PUSCH). Dans le domaine de fréquence de la largeur de bande de canal, des entrelacements de ressources multiples sont attribués à différents UE pour une transmission de PUCCH/PUSCH en liaison montante afin de satisfaire l'exigence de largeur de bande de canal occupé pour un accès à porteuses sans licence. En outre, une transmission en liaison montante à termes de cophasage est appliquée afin de réduire le PAPR de la forme d'onde obtenue.
