Title
(EN) REPORTING OF PACKET HEADROOM PER SUB-BAND
(FR) RAPPORT DE MARGE DE PAQUET PAR SOUS-BANDE
Abstract
(EN) Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE determines a transmission power configuration for an uplink transmission on a bandwidth multiple sub-bands associated with different transmission power levels. The UE transmits, to a network component, a PHR that indicates a sub-band headroom value for each sub-band. The network component receives the PHR and performs a power control function associated with the UE based at least in part upon the PHR (e.g., per sub-band).
(FR) Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un UE détermine une configuration de puissance de transmission pour une transmission de liaison montante sur une bande passante de multiples sous-bandes associées à différents niveaux de puissance de transmission. L'UE transmet, à un composant de réseau, un PHR qui indique une valeur de marge de sous-bande pour chaque sous-bande. Le composant de réseau reçoit le PHR et effectue une fonction de commande de puissance associée à l'UE sur la base, au moins en partie, du PHR (par exemple, par sous-bande).
