Abstract
(EN) Certain aspects of the present disclosure provide a technique executed by a user equipment (UE) for obtaining a burst of transmission control protocol (TCP) packets conveying packet data convergence protocol (PDCP) protocol data units (PDUs) by an application protocol TCP layer of a communication protocol stack of the UE. The UE may then determine a first number of a first plurality of acknowledge (ACK) tokens to transmit in a first transmission time interval (TTI) based on an amount of data used to ACK the burst of TCP packets. The UE may then transmit the first plurality of ACK tokens in the first TTI and a single ACK token in a second TTI subsequent to the first TTI.
(FR) Certains aspects de la présente invention concernent une technique exécutée par un équipement utilisateur (UE) permettant d'obtenir une rafale de paquets de protocole de commande de transmission (TCP) transportant des unités de données de protocole (PDU) de protocole de convergence de données par paquets (PDCP) au moyen d'une couche TCP de protocole d'application d'une pile de protocoles de communication de l'UE. L'UE peut ensuite déterminer un premier nombre d'une première pluralité de jetons d'accusé de réception (ACK) à transmettre dans un premier intervalle de temps de transmission (TTI) sur la base d'une quantité de données utilisées pour accuser réception de la rafale de paquets TCP. L'UE peut ensuite transmettre la première pluralité de jetons ACK dans le premier TTI et un seul jeton ACK dans un second TTI suivant le premier TTI.
