Title
(EN) WLAN UPLINK SCHEDULER FOR LTE-WLAN AGGREGATION
(FR) PROGRAMMATEUR DE LIAISON MONTANTE WLAN POUR AGRÉGATION LTE-WLAN
Abstract
(EN)
Techniques for improving uplink throughput of UE uplink transmissions are disclosed. The UE may communicate with an eNB over an LTE wireless link using a first radio, and with a WLAN access point over a WLAN wireless link using a second radio. The UE may schedule a first portion of uplink data from an aggregating layer of the UE for transmission over the WLAN wireless link during a scheduling window, the scheduling based on an availability of access to the LTE wireless link. The UE may transmit the first portion of the uplink data over the WLAN wireless link during the scheduling window. The aggregation of the LTE wireless link with the WLAN wireless link may allow the UE to transmit uplink data from the aggregating layer of the UE over both the LTE wireless link or the WLAN wireless link.

L'invention concerne des techniques destinées à améliorer la capacité en liaison montante d'émissions d'UE en liaison montante. L'UE peut communiquer avec un eNB via une liaison sans fil LTE en utilisant une première radio, et avec un point d'accès WLAN via une liaison sans fil WLAN en utilisant une deuxième radio. L'UE peut programmer une première partie de données en liaison montante en provenance d'une couche d'agrégation de l'UE en vue de leur émission via la liaison sans fil WLAN pendant une fenêtre de programmation, la programmation étant basée sur la disponibilité d'un accès à la liaison sans fil LTE. L'UE peut émettre la première partie des données en liaison montante via la liaison sans fil WLAN pendant la fenêtre de programmation. L'agrégation de la liaison sans fil LTE avec la liaison sans fil WLAN peut permettre à l'UE d'émettre des données en liaison montante en provenance de la couche d'agrégation de l'UE aussi bien via la liaison sans fil LTE que via la liaison sans fil WLAN.
