Abstract

Methods, devices and systems are provided for incorporating a consideration of the quality of service (QoS) of different end-to-end paths in a network, or portions thereof, into the scheduling of uplink data and the selection of data by a user device for transmission to one or more target reception points in a network. The target reception points may be determined from a number of possible reception points by a scheduling entity or by a network access node, gateway or other entity in the network and provided to a user device along with one or more indications of QoS for an uplink scheduling grant.
