(EN)In a communication network (e.g. HSUPA or LTE), a node such as a NodeB receives from a user equipment (UE) information on the length of a queue of information units to be transmitted to the node from the user equipment. The information, for possible use by the node (NodeB) in scheduling transmission of these information units from the user equipment (UE), is in the form of quantized queue length information indicative of a lower bound and an upper bound for the queue length. Transmission of information units from the user equipment (UE) to the node (NodeB) is detected at the node (NodeB), and an improved estimate of the queue length is produced by correcting the lower bound and the upper bound via subtraction of the number of the detected information units transmitted from the user equipment (UE) to the node (NodeB).

Abstract

(EN)In a communication network (e.g. HSUPA or LTE), a node such as a NodeB receives from a user equipment (UE) information on the length of a queue of information units to be transmitted to the node from the user equipment. The information, for possible use by the node (NodeB) in scheduling transmission of these information units from the user equipment (UE), is in the form of quantized queue length information indicative of a lower bound and an upper bound for the queue length. Transmission of information units from the user equipment (UE) to the node (NodeB) is detected at the node (NodeB), and an improved estimate of the queue length is produced by correcting the lower bound and the upper bound via subtraction of the number of the detected information units transmitted from the user equipment (UE) to the node (NodeB).
