    摘要: A method executed in a wireless communication network including at least one base station associated to a corresponding area transmitting/receiving data to/from corresponding user terminals located within the area. The method generates a user-rate matrix for each base station. Each element of the user-rate matrix provides a corresponding score, in terms of achievable rate, to a user terminal or group of user terminals within the corresponding area when a transmission is made to/from the user terminal or group of user terminals, respectively, from/to the base station by employing a selected transmission mode. The method further processes the elements of the user-rate matrix to create a scheduling list sorting the elements by a decreasing score, and associating to each user terminal a corresponding selected transmission mode based on the scheduling list for the transmission/reception of data to/from the base station.

    摘要: A method scheduling resources allocation within a wireless communications network including at least one network cell including a central unit providing coverage over the network cell and managing at least one transmission frame for putting the central unit into communication with at least one user equipment. The method includes: retrieving input parameters including, for each user equipment, a channel quality parameter indicating a measured/estimated channel quality based on actual network cell conditions; applying a de-contextualization function to each channel quality parameter for obtaining a corresponding atomic channel quality parameter indicating channel quality de-contextualized from the actual network cell conditions; performing a scheduling algorithm providing a binary allocation matrix indicating each scheduled physical resource block, transmission frame and user equipment; and applying a contextualization function to the allocation matrix obtaining transport block size data usable by the scheduled transmission frame for transport blocks transmissions from or towards each scheduled user equipment.

    摘要: In a communication network, a node receives from user equipment 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 in scheduling transmission of these information units from the user equipment, 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 to the node is detected at the node, 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 to the node.

    摘要: Data streams are transmitted from a node towards a receiver in a communication network in the form of data packets for playout via a reproduction buffer at the receiver. The data packets are arranged in a scheduling queue and dropped from the scheduling queue if their sojourn time in the queue exceeds a given drop deadline. The reproduction buffer is emulated at the node in order to determine respective playout values for the data packets which are indicative of expected playout instants for the data packets by the reproduction buffer at the receiver. The drop deadlines are assigned to the data packets as a function of the respective playout values determined via the reproduction buffer as emulated at the node.
