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 of scheduling data transmission of transport blocks in an Orthogonal Frequency-Division Multiple Access communication system, wherein each of the transport blocks is transmitted with a respective transmission format and transmission power in a set of physical resource blocks in the frequency domain. The method identifies the relationship between transmission power and the block error rate for a set of transmission formats, and evaluates alternative transmission formats and different numbers of physical resource blocks for at least one of the transport blocks. The method determines a set of alternative transmission formats with different numbers of physical resource blocks, and determines a value indicating the total power difference required to transmit the transport block, while maintaining a target block error rate. The transport block is then transmitted with the alternative transmission format and different number of physical resource blocks if the value indicates that the total transmission power is less.

摘要： A method scheduling data packets and control information in a telecommunication network for transmission in a group of OFDM symbols available in a transmission time interval. A set of the data packets to be scheduled is first selected by a scheduler, which then searches control solutions for scheduling control information associated to the set of data packets in a predetermined number of OFDM symbols of the OFDM symbol group. The scheduler searches data solutions for scheduling the selected data packets in other OFDM symbols available. The scheduler repeats searches of data and control solutions considering different sets of data packets and different numbers of OFDM symbols for scheduling control information. Finally, the scheduler schedules data packets and control information according to a scheduling solution, wherein control information is scheduled according to a control solution and data packets are scheduled according to a data solution associated to the control solution.

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.
