摘要： 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).

摘要： It is disclosed a method for scheduling data packets and control information in a telecommunication network, wherein data packets and control information are scheduled for transmission in a group of OFDM symbols available in a transmission time interval (TTI). A set of the data packets to be scheduled is first selected (401) by a scheduler, which then searches (402) control solutions for scheduling control information associated to the set of data packets in a predetermined number of OFDM symbols of the group of OFDM symbols. The scheduler searches data solutions for scheduling the selected data packets in the other OFDM symbols available. Scheduler repeats the searches of data and control solutions considering a different set of data packets and a different number of OFDM symbols for scheduling control information. Finally, scheduler schedules (411) data packets and control information according to a scheduling solution wherein control information are scheduled according to a control solution and data packets are scheduled according to a data solution associated to the control solution.

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

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 (I MCS ) and transmission power in a set of physical resource blocks in the frequency domain. The method identifies the relationship between the transmission power and the block error rate (BLER) for a set of transmission formats (I MCS ) / and evaluates alternative transmission formats (I MCS ) and different numbers of physical resource blocks for at least one of the transport blocks. Specifically, the method determines a set of alternative transmission formats (I MCS ) with different numbers of physical resource blocks, and determines a value being indicative for the total power difference required to transmit the transport block with the alternative transmission format (I MCS ) and different number of physical resource blocks, while maintaining a target block error rate (BLER T ). The transport block is then transmitted with the alternative transmission format (I MCS ) and different number of physical resource blocks if the value indicates that the total transmission power is lower.

摘要： Downlink and uplink communication resources to ensure network coverage and satisfy assigned cell traffic requirements in a cellular communication network are allocated by setting (102) a given balance of downlink and uplink communication resources while leaving a part of said downlink and uplink communication resources remaining to be allocated. Downlink cell radius and uplink cell radius values are then determined (103) which ensure network coverage with the resources as previously allocated. An effective cell radius is then selected (1041) as the smaller of the downlink cell radius and uplink cell radius and then a first check (1042) is made as to whether the effective cell radius selected satisfies the assigned cell traffic requirements. If that first check (1042) yields a negative result, the effective cell radius is updated (10425) by reducing the value thereof and repeating the previous step by using the reduced updated value. Once the first check (1042) yields a positive outcome, a further check (1044) may be made as whether the resources remaining to be allocated for downlink and uplink have a difference in excess of a given amount. If the further check (1044) yields a positive outcome, the whole procedure is repeated by setting (1046) an updated balance of downlink and uplink communication resources reducing tϊiat difference. Once the further check (1044) yields a negative outcome, the communication resources are finally allocated on the basis of the current balance.
