A method and apparatus for transmitting scheduling grant information by a TFCI in Node B controlled scheduling of uplink packet transmission. In one embodiment, a scheduling command resulting from Node B controlled scheduling is mapped onto a TFCI and transmitted on the downlink. In another embodiment, an ACK/NACK signal determining retransmission of uplink packet data is mapped onto a TFCI and transmitted on the downlink.

According to one embodiment of the invention, a method for controlling capacity of a wired or wireless network with varying bandwidth capacity is described. First, dynamic conditions associated with the data flow are measured. These dynamic conditions influence a bandwidth capacity for the data flow. Next, the capacity is estimated in order to adjust the data flow based on the estimated capacity per the measured dynamic conditions.

Capacity estimation and proportional sharing of varying capacity channels

A system and a method minimize power consumption, signalling overhead, and processing load in blind scheduling in a mobile communication system. A User Equipment (UE) detects a type of an uplink (UL) grant while it is periodically allocated the UL grant. If there is no data to transmit using the UL grant, the UE determines whether to transmit a padding Medium Access Control (MAC) Protocol Data Unit (PDU) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) using the UL grant according to the type of the UL grant.

Each transport format contains control parameters according to which data are mapped from at least one logical channel onto at least one transport channel by a data link layer protocol unit, with the control parameters in the transport formats containing information regarding that or those data link layer protocol buffer storages and/or that or those data link layer data streams from which the data to be transmitted need to be transmitted in a data transmission time interval.

There is disclosed a method and a device of controlling transmission errors in a network comprising at least one transmitter, at least one receiver and a Radio Resource Management (RRM) unit for allocating transmission resource dedicated to the transmitter and/or the receiver. A FeedBacK (FBK) function is introduced to manage transmission of feedback information which is transmitted by the receiver to the transmitter to indicate transmission errors. The FBK function comprises a transmitter FBK instance and a receiver FBK instance. At first, the transmitter FBK instance transmits Protocol Data Units (PDUs) to the receiver FBK instance. The FBK function monitors transmission errors on the receiver FBK instance side and/or on the transmitter FBK instance side to determine a transmission quality level out of a set of given transmission quality levels. The FBK function selects one feedback operational mode out of a predetermined list of feedback operational modes based on the determined transmission quality level, each one of feedback operational modes defining a feedback resource allocation scheme for the transmitter FBK instance and the receiver FBK instance. The receiver FBK instance transmits to the transmitter FBK instance feedback information via a resource allocated based on the selected feedback operational mode.

A scheduling method and device for scheduling data transmission, usually over a plurality of channels in a data network, wherein a utilization of an allocated maximum channel capacity in a received data stream of at least one of the plurality of channels is typically monitored, and future allocation of the maximum channel capacity is then normally controlled in response to the monitoring result. Thereby, data transmissions may be scheduled according to their often near instantaneous transmission capacity requirements, usually without requiring any explicit uplink signaling.
