Abstract: The present invention relates to a method and system for providing a downlink connection in a cellular network. A feedback information indicating a selected cell is transmitted to a central network element (20) controlling at least two network elements (N1–N3) serving cells (C1–C3) of the cellular network. The at least two network elements are controlled by the central network element based on the feedback information so as to establish the downlink connection. Thus, the downlink transmissions of the non-central network elements (N1–N3) are controlled by the network so as to decrease performance loss due to reception errors of the feedback information. The feedback information may be a temporary ID obtained in a site selection diversity transmission control scheme.

Abstract: A method is described for transmitting data, particularly but not exclusively packet data, from a transmitting station to a receiving station via a wireless channel. The data is transmitted in transmission intervals or TTI slots. The method comprises estimating a utilisation factor representing usage of the transmission intervals, and scheduling the data for transmission to increase the utilisation factor. The effect is to reduce stochastic pattern interference for other users in a wireless communications network. A network node for implementing the above method is also disclosed.

Abstract: A system has user equipment (1; 2) each having buffers (3, 4, 5, 6; 7, 8, 9, 10) for storing packets classified according to priority and ready for transmission over a radio interface to a network element (12). In such a system, user equipment sends capacity request signals (11; 13) indicative of the various priorities of the buffered packets on the radio interface to the network element. Rather than seeking a capacity allocation decision from a higher level in the core network, the network element itself makes the capacity allocation decision and provides a capacity allocation signal (14) to the user equipment. Packets that have thus been allocated capacity by the network element are then sent from the user equipment to the network element. Having the network element make the capacity allocation decisions itself is a more efficient system since the network element is in direct communication with the user equipment over the radio interface and the decision is made in an unmediated way.

Abstract: The invention is related to a data transmission method in a telecommunication system. The method comprises determining the number of bit rate classes, setting bit rates for the bit rate classes, setting a maximum transmission power target, arranging resource requests into a queue, allocating resources according to the requests in the queue until the maximum power target is achieved.

Abstract: The present invention relates to a method and a device for controlling power in a network transmitted from a first station to a second station. The second station determines a power target value for a signal received from the first station and sends power control commands to the first station depending on a deviation between said power target value and a received power level. The second station detects faulty data blocks received from the first station and requests retransmission of faulty data blocks from the first station. The adjustment of the power target value to a temporary power target value during the retransmission is performed such that the temporary power target value is calculated depending on the quality of a faulty data block.

Abstract: The present invention relates to a method and network device for transmitting data through a wireless transmission link using at least two reception beams. A reception beam through which the data has been received is determined and a modulation code for modulating the data is allocated according to the determined reception beam. Thereby, a specific code, e.g. scrambling code, can be assigned to a user equipment (50) depending on the beam it is connected to. Using this strategy for code assignment, own-cell signals received under one reception beam can be orthogonal assuming a synchronized transmission scheme. Signals received under another reception beam using another code will not be orthogonal, but this interference contribution is suppressed by the spatial filtering gain offered by the beamforming antenna system.

An information indicating a re-transmission status of a data packet is provided to the base station device, and a scheduling priority is allocated to the data packet based on the retransmission status information. Thereby, retransmission packets can be scheduled earlier and round trip times can be reduced, so as to decrease the risk of timeouts and stalling and to loosen buffer requirements.
