    Abstract: Control of a data packet buffer in a communication system is described. Control of a data packet queue in a transmission link is shown. In the queue there is stored a plurality of received data packets that are intended for transmission over a wireless interface. Selected packets are discarded from the queue without the selected packets having been transmitted. A packet is selected for discarding depending on at least the length of time the packet has been stored in the queue. The discarding of a selected packet is effectuated on condition that at least a predetermined time period has elapsed since a previous discarding of a packet has taken place. Such a solution is advantageous in that, for varying transmission bandwidth conditions in the transmission link, it is possible to achieve good link utilization and throughput, while at the same time enabling a low end-to-end delay for packets transmitted in the link.

    Abstract: A method and devices for performing a handover of a data unit based communication that involves a sequence of data units from a first connection (51) between a first sender (10) and a receiver (4) to a second connection (52) between a second sender (20) and said receiver (4), which comprises indicating to the receiver (4) a reference data unit among data units provided to both the first sender (10) and the second sender as a part of the handover, and where the receiver, based on the reference data unit, keeps a record for identifying such data units among those data units provided to both the first sender (10) and the second sender (20) that were sent over the first connection (51) and successfully received by the receiver (4), prior to the communication having been passed to the second communication (52).

    Abstract: A method of controlling a transmission of data units arranged in accordance with a predetermined communication protocol over a plurality of network entities, said network entities operating according to said predetermined communication protocol, from a sending network entity to a receiving network entity over one or more forwarding network entities, comprising providing in a data unit a first data field arranged to contain network entity identification information, said first data field being different from a forwarding data field designated by said communication protocol to contain information to be used by forwarding network entities for forwarding said data unit to the receiving network entity, said first data field being defined such that a given network entity that reads the first data field can at least make a decision on the basis thereof whether said given network entity is identified or not, and in said one or more forwarding network entities, performing a data unit processing operation after receiving said data unit, which comprises reading said first data field and making an identification decision on the basis thereof whether the forwarding network entity performing said data unit processing operation is identified or not.

    Abstract: La invención da a conocer un método (700) para un sistema celular (100), en el que se puede intercambiar tráfico entre el primer (110, 120) y el segundo (110, 120) transceptores. El tráfico se envía en unidades de datos, cada una de las cuales recibe un identificador, y dichas unidades de datos pueden dividirse en segmentos. Un transceptor receptor (110, 120) puede enviar información de estado en tramas de datos o unidades de datos (200, 300) sobre unidades de datos recibidas correctamente, parcialmente recibidas o no recibidas a un transceptor emisor, es decir, el transceptor desde el cual se enviaron los datos. . En el caso (705) de unidades de datos recibidas parcialmente o no recibidas, la información de estado incluye (710) información sobre si la unidad o unidades de datos no se recibieron o se recibieron parcialmente, y en el caso de una o más unidades de datos recibidas parcialmente , que (715) partes de esas unidades de datos que no se recibieron.

    Abstract: A network node for wireless access operating a cell in a cellular network for a licensed or unlicensed frequency band and arranged for serving wireless devices in an unlicensed frequency band is disclosed. The network node is arranged to transmit a discovery reference signal, DRS, comprising a first and a second synchronization signal for enabling the wireless devices to find and measure the cell, and wherein the DRS, when the network node operates a primary cell in the unlicensed frequency band, comprises system information, and additional or adapted synchronization signal for enabling the wireless devices to identify the presence of the system information and acquire further cell information. A wireless device for operating with such a network node is also disclosed. The wireless device is arranged to receive a transmission from the network node, determine synchronization signals in the transmission, and from the synchronization signals determine whether it is a discovery reference signal, DRS, comprising system information by identifying an additional or adapted synchronization signal in the transmission, and, upon determined presence of the system information, read the system information. Methods and computer programs for the network node and the wireless device are also disclosed.
