    Abstract: The present invention relates to a method and arrangement for communicating a Protocol Data Unit (PDU) between a transmitter unit and a receiver unit in a wireless communication network. Said PDU comprising protocol headers associated with at least a first and a second protocol layers involved in the communication and a payload to be communicated. The method comprises the step of interacting between the at least first and second protocol layers, such that the sum of the bits of the protocol headers is n-bit aligned such as octet aligned independently of non-alignment of at least one of the protocol headers comprised in the PDU.

    Abstract: The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.

    Abstract: Methods and devices are disclosed for forwarding data packets during handover in a packet-switched wireless communications system, such as a 3GPP Long-Term Evolution/System Architecture Evolution system. In an exemplary method, a source base station node determines that handover of at least one radio bearer for a served user terminal to a target base station node is imminent. The source base station node classifies a plurality of data packets into two or more data flow classifications according to a transmission status for each data packet, a service requirement for each data packet, or both and selectively forwards one or more of the data packets to the target base station node based on the data flow classification for each data packet. For example, data packets associated with a reliable delivery service requirement may be forwarded while data packets associated with a maximum delay service requirement are not.

    Abstract: A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer (48) of the client device.

    Abstract: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.
