Abstract: There is provided packet handling in a client node (17a) between a hub node (16a) and a radio base station (13a) in a wireless network (10a, 10b, 10c). A method performed by a client node comprises wirelessly receiving (S102) packets from a hub node (16a). The packets are received in an order and being associated with an in-sequence order. A method performed by a client node comprises detecting (S104) that at least one packet of the packets is received out of said in-sequence order, and in response thereto providing an indicator indicating the in-sequence order. A method performed by a client node comprises providing (S106) the packets and the indicator to a radio base station (13a).

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for sending fast negative acknowledgements (NACKs) after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a NACK timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

Abstract: Indication of delivery-path information may benefit various communication systems. For example, wireless communication systems may benefit from per-protocol data unit delivery-path indication to data recipient or from setting a timer expiry value dependent on such received information. A method can comprise sending, by a data-sending protocol entity, a control protocol data unit. The control protocol data unit can identify protocol data units destined to a data-receiving protocol entity. The method can also comprise providing in the control protocol data unit, for each of the identified protocol data units, a direct or indirect indication of at least one delay figure of a delivery path chosen for an initial transmission of the identified protocol data unit.

Abstract: The present invention relates to a method of managing a packet administration map for data packets to be received via a network, particularly for packet groups organized in sequences of consecutive packets. In the field of networking and reliable data transport, as for example in case of TCP, bursty packet drops occur during a data transmission. Especially in high speed networks like in 10 Gb Ethernet, the handling of lost and retransmitted packets can introduce a disproportionate decrease of the net data rate. A reliable transport protocol usually retransmits a data packet that a receiver was not able to receive and thus was not acknowledged. In order to manage data packets that are retransmitted, a receiver in the network monitors sequence numbers and stores missing sequence numbers within an internal data structure, called packet administration map. According to the invention a reversed keying is used which means that the upper limit of the range of contiguous missing data packets is used as the key entry in the administration map. As the retransmitted packets usually are retransmitted in an increasing order of sequence numbers, with the help of the invention it becomes very seldomly necessary to split a packet administration entry or to create a new packet administration entry.

Abstract translation: 本发明涉及一种管理要经由网络接收的数据分组的分组管理映射的方法，特别是针对以连续分组的顺序组织的分组组。 在网络和可靠数据传输领域，例如在TCP的情况下，在数据传输期间发生突发分组丢失。 特别是在像10 Gb以太网这样的高速网络中，丢失和重发数据包的处理可能会导致净数据速率的不成比例的下降。 可靠的传输协议通常重传接收机不能接收的数据分组，因此未被承认。 为了管理重传的数据包，网络中的接收器监视序列号，并在内部数据结构中存储丢失的序列号，称为数据包管理映射。 根据本发明，使用反向键控，这意味着连续丢失数据分组的范围的上限被用作管理图中的键入口。 由于重传的分组通常按照序列号的增加顺序被重传，借助于本发明，分割分组管理条目或者创建新的分组管理条目变得非常必要。

Abstract: Techniques for sending packets and maintaining synchronization during handover is described. A user equipment (UE) may be handed over from a source base station to a target base station. The source base station may forward packets for the UE to the target base station, which may receive the packets out of order. In one design, the target base station may determine whether each packet can be sent in order to the UE, send the packet if it can be sent in order, and discard the packet otherwise. In another design, the target base station may re-order packets received within a re-ordering window and may send the re-ordered packets to the UE. In yet another design, the target base station may process each packet received out of order as if the packet is in order, e.g., by incrementing a hyper-frame number (HFN) or re-assigning the packet with a later sequence number.

Abstract: Systems and methodologies are described that facilitate processing service data units (SDU) in-order during communication handover in wireless networks. In particular, for mobile devices using re-transmission schemes, SDUs can be processed in-order by indicating to a target base station an index of a last SDU received in-order before handing off communication to the target base station. Additionally, SDUs received subsequent to one or more non-acknowledged SDUs can be forwarded to the target base station. Utilizing this information, the target base station can determine one or more SDUs the mobile device is preparing to re-transmit and can wait for this SDU before processing subsequently received SDUs. Also, a timer can be utilized to end a waiting period for the SDU.
