摘要： The invention relates to a technique for uplink data transmissions, e.g. in mobile networks. An uplink data channel (UDACH) is provided for the uplink transmission of the packet data and an uplink control channel (UCOCH) is provided to enable the parallel uplink transmission of control information comprising at least one transmission parameter related to the transmission on the uplink data channel. A method embodiment for performing the technique in a transmitter (102) comprises the steps of evaluating a predefined condition for an assumption on an availability of the at least one transmission parameter at the receiver (104) without transmitting the at least one transmission parameter in parallel in the uplink control channel (UCOCH); and selectively omitting, depending on the evaluation, the parallel transmission (T2) of the at least one transmission parameter in the uplink control channel (UCOCH).

摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.
摘要翻译：在无线通信网络中，其中基站从移动台接收用于解压缩和解密的协议数据单元（PDU），用于有序的顺序传送作为服务数据单元（SDU）到相关联的核心网络，本文给出的教导提供了一种支持无缝将移动台从源基站切换到目标基站。作为示例，本文的教导适用于由3GPP公布的基于E-UTRA规范的网络。然而，该示例是非限制性的，因为本文的教导适用于在切换时采用顺序数据传递和重复数据检测的任何网络。广泛地说，源基站将无序SDU和相应的序列号信息转发给目标基站以支持无缝切换，目标基站使用该信息来根据需要重新分组以重新分组。

摘要： 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.
摘要翻译：根据本发明的方法和装置解决和/或防止由ACK / NACK错误引起的HARQ系统中丢失的协议同步。一个实施例检测基于NDI的重传协议的丢失的同步错误，并通过发送显式的RESET消息来恢复同步。响应于RESET消息，发射机中止当前PDU的传输，并发送新的PDU和相应的NDI。另一个实施例通过逐个分组地发送调度许可来防止协议同步错误。接收机基于接收到的PDU的错误评估向发射机发送后续的显式调度许可。发射机不会发送下一个PDU，除非它接收到后续的显式调度授权。

摘要： A method and nodes for providing adaptive segmentation in a higher protocol layer interacting with a lower protocol layer. An adaptable segmentation limit (200, 204), defining a threshold of a largest Protocol Data Unit (PDU) that is to be submitted to a lower protocol layer, is deployed at a higher protocol layer interacting with the lower protocol layer. For each Service Data Unit (SDU; 201, 203) arriving at the higher protocol layer, it is determined if the respective SDU can fit into the segmentation limit or not. Each SDU that do not fit into the segmentation limit is segmented into PDUs (205, 206) which are smaller than or equal to the segmentation limit, while no segmentation is performed on SDUs that fit into the segmentation limit.

摘要： A method of controlling the volume of user-plane traffic on the Iub or Iub/Iur interface between a Radio Network Controller and a Node B of a UMTS Radio Access Network during periods of overload. The method comprises, for individual uplink or downlink connections established over the Iub or Iub/Iur interface, monitoring at the Radio Network Controller the late arrival of frames at the Radio Network Controller or at the Node B transmitted over the Iub or Iub/Iur interface, and based on the results of said monitoring, causing a reduction in the Iub or Iub/Iur load for a connection when appropriate.

摘要： 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 (410, 900) determines (520) that handover of at least one radio bearer for a served user terminal (160) to a target base station node (430, 900) is imminent. The source base station node (410, 900) classifies (530) 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 (540) one or more of the data packets to the target base station node (430, 900) based on the data flow classification for each data packet. In some embodiments, the source base station node (410, 900) classifies (530) the data packets by inspecting (610) an Internet Protocol header for each packet to determine a corresponding service requirement. In some embodiments, the source base station node (410, 900) classifies (530) data packets by evaluating (650) a radio link control status to determine a transmission status for each data packet. In either case the source base station node (410, 900) selectively forwards (540) data packets corresponding to one or more of the classifications. 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.

摘要： UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n = the number of bits in C/T field.
