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 radio base station (28) suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver (34) and a status report requester (60). The transceiver (34) is configured to facilitate wireless transmission between the radio base station (28) and a wireless terminal (30) over an air interface, including transmission of a radio link bearer for the connection over a downlink from the radio base station to the wireless terminal. The status report requester (60) is configured to determine, according to one or more pre-defined criteria, whether to request from the wireless terminal a status report for a radio bearer prior to the radio base station transferring user data for the connection to another radio base station in conjunction with a handover.

摘要： According to the invention data in a number of logical downlink channels (PCCH, CCCH, BCCH, CTCH, MCCH, MSCH and MTCH) intended for one or more mobile terminals are received in a first mapping unit (10), where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel (HS-DCH) and processes said data.

摘要： The invention relates to a method for performing a data transmission between a sending entity and a receiving entity. The sending entity provides the data in form of data packets being ordered in a sequence. In order to make the data transmission more efficient when packet reordering occur on the communication link between the protocol entities, the receiver entity at a reception of a data packet which is out of the sequence order, delays a triggering of a reordering procedure for providing the sequence order at the receiver by means of a delay parameter whereby during the duration of the delay the establishment of the sequence order of the incoming data packets is controlled by means of a controlling parameter.

摘要： A radio access network node (24) comprises protocol data unit (PDU) formation logic (36); a PDU buffer (38): a concatenation timer (40): and a buffer readout mechanism (39). The protocol data unit (PDU) formation logic (36) serves. e.g.. for segmenting incoming service data units (SDUs) to form protocol data unit (PDUs). The PDU buffer (38) stores one or more PDUs. The buffer readout mechanism (39) controls readout of contents of the PDU buffer (38). For example, when contents of a PDU in the PDU buffer (38) has not reach a predetermined fill level, the buffer readout mechanism (39) uses the concatenation timer for determining a delay for readout of the PDU from the PDU buffer (38). The delay provides opportunity for at least a portion of a yet-arrived SDU to be included in the PDU prior to readout of the PDU from the PDU buffer (38), and thereby reduce padding in an outgoing PDU.

摘要： The present invention relates to method and arrangements for using an identifier of a predefined type, e.g. an RNTI identifying one configuration on an out-band control channel for activating the configuration identifiable by that identifier. The identifier is sent from the network to the UE (904), when a configuration corresponding to that identifier is to be activated. This implies that both the UE and the radio base station comprise a mapping (901) between each configuration (902,903) and the corresponding identity of each configuration.
摘要翻译：本发明涉及使用预定义类型的标识符的方法和装置，例如， RNTI识别带外控制信道上的一个配置，用于激活由该标识符可识别的配置。当要激活与该标识符相对应的配置时，该标识符从网络发送到UE（904）。这意味着UE和无线电基站都包括每个配置（902,903）和每个配置的相应身份之间的映射（901）。
