摘要： A method of controlling the sending of data packets from a Base Station (BS) of a Radio Access Network (RAN) to a UE, where the BS is one of a set of BSs transmitting identical data to the UE and each said data packet has a sequence number. The method comprises implementing at the BS an Automatic Repetition reQuest (ARQ) mechanism for resending data packets erroneously received by the UE and, upon receipt of an ARQ status message from the UE, advancing a transmission window of the BS so that its lower region covers the packet having the highest sequence number for which an ARQ acknowledgement has nor yet been received. Where a single BS is transmitting in the downlink direction, and a soft handover set exists for an uplink reverse channel, downlink sending buffers of the BSs of the soft handover set may be synchronized by the exchange of ARQ messages between BSs.
摘要翻译：一种控制从无线电接入网（RAN）的基站（RAN）向UE发送数据分组的方法，其中BS是向UE发送相同数据的一组BS之一，并且每个所述数据分组具有一个序列号。该方法包括在BS处实现用于重新发送由UE错误接收的数据分组的自动重复请求（ARQ）机制，并且在从UE接收到ARQ状态消息时，推进BS的传输窗口，使得其下部区域覆盖具有最高序列号的分组，其中ARQ确认尚未被接收。在单个BS正在下行链路方向上发送，并且对于上行链路反向信道存在软切换集合的情况下，软切换集合的BS的下行链路发送缓冲器可以通过BS之间的ARQ消息的交换来同步。

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.

摘要： A radio base station suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver and a status report requester. The transceiver is configured to facilitate wireless transmission between the radio base station and a wireless terminal 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 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： A method of handling the transmission of Radio Link Control (RLC) Protocol Data Units (PDUs) from a Radio Access Network (RAN) of a mobile telecommunications system to User Equipment (UE). At a Gateway of the RAN, RLC Service Data Units (SDUs) are segmented into RLC PDUs for transmission to one or more Base Stations (BSs) of a set of BSs belonging to a handover link set. RLC PDUs received from one or more of those BSs are combined into RLC SDUs for transmission to a core network of the system. Each of the BSs buffers the RLC PDUs received from the Gateway and/or the UE. An Automatic Repetition Request (ARQ) mechanism is implemented at each of the BSs to facilitate reliable transmission of RLC PDUs between the UE and the Gateway.

摘要： In a UMTS Terrestrial Radio Access Network (UTRAN), a method of switching from a current common channel to a dedicated channel for a UE. The method comprises estimating the round trip delay for data packets travelling between the UE and a peer node with which the UE is communicating. The product of the estimated round trip delay and the bandwidth of the common channel or the dedicated channel is determined and a threshold defined on the basis of that product. A switch from the common channel to a dedicated channel is initiated when the fill level of the RLC buffer(s) in the UTRAN for the UE reaches or exceeds said threshold.

摘要： A cell change procedure for user equipment (UE) situated in a serving cell. An active set of cells comprises a list of cells to which the UE can move from the serving cell. The UE sends a request to a network controller to add at least one further cell to the active set. The UE then receives the requested active set update from the network controller with the further cell and a list of cells to which a modified cell change procedure shall be used for handover. A neighbor cell which is stronger than a current serving cell is detected. This detected stronger neighbor cell is matching with the received list of modified cell change procedure cells, and the modified cell change procedure for the handover to the stronger neighbor cell is applied if the stronger neighbor cell is found matching a cell on the list.

摘要： In a method for the transmission of data packets (D) from a transmitter (TR) to a receiver (RE) identification of transmitted data packets are stored. Defective data packets (D) are detected by the receiver (RE), status messages (S) which request defective data packets for retransmission are sent from the receiver (RE) to the transmitter (TR) and retransmissions of requested data packets are performed according to the status messages (S). The transmitter (TR) evaluates a first status message (S11) with an identification of at least one first requested data packet and retransmits the first data packet. The transmitter (TR) then initializes a timing unit according to the retransmission of the first data packet, wherein the timing unit or a threshold for the timing unit is attributable to the first data packet. When the transmitter evaluates a further status message (S12) and detects at least one further data packet that is requested for a retransmission, it selects the further data packet if the timing unit has reached the threshold or if the identification of the further data packet is different from the identification of the first data packets. Only the selected data packets are retransmitted. A transmitter and software programs embodying the invention are also described.
