摘要： The present invention aims to solve the problem that the preamble ramping process on a random access channel (RACH) of a 3rd generation telecommunication network can take a considerable time and, as a consequence, cause significant delays in RRC signalling and user data transmission on RACH. The present invention suggests to base the calculation of the initial preamble power value on the last performed RACH transmission instead of calculating the initial preamble power from the information that is broadcasted in the system information. This results in fewer preamble rampings until the preamble is detected in the Node-B.
摘要翻译：本发明旨在解决第三代电信网络的随机接入信道（RACH）上的前导码斜坡处理可能花费相当长的时间并因此导致在RACH上的RRC信令和用户数据传输中的显着延迟的问题。本发明建议基于最后执行的RACH传输的初始前导码功率值的计算，而不是根据在系统信息中广播的信息来计算初始前导码功率。这导致在节点B中检测到前同步码之前较少的前导斜坡。

摘要： A data communication having at least one data flow is established over a wireless interface between a radio network and a user equipment node (UE). A medium access control (MAC) layer located in a radio network node receives data units from a higher radio link control (RLC) layer located in another radio network node. Some or all of a header of a RLC data units associated with the one data flow is analyzed at the MAC layer. Based on that analysis, the MAC layer determines a priority of the data unit relative to other data units associated with the one data flow. The MAC layer schedules transmission of higher priority data units associated with the one data flow before lower priority data units associated with the one data flow. The priority determination does not require extra priority flags or signaling.

摘要： A telecommunications device comprises a transceiver (33); a radio link control entity (50); and, a radio link control (RLC) buffer memory (150). The transceiver (33) which enables the device to communicate over an air interface (32). The radio link control entity (50) forms uplink RLC protocol data units (PDUs) for transmission over the air interface (32) and receives downlink RLC protocol data units (PDUs) over the air interface (32). The radio link control (RLC) buffer memory (150) is configured to include a transmitter buffer for storing the uplink RLC protocol data units (PDUs) and a receiver buffer for storing the downlink RLC protocol data units (PDUs). The radio link control entity includes RLC reconfiguration logic means (200) which reconfigures at least one of a size of a transmitter buffer window and a size of a receiver buffer window. In performing the reconfiguration, the RLC reconfiguration logic means implements a strategy for handling at least one of (1) downlink RLC protocol data units (PDUs) which are outside a new receiver buffer window; and (2) uplink RLC protocol data units (PDUs) which are either outside a new transmitter window or whose receipt by the radio access network has not been positively acknowledged.

摘要： A radio communications link is established between radio stations, and a semi-persistent radio resource is allocated to support data transmission over the communications link. The semi-persistent radio resource is associated with a corresponding automatic repeat request (ARQ) process identifier. Non-limiting examples of a semi-persistent radio resource include a regularly scheduled transmission time interval, frame, subframe, or time slot during which to transmit a data unit over the radio interface. Retransmission is requested of a data unit transmitted using the semi-persistent radio resource. The ARQ process identifier associated with the semi-persistent resource is used to match a retransmission of a data unit dynamically scheduled on the communications link with the requested data unit retransmission. In a preferred example embodiment, the ARQ process identifier is a hybrid ARQ (HARQ) process, where a retransmitted data unit is combined with a previously-received version of the data unit.

摘要： A mechanism for improved data transmission between units in a telecommunication network, where at least one of the units utilizes multiple transport channels for transmitting data. An acknowledgeable data transmission is started over a first transport channel if no other on-going acknowledgeable data transmission on a second transport channel starts or ends within a pre-defined or assigned transmission period for the first channel. Thereby, unique identification of acknowledgements messages is enabled.

摘要： A method (400) for use in a cellular system with at least one controlling node (110), eNodeB, which controls user terminals, UEs (130), in a cell (120). According to the method, a UE can be in one of at least two different states (410), an idle state, a DRX state, and an "on duration" state. A UE (130) can receive at least a first (420) and a second (425) type of traffic from its eNodeB (110). If (415) the first type of traffic is received by a UE during an on duration period, the UE assumes the idle (DRX) state at the end of the on duration period, and if (430) the second type of traffic is received by the UE during an on duration period, the UE prolongs the current on duration period by a certain amount of time.

摘要： A node implementing an RLC (Radio Link Control) entity and being for use in a mobile communications system transmits a sequence of RLC SDUs (SDU = Service Data Unit) towards a peer node. As a result of re-establishment of an RLC entity not all SDUs may have been received. The peer notifies the node which is the next SDU that the peer expects to receive (by transmitting the next SDU number to the node). The node resumes transmission from that SDU onwards. This may or may not lead to re-transmission of SDUs transmitted before the RLC re-establishment. As an alternative, the peer does not notify the node of the next SDU that it expects to receive, but instead the node retransmits any unacknowledged SDUs, together with the SDU number of the first retransmitted SDU. The peer then discards any duplicate SDUs. Both variants enable lossless data transfer wbilst avoiding duplication.
摘要翻译：实现RLC（无线电链路控制）实体并且用于移动通信系统的节点向对等节点发送RLC SDU序列（SDU =服务数据单元）。作为重新建立RLC实体的结果，不是所有的SDU可能已被接收。对等体通知节点，它是对等体期望接收的下一个SDU（通过向节点发送下一个SDU号码）。该节点从该SDU向后恢复传输。这可能导致或可能不导致RLC重新建立之前传输的SDU的重传。作为替代，对等体不通知其期望接收的下一个SDU的节点，而是节点与第一重传的SDU的SDU号码一起重传任何未确认的SDU。对等体然后丢弃任何重复的SDU。这两种变体都能够在避免重复的同时实现无损数据传输。

摘要： Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR2) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.

摘要： Method and apparatus in a communication unit (400) employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received RX sub-frames, in TX sub-frames available for transmission. An obtaining unit (402) in the communication unit receives allocation parameters (P) for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit (404) in the communication unit then schedules feedback reports (FR) in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.
