摘要： In a method and a device for requesting Channel Quality Indication (CQI) reports from a mobile station of a cellular radio system, the CQI reports are requested in response to a measured Block Error Rate (BLER) of transmissions from the mobile station. In accordance with one embodiment of the present invention a CQI report is requested if the BLER of the mobile station is above a predetermined threshold value C. The threshold value C can be set to a value related to the BLER target. In particular the value C can be set to the same value or as a value close the BLER that is targeted to try to adapt the CQI report request to how well the base station knows the channel. It can also be set higher or lower to also consider how much CQI reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink.

摘要： The present invention relates to a method and to a transceiver (400) for detecting HARQ transmission failure in a telecommunications system. The transceiver (400) is arranged to execute a HARQ process which is used to generate a transmission of data units to e.g. a eNodeB. The transceiver is also arranged to determine when a maximum number of transmission attempts is reached and when this occurs to flush a HARQ buffer associated with the HARQ process and to detect that a HARQ transmission failure has occurred when the last HARQ feedback received for the current HARQ process is not a HARQ ACK.

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： Techniques for controlling synchronous HARQ retransmissions are disclosed, in which non-adaptive retransmissions scheduled for a first transmission time interval are automatically deferred to a later transmission time interval in the event that a control message prohibiting the retransmission during the first transmission interval is received. In an exemplary method, a NACK message is received (320) in response to a previous data transmission corresponding to a stop-and-wait HARQ process, and a synchronous HARQ retransmission is scheduled (330) for a first transmission interval in response. A control message indicating that data for the stop- and-wait HARQ process may not be sent during the first transmission interval is received, and the synchronous HARQ retransmission is automatically deferred (350) to a second transmission interval, responsive to the control message. An explicit grant is not required to trigger the retransmission during the second transmission interval.

摘要： The present invention relates to a method and apparatus for requesting scheduling of resources to be used for uplink communication of data in a communications system. If the repeated transmission by a user equipment of scheduling requests on an uplink control channel is determined to be unsuccessful, a random access transmission on a random access channel is initiated as a fallback procedure.

摘要： A method and apparatus for reducing handover interruptions when a mobile device executes handover including a random access procedure is described herein. When handover is desirable, a time offset associated with a random access opportunity is determined. The time offset relates the timing of the next random access opportunity to the frame timing of a target access point. Based on the time offset, a network element, e.g., the mobile device, a serving access point, or a mobility management entity, determines a handover start time. Handover is executed at the determined start time to generally align the beginning of the handover execution with the beginning of the next random access opportunity, and therefore, to reduce handover interruption.
摘要翻译： 这里描述了当移动设备执行包括随机接入过程的切换时减少切换中断的方法和装置。 当需要切换时，确定与随机访问机会相关联的时间偏移。 时间偏移将下一个随机访问机会的定时与目标接入点的帧定时相关联。 基于时间偏移，诸如移动设备的网络元件，服务接入点或移动性管理实体确定切换开始时间。 在确定的开始时间执行切换，以将切换执行的开始与下一个随机访问机会的开始对齐，并且因此减少切换中断。
