摘要： The invention relates to a technique for uplink data transmissions in, e.g., mobile networks. A method embodiment for performing the technique in a transmitter (122) comprises the steps of allocating, for a first transmission (T1′) as the transmission power for an uplink control channel (UCOCH), the smaller of an available transmission power and a desired transmission power for the uplink control channel; and allocating, for at least one subsequent transmission (T2′) triggered by a feedback indication (128), zero transmission power to 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： 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.
摘要翻译：支持从多个逻辑信道到单个MAC-d流的数据的UTRAN MAC-d复用，同时减少开销并在MAC-d PDU长度内实现八位位组对准。在一个实施例中，消除了复用的MAC-d PDU的C / T字段，并且复用到MAC-d流中的逻辑信道被映射到至少节点B（并且优选地在UE中的MAC-hs PQ）好）。在其他实施例中，C / T字段被保留，并且八位字节对齐的长度指示符从RNC发送到UE。在一个实施例中，长度指示符通过填充MAC-d PDU进行八位字节对齐。在另一个实施例中，从RNC到UE的路径中的发射机和接收机被配置有偏移量以添加到长度指示符以实现八位字节对准。填充或偏移量为（8-n）位，其中n = C / T域中的位数。

摘要： Methods and apparatus for processing error control messages, such as RLC ARQ control messages, are disclosed. An exemplary method comprises signaling a medium access controller (MAC) that link resources are needed for transmitting data, receiving an indication from the MAC that link resources for transmitting the data are scheduled, and generating an error control message after receiving said indication, based on a current error control status. The error control message is then forwarded to the MAC for transmission. Because the generation of an error control message is delayed until resources for its transmission are scheduled, the queuing of stale control messages is avoided.

摘要： A procedure for synchronization of re-configuration of RRC procedures between the radio base station and the UE is achieved by associating a new configuration to be used by a UE with an additional UE identity. The UE is normally identified by a first UE identity, but is informed in a re-configuration message that the UE also has the additional UE identity. The UE is identified by the additional UE identity when the new configuration is to be activated. Hence, when the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.

摘要： The present invention provides a stall avoidance mechanism that may be used alone or in conjunction with an ambiguity avoidance mechanism in an ARQ protocol. Both mechanisms decrease data delays and increase data throughput rates. Stall avoidance is accomplished by determining whether a stall condition exists with respect to receiving a missing data unit. In one example, only a single timer is needed to avoid stalls. Retransmission ambiguities may be avoided using a retransmission window in the transmitter and/or a receive window in the receiver. Although each mechanism may be used independently of the other, a preferred example embodiment uses a stall avoidance timer, a retransmission window in the transmitter, and a receive window in the receiver.
摘要翻译：本发明提供了可以单独使用或与ARQ协议中的模糊度回避机制结合使用的失速回避机制。这两种机制都可以减少数据延迟并提高数据吞吐率。通过确定关于接收丢失的数据单元是否存在失速条件来实现失速回避。在一个示例中，仅需要一个定时器来避免停顿。可以使用发射机中的重传窗口和/或接收机中的接收窗口来避免重传模糊。虽然每个机制可以独立于另一个使用，但是优选示例性实施例使用失速避免定时器，发送器中的重传窗口和接收器中的接收窗口。
