摘要： The teachings presented herein enable a user terminal to perform a fast recovery from a radio link failure. In one aspect, the improvement in recovery time is achieved by commanding or otherwise causing the user terminal to perform radio link failure (RLF) recovery at a cell that is known to possess the user context, while considering that this cell should yield good radio conditions (if not the best) to the user terminal. A cell may be predefined for use by the user terminal in recovering its radio connection. Based on providing signal strength thresholds to the user terminal, for use in determining whether to use a predefined cell for reconnecting to the network, the user terminal attempts RLF recovery first in the predefined cell. By providing user context to the predefined cell in advance of a recovery attempt by the user terminal, the time for recovery is lessened. Note that the user terminal also may infer which cells are preferred.

摘要： A method of operating a base station node (21) comprises obtaining an indication of degradation of a radio link connection between the base station node and the user equipment unit (UE) which is carried by the a high speed packet channel (HSDPA). In accordance with the distance indication, the transmission priority for the radio link connection is modified. Preferably the indication of degradation is a distance indication of distance of a user equipment unit (23) involved in the radio link connection from the base station node (21). The transmission priority can be modified for one or both of downlink and uplink transmissions for the user equipment unit (UE). Preferably the transmission priority is modified for the radio link connection, e.g., for the user equipment unit (UE), as a function of the indication.

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： The invention relates to a method (90) in a user equipment (4) for reporting a downlink channel quality in a communication system (1) comprising a first radio access technology system (2) and a second radio access technology system (3). The user equipment (4) is in connection with a primary serving cell on the first radio access technology system (2) and with a secondary serving cell on the second radio access technology system (3). The method (90) comprises: determining (110) channel quality for the second radio access technology system (3) using an indicator format of the radio access technology of the second radio access technology system (3); mapping (120) an indicator of the channel quality having the indicator format of the second radio access technology to an indicator format used for channel quality indicators in the first radio access technology system (2); and transmitting (130) the indicator of the channel quality for the second radio access technology system (3) to the communication system (1) using the indicator format of the first radio access technology on an uplink carrier of the first radio access technology system (2). The invention also relates to a user equipment, methods in a network node and a network node.

摘要： When a user equipment (UE) is in a CONNECTED state with a base station of a wireless network and is also in a discontinuous reception (DRX) mode, a DRX parameter such as DRX period for the UE is compared with a threshold. If the DRX parameter is at or below the threshold, the UE applies a network controlled mobility mode with UE assist where the network controls handover of the UE to another cell. If the DRX parameter is above the threshold, the UE applies a UE controlled mobility mode in which the UE is free to select a best cell. In this way, DRX benefit of reduced power consumption is maintained while the time period in which the UE is unreachable is minimized.

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： 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： In a method and device the TCP load offered in the uplink is manipulated such that an offered load asymmetry is achieved. Using such an arrangement it is possible to compensate for a link asymmetry when uplink and downlink connections are sharing the same uplink buffer in order to increase performance of the downlink. The method and device are capable of increasing the download performance both in the case when TCP connections are terminated in a different device than the terminal where the link layer is terminated, as well as when the TCP connections are terminated in the same device as the link-layer.
