摘要： The present invention relates to a method and an arrangement for controlling downlink power in a multi-carrier communication network system. The communication network system comprises communication network nodes (15) communicating with a plurality of user equipments (18) on uplink (17) and downlink (16) carriers over a radio interface. Downlink transmit power control commands are sent on at least one uplink control channel to support power control for a multiple of downlink carriers. Each transmit power control command is assigned a pre-determined code word known by said user equipment (18) and said communication network node (15) and/or different pre-determined slot formats, known by said user equipment (18) and said communication network node (15), are used to integrate different number of transmit power control command based on the number of used downlink and uplink carriers.

摘要： A device receives a measurement report generated by user equipment, and determines whether a serving cell for the user equipment should change from a source cell to a target cell based on the measurement report. The device also configures the source cell and the target cell for the serving cell change when it is determined that the serving cell for the user equipment should change, and transmits, via the target cell, a serving cell change message to the user equipment using a common network temporary identifier. The device further receives, from the user equipment, an acknowledgment of the serving cell change.

摘要： A device (110) receives a radio link control (RLC) protocol data unit (PDU) (740) or service data unit (SDU) (760) to be segmented, defines a padding threshold (840) for a segmentation mechanism, and determines a padding ratio (850) after enhanced dedicated channel transport format combination (ETFC) selection (730). The device selects a first transport block (960) and a second transport block (970) associated with the RLC PDU/SDU (740/760) when the padding ratio (850) is greater than or equal to the padding threshold (840), and generates a modified segmentation of the RLC PDU/SDU (740/760) based on the first and second transport blocks (960/970) when a padding ratio (RTB) associated with the first and second transport blocks (960/970) is less than the padding threshold (840) and a size ratio (STB) associated with the first and second transport blocks (960/970) is within a size threshold (980).

摘要： Out-of-sync and in-sync detections and downlink power control by UTRAN (10) user equipment (22) are improved in Continuous Packet Connectivity mode featuring discontinuous UL DPCCH transmission by requiring all F-DPCH transmissions from a base station (16) to the user equipment (22) to be valid during a UL DTX gated period. Additionally, the user equipment (22) receives and considers all F-DPCH transmissions during the UL DTX gated period, for power control, out-of-sync and in-sync detections. If the user equipment (22) detects an out-of- sync condition, it may immediately transmit a scheduling request to notify the network (10), temporarily or permanently annulling the discontinuous UL DPCCH transmission.

摘要： The inventors have envisioned a multihop network scenario in which nodes are equipped with advanced multi-antenna arrangements, and recognized the advantage of exploring the presence of such advanced antenna arrangements in multihop network nodes for the specific purpose of determining link cost for routing in the network. Link cost is determined for a wireless link between a pair of nodes in the network based on multi-channel characteristics between the nodes, where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels. These multi-channel characteristics may for example be determined based on explicit channel matrix estimation and/or the number of transmit and receive antennas or other information on the antenna capabilities of the involved nodes. The determined link cost information may subsequently be used together with additional routing cost information for route determination, and packet forwarding.

摘要： The invention relates to a method and an arrangement for obtaining efficient radio resource utilization in a communication network comprising a communication network entity transmitting data on a downlink channel over a radio interface to one or more user equipments, each of which is transmitting data on an uplink channel to said communication network entity over said radio interface. The communication network entity receives transmit power control (TPC) commands on said uplink channel and, further, monitors a channel quality indicator (CQI) on said uplink channel from said user equipment in order to obtain channel quality indicator measurements. If there is a channel quality indicator available, the communication network entity calculates a required downlink power. Otherwise, the communication network entity decodes said received transmit power control commands. Thereafter said transmission power is adjusted either based on the calculated downlink power or based on the decoded transmit power control commands in order to obtain efficient radio resource utilization.
