摘要： A method, in a network in which a handover of a wireless device occurs, the User Equipment (UE) moving from a source cell to a target cell, is provided. The method comprises at least: (at the source cell) determining a sequence number (SN) related to a data packet; forwarding at the RLC layer data packets to the target cell, the data packets being previously sent to the UE but unacknowledged by the UE and having SNs inferior to the determined sequence number; and sending the determined SN to the target cell. The method further comprises (at the target cell) sending a first data packet with the determined SN to the wireless device; the determined SN being a demarcation line for using different encryption keys. The UE will decrypt the received data packets having SNs inferior to the determined SN using an encryption key from the source cell; and decrypt received packets having SNs superior to the determined SN using an encryption key from the target cell.

摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. Acknowledgement channels for the mobile terminals are assigned to channel groups based on a predetermined assignment criteria. All acknowledgment channels in the same channel group receive acknowledgements on the same downlink resources (e.g., resource elements in OFDM system). A required transmit energy for each channel is determined. If the total required transmit energy for all channels exceeds an available transmit power, the allocated transmit energy for each channel is either scaled down so that the total actual transmit power for all acknowledgment channels is equal to the available transmit power, or some acknowledgment channels are not transmitted..

摘要： In one embodiment, a method of operating a radio access node is provided. The method comprises determining whether support from a secondary cell is required for a wireless device to communicate with the radio access node, and, in response to determining that support from the secondary cell is required, calculating a modified channel condition outer-loop value for the secondary cell; and using the modified channel condition outer-loop value in an initial activation decision step for the secondary cell. The initial activation decision step may comprise activating the secondary cell in response to determining that the sum of a device reported channel condition value and the modified channel condition outer-loop value is above an activation threshold. Corresponding devices, computer programs and radio access nodes adapted to carry out the methods provided are also disclosed.

摘要： A radio user equipment (UE) mobility status is determined in a communications node. UE mobility status measurements associated with the UE communicating over a radio channel are performed. The UE mobility status corresponds to a degree of variation of the radio channel over time. Channel characteristics of the radio channel at a first time and at a second later time are determined. Based on the determined channel characteristics, a channel characteristic error metric is determined and compared to a predetermined threshold. The UE mobility status is determined based on one or more iterations of the threshold comparison.
