Abstract: A method in a receiving node for sending an acknowledgement/not acknowledgement “ACK/NACK” feedback report of received data units over a radio link is provided. When the receiving node have received (301) data units in a number of subframes over a first radio link from a sending node, it creates (302) an ACK/NACK feedback report. The report is compressed such that it comprises one single ACK/NACK feedback relating to the data units in the number of received subframes, and the report comprises an indicator indicating said number of received subframes. The sending node then transmits (303) the created ACK/NACK feedback report to the sending node over a second radio link. The feedback report renders it feasible for the sending node to decide whether a retransmission of any subframe is required or not based on a comparison of the reported number of received subframes with the known transmitted number of subframes per frame, together with the compressed ACK/NACK feedback report.

Abstract: Upon occurrence of a memory error which is difficult to correct, CPU interrupts a process under execution in response to interrupt signal output from error detection device, and transfers the control to the OS. The OS references attributes of a page stored in a page frame which has suffered the memory error. When read-only is indicated, physical memory management table is updated to set the page frame, which has suffered the error, into a disabled state. Then, page table is updated such that a virtual page stored in the page frame which has suffered the error is not assigned to any page frame, followed by resumption of the execution of the process. After execution of the process is resumed, a page fault process is invoked to store the virtual page which has encountered the memory error in another normal page frame.

Abstract: The present invention relates to methods and arrangements in a wireless communication system, and in particular to uplink outer loop power control. A Node B identifies if a UE from which the Node B receives data is in a predetermined set of power challenged situations. The Node B transmits to the RNC an indication to hold the SIR target of the UE if the UE has been identified to be in a power challenged situation. As a consequence, the uplink outer loop power control (OLPC) procedure in the RNC will not change the SIR target of the UE. This implies that the output power level of the UE remains unchanged as long as the UE remains in the power challenged situation. Thus, user and network performance are improved in the wireless communication system.
