摘要： The invention proposes a novel method for handling acknowledgement messages between a first protocol layer (L1) and a second protocol layer (L2) in a network node operating as a relay network node (RN). The first protocol layer (L1) is lower with respect to the second protocol layer (L2). The acknowledgement messages (ACK) are related to Automatic Repeat Request (ARQ) processes and the Relay Node (RN) is engaged in an Uplink transmission towards a network access node (eNB). The method comprises a step (10) of receiving a first grant indication by said network access node (eNB) that an Uplink Transmission is granted at said first protocol layer entity (L1) and a step of sending (100) towards said second protocol layer entity (L1) an indication of Acknowledgement (ACK) after receiving a first grant indication. The invention also proposes a corresponding Relay Node (RN).

摘要： The present invention relates to a method in a receiving node and a sending node of a wireless communications system for enabling and disabling integrity protection of at least one data radio bearer between the sending node and the receiving node. The method in the receiving node comprises, following a successful connection re-establishment between the sending node and the receiving node, receiving (710) a connection reconfiguration message from the sending node, the connection reconfiguration message comprising an indicator indicating which ones of the at least one data radio bearers that shall have enabled integrity protection. It also comprises enabling (720) integrity protection of packets on the at least one data radio bearer indicated by the indicator, and disabling (730) integrity protection of packets on the rest of the at least one data radio bearers.

摘要： A method and arrangement for estimating the current channel quality for a data transfer in a mobile network. In a sending system entity, a channel quality estimate (CQE) associated with a data transfer to a receiving system entity in a mobile communication network is adjusted. One or more probing packets are communicated 400 between the sending system entity and the receiving system entity, each probing packet being formatted according to a predefined combination of transmission parameters. Furthermore, is a Channel State Information (CSI) report received 404 from the receiving system entity, and the CQE is adjusted 406 based on the CSI report and which probing packets have been successfully communicated. By sending a sequence of probing packets, each formatted according to a predefined combination of transmission parameters, and not waiting for each packet to be acknowledged, a fast and accurate estimation of the current channel quality is achieved.

摘要： A method of estimating path loss for a channel between a user equipment and a base station of a wireless communication system, the method performed at the base station and comprising the steps of: measuring (302) a signal power PSDrx for a received signal transmitted from the user equipment to the base station on the channel; and estimating (304) a path loss PL*, based on the measured signal power PSDrx and a path loss compensation value α associated with the base station. A base station and a computer readable medium is also described.

摘要： A method in a user equipment for handling a scheduling request trigger is provided. The user equipment comprises a buffer. After receiving (501) data arriving into the buffer to be transmitted to a base station, the user equipment generates (503) a scheduling request trigger. The scheduling request trigger is pending until it is cancelled, and is triggered directly or indirectly by the arrived data. The user equipment cancels the pending scheduling request when a Medium Access Control Packet Data Unit, MAC PDU, is assembled for transmission and including a buffer status report, the buffer status report accounting for the data that triggered the scheduling request.

摘要： Disclosed are a method and arrangement in a user equipment for transmitting scheduling requests to a base station. The base station is adapted to serve the user equipment. The user equipment is configured to transmit scheduling requests to the base station only at certain predetermined scheduling request opportunities. The method comprises triggering a scheduling request transmission, transmitting a scheduling request to the base station at the next occurring scheduling request opportunity, starting a scheduling request prohibiting timer and prohibiting any further scheduling request retransmission at future scheduling request opportunities while the scheduling request prohibiting timer is running. Also disclosed are a corresponding method and arrangement in a base station.
