摘要： The present invention relates to a node and a method thereof for a mobile telecommunication network connectable to a controlling node and wirelessly connectable to mobile terminals. The node is adapted to have an uplink connection to a mobile terminal, wherein the mobile terminal is adapted to have a second uplink connection to at least a second node such that data transmitted from the mobile terminal may be received at the node and at the at least the second node. The node comprises means for estimating whether data transmitted from the mobile terminal received at the at least the second node is received stronger than the data received at said node and means for discarding data received from the mobile terminal if it is estimated that the data is received stronger at the at least the second node than the data received at said node.

摘要： Methods for efficiently controlling the retransmission of data units in a wireless telecommunication system, wherein multiple complementary feedback mechanisms are used to control retransmission. A receiver attempts to decode each received data unit. If a data unit is successfully decoded, the receiver transmits positive feedback to the transmitter; if a data unit is not successfully decoded, the receiver transmits negative feedback to the transmitter. In all cases, the transmitter employs at least first and second feedback mechanisms for transmitting the positive and negative feedback. In an exemplary embodiment, acknowledgement (ACK) and non-acknowledgement (NACK) messages are sent in response to the receipt of each data unit on a first unreliable channel and Status Messages identifying sequence numbers of particular data units are periodically transmitted on a second reliable channel; the receiver preferably removes data units from its transmit window only upon receipt of a Status Message indicating successful decode.

摘要： A system, method and node of downlinking transmissions to an unsynchronized UE in a telecommunications network. The method begins by a node in the network requesting synchronization of the UE with the network. A first transmission of data is sent from the node to the UE prior to synchronization of the UE. The UE then synchronizes with the network by the UE performing a Random Access procedure with the node, thereby triggering a time alignment command from the node to the UE to synchronize the UE with the network. A second transmission of data is then sent from the node to the UE after the UE is synchronized. A response feedback message is sent to the node from the UE. The message is a cumulative feedback message of the first transmission of data and the second transmission of data. Thus, data may be transmitted prior to synchronization of the UE.

摘要： The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.
