摘要： A mobile station is configured to support handover from a source base station to a target base station. The mobile station receives signaling from the target base station that indicates Packet Data Convergence Protocol (PDCP) protocol data units which have been successfully received at the target base station. In response, the mobile station generates further PDCP protocol data units for missing PDCP service data units from corresponding PDCP service data units buffered at the mobile station. The generating comprises using a different header compression state from that which was used for the missing PDCP service data units and ciphering specific to a connection with the target base station. The mobile station transmits the further PDCP protocol data units to the target base station.

摘要： The present solution relates to a method in a user equipment for configuring a cell change procedure to be used for handover in a wireless communication network. The user equipment is situated in a serving cell and comprises an active set of cells. The active set of cells comprises a list of cells to which the user equipment can move from the serving cell. The user equipment sends a request to a network controller comprised in the wireless communication network to add at least one further cell to the active set. The user equipment then receives the requested active set update from the network controller. The received active set update comprises the at least one further cell to be added to the active set and a list of cells to which a modified cell change procedure shall be used for handover. A neighbour cell which is stronger than a current serving cell is detected. This detected stronger neighbour cell is matching with the received list of modified cell change procedure cells, and the modified cell change procedure for the handover to the stronger neighbour cell is applied if the stronger neighbour cell is found matching a cell on the list.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

摘要： A wireless communication device is configured for use in a wireless communication system. The device in this regard is configured to receive a command that commands the device to perform a link switch from a source link to a target link responsive to fulfillment of a condition. The command may indicate a target link configuration relative to a source link configuration. The device is also configured to store information from which the target link configuration indicated by the command is determinable irrespective of any change to the source link configuration occurring after receipt of the command. In some embodiments, the device is configured to, responsive to fulfillment of the condition, perform a link switch from the source link to the target link using the target link configuration as determined from the stored information.

摘要： A method of operation of a wireless communication device to perform handover from a source cell to a target cell in a wireless communication system is provided. The wireless communication device performs (202) a beam tracking procedure for one or more neighbor cells to provide, for each neighbor cell, a list of tracked beams for the neighbor cell. The wireless communication device receives (212) a handover command from a source radio access node that instructs the wireless communication device to perform a handover from a source cell served by the source radio access node to a target cell served by a target radio access node. The target cell is one of the one or more neighbor cells for which the beam tracking procedure is performed. The wireless communication device then selects (214) a beam of the target cell from the list of tracked beams for the target cell based on random access resource configuration and/or a quality threshold. The wireless communication device then performs (216) random access on the selected beam.
