METHODS AND ARRANGEMENT FOR HANDLING A DATA TRANSFERRAL IN A CELLULAR NETWORK

摘要

A method in a first base station (105) for handling a data transferral in a cellular network (100) is provided. The first base station (105) serves a user equipment (125) via a first cell (115). When the first base station (105) obtains an indication that a second cell (120) provides a coverage for the user equipment (125) the first base station (105) sends a message to a second base station (110) serving the second cell (120). The message commands the second base station (110) to prepare for receiving the uplink data from the user equipment (125) via the second cell (120). The first base station (105) also sends a request to the user equipment (125). The request commands the user equipment (125) to prepare for sending the uplink data both via the first cell (115) and via the second cell (120) in respective separate intra frequency transmissions.
