Abstract
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.

43. A method in a first base station for handling a data transferral in a cellular network, which first base station serves a user equipment via a first cell in the cellular network, the method comprising:
-
when obtaining an indication that a second cell in the cellular network provides a coverage for the user equipment, sending a message to a second base station serving the second cell, which message commands the second base station to prepare for receiving the uplink data from the user equipment via the second cell, and sending a request to the user equipment, which request commands the user equipment to prepare for sending the uplink data both via the first cell and via the second cell, and wherein the request further commands that the uplink data is to be sent via first cell and via the second cell in respective separate intra frequency transmissions. - View Dependent Claims (44, 45, 46, 47, 48, 49)
