Claim:
1. A method of communicating data between a first base station and a mobile terminal, the method comprising: in response to determining that the mobile terminal is located in a transition area between two cell border lines, the first base station switching from a dual link mode to an independent link mode in which (i) in the dual link mode, the first base station provides downlink and uplink transmissions to the mobile terminal and (ii) in the independent link mode, the first base station provides downlink transmissions to the mobile terminal and a second base station provides uplink transmissions to the mobile terminal, the first base station selecting the second base station from a plurality of base stations, on the basis of a parameter which is indicative of a path loss for the uplink transmissions from the mobile terminal to the second base station; the first base station sending, to the second base station, a request to handle uplink transmissions from the mobile terminal, said handling of the uplink transmissions comprising scheduling of the uplink transmissions to obtain uplink scheduling information; the first base station receiving the uplink scheduling information from the second base station; and the first base station sending downlink transmissions to the mobile terminal, said downlink transmissions including the uplink scheduling information received from the second base station, wherein the scheduling information includes time-frequency resources, and wherein the mobile terminal is determined to be in the transition area based on RSRP
