Abstract:
1. A method in a wireless communication system comprising a user equipment, an anchor network station and at least one assisting network station, wherein the user equipment simultaneously transmits the same data to the anchor and assisting network stations; the anchor and assisting network stations each receive the data and transmit an acknowledgement of the data to the user equipment in response; and the at least one assisting network station also forwards the data to the anchor network station, wherein a re-transmission process is used, in which each network station sends a positive acknowledgment if the data is decodable, or a negative acknowledgment if the data is not decodable, the negative acknowledgment acting as a request for re-transmission; and wherein a predetermined round trip time between sending the data in a first transmission and receiving an acknowledgment for the transmission does not allow sufficient time for the data forwarding, so that the forwarded data is to be combined in the anchor network station with data from the first transmission and at least one re-transmission from the user equipment to the anchor network station.
