Abstract:
1. A method of setting antenna transmission weightings of user equipment in a wireless telecommunication network, said user equipment being operable to transmit on at least two antennas and operable to communicate simultaneously with at least two base stations from an active set associated with said user equipment, said method comprising: receiving preferred antenna transmission weightings from said at least two base stations in said active set; calculating an indication of compromise antenna transmission weightings which minimise a difference between said indication of compromise antenna transmission weightings and said preferred antenna transmission weightings, said calculating further comprising assigning a weighting to said preferred antenna transmission weightings from each base station in said active set, said weighting being determined based upon an indication of a relative importance of each base station in said active set to operation of said user equipment within said wireless communication network; and, setting said antenna transmission weightings in accordance with said indication of compromise antenna transmission weightings; wherein said calculating comprises: minimising a mean squared distance between the indication of compromise antenna transmission weightings and the preferred antenna transmission weightings received from the base stations in said active set; wherein said preferred antenna transmission weightings comprises an indication of an amplitude shift between transmissions of a signal on said at least two antennas; and wherein said preferred antenna transmission weightings comprises an indication of antenna selection.
