Abstract:
1. A method for use in a radio network controller of a wireless communication network that comprises at least one user equipment (UE) capable of communicating with a network unit, said UE and said network unit being configured to have one or several receive and/or transmit antennas, said method comprising: receiving from said network unit at least one report indicating a recommendation on a transmission/reception mode to be used by said UE in said network, wherein said recommendation is based on at least one of: signal to interference and noise ratio (SINR) estimates, channel rank estimates, and output power levels; deciding on a transmission/reception mode to be used by said UE by selecting between a non-multiple input multiple output (MIMO mode and a multiple input multiple output (MIMO mode; informing said network unit, in a signaling message, a decision on the selected transmission/reception mode to be used by said UE, wherein said network unit informs said UE of the decision, based on said signaling message, and wherein said signaling message is a Layer 3 (L3) signaling message comprising a NodeB Application Part (NBAP) signaling message from said network control unit to said network unit and a Radio Resource Control (RRC) signaling message for sending from said network unit to said UE.
