The present invention relates to control signaling in wireless communication systems. In particular, the present invention relates to control signaling in MIMO based communication systems. In the method according to the invention control information is transferred from a base station to at least one user equipment, via a plurality of common pilot channels. A set of unique pilot sequences has been pre-defined, and the base station assigns specific pilot sequences from the set of pilot sequences to specific common pilot channels, forming a pilot sequence assignment pattern representing a specific control information. The user equipment, having knowledge of the relations between pilot sequence assignment patterns and control information, interprets the received pilot sequence assignment pattern as specific control information. The method is particularly well suited for broadcast type control information.
A method of control signaling in a wireless communication network, wherein a radio node transfers control information to at least one second radio node, and wherein a plurality of common pilot channels are available between the first and second radio nodes, the method comprising:
A method in a radio base station of control signaling in a wireless communication network, wherein the radio base station transfers control information to at least one user equipment, and wherein a plurality of common pilot channels are available between the radio base station and the user equipment, the method comprising:
A method in a user equipment of control signaling in a wireless communication network, wherein the user equipment receives control information from a radio base station, and wherein a plurality of common pilot channels are available between the radio base station and the user equipment, the method comprising:
A radio base station adapted to be part of a wireless communication system and to utilize a plurality of common pilot channels in the wireless communication with user equipments, the radio base station provided with multiple antennas and radio communication means for communicating via the multiple antennas, comprising:
The radio base station according to claim 21, wherein the control information comprises a representation indicating control information type and at least one parameter value.
A user equipment adapted to be used in a wireless communication system and to receive a plurality of common pilot channels, the user equipment provided with multiple antennas and radio communication means for communicating via the multiple antennas, comprising:
