Publication number: 20040120289Abstract: The present invention relates to a method in a communication system that is adapted to provide communication channels for transmission of information to user equipment in time frames such that information to a plurality user equipment can be multiplexed into a time frame. The method comprises receiving signals from transmitting elements of the communication system in at least two user equipment, processing the received signals at said at least two user equipment to generate respective feedback signals, receiving the feedback signals at a controller associated with the transmitting elements of the communication system, and processing the feedback signals at the controller for determining how to multiplex information into time frames in further transmissions to said at least two user equipment. The determination is based on the feedback signals and a resource allocation scheme that allows use of same resource for transmissions to the at least two user equipment if a predefined condition is met.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Inventors: Jyri K.

Patent number: 6542556Abstract: A method and apparatus for space-time coding signals for transmission on multiple antennas. A received input symbol stream is transformed using a predefined transform and transmitted on a first set of N antennas. The same input symbol stream is then offset by M symbol periods to generate an offset input symbol stream. The offset input symbol stream is then transformed using the predefined transform and transmitted on a second set of N antennas. A third through Xth set of N antennas may be utilized for transmission by successively offsetting the offset input symbol stream by an additional M symbol periods for each additional set of N antennas used, before performing the transform and transmitting on the additional set of N antennas.Type: GrantFiled: March 31, 2000Date of Patent: April 1, 2003Assignee: Nokia Mobile Phones Ltd.Inventors: Kiran Kuchi, Jyri K.
