Problems solved by technology
[0008] Furthermore, downlink transmissions are typically subject to limitations of receive antenna elements at the user equipment (UE)
Computational requirements and loss of diversity are two key issues due to limited antenna space on the UE

Embodiment Construction
[0038] Figure 1a Shown is a block diagram of an embodiment of an apparatus 100 for providing first data detection information on a first data signal of a first mobile transceiver and second data detection information on a second data signal of a second mobile transceiver. The device comprises means 110 for communicating with a first mobile transceiver for receiving from the first mobile transceiver a first received signal vector, the first received signal having been received by the first mobile transceiver from the base transceiver station. The device 100 further comprises means 120 for communicating with a second mobile transceiver for receiving from the second transceiver a second received signal vector, the second received signal having been received by the second mobile transceiver from the base transceiver station. In other words, the device 100 may determine or detect data detection information on two data signals dedicated to two different users by receiving received s...

An concept for providing first data detection information on a first data signal of a first mobile transceiver and second data detection information on a second data signal of a second mobile transceiver, comprising means 110 for communicating with the first mobile transceiver for receiving a first receive signal vector from the first mobile transceiver, the first receive signal having been received from a base station transceiver by the first mobile transceiver, and means 120 for communicating with the second mobile transceiver for receiving a second receive signal vector from the second transceiver, the second receive signal having been received from the base station transceiver by the second mobile transceiver. Moreover the concept makes use of means 130 for determining the data detection information on the first data signal and data detection information on the second data signal based on the first receive signal vector and the second receive signal vector and means 140 for providing the data detection information on the first data signal to the first mobile transceiver and for providing the data detection information on the second data signal to the second mobile transceiver.
Description
technical field [0001] The present invention relates to data signal detection in received radio signals, and more particularly, but not exclusively, to data signal detection in Multiple Input Multiple Output (MIMO for short) systems. Background technique [0002] Multiple-Input Multiple-Output (MIMO) Antenna Technology Can Significantly Increase Data Rates by Exploiting Spatial Multiplexing and / or Achieve Additional Diversity Gain by Applying Space-Time Coding, Wireless Personal Communications, Vol. 6, No. 3, March 1998 "On limits of wireless communications in a fading environment when using multiple antennas" by Foschini, G.J. and Gans, M.J., pp. 311-335; European Transactions on Telecommunications Vol. 10, No. 6, Nov. 1999, pp. 585-595 "Capacity of multi-antenna Gaussian channels" by Telatar, I.E.; "A simple transmit diversity technique for wireless communications". However, with the increasing demand for higher data throughput and higher spectral efficiency, new system ...
