`
`SYSTEM AND METHOD FOR CLOSED LOOP MIMO PRE-CODING AND
`F EEDBACK
`
`The present invention generally relates to closed loop MIMO (Multiple Input Multiple
`Output) pre-coding and feedback, and more specifically to closed loop MIMO pre-coding
`and feedback for purposes of the IEEE 802.16(e) and IEEE 802.1 l(n) standards.
`
`BACKGROUND OF THE INVENTION
`
`As will be apparent to one of skill in the art there are numerous problems with the current
`IEEE 802.16( e) standard that need to be resolved including:
`
`[1] MIMO channel feedback bandwidth reduction
`[2] Antenna group selection
`[3] MIMO channel feedback ageing
`[4] Vector quantization for the MIMO channel
`[5] MIMO feedback flow control associated MAC design
`[ 6] Feedback channel design
`[7] Feedback STC coding and channel sounding
`
`While several solutions have been proposed in IEEE802.16(e) and IEEE802.ll(n) for the
`closed loop MIMO pre-coding transmission, they are not practical for the following
`reasons:
`
`[I] The Hausholder transform based SVD beam former feedback: The problem
`with this approach is that it is too complex for mobile channel realization
`
`[2] Single user based fixed sub-channel allocation: The problem with this
`approach is that it has 2-3 times capacity loss compared to multi-user diversity
`
`[3] Receiver based vector channel quantization: The problem with this approach
`is that it exponentially increases terminal complexity
`
`A need exists therefore for an improved system and method for enabling closed loop
`MilvIO pre-coding and feedback.

`
`As shown in Figure 1 particular embodiments of the invention can be largely grouped
`into four categories of algorithms for purposes of illustration:
`
`• Multi-User Selection (Embodiment 1.0): includes algorithms for organizing users,
`organizing antennas and selecting sub-bands;
`
`• Quantized MIMO Channel Feedback (Embodiment Group 2.0): includes
`algorithms for facilitating feedback from a terminal to a BTS;
`
`• MAC Layer (Embodiment 3.0): includes algorithms for the overall operation of
`the JEEE 802.16(e) or 802.1 l(n) environment
`
`• Feedback channel for MIMO channel information MIMO (Embodiment 4.0):
`includes the feedback channel structure with the channel sounding capability and
`space time coding on the feedback channel.
`
`In accordance with an embodiment of the invention Embodiments 1.0 and 3.0 occurs
`predominately within an associated BTS, Embodiment 2.0 predominately within an
`associated terminal, and Embodiment 4.0 occurring in both.
`
`Regarding the sub-Embodiments of Embodiment 2.0 (2.1 and 2.2) one of skill in the art
`will appreciate that these algorithms are generally alternative to each other and need not
`co-exist. Similarly their respective sub-Embodiments are alternatives and need not co­
`exist.
`
`In accordance with an embodiment of the invention the sub-Embodiments of
`Embodiment 4.0 co-exist.
