Abstract
A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords c i where i is a unique codeword index for each codeword ci. Each codeword defines weighting factors to apply to the MIMO signals and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets S1 for each codeword c1 of the codebook C. Each codeword subset S1 defines L codewords cj which are selected from all the codewords ci in the codebook C. The codewords cj in a codeword subset S1 are the L codewords in the entire codebook that best correlate with the corresponding codeword ci.

determining a subset of matrices of predefined weighting factors corresponding to the first codebook index;
selecting, at a subsequent second time, a second matrix of predefined weighting factors from the subset of matrices of predefined weighting factors; and
transmitting a first subset index for the second matrix of predefined weighting factors.
2. The method of claim 1, further comprising:
selecting, at a subsequent third time, a third matrix of predefined weighting factors from the subset of matrices of predefined weighting factors; and
transmitting a second subset index for the third matrix of predefined weighting factors.
3. The method of claim 1, further comprising:
determining, at a subsequent third time, that a third matrix of predefined weighting factors is to be selected from the codebook;
selecting the third matrix of predefined weighting factors from the plurality of matrices in the codebook; and
transmitting a second codebook index identifying the third matrix of predefined weighting factors.

determining a second subset of matrices of predefined weighting factors corresponding to the second codebook index;
selecting, at a subsequent fourth time, a fourth matrix of predefined weighting factors from the second subset of matrices of predefined weighting factors; and
transmitting a second subset index for the fourth matrix of predefined weighting factors.
5. The method of claim 3, wherein determining, at the subsequent third time, that the third matrix of predefined weighting factors is to be selected from the codebook is determined based on one or more of a counting of feedback instances, transmission instances, time periods, and the extent to which channel conditions are changing.
6. The method of claim 1, wherein the subset of matrices of predefined weighting factors does not comprise the first matrix of predefined weighting factors.
7. The method of claim 1, wherein the subset of matrices of predefined weighting factors comprises the first matrix of predefined weighting factors.
8. An apparatus for providing wireless communications feedback, the apparatus comprising:
transmit circuitry;
a memory storing software instructions; and
one or more processors communicatively coupled to the transmit circuitry and the memory, the one or more processors configured to execute the software instructions, wherein, in executing the software instructions, the one or more processors cause the apparatus to:
select, at a first time, a first matrix of predefined weighting factors from a plurality of matrices in a codebook;
transmit, via the transmit circuitry, a first codebook index identifying the first matrix of predefined weighting factors;

transmit, via the transmit circuitry, a second codebook index identifying the third matrix of predefined weighting factors.
11. The apparatus of claim 10, wherein, in executing the software instructions, the one or more processors are further configured to cause the apparatus to:
determine a second subset of matrices of predefined weighting factors corresponding to the second codebook index;
select, at a subsequent fourth time, a fourth matrix of predefined weighting factors from the second subset of matrices of predefined weighting factors; and
transmit a second subset index for the fourth matrix of predefined weighting factors.
12. The apparatus of claim 10, wherein determining, at the subsequent third time, that the third matrix of predefined weighting factors is to be selected from the codebook is determined based on one or more of a counting of feedback instances, transmission instances, time periods, and the extent to which channel conditions are changing.
13. The apparatus of claim 8, wherein the subset of matrices of predefined weighting factors does not comprise the first matrix of predefined weighting factors.
14. The apparatus of claim 8, wherein the subset of matrices of predefined weighting factors comprises the first matrix of predefined weighting factors.
15. A method of receiving feedback from a wireless receiver, the method comprising, at the wireless transmitter:
receiving, at a first time, a first codebook index identifying a first matrix of predefined weighting factors, wherein the first matrix of predefined weighting factors is one matrix of a plurality of matrices in a codebook;
determining a subset of matrices of predefined weighting factors corresponding to the first codebook index;
receiving, at a subsequent second time, a first subset index, wherein the first subset index identifies a second matrix of predefined weighting factors from the determined subset of matrices of predefined weighting factors.
16. The method of claim 15, further comprising:
receiving, at a subsequent third time, a second subset index, wherein the second subset index identifies a third matrix of predefined weighting factors from the subset of matrices of predefined weighting factors.
