Abstract
Briefly in accordance with one or more embodiments in response to receiving a wireless communication signal a non-uniform codebook is generated based at least in part on one or more characteristics of the received wireless communication signal for quantization and communication back to a source of the received signal. The non-uniform codebook may be generated by selecting a suitable uniform codebook based at least in part on the one or more characteristics of the received wireless communication signal and supplementing the uniform codebook with additional codewords to generate the non-uniform codebook.

Claim
1. A method comprising:
receiving a wireless signal from a transmitting device to generate precoding feedback;
determining a precoding matrix indicator (PMI) in response to the wireless signal based at least in part on a hierarchical codebook; and
reporting the PMI back to the transmitting device.
2. A method as claimed in claim 1, wherein the hierarchical codebook comprises a first codebook concatenated with a second codebook.
3. A method as claimed in claim 1, wherein the hierarchical codebook includes first index corresponding to a course quantization and a second index corresponding to a fine quantization.
4. A method as claimed in claim 3, wherein the PMI comprises the first index and the second index of the hierarchical codebook.
5. A method as claimed in claim 2, wherein a value of the first codebook allows for a subset of the second codebook to be searched without requiring the entire hierarchical codebook to be searched.
6. A mobile device, comprising:
a receiver to receive a wireless signal from a transmitting device to generate precoding feedback; and
a processor to determine a precoding matrix indicator (PMI) in response to the wireless signal based at least in part on a hierarchical codebook;
wherein the receiver is configured to report the PMI back to the transmitting device.
7. A mobile device as claimed in claim 6, wherein the hierarchical codebook comprises a first codebook concatenated with a second codebook.
8. A mobile device as claimed in claim 6, wherein the hierarchical codebook includes first index corresponding to a course quantization and a second index corresponding to a fine quantization.
9. A mobile device as claimed in claim 8, wherein the PMI comprises the first index and the second index of the hierarchical codebook.
10. A mobile device as claimed in claim 7, wherein a value of the first codebook allows for a subset of the second codebook to be searched without requiring the entire hierarchical codebook to be searched.
11. A system, comprising:
a receiver to receive a wireless signal from a transmitting device to generate precoding feedback; and
an array of one or more antennas through which the receiver is capable of establishing a wireless communication channel with the transmitting device;
wherein the receiver is configured to:
determine a precoding matrix indicator (PMI) in response to the wireless signal based at least in part on a hierarchical codebook; and
report the PMI back to the transmitting device.
12. A system as claimed in claim 11, wherein the hierarchical codebook comprises a first codebook concatenated with a second codebook.
13. A system as claimed in claim 11, wherein the hierarchical codebook includes first index corresponding to a course quantization and a second index corresponding to a fine quantization.
14. A system as claimed in claim 13, wherein the PMI comprises the first index and the second index of the hierarchical codebook.
15. A system as claimed in claim 12, wherein a value of the first codebook allows for a subset of the second codebook to be searched without requiring the entire hierarchical codebook to be searched.
16. An article of manufacture comprising a non-transitory machine readable medium having instructions stored thereon that, if executed, result in:
receiving a wireless signal from a transmitting device to generate precoding feedback;
