Multiple input, multiple output wireless communication system, associated methods and data structures

A method, comprising:

• receiving a wireless communication signal;
• and
• generating a large matrix codebook 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, generating the fine codebook comprising:
• selecting a suitable small matrix codebook based at least in part on the one or more characteristics of the received wireless communication signal, the small matrix codebook comprising coarse matrix codewords and a fewer number of matrix codewords than a number of matrix codewords of the large matrix codebook;
• and
• combining the small matrix codebook with additional codewords to generate the large matrix codebook, the additional codeword comprising fine matrix codewords.

A communication device, comprising:

• a receiver responsive to a wireless communication signal received from a remote communication device, the receiver being configured to:
• generate a large matrix codebook based, at least in part, on one or more perceived characteristics of the received wireless communication signal for quantization and communication back to a source of the received signal, the receiver being further configured to:
• select a suitable small matrix codebook based at least in part on the one or more characteristics of the received signal;
• and
• combine the small codebook with one or more additional codewords to generate the large matrix codebook, the one or more additional codewords comprising fine matrix codewords.

A system, comprising:

• a receiver responsive to a wireless communication signal received from a remote communication device;
• and
• an array of one or more antennas through which the receiver is capable of establishing a wireless communication channel with a remote communication device, the receiver being configured to:
• generate a large matrix codebook based, at least in part, on one or more perceived characteristics of the received wireless communication signal for quantization and communication back to a source of the received signal, the receiver being further configured to:
• select a suitable small codebook based at least in part on the one or more characteristics of the received signal, the small matrix codebook comprising coarse matrix codewords and a fewer number of matrix codewords than a number of matrix codewords of the large matrix codebook;
• and
• combine the uniform codebook with one or more additional codewords to generate the non-uniform codebook, the one or more additional codewords comprising fine matrix codewords.

An article of manufacture comprising a non-transitory storage medium having stored thereon instructions that, if executed, result in:

• receiving a wireless communication signal;
• and
• generating a large matrix codebook 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, generating the large matrix codebook comprising:
• selecting a suitable small matrix codebook based, at least in part on the one or more characteristics of the received wireless communication signal, the small matrix codebook comprising coarse matrix codewords and a fewer number of matrix codewords than a number of matrix codewords of the large matrix codebook;
• and
• combining the small matrix codebook with additional codewords to generate the large matrix codebook, the additional codewords comprising fine matrix codewords.
