Abstract
In accordance with one or more embodiments of the present disclosure a method for generating a codebook comprises generating a plurality of wireless communication channel representations. The method further comprises generating a precoding matrix for each of the plurality of wireless communication channel representations. The method additionally comprises performing a clustering operation on the precoding matrices to determine a plurality of centroids associated with the precoding matrices. Also the method includes determining codewords based on the centroids and generating a codebook based on the codewords.
Claims18
A method for generating a codebook comprising:
- using a processor, generating a plurality of wireless communication channel representations, wherein generating the plurality of wireless communication channel representations comprises:
- determining a first wireless communication channel representation associated with downlink (DL) communication between a first transmission site and an endpoint;
- determining a second wireless communication channel representation associated with DL communication between a second transmission site and the endpoint;
- and
- combining the first wireless communication channel representation with the second wireless communication channel representation to form a composite wireless communication channel representation associated with a joint DL communication between the endpoint and the first transmission site and the second transmission site;
- using the processor, generating a precoding matrix for each of the plurality of wireless communication channel representations;
- using the processor, performing a clustering operation on the precoding matrices to determine a plurality of centroids associated with the precoding matrices;
- using the processor, determining codewords based on the centroids;
- using the processor, generating a codebook based on the codewords;
- and
- transmitting the codebook to at least one of the first transmission site and the second transmission site for use in communications with the endpoint.
One or more non-transitory computer-readable media embodying logic that, when executed by a processor, is configured to perform operations comprising:
- generating a plurality of wireless communication channel representations, wherein generating the plurality of wireless communication channel representations comprises:
- determining a first wireless communication channel representation associated with downlink (DL) communication between a first transmission site and an endpoint;
- determining a second wireless communication channel representation associated with DL communication between a second transmission site and the endpoint;
- and
- combining the first wireless communication channel representation with the second wireless communication channel representation to form a composite wireless communication channel representation associated with a joint DL communication between the endpoint and the first transmission site and the second transmission site;
- generating a precoding matrix for each of the plurality of wireless communication channel representations;
- performing a clustering operation on the precoding matrices to determine a plurality of centroids associated with the precoding matrices;
- determining codewords based on the centroids;
- generating a codebook based on the codewords;
- and
- transmitting the codebook to at least one of the first transmission site and the second transmission site for use in communications with the endpoint.
