Abstract
A method and apparatus optimize antenna precoder selection with coupled antennas. A power metric corresponding to each precoder of a plurality of precoders can be received at a receiving device. Reference signals can be received. A transmission channel corresponding to each precoder can be estimated based on the reference signals. The estimate of the transmission channel can be scaled based on the power metric for each precoder. A channel quality metric for each precoder can be generated based on the scaled estimate of the transmission channel. An index of a precoder with the largest channel quality metric can be transmitted.

A method comprising:
- receiving a power metric corresponding to each precoder of a plurality of precoders;
- receiving reference signals;
- estimating a transmission channel corresponding to each precoder based on the reference signals;
- scaling the estimate of the transmission channel based on the power metric for each precoder;
- generating a channel quality metric for each precoder based on the scaled estimate of the transmission channel;
- and
- transmitting an index of a precoder with the largest channel quality metric.
An apparatus comprising:
- a transceiver to receive a power metric corresponding to each precoder of a plurality of precoders and to receive reference signals;
- and
- a controller coupled to the transceiver, the controller to
- estimate a transmission channel corresponding to each precoder based on the reference signals,
- scale the estimate of the transmission channel based on the power metric for each precoder, and
- generate a channel quality metric for each precoder based on the scaled estimate of the transmission channel,
- wherein the transceiver transmits an index of a precoder with the largest channel quality metric.
A method comprising:
