Abstract
A system and method for feeding back channel information are provided. A method for communications device operations includes generating feedback information, encoding the feedback information to produce a feedback payload, and transmitting the feedback payload to a communications server serving a communications device. The feedback information includes at least a first long term wideband channel statistics and a second long term wideband channel statistics.
Claims34
A method for communications device operations, the method comprising:
- generating feedback information, wherein the feedback information comprises at least a first long term wideband channel statistics and a second long term wideband channel statistics;
- encoding the feedback information to produce a feedback payload;
- and
- transmitting the feedback payload to a communications server serving a communications device.
A method for communications controller operations, the method comprising:
- receiving a feedback payload from a communications device;
- decoding the feedback payload with a feedback decoder to produce feedback information, wherein the feedback information comprises at least a first long term wideband channel statistics and a second long term wideband channel statistics;
- and
- precoding a transmission in accordance with the first long term wideband channel statistics and the second long term wideband channel statistics.
A communications device comprising:
- a channel estimate unit configured to be coupled to a receiver, and to estimate a communications channel between the communications device and a communications controller serving the communications device;
- a feedback information generator coupled to the channel estimate unit, the feedback information generator configured to generate feedback information in accordance with the estimate of the communications channel and to encode the feedback information to produce a feedback payload, wherein the feedback information comprises at least a first long term wideband channel statistics and a second long term wideband channel statistics;
- and
- a transmitter coupled to the feedback information generator, the transmitter configured to transmit the feedback payload to the communications controller.
