Abstract
A system and method for the quantization of channel state vectors is provided. A method for communications node operation includes measuring a communications channel between the communications node and a controller, generating channel state information based on the measurement, computing a bit representation of the channel state information, transmitting the bit representation to the controller, and receiving a transmission from the controller. The computing makes use of tail-biting trellis decoding, and the transmission makes use of the channel state information transmitted by the communications node.
Claims15
A method for communications node operation, the method comprising:
- measuring a communications channel between the communications node and a controller;
- generating channel state information based on the measurement;
- computing a bit representation of the channel state information, wherein the computing uses tail-biting trellis decoding;
- transmitting the bit representation to the controller;
- and
- receiving a transmission from the controller, wherein the transmission makes use of the channel state information transmitted by the communications node.
A method for communications node operation, wherein the communications node is served by a plurality of controllers, the method comprising:
- measuring a joint communications channel between the communications node and each controller in the plurality of controllers;
- generating channel state information based on the measurement;
- computing a bit representation of the channel state information, wherein the computing makes use of tail-biting trellis decoding;
- transmitting the bit representation to each controller in the plurality of controllers;
- and
- receiving a transmission from each controller in the plurality of controllers, wherein the transmission makes use of channel state information transmitted by the communications node.
