Abstract
Embodiments of methods and apparatus for providing aggregated feedback from a subscriber station to a base station are generally described herein. Some embodiments may include a channel response predictor to predict channel responses for future feedback periods and a feedback information generator to aggregate feedback information, generated based on the predicted channel responses, into an aggregated information block that is to be transmitted to a base station. Other embodiments may be described and claimed.
Claims21
An apparatus comprising:
- a channel response predictor to predict for a subscriber station hosting the apparatus, a plurality of channel responses for a first plurality of points in time corresponding to a plurality of future feedback periods for the subscriber station to provide feedback to a base station;
- and
- a feedback information generator coupled to the channel response predictor to receive the predicted channel responses, to generate feedback information for each of the plurality of future feedback periods based on the predicted channel responses, to aggregate the feedback information for each of the plurality of future feedback periods into an aggregated information block, and to code the aggregated information block into a single transmission block to be transmitted, to the base station, in an uplink data channel.
An article of manufacture comprising:
- a storage medium;
- and
- a plurality of programming instructions stored therein, and configured to program a communication module of a subscriber station to enable the communication module
- to predict for the subscriber station a plurality of channel responses for a first plurality of points in time corresponding to a plurality of future feedback periods for the subscriber station to provide feedback to a base station;
- to generate for the subscriber station feedback information for each of the plurality of future feedback periods based on the predicted channel responses;
- to aggregate the feedback information for each of the plurality of future feedback periods into an aggregated information block;
- and
- to code the aggregated information block into a single transmission block to be transmitted to the base station in an uplink data channel.
5 more elements
A method comprising:
- receiving by a base station a single transmission block over an uplink data channel, the single transmission block including aggregated feedback information from a subscriber station, the aggregated feedback information comprising feedback information for a plurality of future feedback periods;
- recovering by the base station, the feedback information;
- and
- transmitting a downlink transmission to the subscriber station based on the feedback information.
1 more element
A system comprising:
- a plurality of antennas;
- a memory;
- a processor coupled to the memory;
- and
- a communication module coupled to the processor and the plurality of antennas, configured
- to predict for the system a plurality of channel responses for a first plurality of points in time corresponding to a plurality of future feedback periods for the system to provide feedback to a base station;
- and
- to generate feedback information for each of the plurality of future feedback periods based on the predicted channel responses, to aggregate the feedback information for each of the plurality of future feedback periods into an aggregated information block, and to code the aggregated information block into a single transmission block to be transmitted, to the base station, in an uplink data channel over the plurality of antennas.
