BALANCING CAPACITY BETWEEN LINK DIRECTIONS USING VARIABLE FEEDBACK RATES

摘要

A method for communication includes providing a first transceiver (26, 28) configured to communicate with a second transceiver (22) over a bi-directional link having a first aggregation of frequencies that are assigned to carry first communication traffic (34) in a first link direction from the first transceiver to the second transceiver and a second aggregation of frequencies that are assigned to carry second communication traffic (36) in a second link direction from the second transceiver to the first transceiver. Communication feedback (35) is transmitted from the first transceiver to the second transceiver at an adaptive feedback rate. The feedback rate is determined so as to achieve a desired balance between the information carrying capacities of the first and second aggregations. An information carrying capacity of the second aggregation is controlled responsively to the communication feedback.
