Method and apparatus for optimizing target error rates for link adaptation in a communication system

摘要

A method and apparatus for optimizing target error rates for link adaptation in a communication system. The method includes estimating a data rate associated with transmission of a data stream over a communication link. A required target error rate is then selected from a plurality of pre-defined target error rate values based on whether the estimated data rate is within a range of at least one of a plurality of pre-defined threshold values, where each of the pre-defined target error rate values maps to one of the plurality of pre-defined threshold values. A link adaptation parameter associated with the communication link is then selected or updated to maintain the required target error rate and the data stream is transmitted over the communication link using the selected/updated link adaptation parameter.

1. A method comprising:
estimating a data rate associated with transmission of a data stream over a communication link according to a pre-defined communication protocol; selecting a required target error rate from a plurality of pre-defined target error rate values based on whether the estimated data rate is within a range of at least one of a plurality of pre-defined data rate threshold values, wherein each of the pre-defined target error rate values is mapped to one of the plurality of pre-defined data rate threshold values, and wherein the pre-defined data rate threshold values are selected, and the plurality of pre-defined target error rate values are mapped to the pre-defined data rate threshold values, such that the selected target error rate is higher than a target error rate which the communication protocol specifies for the estimated data rate; updating a link adaptation parameter associated with the communication link to maintain the required target error rate; and transmitting the data stream over the communication link using the updated link adaptation parameter.
