LINK ADAPTATION IN MULTI-CARRIER COMMUNICATION SYSTEMS
First Claim
1. A method for transmitting information in a multi-carrier system, the method comprising:
- identifying a first set of carrier signals, each carrier signal in the first set of carrier signals associated with a first code rate;
identifying a second set of carrier signals, each carrier signal in the second set of carrier signals associated with a second code rate, the second code rate different from the first code rate;
partitioning a first sequence of bits representing a single symbol into a first group of bits associated with the first code rate and at least a second group of bits associated with the second code rate;
interleaving a subset of bits from the first group of bits to map multiple bits from the first group of bits to respective carrier signals in the first set of carrier signals to achieve the first code rate on an average over the first set of carrier signals;
interleaving a subset of bits from the second group of bits to map multiple bits from the second group of bits to respective carrier signals in the second set of carrier signals to achieve the second code rate on an average over the second set of carrier signals;
modulating one or more of the carrier signals in the first set of carrier signals using the mapped bits from the first group; and
modulating one or more of the carrier signals in the second set of carrier signals using the mapped bits from the second group.

Abstract
A method for transmitting information in a multi-carrier system includes: identifying a first set of carrier signals, associated with a first code rate; and identifying a second set of carrier signals, associated with a second code rate. The method also includes partitioning a first sequence of bits representing a single symbol into a first group of bits associated with the first code rate and at least a second group of bits associated with the second code rate; interleaving a subset of bits from the first group to map multiple bits from the first group to respective carrier signals in the first set of carrier signals to achieve the first code rate; and interleaving a subset of bits from the second group to map multiple bits from the second group to respective carrier signals in the second set of carrier signals to achieve the second code rate.
