Abstract
In a particular embodiment, a method of providing redundancy for error recovery in multi-carrier wireless communications includes transmitting a primary version of information via a first carrier, transmitting a first portion of a redundancy version of the information via a second carrier, and transmitting a second portion of the redundancy version of the information via a third carrier. The primary version is encoded using a first encoding scheme and the redundancy version is encoded using a second encoding scheme. The primary version, the first portion, and the second portion are transmitted substantially simultaneously.
