1. A method of providing redundancy for error recovery in multi-carrier wireless communications, the method comprising:

  • selecting a transmission strategy at least partially based on a data reception condition indication of a transmission, the data reception condition indication received from a mobile device;

    encoding a primary version of information to be transmitted with a first encoding scheme;

    encoding a redundancy version of the information to be transmitted with a second encoding scheme;

    transmitting the primary version of the information encoded with the first encoding scheme, the primary version being transmitted on a first carrier; and

    transmitting the redundancy version of the information encoded with the second encoding scheme, at least part of the redundancy version being transmitted on a second carrier;

    wherein encoding and transmitting the primary version and the redundancy version are performed in accordance with the selected transmission strategy and wherein selecting the transmission strategy includes determining whether the first carrier has a first frequency that is prone to fading and in response to determining that the first frequency is prone to fading, selecting the second carrier to have a second frequency that is different from the first frequency and selecting the second encoding scheme to match the first encoding scheme.
