1. A method in a wireless communication device to eliminate data collisions wherein transmissions are made in an uncoordinated frequency hopping scheme such that the downlink channels and uplink channels are assigned in pairs, and wherein the uplink channel assignment follows the downlink assignment and uplink channel collisions occur following downlink channel collisions, said method comprising:

  • determining that a downlink channel collision has occurred including determining that a downlink data set received by the device was not intended to be received by the device;

    refraining from transmitting an uplink data set during the scheduled uplink period; and

    transmitting the uplink data set on the next scheduled uplink period thereby avoiding an uplink channel collision.
