In this paper, a new rateless scheme based on the extendibility of systematic polar codes is proposed, which is applicable for the scenario without channel state information (CSI). With detailed analyses on the existing rateless schemes, we obtain the drawbacks and difficulties which can make the schemes dysfunctional. We expound the extendibility of systematic polar codes elaborately, which forms the basis of the new rateless scheme. In addition, with the incremental redundancy hybrid automatic repeat request transmission, the new rateless scheme is established. The construction of polar codes specialized for the new scheme is also proposed, which can provide reliable performance. Comparing with the existing rateless schemes, the new scheme can be applied for arbitrary channels efficiently and reliably.
