具有经过极化编码的传输的混合自动重传请求(HARQ)
Abstract:
对于利用极化码的通信，提供了混合自动重传请求(HARQ)算法，该算法通过根据第一传输的码率选择追赶合并HARQ(HARQ-CC)或增量冗余HARQ(HARQ-IR)来利用HARQ-CC和HARQ-IR的优点。在一些示例中，HARQ算法在第一传输中的码率大于码率门限时利用HARQ-IR，并且在第一传输中的码率小于码率门限时利用HARQ-CC。
Abstract(English):

For communication utilizing polar codes, a hybrid automatic repeat request (HARQ) algorithm is provided that takes advantage of the benefits of chase combining HARQ (HARQ-CC) and incremental redundancy HARQ (HARQ-IR), by selecting one or the other in accordance with a code rate of the first transmission. In some examples, the HARQ algorithm utilizes HARQ-IR when the code rate in the first transmission is greater than a code rate threshold, and utilizes HARQ-CC when the code rate in the first transmission is less than the code rate threshold.
