RHMT (Reordered HARQ Mini-Tile)

However, I can provide you with a general overview of HARQ (Hybrid Automatic Repeat Request), which is a widely used error control mechanism in wireless communication systems. HARQ is employed to improve the reliability of data transmission by allowing the receiver to request retransmission of erroneous packets.

HARQ operates in two major modes: Chase Combining (CC) and Incremental Redundancy (IR). In CC, the retransmitted packet contains the entire data, while in IR, only the missing information (parity bits) is sent. The receiver combines the original and retransmitted packets to improve the overall reception quality.

Reordering refers to the rearrangement of received data packets at the receiver side to optimize the decoding process. By rearranging the packets in a specific order, the receiver can improve the chances of successful decoding and minimize the effect of errors. This is particularly useful in scenarios where packets arrive out of order due to various factors like network congestion, packet loss, or transmission delays.
