Patent ID: 8583976

Claim:
A method for hierarchy management for a hybrid automatic repeat request (HARQ) memory, comprising the following steps of: the HARQ memory comprising an on-chip memory, and the on-chip memory comprising one or more storage blocks, each of which corresponds to a using status bit for indicating whether the storage block is overlayable; when receiving new data of a coded block, searching the on-chip memory for any overlayable storage block, and if there exists an overlayable storage block, storing the new data of the coded block into the storage block and setting the using status bit corresponding to the storage block to be un-overlayable; if there is no overlayable storage block, storing the new data of the coded block into an off-chip memory; and when the new data of the coded block are checked and pass the check, setting the using status bit corresponding to the storage block in which the new data of the coded block are stored to be overlayable; and the method further comprising: storing a piece of check status identification information corresponding to each coded block, the check status identification information indicating whether the coded block passes the check; and prior to performing combination processing on the coded block when receiving resent data of the coded block, obtaining the check status identification information corresponding to the coded block, and skipping the coded block when the check status identification information indicates that the coded block passes the check; when the check status identification information indicates that the coded block does not pass the check, performing the combination processing on the coded block.
