摘要
一種用於減少混和式自動重傳操作所需記憶體空間的方法及裝置。當執行該方法的裝置接收到以低密度同位元檢查碼(Low Density Parity Check Code，LDPC)編碼的封包時，該裝置首先估算已接收封包的訊號品質值，並對已接收封包執行LDPC解碼演算法。如果該裝置沒有成功地對已接收封包進行解碼，則對解碼失敗的已接收封包進行壓縮，並將壓縮後的已接收封包存儲在記憶體中，以用於接下來的混合式自動重傳操作。
A method reducing amount of memory utilized by hybrid automatic repeat request (HARQ) operations is disclosed. When an apparatus employing the method receives an LDPC encoded packet, the apparatus firstly estimates a signal quality value of the received packet, and performs an LDPC decoding algorithm on the received packet. If the received packet is not successfully decoded by the apparatus, the received and decoding-failed packet is compressed in order to reduce bit-width, and the compressed packet is stored in a memory device for later HARQ operations. The apparatus employing the method is also disclosed.
