Abstract
Effective management of a Hybrid-Automatic Repeat reQuest (HARQ) buffer in a wireless communication system is provided. A receiving terminal includes a first memory for storing Log Likelihood Ratio (LLR) values of at least one data block comprised in a received HARQ burst in a first memory, a channel decoder for decoding the at least one data block by using the LLR values, an error detection unit for detecting whether there are errors in the decoded at least one data block, and a second memory for storing at least one error-free data block in a decoded state among the data blocks in a second memory.
Claims24
An operation method of a receiving terminal in a wireless communication system, the method comprising:
- storing Log Likelihood Ratio (LLR) values of at least one data block comprised in a received Hybrid Automatic Repeat reQuest (HARQ) burst in a first memory;
- decoding the at least one data block by using the LLR values;
- and
- storing at least one error-free data block in a decoded state in a second memory.
An apparatus of a receiving terminal in a wireless communication system, the apparatus comprising:
- a first memory configured to store Log Likelihood Ratio (LLR) values of at least one data block comprised in a received Hybrid Automatic Repeat reQuest (HARQ) burst in a first memory;
- a decoder configured to decode the at least one data block by using the LLR values;
- and
- a second memory configured to store at least one error-free data block in a decoded state in a second memory.
