Abstract
A method of improving Hybrid Automatic Repeat Request operation for a user equipment operating in HS-SCCH less operation in a wireless communications system includes receiving a retransmission data in an HARQ procedure, determining a decoding result of data stored in a first soft buffer, combining the retransmission data with the data stored in the first soft buffer for generating a combined data when the UE determines that the data stored in the first soft buffer has not been successfully decoded, and performing a decoding process on the combined data and a store process corresponding to a second soft buffer. The first soft buffer is obtained by a first rule and the second soft buffer is obtained by a second rule.

A method of improving Hybrid Automatic Repeat Request, abbreviated to HARQ, operation for a user equipment, called UE hereinafter, operating in HS-SCCH less operation in a wireless communications system, the method comprising:
- receiving a retransmission data in an HARQ procedure;
- determining a decoding result of data stored in a first soft buffer;
- combining the retransmission data with the data stored in the first soft buffer for generating a combined data when the UE determines that the data stored in the first soft buffer has not been successfully decoded;
- and
- performing a decoding process on the combined data and a store process corresponding to a second soft buffer;
- wherein the first soft buffer is obtained by a first rule and the second soft buffer is obtained by a second rule.
A communications device operating in HS-SCCH less operation of a wireless communications system for improving Hybrid Automatic Repeat Request, abbreviated to HARQ, operation, the communications device comprising:
- a control circuit for realizing functions of the communications device;
- a central processing unit installed in the control circuit for executing a program code to operate the control circuit;
- and
- a memory coupled to the central processing unit for storing the program code;
- wherein the program code comprises:
- receiving a retransmission data in an HARQ procedure;
- determining a decoding result of data stored in a first soft buffer;
- combining the retransmission data with the data stored in the first soft buffer for generating a combined data when the communications device determines that the data stored in the first soft buffer has not been successfully decoded;
- and
- performing a decoding process on the combined data and a store process corresponding to a second soft buffer;
- wherein the first soft buffer is obtained by a first rule and the second soft buffer is obtained by a second rule.
