Abstract

In order to improve continuous packet connectivity (CPC), the present invention provides a method of improving CPC for a user equipment (UE) in a wireless communications system. The method includes receiving the HS-PDSCHs indicated by a control information and decoding the data on the HS-PDSCHs according to the control information when detecting an HS-SCCH carrying the control information intended for the UE, and at the same time, receiving the HS-PDSCHs indicated by a specific control information and decoding the data on the HS-PDSCHs according to the specific control information when a specific operation is enabled.

Claims

1. A method of improving continuous packet connectivity (CPC) for a user equipment (UE) in a wireless communications system the method comprising:

receiving a first HS-PDSCHs indicated by a control information and decoding data on the first HS-PDSCHs according to the control information when detecting an HS-SCCH carrying the control information intended for the UE regardless of whether or not an HS-SCCH less operation is enabled, and when the HS-SCCH less operation is enabled, receiving at the same time a second HS-PDSCHs indicated by a specific control information and decoding data on the second HS-PDSCHs according to the specific control information.

2. The method of claim 1, wherein the specific control information is a default control information sent by a base station in the wireless communications system when the HS-SCCH less operation is enabled, for receiving the second HS-PDSCHs according to the default control information.

3. The method of claim 1, wherein the control information and the specific control information comprises radio resource and coding scheme information.

4. A communications device of a wireless communications system utilized for improving continuous packet connectivity (CPC) the communication 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 first HS-PDSCHs indicated by a control information and decoding data on the first HS-PDSCHs according to the control information when detecting an HS-SCCH carrying the control information intended for the UE regardless of whether or not an HS-SCCH less operation is enabled, and when the HS-SCCH less operation is enabled, receiving at the same time a second HS-PDSCHs indicated by a specific control information and decoding data on the second HS-PDSCHs according to the specific control information.

5. The communications device of claim 4, wherein the specific control information is a default control information sent by a base station in the wireless communications system when the HS-SCCH less operation is enabled, for receiving the second HS-PDSCHs according to the default control information.

6. The communications device of claim 4, wherein the control information and the specific control information comprises radio resource and coding scheme information.

7. The method of improving transmission efficiency for a user equipment (UE) in a wireless communications system, and the method comprising:

receiving a shared channel indicated by a control information and decoding data on the shared channel according to the control information when detecting a first control channel carrying the control information intended for the UE regardless of whether or not an HS-SCCH less operation is enabled, and when the HS-SCCH less operation is enabled, receiving at the same time the shared channel indicated by a specific control information and decoding the data on the shared channel according to the specific control information, wherein the HS-SCCH less operation comprises receiving the shared channel without monitoring a second control channel.

8. The method of claim 7, wherein the control information and the specific control information comprise radio resource and coding scheme information.

9. A communications device of a wireless communications system utilized for improving transmission efficiency, 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 shared channel indicated by a control information and decoding data on the shared channel according to the control information when detecting a first control channel carrying the control information intended for the communications device regardless of whether or not an HS-SCCH less operation is enabled, and when the HS-SCCH less operation is enabled, receiving at the same time the shared channel indicated by a specific control information and decoding the data on the shared channel according to the specific control information, wherein the HS-SCCH less operation comprises receiving the shared channel without monitoring a second control channel.

10. The communications device of claim 9, wherein the control information and the specific control information comprise radio resource and coding scheme information.
