Abstract

A method is provided for adjusting timing of transmissions within a wireless communications system. The method comprises receiving a request for a timing adjustment and adjusting timing of a DPCH in a first frame. The timing of at least one of an E-RGCH and an E-HICH is then adjusted in a second frame associated with the first frame.

Claims

1. A method for adjusting the timing of transmissions within a wireless communications system, comprising:

receiving a request for a timing adjustment;

adjusting timing of a first downlink channel in a first frame; and

adjusting timing of a second downlink channel in a second frame associated with the first frame.

2. A method, as set forth in claim 1, wherein adjusting timing of the first downlink channel in the first frame further comprises adjusting the timing of a DPCH.

3. A method, as set forth in claim 2, wherein adjusting timing of the second downlink channel in the second frame associated with the first frame further comprises adjusting timing of at least one of an E-RGCH and an E-HICH in the second frame associated with the first frame.

4. A method, as set forth in claim 3, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and wherein adjusting timing of the E-HICH in the second frame associated with the first frame further comprises adjusting timing of the E-HICH in a frame associated with SFNi-3.

5. A method, as set forth in claim 3, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and wherein adjusting timing of the E-RGCH in the second frame associated with the first frame further comprises adjusting timing of the E-RGCH in a frame associated with SFNi.

6. A method, as set forth in claim 1, wherein adjusting timing of the second downlink channel further comprises adjusting the timing of the second downlink channel in steps of 30 symbols.

7. A method, as set forth in claim 3, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and subframe 0 and wherein adjusting timing of the E-HICH in the second frame associated with the first frame further comprises adjusting timing of the E-HICH in a frame associated with SFNi in subframe 0.

8. A method, as set forth in claim 3, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and subframe 0 and wherein adjusting timing of the E-RGCH in the second frame associated with the first frame further comprises adjusting timing of the E-RGCH in a frame associated with SFNi in subframe 0.

9. A method, as set forth in claim 1, wherein adjusting timing of the second downlink channel further comprises adjusting the timing of the second downlink channel in steps of subframes.

10. A method for adjusting the timing of transmissions within a wireless communications system, comprising:

receiving a request for a timing adjustment;

adjusting timing of a DPCH in a first frame; and

adjusting timing of at least one of an E-RGCH and an E-HICH in a second frame associated with the first frame.

11. A method, as set forth in claim 10, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and wherein adjusting timing of the E-HICH in the second frame associated with the first frame further comprises adjusting timing of the E-HICH in a frame associated with SFNi-3.

12. A method, as set forth in claim 10, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and wherein adjusting timing of the E-RGCH in the second frame associated with the first frame further comprises adjusting timing of the E-RGCH in a frame associated with SFNi.

13. A method, as set forth in claim 10, wherein adjusting timing of at least one of the E-RGCH and the E-HICH further comprises adjusting the timing of at least one of the E-RGCH and the E-HICH in steps of 30 symbols.

14. A method, as set forth in claim 10, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and subframe 0 and wherein adjusting timing of the E-HICH in the second frame associated with the first frame further comprises adjusting timing of the E-HICH in a frame associated with SFNi in subframe 0.

15. A method, as set forth in claim 10, wherein adjusting the timing of the DPCH further comprises adjusting the timing of the DPCH in a frame associated with SFNi and subframe 0 and wherein adjusting timing of the E-RGCH in the second frame associated with the first frame further comprises adjusting timing of the E-RGCH in a frame associated with SFNi in subframe 0.

16. A method, as set forth in claim 10, wherein adjusting at least one of the E-RGCH and the E-HICH further comprises adjusting the timing of at least one of the E-RGCH and the E-HICH in steps of subframes.
