Abstract

In one embodiment, a method includes receiving a first indicator of channel quality between a user equipment (UE) and a first network node and receiving a second indicator of channel quality between the UE and a second network node. The method also includes processing the first indicator of channel quality and processing the second indicator of channel quality.

Claims

1. A method comprising:

receiving a first indicator of channel quality between a user equipment (UE) and a first network node;

receiving a second indicator of channel quality between the UE and a second network node;

processing the first indicator of channel quality; and

processing the second indicator of channel quality.

2. The method of claim 1, further comprising determining a transmission condition in accordance with the first and second indicator of channel quality.

3. The method of claim 2, wherein the transmission condition is a restricted resource subframe condition.

4. The method of claim 2, further comprising receiving, by the first network node from a radio network controller (RNC), the transmission condition.

5. The method of claim 2, further comprising transmitting, by the first network node to an RNC, the transmission condition, wherein the transmission condition is destined for the second network node.

6. The method of claim 2, wherein the transmission condition is selected from the group consisting of a transport block size condition, a channel quality condition, a code number condition, and a modulation condition.

7. The method of claim 1, wherein the first network node is a serving node and the second network node is a non-serving node.

8. The method of claim 7, wherein the non-serving node is included in an active set of the UE.

9. The method of claim 7, wherein the non-serving node is not included in an active set of the UE.

10. The method of claim 1, further comprising scheduling a transport block in accordance with the first indicator of channel quality and the second indicator of channel quality.

11. The method of claim 10, further comprising transmitting, by the first network node to the UE, the scheduled transport block.

12. The method of claim 1, wherein the processing further comprises sending the first and second indicator of channel quality to a third network node.

13. A method comprising:

transmitting, by a radio network controller (RNC) to a serving node, a transmission pattern;

transmitting, by the RNC to a non-serving node, the transmission pattern;

receiving, by the RNC, a measurement report indicating a quality of a first channel between a user equipment (UE) and the serving node and a quality of a second channel between the UE and the non-serving node; and

determining a transmission condition in accordance with the measurement report.

14. The method of claim 13, further comprising transmitting, by the RNC to the non-serving node, the transmission condition.

15. The method of claim 13, wherein the measurement report comprises a first common pilot channel (CPICH) energy per chip (Ec) on spectral density (No) of the first channel and a second CPICH Ec/No of the second channel.

16. The method of claim 13, wherein transmitting, by the RNC to the serving node, the transmission pattern comprises transmitting the transmission pattern on Iub signaling.

17. A method comprising:

determining a first indicator of channel quality between a user equipment (UE) and a serving node;

determining a second indicator of channel quality between the UE and a first non-serving node;

transmitting the first indicator of channel quality; and

transmitting the second indicator of channel quality.

18. The method of claim 17, wherein transmitting the first indicator of channel quality comprises encoding the first indicator of channel quality with high speed dedicated physical control channel (HS-DPCCH), and wherein transmitting the second indicator of channel quality comprises encoding the second indicator of channel quality with HS-DPCCH.

19. The method of claim 18, wherein encoding the first indicator of channel quality comprises encoding the first indicator of channel quality in universal mobile telecommunications service (UMTS) single frequency dual cell (SF-DC) mode or multiple-input multiple-output (MIMO) mode.

20. The method of claim 17, further comprising:

transmitting, by the UE to a radio network controller (RNC), the first indicator of channel quality; and

transmitting, by the UE to the RNC, the second indicator of channel quality.

21. The method of claim 17, further comprising:

determining a third indicator of channel quality between the UE and a second non-serving node; and

transmitting the third indicator of channel quality.

22. A method comprising:

receiving, by a radio network controller (RNC) from a user equipment (UE), a first indicator of channel quality;

receiving, by the RNC from the UE, a second indicator of channel quality;

processing the first indicator of channel quality; and

processing the second indicator of channel quality.

23. The method of claim 22, further comprising:

determining a transmission condition in accordance with the first indicator of channel quality and the second indicator of channel quality; and

transmitting, by the RNC to a first network node, the transmission condition.

24. The method of claim 23, further comprising transmitting, by the RNC to a plurality of network nodes, the transmission condition.

25. A first network node comprising:

a processor; and

a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to

receive a first indicator of channel quality between a first user equipment (UE), and the first network node,

receive a second indicator of channel quality between the UE and a second network node,

process the first indicator of channel quality, and

process the second indicator of channel quality.
