UL control channel consideration for heterogeneous networks |
| 摘要 |
A method in a network node comprises providing to a user equipment a dedicated physical control channel (DPCCH), the DPCCH having an associated first fractional dedicated physical channel (F-DPCH) for conveying transmit power control commands to the user equipment for power controlling the DPCCH, and providing to the user equipment a secondary dedicated physical control channel (S-DPCCH), the S-DPCCH comprising an uplink control channel for communicating transmit power control commands, the S-DPCCH having an associated second F-DPCH for conveying transmit power control commands to the user equipment for power controlling the S-DPCCH. The method comprises receiving, from the user equipment, a downlink transmit power control command, the downlink transmit power control command carried on the S-DPCCH; and controlling a transmit power of the second F-DPCH associated with the S-DPCCH based on the downlink transmit power control command carried on the S-DPCCH. |

1. A method in a network node, comprising:
providing to a user equipment a dedicated physical control channel (DPCCH), the DPCCH having an associated first fractional dedicated physical channel (F-DPCH) for conveying transmit power control commands to the user equipment for power controlling the DPCCH; providing to the user equipment a secondary dedicated physical control channel (S-DPCCH), the S-DPCCH comprising an uplink control channel for communicating transmit power control commands, the S-DPCCH having an associated second F-DPCH for conveying transmit power control commands to the user equipment for power controlling the S-DPCCH; receiving, from the user equipment, a downlink transmit power control command, the downlink transmit power control command carried on the S-DPCCH and determined based at least in part on a quality of the second F-DPCH independent of a quality of a third F-DPCH associated with a second network node; and controlling a transmit power of the first F-DPCH associated with the DPCCH and the second F-DPCH associated with the S-DPCCH based on the downlink transmit power control command carried on the S-DPCCH. |
