ACCURATE UPLINK POWER CONTROL FOR COMP AND C-RAN |
| 摘要 |
A user equipment (UE) is arranged to send an uplink power reference signal to an enhanced Node B (eNB) associated with multiple reception points (RPs), to receive identification of an RP set and a downlink reference signal power level, to determine a path loss estimate for each downlink reference signal received from RPs of the RP set, to determine an uplink power level that is a function of the path loss estimates determined for the downlink signals received from the RPs of the RP set, and to use the determined uplink power level during communication with the multiple RPs. |

1. A user equipment (UE) arranged to communicate with an enhanced Node B (eNB) that includes multiple reception points (RPs), the UE arranged to, send an uplink power reference signal to the eNB associated with multiple reception points (RPs);
receive identification of a set of RPs and identification of a downlink reference signal power level to be used by RPs of the identified set; receive downlink reference signals from RPs of the identified set; determine a path loss estimate for each received downlink reference signals; determine an uplink power level that is a function of the path loss estimates determined for the downlink signals received from the RPs of the identified set; and use the determined uplink power level during communication with the multiple RPs. |
