  • Selectively controlling transmit power from a radio access network (RAN) cell to user equipment (UE) in closed-loop power control for uplink control channel based on variation in measured uplink signal quality
    Patent number: 10912030
    Abstract: Selectively controlling transmit power from a radio access network (RAN) cell to user equipment (UE) in closed-loop power control for uplink control channel based on variation in measured uplink signal quality. To avoid the RAN cell continuously sending transmit power control messages that may not be effective in further adjusting transmit power of the UE, the RAN cell selectively controls transmit power of the UE based on effectiveness in such transmit power control changing uplink channel signal quality. The determined effectiveness of the transmit power control can be used by the RAN cell to determine when the next transmit power control message should be sent to the UE. The RAN cell can be configured to indirectly measure the uplink channel power by reviewing the received uplink channel quality in a report communicated from the UE to the RAN cell.
