Abstract:
1. A method in a User Equipment (UE), comprising the steps of: using a processor, receiving a power control signal from a mobile communication node to control transmit power of a Physical Uplink Control Channel (PUCCH) signal, wherein the PUCCH signal includes exactly three Hybrid Automatic Repeat Request (HARQ) bits; wherein the power control signal provides an offset value in a power control function affecting the transmit power of the PUCCH signal, and wherein the offset value compensates for an operating signal-to-noise ratio (SNR) improvement that occurs when the mobile communication node increases a Discontinuous Transmission (DTX) detection threshold when the PUCCH signal includes exactly three HARQ bits; in response to the power control signal, lowering the transmit power of the PUCCH signal by the offset value by applying the offset value-containing power control function to the PUCCH signal using the processor; and using the processor, transmitting the PUCCH signal with lower transmit power.
