Transmit power control for DMRS bundling for coverage enhancement

A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a user equipment (UE) configured for operation in a fifth-generation new radio (5G N R) network, wherein the processing circuitry is configured to:

• decode one or more DCI formats, the one or more DCI formats including two transmit power control (TPC) commands, each TPC command associated with different power control parameters;
• determine one or more nominal time-domain windows (TDWs) for demodulation reference signals (DMRS) bundling for physical uplink control channel (PUCCH) transmissions of a PUCCH repetition;
• determine a start of a new actual TDW for DMRS bunding in response to an event which causes power consistency and phase continuity not to be maintained across the PUCCH transmissions of the PUCCH repetition, the new actual TDW to start after the event;
• and
• configure the UE to maintain power consistency and phase continuity within the new actual TDW across PUCCH transmissions of the PUCCH repetition,
• wherein the event comprises a use of the different power control parameters for two of the PUCCH transmissions of the PUCCH repetition within one of the nominal TDWs, and
• wherein when the UE is configured for TPC accumulation, the processing circuitry is to configure the UE to accumulate TPC commands during the PUCCH transmissions of the PUCCH repetition,
• wherein when the UE is a reduced capability UE configured for half-duplex frequency-division duplex (HD-FDD) operation, the event further comprises an overlapping of a gap between two consecutive of the PUCCH transmissions and any symbol of a downlink reception.
