The present disclosure provides a method and a system for managing the power of a radio unit (RU) (130) of a next generation NodeB (gNB) (100) operating in a wireless communication network. The RU comprising a plurality of transmitter and receiver (TRX) radio modules (134) for data processing. The method comprises determining a plurality of user equipment's (UE's) (150) serving a cell associated with said gNB, The method further includes periodically changing power of at least one TRX radio module from said plurality of TRX modules based on the determined plurality of UE's serving said cell associated with said gNB, where said the power of said at least one TRX radio module is periodically changed without shutting down said RU.

Provided is a terminal which can suitably transmit an uplink signal. In a terminal (100), a PC parameter control unit (104) sets a first power control parameter corresponding to a first service, when a prescribed condition relating to a control channel used for transmission of uplink signal allocation is met, and sets a second power control parameter corresponding to a second service, when the prescribed condition is not met. A transmission unit (109) transmits the uplink signal by using transmission power calculated by using the first power control parameter or the second power control parameter.

Embodiments of the present disclosure provide a method for transmitting uplink control information. The method includes: a User Equipment (UE) receives Uplink Control Information UCI configuration information, wherein the UCI configuration information includes information for determining a periodicity, an offset and a Physical Uplink Control Channel PUCCH for Periodic-Channel State Information P-CSI to be report in one subframe and configuration information for transmission of Hybrid Automatic Retransmission reQuest-Acknowledgement HARQ-ACK; processes one or more kinds of UCI in the subframe, and transmits the on resources using a PUCCH format. According to the method of the present disclosure, the transmit power for transmitting the UCI on the channel using the PUCCH format is optimized. During the transmission of the P-CSI, the PUCCH resource most preferable for the transmission of the P-CSI is determined. The uplink resource utilization ratio is increased.
