Method and apparatus for power saving in wireless communication system

A method performed by a terminal in a wireless communication system, the method comprising:

• receiving, from a base station, configuration information on a cell discontinuous reception (DRX) and a cell discontinuous transmission (DTX);
• identifying an overlapping of uplink (UL) transmissions, wherein the UL transmissions include at least two transmissions among physical uplink control channel (PUCCH) transmissions or physical uplink shared channel (PUSCH) transmissions;
• and
• identifying whether to perform a UL transmission after resolving the overlapping of the UL transmissions, in case that the cell DRX is activated for a serving cell and the UL transmission overlaps with a non-active period of the cell DRX.

A terminal comprising:

• at least one transceiver;
• at least one processor communicatively coupled to the at least one transceiver;
• and
• at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the terminal to:
• receive, from a base station, configuration information on a cell discontinuous reception (DRX) and a cell discontinuous transmission (DTX),
• identify an overlapping of uplink (UL) transmissions, wherein the UL transmissions include at least two transmissions among physical uplink control channel (PUCCH) transmissions or physical uplink shared channel (PUSCH) transmissions, and
• identify whether to perform a UL transmission after resolving the overlapping of the UL transmissions, in case that the cell DRX is activated for a serving cell and the UL transmission overlaps with a non-active period of the cell DRX.

A base station comprising:

• at least one transceiver;
• at least one processor communicatively coupled to the at least one transceiver;
• and
• at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the base station to:
• transmit, to a terminal, configuration information on a cell discontinuous reception (DRX) and a cell discontinuous transmission (DTX),
• wherein an uplink (UL) reception is performed after an overlapping of UL receptions is resolved, in case that the cell DRX is activated for a serving cell and the UL reception overlaps with a non-active period of the cell DRX,
• wherein the UL receptions include at least two receptions among physical uplink control channel (PUCCH) receptions or physical uplink shared channel (PUSCH) receptions.
