    Abstract: Multiple power management integrated circuits (PMICs) may perform communication and power sequence operation coordination between the multiple PMICs through a communication interface connected to two signal lines using a dual pin interface. The multiple PMICs include a main PMIC configured to communicate with at least one application processor through a system interface and at least one sub-PMIC configured to communicate with the main PMIC through the communication interface. A first signal line uses a single bidirectional signaling scheme, and a power status signal PSTATUS is exchanged between the main PMIC and the at least one sub-PMIC through the first signal line. A second signal line uses a single unidirectional signaling scheme, and a power sequence control signal PIF is transmitted from the main PMIC to the at least one sub-PMIC through the second signal line.

    Abstract: The disclosure relates to a method for operating a base station in a wireless communication system, and discloses a method and apparatus which: receive periodic uplink control information (UCI) from a terminal in a connected discontinuous reception (C-DRX) on state; predict reception power of a scheduling request (SR) message based on reception power of the periodic UCI; based on a base station receiving, in a C-DRX off state, the SR message from the terminal, measure the reception power of the SR message; based on the measured reception power of the SR message and the predicted reception power of the SR message, set a maximum number of retransmissions of an UL grant that may be transmitted by the base station; retransmit the UL grant by the base station in response to the received SR message; and based on identifying that the number of retransmissions of the UL grant reaching the maximum number of retransmissions of the UL grant, determine that the base station does not receive the SR message.
