The electronic apparatus includes: a first communication module configured to communicate in a first communication method, and a second communication module configured to communicate in a second communication method. The first communication module is further configured to change a transmission output level of the first communication module from a first transmission output level to a second transmission output level in response to the second communication module receiving data, and change the transmission output level from the second transmission output level to the first transmission output level in response to the second communication module completing the reception of the data.

An apparatus according to an aspect of the present disclosure includes a communication module that includes a transmitter that carries out an uplink transmission of an uplink shared channel (physical uplink shared channel (PUSCH)), and a processor that controls a transmission power used in the uplink transmission based on: a value that is calculated based on a number of resource blocks of the uplink transmission and one of a plurality of numerologies having different subcarrier spacings, and a transmission power command (TPC) included in a downlink control information (DCI) format, wherein information about the one of the plurality of numerologies is received via higher layer signaling; and an input apparatus that accepts an input, wherein the PUSCH contains information based on the input. In another aspect, a system is also disclosed.

A method of wireless communication includes receiving, by a network device from a server, first data associated with an application. The method further includes, during a first monitoring occasion associated with the application, transmitting, by the network device, the first data to a first group of multiple user equipment (UE) devices that execute the application. The method further includes transmitting a message to the first group after transmitting the first data. The message indicates completion of the first monitoring occasion.
