Abstract: Methods, systems, and devices for power control in New Radio (NR) systems are described. In one example, a user equipment (UE) may determine a transmit power for a control channel based on an effective code rate of control information to be transmitted in the control channel. In another example, the UE may be configured to use a different transmit power for repeated transmissions of control information in a control channel. In yet another example, the UE may be configured to determine a transmit power for a transmission in a time interval or scale a transmission in a time interval based on a priority of the transmission relative to other transmissions scheduled in the time interval. In yet another example, the UE may be configured to determine respective transmit powers for uplink transmissions multiplexed differently using different open-loop parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication.

Numerous other aspects are provided.

Abstract: An underwater transmitter may generate underwater pressure waves that encode bits of data. The pressure waves may travel to, and created minute vibrations in, the water's surface. An airborne radar may detect radar signals that reflect from the water's surface. The surface vibrations may modulate the phase of the reflected radar signal. The radar receiver may, based on the variation in the phase of the reflected radar signal, decode the data that was initially encoded in the underwater pressure waves. The underwater pressure waves may be frequency modulated, such as by orthogonal frequency-division multiplexing. Alternatively, the surface vibrations may be detected by a camera, interferometer or other light sensor. Alternatively, the pressure waves may propagate through a media other than water. For instance, the pressure waves may propagate through bodily tissue, or may propagate through oil or a liquid fracking mixture in an oil or gas well.

Abstract: An information processing apparatus includes a control part. The control part performs control to transmit a frame for requesting the transmission of data to an information processing apparatus as a destination of the data and for requesting information processing apparatuses other than the information processing apparatus as the destination to set a transmission inhibition time, the frame being transmitted with transmitting power determined on the basis of surrounding environment information regarding an environment surrounding the information processing apparatus transmitting the frame. Transmission of the frame causes the transmission inhibition time to be set over an appropriate range of information processing apparatuses. Efficiency of utilization of communication resources is improved by suitably setting a transmission inhibition time.
