A receiver receives a radio signal from a transmitter of a wireless communication system serving a plurality of receivers. The radio signal includes for the plurality of receivers served by the transmitter a plurality of control messages and a redundant control message for at least one of the control messages. The receiver detects a control message from the radio signal, and, responsive to detecting the control message, the receiver detects a signal from another location in the radio signal. The receiver determines the detected control message as a specific control message for the receiver based on the signal detected from the other location.

Systems, methods, and instrumentalities are disclosed for switching a control scheme to control a set of system modules and/or modular devices of a surgical hub. A surgical hub may determine a first control scheme that is configured to control a set of system modules and/or modular devices. The surgical hub may receive an input from one of the set of modules or a device located in an OR. The surgical hub may make a determination that at least one of a safety status level or an overload status level of the surgical hub is higher than its threshold value. Based on at least the received input and the determination, the surgical hub may determine a second control scheme to be used to control the set of system modules. The surgical hub may send a control program indicating the second control scheme to one or more system modules and/or modular devices.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be scheduled to send uplink data to a base station using a particular transmission length provided by the base station. The UE may send multiple repetitions of the uplink data to the base station using transmissions that have varying lengths. The UE may determine a transmit power based on the length provided by the base station and use that transmit power for transmitting the repetitions, regardless of the actual lengths of the repetitions.
