Abstract

Methods, systems, and devices for wireless communications are described in which a transmitting device may determine a transmit power based on a power state of the transmitting device. A transmitting device may be configured with multiple power configurations, and a particular power configuration may be selected based on a power state and physical layer channel to be transmitted. Based on the selected power configuration, a transmit power may be determined in accordance with a transmit power procedure (e.g., an open loop power control procedure). The configuration may provide, for each physical layer channel (or reference signal), a power offset or delta that is applied in the open loop power control procedure.
