Abstract

Systems and methods for dynamically coordinating power allocation in wireless signals is disclosed. In some implementations, a communication system dynamically configures a power level for one or more communicated signals in a multiple transmission-reception point (TRP) environment. The power level may be configured to coordinate single TRP transmission scheme and/or multi-TRP or joint transmission scheme for communicating with a mobile/terminal device.
