Claim of US Patent No. 10,219,279

1. A method of wireless communication by a user equipment (UE), comprising:transmitting a message to a base station, wherein the message includes an emergency status of the UE that indicates whether the UE is in an emergency situation, at least one device-to-device (D2D) group, and a requested transmit power to be used for transmitting data from the UE to the at least one D2D group when the UE is in the emergency situation;
receiving a downlink control information (DCI) message from the base station based on the status, wherein the DCI message includes transmit power control information for D2D communications, wherein the transmit power control information indicates whether the UE can transmit at an allowed transmit power, and wherein the allowed transmit power comprises one of the requested transmit power or a transmit power that is lower than the requested transmit power or lower than a maximum transmission power of the UE; and
transmitting the data to the at least one D2D group based on the transmit power control information received in the DCI message.
