1. A method for wireless communication by a user equipment (UE), comprising:
receiving, from a network node, a first message indicating, for each network power mode of a group of network power modes, a respective group of random-access channel (RACH) process parameters for a RACH process performed in accordance with the respective group of RACH process parameters;
receiving, from the network node, a second message indicating a current network power mode, of the group of network power modes, enabled at the network node;
receiving, from the network node, a third message including a physical downlink control channel (PDCCH) order that initiates the RACH process in accordance with the respective group of RACH process parameters associated with the current network power mode; and
transmitting, to the network node based on receiving the PDCCH order, a RACH preamble associated with the RACH process.
