Abstract: Embodiments of the present disclosure provide a method for improved physical downlink control channel (PDCCH) ordered physical random-access channel (PRACH) transmission in lower-layer triggered mobility (LTM). The method includes receiving a PDCCH order to initiate a PRACH transmission to at least one cell. The method also includes decoding a PRACH transmission index value, where the PRACH transmission index value describes whether the PRACH transmission is an initial transmission or a retransmission, and where the PRACH transmission index value is associated with a target downlink (DL) reference signal (RS). The method also includes determining a random access (RA) preamble power ramping counter value. The method also includes transmitting, based in part on a PRACH transmission power level, the PRACH transmission to the at least one cell, where the PRACH transmission power level is determined based in part on the RA preamble power ramping counter value.
