Techniques discussed herein can facilitate power ramping of PRACH (Physical Random Access Channel), for example, in connection with change of best gNB (next generation Node B) Tx (Transmit) beam and/or dynamic beam switching for control and/or data channels. Power ramping techniques discussed herein can comprise techniques for determining at least one of a power ramping counter or power offset for PRACH in connection with a change in best DL (Downlink) Tx (Transmit) beam. Dynamic beam switching techniques discussed herein can comprise employing DCI comprising at least one beam indication field indicating a beam index of a new beam of a BPL (Beam Pair Link) for at least one of a data channel or a control SS (Search Space).
