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).

Techniques discussed herein can facilitate configuration and/or multi-beam operation of a NR (New Radio) PRACH (Physical Random Access Channel). One example embodiment employable at a UE (User Equipment) comprises processing circuitry configured to process higher layer signaling indicating a NR (New Radio) random access configuration; generate a random access preamble sequence based at least in part on the random access configuration; map the random access preamble sequence to a set of resources for each of a plurality of sets of beamforming weights; process N RARs (Random Access Responses) associated with the random access preamble sequence, wherein N is an integer greater than one; generate a random access Msg3 (message 3); and map N copies of the random access Msg3 to a PUSCH (Physical Uplink Shared Channel).

Techniques discussed herein can facilitate handling of DL (Downlink) control and data channels having different numerologies in NR (New Radio). One example embodiment comprises an apparatus employable by a UE (User Equipment) configured to generate a report comprising capability information associated with the UE, wherein the capability information indicates whether the UE supports multiplexing of multiple numerologies within a common symbol in a FDM (Frequency Division Multiplexing)-based manner; process first higher layer signaling that configures one or more control resource sets of a NR (New Radio) PDCCH (Physical Downlink Control Channel), wherein the one or more control resource sets are associated with one or more numerologies in accordance with the UE capability information; and demodulate a NR PDSCH (Physical Downlink Shared Channel) from a resource distinct from resources of the NR PDCCH.

Techniques discussed herein can facilitate communication of common control messages via multi-beam operation. Embodiments discussed herein can include BSs (Base Stations) configured to transmit scheduling information associated with a common control message via a beamformed DL (Downlink) control channel in each symbol of two or more symbols of a slot, wherein the DL control channel is one of a dedicated physical channel or a NR (New Radio) PDCCH (Physical Downlink Control Channel); and transmit the common control message via a DL data channel based at least in part on the scheduling information.

Techniques discussed herein can facilitate transmission and reception of group common PDCCH (Physical Downlink Control Channel) for NR (New Radio). One example embodiment employable by a UE (User Equipment) comprises processing circuitry configured to: process higher layer signaling that configures a set of combinations for slot formats for the UE; detect, via blind decoding on at least a portion of a control resource set, a DCI (Downlink Control Information) message that indicates a combination for slot formats of the set of combinations for slot formats via a SFI (slot format indicator); and determine a slot format for one or more slots based on the indicated combination for slot formats, wherein the slot format indicates, for each symbol of the one or more slots, whether that symbol is DL (Downlink), UL (Uplink), or a flexible symbol in the slot format.
