Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises a processing circuit configured to determine an NR-physical uplink control channel (PUCCH) resource to be utilized by the UE, for a transmission of a hybrid automatic repeat request (HARQ)-acknowledge (ACK) feedback message to a gNodeB, wherein the determined NR-PUCCH resource comprises a HARQ-PUCCH resource. In some embodiments, the HARQ-ACK feedback message comprises a feedback message generated at the UE in response to processing a downlink (DL) data transmission signal comprising data received from the gNodeB. In some embodiments, the processing circuit is further configured to generate a transmission of the HARQ-ACK feedback message using the determined HARQ-PUCCH resource.

Abstract: 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.

Abstract: Techniques for transmitting and receiving beamformed transmission(s) of a common search space of a DL (Downlink) control channel are discussed. One example embodiment that can be employed at a UE (User Equipment) comprises processing circuitry configured to: select a set of receive beamforming weights for a DL (Downlink) control channel; and decode one or more control channel sets from a common search space of the DL control channel, wherein each control channel set of the one or more control channel sets is mapped to an associated symbol of one or more symbols of a slot, wherein each control channel set of the one or more control channel sets has an associated transmit beamforming, and wherein each control channel set of the one or more control channel sets comprises a common set of control information.

Abstract: 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).

Abstract: 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).

Abstract: An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to select one or more recovery channels based on one or more recovery factors; determine a beam recovery frame structure using the selected one or more recovery channels and based at least partially on beam correspondence capabilities; and provide the selected one or more recovery channels and the determined beam recovery frame structure to the RF interface for transmission to a user equipment (UE) device.

Abstract: 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.
