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: Systems, methods, and circuitries are disclosed for determining a position of a wireless device. In one example, an apparatus for a first wireless communication device including baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals is provided. The apparatus includes one or more processors configured to process a signal received from a second wireless communication device to identify at least first arrival path and a different arrival path between the first wireless communication device and the second wireless communication device; and determine a location of the second wireless communication device based on the first arrival path and the different arrival path.

Abstract: Technology for a user equipment (UE) configured for communication of sounding reference signal (SRS) resources is disclosed. The UE can decode a radio resource control (RRC) signal indicating an SRS to transmit with a physical uplink control channel (PUCCH), wherein the PUCCH and the SRS are quasi co located (QCLed) based on a spatial received parameter. The UE can encode an SRS for transmission using the spatial received parameter. The UE can encode uplink control information (UCI) for transmission in the PUCCH using the spatial received parameter. The UE can have a memory interface configured to send to a memory the spatial received parameter.

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.
