Abstract: Systems and methods of beam reporting for multiple DL processes are described. A UE receives a beam management processes configuration that provides information about beam management reference signals for beam management procedures. The UE transmits a UE capability report that indicates beam management capabilities of the UE and, later, an indication of whether the UE intends to engage in beam refinement. The UE measures the beam management reference signals and receives a beam reporting message that indicates at least one of the beam management procedures to report. In response, the UE transmits the beam report. The beam report contains beam management reference signal measurements of the beam management procedures indicated by the beam reporting message.

Abstract: Technology for a user equipment (UE) operable to encode a New Radio (NR) short duration physical uplink control channel (PUCCH) for transmission to a Next Generation NodeB (gNB) is disclosed. The UE can identify uplink control information (UCI) for the UE. The UE can multiplex, using frequency division multiplexing (FDM) at the UE, the UCI and a pseudo-random sequence associated with a demodulation reference signal (DMRS) onto a plurality of subcarriers in one or more physical resource blocks (PRBs) of one or more orthogonal frequency division multiplexing (OFDM) symbols. The UE can encode the UCI and the pseudo-random sequence associated with the DMRS multiplexed onto the plurality of subcarriers of the one or more OFDM symbols for transmission on the NR short duration PUCCH to the gNB.

Abstract: Techniques discussed herein can facilitate RS (Reference Signal) sequence generation and mapping, and/or precoder assignment, for NR (New Radio). One example embodiment employable at a NR wireless communication device comprises processing circuitry configured to: generate one or more PN (Pseudo Noise) sequences based at least in part on an initial state of a PN generator; extract, for each PRB (Physical Resource Block) of one or more PRBs, an associated portion of an associated PN sequence of the one or more PN sequences, based at least in part on a reference subcarrier index, independent of a bandwidth part configuration and of a maximum supported number of PRBs; and generate, for each PRB of the one or more PRBs, an associated set of RS(s) for that PRB based at least in part on the extracted associated portion of the associated PN sequence for that PRB.

Abstract: Devices and methods of joint antenna panel switching and beam selection are generally described. A user equipment (UE) can be configured to decode configuration information received via a higher layer for a plurality of receive (Rx) beams for the UE, the configuration information identifying a plurality of Rx beam indices for the plurality of Rx beams. The UE is configured to decode a physical layer (PHY) communication indicating an antenna panel index and an Rx beam index of the plurality of Rx beam indices, the antenna panel index identifying an antenna panel of a plurality of available antenna panels of the UE. The UE is configured to decode a downlink (DL) data transmission, wherein the DL data transmission is received using the antenna panel and a selected Rx beam of the plurality of Rx beams corresponding to the indicated Rx beam index.

Abstract: Technology for a user equipment (UE) operable for quasi-co-location (QCL) is disclosed. The UE can demodulate a synchronization signal (SS) block transmitted by a gNB from a first antenna port, wherein one or more of a Doppler shift, a Doppler spread, an average delay, a delay spread, and spatial receiving parameters are derived from the SS block. The UE can decode a QCL indication that provides an assumption of QCL between a first reference signal of the first antenna port and a second reference signal of a second antenna port. The UE can demodulate the physical channel or the reference signal transmitted by the gNB from the second antenna port, using one or more of the Doppler shift, the Doppler spread, the average delay, the delay spread, and the spatial receiving parameters based on the assumption of QCL.
