Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

Abstract: Systems and methods are described for a resource allocation and user multiplexing capacity enhancements for interlace based physical uplink control channel (PUCCH) formats in new radio (NR) using unlicensed spectrum (NR-U). The systems and methods can include at least generating, by the UE, an uplink signal according to a physical uplink control channel (PUCCH) format 2 and having “n” number of physical resource blocks (PRBs) that are mapped in an interlaced manner across a frequency domain on a orthogonal frequency division multiplexing (OFDM) symbol, wherein “n” is an integer multiple of a number of PRBs per interlace, and transmitting, by the UE, the uplink signal over a PUCCH that utilizes unlicensed spectrum in a new radio wireless network.

Abstract: An approach is described for a wireless communication for a fifth generation (5G) or new radio (NR) system. The wireless communication includes a gNode (gNB) configured to indicate a time domain resource allocation within one Discrete Fourier Transform (DFT) size in a downlink control information (DCI), and to transmit a physical downlink shared channel (PDSCH) with a Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in accordance with the time domain resource allocation within the one DFT size.

Abstract: Systems, devices, and techniques for beamforming in wireless communication systems are described. A described technique performed by a user equipment (UE) includes monitoring a downlink reference signal from a base station; transmitting, via a physical uplink shared channel (PUSCH) associated with a hybrid automatic repeat request (HARQ) process number, a beam failure recovery request (BFRQ) in response to a change in a quality of the downlink reference signal, wherein the BFRQ comprises new beam information; receiving, by the UE, a downlink control information (DCI) message to trigger a PUSCH transmission corresponding to the HARQ process number; and transmitting, by the UE after at least a predetermined number of symbols from a last symbol of a physical downlink control channel (PDCCH) reception containing the DCI message, information via a PUCCH in accordance with the new beam information. The UE can apply the new beam information to uplink and downlink channels.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing beam failure recovery. An embodiment operates by detecting a beam failure on a secondary cell (SCell). The embodiment transmits, to a base station, a beam failure recovery request (BFRQ) for the SCell over a primary cell (PCell). The embodiment transmits the BFRQ for the SCell over a Primary Uplink Control Chanel (PUCCH), a Physical Random Access Channel (PRACH), or a Primary Uplink Shared Channel (PUSCH) over the PCell. The embodiment can transmit a schedule request (SR) to allocate a PUSCH over the PCell. The embodiment receives, from the base station, a response for the BFRQ for the SCell over the SCell or the PCell. The embodiment then uses a new beam for the SCell based on the response for the BFRQ for the SCell.
