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 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: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for resource allocation during initial access. Some embodiments are directed to an apparatus including processor circuitry and radio front circuitry. The processor circuitry can be configured to determine, in accordance with a predetermined requirement, multiple physical resource blocks (PRBs) to be used for transmitting a physical uplink control channel (PUCCH) before a dedicated PUCCH resource configuration. The radio front end circuitry coupled with the processor circuitry can be configured to transmit the PUCCH using the determined PRBs and before the dedicated PUCCH resource configuration. The dedicated PUCCH resource configuration can include initial access before Radio Resource Control (RRC) connection setup.
