    Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process a configuration transmission carrying a half-tone shifting indicator. The second circuitry may be operable to select one or more subcarrier frequencies for Uplink (UL) transmission based on the half-tone shifting indicator. The third circuitry may be operable to generate a UL transmission for the one or more subcarrier frequencies. The half-tone shifting indicator may have a first value indicating application of a half-subcarrier offset, and a second value indicating no application of the half-subcarrier offset.

    Abstract: An approach is described for a user equipment (UE) configured for a new radio (NR) system with unlicensed spectrum. The UE includes processor circuitry that performs a first channel load measurement at a first frequency of a serving cell and a second channel load measurement at a second frequency of a neighbor cell and associates a report with the first channel load measurement and the second channel load measurement. At least one of the first frequency and the second frequency is in the unlicensed spectrum. The UE also includes radio front end circuitry that is coupled to the processor circuitry and configured to transmit the report to an access node (AN).

    Abstract: An apparatus of a network (NW) configured to: encode a new radio (NR) Discovery Reference Signal (DRS) transmission, the NR DRS transmission including a synchronization signal block (SSB) and channel state information (CSI) reference signal (RS) (CSI-RS). The apparatus is further configured to configure the NW to transmit the NR DRS transmission. The RS-CSI may be a fragmented RS-CSI including a first fragmented portion and a second fragmented portion, where the apparatus is configured to encode a symbol of the NR DRS transmission to comprise the first fragmented portion, a symbol of the SSB, and the second fragmented portion, where the symbol of the SSB is encoded on a physical broadcast channel (PBCH) portion of the NR DRS transmission.

    Abstract: Systems and methods of adjusting contention window size (CWS) in a LBT procedure for both UL and DL unlicensed spectrum transmissions are described. The UE makes a HARQ-ACK determination for at least one code block group (CBG) of a transport block (TB) in a reference burst from a base station, determines whether the HARQ-ACK determination for the CBG meets a predetermined number of NACKs, transmits to the base station a single bit HARQ-ACK feedback for the TB that is dependent on whether the predetermined number of NACKs has been met, and receives or determines the adjusted CWS and uses the adjusted CWS for communication with the base station.
