Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

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.

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 apparatus of a Fifth Generation NodeB (gNB) to operate in a License Assisted Access (LAA) system configures a transmission initiation time interval contention window size (CWS) of N number of subframes between Category 4 Listen Before Talk (LBT) uplink (UL) transmissions by a user equipment (UE) operating in the LAA system, and a memory to store a value of N which can have a value 6 or greater or 10 or greater. An apparatus of a UE to operate in an LAA system decodes a configuration from the gNB of a transmission initiation time interval contention CWS of N number of subframes between Category 4 LBT UL transmissions in the LAA system. The CWS is increased to a next higher value when an UL grant or an autonomous UL (AUL) downlink feedback indicator (DFI) is not received before the expiration of a timer.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.
