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: The present disclosure provides for a user equipment (UE) operating in an unlicensed spectrum in time division duplex (TDD). Operating a UE in an unlicensed spectrum in TDD can comprise generating a bitmap message. Generating a bitmap message can include accessing a bitmap comprising a plurality of positions based on a plurality of supported HARQ processes including the HARQ process, mapping a HARQ process identifier (ID) of the HARQ process to a position from the plurality of positions of the partitioned bitmap, and generating a bitmap message comprising the ACK/NACK message in the position of the bitmap corresponding to the HARQ process ID.

Abstract: A number of embodiments can describe the operation of a UE in an unlicensed spectrum. Operating a UE in an unlicensed spectrum can include processing a PDCCH transmission provided by an eNodeB to identify a resource for a transmission of the SR message and based on the resource identified in the PDCCH, generating a PUCCH transmission comprising the SR message for the eNodeB.

Abstract: Technology for a user equipment (UE) operable to decode grant Self-defer less downlink control information (G-D 5 CI) received from a Next Generation NodeB (gNB) is disclosed. The UE can decode the G-DCI received from the gNB in a MulteFire system. The UE can identify grant less uplink DCI components included in the G-DCI. The UE can perform a grant less uplink transmission with the gNB based on the grant less uplink DCI components in the G-DCI received from the gNB.
