Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB may encode multiple candidate code-block groups to be available for a transmission in unlicensed spectrum, wherein one of the candidate code-block groups is to be transmitted based on a listen-before-talk (LBT) process. Each of the candidate code-block groups may be mapped to a different subset of channels in the unlicensed spectrum. The gNB may determine, based on one or more channel measurements, one or more of the channels that are available for the transmission. The gNB may select, as the candidate code-block group to be transmitted, a candidate code-block group for which the subset of the channels that is mapped to the selected candidate code-block group is included in the one or more channels that are available for the transmission.

Abstract: Embodiments of a distributed antenna system (DAS) and method for enhanced positioning in a wireless network are generally described herein. In some embodiments, an enhanced Node-B (eNB) operates as part of a DAS that includes one or more nodes having the same cell ID as the eNB. The eNB is to transmit a UE-specific reference signal and configure one or more of the other nodes of the cell to transmit UE-specific reference signals that are distinguishable from each other and from the UE-specific reference signal that is transmitted by the eNB. The eNB may receive location estimate information from user equipment (UE) that is determined at least in part from the UE-specific reference signals. The eNB may also configure the nodes to perform cooperative OFDMA transmission techniques for the UEs operating in the cell.
