Abstract: Methods, apparatus, and systems are provided for signalling transmissions using carriers of different numerologies. In one example, a baseband processor of a base station is configured to perform operations including encoding a first signal to be transmitted on a physical downlink control channel (PDCCH) on a first component carrier with a first subcarrier spacing. The first signal includes downlink control information (DCI) indicating resources for a second signal to be transmitted on a second component carrier with a second subcarrier spacing. Respective numerologies of the first component carrier and the second component carrier are different from one another in accordance with the first subcarrier spacing and the second subcarrier spacing. The baseband processor is configured to cause transmission of the first signal on the PDCCH.

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: In embodiments, a base station may identify a parameter related to a zero power (ZP) resource element (RE) mapping set in a physical resource block (PRB). The ZP RE mapping set may relate to resources that are not to be used to transmit a physical channel transmission. The base station may then transmit, to a user equipment (UE), an indication of the ZP RE mapping set. Other embodiments may be described and/or claimed.

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 and a second circuitry. The first circuitry may be operable to allocate a first set of Resource Elements (REs) for a set of Uplink Control Information (UCI) types corresponding with a first set of frequency resources. The first circuitry may also be operable to allocate a second set of REs for the set of UCI types corresponding with a second set of frequency resources. The second circuitry may be operable to prepare one or more Physical Uplink Shared Channel (PUSCH) transmissions comprising the first set of REs and the second set of REs. A number of REs in the first set of REs may be different than a number of REs in the second set of REs.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.
