    Abstract: Techniques discussed herein can facilitate determination of spatial (and/or beam) assumption(s) for PDSCH (Physical Downlink Shared Channel) transmitted after a BFR (Beam Failure Recovery) request but before TCI (Transmission Configuration Information) reconfiguration. One example embodiment can be an apparatus configured to: generate a BFR request that indicates a new candidate beam; process a CORESET (Control Resource Set)-BFR of a set of configured CORESETs, wherein the CORESET-BFR comprises a response to the BFR request; determine a spatial assumption for a first PDSCH based on the BFR request, wherein the first PDSCH is scheduled by a first CORESET of the set of configured CORESETs, wherein the first CORESET is different than the CORESET-BFR, wherein the first PDSCH is scheduled before a TCI state is one of reconfigured, reactivated, or re-indicated; and process the first PDSCH based on the determined spatial assumption for the first PDSCH.

    Abstract: Embodiments of dynamic multiplexing are described, including the transmission of preemption indication (PI) to indicate preemption of time-frequency resources. In some embodiments, a next Generation NodeB (gNB) is configured to transmit PIs in signaling to preempt an enhanced Mobile Broadband (eMBB) communications transmission with an ultra-reliable and low latency communications (URLCC) transmission. In some embodiments, a user equipment (UE) is configured to monitor a region of time-frequency resources, within a bandwidth part (BWP), for a PI. The PI indicates to the UE a portion of time-frequency resources that omit transmissions intended for the UE. In some embodiments, the gNB transmits the PI to the UE within preemption indication downlink control information (PI-DCI) in a physical downlink control channel (PDCCH) in a control resource set (CORESET). In some embodiments, the BWP is defined according to a frequency domain location, a bandwidth, and a subcarrier spacing for a given numerology.

    Abstract: Embodiments herein may relate to transmission, in a first physical channel transmission, of an indication of a first set of parameters related to a control channel; and transmission, in a control channel transmission using the first set of parameters, of an indication of a second set of parameters related to the control channel. Further embodiments may relate to identifying a first parameter related to interleaving REGBs of a PDCCH transmission, wherein the first parameter is selected from a first plurality of parameters; interleaving the REGBs based on the first parameter to form a CCE; and transmitting the CCE in the PDCCH transmission. Other embodiments may be described and/or claimed.

    Abstract: An eNodeB (eNB), user equipment (UE) and method of providing a flexible Radio Access Technology (FRAT) are generally described. The information (resource allocation, partition information and numerology) of at least one of a plurality of RATs used by the eNB is provided to a UE. Each RAT has a flexible subcarrier spacing and symbol duration, which are integer multiples of a base subcarrier spacing and symbol duration, and is associated with at least one of different temporal and frequency resources. The symbol and/or frame structure of each RAT are independent. A Transmission Time Interval (TTI) boundary between the RATs is common, and the RATs comprise a common reference TTI duration. The information of the RATs is provided either via a different RAT than the RAT used by the UE for communication or via a dedicated carrier in the RAT used by the UE for communication.
