Abstract: Embodiments of a Machine Type Communication User Equipment (MTC UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The MTC UE may determine a system timing based on reception of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The MTC UE may receive, from the gNB, radio resource control (RRC) signaling that indicates one or more parameters of a configurable resynchronization signal (RSS). The RSS may be for resynchronization, by the MTC UE, after the MTC UE awakens from a power save mode. The parameters of the RSS in the RRC signaling may depend on a target coverage of the MTC UE. The MTC UE may determine an updated system timing based on reception of the RSS.

Abstract: Embodiments may be directed to techniques to determine physical downlink control channel (PDCCH) candidates to assign to a user equipment (UE) based on one or more aggregation levels, each PDCCH candidate in a highest aggregation level of the one or more aggregation levels assigned by a random distribution over a whole control channel element (CCE) domain, and each PDCCH candidate in one or more non-highest aggregation levels of the one or more aggregation levels assigned a random distribution over one or more CCEs utilized by PDCCH candidates of the highest aggregation level. Embodiments also include selecting at least one of the PDCCH candidates to utilize to send downlink control information (DCI) to the UE, and causing transmission of the DCI to the UE via the PDCCH candidates selected.

Abstract: A process for performing a sidelink (SL) communication includes determining a configuration, for a communication zone of a set of communication zones, the configuration being indicative of at least one a resource configuration or at least one signaling configuration for a communication of data. The process includes generating SL control information (SCI) that indicates a transmitter (TX) location based on the configuration of the communication zone of the set of communication zones. The process includes communicating the SCI indicating the TX location.

Abstract: An apparatus for a base station transceiver of a mobile communication system includes at least one interface for communicating with a transceiver module of the base station trans¬ceiver. The apparatus includes a control module configured to provide a reference signal to a user equipment of the mobile communication system via the transceiver module. The reference signal is a reference signal for time tracking. Control module is configured to provide a downlink control signal to the user equipment via the transceiver module. The reference signal and the downlink control signal are quasi-co-located.

Abstract: Techniques are provided for implementing backhaul communications for an integrated access and backhaul node (IAB) operating in a wireless network. For example, an IAB node determines a first random access channel (RACH) configuration for a child node in the wireless network that is served by the IAB node. The IAB transmits a RACH configuration request message including the first RACH configuration to a parent IAB node, and receives, from the parent IAB node, a second RACH configuration complete message that includes a second RACH configuration that is based on the first RACH configuration for the child node. The IAB then performs backhaul communication with the parent IAB node using the second RACH configuration.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for configuring and implementing secondary cell beam failure recovery procedures. For example, some embodiments are directed to a user equipment (UE) that includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to detect that a first beam associated with a secondary cell (SCell) is misaligned. The first beam is associated with a first reference signal (RS). The processor circuitry can further be configured to configure a beam failure recovery (BFR) procedure for the SCell and perform the BFR procedure to replace the first beam with a second beam, wherein the second beam is associated with the SCell.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for determining in a new radio (NR) integrated access and backhaul (IAB) system available soft resources for an IAB node. In one aspect, a method includes determining, by a mobile termination (MT) of the IAB node, a time-domain soft resource configuration for a distributed unit (DU) of the IAB node. The method further includes transmitting the time-domain soft resource configuration to the DU.

Abstract: A method for communicating, by user equipment (UE), on a secondary cell (SCell) with fast activation or deactivation includes obtaining channel state information (CSI) configuration data including a short CSI reporting scheme that indicates a particular number of CSI reports for transmitting on physical uplink control channel (PUCCH) resources by the UE. The method includes sending the particular number of CSI reports on the PUCCH resources in accordance with the CSI configuration data. The CSI configuration data can be received from a serving cell of a new radio (NR) access node (gNB) in a medium access control (MAC) control element (CE) that indicates a status of a short CSI report configuration within a configuration list, and wherein the UE sends one or more of the CSI reports in accordance with the status of the short CSI report configuration.
