Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to reduce an interruption time during a fallback operation resulting from a communication link blockage condition (e.g., a human blockage or other natural/physical wireless blockage). The network device includes a network convergence protocol (NCP) layer that enables communication between other network devices of different radio access technologies (RATs) in a heterogeneous network.

Abstract: A technology is disclosed for an evolved Node B (eNB) operable to transmit a physical downlink control channel (PDCCH) to a user equipment (UE). The eNB can determine a set of configuration indication fields numbered 1 to N, included in a downlink control information (DCI) format Y carried on the PDCCH, where N = ⌊ L format ⁢ ⁢ Y M ⌋ , Lformat Y is equal to a payload size of the DCI format Y, and M is a number of bits of each configuration indication field. The eNB can map the DCI format Y onto the PDCCH. The eNB can transmit to the UE the PDCCH with a cyclic redundancy check (CRC) scrambled by an enhanced interference mitigation and traffic adaptation (eIMTA) Radio-Network Temporary Identifier (RNTI) for the UE.

Abstract: Techniques described herein may be used to enable User Equipment (UE) to efficiently and reliably report supported band combinations to a wireless network. An enhanced NodeB (eNB) may determine eNB-supported bands combinations for carrier aggregation scenarios, create a simplified representation of the eNB-supported bands combinations (e.g., using a highest order band combination, groups of band combinations, etc.), and communicate the eNB-supported bands combinations to the UE. The UE may determine UE-supported band combinations that are among the eNB-supported bands combinations, create a simplified representation of the UE-supported band combinations, and communicate the eNB-supported bands combinations to the eNB. The eNB may use the UE-supported band combinations to allocate appropriate carriers to the UE for carrier aggregation.

Abstract: A wireless communication device is configured to perform resource access in device-to-device (D2D) communication. A user equipment (UE) is provided with processing hardware comprising application processing circuitry and baseband processing circuitry. The application processing circuitry assigns a per-packet priority to data packets in the application layer. The baseband processing circuitry maps the per-packet priority to a transmission priority in the physical layer and prioritizes access to a wireless resource pool depending upon the transmission priority. A UE having the application processing circuitry and baseband processing circuitry is also provided. A computer program product is also provided. An evolved Node B (eNodeB) allocates a resource quota to a UE based upon priority information from the UE corresponding to a D2D communication to be transmitted by the UE. Other embodiments may be described and claimed.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for generating an extended power headroom report (ePHR) based on an uncertainty associated with a physical downlink control channel communication granting an uplink grant for a physical uplink shared channel communication when the system is configured for simultaneous physical uplink shared channel and physical uplink control channel communications. Some embodiments are structured to generate the ePHR using a type 2 report regardless of the uncertainty associated with the ePHR, while other embodiments generate the ePHR using a reference format. In some embodiments, a UE communicates a timing field with a UE capability communication indicating whether the UE meets timing requirements to avoid uncertainty in ePHR communications.

Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

Abstract: A new radio (NR) capable user equipment (UE) to determine whether to skip cellular measurements using s-Measure configuration based on measurements of a synchronization signal (SS) block (SSB) and/or Channel State Information Reference Signal (CSI-RS) using an s-Measure configuration. For example, an s-Measure configuration can include a reference signal received power (RSRP) value and an indicator whether to apply the value to an NR SS block or a CSI-RS. If the value meets or exceeds the measurement for the indicated signal measurement, the s-Measure is satisfied. For example, in an embodiment, the network configures a single s-Measure configuration (e.g., either an NR SS s-Measure configuration or a CSI-RS s-Measure configuration), which when satisfied the UE does not perform further measurements.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, configuration information related to a 2-step random access (RA) procedure between the UE and the gNB in unlicensed spectrum. The 2-step RA procedure may include: an uplink MsgA message that includes, within a random access occasion (RO), a MsgA preamble and a MsgA payload; and a downlink MsgB message that includes, within another RO, a MsgB PDCCH and a MsgB payload. The configuration information may indicate: resources allocated for the MsgA preamble; and a mapping between the resources allocated for the MsgA preamble and the MsgA payload. The UE may determine the resources allocated for the MsgA pay load based on the resources allocated for the MsgA preamble and the mapping.

Abstract: Some embodiments of this disclosure include apparatuses and methods for sidelink connection establishment design to support unicast and groupcast communication for NR V2X in a wireless communication system. The apparatuses and methods include at least generating an announcement of support for a unicast or a groupcast communication for a vehicle-to-everything (V2X) service, generating one or more connection establishment request messages for a secure link establishment to a second UE, to support a V2X communication to enable the V2X service, where the one or more connection establishment request message includes: a first connection establishment request message that is transmitted over a PC5-S interface, and a second connection establishment request message that is transmitted over a PC5-RRC interface. The apparatuses and methods further include at least processing a response message from the second UE that accepts or rejects the connection establishment request message for the secure link establishment.
