Abstract: Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

Abstract: Techniques described herein may be used to enable User Equipment (UE) to switch between Radio Access Technologies (RATs) while transitioning from an inactive state to an active state. For example. a UE may connect to a base station via one type of RAT (e.g., Long-Term Evolution (LTE) RAT), enter an inactive state, and later, while transitioning from the inactive state to an active state, connect to another base station via another type of RAT (e.g., a New Radio (NR) or 5th Generation (5G) RAT). The UE may transition from one RAT to another RAT without increasing signaling between the UE and the network beyond minimal signaling involved in a transition of the UE from the inactive state to an active state. The network may further minimize signaling by determining and communicating minimized connection configuration information to the UE.

Abstract: An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors to receive a downlink Protocol Data Unit (DL PDU) from User Plane Function for a user equipment (UE) in a Radio Resource Control Inactive (RRC_INACTIVE) state, wherein the DL PDU includes a Paging Cause to indicate to the UE a reason for the page, and to send the Paging Cause in a paging message to the UE. The apparatus can include a memory to store the paging message.

Abstract: An apparatus of a node of a network comprises one or more baseband processors to process a first user equipment (UE) capability report from a first UE, and to process a second UE capability report from a second UE, wherein the first UE capability report and the second UE capability report include a same UE capability ID for the first UE and the second UE, and wherein the first capability report includes partial UE capability information for the first UE and the second capability report includes partial UE capability information for the second UE. The apparatus can include a memory to store the first capability report and the second capability report.

Abstract: An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).

Abstract: An apparatus of user equipment (UE) comprises one or more baseband processors to process at least one non-public network (NPN) identifier (NPN-ID) broadcast by an NPN and zero or more Public Land Mobile Network (PLMN) identifier (PLMN-ID) broadcast by a PLMN, to compare the NPN-ID against a logical list of NPN-IDs and PLMN-IDs ranked in decreasing order of priority, and to connect with the highest ranked processed NPN or PLMN based on a rank of the NPN-ID in the list. The apparatus can include a memory to store the list of NPN-IDs and PLMN-IDs as a logical list of Equivalent Home Networks or as Operator Controlled Network Selector with Access Technology list.

Abstract: Device to device (D2D) communication can be performed with packet data convergence protocol (PDCP) based encapsulation without internet protocol (IP) addressing. The non-IP D2D PDCP-encapsulated communication can further include two forms of secure data transfer. A first non-IP D2D PDCP-encapsulated communication can be a negotiated non-IP D2D PDCP-encapsulated communication. A second non-IP D2D PDCP-encapsulated communication can be a non-negotiated non-IP D2D communication. The non-negotiated non-IP D2D PDCP-encapsulated communication can include a common key management server (KMS) version and a distributed KMS version. The encapsulated communication can be used with various protocols, including a PC5 protocol (such as the PC5 Signaling Protocol) and wireless access in vehicular environments (WAVE) protocols.

Abstract: A relay device assists in enabling lawful intercept (LI) by reporting, to a LI entity associated with the cellular network, authenticated identities of remote UEs (such as remote UEs connected via proximity services) and identification information that may allow the LI entity to monitor traffic (and/or control statistics related to the traffic) associated with the remote UEs. The authentication of the remote UEs may be performed using a technique that does not require involvement of the cellular network.
