Abstract: The technologies described herein are generally directed toward communicating resource information to a local manager of a group of user equipment devices, for allocation of resources to the group. According to an embodiment, a system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include selecting a first group of resources for a group of user equipment devices. The operations can further include communicating, to a first user equipment device of the group of the user equipment devices, first information corresponding to the first group of resources, the first user equipment device being a first local manager of the group, that communicates second information corresponding to a second group of resources, based on the first information, to respective other user equipment devices of the group, other than the first user equipment device.

Abstract: In a 5G network, a pre-emptive scheduling request (SR) and a pre-emptive buffer status report (BSR) can be used to reduce the latency of data transmissions on the upstream of a multi-hop integrated access and backhaul (IAB) network from the user equipment UE to the IAB-donor node. A centralized unit (CU) can uniformly ensure that the pre-emptive SR/BSR feature is turned on or off across the entire IAB network regardless of which vendor provides the IAB nodes. Additionally, a message can be sent from a gNodeB to the CU to the IAB node to indicate whether the pre-emptive SR/BSR triggering feature is turned on or off.

Abstract: The same or similar physical signals can be used for both user equipment (UE) and an integrate access backhaul (IAB) node. Different configurations of the resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes. In addition, to support topology formation, mobility/multi-connectivity procedures, and backhaul link management, periodic measurements and reports can be configured by a parent IAB node to a child IAB node UE function. This can comprise radio resource management (RRM), radio link monitoring (RLM), and beam management (L1-BM) measurements and reports.

Abstract: Access and user association can be enabled for private and hybrid public/private 5G new radio (NR) networks. More specifically, this disclosure discloses how to perform initial access, user authentication and association, Internet protocol (IP) address assignment for routing, and/or mobility management. The aforementioned process can facilitate the user equipment (UE) to engage in peer-to-peer, local breakout, and private/public network communication, via a local manager (LM) access point, without requiring connectivity to a public radio access network (RAN) or core network.

Abstract: One subscriber identity module (SIM) can transmit data in active mode while another SIM is in an idle mode. However, paging for the SIM in idle mode can occur based on a discontinuous reception configuration (DRX) cycle of the active SIM. For example, when the DRX of the active SIM indicates that the active SIM is in an idle state, then the SIM that is currently in an idle state can send messages and vice versa. The DRX cycle information can be exchanged between a first core network and a second core network. Each core network can belong to the same or different mobile network operator and can have separate radio access networks (RAN) or share the RAN. The DRX cycle information and/or a time-division multiplexing (TDM) pattern can be exchanged over the air via a system information broadcast message.

Abstract: An enhanced handover procedure is provided to facilitate communication routing changes in an integrated access and backhaul (IAB) network. In an IAB network a network node can be connected to the core network via multiple different paths, and when the path changes, (e.g., when an intermediate network node performs a handover procedure with another network node), messages can be sent to relevant network nodes informing them of the route change so as to reduce the number of protocol data units (PDUs) that are transmitted to network nodes that are no longer part of the communication path to the target network node. The network node that is no longer part of the communication path can also inform a parent node of which PDUs have been successfully transmitted to the target network node so that the parent node can retransmit the PDUs that were not transmitted successfully.

Abstract: An example method may include a processing system of a cellular network having a processor receiving, from a mobile endpoint device, a measurement of a performance indicator, a location, and spatial orientation information, the measurement of the performance indicator based upon at least one wireless signal from a base station of the cellular network, and adjusting at least one aspect of the cellular network in response to the measurement of the performance indicator, the location, and the spatial orientation information. Another example method may include a processing system of a mobile endpoint device having a processor receiving a wireless signal from a base station of a cellular network, capturing a measurement of a performance indicator based upon the wireless signal, recording a location and spatial orientation information, and transmitting to the cellular network the measurement of the performance indicator, the location, and the spatial orientation information.

Abstract: The technologies described herein are generally directed toward communicating determined contention levels of resource pools to UEs enabling the UEs to select from available resource pools. According to an embodiment, a system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include assigning determined contention levels to respective ones of a group of resource pools. The operations can further include communicating, to a user equipment device, the determined contention levels, enabling the user equipment device to select a resource pool of the group of resource pools based on the determined contention levels.

Abstract: In a 5G network, an integrated access and backhaul (IAB) deployment in a 5G network, can enable aggregation of multiple user equipment (UE) bearers into backhaul bearers based on factors such as route information of UE bearers and quality of service of UE bearers. Additionally, reconfiguration of backhaul bearers, based on triggers, such as route changes for UE bearers can increase network efficiency for a 5G or other next generation network.
