摘要:
Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.

Embodiments of apparatus and methods for signaling for resource allocation and scheduling in 5G-NR integrated access and backhaul are generally described herein. In some embodiments, User Equipment configured for reporting a channel quality indicator (CQI) index in a channel state information (CSI) reference resource assumes a physical resource block (PRB) bundling size of two PRBs to derive the CQI index.

Apparatus, computer-readable medium, and method to support low complexity user equipment are disclosed. A wireless communication device including circuitry is disclosed. The circuitry may be configured to determine support of a target evolved nodeB (eNB) for a low complexity user equipment (LC-UE), and handover the LC-UE to the target eNB if the support of the target eNB indicates the target eNB supports LC-UE. The wireless communication device may be a long term evolution (LTE) wireless communication device. The wireless communication device may be one of the following a source eNB, a core network entity, a LC-UE, a source radio network controller (RNC), a base station, a source base service set (BSS). The circuitry may be configured to determine support of the target eNB for the LC-UE based on a configuration or information from the target eNB.

Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) interference management. Some embodiments include transmitting a message including a channel quality parameter and a Time-Division-Duplex (TDD) configuration update to at least one other base station of a cellular cell, deciding if the cellular cell is to be operated in a cluster based on the channel quality parameter value, and coordinating an adjustment of uplink-downlink configuration according to a traffic condition.

Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) configuration management. For example, a node may communicate a message including a cell identifier identifying a first cell controlled by the node, and a TDD configuration update to update at least one other node, which controls at least one second cell, with a TDD UL-DL configuration allocated by the node for communication within the first cell.

Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.
摘要:
An apparatus and system to provide a federated learning scheme between a RAN and connected UEs are described. A gNB-DU, gNB-CU, or LMF acts as a central server that selects an AI/ML model, trains the AI/ML model, and transmits the AI/ML model to UEs. The UEs act as local nodes that each send a model request to the central server, receive the AI/ML model in response to the request, trains the AI/ML model locally with data, and report updated parameters to the central server. The central server aggregates parameters from the local nodes and updates the AI/ML model.
