A system for enhancing an energy efficiency of a mobile network includes a digital twin connected to the mobile network. The digital twin is programmed to: receive, from the mobile network, real-time network traffic data and base station data of base stations operating in the mobile network; generate a first prediction of network traffic at a first time-scale based on the real-time network traffic data; generate a second prediction of network traffic at a second time-scale based on the real-time network traffic data and the base station data; and generate a first power consumption prediction for the mobile network based on the first prediction, the second prediction, and a topology of the mobile network, and the digital twin emulates at least a portion of the mobile network.

Method and system for using a digital twin of a mobile network to provide energy efficiency

Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.

Discovery signal generation and reception

One example method includes using a network digital twin of a communications network to perform operations including monitoring, on an ongoing basis, a status of the communications network as the communication network changes, maintaining synchronization between the communications network and the network digital twin based on changes to the status, and the status changes are determined using information gathered during the monitoring, and using the network status to make a prediction regarding performance of the communications network.

Methods and processes to enable RNN-GNN-based network digital twin for O-RAN

The technology described herein is directed towards a distributed cross-layer intelligent beam management engine that performs a beam alignment procedure, including learning a site-specific probing codebook and using probing codebook measurements to predict an optimal narrow beam using an AI/ML method. The learned codebook determines site-specific probing beams that can capture particular characteristics of the propagation environment. The distributed engine includes distributed applications with different delay requirements that perform different parts of the beam alignment procedure. One application (e.g., in a non-real time controller) provides probing codebook policy data and reporting policy data, and another application (e.g., in a near-real time controller) learns the probing codebook based on the policy data. A third, real time application performs the beam sweeping based on the probing codebook, with the optimal beam for a user equipment identified by the user equipment.

Cross-layer intelligent beam management engine

A method for WTRU autonomous resource selection may comprise receiving a TX resource pool for D2D communication from a base station. The WTRU may sense one or more resources of the TX resource pool and determine resources for transmission of control information and D2D data, based on the sensing. The WTRU may then transmit, to another WTRU, the control information and the D2D data on the determined resources.

Methods to enable scheduling and control of direct link communication in cellular communication systems

Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

Method and apparatus for performing device-to-device discovery

Systems, methods, and instrumentalities are provided to implement scheduling for device-to-device (D2D). A WTRU (e.g., a D2D WTRU) may determine whether the WTRU has D2D data to transmit. The WTRU may determine a set of allowed SA resources and/or allowed D2D data resources for transmission of the SA. The WTRU may select an SA resource and/or D2D data resources (e.g., from the set of allowed SA resources and/or D2D data resources) for transmission. The WTRU may select one or more transmission parameters. The WTRU may select one or more transmission patterns. The WTRU may transmit D2D data over the set of allowed D2D resources using the selected transmission patterns and according to the selected transmission parameters.

Distributed scheduling for device-to-device communication

Device-to-device (D2D) cross link power control systems and methods may be disclosed. For example, a device such as a UE or WTRU may determine whether it may have simultaneous transmissions where at least one of the transmissions may include a cross link transmission. The device may further determine whether a total transmit power of the simultaneous transmissions may exceed a maximum transmit power of the device. If the device may have simultaneous transmissions and such transmissions may exceed the maximum transmit power, the device may reallocate power based on a priority or priority setting. The device may further determine a maximum cross link power, a maximum device power, and a cross link transmit power level such that the device may further control the power for transmissions based thereon.
