System, methods, and computer-readable media for switching a dynamic radio of a single RU between Radio Access Technology (RAT) protocols based on a Software-Defined RAN intelligent controller (SD-RIC). The SD-RIC efficiently assigning RAN resources by converting a radio access point to either 5G or Wi-Fi based on the load conditions and the number of users seen on the network, so that it appropriately servers the customer and end devices. To determine the load conditions may be based on active users on a particular cell, and then the resource utilization cue is a connection latency. A single radio unit includes a primary radio and a secondary radio, each being independently tuned. The primary radio is static while a secondary one can be influenced based on the conditions, turning into N-RU or Wi-Fi.

Son function for dynamically configured RU in multi-protocol RAN

A method comprises: at a radio access network configured to communicate with a user equipment (UE) wirelessly, an access and mobility management function (AMF), and a positioning service, and through which the UE attached to a network using an attach procedure with the AMF: upon receiving a request for a location of the UE from the positioning service, scheduling resource blocks, configured for acquiring location measurements, across multiple radio units (RUs) of the radio access network, such that the resource blocks are synchronized in time and frequency across the multiple RUs; by the multiple RUs, exchanging, with the UE, the resource blocks as synchronized, and acquiring the location measurements from the multiple RUs based on exchanging; and forwarding the location measurements to the positioning service to enable the positioning service to determine the location of the UE based on the location measurements.

On-demand positioning of 5G devices

A multi-mode radio unit, and more specifically providing a multi-mode radio unit having a 7.2 split mode and a full gNodeB (gNB) mode may be provided. A 7.2 split mode may be executed at a Multi-Mode Radio Unit (MMRU). Next a metric associated with a front-haul link between the MMRU and a Distributed Unit (DU) may be monitored. The metric may be compared to a first threshold, and when the metric is above the first threshold, the MMRU may be caused to switch from the 7.2 split mode to a full gNodeB (gNB) mode.

Multi-mode radio unit

Improved Radio Frequency (RF) performance by optimizing temperature may be provided. A plurality of heatmaps may be created associating a plurality of component heat characteristics, of a plurality of components of a device, with a plurality of pre-defined performance trade-off states. Next, a shortest path through the plurality of pre-defined performance trade-off states may be determined. The device may then be placed in successive ones of the plurality of pre-defined performance trade-off states according to the determined shortest path until a Transmit (TX) performance target is met.

Son function for dynamically configured RU in multi-protocol ran

Disclosed is a method for managing bus channels between a physical layer and a media access channel layer of a network. The method includes determining a current rate of link speed on a media dependent interface side of a physical layer of a network architecture. When the current rate changes to yield a new link speed, the method includes determining a minimal (or near minimal) bus size required to implement the new link speed and switching to the minimal bus size between a physical coding sublayer of the physical layer and a reconciliation sublayer of a datalink layer of the network architecture. The method further includes switching to the minimal bus size between a physical coding sublayer of the physical layer and a reconciliation sublayer of a datalink layer of the network architecture.

System and method for providing power savings in an access point via ethernet rate and interface shifting

Described in example embodiments herein are techniques for implementing power savings in a wireless local area network (WLAN). In accordance with an example embodiment, a centralized controller can be employed to gather data about network activity and select access points to switch to power save mode. Optionally, the controller may designate certain access points to remain active so as to monitor for clients attempting to access the WLAN. An aspect of an example embodiment is that it allows the controller to configure and manage power consumption based on demands on the overall system. In an example embodiment, techniques for implementing power savings within individual hardware components, such as access points, are disclosed. An aspect of a technique described in an example embodiment is that it provides flexibility to balance power savings and performance.

Adjustable data rate data communications may be provided. First, a plurality of remote data rates at which a remote device is configured to operate may be received. Then, a plurality of local data rates at which a local device is configured to operate may be received. A greatest one of the plurality of local data rates may comprise a cable data rate comprising a greatest rate supported by a length of cable connecting the local device and the remote device. Next, an operating data rate may be determined. The operating data rate may comprise a highest one of the plurality of local data rates that has a corresponding equivalent within the plurality of remote data rates. The local device may then be operated at the operating data rate.

Adjustable data rates

Power Over Ethernet (POE)/universal power over Ethernet (UPoE) may be enabled at multigigabit port-channel connections. This may allow for additional speed support in auto-negotiation messages while employing multigigabit speeds. An integrated connector module (referred to herein as a 'ICM') compatible with UPoE with a modified local physical layer (PHY) circuit may be capable of supporting multi-gigabit data rates (such as between 1 G to 10 G, e.g., 2.5 G and 5 G) as to not limit the data rates to 1 G. The ICM may provide multi-gig data transmission through a first plurality of pins comprising a multi-gig data pin area. Furthermore, the ICM may provide UPoE power to support the multi-gig transmission through a second plurality of pins comprising a UPoE power pin area.
