This blog post discusses in detail two options for notification of the TS-xApp on the ES actions from the O-RAN specifications perspective. The first option is to utilize the A1 interface to send policies with a “FORBID” clause for cells that will be switched off, to indicate TS-xApp that users should be removed from this cell. The second approach is to utilize the E2SM-CCC, where the TS-xApp listens to the changes in O-CES Management Function.

3GPP Release-19 is the second release of the 5G-Advanced standard. Early workshops on this release were held in June 2023 discussing hundreds of submissions. The original assumption was that 3GPP Rel-19 would primarily focus on investing in the 5G-Advanced commercial deployments to further improve performance and address critical needs. In this post, we’re elaborating on the contents of the selected WIs and SIs to be incorporated within 3GPP Rel-19 as of December 2023.

Energy consumption is a critical aspect of any service in these modern times. In telecommunications, a flexible approach to network planning, control, and management is extremely beneficial in this aspect. The concept of O-RAN enables the creation of algorithms that allow energy saving in a manner independent of the equipment or RAN software solution used. In this blog post, we present an innovative approach to energy saving using the RIC, which is based on the direct cooperation of Traffic Steering xApp and Energy Saving rApp.

In this blog post, we provide the description of an algorithm that can be realized as an rApp in the O-RAN architecture aimed at improving the network’s EE through intelligent RF channels on/off switching. First, we provide a general framework for long-timescale EE optimization which can be done in Non-RT RIC. We then propose the implementation of the RF Channel Switching algorithm within the O-RAN framework. Finally, we discuss some opportunities and challenges.

The baseline 5G system was specified within 3GPP Releases 15 and 16, also known as 5G Phase-1 and 5G Phase 2. There are interesting developments within 3GPP, which evolved the system towards Rel-17. More recently, the standardization took the step towards a significant update with the so-called, “5G-Advanced” using Rel-18 for that purpose. This whitepaper provides an overview of the latest development steps along with outlining the main Work- and Study-Items of both 3GPP Rel-17 and Rel-18 within RAN and SA2 work groups.
