System and methods for using channel quality reports to reduce inter-band interference are disclosed. Channel information is received at a first wireless communication device from a second wireless communication device. The first wireless device is operating in a first frequency range, and the second wireless device is operating in a second frequency range. The first frequency range is adjacent to the second frequency range. A channel quality report is generated at the first wireless communication device. The channel quality report indicates that particular sub-bands in the first frequency range have low channel quality. The particular sub-bands are selected using the channel information.

LTE transmission mask adjustment to maximize performance and reduce interference

A radio controller entity is in communication with a centralized control plane entity of a disaggregated base station, or with a monolithic base station, the disaggregated base station or monolithic base station serving wireless user equipment in a wireless network. The radio controller entity obtains from the centralized control plane entity or from the monolithic base station, a context associated with one or more user equipment served by the disaggregated base station or the monolithic base station. The radio controller entity determines a policy to be set. The policy defines a set of one or more rules, each rule including a condition and an action. The rule may include that the base station should query the radio controller for an instruction as to which action(s) to apply. The radio controller entity provides the policy to the centralized control plane entity or to the monolithic base station.

Procedures for interaction between the radio controller and the subordinated base station

Systems and methods are provided by which a radio controller, also called a radio intelligence controller (RIC), is configured as a platform that hosts one or more third party applications. The radio controller platform provides the applications with access to radio access network (RAN) information and a command interface. An application programming interface is defined between the applications and the radio controller. The radio controller collects information from the RAN node and makes that information available to the applications. The applications also provide input information to the radio controller, such as in the form of a commands or a radio controller policy. The radio controller policy rules from the applications are executed by the radio controller or direct the radio controller to query one of the applications for an instruction.

Interaction between radio controller platform and third party applications

A method for cross-domain service optimization is implemented on a computing device and includes defining at least one key quality indicator (KQI) target for at least one end-to-end (E2E) service, where the at least one E2E service crosses more than one domain of a communications network, receiving an indication of quality of experience (QoE) for the at least one E2E service, based on the indication of QoE, translating the at least one KQI target to at least one set of service optimization instructions for each domain from among the more than one domain, and for each domain, applying the service optimization instructions.

Cross-domain service optimization

A Centralized Self Organizing Network (C-SON) automation platform for managing a backhaul infrastructure in a telecommunication network. The C-SON automation platform monitors one or more backhaul utilization performance indicators corresponding to a backhaul infrastructure, which infrastructure transports data between one or more User Equipment (UE) connected to a small cell and a data network. The C-SON further receives subscriber data for at least one User Equipment (UE) and location data for the at least one UE from at least one Network Function (NF), and maps the at least one UE to a backhaul service flow and the small cell based on the subscriber data and the location data. The C-SON automation platform determines the backhaul utilization performance indicator exceeds a backhaul threshold limit for the backhaul service flow, and adjusts a bandwidth utilization of the backhaul infrastructure based on the backhaul utilization parameter exceeding the backhaul threshold limit.

Techniques for adapting Self-Optimizing Networking (SON) applications for Narrowband Internet-of-Things (NB-IoT) deployments in wireless networks. A controller is provided for a wireless network that includes a plurality of base stations. At least one of the base stations serving wireless communication for both a first cell type of wireless user devices and a second cell type of NB-IoT devices. The controller applies SON applications to the wireless network, and monitors performance of wireless communication in the first cell type and the second cell type associated with one or more base stations affected by the SON applications. The controller modifies or reverts the actions taken by the SON applications on the wireless network based on the performance monitoring.

Disclosed embodiments include a base station. The base station includes a receiver that receives a channel quality report identifying one or more particular sub-bands in a first frequency band that, when used to transmit information, causes interference in one or more channels of a second frequency band that is adjacent to the first frequency band. The base station further includes a processor that selects one or more sub-bands in the first frequency band to assign based on the channel quality report, the selected sub-band(s) avoiding the one or more particular sub-bands identified in the channel quality report. Additionally, the base station includes a transmitter that sends a sub-band assignment for the selected sub-band(s). The first frequency is a Long Term Evolution (LTE) frequency and the base station is an eNodeB base station in one embodiment.
