A method and apparatus are provided for artificial intelligence (AI) for communication networks. In one embodiment, a method implemented in a core network node includes collecting location information, the collected location information associated with movement of at least one user equipment within a network; predicting based at least part of the collected location information; and communicating an indication of the prediction.

Artificial intelligence (AI) for communication networks

A method, system and apparatus are disclosed. According to some embodiments, a network node for communicating with a first wireless device is provided. The network node includes processing circuitry configured to: assign a control resource set, CORESET, search area identifier, CS-ID, to a first wireless device, and cause signaling of a CORESET including data for a first wireless device where the data is searchable within the CORESET based at least on an offset derivable from the CS-ID.

Coreset search area optimization

Cell selection by a service group is disclosed. A user equipment (UE) determines that a first cellular service of a plurality of cellular services is desired. The UE accesses service group information that correlates a plurality of service groups to a plurality of cells, wherein each service group is associated with one or more cellular services. The UE initiates a first connection with a first cell of the plurality of cells that can provide the first cellular service based at least in part on the service group information.

Systems and methods relating to transmit patterns that define multiple transmit opportunities for a wireless device in a cellular communications network are disclosed. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises receiving an indication of one or more transmit patterns for one or more logical channel groups. Each transmit pattern of the one or more transmit patterns defines a plurality of transmit opportunities. The method further comprises, based on the one or more transmit patterns, determining when to transmit a scheduling request for transmission of data in accordance with the one or more transmit patterns. The method further comprises, upon determining that it is time to transmit a scheduling request, transmitting a scheduling request to a radio access node to thereby request resources for transmission of uplink data in accordance with the one or more transmit patterns.

Systems and methods for signaling and using transmit patterns

A base station for performing admission control at a service level is provided. The base station includes a communication interface configured to receive a bearer message for a service. The base station includes a processor configured to, in response to receiving the bearer message, determine a plurality of bearers required to support the service. The processor is further configured to determine whether to admit all of the determined plurality of bearers, and in response to determining to admit all of the determined plurality of bearers, admit the service with all of the determined plurality of bearers.

Service aware admission control

A system and method for handling conflicts between periodic resources configured or assigned to a wireless device in a communication network including, in one embodiment, a system and method for determining whether a conflict exists between a first periodic resource occurring with a first periodicity and at least one other periodic resource occurring with a second periodicity in a search region defined based on the first periodicity and the second periodicity, and when a conflict exists, configuring the at least one other periodic resource at a conflict-free position in the search region. By defining the search region based on periodicities of conflicting resources, the present disclosure helps to reduce computations and/or processing time required for identifying and resolving conflicts.

System and method for management of periodic resources in a communication network

Systems and methods relating to direct bit rate adaptation for end-to-end communication via a cellular communications network are disclosed. In one embodiment, a method of operation of a radio access node in a cellular communications network includes obtaining a bit rate associated with a radio bearer between the radio access node and a wireless device. The radio bearer between the radio access node and the wireless device is part of an end-to-end communication path between the wireless device, as a first end-point of the end-to-end communication path, and a second end-point. The method further includes transmitting the bit rate associated with the radio bearer to the wireless device. By transmitting the bit rate associated with the radio bearer to the wireless device, the radio access node controls a bit rate for the end-to-end communication path between the wireless device and the second end-point.

Direct rate adaptation for an end-to-end communication path by a cellular network node

A method for managing congestion on a communication network that includes a network node having a congestion level. Congestion pre-emption criteria corresponding to the congestion level is determined. A list of potential service pre-emption candidates associated with a service pre-emption criteria that is at least equal to the congestion pre-emption criteria is created. The list of potential service pre-emption candidates is at least a sub-set of a plurality of services on the node. A determination is made as to whether to pre-empt at least one of the potential service pre-emption candidates on the list based at least on the service pre-emption criteria.

Communication network congestion control using allocation and retention priority

A method and system for configuring a service at a base station of a wireless communication network are disclosed. According to one aspect, a base station receives from a network node a service identifier that identifies a service to be provided via a plurality of bearers to a user equipment. The base station configures the plurality of bearers according to a service configuration associated with the service identifier.

Wireless communication network bearer management

A method and system for allocating services to a first subscriber of a first home service provider when the first subscriber is visiting a network associated with a visited service provider. A node of the visited network receives a request from the visiting first subscriber to receive a first service from the visited network. In response to the request, the visited network determines whether there are sufficient available resources of a first set of resources to provide the requested first service. When the available resources are insufficient to provide the requested service, then at least one pre-existing service supported by the first set of resources is preempted so that sufficient resources from the first set of resources are made available to provide the requested service, and the requested service is provided to the visiting first subscriber.
