摘要： Embodiments include methods for a first network node of a wireless network. Such methods include sending, to a second network node in the wireless network, a first message comprising an indication of predicted future adjustments of mobility-related settings, of the first network node, for mobility of users between a coverage area of the first network node and an adjacent coverage area of the second network node. Such methods include receiving, from the second network node in response to the first message, a second message indicating one or more of the following: acknowledgement, confirmation, or rejection of the predicted future adjustments; and corresponding adjustments of mobility-related settings for the second network node. Other embodiments include complementary methods for a second network node and a third network node, as well as network nodes configured to perform such methods.

摘要： A method, performed by a User Equipment (UE) in dual connected mode is provided. The method is for determining and transmitting an UpLink (UL) Packet Data Convergence Protocol (PDCP) delay. The UE is connected to at least two radio network nodes. The UE determines (430) the delay. The determined delay is associated with each of the radio network nodes to which the UE is connected. The UE then transmits (450), to at least one of the radio network nodes, the determined delay.

摘要： Embodiments include methods for a user equipment (UE) configured for application-layer measurements in a radio access network (RAN). Such methods include receiving one or more configurations of application-layer measurements to be performed by the UE while the UE is connected to the RAN and, in response to an interruption in the UE's connection to the RAN while the CE is configured to perform the application-layer measurements, sending to the RAN a request to resume the UE's connection or a request to reestablish the UE's connection. Such methods also include, in response to the request sent to the RAN, receiving from the RAN a command to setup a new connection to the RAN and in response to the command, releasing the received configurations and discarding any stored application-layer measurement reports. Other embodiments include complementary methods for RAN nodes, as well as UEs and RAN nodes configured to perform such methods.

摘要： Monitoring the performance of an Artificial Intelligence (AI)/Machine Learning (ML) model or algorithm is disclosed herein. In one embodiment, a method performed by a first network node in a radio communication network comprises sending at least one first message to a second network node of the radio communication network, the at least one first message comprising a subscription request to obtain from the second network node one or more historical data elements associated with the AI/ML model or algorithm. At least one second message, comprising one or more historical data elements associated with the AI/ML model or algorithm to be monitored by the first network node, is received from the second network node. At least one performance metric associated with the AI/ML model or algorithm to be monitored is determined based on the one or more historical data elements associated with the AI/ML model.

摘要： Embodiments include methods for a first network node of a wireless network. Such methods include receiving, from a second network node of the wireless network, a first message comprising traffic status information for the second network node and performing one or more of the following operations based on the traffic status information: predicting a change in load and/or interference in a coverage area of the first network node; adjusting configurations of one or more cells and/or one or more beams served by the first network node; requesting the second network node to adjust configurations of one or more cells and/or one or more beams served by the second network node; mobility load balancing with respect to one or more user equipment (UEs) served by the first network node; and configuring one or more UEs served by the first network node to use communication settings that are more robust to interference.

摘要： A computer implemented method for managing resources in a RAN of a communication network is disclosed. The method, performed by a first node in the RAN, comprises obtaining a record of resource status information describing usage, during a historical time period and within a coverage area of the first node, of RAN resources controlled by the first node (2102), and using an ML process to predict, based on the obtained record, resource status information describing usage of RAN resources controlled by the first node within a coverage area of the first node and during a future time period (2104). The method further comprises sending, to a second node in the RAN, a representation of the predicted resource status information (2106). Also disclosed is a method performed by a second node in which the second node uses a received representation of predicted resource status information for RAN resources controlled by a first node in a process relating to management of RAN resources controlled by the second node (2304).

摘要： Systems and methods are disclosed that relate to Quality of Experience (QoE) measurement reporting in a cellular communications system having a split, or distributed, Radio Access Network (RAN) architecture. In one embodiment, a method performed in a RAN having a distributed RAN architecture comprises, at a control plane part of a central unit (CU-CP) of a base station of the RAN, sending one or more first messages to a user plane part of the central unit (CU-UP) to setup or modify one or more bearers and sending one or more second message to a distributed unit (DU) of the base station to setup or modify the one or more bearers.

摘要： A method is disclosed that is performed by a first network node in communication with a second network node. The second network node has been requested or is being requested to send measurements and/or predictions available at the second network node to the first network node. The method comprises receiving, from the second network node, a first message comprising a first indication that sending of measurements and/or predictions from the second network node to the first network node is to be paused, delayed, resumed, or stopped. Also disclosed are a method performed by a second network node, and first and second network nodes.
