Abstract: A method and system to control carrier aggregation in a wireless communication system including a first access node and a second access node, where the first access node has a first respective backhaul connection, where the second access node has a second respective backhaul connection, where the first access node supports serving user equipment devices (UEs) with standalone connectivity, and where the first and second access nodes cooperatively support serving UEs with dual connectivity. A method includes detecting that the second respective backhaul connection of the second access node is threshold heavily loaded. And the method includes, based at least in part on the detecting that the second respective backhaul connection of the second access node is threshold heavily loaded, causing the first access node to suppress an extent of carrier-aggregation service that the first access node will provide to any standalone-connected UEs, to help free up capacity for dual-connectivity service.

Abstract: A wireless device, a network node, a core node and methods for handling radio communication of data between the wireless device and the network node in a wireless network. The network node transmits system information related to availability of a potential data bearer dedicated for data tolerating a certain delivery delay, which is received by the wireless device in idle or inactive mode. The wireless device determines whether the potential data bearer is available, based on the system information. When available, the wireless device initiates a transition from idle/inactive mode to connected mode and communicates the data over the potential data bearer. When the potential data bearer is unavailable, the wireless device stays in the idle/inactive mode. When the data is downlink data, the core node sends a paging message indicating a potential data class.
