In certain aspects, a method for wireless communication at a user equipment (UE) includes attempting to receive, from a first base station, data via a first communication link, generating a radio link control (RLC) status report indicating a status of the data at the UE, and transmitting, to a second base station, the RLC status report via a second communication link. The UE may be simultaneously connected to the first base station and the second base station using dual connectivity. In one example, the first base station may be configured as a secondary cell group (SCG) and the second base station may be configured as a master cell group (MCG). In one example, the first communication link may be a New Radio (NR) link and the second communication link may be a Long-Term Evolution (LTE) link.

A wireless User Equipment (UE) controls a wireless data service that is received from a wireless communication network over a radio band. In the wireless UE, a radio wirelessly exchanges user data with the communication network over the radio band to receive the wireless data service. The radio wirelessly receives a communication performance metric from the wireless communication network over the radio band. The communication performance metric characterizes the wireless data service received by the wireless UE over the radio band. In the wireless UE, user circuitry translates the communication performance metric into a service instruction for the wireless UE over the radio band. The radio wirelessly transfers the service instruction for the wireless UE to the wireless communication network over the radio band. The wireless communication network modifies the wireless data service for the wireless UE responsive to the service instruction.

Some aspects of this disclosure relate to apparatuses and methods for communicating in a first radio access technology (RAT) and a second RAT. A user equipment (UE) can receive, from a first base station using the first RAT, first configuration information for the UE to communicate with a second base station via the second RAT; and receive, from the first base station using the first RAT, a downlink message to enable a communication link between the UE and the second base station via the second RAT. The downlink message includes second configuration information for the UE to communicate with the second base station via the second RAT. The UE can establish the communication link between the UE and the second base station using the second RAT based on a link configuration obtained from the first configuration information and the second configuration information.

A user equipment (UE) can receive a first data stream and a second data stream; store data units of the second data stream, as stored data units, in a buffer while a retransmission operation is performed for the first data stream; determine that a threshold is satisfied with regard to the buffer, wherein the threshold is associated with a counter that is maintained based on the storing of the data units; and provide the stored data units based on determining that the threshold is satisfied.

A method for controlling bearers in a core network includes receiving, from a user equipment (UE) device, a request for access to network resources, where the core network is coupled with a primary radio access technology (RAT) and a secondary RAT. The method includes determining an access point name (APN) RAT access restriction in response to the received request, where the APN RAT access restriction associates an APN with a corresponding RAT, where the corresponding RAT comprises at least one of the primary RAT or the secondary RAT. The method also includes assigning a radio bearer based on the determined APN RAT access restriction, wherein the assigned radio bearer exchanges data via the corresponding RAT; and identifying, to a master node, the assigned radio bearer for exchanging data between the UE device and a device specified by the APN via the corresponding RAT.

A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

A method and system for controlling application of split-uplink mode in a wireless communication system including an access node. In an example implementation, a method includes determining a first count defining how many user equipment devices (UEs) are connected with the access node and do not support a split-uplink-mode operation in which uplink user-plane data flow is split between air-interface transmission to the access node and air-interface transmission to another access node. Further, the method includes determining a second count defining how many UEs are connected with the access node as part of dual connectivity and support the split-uplink-mode operation. And the method includes, based on the first count and the second count, controlling whether the access node will allow the split-uplink-mode operation, such as whether the access node will allow new activation of the split-uplink-mode operation.
