The described technology is generally directed towards adaptive spectrum as a service, in which spectrum can be dynamically allocated to adapt to demand for wireless capacity. The demand for wireless capacity can be based on monitoring system state, and/or proactively predicted based on other system state such as time of day. Reallocated spectrum can be monitored for performance, to converge spectrum allocation to a more optimal state. Allocated spectrum can be relocated, increased or decreased, including by the use of citizens band radio service spectrum or other spectrum. Currently allocated spectrum can be adapted into modified allocated spectrum by an application program (xApp) coupled to a radio access network intelligent controller (RIC), a citizens broadband radio service device, a domain proxy service, and/or a user device.

A method, apparatus, and computer program product are provided to manage the establishment of a dual connection. A method according to an example embodiment may include causing a dual connection setup request message to be transmitted to a local area access point (LAAP) and causing a dual connection command to be transmitted to a user equipment (UE). The method further includes receiving a dual connection establishment complete message and causing resources associated with one or more split bearers to be released or suspended.

Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

This application discloses a data traffic management method and apparatus. The method includes: obtaining traffic control information of a first application and a data traffic value used by the first application, where the traffic control information includes at least an upper traffic threshold; and disconnecting a data connection of the first application when the data traffic value used by the first application is greater than or equal to the upper traffic threshold included in the traffic control information of the first application. In the foregoing solution, real-time traffic management on a single application is implemented, so that a user instantly modifies traffic control information according to a requirement, to manage data traffic in real time.

The present disclosure provides a method for link failure recovery during a handover and corresponding user equipment. The method performed in the user equipment (UE) comprises: after a successful handover procedure of the UE configured with a dual active protocol stack, if a radio link failure (RLF) of a master cell group occurs at the UE, then in a radio resource control re-establishment procedure for connection recovery, or when an RLF occurs on a source link, performing, by the UE, an operation of falling back from the dual active protocol stack to a single active protocol stack, releasing a protocol stack and a configuration associated with a source base station; when the link quality of the source base station is good, releasing, by the UE, a protocol stack and a configuration associated with a target base station, resuming a single connectivity state to the source base station, and reporting the failure information to the base station.

Bandwidth parts (BWPs) and other resources for wireless communications are described. A wireless device may use a BWP control procedure and/or a BWP timer management procedure for activating, deactivating, and/or switching BWPs, for example, using multiple active BWPs. A base station may send information comprising one or more fields indicating an action associated with a BWP, for example, if multiple active BWPs are supported. A wireless device may control a first BWP inactivity timer associated with a first active BWP, for example, based on activating, deactivating, and/or switching a second BWP.

Methods and apparatus for flexible bandwidth operation in a wireless communication network are provided. A User Equipment (UE) monitors a first set of resources for a first control channel in a first bandwidth region. In response, to detecting the first control channel, the UE monitors a second set of resources in a second bandwidth region for at least one of control information or data, the second bandwidth region larger than the first bandwidth region, wherein the monitoring the second set of resources for the control information includes monitoring the second set of resources for a second control channel for receiving the control information scheduling resources for receiving the data.
