When a first access node is considering setup of dual-connectivity service for a UE, the first access node could take into consideration a group delay variation of each of one or more candidate second access nodes, in order to decide whether to set up the dual-connectivity service for the UE and/or to decide which of the multiple second access nodes to use for the UE's dual-connectivity service. For instance, the first access node may decide to use a given candidate second access node for the dual-connectivity service of the UE, with the decision being based on the given candidate second access node having a lower group delay variation than one or more other candidate second access nodes.

A data link quality-based offloading method in dual connectivity includes determining a quality of a bearer link on a user equipment UE side by determining and setting, determining a quality of a radio link by parameters or conditions such as timing advance (TA) timeout, a bit error rate, a signal strength or a signal amplitude, a threshold of continuous scheduling request (SR) sending, a radio link control (RLC) sliding window, a T310 timer, and a triggering of a beam failure recovery process, selecting, based on a determining result, a manner such as a packet replication or selecting a link, and transmitting data through two links.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is connected to a wireless network on a first carrier frequency in a first frequency range that is associated with a lower data rate than a second carrier frequency in a second frequency range. In some aspects, the first frequency range may be associated with a first version of a radio access technology (RAT) and the second frequency range may be associated with a second version of the RAT. The UE may determine a bandwidth metric associated with the first carrier frequency in the first frequency range. The UE may display a first visual indicator associated with the first version of the RAT or a second visual indicator associated with the second version of the RAT based on the bandwidth metric. Numerous other aspects are described.

The device for facilitating network access comprises: a first communication module operable to obtain the network access from a first network provider; a second communication module operable to connect to a communication device, the communication device is operable to obtain the network access from a second network provider; and a processor operable to select at least one of the first communication module and the second communication module to connect to an electronic device; wherein the processor is operable to select the at least one of the first communication module and the second communication module based on a property of a set of executable instructions capable of being accessed by the electronic device.

When a first access node is considering setup of dual-connectivity service for a UE, the first access node could take into consideration the MU-MIMO grouping efficiency respectively of each of one or more candidate second access nodes, in order to decide whether to set up the dual-connectivity service for the UE and/or to decide which of the multiple second access nodes to use for the UE's dual-connectivity service. MU-MIMO grouping efficiency of a given access node could be a representative count of UEs that the access node has provided with MU-MIMO service per unit time. Thus, for instance, the first access node may decide to use a given candidate second access node for the dual-connectivity service of the UE, with the decision being based on the given candidate second access node having a higher MU-MIMO grouping efficiency than one or more other candidate second access nodes.
