Abstract: Aspects of the subject disclosure include, for example, identifying a primary serving cell and a secondary serving cell, wherein the primary serving cell facilitates one of attachment, re-attachment or mobility, or any combination thereof, of a mobile device in association with coordination of a wireless service between the primary serving cell, the secondary serving cell and the mobile device. A latency value associated with a message exchange is determined between the primary and secondary serving cells via a messaging interface, and compared to latency requirements, which correspond to a group of mobile service features. A mobile service feature of the group is associated with the wireless service based on the comparison. The wireless service includes a coordinated exchange of wireless signals between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device based on the mobile service feature. Other embodiments are disclosed.

Abstract: Facilitating fast return to stand alone advanced networks (e.g., 5G, 6G, and beyond) after voice fall back is provided herein. Operations of a method can comprise receiving, from a first network device and by a second network device, a connection request that comprises an indication of a fall back procedure. The fall back procedure can be an “RRC release and redirect” or an “IRAT Handover.” The method also can comprise facilitating control of the voice communication for the mobile device and triggering a release of the control of the mobile device from the second network device based on a determination that the voice communication has completed. The fast return procedure can be either a “RRC release and redirect’ or an “IRAT handover.” Further, the method can comprise redirecting the mobile device to a third network device selected based on a capability of the mobile device.

Abstract: When frequency range 1 (FR1) (e.g., Sub6 Ghz radio coverage), and FR2 (e.g., mmW coverage) are present in a given area, there can be a broader coverage from FR1 broadcasting in addition to targeted coverage from FR2 broadcasting. Consequently, FR1 can overlap FR2. To generate system efficiencies, the FR1 and FR2 spectrums can be combined by carrier aggregation (CA) and/or dual connectivity (DC). Thus, a hybrid approach can combine use of both CA and DC, based on radio access network instructions and radio frequency conditions experienced by a user equipment device as it transitions between CA and DC coverage areas.

Abstract: Various embodiments disclosed herein provide for facilitating informing a radio access network of the capabilities of a user equipment device with regard to switching and aggregation of streams received from master and secondary base station devices. Different user equipment device may have different capabilities with regard to aggregated and combining streams received from the base station devices (e.g., split bearer) or switching between the streams (fast switching). The embodiments described herein provide a way for the UE to inform the radio access network about the capabilities of the UE device. In an embodiment, in response to receiving a query from the radio access network, the UE can return via a UE resource capability information element, an indicator indicating the capabilities of the UE device. The indicator can be an integer bit that has different values depending on the capabilities of the UE device.

Abstract: Data can be sent simultaneously on the data links between long-term evolution (LTE) and new radio (NR) for dual connectively. However a mobile device can indicate its capabilities to the network. The mobile device capabilities can comprise the number of total multiple in multiple out (MIMO) layers that the mobile device can support. Because different sectors or markets can have different spectrums that can make use of an increased or decreased number of layers, then assessing the MIMO layer capabilities of the mobile device can allow the network to dynamically adjust the LTE side and the NR side capabilities to optimize network utilization.
