Abstract: Techniques for controlling parameters for uplink transmission associated with a device to facilitate improving a communication condition metric(s) (CCM(s)) of the uplink transmission are presented. A communication management component (CMC) can determine whether CCM satisfies a first threshold CCM. If CCM does not, CMC can modify a parameter(s) to reduce a number of resource blocks or an MCS value to improve the CCM. If respective minimum threshold levels have been reached for the number of resource blocks and MCS value, and CCM still is not satisfying the first threshold CCM, CMC can modify a parameter to increase an amount of repetition of data packets for uplink transmission (unless a maximum threshold amount of repetition is reached). If CCM satisfies an applicable threshold CCM for a defined amount of time, CMC can modify parameters to increase the number of resource blocks, increase MCS value, or reduce repetition of data packets.

Abstract: A system information block (SIB) in a radio interface is dedicated to broadcast data intended for Internet of things (IoT) devices. The data can be associated with most any IoT service, such as but not limited to, a vehicle-to-vehicle (V2V) and/or vehicle-to-everything (V2X) service. In one aspect, data, associated with an event, that has been aggregated from one or more IoT devices located within a region can be analyzed to determine a geographical area where a message regarding the event (e.g., accident) is to be broadcast. Further, the message can be dynamically prioritized and/or customized to target a particular class of IoT devices (e.g., connected cars) by employing different message identifiers.

Abstract: Aspects of the subject disclosure may include, for example, identifying a first application executed by a user equipment, computing a first metric associated with an uplink between the user equipment and a base station over a first network, comparing the first metric with a second metric associated with the execution of the first application by the user equipment, and responsive to the comparing, causing the user equipment to connect to the base station via a second network that is different from the first network. 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: 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: Load balancing is facilitated utilizing geographical location and mobility speed. An example method includes receiving, by a first cell device including a processor and associated with a first cell, from a device of devices, information indicative of whether the device has detected cell type information from a second cell device associated with a second cell, wherein at least a portion of the second cell is located within a first boundary of the first cell. The method also includes: determining, by the first cell device, a mobility characteristic of the device, wherein the devices comprise respective mobility characteristics; and selecting, by the first cell device, the device of the devices to associate with the second cell based on the mobility characteristic of the device.

Abstract: Control plane devices are selected by an access point for establishment of end-to-end control plane for a user equipment (UE) coupled to (or requesting to couple to) the access point. In one aspect, the selection is based on data extracted during the setup and/or registration messages communicated between the access point and UE during attachment of the UE to the access point and/or an internal derived mapping of the control pane devices to the access point. In one example, a control plane device pool is segregated to and different sets of control plane devices are selected and utilized to handle traffic associated with different services to improve scaling and flexibility.
