A handover method for managing WBSS vehicle network managed by a WESS-CM includes: recognizing that a vehicle enters an overlapped area between first and second WBSSs; sending, by the first WBSS, a handover recommend request to the WESS-CM; confirming with the second WBSS, by the WESS-CM, whether handover is possible; responding to the WESS-CM, by the second WBSS, the availability of the handover after allocating communication resources; sending, by the WESS-CM, a handover recommend response to the first WBSS; transmitting, by the first WBSS, a handover request message to the vehicle; performing the handover, by the vehicle, by performing reassociation with the second WBSS; and periodically broadcasting, by the vehicle, basic safety message using a T-slot in shared control channel and a T-slot in BSM channel for the second WBSS, while the vehicle is located in the overlapped area.

User circuitry within a wireless User Equipment (“UE”) in need of a network slice or a handoff between cells identifies a slice service type. The user circuitry processes an uplink interference threshold of a target cell based on the slice service type. The user circuitry identifies a preferred operating frequency band based on the slice service type and the uplink interference threshold of the target cell. The user circuitry transfers a service request for a wireless data service having the slice service type over the preferred operating frequency band to network circuitry. The network circuitry wirelessly exchanges data with a wireless access node associated with the target cell over the preferred operating frequency band to establish a packet data unit session comprising the slice service type.

Embodiments include methods, by a first radio access network (RAN) node, for load balancing with a second RAN node. Such methods include receiving, from the second RAN node, one or more first indications related to resource aggregation capabilities for a plurality of cells served by the second RAN node. Such methods include determining one or more of the following based on the first indications: overall capacity available for offloading user equipment, UEs, to the plurality of cells; whether resources from the plurality of cells can be aggregated to meet service requirements of one or more UEs served by the first RAN node; and one or more UEs to be handed over to the second RAN node. Other embodiments include complementary methods by a second RAN node, as well as first and second RAN nodes configured to perform such methods.

A method and a device for session setup and handover in a wireless communication system are provided. The method comprises receiving, from a second node, a message comprising a single network slice selection assistance information (S-NSSAI) of a protocol data unit (PDU) session; and allocating session resources for the PDU session based on the message received from the second node, wherein, in case that the S-NSSAI of the PDU session is supported by the first node, the session resources for the PDU session includes resources related to the S-NSSAI of the PDU session, and wherein, in case that the S-NSSAI of the PDU session is unsupported by the first node or the resources related to the S-NSSAI are unavailable or overloaded, the session resources for the PDU session includes other available resources for the PDU session.

The described technology is generally directed towards a cellular network area optimizer. The area optimizer observes cellular network conditions at multiple radio access network (RAN) nodes within a target area. Based on observed conditions, the area optimizer applies a set of parameter values at the multiple RAN nodes. The set of parameter values enhances the overall throughput, while maintaining or improving connection retainability and accessibility, of the multiple RAN nodes under the observed conditions. The area optimizer learns different sets of parameter values to apply in response to different observed conditions by making parameter value adjustments and observing the effect of the adjustments on overall throughput of the RAN nodes in the target area.

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.
