Abstract: A system may include an access node to deploy a radio air interface to provide wireless services to one or more wireless devices. The access node may include processing circuitry. The processing circuitry of the access node may monitor a round-trip-time of split-mode communication of a dual connectivity access-node-pair. The processing circuitry of the access node may dynamically adjust one or more handover parameters based on the round-trip-time. The handover parameters may be adjusted to inhibit handovers to the dual connectivity access-node-pair.

Abstract: A method for initiating handover of a wireless device includes identifying a wireless device exhibiting a low power headroom, the wireless device being attached to an access node on a first frequency band, determining a first incidence of packet drops associated with a data transmission from the wireless device on the first frequency band at a cell site router, and determining a second incidence of packet drops associated with another data transmission on a second frequency band of the access node at the cell site router. Based at least in part on the first incidence of packet drops being greater than the second incidence of packet drops, handover of the wireless device from the first frequency band to the second frequency band is initiated. Systems and devices relate to initiating handover of a wireless device.

Abstract: Relaying data comprises assigning a first network address to a relay wireless device attached to an access node, wherein the relay wireless device is communicatively coupled to one or more wireless access points (WAPs); and instructing the relay wireless device to correspondingly assign one or more additional network addresses to the one or more WAPs, wherein the relay wireless device is configured to relay data between the access node and one or more end-user wireless devices attached to any of the one or more WAPs. Port NAT and DHCP are leveraged at the relay UE according to embodiments described herein.

Abstract: One or more elements of a communication system receives a first indicator that a first wireless device is within a first coverage area of a first access node and is also within a second coverage area of a second access node. The first access node and the second access node are both configured to provide a multi-user multiple-input multiple-output (MU-MIMO) operating mode. The communication system determines a first number of wireless devices attached to the first access node that are utilizing the MU-MIMO operating mode. The communication system identifies the first wireless devices as being configured as a relay node. The communication system, based on the first number meeting a first threshold, instructs the first wireless device to attach to the second access node.

Abstract: A system for mitigating interference and improving performance of wireless devices within a sector is in a cellular network is described. The cellular network provides a first and second radio access technology (RAT). The system includes an access node having a processor performing multiple operations. The operations include determining that interference associated with the first RAT within the sector exceeds a threshold interference value and comparing a performance metric of the wireless devices to a predetermined value to determine if the performance metric is below the predetermined value. Upon determination that the performance metric is below the predetermined value and the interference exceeds a threshold value, the processor dynamically limits a number of wireless devices operating using the first RAT within the sector.

Abstract: Selecting a donor access node for a relay node based on a number of component carriers includes identifying one or more potential donor access nodes deploying one or more carriers, measuring a reference signal strength for each of the one or more potential donor access nodes, determining which of the one or more potential donor access nodes deploys a highest number of component carriers, and sending a request to attach to the potential donor access node deploying the highest number of component carriers and having a reference signal strength that meets a reference signal criteria.

Abstract: Exemplary embodiments described herein include systems, methods, and processing nodes for performing load balancing in a wireless network based on a load of a relay node communicatively coupled to a donor access node. Exemplary methods described herein include determining that a traffic load on a relay node meets a threshold, wherein the relay node is configured to relay traffic between an access node and a first one or more wireless devices attached to the relay node, and attempting to offload a second one or more wireless devices attached to the access node and located at a cell edge of the access node.

Abstract: A serving access node is determined as being capable of transmitting a mMIMO signal, responsive to which handover parameters are adjusted for wireless devices attached to the serving access node and receiving the mMIMO signal. Wireless devices attached to a sector deployed by a first access node and not the mMIMO signal are configured to utilize different handover parameters such that the non mMIMO wireless devices request handovers using standard signal level thresholds.

Abstract: Upon satisfying a first handover condition based on signal measurements, an identity of the one or more target access nodes is determined, the identity being associated with a latency, and a determination is made whether or not to execute the handover based on at least the identifier or the latency of the one or more target access nodes. As macrocell access nodes are known to have smaller latency than small access nodes, the macrocell access node is a preferred target, regardless of signal measurements of the small access node. In embodiments, the type or latency of the target access node is weighted higher than the signal measurement for the determination of a preferred target access node. Target access nodes may be assigned priorities based on their type, latency, and signal measurements, and highest-prioritized target access nodes may be preferred as handover targets.

Abstract: A wireless network may have two types of wireless services such as 4G and 5G. The 4G service may not be configured to communicate with wireless devices using multi-user multiple-input multiple-output (MU-MIMO) operating mode, while the 5G service can communicate using MU-MIMO. When a relay node is positioned such that it is within the coverage areas of both types of wireless service, the relay node is instructed to attach to the wireless service that is not capable of utilizing the MU-MIMO operating mode. Conversely, wireless devices within the coverage areas of both types of wireless service that are not configured as relay nodes may be instructed to attach to the wireless service capable of utilizing the MU-MIMO operating mode so that these wireless devices may receive the benefit of utilizing MU-MIMO.
