Abstract: Methods, processing nodes, and systems are provided for managing relay nodes in a wireless network. A number of relay nodes attached to a donor access node can be determined. A number of latency sensitive wireless devices attached to the relay nodes can be determined. A latency sensitive wireless device can be a wireless device running a latency sensitive application. A latency sensitive relay node can be a relay node attached to the donor access node having an attached latency sensitive wireless device. A maximum number of relay nodes attached to the donor access node can be set, for example, based on the number of latency sensitive wireless devices attached to latency sensitive relay nodes.

Abstract: A method is provided for dynamically modifying a buffer in a network deploying multiple carriers, wherein multiple wireless devices communicate over the network. The wireless devices run applications, each application belonging to an application category. The method includes identifying the application category for a selected wireless device communicating over the network, wherein a first application category requires at least one of high throughput and low latency. The method additionally includes reducing a size of the buffer when the application category is the first application category, thereby initiating carrier aggregation for the selected wireless device.

Abstract: Allocating resources in a wireless network utilizing SU-MIMO and MU-MIMO modes of operation includes determining an increase in a resource usage of MU-MIMO wireless devices and responsive to the determining, reducing an allocation of resources for one or more SU-MIMO wireless devices. These operations may be performed based on determining that a load level associated with a serving access node rises to meet a threshold.

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 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.

Abstract: A wireless network is configured to utilize a multi-user multiple-input multiple-output (MU-MIMO) operating mode. a first subset of wireless devices in a sector that are configured as relay nodes are identified. A second subset of wireless devices in the sector that are not configured as relay nodes are also identified. One or more wireless device in the first subset of wireless devices are instructed, allocated resources, or otherwise controlled to not utilize the MU-MIMO operating mode.

Abstract: A system for dynamically modifying a buffer in a network deploying multiple carriers is provided. Each carrier operating over the network utilizes a radio access technology (RAT). The system includes a network load monitoring processor that measures a network load on carriers using a first RAT to produce a measured value and a buffer management processor that receives the measured value, performs a comparison of the measured value with a predetermined value, and dynamically modifies a size of the buffer when the measured value exceeds the predetermined value.
