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 configured to periodically transmit a system information broadcast. The system information broadcast may include idle-mode cell reselection thresholds, which may include a set of general cell reselection thresholds and a set of communication-class-specific cell reselection thresholds. The processing circuitry may also periodically transmit a paging broadcast including paging messages for pending communications. One of the paging messages may include information identifying a class of the corresponding pending communication. During cell reselection, a device may determine which of the idle-mode cell reselection thresholds should be used based on which class (if any) is specified in a corresponding paging message.

Abstract: Systems and methods are described for selecting User Equipment(s) (UEs) for pairing in a cellular network. A channel orthogonality of one or more UEs located within a radio range of a first Access Node (AN) may be determined. The one or more UEs may be prioritized for Uplink (UL) Multi-User Multiple-Input-Multiple-Output (MU-MIMO) pairing when a channel orthogonality meets a set channel orthogonality condition. A second AN located within the radio range of the first AN may be detected. At least one of the prioritized UEs located within a radio range of the second AN may be selected for de-prioritization. The prioritized UEs may be paired to share a same set of resource blocks.

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: 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 an amount of packet drops at a shared network device 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 amount of packet drops at the shared network device. The handover paramters may be adjusted to inhibit handovers to the dual connectivity access-node-pair.

Abstract: Methods and systems for adjusting reference signal reporting based on path loss and fading and cell edge conditions experienced by wireless devices in 5G EN-DC networks. As the path loss increases, a period between reference signal reports (or a frequency of reference signal reports) can be increased. This ensures continued quality of service for the wireless devices. Reference signals can include SRS, DMRS, PTRS, etc.

Abstract: Prioritizing air interface resource allocation for relay nodes serving end-user wireless devices with higher bandwidth capabilities, such as 5G and beyond, versus relay nodes serving end-user wireless devices that do not have such capabilities. The bandwidth capability can be based on an average or threshold bandwidth capability of end-user wireless devices. Systems and methods disclosed are implemented in 5G EN-DC heterogeneous networks.

Abstract: A cell site router communicatively coupled to an access node and configured to transmit data between the access node and an external network is further configured to determine a packet loss occurring at a port of the cell site router and adjust a size of a buffer of the cell site router based on the packet loss. The buffer can be associated with the port and/or a RAT associated with the port, and a latency requirement of the data transmission can be considered when adjusting buffer sizes.

Abstract: Systems and methods provide for assignment of wireless devices to an access node based on the transmission power capabilities of the access nodes and the wireless devices. The method may be applied to mobile wireless devices in overlapping coverage areas such that the transmission power capabilities of both the access node and the wireless device are considered during node assignment.

Abstract: A method and system identify a congestion parameter for multiple ports of a cell site router (CSR) and determine a characteristic of a wireless device communicating using the CSR. The method and system further assign the wireless device to a port of the CSR based on the characteristic of the wireless device and the congestion parameter. The method and system have the effect of assigning wireless devices having more capabilities to ports having the most congestion as the more capable devices are more likely to have sufficient retransmission power in the event of congestion.

Abstract: Systems and methods provide inter-band EN-DC coverage combinations to wireless devices in a cell wherein each inter-band coverage has corresponding handover criteria. The method includes determining a power class for at least one wireless device, wherein the power class is one of a high-power class and a low power class. The method additionally includes comparing the handover criteria of at least two inter-band coverage combinations to identify relaxed handover criteria and assigning the high-power class wireless device to an inter-band coverage combination having the relaxed handover criteria.
