Abstract: Dedicating antenna elements to specific wireless devices by identifying specific wireless devices that meet a set of criteria, such as wireless devices using a certain application type that is associated with a bandwidth, and respectively dedicating a separate portion of antenna elements for communicating with each specific wireless device. The separate portion of antenna elements is selected based on being configured to utilize a bandwidth that meets a threshold bandwidth or matches the bandwidth associated with the application type.

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.

Abstract: Systems and methods provide for assignment of wireless devices to a secondary node based on a characteristic of the wireless device and properties of the secondary node. The method may be triggered when noise reaches a predetermined threshold. HPUEs may be assigned to secondary nodes having a high reverse noise and channels having a high spectral efficiency and LPUEs may be assigned to secondary nodes having a lower reverse noise and a lower spectral efficiency.

Abstract: Subcarrier spacing is selected based on a change in an antenna configuration of an access node, wherein a spectral efficiency of the access node is reduced by the change in the antenna configuration. For example, the change in the antenna configuration is based on the access node deploying additional radio air interfaces using a limited quantity of antenna elements. The subcarrier spacing for at least one radio air interface is increased based on the reduction in spectral efficiency.

Abstract: Load balancing based on pairing efficiency includes monitoring a pairing efficiency metric of each carrier deployed by an access node, the access node being configured to utilize 5G EN-DC, and offloading wireless devices from a first carrier having a lower pairing efficiency to a second carrier having a higher pairing efficiency. Offloading includes adjusting reference signals associated with 4G and 5G carriers.
