Abstract: Systems for mitigating interference in a massive MIMO wireless network include an access node, a plurality of antennae communicatively coupled to the access node, and a processor communicatively coupled to the access node. The processor can be configured to perform operations including communicating with one or more wireless devices within a wireless sector utilizing one or more antennae from the plurality of antennae, and monitoring an interference level within the wireless sector. Upon the interference level meeting a threshold, the processor may be configured to utilize fewer antennae to communicate with the one or more wireless devices. Conversely, upon the interference level not meeting the threshold, the processor may be configured to utilize more antennae to communicate with the one or more wireless devices.

Abstract: A pairing efficiency and/or a resource usage associated with wireless devices attached to a sector are monitored. Responsive to determining that the pairing efficiency is below a threshold and/or the resource usage is higher than a threshold, one or more pairing criteria are adjusted to increase MIMO pairing, thereby exploiting the benefits of massive MIMO in wireless networks.

Abstract: Systems, methods, and processing nodes are configured to manage transmission characteristics in a wireless network, such as a wireless network that employs MIMO techniques, by identifying an undesired signal, the undesired signal originating from a communication device external to the wireless network and determining that a signal parameter value of the undesired signal exceeds a threshold value. An operating parameter of a multi-element antenna for communicating signals in the wireless network is adjusted when it is determined that the signal parameter value exceeds a threshold value.

Abstract: Using a scheduler, communication may be scheduled between an access node and a plurality of wireless devices, wherein the plurality of wireless devices comprise one or more relay wireless devices or device to device (D2D) wireless devices. Using the scheduler, at least one relay wireless device or D2D wireless device may be scheduled using a semi-persistent scheduler comprising an adjusted periodicity, wherein a default periodicity used by the semi-persistent scheduler for end-user wireless devices is different from the adjusted periodicity. Data may be communicated between the access node and the at least one relay wireless device or D2D wireless device using the adjusted periodicity.

Abstract: Performing MU-MIMO in a wireless communication network based on determining that a load level of a sector deployed by an access node is below a load threshold, determining that one or more signal conditions within the sector meet a signal threshold, and disabling a MU-MIMO operating mode for wireless devices within the sector. The signal conditions can include current or historical signal conditions. An exemplary current signal condition includes an interference or other signal metric of the at least two wireless devices different by a threshold amount.

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.
