摘要
Systems, methods, and processing nodes are configured to manage data throughput of wireless devices in a wireless network, such as a network that employs MIMO techniques, by receiving a request from a wireless device to operate in the wireless network using a first communication protocol, the wireless network deploying communications with wireless devices using at least two communication protocols simultaneously determining that a value associated with data rate used by a set of wireless devices in the wireless network using at least one of the at least two communication protocols exceeds a threshold value, and adjusting an operating parameter of a multi-element antenna for communicating signals between an access node and the plurality of wireless devices in the wireless network using the first communication protocol when it is determined that the value exceed the threshold value.

As wireless networks evolve and grow, there are ongoing challenges in communicating data across different types of networks. For example, a wireless network may include one or more access nodes, such as base stations, for providing wireless voice and data service to wireless devices in various coverage areas of the one or more access nodes. Wireless networks may be configured to utilize a single-user multiple-in multiple-out (SU-MIMO) operating mode and/or a multi-user (MU-MIMO) mode. In the SU-MIMO operating mode, multiple data streams are directed towards individual wireless devices. In the MU-MIMO operating mode, the multiple data streams can be directed towards plural wireless devices that are selected to participate in the MU-MIMO operating mode based on the orthogonality of transmission, thereby maximizing resources. In a recent evolution of MIMO technology, known as massive MIMO or large-scale MIMO, an access node may utilize hundreds of antennae to simultaneously transmit each of a plurality of different data streams to a corresponding plurality of wireless devices. Massive MIMO has been identified as one of the promising air interface technologies to address the massive data rate or throughput capacity requirement demanded by wireless devices that operate using new communication protocols including, but not limited to, a Fifth Generation mobile networks or wireless systems (5G) protocol.
