In a Multi-User Multiple Input Multiple Output (MU-MIMO) radio, networking circuitry transfers MU-MIMO target information to a neighbor radio. The neighbor radio processes the MU-MIMO target information to propose User Equipment (UEs) for handover from the neighbor radio to the MU-MIMO radio. In the MU-MIMO radio, transceiver circuitry determines MU-MIMO channel characteristics for the UEs. Based on their MU-MIMO channel characteristics, the networking circuitry selects some of the UEs from the handover proposals and rejects the other UEs. The transceiver circuitry wirelessly transfers handover acceptance signals to the selected UEs. The transceiver circuitry wirelessly transfers handover rejection signals to the rejected UEs. The transceiver circuitry wirelessly transfers user data to the selected UEs using MU-MIMO.

Handover control for a multi-user multiple input multiple output (MU-MIMO) access point

A wireless access point serve wireless User Equipment (UEs) using Multiple User Multiple Input Multiple Output (MU-MIMO). In the wireless access point, radio circuitry wirelessly receives network signaling from the UEs. Control circuitry processes the network signaling and determines initial power allocations to the UEs and initial MU-MIMO groups of the UEs. The control circuitry processes the initial power allocations and the initial MU-MIMO groups and determines new power allocations and new MU-MIMO groups. The radio circuitry wirelessly transmits MU-MIMO signals to the UEs in the new MU-MIMO groups using the new power allocations.
