Abstract
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.
