Abstract
A wireless access point controls Carrier Aggregation (CA) based on Multi-User Multiple Input Multiple Output (MU-MIMO). Baseband circuitry selects CA User Equipment (UEs) based on Radio Frequency (RF) signal strengths for the CA UEs exceeding a CA RF threshold. Transceiver circuitry wirelessly transfers user data to the selected CA UEs over CA links. The transceiver circuitry wirelessly transfers user data to MU-MIMO UEs over MU-MIMO links. The baseband circuitry adjusts the CA RF threshold based on changing MU-MIMO UE loading. The baseband circuitry re-selects the CA UEs based on their current RF signal strengths exceeding the adjusted CA RF threshold. The transceiver circuitry wirelessly transfers user data to the re-selected CA UEs using new CA links.
