Carrier aggregation (CA) control based on multi-user multiple input multiple output (MIMO) usage

A wireless access point uses both Carrier Aggregation (CA) and Multi-User Multiple Input Multiple Output (MU-MIMO). In the wireless access point, processing circuitry determines when Radio Frequency (RF) signal strength for a User Equipment (UE) exceeds a CA threshold. Transceiver circuitry transfer...

Zusammenfassung:	A wireless access point uses both Carrier Aggregation (CA) and Multi-User Multiple Input Multiple Output (MU-MIMO). In the wireless access point, processing circuitry determines when Radio Frequency (RF) signal strength for a User Equipment (UE) exceeds a CA threshold. Transceiver circuitry transfers data to the UE over wireless CA links when the RF signal strength exceeds the threshold. The transceiver circuitry transfers data to the UE over different wireless links when the RF signal strength does not exceed the threshold. The processing circuitry determines MU-MIMO load on the wireless access point. The processing circuitry increases the CA threshold when the MU-MIMO load increases. The processing circuitry decreases the CA threshold when the MU-MIMO load decreases.
