Abstract

Systems and methods provide cross-layer bearer splitting and cross-RAT retransmission in a RAN-based WLAN/WWAN integrated network. A link aggregation transmitter is configured to receive, from a WLAN stack lower layer protocol, a WLAN transmission confirmation signal and a WLAN congestion status, and to receive, from a WWAN stack lower layer protocol, a WWAN transmission confirmation signal and a WWAN congestion status. The link aggregation transmitter dynamically splits the bearer traffic across the WWAN link and the WLAN link based at least in part on the WLAN transmission confirmation signal, the WLAN congestion status, and the WWAN congestion status.
