Method and apparatus for measuring aggregation latency for LTE - WLAN

摘要

LWA (LTE-WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant capacity and quality of experience (QoE) improvements. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can schedule the PDU either translated over LTE link or WLAN link. The eNB can acquire packet delay information regarding the WLAN link or obtain PDCP layer performance feedback from the UE. As a result, the eNB can adjust PDCP parameter setting and LWA scheduling accordingly.
