FIG. 11 is an exemplary flow chart of a method of QoS provision for uplink LWA packet for UE perspective in accordance with embodiments of the current invention. In step 1101, a user equipment (UE) establishes a data radio bearer (DRB) with a base station in a wireless network. The DRB corresponds to an evolved packet system (EPS) bearer associated with a QoS Class Identifier (QCI). In step 1102, the UE receives LTE-WLAN aggregation (LWA) configuration from the base station. The UE is connected with both the base station and an LWA-enabled access point (AP). In step 1103, the UE receives access category (AC) information from the network for determining an AC value based on the AC information. In step 1104, the UE performs a channel contention procedure using the AC value and transmitting a data packet to the AP upon winning the channel contention.

Although the present invention has been described in connection with certain specific embodiments for instructional purposes, the present invention is not limited thereto. Accordingly, various modifications, adaptations, and combinations of various features of the described embodiments can be practiced without departing from the scope of the invention as set forth in the claims.
