Abstract: A method and apparatus for offloading backhaul traffic are disclosed. A first base station may detect a condition triggering backhaul traffic offloading for a wireless transmit/receive unit (WTRU). The first base station may establish a wireless connection with a second base station, and offload at least one bearer of the WTRU onto the second base station via the wireless connection. The first base station may be a macro-cell base station and the second base station may be a femto-cell base station having a wired connection to Internet and a mobile operator core network. The first or second base station may include a relay functionality and act as a relay between the WTRU and the other base station. The backhaul link may be established using a Uu, Un, X2 interface or any other interface over a licensed or license-exempt frequency, a TV white space frequency, etc.

Abstract translation: 公开了一种用于卸载回程业务的方法和装置。 第一基站可以检测触发无线发射/接收单元（WTRU）的回程业务卸载的条件。 第一基站可以建立与第二基站的无线连接，并且经由无线连接将至少一个WTRU的承载卸载到第二基站上。 第一基站可以是宏小区基站，第二基站可以是具有到因特网的有线连接和移动运营商核心网的毫微微小区基站。 第一或第二基站可以包括中继功能，并且用作WTRU与另一基站之间的中继。 回程链路可以使用Uu，Un，X2接口或任何其他接口通过许可或许可证豁免频率，TV空白频率等建立。
