摘要： The Long Term Evolution Advanced (LTE-A) network, is a heterogeneous network, where macro and pico base stations (BSs) coexist to improve spectral efficiency per unit area. Systems and methods described herein attempt to provide a solution to the interference coordination problem between macro BSs and pico user equipments (UEs). Specifically, the systems and methods conduct interference coordination based on the concept of almost blank subframe (ABS), which is supported by the LTE-A standard. The macro BSs choose their ABS configurations in a cooperative way such that the overall system throughput is optimized.

摘要： Example implementations are directed to systems and methods based on physical broadcast channel (PBCH) muting are utilized to avoid frequent cell selection/reselection and handover in a LTE-advanced heterogeneous network. In the example implementations, a pico eNB that is fully covered by a macro eNB or other pico eNBs transmits blank PBCH such that it is inaccessible to the UEs who perform cell selection/reselection. Furthermore, a macro eNB may handover a UE to the inaccessible pico eNB by signalling the necessary information to the UE to detect the inaccessible pico eNB. Frequent cell selection/reselection and handover may therefore be avoided in a dense deployment situation.
摘要翻译：示例性实现涉及基于物理广播信道（PBCH）静音的系统和方法，以避免在LTE高级异构网络中频繁的小区选择/重选和切换。在示例实现中，完全由宏eNB或其他微微eNB覆盖的微微eNB发送空白PBCH，使得执行小区选择/重选的UE不可访问。此外，宏eNB可以通过向UE发送必要的信息来检测不可访问的微微eNB，从而将UE切换到不可访问的微微eNB。因此，在密集部署情况下可以避免频繁的小区选择/重选和切换。

摘要： Systems and methods for scheduling multiple user equipments such as mobiles for transmission in the downlink of a cellular communications system. At each scheduling instant the systems and methods return a set of users who should be scheduled based on the past scheduling history of the users, the current individual link gains of the users to the base station, and how the simultaneous scheduling of multiple users affect each other's performance. Since optimal scheduling for communication systems require high computational complexity, low complexity systems and methods are utilized with a performance that is close to the theoretical optimal solution.
