摘要： For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

摘要： Methods and apparatuses are provided that include mitigating interference for devices communicating with femto nodes or other low power base stations by assigning protected resources for communicating therewith. The protected resources can be negotiated with a macrocell base station using interference cancellation. The protected resources can be assigned based on an early or late handover event, which can indicate that the device may be susceptible to interference from the macrocell base station.

摘要： Existing criteria for analyzing radio link failure conditions may not satisfactorily address the conditions between cells that support cooperative resource coordination. Generally, when the UE declares radio link failure, the UE discontinues communication with a serving base station and searches for a new base station. When the UE lies in a region with severe interference, where the interference is coordinated between base stations by the interfering cell yielding part of its resources, the UE measurements for determining radio link failure (RLF) may vary considerably, depending on whether the measured resources were yielded by the interfering cell. When the UE measures resources which were not yielded by the interfering cell, the UE can erroneously declare RLF (e.g., due to high interference), although the UE can still access the serving cell using resources yielded by the interfering cell. Accordingly, disclosed are aspects for determining RLF based by accounting for cooperative resource coordination employing yielded resources.
摘要翻译：用于分析无线电链路故障条件的现有标准可能不能令人满意地解决支持协作资源协调的小区之间的条件。通常，当UE声明无线电链路故障时，UE终止与服务基站的通信并搜索新的基站。当UE位于具有严重干扰的区域中，干扰小区产生部分资源时，基站之间的干扰协调，用于确定无线电链路故障（RLF）的UE测量可能会相当大地变化，这取决于测量的资源被干扰细胞产生。当UE测量不受干扰小区产生的资源时，UE可以错误地声明RLF（例如，由于高干扰），尽管UE仍然可以使用由干扰小区产生的资源来访问服务小区。因此，公开了通过考虑使用产生的资源的协作资源协调来确定RLF的方面。

摘要： Techniques for mitigating data loss during autonomous system information (SI) reading by a user equipment (UE) are described. For autonomous SI reading, the UE may autonomously determine when to read system information from neighbor cells and may not inform a serving cell. In one design, the UE may autonomously select a SI reading gap for reading system information from a neighbor cell. During the SI reading gap, the UE may suspend reception of downlink transmission from the serving cell, receive system information from the neighbor cell, and maintain capability to transmit on the uplink to the serving cell. In one design, the serving cell may determine SI reading gaps autonomously selected by the UE for reading system information from neighbor cells. The serving cell may communicate with the UE by accounting for the SI reading gaps of the UE, e.g., may suspend communication with the UE during the SI reading gaps.

摘要： Certain aspects of the present disclosure relate to techniques for backhaul enhancements for cooperative multi-point (CoMP) operations. An aggressor node may take pre-scheduling decisions in advance of beamformed data transmissions based on the pre-scheduling decisions. The aggressor node may communicate the pre-scheduling decisions to one or more victim nodes, for example, via a backhaul link between the aggressor node and the one or more victim nodes. A victim node may take scheduling decisions based at least on the pre-scheduling decisions of the aggressor node to coordinate beamformed transmissions from the victim node with the beamformed transmissions from the aggressor node.
