Abstract: Certain aspects of the present disclosure propose methods and apparatus to transmit information about number of active UEs in a cell (e.g., pico cell) that need protection to an interfering cell (e.g., a macro cell). The information may be transmitted in a resource status update message. The active users may be defined as users whose downlink performance and/or quality of service are limited by the available number of protected resources.

Abstract: Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering/aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes.

Abstract translation: 无线网络设备之间的干扰问题得到缓解。 当服务于其中UE受到侵略者eNodeB强烈影响的小区范围扩展（CRE）区域中的用户设备（UE）时，演进节点B（eNodeB）可能经历更高的小区负载或更高的干扰。 经历较高小区负载的eNodeB或在更高干扰下的用户设备（UE）通常要求干扰/攻击者eNodeB重新分配其资源中的一些资源。 然而，重新分配资源可能对服务于CRE区域UE的eNodeB产生负面影响。 一方面，新的利用度量度衡量CRE状态，并区分受保护资源和不受保护的资源，如子帧。

Abstract: Methods and apparatus for effectively allocating resource partitioning information (RPI) in a wireless communication network are provided. For certain aspects, a method for wireless communications generally includes receiving, at a first base station, such as a pico enhanced Node B (eNB), resource partitioning information (RPI) from at least one second base station, such as a macro eNB; determining one or more resources indicated in the RPI actually usable by the first base station; and sending, from the first base station to the at least one second base station, an indication of the actually usable resources.

Abstract: One aspect discloses transition behavior of dynamically changing subframe interlaces and the corresponding behavior of the bases stations during the changing. A method of wireless communication includes receiving a request to dynamically change a subframe interlace. The subframe interlace is transitioned and during the transition either new data transmission is prevented on the prohibited subframe interlace and/or retransmissions are allowed on the prohibited subframe interlace.

Abstract: 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.

Abstract translation: 本公开的某些方面涉及用于协作多点（CoMP）操作的回程增强的技术。 攻击者节点可以在基于预调度决定的波束形成的数据传输之前进行预调度决定。 攻击者节点可以例如经由侵略者节点和一个或多个受害者节点之间的回程链路将预调节决定传达给一个或多个受害者节点。 受害者节点可以至少基于攻击者节点的预先调度决策来进行调度决策，以便从来自攻击者节点的波束形成的传输来协调来自受害者节点的波束形成的传输。
