    摘要： Methods are presented wherein a WTRU may determine, based on measurements, that it is a victim of interference from another cell such a closed subscriber group (CSG) cell. In addition, methods are presented for the UE to inform the CSG cell that UE is present and is a victim UE. Methods for informing the CSG cell may include the grant of temporary membership to a victim UE, the use of a connected WTRU as a relay, and/or indicating victim status in a control message. The indication may trigger an interference management procedure. Methods for the WTRU to stop interference management at the CSG cell, methods to allow the use of a training period by the CSG eNB to allow for non-CSG WTRUs to report their presence, and methods to indicate how to perform UE Victim Indication are also presented.

    摘要： Methods, apparatus, and systems using almost blank subframes patterns are disclosed. Different ABS patterns and triggers are described for enabling a wireless transmit/receive unit (WTRU) to obtain ABS patterns. One representative method of scheduling operations by a wireless transmit/receive unit (WTRU) may include the WTRU receiving information indicating the ABS pattern with a plurality of ABS intervals of an interfering cell; determining timing associated with the ABS intervals of the interfering cell in accordance with the indicated ABS pattern; and scheduling a measurement opportunity, a transmission opportunity or a reception opportunity during the ABS intervals of the interfering cell.

    摘要： Embodiments contemplate a wireless transmit/receive unit (WTRU) that may operate in a heterogeneous wireless communication network (HetNet). The WTRU may detect the presence of an extended physical downlink control channel (E-PDCCH) and may decode a physical downlink control channel (PDCCH) upon detecting the E-PDCCH. The WTRU may obtain scheduling information of the E-PDCCH on a physical downlink shared control channel (PDSCH) from the decoded PDCCH. The WTRU may also determine control information for the WTRU from the E-PDCCH using the scheduling information of the E-PDCCH. The HetNet may further include a first eNB and a second eNB and the WTRU may receive the E-PDCCH from the first eNB and another E-PDCCH from the second eNB. The other E-PDCCH may be coordinated with the E-PDCCH such that the interference between the other E-PDCCH and the E-PDCCH from the perspective of the WTRU may be reduced relative to no coordination.

    摘要翻译： 实施例考虑可以在异构无线通信网络（HetNet）中操作的无线发射/接收单元（WTRU）。 WTRU可以检测到扩展物理下行链路控制信道（E-PDCCH）的存在，并且可以在检测到E-PDCCH时解码物理下行链路控制信道（PDCCH）。 WTRU可以从解码的PDCCH获取物理下行链路共享控制信道（PDSCH）上的E-PDCCH的调度信息。 WTRU还可以使用E-PDCCH的调度信息从E-PDCCH确定WTRU的控制信息。 HetNet还可以包括第一eNB和第二eNB，并且WTRU可以从第一eNB接收E-PDCCH，并从另一个eNB接收另一个E-PDCCH。 其他E-PDCCH可以与E-PDCCH协调，使得相对于无协调，可以减少来自WTRU的角度的其他E-PDCCH与E-PDCCH之间的干扰。
