    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: A method and apparatus are described for obtaining demodulation reference signal (DMRS) port index information. In one scenario, an evolved Node-B (eNodeB), having a plurality of antenna ports, disables a codeword in a downlink (DL) control indicator (DCI), uses an unused new data indicator (NDI) bit of the disabled codeword as a DMRS port index information field, and transmits the DCI. A wireless transmit/receive unit (WTRU) receives the DCI from the eNodeB and obtains a DMRS port index from the unused NDI bit of the disabled codeword in the received DCI. In another scenario, a DCI including a disabled codeword and a resource allocation header bit in a DMRS port index information field of the DCI is received by the WTRU. The WTRU re-interprets the resource allocation header bit in the DCI as a DMRS port index.

    Abstract translation: 描述了用于获得解调参考信号（DMRS）端口索引信息的方法和装置。 在一种情况下，具有多个天线端口的演进节点B（eNodeB）在下行链路（DL）控制指示符（DCI）中禁用码字，将禁用的码字的未使用的新数据指示符（NDI）位用作 DMRS端口索引信息字段，并发送DCI。 无线发射/接收单元（WTRU）从eNodeB接收DCI，并从接收到的DCI中的禁用码字的未使用的NDI比特获得DMRS端口索引。 在另一种情况下，由WTRU接收在DCI的DMRS端口索引信息字段中包括禁用码字和资源分配标头位的DCI。 WTRU将DCI中的资源分配报头位重新解释为DMRS端口索引。

    Abstract: A method and apparatus of reducing interference in space frequency block coding (SFBC) communication are disclosed. SFBC encoding is performed on at least one pair of symbols. The symbols are assigned to subcarriers in accordance with a frequency assignment pattern assigned to a cell. Different frequency assignment patterns are assigned to neighboring cells. Cells in the network may be divided into a plurality of groups and a different frequency assignment pattern may be assigned to each group of cells. The frequency assignment pattern may be defined such that subcarriers mapped to a pair of symbols in one cell are interlaced to subcarriers mapped to a pair of symbols in a neighbor cell. Alternatively, the frequency assignment pattern may be defined such that subcarriers mapped to a pair of symbols in one cell are shifted in a neighbor cell.

    Abstract: Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.
