摘要： Techniques are described for identifying one or more “interest twins” of a user. An interest twin of a user in another user that has demonstrated interests in items that are the same as or similar to the items in which the user has demonstrated an interest. Various techniques are described for reducing the overhead in interest twin determination operations. Once the interest twins for a user have been identified, the knowledge of the interest twins may be used in a variety of ways to enhance to experience of the user. For example, a mechanism may be provided which allows the user to see a list of items in which the user's interest twins have indicated an interest.

摘要： Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.
摘要翻译：时分复用（TDM）分区是在同频道部署中为异构网络（HetNet）ICIC考虑的小区间干扰协调（ICIC）机制之一。例如，在预分配给演进节点B（eNB）的子帧中，相邻eNB可能不发送，因此可能减少被服务用户设备（UE）经历的干扰。半静态调度（SPS）授权可能具有各种可用的周期性，这可能与TDM分区不兼容。因此，UE可能错过针对UE不可用的子帧调度的SPS机会。因此，在具有TDM分割的异构网络中使用具有小周期的SPS许可可能需要改变，其可以包括调整SPS授权的周期性，基于资源划分信息（RPI）重新安排上行SPS消息，和/或基于当前SPS赠款。

摘要： Blind interference cancellation is described for wireless networks in which a subject base station or cancellation apparatus obtains semi-static information for at least one of its neighboring cells. The base station measures the noise level of each of the neighboring cells based on samples it takes of uplink transmissions in each of the neighboring cells. The neighboring cells are then ranked for interference cancellation based on their relative noise levels. The base station performs discontinuous transmission (DTX) detection to identify at least one interfering user equipment (UE) in the neighboring cell and cancels interference attributable to those identified interfering UEs. The DTX detection and cancelation are then repeated for the remaining neighboring cells in the order they are ranked.

摘要： Certain aspects of the present disclosure propose methods for protecting channel quality indicator (CQI) modulation symbols in a subframe (e.g., a localized frequency division multiplexing (LFDM) subframe). For some aspects, a timing adjustment method may be utilized to adjust time of a UE with respect to an eNodeB. The timing adjustment method may introduce a positive time offset to be used for reducing time mismatch between the UE and the eNodeB. In another aspect, a buffer may be used at the eNodeB to store symbols received by the eNodeB before removing the cyclic prefix information from the subframe. The eNodeB may use the stored symbols and an artificial time delay to ensure that the CQI information is protected. For some aspects, the CQI modulation symbols may not be located at the beginning of an LFDM symbol.
摘要翻译：本公开的某些方面提出了在子帧（例如，局部频分复用（LFDM）子帧）中保护信道质量指示符（CQI）调制符号的方法。对于一些方面，可以利用定时调整方法来调整UE相对于eNodeB的时间。定时调整方法可以引入正时间偏移，以用于减少UE与eNodeB之间的时间失配。在另一方面，可以在eNodeB处使用缓冲器来存储由eNodeB接收的符号，然后从子帧中删除循环前缀信息。 eNodeB可以使用存储的符号和人造时间延迟来确保CQI信息被保护。对于一些方面，CQI调制符号可能不位于LFDM符号的开头。

摘要： Techniques for performing rank-dependent precoding for a MIMO transmission are described. Each rank may be associated with a set of at least one precoding vector or matrix that can provide good performance for that rank. A transmitter may obtain a precoding vector for a rank-1 transmission from a first set containing at least one column vector of a unitary matrix, e.g., a Fourier matrix. The transmitter may perform precoding for the rank-1 transmission based on the precoding vector. The transmitter may obtain a precoding matrix for a rank-2 transmission from a second set containing an identity matrix. The transmitter may perform precoding for the rank-2 transmission based on the precoding matrix. For the rank-2 transmission, the transmitter may select the identity matrix as the precoding matrix if a MIMO channel resembles a diagonal channel (which may be determined based on antenna configurations) and may select the unitary matrix otherwise.
摘要翻译：描述用于执行MIMO传输的等级相关预编码的技术。每个等级可以与可以为该等级提供良好性能的至少一个预编码向量或矩阵的集合相关联。发射机可以从包含单一矩阵的至少一个列向量（例如傅立叶矩阵）的第一集合获得用于秩1传输的预编码向量。发射机可以基于预编码向量来执行秩1传输的预编码。发射机可以从包含单位矩阵的第二集合获得用于秩-2传输的预编码矩阵。发射机可以基于预编码矩阵来执行秩2传输的预编码。对于秩2传输，如果MIMO信道类似于对角信道（可以基于天线配置确定），则发射机可以选择单位矩阵作为预编码矩阵，否则可以选择酉矩阵。
