摘要： Communications by base stations in wireless communication networks may be coordinated in a manner to improve performance by mobile devices experiencing interference from non-serving base stations. In particular, base station communications may be coordinated to improve the performance of interference cancellation by mobile devices. If a user equipment (UE) experiencing interference is capable of interference cancellation, then the base stations may coordinate to increase interference to that user equipment so as to improve that UE's ability to perform interference cancellation. Base stations may also coordinate to reduce interference for a UE, regardless of the UE's ability to perform interference cancellation. Mobile device performance improvements may also be achieved by coordinating scheduling of resources by the non-serving base stations, by using communication formats compatible with interference cancellation, by spatial coordination.
摘要翻译：无线通信网络中的基站的通信可以以改善经历来自非服务基站的干扰的移动设备的性能的方式进行协调。特别地，可以协调基站通信以改善移动设备的干扰消除的性能。如果遇到干扰的用户设备（UE）能够进行干扰消除，则基站可以进行协调，以增加对该用户设备的干扰，从而提高UE执行干扰消除的能力。无论UE是否执行干扰消除的能力，基站还可以协调以减少对UE的干扰。还可以通过使用通过空间协调使用与干扰消除兼容的通信格式来协调非服务基站的资源调度来实现移动设备性能改进。

摘要： A frontend receiver of a user equipment (UE) is configured with multiple transform operations assigned to separate sets of cells. One set of cells includes the serving cell of the UE and at least one additional cell within a first offset range of the serving cell. Another set or sets of cells include additional interferer cells within another offset range of the serving cell. After tracking the common frequency/timing offsets of each set of cells the assigned transform operation for that set transforms the time domain samples into frequency domain symbols. The individual frequency/timing offsets for each cell within the set are then tracked.
摘要翻译：用户设备（UE）的前端接收器被配置为分配给单独的单元组的多个变换操作。一组小区包括UE的服务小区和服务小区的第一偏移范围内的至少一个附加小区。另一组或多组单元包括在服务小区的另一偏移范围内的附加干扰信元。在跟踪每组单元的公共频率/定时偏移之后，该组的分配变换操作将时域采样转换成频域符号。然后跟踪集合内的每个单元的各个频率/定时偏移量。

摘要： Aspects of the disclosure are related to identifying whether an apparatus (e.g., base station, access point, etc.) is transmitting using a CRS based transmission scheme or a UE-RS based transmission scheme. Such detection may be necessary for PDSCH interference cancellation (IC) of a neighboring cell since a UE may not know which transmission scheme is used by the neighboring cell. For instance, the UE may know the transmission scheme of the serving cell, but the UE may not know the transmission scheme of a neighboring non-serving cell. As such, aspects of the disclosure provide for a blind detection algorithm to identify or determine a transmission mode or transmission scheme of a neighboring cell to then apply interference cancellation (IC) to an interfering signal received from the neighboring cell.
摘要翻译：本公开的方面与识别装置（例如，基站，接入点等）是否正在使用基于CRS的传输方案或基于UE-RS的传输方案进行传输有关。这样的检测对于相邻小区的PDSCH干扰消除（IC）可能是必要的，因为UE可能不知道相邻小区使用哪种传输方案。例如，UE可以知道服务小区的传输方案，但是UE可能不知道相邻非服务小区的传输方案。因此，本公开的方面提供盲检测算法来识别或确定相邻小区的传输模式或传输方案，然后将干扰消除（IC）应用于从相邻小区接收的干扰信号。

摘要： A delayed channel estimation is a channel state information (CSI) reference subframe having an index (N CSI_ref ) belonging to N CSI_ref = N-4-k; N is the subframe index that the CSI is transmitted on an uplink; and k is the smallest value of k>=0, with N-4-k belonging to a given configuration set. When k is large, the selected CSI reference subframe is too outdated to produce accurate CSI. An undelayed channel estimation is a CSI reference subframe having an index (N CSI_ref ) belonging to N CSI_ref = N-4. When the CSI reference subframe N-4 does not belong to the given subframe restriction subset, the selected channel estimate may be too noisy to produce accurate CSI. A CSI computation method for enhanced inter-cell interference coordination (eICIC) selects between delayed channel estimation and undelayed channel estimation for computing CSI, for example, based on a signal metric. The CSI is computed with a selected channel estimation.
摘要翻译：延迟信道估计是具有属于NCSI_ref = N-4-k的索引（NCSI_ref）的信道状态信息（CSI）参考子帧; N是在上行链路上发送CSI的子帧索引; k是k> = 0的最小值，N-4-k属于给定的配置集。当k大时，所选择的CSI参考子帧太过时，不能产生准确的CSI。未延迟信道估计是具有属于NCSI_ref = N-4的索引（NCSI_ref）的CSI参考子帧。当CSI参考子帧N-4不属于给定子帧限制子集时，所选择的信道估计可能太嘈杂以产生准确的CSI。用于增强小区间干扰协调（eICIC）的CSI计算方法在延迟信道估计和用于计算CSI的未延迟信道估计之间进行选择，例如，基于信号度量。使用所选择的信道估计来计算CSI。

摘要： Techniques for reliable channel decoding in a wireless network are provided. In one aspect, a wireless device receives system information over a physical broadcast channel of a downlink transmission. The wireless device decodes the physical broadcast channel of a current radio frame using a plurality of hypotheses until the decoding passes a cyclic redundancy check. Thereafter, the wireless device compares system information from the current radio frame with information obtained from a previous radio frame. The information from the previous radio frame may include one or more network parameters which may be stored in a memory of the wireless device. In some aspects, the comparison may be performed over a plurality of radio frames. Based at least in part on a result of the comparing, the wireless device may selectively reject system information from one or more of the radio frames.
