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： In order to cancel any interference due to the second cell signal (e.g., from a non-serving cell) from a signal received at a UE, without receiving additional control information, the UE blindly estimates parameters associated with decoding the second cell signal. This may include determining a metric based on sets of symbols associated with the cell signals in order to determine parameters for the second cell signal, e.g., the transmission mode, modulation format, and/or spatial scheme of the second cell signal. The parameters for the signal may be determined based on a comparison of the metric with a threshold. When a spatial scheme and a modulation format is unknown, the blind estimation may include determining a plurality of constellations of possible transmitted modulated symbols associated with a potential spatial scheme and modulation format combination. Interference cancellation can be performed using the constellations and a corresponding probability weight.
摘要翻译：为了从UE接收到的信号中消除由于第二小区信号（例如来自非服务小区）的任何干扰而不接收附加的控制信息，UE盲目地估计与解码第二小区信号有关的参数。这可以包括基于与小区信号相关联的符号集来确定度量，以便确定第二小区信号的参数，例如第二小区信号的传输模式，调制格式和/或空间方案。可以基于度量与阈值的比较来确定信号的参数。当空间方案和调制格式未知时，盲估计可以包括确定与潜在的空间方案和调制格式组合相关联的可能传输的调制符号的多个星座。干扰消除可以使用星座和相应的概率权重进行。

摘要： Aspects of the present disclosure provide methods and apparatuses for transmitting—from all cells belonging to a cluster (e.g., for Joint Processing/Transmission (JP/T) Coordinated Multipoint (CoMP), also referred to as network MIMO (Multiple Input/Multiple Output))—reference signals (RSs) for channel state information (CSI) feedback to user equipment (UE) at the same time and frequency resources. In this manner, data is precluded from interfering with the CSI feedback scheme. Consequently, data need not be determined to reliably estimate the channel(s).
摘要翻译：本公开的方面提供用于从属于集群的所有小区（例如，用于联合处理/传输（JP / T）协调多点（CoMP））的所有小区进行传输的方法和装置，其也称为网络MIMO（多输入/多输出）） - 用于信道状态信息（CSI）的参考信号（RS），以相同的时间和频率资源反馈给用户设备（UE）。以这种方式，数据被排除在干扰CSI反馈方案之外。因此，不需要确定数据以可靠地估计信道。
