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： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： When there are different power classes of base stations (BSs), there may be a need to coordinate transmission from the different BSs to reduce interference to a user equipment (UE) on both control channels and data channels. There are different ways of coordination. For some embodiments, time division multiplex (TDM) resource partitioning may be performed across BSs on a subframe level. TDM resource partitioning may avoid control channel interference since resource mapping on time and frequency for control channels may span the whole frequency domain. However, the data rate for the UE may be limited due to the TDM partitioning of subframes. In other words, a limitation may derive from control channel interference coordination. For some embodiments, a UE may transmit and/or receive in subframes other than the ones partitioned for the UE.
摘要翻译：当存在不同功率等级的基站（BS）时，可能需要协调来自不同BS的传输，以减少对控制信道和数据信道上的用户设备（UE）的干扰。有不同的协调方式。对于一些实施例，可以在子帧级别上跨越BS执行时分复用（TDM）资源划分。 TDM资源分配可以避免控制信道干扰，因为控制信道的时间和频率上的资源映射可能跨越整个频域。然而，由于子帧的TDM划分，UE的数据速率可能受到限制。换句话说，限制可以来自控制信道干扰协调。对于一些实施例，UE可以在除了为UE分配的子帧之外的子帧中发送和/或接收。

摘要： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.
摘要翻译：提供了用于分区资源以增强小区间干扰协调（eICIC）的方法和装置。某些方面涉及广播指示时域资源划分信息（RPI）的消息，其中用户设备（UE）可以在空闲模式下操作。利用RPI，UE可能能够识别来自相邻小区的减少/消除的干扰的受保护资源。该广播消息中的RPI可以被编码为位图，作为U / N / X子帧的枚举的替代或补充。其他方面需要发送指示时域RPI的专用或单播消息，其中UE可以在连接模式下操作。利用RPI，UE可以在受保护的基站期间基于来自服务基站的一个或多个信号来确定信道状态信息（CSI），进行无线电资源管理（RRM）测量或执行无线电链路监视（RLM）时域资源。

摘要： Certain aspects of the present disclosure provide for signaling to expanded capability UEs that may limit the interruption of legacy UEs. According to certain aspects, a base station (e.g., an eNB) may generate and transmit one or more signals containing information that is recognizable by at least one expanded capability UE and identified as invalid by at least one legacy UE. An expanded capability UE may receive such signaling and identifying supplemental information in the signaling, while a legacy UE may regard the signaling as invalid.

摘要： Techniques for reporting channel information are described. In one aspect, a plurality of channel information reporting modes are available to a user equipment (UE) for reporting channel information for coordinated multi-point (CoMP) data transmission. The UE may determine a first channel information reporting mode to use, determine first channel information related to at least one cell in a CoMP measurement set of the UE, and send the first channel information in accordance with the first channel information reporting mode to one or more cells in the CoMP measurement set. The UE may also determine a second channel information reporting mode to use, determine second channel information related to multiple cells in the CoMP measurement set, and send the second channel information in accordance with the second channel information reporting mode. A plurality of channel feedback configurations may be supported, including a single-stage, a two-stage, and/or a one-shot channel configurations.
