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： 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： 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 When k is large, the selected CSI reference subframe is too outdated to produce accurate CSI.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： A method for communicating in an advanced long term evolution (LTE-A) network using common reference signal (CRS) resources associated with different interference levels due to resource partitioning is disclosed. Signals are received from an eNodeB indicating a subset of CRS resources for radio link monitoring (RLM) and/or reference signal received power (RSRP) measuring. The subset of CRS resources includes the CRS resources expected to have lower interference from the interfering eNodeBs. RLM and/or RSRP measurements are performed based on the indicated subset.

摘要： Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.

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： 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.

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.
