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 When k is large, the selected CSI reference subframe is too outdated to produce accurate CSI.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： 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 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.

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： 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： Incremental interference cancelation (IC) capability management and signaling is disclosed. A mobile device selects certain groups of its individual IC capabilities to deactivate in response to various operating conditions it is experiencing. The mobile device reports its currently active IC capability to a serving base station, which uses information to determine whether to modify any existing communication conditions with respect to the reporting mobile device. The base station detects and analyzes the current communication conditions with respect to the reporting mobile device in light of the mobile device's currently active IC capabilities. The base station may modify such conditions through actions such as signaling the mobile device to activate or deactivate certain other groups of IC capabilities. The base station can make other modifications such as changing the communication schedule for the mobile device, modifying the control loop for channel quality indicator (CQI) reporting, and the like.
