摘要： A method for controlling inter-cell interference may include receiving a measured uplink interference level through a first backhaul link; determining a transmit power level based on the measured uplink interference level; and sending through a second backhaul link the transmit power level for reconfiguring either a user equipment or a femtocell eNodeB. From the downlink perspective, it may include measuring a downlink interference; and reporting the level of the downlink interference to an ICIC server using a backhaul link. In one example, it may include receiving a measured downlink interference through a first backhaul link; determining a transmit power level based on the measured downlink interference; and sending a message comprising the transmit power level to a femtocell eNodeB using a second backhaul link.

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： UE that are able to cancel interference from CRS, a PDSCH, a PDCCH, or a PCFICH may do so without explicitly signaling the capability to the serving eNB. The serving eNB may transmit to the UE a plurality of cell identifiers to indicate from which cells interference should be canceled. The UE receives CRS, PDSCH, PDCCH, or PCFICH from the serving eNB and cancels CRS, PDSCH, PDCCH, or PCFICH interference, respectively from the signal received from the eNB. The UE cancels the interference from the cells that correspond to the cell identifiers. The UE may then transmit a report to the eNB with a quality measurement without the interference.
摘要翻译： 能够消除来自CRS，PDSCH，PDCCH或PCFICH的干扰的UE可以在不向服务eNB明确地发送能力的情况下这样做。 服务eNB可以向UE发送多个小区标识符，以指示哪个小区应该取消干扰。 UE从服务eNB接收CRS，PDSCH，PDCCH或PCFICH，并分别从eNB接收的信号中取消CRS，PDSCH，PDCCH或PCFICH干扰。 UE消除来自对应于小区标识符的小区的干扰。 然后，UE可以在没有干扰的情况下以质量测量方式向eNB发送报告。

摘要： Certain aspects of the present disclosure relate to techniques for user-specific search space design for multi-carrier operation in Long Term Evolution Advanced (LTE-A) systems. The user-specific search space can be designed for searching Physical Downlink Control Channels (PDCCHs) transmitted on one component carrier (CC) that schedules Physical Downlink Shared Channel/Physical Uplink Shared Channel (PDSCH/PUSCH) transmissions on two or more different CCs. In one aspect, multiple independent user-specific search spaces can be designed. In another aspect, one user-specific search space can be randomly derived and then expanded to accommodate search for multiple CCs. In yet another aspect, the search space design can retain randomness in starting search element indices of multiple PDSCH/PUSCH CCs, while overlapping of search spaces for multiple PDSCH/PUSCH CCs can be avoided.
摘要翻译： 本公开的某些方面涉及用于在长期演进高级（LTE-A）系统中用于多载波操作的用户特定搜索空间设计的技术。 用户特定搜索空间可以被设计用于搜索在两个或多个不同CC上调度物理下行链路共享信道/物理上行链路共享信道（PDSCH / PUSCH）传输的一个分量载波（CC）上发送的物理下行链路控制信道（PDCCH）。 在一个方面，可以设计多个独立的用户特定搜索空间。 在另一方面，可以随机导出一个用户特定的搜索空间，然后扩展以适应多个CC的搜索。 在另一方面，搜索空间设计可以保留多个PDSCH / PUSCH CC的搜索元素索引的随机性，而可以避免多个PDSCH / PUSCH CC的搜索空间重叠。

摘要： Certain aspects of the present disclosure propose methods for reporting information such as a maximum power spectral density to a serving access point after receiving overload indicators from one or more neighboring access points. The reported information may be multiplexed with other information (e.g., Channel Quality Indicator (CQI), Precoding Matrix Index (PMI), rank indication (RI) or acknowledgement (ACK)/negative acknowledgment (NACK) message for downlink data channel) before transmission to the serving access point. In addition, the information may be transmitted in a medium access control (MAC) packet data unit (PDU).

摘要： A user equipment (UE) is configured for carrier aggregation in a wireless communication system. The UE selects control information to be transmitted in an uplink control channel format in a component carrier of two or more component carriers, where the control information includes information types associated with different information reliability requirements. The UE generates an open-loop power control parameter and/or a closed-loop power control parameter based on the information types. The UE transmits the control information in the uplink control channel format at a power level determined by the open-loop power control parameter and/or the closed-loop power control parameter.

摘要： A method and apparatus are for communication in a wireless network in which a User Equipment (UE) associated with a first evolved Node B (eNB) experiences interference from a second eNB. The method includes negotiating by the first eNB of the wireless network with a second eNB of the wireless network for a partitioning of subband resources on an uplink. A first subset of subband resources is assigned to the first eNB, and a second subset of subband resources is assigned to the second eNB. A method and apparatus are for communication in a wireless network. The method includes decoding a downlink control channel received during a protected downlink subframe to determine an uplink subframe n containing a protected subband for uplink transmission. The method also includes transmitting data during the uplink subframe n on the protected subband.

摘要： Discontinuous reception (DRX) operation may be utilized to maintain connection with user equipment (UE) by increasing the effective control channel transmission periodicity. UEs may be configured with a compatible control channel transmission periodicity such that multiple UEs may share a resource in a time-division-multiplexed manner using DRX offsets and periodicity, effectively extending control channel transmission periodicity through resource overloading.
