摘要： System(s) and method(s) are provided for inter-cell power control in the presence of fractional frequency reuse in a wireless communication system. Transmission power control of a terminal (210); and ensuing inter-cell interference mitigation, is accomplished by receiving load indicators (23Oi) from non-serving sectors (246i), decoding those load indicators corresponding to the non-serving sectors that operate in the same frequency bands as the terminal, and adjusting the transmission power according to the states of the decoded load indicators in conjunction with the associated non-serving sector forward link signal-to-interference and-noise ratio at the terminal. The states of the load indicators reflect magnitudes of interference metrics with respect to threshold values. Load indicators can also be conveyed by the non-serving sector to a base station (260) serving the terminal through a backhaul (250) communication, and said base station can schedule an adjusted transmission power for the terminal.

A set of physical transmit antennas can be partitioned into a plurality of groups of physical transmit antennas. Further, a precoding vector for a particular group of physical transmit antennas from the plurality of groups of physical transmit antennas can be formulated.

摘要： A delayed channel estimation is a channel state information (CSI) reference subframe having an index (NCSI—ref) belonging to NCSI—ref=N−4−k, where N is the subframe index on which the CSI is to be transmitted on an uplink, and k is the smallest value of k>=0, such that N−4−k belongs to a given configuration set. When k is too large, the selected CSI reference subframe is too outdated to produce accurate CSI.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 (NCSI—ref) belonging to NCSI—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 method for CSI computation for enhanced inter-cell interference coordination (eICIC) selects between a delayed channel estimation and an 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，其中N是要在其上发送CSI的子帧索引上行链路，k是k> = 0的最小值，使得N-4-k属于给定的配置集合。当k太大时，所选择的CSI参考子帧太过时，不能产生准确的CSI。未延迟的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计算的方法例如基于信号度量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。使用所选择的信道估计来计算CSI。

摘要： Power adjustment in the user equipment (UE) includes adjusting the transmission power level for each of multiple transport blocks based on the spectral efficiency associated with the transport block. The UE receives a scheduled transport format parameter for each of multiple transport blocks to be transmitted. Based on those scheduled transport format parameters, the UE determines a transmit power level adjustment for each transport block. The UE will adjust the power according to the determined transmit power level adjustment and transmit each transport block using the adjusted power level.

摘要： A method for discontinuous transmission (DTX) signaling in a physical uplink shared channel (PUSCH) of a wireless communication system includes puncturing at least a portion of a physical uplink shared channel (PUSCH) at a location that would collide with acknowledgement (ACK)/negative (ACK/NACK) feedback if ACK/NACK feedback is transmitted. The method also includes transmitting DTX symbols in the punctured portion of the PUSCH by a user equipment (UE). The method further includes detecting DTX symbols on the PUSCH by an evolved Node B (eNodeB), indicating the UE is operating according to a DTX signaling mode.

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.
