摘要： Systems and methodologies are described that facilitate resource management in a wireless communication system. Various techniques described herein can enable a network cell in a wireless communication system (e.g. a macro cell) to mitigate the effects of interference on other surrounding network cells (e.g., femto cells embedded within the coverage of the macro cell). For example, a network cell can allocate control resources that overlap control resources of a nearby cell and assign resources within the region of overlap only to users that will not cause substantial interference to the nearby cell. As another example, a network cell can utilize a control channelization that partially coincides with a control and/or random access channelization of a nearby cell. The network cell can subsequently elect not to use the control resources in the coinciding region in order to enable the nearby cell to control the effects of interference though data scheduling.

摘要： Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.
摘要翻译：本文公开的方面涉及包括eNB和RRH在内的多传输点环境中的信道和干扰估计。在所公开的方面中，一个或多个传输点可以向UE发信号，以基于第一和第二资源模式测量信道状态条件。 UE可以至少部分地基于第一资源模式接收信令并执行干扰估计，以及至少部分地基于第二资源模式来进行信道估计。 UE可以基于干扰和信道估计产生信道状态报告，并将信道状态报告发送到传输点。 eNB可以使用所接收的信道状态报告来调度一个或多个资源供UE使用，并且可以选择或调整第一和第二资源模式上的网络流量，以影响所得到的信道和干扰估计。

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。
