摘要： Systems and methodologies are described that facilitate indicating a dominant interferer to a target serving base station in a wireless communication environment. A mobile device can detect presence or absence of a dominant interferer. Further, an access probe that includes information related to the presence or absence of the dominant interferer can be generated. For example, the information can be included in a payload of the access probe as an explicit flag, an explicit indication of an interference level, a Channel Quality Indicator (CQI) value (e.g., reserved versus non-reserved,...), etc. Moreover, the access probe can be transmitted to the target serving base station to initiate an access procedure. The target serving base station can select a time-frequency resource to be utilized for a responsive downlink transmission (e.g., access grant signal, subsequent access related message,...) as a function of the information included in the access probe.

摘要： Techniques for transmitting null pilots to support interference estimation in a wireless network are described. A null pilot is non-transmission on designated time-frequency resources by a cell or a cluster of cells supporting cooperative transmission to a UE. The received power of the null pilot from the cell or cluster of cells may be indicative of interference from other cells. In one design, a cell in the cluster may determine resources for sending a null pilot by the cell. The cell may transmit the null pilot (i.e., send no transmissions) on the resources to allow UEs to estimate out-of-cluster interference. Some or all cells in the cluster may transmit null pilots on the same resources. The cell may receive interference and channel information from the UE and may send data transmission to the UE based on the interference and/or channel information. Remaining cells in the cluster may reduce interference to the UE.

摘要： Techniques for managing interference in a wireless network are described. In an aspect, reduce interference requests and interference indicators may be used for interference management to enable operation in scenarios with dominant interferers. In one design, a terminal may receive a reduce interference request from a first base station requesting lower interference on specified time-frequency resources. The terminal may also receive an interference indicator conveying the interference observed by a second base station. The terminal may determine its transmit power based on the reduce interference request and the interference indicator. For example, the terminal may determine an initial transmit power based on the reduce interference request (or the interference indicator) and may adjust the initial transmit power based on the interference indicator (or the reduce interference request) to obtain its transmit power. The terminal may transmit data to a serving base station at the determined transmit power.

摘要： Techniques for selectively transmitting a power decision pilot are described. The power decision pilot may be indicative of the transmit power to use for data transmission in a future time interval. The power decision pilot may be transmitted when sufficiently beneficial for channel quality estimation or omitted otherwise. Whether or not to transmit the power decision pilot may be determined based on system type (e.g., heterogeneous or homogeneous system), the presence or absence of a dominant interferer, whether a reduce interference request is received, etc. For example, a base station may transmit a power decision pilot if it causes high interference to a non-served terminal, if a served terminal observes high interference from a neighbor base station, if the base station receives a reduce interference request from a non-served terminal, etc. The power decision pilot may be transmitted if a determination is made to transmit the pilot or omitted otherwise.

摘要： Providing for user equipment mobility in a multi-carrier wireless network deployment is described herein. By way of example, data pertinent to mobile cell selection can be shared among base stations operating on different carrier frequencies either over-the-air or via a wired backhaul, and distributed by a base station to mobile terminals served by the base station. In one aspect, the data can be distributed over a wireless channel reserved for inter-carrier association data, whereas in other aspects, the data can be unicast to particular mobile terminals served by the base station. This can reduce or avoid a need for individual mobile terminals to tune away to a non-serving carrier for inter-carrier association or handover determinations. Accordingly, gaps in signal analysis on a serving carrier can be reduced or avoided, improving overall quality of wireless communication in a multi -carrier environment.
摘要翻译：这里描述了在多载波无线网络部署中提供用户设备移动性。作为示例，与移动小区选择相关的数据可以在通过无线或经由有线回程在不同载波频率上工作的基站之间共享，并且由基站分配给由基站服务的移动终端。在一个方面，数据可以通过保留用于载波间关联数据的无线信道进行分配，而在其他方面，数据可以是单播到由基站服务的特定移动终端。这可以减少或避免各个移动终端调谐到非服务载波以进行载波间关联或切换确定的需要。因此，可以减少或避免在服务载体上的信号分析中的差距，提高多载波环境中的无线通信的整体质量。

摘要： Systems and methodologies are described that facilitate requesting blanking over control resources from one or more interfering eNBs or devices. An eNB, such as a macrocell, femtocell or picocell eNB, can transmit a downlink control blanking message to a UE directing the UE to perform blanking (e.g., for uplink control resources) or request the blanking from the interfering eNBs or devices (e.g., for downlink control resources). The downlink control blanking message can specify the desired control resources and/or information to determine the control resources. Thus, dynamic control blanking is provided such that blanking is requested to mitigate interference over control resources for the small scale eNB. The small scale eNB can subsequently communicate control data to the UE over the control resources; the control data can include a resource blanking message that similarly directs the UE to request blanking of general data resource from the interfering eNBs or devices.
摘要翻译：描述了有助于从一个或多个干扰eNB或设备请求对控制资源进行置空的系统和方法。诸如宏小区，毫微微小区或微微小区eNB的eNB可以向指示UE执行消隐（例如，对于上行链路控制资源）或从干扰eNB或设备请求消隐的UE发送下行链路控制置空消息（例如，用于下行链路控制资源）。下行链路控制消隐消息可以指定期望的控制资源和/或信息来确定控制资源。因此，提供动态控制消隐，使得消隐被请求以减轻针对小规模eNB的控制资源的干扰。小规模eNB随后可以通过控制资源向UE发送控制数据; 控制数据可以包括资源消隐消息，其类似地指示UE请求来自干扰eNB或设备的通用数据资源的消隐。

摘要： Techniques for supporting data transmission on the uplink in a wireless network are described. In an aspect, a user equipment (UE) may send a data transmission to a serving base station and may send uplink control information (UCI) to a non-serving base station. The UCI may include pertinent information to allow the non-serving base station to process the data transmission from the UE. In one design, the UCI may allow the non-serving base station to estimate the interference due to the data transmission from the UE and to cancel the interference at the non-serving base station. The interference cancellation may improve the received signal quality at the non-serving base station. After the interference cancellation, the non-serving base station may process a data transmission from another UE served by the base station.
