    • 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.
    • 描述了有助于在无线通信环境中向目标服务基站指示显着干扰的系统和方法。 移动设备可以检测是否存在主要干扰源。 此外,可以生成包括与主要干扰源的存在或不存在有关的信息的接入探测。 例如,可以将信息作为显式标志,干扰水平的明确指示,信道质量指示符(CQI)值(例如,保留与非保留,...)一起包括在接入探测的有效载荷中, 等等。而且,接入探测可以被发送到目标服务基站以发起接入过程。 目标服务基站可以根据包括在接入探测中的信息来选择要用于响应下行链路传输(例如,接入准许信号,后续接入相关消息,...)的时间 - 频率资源。

    • 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.
    • 描述了用于选择性地发送功率决策导频的技术。 功率决策导频可以指示在未来的时间间隔内用于数据传输的传输功率。 功率决定导频可以在对信道质量估计充分有利时发送,否则将被忽略。 可以基于系统类型(例如,异构或同构系统),是否存在主要干扰源,是否接收到降低干扰请求等来确定是否发送功率决策导频。例如,基站 如果服务终端观察到来自相邻基站的高干扰,如果基站接收到来自非服务终端的减少干扰请求等,则可以传送功率决策导频,如果它对非服务终端造成高干扰的话。 如果做出发送导频的确定或者否则忽略,则可以发送功率决定导频。

    • 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.
    • 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。

    • Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.
    • 描述了通过中继站支持数据传输的技术。 在一方面,可以使用ACK和挂起来支持数据传输。 发送站发送分组的第一次发送到接收站。 发送台不接收用于分组的第一次发送的ACK信息,并且暂停分组的发送。 然后,发送站接收到恢复分组的发送的指示,并且作为响应,发送分组的第二发送。 在另一方面,当适用时可以使用不同的ACK时间线。 如果可以使用或在不同的子帧中,则接收站可以在指定的子帧中发送ACK信息。 在另一方面,可以使用ACK重复。 接收机可以在多个子帧中发送ACK信息,以便当发射机站不能接收多个子帧中的一个或多个时,接收ACK信息。

    • Methods, apparatuses, and computer program products are disclosed for encoding/decoding a wireless control signal. For encoding, control bits are received and encoded with a first error control code so as to create a first set of encoded bits. The encoded bits are then encoded with a second error control code so as to create a second set of encoded bits, which are modulated as beacon tones and subsequently transmitted. For decoding, beacon tones corresponding to a set of control bits are received and subsequently demodulated so as to ascertain a set of demodulated bits. The demodulated bits are then decoded with a decoder so as to ascertain a set of decoded bits. The decoded bits are then decoded with a second decoder so as to ascertain a second set of decoded bits, which includes the set of control bits.
