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： 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： 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： First technique (fig. 5) : a signalling message, e.g., a reduce interference request is sent by mapping it to at least one specific subcarrier (m) among a set of subcarriers reserved for sending the signalling message (0, 1, 2,..., m,..., M-1). The at least one subcarrier is selected based on the message value. A signal is then sent on the at least one subcarrier (m) in multiple symbol periods to convey the signalling message. Second technique (fig. 6) : a reduce interference request is sent by mapping it into an orthogonal sequence {u?, ul,..., uM-1} of length M, among a set of M orthogonal sequences. The sequence is selected based on the message value. The sequence is sent on a resource segment, formed by T symbol periods and N subcarriers, wherein T*N=M. Third technique (fig. 7) : a reduce interference request is processed to obtain modulation symbols, and each modulation symbol is then spread, by means of a known reference signal sequence r(n), across multiple subcarriers in one symbol period.

摘要： Systems and methodologies are described herein that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system. As described herein, a network device can measure and report interference corresponding to network nodes outside a designated set of nodes that can cooperatively serve the device. Respective interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of respective nodes, or the like. Subsequently, respective interference reports can be combined with per-node channel information to manage coordination and scheduling across respective network nodes. As further described herein, interference from a network node can be measured by observing reference and/or synchronization signals from the network node. To aid such observation, respective non-interfering network nodes can define null pilot intervals in which transmission is silenced or otherwise reduced. As additionally described herein, loading information broadcasted by respective interfering network nodes can be identified and utilized in connection with interference calculation.

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.

摘要： In a wireless communication system, short-term interference mitigation may be used to mitigate (e.g., to avoid or reduce) interference on a given link in order to improve performance of data transmission. The interference mitigation reduces transmit power of interfering transmissions so that a higher signal-to-noise-and-interference ratio (SINR) can be achieved for a desired data transmission. A node may observe high interference from an interfering node that degrades performance of data transmission sent on that link. By taking advantage of an communication path with the interfering node (e.g., wireless data/control channel, backhaul network connection, or analog broadcast signal), the transmitting node can successfully complete time critical communications while allowing the interfering node to also simultaneously communicate without reducing overall resources nor burdening any managing nodes.
摘要翻译：在无线通信系统中，可以使用短期干扰减轻来减轻（例如，以避免或减少）给定链路上的干扰，以便提高数据传输的性能。干扰减轻降低干扰传输的发射功率，从而可以实现更高的信噪比干扰比（SINR），用于所需的数据传输。节点可能会观察到来自干扰节点的高干扰，从而降低在该链路上发送的数据传输的性能。通过利用与干扰节点（例如，无线数据/控制信道，回程网络连接或模拟广播信号）的通信路径，发送节点可以成功地完成时间关键通信，同时允许干扰节点同时通信而不减少整体资源也不负责管理节点。

摘要： Systems and methodologies are described herein that facilitate generation and processing of control signaling to support uplink network multiple-in-multiple-out (N-MIMO) communication in a wireless communication system. As described herein, respective network nodes associated with an uplink N-MIMO framework can generate channel state information (CSI) corresponding to an uplink channel from a designated network user to the respective nodes. Generated CSI can subsequently be communicated to an uplink anchor node for the network user in order to facilitate rate assignment, scheduling, and/or other operations with respect to the network user. As described herein, CSI generated and reported by respective cells can include channel profiles, carrier/interference profiles, estimated supported uplink rates, or the like. As additionally described herein, supplemental information such as observed interference levels, demodulation indicators, or the like can be communicated to an anchor node and utilized in rate assignment and/or scheduling.
