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： 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： Systems and methodologies are described that facilitate assigning uplink resources for utilization by a mobile device for sending an uplink signal in an uplink coordinated multi-point (CoMP) wireless communication environment. For instance, a hopping tree can be defined across base stations, and neighboring base stations can schedule interfering mobile devices upon uplink resources mapped to different nodes from the hopping tree. By way of another example, a plurality of hopping trees can be employed across base stations in the uplink CoMP wireless communication environment. Moreover, an acknowledgment can be sent to the mobile device upon downlink resources identified as a function of the uplink resources. Further, the downlink resources can be distinct from disparate downlink resources utilized for sending an acknowledgment to a disparate mobile device from a neighboring base station.

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： 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 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.

摘要： Techniques for transmitting and receiving data with spatial interference mitigation in a wireless communication network are described. In one design, a cell may receive precoding information from a first user equipment (UE) communicating with the cell and spatial feedback information (SFI) from a second UE not communicating with the cell. The cell may select a precoding matrix based on the precoding information and the SFI. The precoding matrix may steer a transmission toward the first UE and away from the second UE. The cell may send a reference signal based on the precoding matrix, send a resource quality information (RQI) request to the first UE, receive RQI determined by the first UE based on the reference signal, and determine a modulation and coding scheme (MCS) based on the RQI. The cell may then send a data transmission to the first UE with the precoding matrix and in accordance with the MCS.
