摘要： Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with time division multiplex (TDM) partitioning of downlink control resources. For TDM partitioning, different base stations may be allocated different time resources. Each base station may send its control information in its allocated time resources and may avoid sending control information (or may send control information at a lower transmit power level) in time resources allocated to other base stations. In another aspect, communication in a dominant interference scenario may be supported with frequency division multiplex (FDM) partitioning of uplink control resources. For FDM partitioning, different base stations may be allocated different frequency resources. In one design, TDM partitioning may be used for downlink control resources, and FDM partitioning may be used for uplink control resources.

摘要： Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with cross-subframe control. Different base stations may be allocated different subframes for sending control information. Each base station may send control messages in the subframes allocated to that base station. Different base stations may have different timelines for sending control messages due to their different allocated subframes. With cross-subframe control, control information (e.g., grants, acknowledgement, etc.) may be sent in a first subframe and may be applicable for data transmission in a second subframe, which may be a variable number of subframes from the first subframe. In another aspect, messages to mitigate interference may be sent on a physical downlink control channel (PDCCH).

摘要： Systems and methodologies are described that facilitate improved resource partitioning and interference management in a wireless communication system. Techniques are described herein for the transmission and use of various types of signaling, such as Access Request commands, Reverse Link Special Resource Utilization Message (R-SRUM) signaling, Forward Link Special Resource Utilization Message (F-SRUM) signaling, and the like, for managing interference associated with range extension, restricted association networks, and other jamming scenarios. As described herein, downlink resource coordination and interference management are accomplished through the use of Access Request or R-SRUM signaling conducted in a unicast or broadcast fashion, and uplink resource coordination and interference management are accomplished through the use of F-SRUM signaling. As further described herein, a clean communication channel such as a Low Reuse Preamble (LRP) channel can be utilized for interference management signaling and/or leveraged for determining timing of various signaling messages.

In one example, a repeater using orthogonal frequency division multiplexing on the downlink can be equipped to receive, by one or more receive antennas, one or more signals using one or more radio frequency (RF) isolation schemes. The repeater can further be equipped to amplify and delay the one or more signals using one or more combination schemes. Moreover, the repeater can be equipped to transmit, by one or more transmit antennas, the amplified and delayed one or more signals, wherein at least one of the one or more receive antennas or the one or more transmit antennas includes two or more antennas.

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UEs may use the bitmap to control their operation. For example, a UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. In another aspect, a base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UEs communicating with the relay station.
摘要翻译：描述了用于支持无线通信系统中的中继站操作的技术。在一个方面，可以由基站和/或中继站发送位图以识别多个无线电帧中的至少两种类型的子帧。例如，位图可以指示位图覆盖的每个子帧是第一类型还是第二类型。 UE可以使用该位图来控制其操作。例如，UE可以针对第一类型的子帧执行信道估计或测量，并且可以跳过针对第二类型的子帧的信道估计和测量。另一方面，基站可以在没有被中继站用来传输参考信号的资源上传输数据和/或控制信息。这可以避免对来自中继站的参考信号的干扰，这可以提高与中继站通信的UE的性能。

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a base station may transmit data to a relay station in a portion of a subframe instead of the entire subframe. The relay station may transmit control information during part of the subframe. The base station may transmit data to the relay station during the remaining part of the subframe. In another aspect, a target termination for a packet may be selected based on data and/or ACK transmission opportunities available for the packet. One or more transmissions of the packet may be sent with HARQ, and ACK information may be sent for the packet. The packet may be transmitted such that it can be terminated prior to the first subframe (i) not available for sending the packet or (ii) available for sending ACK information.

摘要： Techniques for sending signaling messages with beacon signals in a wireless communication network are described. In one design, a transmitter station may map a signaling message (e.g., a reduce interference request) to multiple code symbols. The transmitter station may select multiple resource elements from among a plurality of resource elements based on the multiple code symbols. In one design, each code symbol may be sent across frequency by selecting one of multiple subcarriers in one symbol period (500). In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier (700). The transmitter station may generate a beacon signal having transmit power on the selected resource elements and no transmit power on remaining resource elements. The transmitter station may send the beacon signal to at least one receiver station.

摘要： Techniques for transmitting overload indicators over the air to UEs in neighbor cells are described. In one design, an overload indicator may be transmitted as a phase difference between at least one synchronization signal and a reference signal for a cell. In another design, an overload indicator may be transmitted as a phase difference between consecutive transmissions of at least one synchronization signal for a cell. In yet another design, an overload indicator may be transmitted by a cell on resources reserved for transmitting the overload indicator. In yet another design, an overload indicator may be transmitted by a cell on a low reuse channel or a broadcast channel. For all designs, a UE may receive overload indicators from neighbor cells, determine the loading of each neighbor cell based on the overload indicator for that cell, and control its operation based on the loading of the neighbor cells.

摘要： Techniques for supporting communication in a heterogeneous network are described. In an aspect, communication in a dominant interference scenario may be supported by reserving subframes for a weaker base station observing high interference from a strong interfering base station. In another aspect, interference due to a first reference signal from a first station (e.g., a base station) may be mitigated by canceling the interference at a second station (e.g., a UE) or by selecting different resources for sending a second reference signal by the second station (e.g., another base station) to avoid collision with the first reference signal. In yet another aspect, a relay may transmit in an MBSFN mode in subframes that it listens to a macro base station and in a regular mode in subframes that it transmits to UEs. In yet another aspect, a station may transmit more TDM control symbols than a dominant interferer.
摘要翻译：描述了用于支持异构网络中的通信的技术。在一个方面，可以通过保留用于观察来自强干扰基站的高干扰的较弱基站的子帧来支持主导干扰场景中的通信。在另一方面，可以通过消除第二站（例如，UE）处的干扰或通过选择用于发送第二参考信号的不同资源来减轻由来自第一站（例如，基站）的第一参考信号引起的干扰由第二站（例如，另一个基站）避免与第一参考信号冲突。在又一个方面中，中继站可以在MBSFN模式中在其监听宏基站的子帧中以及在其发送给UE的子帧中以常规模式进行传送。在又一方面，站点可以传输比主要干扰源更多的TDM控制符号。
