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. In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier. 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 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).
摘要翻译：描述了在主要干扰场景中支持通信的技术。在一方面，可以通过跨子帧控制来支持主要干扰场景中的通信。可以为不同的基站分配不同的子帧以发送控制信息。每个基站可以在分配给该基站的子帧中发送控制消息。不同的基站可能具有不同的时间线，用于由于其不同的分配子帧而发送控制消息。利用跨子帧控制，可以在第一子帧中发送控制信息（例如，授权，确认等），并且可以适用于第二子帧中的数据传输，其可以是来自第一子帧的可变数量的子帧。在另一方面，可以在物理下行链路控制信道（PDCCH）上发送用于减轻干扰的消息。

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。在一方面，可以通过为较弱的基站预留来自强干扰基站的高干扰的较小的基站来支持主要干扰场景中的通信。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于来自第一站（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的冲突。在另一方面，中继器可以在其向宏基站监听的子帧中以及其向UE发送的子帧中的常规模式中以MBSFN模式进行发送。在另一方面，站可以传输比主要干扰源更多的TDM控制符号。

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.

摘要： Aspects are disclosed for multiplexing disparate wireless terminals. Resource blocks (640) are mapped according to a hopping pattern. A first and second pair of physical resource blocks are allocated such that the first pair is associated with a first hopping index pair, whereas the second pair is associated with a second hopping index pair. For this embodiment, the first and second hopping index pairs are inversely symmetrical to each other. A pair of distributed resource blocks is also allocated. An assignment is then scheduled that includes a physical resource allocation and a virtual resource allocation. Aspects for operating a wireless terminal are also disclosed. Here, a communication that includes a resource allocation and a reference signal is received. A minimum resource allocation granularity is ascertained from the communication, and a joint channel estimation is based on the reference signal and is a function of the minimum resource allocation granularity.

摘要： 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.
摘要翻译：描述了用于支持经由中继站的数据传输的技术。在一个方面，可以使用ACK和暂停来支持数据传输。发射机站向分组发送分组的第一个传输。发射机站不接收用于分组的第一次传输的ACK信息并暂停分组的传输。此后，发射机站接收到恢复分组传输的指示，并作为响应发送分组的第二次传输。另一方面，可应用不同的ACK时间线。接收机站可以在指定的子帧中发送ACK信息，如果可用或在不同的子帧中。在又一方面，可以使用ACK重复。当发射机站不能接收多个子帧中的一个或多个时，接收机可以在多个子帧中发送ACK信息以便于接收ACK信息。

摘要： To assist in minimizing interference, a bandwidth range can have guards on either side to reduce leakage into neighboring bandwidth ranges. However, in relatively low power situations the risk of leakage is reduced. Therefore, the guard bandwidths can be used to open new channels upon which information can be transmitted. Thus, there can be a larger amount of bandwidth used while still retaining protective aspects, such as low interference to neighboring bands. Using the guard bandwidth to transmit new channels facilitates backward compatibility since legacy devices do not commonly monitor the guard bandwidth. These techniques can also be used at high power base stations by advertising a larger guard than necessary to legacy devices and using the additionally created guard bandwidth to transmit new channels.
摘要翻译：为了帮助最小化干扰，带宽范围可以防止任何一方将泄漏减少到相邻的带宽范围。然而，在相对低功率的情况下，泄漏的风险降低。因此，保护带宽可以用于打开可以传输信息的新信道。因此，可以存在更大量的带宽，同时仍然保留保护方面，例如对相邻频带的低干扰。使用保护带宽传输新信道有助于向后兼容，因为传统设备通常不会监控保护带宽。这些技术也可以在高功率基站上使用，比传统设备所需的更大的卫星，并使用另外创建的保护带宽来传输新的信道。
