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： 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，中继器可以以MBSFN模式在其向宏基站收听的子帧中以及在向UE发送的子帧中以常规模式进行发送。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： Techniques for supporting communication in a dominant interference scenario are described. A user equipment (UE) may communicate with a first base station and may observe high interference from and/or may cause high interference to a second base station. In one design, the first base station may use a first frequency band, which may overlap at least partially with a second frequency band for the second base station and may further extend beyond the second frequency band. The first base station may send at least one synchronization signal and a broadcast channel in a center portion of the first frequency band for use by UEs to detect the first base station. The second frequency band may be non-overlapping with the center portion of the first frequency band. The first base station may also communicate with at least one UE on the first frequency band.

摘要： Techniques for mitigating data loss during autonomous system information (SI) reading by a user equipment (UE) are described. For autonomous SI reading, the UE may autonomously determine when to read system information from neighbor cells and may not inform a serving cell. In one design, the UE may autonomously select a SI reading gap for reading system information from a neighbor cell. During the SI reading gap, the UE may suspend reception of downlink transmission from the serving cell, receive system information from the neighbor cell, and maintain capability to transmit on the uplink to the serving cell. In one design, the serving cell may determine SI reading gaps autonomously selected by the UE for reading system information from neighbor cells. The serving cell may communicate with the UE by accounting for the SI reading gaps of the UE, e.g., may suspend communication with the UE during the SI reading gaps.

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： 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.
