摘要： A method for self synchronization of a first base station is described. Synchronization information is received from a second base station. The first base station then synchronizes with the second base station using the received synchronization information. Synchronization information may be received from one or more base stations. The second base station may be part of the one or more base stations. A stratum may be determined for each of the one or more base stations. The synchronization information may include a stratum. The second base station may be selected as a synchronizing base station. The second base station may have the lowest stratum.

摘要： Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support transmission of control information on a first physical channel having a first minimum SNR for reliable reception. Some wireless devices may require operation at a lower SNR. In an aspect, low SNR operation may be supported by transmitting control information for a lower layer (e.g., Layer 1 or 2) in a protocol stack via an upper layer (e.g., Layer 3) in the protocol stack. This transmission scheme may allow the control information to be transmitted on a second physical channel instead of the first physical channel normally used to transmit the control information. The second physical channel may have a lower minimum SNR than the first minimum SNR. This transmission scheme may also allow the control information to be transmitted multiple times to improve reliability.

摘要： Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support a first physical channel having a first minimum SNR for reliable reception. Some wireless devices may require operation at a lower SNR. In an aspect, low SNR operation may be supported by transmitting data on a second physical channel that can be reliably received at a second minimum SNR that is lower than the first minimum SNR. In another aspect, low SNR operation may be supported by transmitting data on both the first and second physical channels. In yet another aspect, low SNR operation may be supported by transmitting data in multiple instances of the first and/or second physical channel. In yet another aspect, low power operation may be supported by transmitting the second physical channel in a portion of the system bandwidth instead of across the entire system bandwidth.

摘要： Systems and methodologies are described that facilitate transmitting pilot signals over resources selected based on a dynamic variable common to a wireless network. The resources can also be selected based on an identifier of a related access point to provide multiple levels of diversity in transmitting the pilot signal. Thus, a resource selected for a given access point can vary over subsequent frames and additionally vary with respect to other access points. A hash function can be utilized with the access point identifier to divide resources among access points, and using the dynamic variable, such as a frame identifier, can modify the selected resources over subsequent frames. This allows mobile devices to receive the pilot signals from access points at varying locations, for location determination in one example, with decreased interference.

摘要： Systems and methods that designate a control attachment point(s) during transmission of data in a Coordinated Multipoint (CoMP) system. The control attachment point is represented by an anchor cell to address control signaling and represent a User Equipment's (UE) interaction with the wireless communication system from a perspective of control (e.g., supplying/sending grants to the UE, transmitting/receiving ACKS on the downlink/uplink to the UE, control information (CQI), and the like.) The cells can further engage in backhaul transfer of information therebetween, and dynamic switching/change of anchor point based on criteria such as control loading, channel quality, and the like can further be implemented.

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： 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： Communication techniques enable efficient communication to UE (User Equipment) that is subject to a dominant interference signal that is transmitted by a different base station. Disclosed interference cancellation techniques, both UE-centric and network-centric, are suitable to this situation. These techniques are particularly advantageous when it is undesirable or difficult to introduce changes in the physical (PHY) and medium access control (MAC) layers at the existing base stations. An UE-centric framework refers to an approach largely implemented by UEs to include pico or femto cells. Network-centric framework closed-loop coordination between base stations and UEs achieves interference mitigation thereby improving network performance. In particular, an interfering base-station can help a "victim" UE by adjusting downlink pilot and control power and to adjust traffic data rates responsive to information that the "victim" UEs provide, including information about the interfering link and performance of the cancellation itself sent over the air or using backhaul.

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.
