Abstract: A method for a wireless communication network is presented. In one embodiment, the method includes receiving, by a base station, information about one or more interfering base stations with respect to a communication channel used by a mobile station. The method includes sending silence requests to an interfering base station to reduce interference from that interfering base station with respect to the communication channel. The method further includes establishing communication with the mobile station via the communication channel.

Abstract: A station grouping mechanism has been presented for a wireless device that collects Multi-hop Relay Base Station (MR-BS) and Relay Stations (RSs) into groups according to their locations in a tree topology and assigns them with a phase. Grouping or partitioning MR-BS and RSs and assigning a distinct phase to the group prevent the MR-BS and the RSs from transmitting and receiving at the same time.

Abstract: Embodiments of a base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network are generally described herein. In some embodiments, a lower-tier base station is configured to adjust OFDMA frame boundaries to cause frames communicated by a higher-tier to arrive within a cyclic prefix at the lower-tier base station. The lower-tier base station may also be configured to adjust OFDMA frame boundaries to cause frames communicated by a lower-tier of the network to arrive within a cyclic prefix at a higher-tier mobile station. Accordingly, frames from one tier may arrive within the cyclic prefix of another thereby reducing asynchronous interference.

Abstract translation: 本文中一般地描述了用于减少多层OFDMA覆盖网络中的异步干扰的基站和方法的实施例。 在一些实施例中，低层基站被配置为调整OFDMA帧边界，以使由较高层传送的帧在低层基站处的循环前缀内到达。 低层基站还可以被配置为调整OFDMA帧边界，以使得由较低层网络传送的帧在较高层移动站处的循环前缀内到达。 因此，来自一个层的帧可以在另一层的循环前缀内到达，从而减少异步干扰。

Abstract: An interleaved frame structure provides the ability for access links and relay links to share a single channel and enable the transmission of packet information across a 2-hop path within one frame. The interleaved frame structure in combination with fast processing at the Relay Station (RS) allows scheduled packet information to travel from a Mobile Subscriber (MS) to its MR enabled base station (MR-BS) within one frame.

Abstract translation: 交织帧结构提供了访问链路和中继链路共享单个信道的能力，并使得能够在一帧内通过2跳路径传输分组信息。 交织帧结构与中继站（RS）上的快速处理相结合，允许调度的分组信息在一帧内从移动用户（MS）移动到其支持MR的基站（MR-BS）。

Abstract: Session continuity may be maintained when communication devices transition from communicating through network infrastructure (e.g., through a cellular network) to direct mode communications (e.g., a communication path directly between two communication devices). For example, in switching from an infrastructure mode communication path to a direct mode communication path, a method may include: determining a public-facing address corresponding to the infrastructure path; replacing, for a packet that is to be transmitted over the direct mode communication path to a second communication device, a source address field of the packet with the determined public-facing address; and encapsulating the packet with source and destination address fields corresponding to the first and second communication device through the direct mode communication path respectively.

Abstract translation: 当通信设备从通信网络基础设施（例如，通过蜂窝网络）转换到直接模式通信（例如，直接在两个通信设备之间的通信路径）时，可以维持会话连续性。 例如，在从基础设施模式通信路径切换到直接模式通信路径时，方法可以包括：确定与基础设施路径相对应的面向公众的地址; 将要通过直接模式通信路径发送的分组替换为具有确定的公共地址的分组的源地址字段; 并且通过分别通过直接模式通信路径封装与第一和第二通信设备相对应的源和目的地地址字段的分组。
