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: A protocol framework for MS handover in MR networks includes new messages and an optimized flow of these messages. A framework for use in a multi-hop topology of MR networks optimizes the handover performance. The framework is applicable and expandable to the design of a new control message exchange procedure for MS handover.

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.
