Abstract: A method and wireless device merge multiple unsynchronized beacon groups in a wireless network, each beacon group including at least one wireless device. A first beacon is received from at least one first wireless device in a first beacon group (S514), the first wireless device having a first directional antenna. A second beacon is received from at least one second wireless device in a second beacon group that is not synchronized with the first beacon group (S516), the second wireless device having a second directional antenna. A first response beacon is relocated (S520) and sent (S522) to the first wireless device in the first beacon group. The relocated first response beacon instructs the first wireless device to relocate the first beacon. Accordingly, the second beacon, the relocated first response beacon, and the relocated first beacon are synchronized.

Abstract: The application describes a method to merge two wireless networks in which each terminal gets a beacon slot within the beacon period. In order to merge two networks, the beacon slots have to be time-coordinated such that the beacon slots of the first network are completed before the beacon slots of the second network begin. The method includes transmitting a beacon frame having a beacon period switch information element which instructs the neighboring terminals in the first network of the need to merge, provides clock synchronization information; provides the time of the merge; and informs the neighboring terminals which beacon slot to occupy in the beacon period of the merged network. In order to deal with hidden terminals, the information needs to be forwarded terminal-to-terminal within each network.

Abstract: A wireless device (100) communicates in a wireless system by selecting a communication channel (202) for communication, identifying a control channel or control channels (204) designated for communication of control information for the selected communication channel, and listening for the control information (212) on the control channel to determine if the selected communication channel is bonded with any other communication channel. When control information is received via the control channel(s) indicating that the selected communication channel is bonded with at least one other communication channel, then the wireless device abstains from communication on the selected communication channel, or communicates in a narrowband mode. When control information is received via the control channel(s) indicating that the selected communication channel is not bonded with another communication channel, or when no control information is received via the control channel, then the wireless device communicates via the selected communication channel.

Abstract: The present invention provides a system (600), device (500) and method (400) for automatic partner selection in an existing Cooperative MAC (CMAC) protocol, which uses the Ready-to-Send (RTS), Clear-to-Send (CTS) and Partner-Clear-to-Send (PCTS) handshaking to establish cooperation. The present invention enables a “best” partner/relay (500.R.k) who is also willing to cooperate to relay information to a destination (500.D.J) for the transmitting device (i.e., the source), without the source (500.S.i) making a decision on partner selection. That is, the present invention provides a new mechanism by which the best partner/relay (500.R.k) that is also willing to cooperate will “step in” automatically without the source's involvement in selection of the partner/relay (500.R.k). This mechanism is contention-based and the partner is “selected” using local information only in a fully distributed manner.

Abstract translation: 本发明提供了一种用于在现有协作MAC（CMAC）协议中自动配对选择的系统（600），设备（500）和方法（400），其使用即时发送（RTS），清除发送 （CTS）和Partner-Clear-to-Send（PCTS）握手建立合作关系。 本发明使得也能够合作的“最佳”伙伴/中继（500.RK）能够将信息中继到用于发送设备（即，源）的目的地（500.DJ），而不需要源（500.RJ）。 Si）决定合作伙伴选择。 也就是说，本发明提供了一种新机制，通过该机制，也愿意协作的最佳伙伴/中继（500.RK）将自动“进入”，而不需要参与选择对方/中继（500.RK） 。 这种机制是基于争用的，合作伙伴只能以完全分布的方式“使用本地信息”进行选择。

Abstract: The current MBOA UWB MAC protocol requires a device that detects alien devices to include a BP Switch IE in its beacon so that its neighbors may learn the presence of the alien devices and follow that device to relocate their beacons in a coordinated fashion. However, during the transition period of beacon relocation, that device may decide to halt the relocation process as required by the standard and such decisions also have to be received by its neighbors. In such a case, a BP switch IE will be generated by that device which includes a BPST offset equal to a length of a superframe.

Abstract translation: 目前的MBOA UWB MAC协议需要一种能够检测外来设备在其信标中包含BP交换机IE的设备，以便其邻居可以学习外来设备的存在并跟随该设备以协调的方式重新定位其信标。 然而，在信标重定位的过渡期间，该设备可以根据标准的要求决定停止重定位过程，并且这样的决定也必须由其邻居接收。 在这种情况下，BP开关IE将由该设备生成，该设备包括等于超帧长度的BPST偏移量。

Abstract: A Single Carrier Block Transmission (SCBT) system employs an inherently parallel approach to error correction processing. At the transmission system (200), an incoming data stream is split (210) into P parallel data streams, each having a data rate equal to a fraction of the incoming data stream's data rate. The parallel data streams are then each separately encoded (220) in P parallel encoding processes (beneficially, using P parallel encoders (222)). The P separately encoded data streams are then merged (330), interleaved (320), and mapped (310) into a single stream of encoded symbols, which are transmitted to the receiver using an arbitrary modulation (240) and transmission scheme. At the receiver (255), the received data stream is de-interleaved (350) and split into P encoded data streams, which are then decoded (285) using P parallel decoders. Then, the decoded data streams are combined or multiplexed (295) into a single data stream.

Abstract translation: 单载波块传输（SCBT）系统采用固有的并行方法进行纠错处理。 在传输系统（200）处，输入数据流被分离（210）为P个并行数据流，每个数据流的数据速率等于输入数据流的数据速率的一小部分。 然后，并行数据流在P个并行编码处理（有利地，使用P个并行编码器（222））中分别编码（220）。 然后将P个分离编码的数据流合并（330），交织（320）和映射（310）到编码符号​​的单个流中，其使用任意调制（240）和传输方案发送到接收机。 在接收机（255）处，对接收到的数据流进行解交织（350）并分割成P个编码数据流，然后使用P个并行解码器解码（285）。 然后，解码的数据流被组合或多路复用（295）到单个数据流中。
