    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: 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: A method for forming a transparent conductive film by atomic layer deposition includes providing more than one kind of oxide precursor which is individually introduced into atomic layer deposition equipment through different sources, wherein the oxide precursors are consecutively introduced into the atomic layer deposition equipment at the same time, so that the oxide precursors are simultaneously present in the atomic layer deposition equipment, to form a uniform mixture of oxide precursors in a single adsorbate layer for settling onto a substrate in the atomic layer deposition equipment. Then, an oxidant is provided to react with the oxide precursors to form a single multi-oxide atomic layer. The above mentioned steps are repeated to form a plurality of multi-oxide atomic layers.

    Abstract: A wireless device (200, 310-1) executes a method (400) of reserving a time slot for communication with a second wireless device (200, 310-4) in a communication network 5 (300). The wireless device (200, 310-1) determines whether any antenna beam to be used in a proposed communication with the second wireless device (200, 310-4) communication within the time slot would interfere with any antenna beam used by any first wireless device (200, 310-i) in any existing reservations for the time slot. When any antenna beam to be used in the proposed communication would not interfere with any antenna beam used 10 by any first wireless device (200, 310-i) in any existing reservations for the time slot, the wireless device (200, 310-1) transmits an information element (500) or reserving the time slot for communication with the second wireless device (200, 310-4).

    Abstract: Wireless stations (108-1-108-N) contending for exclusive access for a predetermined period of time (S232) to transmit on a communication medium (112) are regulated by a common external controller (104) using a single timing parameter (S204). Attempts at transmission access are preceded by respective delays that are expired simultaneously and at a common rate by the stations at times when the stations sense the medium to be idle (S224). The delays are pseudo-randomly selected to avoid collisions among stations in their respective access attempts (S208). Default, initial values of the respective delays (S204) applied to the stations, when multiplied by the respective expected number of transmission attempts by the stations over the long term over periods of time when no transmission attempt is unsuccessful, yield respective products equal to a constant value common to all stations (S312). The default values therefore serve as a knob by which the controller regulates air time opportunity.
