摘要： The invention provides solutions, including devices, systems, methods and software, for allowing interoperability between legacy stations and extended-range stations in a wireless network. Merely by way of example, an access point might be configured to transmit communications (such as beacon frames, broadcast frames, multi-cast frames, etc.) in a first mode and/or a second mode. The first mode might not employ extended-range technology, such that communications transmitted in the first mode can be received and/or interpreted by legacy stations, while the second mode might employ extended-range technology, such that communications transmitted in the second mode can be received by extended-range stations outside the range of basic-range communications. As another example, the access point might be configured to establish transmission “windows,” such that legacy stations are free to transmit during a first time period, in which extended-range stations are prohibited from transmission, followed by a second time period, in which extended-range stations are free to transmit, while transmission from legacy stations is prohibited.
摘要翻译：本发明提供了解决方案，包括设备，系统，方法和软件，用于允许无线网络中的传统站和扩展站之间的互操作性。仅仅作为示例，接入点可以被配置为在第一模式和/或第二模式中发送通信（诸如信标帧，广播帧，多播帧等）。第一模式可能不采用扩展范围技术，使得以第一模式发送的通信可以由传统站接收和/或解释，而第二模式可以采用扩展范围技术，使得以第二模式发送的通信可以由基站范围以外的扩展站接收。作为另一示例，接入点可以被配置为建立传输“窗口”，使得传统站可以在第一时间段内自由传输，其中扩展范围站被禁止传输，随后是第二时间段哪些扩展站可以自由传输，而传统站点的传输是禁止的。

摘要： Circuits, methods, and apparatus that reduce overhead and channel bandwidth required for data reception acknowledgment. One such system uses an enhanced block acknowledgment that acknowledges frames received for different data streams. Another system sends an acknowledgment after the occurrence of a triggering event, such as the end of a duration, the reception of a number of frames, or the reception of a frame having a specific sequence number. Another removes the need for acknowledgment frames by including an acknowledgment field in a transmitted data frame. These block acknowledgments and acknowledgment fields may include an acknowledgement of frames received for each data stream having different traffic identifications, they may be for all received frames or for a specific class or groups of classes of traffic, for specific user priorities, or for other subgroups of received frames, and more that one acknowledgment may be included.

摘要： In a wireless network according to embodiments of the present invention, fast control messaging frames are used to signal control information. A fast control messaging (“FCM”) frame includes MAC layer control bits in a PLCP header, obviating the need for a PSDU. These frames can be used in 802.11n wireless networks as well as in other suitable 802.11x networks as well as non-802.11x networks to exchange control information while significantly reducing network overhead. In some embodiments, some information that might have been conveyed to a receiver's MAC layer in a PSDU is conveyed by including that information is a PLCP header and having logic within the receiver's PHY layer processing to process that information and convey that information up to the receiver's MAC layer in a simulated PSDU or other method. The indicator of an FCM frame can be a bit in a PLCP header, a modification of a CRC field of the PLCP header, or other indicator. The medication of the CRC field of the PLCP header can be an inversion of the CRC field, a translation of the CRC field by a constant value, or both, or some other variation.

摘要： Circuits, methods, and apparatus that provide high-throughput control fields that, among other functions, provide efficient TXOP handoffs in wireless networks. A handoff may be made by setting one or more bits in a field in a QoS frame, such as the HT control or other appropriate field. Various conditions may be placed on a handoff by a granting station. For example, conditions specifying where a station receiving a TXOP handoff may send data, what the receiving station may do with any remaining TXOP, or what types of data may be transmitted by the receiving station may be imposed. These various conditions may be combined or omitted in any logic combination.

摘要： To detect the number of transmit antennas, a fast Fourier transform operation is performed on the received samples of the transmitted long training symbols of a preamble. Next, each of the Fourier transformed results is multiplied with the reference frequency-domain representation of the long training symbol so as to remove the effect of the symbols and to maintain the channel information. Next, inverse Fourier transform or least squares operations is performed on the multiplied values to compute channel impulse response. The number of shifted impulse response in the channel impulse response represents the detected number of transmit antennas. Packets containing preambles of the present invention may be received by extended devices as well as by legacy receivers that are not configured to receive and interpret these preambles. The training symbols may be cyclically-shifted and transmitted on different transmit antennas.

摘要： A modified preamble is used by extended devices that operate in mixed mode environments and green field environments, to accommodate beamforming of transmissions. In one process, an extended wireless device processes data for transmission of that data as a packet, wherein the extended wireless device is a device configured to communicate using a standard protocol understood by each node device and an extended protocol not understood by legacy node devices. If the packet is to be directed at an extended device, the extended wireless device sends a preamble of that packet that is usable in an extended mode at extended devices and usable at a receiving legacy device to determine that the receiving legacy device is not the destination of data to follow the preamble. Once the receiving legacy device is expected to be deferring the network, the extended wireless device can beamform its signal or otherwise vary from the legacy protocol in communications with extended devices.

摘要： Systems and methods for wide frequency offset synchronization are provided. A synchronization data sequence is encoded onto a series of OFDM frequency domain bursts as interburst phase differences between training symbols included within the successive bursts. The interburst phase differences may also encode system configuration information. This technique may be used in conjunction with other synchronization techniques to greatly extend the frequency acquisition range achievable with low cost analog components.

摘要： A space-time signal processing system with advantageously reduced complexity. The system may take advantage of multiple transmitter antenna elements and/or multiple receiver antenna elements, or multiple polarizations of a single transmitter antenna element and/or single receiver antenna element. The system is not restricted to wireless contexts and may exploit any channel having multiple inputs or multiple outputs and certain other characteristics. Multi-path effects in a transmission medium cause a multiplicative increase in capacity.
