    Abstract: Communication signals using a first and a second frequency band in a wireless network is described herein. The first frequency band may be associated with a first beamwidth while the second frequency band may be associated with a second beamwidth, the first beamwidth being wider than the second beamwidth. The first frequency band may be used to communicate first signals to facilitate initial communication, including signals and/or control information to coarsely configure a receiving device. The second frequency band may then be used to communicate second signals that facilitate further communication, including signals and/or control information for finer configuring of the receiving device. Alternatively, the first and second frequency bands may be used in a wireless network to communicate a first and a second signals independently.

    Abstract: In an orthogonal frequency division multiplexed (OFDM) system, a transmitter and/or receiver communicate separate data streams on non-orthogonal spatial channels. Each spatial channel may use the same set of OFDM subcarriers and may take advantage of the multipath characteristics of the spatial channel allowing the communication of additional data without an increase in frequency bandwidth. Space-frequency subcarrier modulation assignments may be dynamically assigned on a per subcarrier basis as well as a per spatial channel basis to help maximize the data-carrying capacity of the channel. In some embodiments, each of the spatial channels may be associated with one of a plurality of spatially diverse antennas. In other embodiments, beamforming may be performed to allow the transmission and/or reception of signals within the spatial channels.

    Abstract: A frame format provides for wideband wireless local area network communications and informs narrower-band communication units when the channels are occupied by wider-band communication units. In some embodiments, the frame format includes a channelization field identifying channels that are used for communicating subsequent wideband fields of a packet, and a wideband-header field communicated on the identified channels. The wideband-header field may identify sub-fields that may be present in the wideband-header field, and may identify the presence of a wideband-data field. A long-compatibility field may be present that provides protection at the MAC level. The long-compatibility field may transport MAC frames that may include medium-reservation information compatible with narrower-band communication units.

    Abstract translation: 帧格式提供宽带无线局域网通信，并且当信道被更宽带通信单元占用时通知窄带通信单元。 在一些实施例中，帧格式包括识别用于传送分组的后续宽带字段的信道的信道化字段以及在所识别的信道上传送的宽带报头字段。 宽带报头字段可以标识可能存在于宽带报头字段中的子字段，并且可以识别宽带数据字段的存在。 可能存在在MAC级提供保护的长兼容性字段。 长兼容性字段可以传送可能包括与窄带通信单元兼容的媒体预留信息的MAC帧。
