    摘要： An apparatus, system, and method for space-time cochannel interference cancellation are described. The apparatus may include a time stacking module to stack consecutive subcarrier signals for a period of time equal to several symbols and a space-time subcarrier beamformer module to perform space-time subcarrier beamforming by applying space-time beamformer weights to stacked symbols on one or more subcarriers. The space-time beamformer weights may be calculated based on spatial and time correlation properties of one or more interference signals. Other embodiments are described and claimed.

    摘要： 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.
