摘要： Aspects of the present invention provide additional MAC functionality to support the PHY features of a wireless communication system framework. The additional MAC functionality aids in enabling feedback from wireless terminals to base stations. In some aspects of the invention the feedback is provided on an allocated feedback channel. In other aspects of the invention the feedback is provided by MAC protocol data units (PDU) in a header, mini-header, or subheader. The feedback may be transmitted from the wireless terminal to the base station autonomously by the wireless terminal or in response to an indication from the base station that feedback is requested. Aspects of the invention also provide for allocating feedback resources to form a dedicated feedback channel. One or more of these enhancements is included in a given implementation. Base stations and wireless terminals are also described upon which methods described herein can be implemented.

摘要： This disclosure describes equalization techniques for spread spectrum wireless communication. The techniques may involve estimating a channel impulse response, estimating channel variance, and selecting filter coefficients for an equalizer based on the estimated channel impulse response and the estimated channel variance. Moreover, in accordance with this disclosure, the channel variance estimation involves estimation of two or more co-variances for different received samples. Importantly, the equalizer is “fractionally spaced,” which means that the equalizer defines fractional filtering coefficients (filter taps), unlike conventional equalizers that presume that filter coefficients are defined at integer chip spacing. The techniques can allow the equalizer to account for antenna diversity, such as receive diversity, transmit diversity, or possibly both.
摘要翻译：本公开描述了用于扩频无线通信的均衡技术。这些技术可以包括基于所估计的信道脉冲响应和所估计的信道方差估计信道脉冲响应，估计信道方差，以及为均衡器选择滤波器系数。此外，根据本公开，信道方差估计涉及对于不同接收样本的两个或多个协方差的估计。重要的是，均衡器是“分数间隔”的，这意味着均衡器定义了分数滤波系数（滤波器抽头），不同于传统的均衡器，假设滤波器系数是以整数芯片间隔定义的。这些技术可以允许均衡器考虑天线分集，例如接收分集，发射分集，或者可能两者。
