摘要： Enhanced frame preambles facilitate co-channel co-existence in a wireless communication environment by having at least one preamble characteristic that connotes channel-sharing information regarding the wireless communication environment. In an exemplary embodiment, a downlink subframe is received in one or more wireless communication signals in a wireless communication environment. A preamble is detected in the downlink subframe, and at least one characteristic of the preamble is ascertained. Channel-sharing information for the wireless communication environment is determined based upon the at least one characteristic of the preamble. In another exemplary embodiment, a channel is scanned to detect secondary preambles being transmitted on the channel. A current preamble configuration, including a permutation of preamble location and preamble content corresponding to the secondary preambles, is determined, which connote channel-sharing information. A next available preamble location may be adopted based on the current preamble configuration.

摘要： Explicit feedback format within single user, multiple user, multiple access, and/or MIMO wireless communications. A beamformer provides a first communication to a beamformee, and based thereon, the beamformee may ascertain certain characteristics associated with the type and format of feedback to be provided to the beamformee via a second communication from the beamformee to the beamformer. For example, the first communication may include indication of a current operational mode, such as whether it is in accordance with single-user multiple input multiple output (SU-MIMO) or multi-user multiple-input-multiple-output (MU-MIMO). Also, the first communication may indicate a requested steering matrix's rank to be employed in accordance with subsequent beamforming by the beamformer. Also, additional information such as that pertaining to per-tone SNR values for each respective space-time stream, per-tone or per-sub-band eigen-values, the particular channel width being employed (e.g., 20, 40, 80, or 160 MHz), etc. may be included within the second communication.

摘要： In a communication network, a sending node transmits a message with a multi-segment preamble and data to a receiving node. The receiving node calculates characteristics of the sending unit, channel, or transmitted signal by processing preamble segments. Once an unknown characteristic is determined, a segment of the preamble can be eliminated or reduced in length for subsequent messages, which increases efficiency of the message transmissions.

摘要： Channel state information in a closed-loop, multiple-input, multiple-output wireless networks is fed back from each mobile station to a base station by first determining a transmit covariance matrix R, and applying a singular value decomposition (SVD) R=UΣVH, where U, V are left and right singular vector matrices, Σ is a diagonal matrix with singular values. The matrix V includes column vectors V. A beamforming vector vmax=[1 exp(jΦ)exp(j2Φ) . . . exp(jΦ)]/√{square root over (N)}] is approximated by the column vector V having a maximum magnitude, where Φ is a real number. Then, only the angle Φ is fed back using a phase modulation mapping of the components exp(jΦ) onto the associated subcarrier.

摘要： A base station (BTS) may instruct a client station (CS) to transmit sounding signals that the BTS may analyze to determine what adjustments, such as power, time, and/or frequency adjustment(s) should be made by the CS. The BTS may control when and how the sounding signals are sent by the CS. This helps reduce the possibility of adjustment signals transmitted by two or more CSs colliding. Thus, sounding signals transmitted by the CS in response to a request by the BTS can be received by the BTS with higher a probability of success. This permits the BTS to more accurately characterize the channel and to provide better adjustment of power level, frequency offset, and/or timing offset for more optimal communication. Such techniques can be used to reduce bit error rates and to improve the overall signal to noise ratio encountered by the system.
摘要翻译：基站（BTS）可以指示客户站（CS）发送BTS可以分析的探测信号，以确定CS应该进行哪些调整，诸如功率，时间和/或频率调整。 BTS可以控制CS的发送信号的时间和方式。这有助于减少由两个或多个CS发生的调整信号的碰撞的可能性。因此，响应于BTS的请求，由CS发送的探测信号可以由BTS以更高的成功概率接收。这允许BTS更准确地表征信道，并且为了更优化的通信而提供功率电平，频率偏移和/或定时偏移的更好的调整。这样的技术可以用于降低误码率并提高系统遇到的整体信噪比。

摘要： Long training field (LTF) for use within single user, multiple user, multiple access, and/or MIMO wireless communications. Classification of a signal may be performed using one or more LTF's therein. While such one or more LTF's may also be employed for performing functions such as channel estimation, channel characterization, etc., one or more particular characteristics of an LTF extracted from a received signal may also be employed to classify the signal as corresponding to one of a number of possible signal types. For example, such LTF-based classification may be used to classify the respective channel bandwidths associated with the signal (e.g., as being either 1 MHz or 2 MHz channel bandwidth). Generally, one or more LTF fields within one or more signals are employed for any of a number of additional uses beyond or in addition to such functions as channel estimation, channel characterization, etc.
