摘要： Range extension within single user, multiple user, multiple access, and/or MIMO wireless communications. A given communication device designed and implemented for operation in accordance with a given communication protocol, standard, and/or recommended practice operates in accordance with a down-clocked manner to effectuate operation in accordance with at least one other communication protocol, standard, and/or recommended practice. For example, first channelization may undergo down-clocking by a particular and desired ratio to generate a second channelization. As such, at least one portion of a physical layer (PHY) of a given communication device may be leveraged for use in at least one other or additional operational mode based upon the down-clocking employed. Sub-channel and/or channel adaptation may be made based upon any of a number of considerations (e.g., independently by one device, cooperatively by two or more devices, local and/or remote operating condition(s) [or changes thereof], etc.).

摘要： Frequency selective transmission within single user, multiple user, multiple access, and/or MIMO wireless communications. Adaptation among different respective sub-channels and/or channels is effectuated within a wireless communication system. Such a wireless communication system may include an access point (AP) and one or more wireless stations (STAs). The respective channelization employed for various communications between the devices within such a wireless communication system may be adapted based upon any of a number of considerations. For example, a receiver communication device may indicate to a transmitter communication device one or more preferred sub-channels and/or channels on which subsequent communications are to be performed. Alternatively, a transmitter communication device may employ such information provided from one or more receiver communication devices as one of multiple respective considerations regarding which one or more sub-channels and/or channels on which subsequent communications are to be performed.

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： An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes. These principles can be expanded upon and can be applied in many communication systems.

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： In an orthogonal frequency division multiplex (OFDM) communication system, data bits are assigned to several carriers to create frequency redundancy in the transmitted waveform. Uniformly spaced carriers occupy the frequency band of the OFDM signal. Multipath nulls caused by reflections of the transmitted signal can occur at periodic frequency intervals, for example in a coaxial cable. A non-periodic pattern of bit allocation to carriers creates frequency diversity that is resistant to periodic multipath nulls existing in the communication channel.

摘要： Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

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： 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.
