摘要： Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.

摘要： Downclocking and/or adaptive sub-carriers for single user, multiple user, multiple access, and/or MIMO wireless communications. Communication device operation within a wireless local area network (WLAN/WiFi) is effectuated in the frequency spectra typically associated with television broadcast channels. Operation is made on a secondary non-interfering basis to such television broadcast channels. Any desired channel bandwidth (e.g., 6 MHz, 7 MHz, 8 MHz, etc.) may be employed. Adaptation with respect to the number of data sub-carriers within different respective packets may be made in accordance with two or more respective operational modes. For example, modification of the number of data sub-carriers in different respective packets may be made to increase the signal bandwidth from a first band was to a second bandwidth. Also, appropriate frequency down-clocking of a first channel bandwidth may be performed to generate the desired channel bandwidth to be employed within an available television broadcast channel bandwidth.

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： 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。
