    • A communications protocol is configured Io determine whether multiple simultaneous communications can take place among a plurality of network devices in a wireless network. In one embodiment, a first network device can determine the maximum interference in can sustain while still conducting intended communications with another network device. The first network device can also compute additional maximum sustainable interference it can tolerate based on current interference levels. The first network device can be configured to communicate its additional maximum sustainable interference to a third network device that wishes to conduct communications in the same time frame. The third network device can be configured to compute its maximum allowable power based on the first device's additional maximum sustainable interference and to further determine the minimum transmit power required to conduct its transmit operation. If the minimum transmit power will cause an amount of interference to the first device greater than its additional maximum sustainable interference, then the communication in rescheduled.
    • 通信协议被配置为确定在无线网络中的多个网络设备之间是否可以发生多个同时通信。 在一个实施例中,第一网络设备可以确定可持续的最大干扰,同时仍然进行与另一网络设备的预期通信。 第一个网络设备还可以基于当前的干扰电平来计算其可以容忍的额外的最大可持续干扰。 第一网络设备可以被配置为将其附加的最大可持续干扰传达给希望在相同时间帧内进行通信的第三网络设备。 第三网络设备可以被配置为基于第一设备的额外的最大可持续干扰来计算其最大允许功率,并且进一步确定进行其发射操作所需的最小发射功率。 如果最小发射功率会对第一个设备造成干扰的量大于其额外的最大可持续干扰,则重新安排通信。

    • A method to enable scheduling communications activities for an electronic communication device configured to communicate across a communication network is provided. The method comprises the steps of scheduling a communication activity during a scheduling window such that the communication activity is scheduled to occur toward the end of a communication window; entering a power-save mode after the scheduling step; and transitioning from the power-save mode prior to the scheduled communication activity. In one embodiment the method can further include a step of conducting the scheduled communication activity and transitioning back to the power-save mode after a next communication activity is scheduled or be implemented to allow the step of conducting the scheduled communication activity and transitioning back to the power-save mode at the end of the next communication window. In one embodiment the transitioning step comprises the steps of awakening from the power-save mode and synchronizing with the communication network, wherein synchronizing can comprise the step of synchronizing with electronic communication device associated with the communication network.

    • Described herein are systems, methods, computer program products, and combinations and sub-combinations thereof for enabling a network device to establish transmit and receive data rates independently from one another. According to one aspect of the invention, the transmit and receive data rates can be decoupled by designating the rate capability of each device for at least one of either its transmitter or receiver. For example, in one embodiment, the rate capability of network device receivers can be designated, and the devices' transmit rate capabilities not announced. The transmit rate capability is known to the transmitting device, while the receive rate capability of the receiving device is announced through its beacon or other scheduling window. Hence, the transmitting device can determine at what data rate to transmit based on the information it receives from the other devices.

    • A system and method for estimating the range between two devices performs two or more ranging estimates with subsequent estimates performed using a clock that is offset in phase with respect to a prior estimate. The subsequent estimate allows estimate uncertainties due to a finite clock resolution to be reduced and can yield a range estimate with a higher degree of confidence. In one embodiment, these additional ranging estimates are performed at n/N (for n = 1,... N- 1, with N>1 and a positive integer) clock-period offset introduced in the device. The clock-period offset can be implemented using a number of approaches, and the effect of clock drift in the devices due to relative clock- frequency offset can also be determined. To eliminate the bias due to clock-frequency offset, a system and method to estimate the clock-frequency offset is also presented.
    • 用于估计两个设备之间的距离的系统和方法执行两个或更多个测距估计,其中使用相对于先前估计相位偏移的时钟执行后续估计。 随后的估计允许由于有限时钟分辨率而降低的估计不确定性,并且可以产生具有较高置信度的范围估计。 在一个实施例中,在设备中引入的n / N(对于n = 1,... N 1,N> 1和正整数)时钟周期偏移量执行这些附加测距估计。 可以使用多种方法实现时钟周期偏移,并且还可以确定由于相对时钟频率偏移而在器件中的时钟漂移的影响。 为了消除由于时钟 - 频率偏移造成的偏差,还提出了一种用于估计时钟频率偏移的系统和方法。
