摘要： Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented. Examples communicate the CSD mode in a signaling message. Specifically, a CSD mode is set in an access point the sent to a mobile device. The signaling messages may be either a point-to-point message or a broadcast message. The access point or location server may set the current CSD mode from a plurality of mobile devices by crowd sourcing. For example, the plurality of mobile devices may report what CSD mode was detected. Alternative, the plurality of mobile devices may send a channel impulse response (CIR), or the like, to a location server and the location server may determine what CSD mode is currently used by the access point.

摘要： Apparatus and methods are directed to calibrating a delay within a wireless access point for determining a position of a mobile station. One method includes receiving an initial packet at an eavesdropping device, receiving a response packet, sent by another entity, at the eavesdropping device, computing a time difference based upon the packet arrival times, and providing the time difference to a position determination entity. Another method includes providing a request to appropriate eavesdropping devices to send information, receiving, from each appropriate eavesdropping device, a time difference which represents a difference in a time of arrival of a packet transmitted by the wireless access point and a time of arrival of a packet transmitted by the mobile station, determining a processing delay estimate based upon the time differences, and determining a position of the mobile station based upon the processing delay estimate and the received time differences.

摘要： A time-of-propagation distance-determining method involves sending a probe request from a handset to an AP and receiving a return ACK. The time it takes for the probe request to propagate to the AP, the turnaround time, and the time it takes the ACK to propagate back to the handset is measured on the handset. The turnaround time is subtracted from the measured time, and the result is used to make a distance determination. In order to reduce power consumption, the “lowest overall transmit energy” setting that will give acceptable reception of a probe request sent by the handset to the AP station is determined. The lowest overall transmit energy setting involves a bit rate setting and a transmit power setting. The lowest overall transmit energy setting is used to send probe requests when probe requests are sent from the handset in carrying out a time-of-propagation distance-determining transaction.
摘要翻译：传播时间距离确定方法包括从手机向AP发送探测请求并接收返回ACK。在手机上测量探测请求传播到AP所需的时间，周转时间以及ACK传播回手机所花费的时间。从测量时间中减去周转时间，结果用于进行距离确定。为了降低功耗，确定了能够接收手机向AP站发送的探测请求的最低总的发射能量设定。最低的总发射能量设置涉及比特率设置和发射功率设置。当进行传播时间距离确定交易时，从手机发送探测请求时，最低的总发射能量设置用于发送探测请求。
