摘要： Systems and methodologies are described that facilitate mitigating effect of non-linear distortion from a power amplifier on a spectral mask margin. Power limit indications can be analyzed in scheduling mobile devices. Mobile devices with power limits can be scheduled on inner subbands. The power limits can be based at least in part on power amplifier headroom information. Other mobile devices can employ remaining portions of an allocated spectrum. Further, mobile devices can evaluate and establish a power amplifier backoff based upon the subband scheduling.

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： For certain embodiments, a preamble sequence associated with a particular number of transmit antennas may allow a receiving mobile station to determine the number of transmit antennas used for transmission. The preamble sequence may be selected from one of a set of Constant Amplitude and Zero Auto Correlation (CAZAC) sequences corresponding to all of the supported number of transmit antennas. As a result, a receiving station may be able to determine the sequence sent by correlation and, thereby determine the number of antennas used for transmission. Given the number of transmit antennas, the mobile station may then perform MIMO channel estimation during initial synchronization to recover the channel taps between each transmit and each receive antenna.

摘要： Methods and apparatuses that apply a time-varying delay to symbols to be transmitted from one or more antennas are provided. In a first embodiment, first and second transmission orders for samples in first and second data symbols, respectively, are determined. First and second cyclic prefixes are appended to the beginnings of the first and second transmission orders, respectively. The first and second data symbols are then provided to the same antenna for transmissions beginning at different time slots in accordance with a delay diversity scheme. In a second embodiment, either the first data symbol or the second data symbol can be provided to different antennas for transmissions beginning at different time slots in accordance with a delay diversity scheme.

摘要： Apparatus, systems and methods for estimating a position of a mobile terminal (MT) using joint probability distribution values are disclosed. In an example, the MT is capable of receiving signals from a plurality of access points. The MT receives a map of expected measurements for a parameter observable by the MT, from any of a plurality of hypothesis locations. The expected measurements are predictive of a value of the parameter observed by the MT, when the MT is proximal that hypothesis location. The MT captures measurements of the parameter for the plurality of access points, computes interim vectors for the hypothesis locations using the captured and expected measurements, computes joint probability distributions for the interim vectors using a covariance matrix, and filters the joint probability distributions to produce an estimated position of the MT.
