Abstract: Methods of securely performing online transactions are described which involve two independently controlled web servers. In order to complete a transaction, a user interacts concurrently with each of the two web servers and authentication may occur between the user and each web server and between web servers. Each of the two web servers provide data which is used to complete the transaction and the data provided by the first web server is communicated directly to the second web server for use in the transaction. In an embodiment, the first web server provides a web page which enables a user to specify a variable which is used in the transaction. This is communicated to the second web server which processes the transaction along with an identifier for the message. The identifier may be used in validating the variable before it is used in processing the transaction. Following completion of a transaction this may be reported in real time to the first web server.

Abstract: A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.

In other embodiments of the present invention, voice channels, data channels, and control channels associated with each MS scheduled in a beam may be concurrently transmitted to each MS via the beam associated with the MS.

Abstract: A method, apparatus and system are provided for use in optimizing signal-to-noise ratios at remote wireless devices. A method can receive a signal over a reverse link, determine an angular power profile of the reverse link signal, and determine an antenna weighting vector for the forward traffic signal based on the angular power profile. The determination of the weighting vector can include retrieving the vector from a weighting vector table. Some methods identify boundaries of angular spreads and utilize pre-calculate weighting vectors according to the boundaries. An apparatus can include an antenna array, a wireless receiver that receives reverse link signals, a detector that detects an angular power profile of the signals, a controller that determines a weighting vector and applies the weighting vector to the antenna array when transmitting. Some embodiments are dependent on whether the forward link incorporates a common pilot or per-user pilot signal.
