An e-commerce mechanism tries to dynamically estimate or refine a profile of a buyer and hence change their negotiation strategy in a dynamic and an on-line manner. An e-commerce site can negotiate with a customer based on his or her profile. The e-commerce site may sell one or more types of items to various customers. These customers may be brokers, other intermediaries, businesses or consumers. Similarly, the e-commerce site may be a broker, an auctioneer, an intermediary, a seller, or even a manufacturer. In one specific case of this invention, the existing data on various customers' past purchases, buying behavior, demographics and other parameters is studied to arrive at attributes which are then used to segment customers into various profiles. The profiles depend not only on the demographic factors but also on factors like the season, the time of day, the geographical area and the cultural upbringing. When a new customer comes to the e-commerce site, the customer is assigned to a pre-specified profile in an on-line manner. The e-commerce site then negotiates with the customer according to the customer's present profile. As the customer negotiates, the customer's profile is dynamically updated to incorporate the customer's actions. Different profiles may yield different negotiation strategies and also different results, i.e., value, price, points, delivery dates, etc. Both the customer and the e-commerce site can negotiate on the basis of each other's dynamic profiles and come to a mutually agreed settlement.

A method and system generates, distributes, stores, redeems, validates and clears electronic manufacturer coupons and electronic store coupons. A coupon mint generates unforgable blank digital coupons. The promoter of the offer then writes the terms and conditions and other details of the offer, on blank coupons to customize these. These customized coupons are digitally signed by the promoter and distributed to potential customers. A customer may either present these coupons electronically for redemption to an online store, or print these coupons and present them to a conventional offline store. The store may check the authenticity of a coupon by verifying the digital signature and also verifying if the coupon has not been used earlier by contacting a verification center. The store collects all redeemed coupons and sends these to manufacturer for clearing. The verification center verifies that the coupon is authentic and has not already been used before.

An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.

Methods and apparatus for using code-division multiple access (CDMA) to transmit information via orthogonal frequency-division multiplexing (OFDM) to convey information from user terminals to an access point (AP) in a wireless local area network (WLAN) are provided. By using CDMA to convey information, a propagation delay between an access point (AP) and a user terminal may be determined by the AP, and timing adjustment information based on the delay may be sent to the user terminal. In this manner, subsequent uplink (UL) transmissions from multiple user terminals may be received simultaneously by the AP, despite the multiple user terminals having potentially different propagation delays.

Methods, computer-readable media, and systems for modifying redistribution sets of users based on expiration time. A redistribution set including multiple present users to whom selected content is presentable for a pre-defined duration is received. Multiple past users who were included in the redistribution set have previously been removed from the redistribution set based on an expiration of the pre-defined duration. In response to detecting a modification to the pre-defined duration, the redistribution set of users is modified to include one or more past users or to exclude one or more present users. The redistribution set thus modified is used to target content to users in the modified redistribution set.

The subject matter disclosed herein relates to a system and method for receiving, by a first mobile station, a signal transmitted from a second mobile station and addressed to a communication device (e.g., a communication device having a known location). The signal comprises a location estimate for the second mobile station. A range from the first mobile station to the second mobile station is estimated based at least in part on a measured signal strength of the received signal.

Certain aspects of the present disclosure provide a heuristic algorithm for calculating accurate target SINR values for the minimum mean square error (MMSE) beamforming algorithm to decrease the complexity of the MMSE algorithm. The heuristic algorithm for calculating target SINR values considers practical system constraints, such as frequency selective channels, power amplifier distortion, imperfect channel state information as well as limited computing power at the access point.

Different methods of signaling between an access point and user terminals in a multiuser wireless system for performing a minimum mean square error (MMSE) precoding at the access point preceded with eigenmode selection are provided. For one embodiment of the present disclosure, a compact feedback may be utilized between a plurality of user terminals and the access point. For another embodiment of the present disclosure, a hybrid feedback may be utilized between the plurality of user terminals and the access point. For yet another embodiment of the present disclosure, a full feedback may be utilized between the plurality of user terminals and the access point.
