Patent number: 8768418Abstract: A method and apparatus for transmitting beacon signals in a wireless communications network. For a given cell site, a single frequency may be used for the beacon signal by assigning different beacon signal time slots to different sectors of the cell site. During one time slot, the beacon signal is transmitted to one of the sectors, and during another one of the time slots, the beacon signal is transmitted to a different one of the sectors. Because a single frequency can be used for all of the sectors of a cell site, more frequencies are available for other purposes, such as for user traffic, for example. The invention improves spectral efficiency, reduces adjacent channel interference and co-channel interference and allows power consumption to be controlled.Type: GrantFiled: August 28, 2012Date of Patent: July 1, 2014Assignee: AT&T Mobility II LLCInventors: Ming-Ju Ho, Ali Jabbary, Ramzi Barghouthi

Patent number: 8085720Abstract: Providing for efficient utilization of channel element device ladder (CEDL) resources is described herein. By way of example, a received data request can be packed in a first portion of the CEDL and a received voice request can be packed in a second portion of the CEDL. Subsequent requests can be assigned to contiguous channel elements (CEs) of the CEDL within the first or second portion, as suitable. In addition, non-assigned CEs can be maintained in a third portion of the CEDL, by packing requests initially from opposite ends of the first and second portion, and be re-packing dropped traffic within the CEDL. Accordingly, the subject disclosure provides for efficient utilization of CEDL resources both for incoming voice traffic requests and incoming data traffic requests, by packing and maintaining data, voice and un-assigned CEs in contiguous portions of the CEDL.Type: GrantFiled: January 25, 2008Date of Patent: December 27, 2011Assignee: AT&T Mobility II LLCInventors: Kurt Huber, Daniel Edwards, Robert Taylor, Arthur Brisebois, Ramzi Barghouthi

Patent number: 7450948Abstract: Determining the amount of resources that needs to be provisioned for a wired backhaul link of a wireless network using a probabilistic approach that makes the determination based at least in part on the type of coding scheme selection algorithm used to encode data transmitted by the transceiver to the wireless device over the air interface of the wireless network. Because the type of coding algorithm used depends on the amount of traffic at the air interface, variations in the coding algorithms used over a given period of time can be used to accurately determine the amount of bandwidth or resources that will be required on the backhaul link. Consequently, the amount of resources that should be provisioned for the backhaul link can be accurately determined.Type: GrantFiled: January 15, 2004Date of Patent: November 11, 2008Assignee: Cingular Wireless II, LLCInventors: Yiannis Argyropoulos, Ramzi Barghouthi, Ayman Mostafa

Publication number: 20010049636Abstract: A consumer wireless shopping device, such as a phone or PDA, communicates with a server for completing purchase transactions. Consumers can store preferences, shopping lists, payment methods and shipping addresses on the server to aid with shopping. The location of the of the device is determined, such as by GPS or RF triangulation, and used by the server to help direct consumers to merchant locations for viewing items to be purchased as well as to inform consumers of special sales or desired items within a specified geographic distance. The system allows for use of various delivery options, including in-store pick-up and Internet fulfillment. The system also allows for use of various price-negotiation methods, including use of auction-bidding, competitor price-matching, and buying clubs, and volume discounting.Type: ApplicationFiled: April 16, 2001Publication date: December 6, 2001Inventors: Amir Hudda, Ramzi Barghouthi, Molham Aref
