20080214213DETERMINING LOCATIONS OF MOBILE STATIONS IN WIRELESS NETWORKS - Wireless network methods and apparatuses that may determine and provide, in real-time, the geographical locations of mobile stations of the wireless network are described herein. In one implementation, in order to determine the location of a mobile station (MS), the MS may obtain from a navigation service a decryption key to decrypt encrypted location information of multiple base station's (BS's) in its local area. The encrypted location information of the BS may then be decrypted and based at least in part on the recovered location information of the BS, determine the location of the MS. In another implementation, in order to determine and provide the location of an MS of a wireless network, a combination of location agents, location controller, and a location server may be employed to determine and provide the current location of the MS to requesting authorized clients.09-04-2008
20080259835Locating content in broadband wireless access networks - In some embodiments, only one multicast connection identifier is used in a WiMAX network per zone. This may result in power savings because it is not necessary for the mobile station to query a base station to obtain the correct information about how to locate desired channels in a WiMAX multicast. Instead, the mobile station may be maintained in a lower power consumption mode in which it need not transmit, but only receives information. This is because the mobile station has all the information it needs about what channels are available and can simply tune using a logical media channel identifier to the appropriate channel to receive the desired content without having to transmit a message to the base station to identify the correct channel.10-23-2008
20080261623TECHNIQUES TO ENHANCE LOCATION ESTIMATION IN AN OFDMA BASED SYSTEM - An embodiment of the present invention provides an a method, comprising determining the position of a mobile station in a wireless network by transmitting a single or multi tone location beacon by the base station on a downlink or mobile station on an uplink with focused power on at least one tone.10-23-2008
20080287068MULTICARRIER TECHNIQUES FOR WIRELESS SYSTEMS - Multicarrier techniques for wireless communications system are described. An apparatus may comprise a carrier management module to define a primary carrier for use by a multicarrier communications system to communicate control information, and a secondary carrier for use by the multicarrier communications system to communicate media information, with the secondary carrier having a communication parameter and technology that is potentially different from the primary carrier. Other embodiments are described and claimed.11-20-2008
20080311931LOCATION SUPPORT IN WIRELESS NETWORKS - Various embodiments of the invention determine and/or enhance the location of a wireless mobile station in a WiMAX network, and provide that location to a requesting device. Some embodiments produce more that one determination of the location, using different sources for the information, and combine the different determinations to produce an enhanced version of the location.12-18-2008
20090257389METHOD AND APPARATUS FOR EFFICIENT SCHEDULING IN BROADBAND WIRELESS ACCESS NETWORKS - The various inventive embodiments relate to arrangement of information elements (IEs) for persistent and/or dynamic allocations in a wireless broadband network and include optimization techniques to eliminate the repetitive information fields from the downlink (DL)-Persistent-IEs, uplink (UL)-Persistent-IEs, DL-IEs, and UL-IEs. Elimination of repetitive information fields reduces MAP overhead. In addition embodiments relate to methods to use the same hybrid automatic repeat request (HARQ) region to contain persistent as well as non-persistent allocations. The use of the same HARQ region for persistent as well as non-persistent allocations further reduces the MAP overhead as it requires a single header to define the HARQ region instead of the two headers that are required to define two different HARQ regions: one for persistent allocation and the second one for non-persistent allocations.10-15-2009
20100080308VIRTUAL MULTICARRIER DESIGN FOR ORTHOGONAL FREQUENCY DIVISION ... - Embodiments of the present invention provide a virtual multicarrier design for orthogonal frequency division multiple access communications. Other embodiments may be described and claimed.04-01-2010
20100105393System and Method for Handoff Between Base Stations - A system and method for handoff are provided. A mobile station performs a make-before-break handoff of a control channel between a serving and target base station and a break-before-make handoff of a traffic channel between the serving and target base stations. The traffic channel handoff is performed after the control channel handoff has completed.04-29-2010
20110044213SYSTEM, METHOD AND APPARATUS FOR AN EFFICIENT INFORMATION BROADCAST IN A MULTI-CARRIER WIRELESS NETWORK - Embodiments of an apparatus, system and method are described for a base station. Notification from a mobile station in a network may be received. A multi-carrier advertisement with a base station multi-carrier configuration may be sent. The base station multi-carrier configuration may include at least one carrier index associated with a carrier frequency operated on by the base station. Other embodiments are described and claimed.02-24-2011
20110044229METHOD AND APPARATUS FOR ENHANCED MULTICAST BROADCAST SERVICES - A method, system, apparatus and article are described for managing enhanced multicast broadcast services. In some embodiments, for example, a first connection may be established using a first wireless communication protocol, scheduling information for one or more multicast or broadcast data services may be received using the first wireless communication protocol, one or more of the multicast or broadcast data services may be selected, and a second connection using a second wireless communication protocol may be established to receive the one or more selected multicast or broadcast data services. Other embodiments are described and claimed.02-24-2011
20110044244MAC/PHY IDENTIFICATION OF BASE STATION TYPES AND THEIR PREFERRED AND RESTRICTED ACCESS - Embodiments of a system and methods for identification of base station types are generally described herein. Other embodiments may be described and claimed.02-24-2011

Other embodiments may be described and claimed.05-12-2011
20110110338LOCATION DETERMINATION IN WIRELESS COMMUNICATION SYSTEMS - Briefly, in accordance with one or more embodiments, a mobile station receives a location beacon transmitted from multiple base stations based on a transmission plan for a predefined downlink location based services zone in the superframes of a signal frame structure. The transmission plan includes spreading transmissions of the location beacon that are unique to respective base stations. The mobile station identifies the base stations based on the respective location beacons and the transmission plan. The mobile station identifies a present location based on the location beacons and the identities of the base stations that from which the location beacons were received.05-12-2011
20110122833WIRELESS DEVICE AND METHOD FOR EFFICIENTLY PAGING IDLE-MODE MOBILE STATIONS IN MULTICARRIER SYSTEMS - Embodiments of a mobile station and a method performed by a base station for transmitting a paging message to an idle-mode mobile station are disclosed herein. In some embodiments, a multicarrier paging information (MC-PAG-Info) message is transmitted to indicate a time-slot and paging carrier for a subsequent transmission of a paging message to an idle-mode mobile station. The idle-mode mobile station may monitor the indicated paging carrier during the indicated time-slot of a paging listening interval for receipt of a paging message directed to the idle-mode mobile station. In some embodiments, the indicated time-slot and the paging carrier are determined by the idle-mode mobile station using a device identifier of the idle-mode mobile station and hash modulo parameters provided within the paging information message.05-26-2011
