Abstract: Methods and apparatus for expressing two or more extended information elements (IEs) of a MAP message using a single Extended or Extended-2 Downlink Interval Usage Code (DIUC) or Uplink Interval Usage Code (UIUC) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame are provided. This enhancement, called extensible Extended IE mapping, allows the WiMAX network to include more IEs into the DL-MAP and UL-MAP messages as the IEEE 802.16 family of standards evolves. Without this enhancement, all of the new IEs may most likely have to be included in the data bursts, and a user terminal (e.g., a mobile station) cannot decode these data-burst IEs unless the user terminal receives the Downlink Channel Descriptor (DCD) message(s).

Abstract: Methods provided may generally include sending a BS of a first RAT a request message indicating a set of MIMO resources to reallocate; during a scan duration, communicating with the BS of the first RAT using non-reallocated MIMO resources and communicating with a BS of a second RAT using reallocated MIMO resources; and during a normal duration, communicating with the BS of the first RAT using the reallocated and non-reallocated MIMO resources. Apparatus provided may generally include logic for receiving a request message indicating a set of MIMO resources of the MS to reallocate; logic for, during a scan duration, communicating with the MS in a first transmission mode assuming the use of only non-reallocated MIMO resources by the MS; and logic for, during a normal duration, communicating with the MS in a second transmission mode assuming the use of the reallocated and non-reallocated MIMO resources by the MS.

Abstract: Certain embodiments of the present disclosure allow a mobile station (MS) to proactively request neighbor base station information from a serving base station, for example, if a mobile neighbor advertisement (MOB_NBR-ADV) message is not received (or expected) in a predetermined time period.

Abstract: Certain embodiments of the present disclosure provide techniques for selecting a new cell, from a plurality of cells in a boundary area between first and second coverage areas, for a wireless device. The first and second coverage areas may include, for example, include cells controlled by first and second operators or cells in different time zones. In either case, the techniques may facilitate giving preference to cells in a same coverage area as a current cell. The wireless device may then select a cell from the list of neighbor cells as the new cell.

The method may also include determining user preferences regarding system selection based on the user input. The method may also include creating a preferred roaming list (PRL) based on the user preferences. The method may further include using the PRL to scan for available networks and channels and to find serving systems.

The method may further include establishing a connection with the home NAP/NSP.

Abstract: In accordance with a method for implementing Short Message Service (SMS) in a WiMAX network, a mobile station may send a mobile station SMS request message to a base station. The mobile station SMS request message may include mobile-originated SMS data. In response, the base station may send a base station SMS response message back to the mobile station. For mobile-terminated SMS data, the base station may send a base station SMS request message to the mobile station. The base station SMS request message may include the mobile-terminated SMS data. In response, the mobile station may send a mobile station SMS response message to the base station. Ranging procedures and medium access control (MAC) management messages may be used to allocate bandwidth for the various messages.

Abstract: A base station may broadcast quality of service (QoS) and loading information to mobile stations. When a mobile station determines that there is demand for a new traffic connection, the mobile station may select a base station from which to request the desired traffic connection based on the QoS information and the loading information received from one or more base stations.

Abstract: In accordance with a method for supporting short burst messages over a wireless communication network, mobile-originated short burst messages may be sent using at least one of a message-based approach and a service flow-based approach. Also, mobile-terminated short burst messages may be received using at least one of the message-based approach and the service flow-based approach.

Abstract: Methods and apparatus for notifying a mobile station (MS) of service flow parameters supported by neighbor base stations, such that the MS may select a suitable neighbor base station (BS) candidate (i.e., a target BS) for performing a handover are provided. The notification may occur via handover messages, such as a BS Handover Request (MOB_BSHO-REQ) message or a BS Handover Response (MOB_BSHO-RSP) message, with a Service Level Supported field added, indicating the service flow parameters supported by the neighbor BSs. In this manner, service quality levels of data exchanges may be maintained as an MS is handed over from one BS to another.

Abstract: Methods and apparatus for conserving battery power in a mobile device for wireless communication by dynamically adjusting the clock frequency and/or the voltage of the device's processor according to the Media Access Control (MAC) layer state are provided. By using a higher clock frequency and/or a higher voltage for a normal operation state with large amounts of data traffic and lower clock frequencies and/or lower voltages for other MAC layer states (e.g., acquisition, network entry, and sleep/idle states), battery power may be conserved, thereby extending the time in which the device may operate between battery charging cycles.

Abstract: Methods and apparatus for using a location of a mobile station (MS) to assist network entry and initialization, scanning, and/or handover operations in a radio access technology (RAT), such as WiMAX (Worldwide Interoperability for Microwave Access), are provided. The location of the MS may be ascertained by determining the Global Positioning System (GPS) coordinates of the MS internally or by receiving the location from a GPS device external to the MS. Knowledge of the current or future location of the MS may reduce the amount of base station (BS) information transmitted to the MS; may reduce the power consumption and the amount of time spent during network entry, scanning, or handover; and may increase the bandwidth usage efficiency.

Abstract: A method for implementing Short Message Service (SMS) in a wireless communication network may be implemented by a mobile station. The method may include sending mobile-originated SMS data while in idle mode. Ranging procedures may be used to send the mobile-originated SMS data. The method may also include receiving mobile-terminated SMS data while in the idle mode. Receiving the mobile-terminated SMS data may include receiving a broadcast page message from a base station, and the broadcast page message may include an identifier for the mobile station.

Abstract: Methods and apparatus for using network topology and coverage information from one radio access technology (RAT) network to assist acquisition of another different RAT network for a multi-mode mobile station (MS), such as acquiring a WiMAX (Worldwide Interoperability for Microwave Access) network based on topology and coverage information about a 3G (Third Generation) network and vice versa, are provided. Base station (BS) acquisition assisted in this manner may provide for quick restoration of a previously interrupted or deactivated network service, while decreasing the power consumption of the multi-mode MS during a power savings state because periodic scanning and registration need not occur.

Abstract: To provide “transparent” broadcast services for a multi-mode wireless device capable of communicating with multiple wireless communication networks, a composite set of pertinent parameters for broadcast messages used by the multiple networks is defined. The parameters of the broadcast message for each network are mapped to corresponding parameters in the composite set. The composite set of parameters is used for processing and displaying broadcast messages received from the multiple networks. A broadcast message for each network (e.g., a CBS message in GSM or a broadcast SMS message in CDMA) is received and processed in accordance with the parameters of the message and filtering configurations applicable for the network. The parameters of the broadcast message are mapped to corresponding parameters in the composite set. The broadcast message is further processed and displayed based on the parameters in the composite set.

Abstract: An apparatus and method are disclosed for system provisioning in a multimode wireless communication device. A multimode wireless communication device may store multiple system provision information internally, or combine system provision information stored internally with removable memory devices, which store additional system provision information. The multimode wireless device may simultaneously have access to a plurality of valid system provision information for a plurality of systems. The wireless device attempts to validate one of the plurality of stored system provision information using a hierarchy. The hierarchy may be established by a phone manufacturer or may be programmed by a service provider or a user. The wireless device attempts to validate system provision information based on the hierarchy. Once a system provision is validated, the device activates service or registers in the system. If a less desirable system is acquired, the device may periodically attempt to validate preferred systems.

Abstract: A method for priority-based network congestion control may be implemented by a network entity. The method may include determining one or more priorities associated with a service request that is being processed by the network entity. The method may also include determining resource availability. The method may also include determining whether to grant the service request based on the one or more priorities associated with the service request and the resource availability.

Abstract: Methods and apparatus for allocating, modifying, and terminating a fixed data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame are provided. With sticky region allocation, the sticky region may be negotiated during the establishment of a connection between a base station and a user terminal, and a single MAP information element (MAP IE) may inform the user terminal of the location of the sticky region. Then, a user terminal can receive/send data bursts for a certain connection in multiple OFDM/OFDMA frames without needing a MAP IE for locating each burst in subsequent frames. Accordingly, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of OFDM/OFDMA wireless systems.
