  • Patent number: 8385308
    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).

  • Patent number: 8385275
    Abstract: A subscriber station may determine whether a service flow between the subscriber station and a base station is retained during an idle mode of the subscriber station. The subscriber station may reactivate the service flow when the subscriber station exits the idle mode. The subscriber station may monitor whether the service flow has data activity. The subscriber station may delete the service flow if there is no data activity.

  • Patent number: 8335190
    Abstract: A mobile station may send a first handover indication message to a serving base station. The first handover indication message may include a first resource retain time. The mobile station may start a resource retaining timer using the first resource retain time. The mobile station may perform handover procedures. The mobile station may determine whether the resource retaining timer is within a threshold of expiring. The mobile station may send a second handover indication message to the serving base station if the resource retaining timer is within the threshold of expiring.

  • Patent number: 8254978
    Abstract: Methods and systems or broadcasting the fast power control message in wireless communications systems are provided. In certain embodiments, the methods and systems can include receiving Carrier to Interference-plus-Noise Ratio (CINR) values from multiple mobile stations, determining a power adjustment value for each mobile station based on the CINR values, grouping the mobile stations based at least on the CINR values, and transmitting a fast power control message for each group with a different number of repetitions.

  • Patent number: 8255010
    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.

  • Patent number: 8218466
    Abstract: A base station and a subscriber station may negotiate paging parameters so that the subscriber station can enter idle mode. After the subscriber station has entered idle mode, the base station may change at least one paging parameter at the base station. The base station may direct the subscriber station to change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode. The subscriber station may change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode.

  • Patent number: 8219099
    Abstract: A subscriber station may identify base stations that have sufficiently strong signal strength so that the base stations are candidates to be used for network entry. The subscriber station may determine which of the candidate base stations is least utilized. The subscriber station may select the least utilized base station for network entry.

  • Patent number: 8094635
    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.

  • Patent number: 8081949
    Abstract: Embodiments of the present disclosure may provide a method of managing multi-mode operations such that a multi-mode MS may utilize the WiMAX sleep mode for monitoring the paging intervals of other supported radio access technologies. For example, certain embodiments may enable the MS to determine a set of WiMAX sleep mode parameters that align a WiMAX sleep window with a CDMA page listening window. Additionally, certain embodiments may provide enhanced MOB_SLP-REQ and MOB_SLP-RSP messages enabling the multi-mode MS to establish a WiMAX sleep mode based on the previously determined WiMAX sleep mode parameters. As a result, embodiments of the present disclosure may enable an MS to manage multi-mode operations, such that the MS 430 may better employ the WiMAX sleep mode for switching from the WiMAX network to the CDMA network to listen for CDMA paging.

  • Patent number: 7961679
    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.
