| 20090279511 | MULTI-TRANSCEIVER MOBILE COMMUNICATION DEVICE AND METHODS FOR NEGATIVE SCHEDULING - Embodiments of a multi-transceiver mobile communication device and methods for negative scheduling are generally described herein. Other embodiments may be described and claimed. In some embodiments, a broadband wireless access network (BWAN) transceiver of a multi-transceiver mobile communication device may transmit a negative scheduling (NS) request frame that includes time-related QoS parameters to a BWAN base station to request one or more negative allocation (NA) periods. In response, the base station may transmit a NS management response frame to indicate when NA periods are to occur during subsequent BWAN frames. The BWAN base station may also transmit a subsequent NS response frame to update the configuration of the NA periods including an indication of when a subsequent NA period is to occur. | 11-12-2009 |
| 20100027525 | Techniques to improve co-existence among multiple radios - Techniques are described that can be used to permit coexistence of different radios. Preambles of frames from a first radio are detected. If the preambles occur within a prescribed period of one another, then a frame synchronization signal is transmitted. Based on the timing of the frame synchronization signal, a second radio adjusts the timing of transmit and receive time slots. | 02-04-2010 |
| 20100157971 | Power-efficient media access techniques for wireless networks - Techniques for media access in wireless networks are disclosed. For instance, embodiments may provide a time interval for accessing a wireless communications channel. In addition, embodiments may prevent channel access during the time interval by stations incapable of employing a first channel access technique. This access technique employs an access probability P. | 06-24-2010 |
| 20100220610 | MAC SLOT ALIGNMENT AMONG MULTIPLE WIRELESS STATIONS - A device in a wireless network receives signals and determines media access control (MAC) slot boundaries of the received signals. The MAC slot boundaries are averaged in time, and a local slot boundary is modified in response thereto. The local MAC slot boundary is modified by less than ten percent of a short interframe space until the local MAC slot boundary is within one orthogonal frequency division multiplexing (OFDM) cyclic prefix duration of the averaged MAC slot boundaries. | 09-02-2010 |
| 20100309893 | Techniques for detecting beacons on wireless channels - A wireless local access network (WLAN) radio listens for a beacon for a listening duration on each of multiple channels. Periodically, the WLAN radio changes the channel on which the WLAN radio listens for a beacon. The WLAN radio rotates through all channels until an entire beacon period is listened to. The number of iterations is chosen to minimize the overlap of successive listening durations. The WLAN radio can detect a beacon by detecting an incomplete portion of a beacon. | 12-09-2010 |
| 20100316089 | FREQUENCY SELECTION METHOD TO MITIGATE IN-BAND INTERFERENCE FROM INTER-MODULATION SPUR OF THE COLLOCATED RADIO TRANSMITTER - A radio transmitter select its operating frequency based on the frequency characteristics of a collocated receiver and clock harmonics. | 12-16-2010 |
| 20100331000 | MACRO-TO-FEMTO CELL RESELECTION - The present invention discloses a method including: storing identification information or location information for a handover previously performed by a mobile system; estimating when the mobile system enters within a coverage area of a target femtocell; recognizing the coverage area based on the identification information or the location information; and scanning for the target-femtocell prior to handover. | 12-30-2010 |
| 20110064034 | Techniques for Requesting Bandwidth Allocation - Techniques for requesting uplink bandwidth. The request can include a request for bandwidth that will be received at a specified delay from when the request was transmitted. Accordingly, the requested uplink bandwidth may be available at a future time when needed by an application or other logic. | 03-17-2011 |
| 20110134891 | WiMAX Scheduling Algorithm for Co-Located WiFi and WiMAX Central Points - After receiving an indication that a co-located central point is receiving co-location interference, a scheduling algorithm may be initiated. The scheduling may include allocating equal number of central points within each WiMAX frame. Each central point is allocated into a minimum number of frames subject to WiMAX capacity constraints. | 06-09-2011 |
| 20110138244 | DETERMINING HYBRID AUTOMATIC REPEAT REQUEST (HARQ) TIMING - A communication apparatus (CA) such as a mobile node/station (MN), a base station (BS), or a radio station (RS) may support determination of HARQ timing. The CA may generate at least in part one or more generalized frames such as a frequency division duplex (FDD) frame or a time division duplex (TDD) frame. The generalized FDD and TDD frames may include support to determine the HARQ timing considering various factors, which may affect the HARQ timing. The FDD and TDD frames may include information corresponding to various factors to determine the HARQ timing considering factors such as DL/UL ratio, number of sub-frames per frame, variable transmission time interval (TTI), relay zones, legacy IEEE® 802.16e zones, and availability of ACKCH. | 06-09-2011 |
