  • Neighbor-assisted contention resolution for multi-user communication
    Patent number: 6594247
    Abstract: A contention resolution method includes the steps of determining a contention has occurred and requesting contention resolution from radios in the system (604). Radios in the system receive the request and do not transmit in the next control frame (606). Group leader radios (202, 208 and 214) transmit the identification code they were able to demodulate in the previous frame to the master radio (608). The master radio (212) receives the information from the group leaders and transmits a control-channel access message to one of the contending radios (610).
    Type: Grant

    Date of Patent: July 15, 2003
    Assignee: Motorola, Inc.

  • Method for accessing a communication medium
    Patent number: 6353617
    Abstract: A medium access protocol which adjusts number of contention slots in a variable length frame and superimposes a variable window structure over the frame structure. The number of contention slots (24) in a frame (28, 30) is changed on a frame by frame basis by determining if a collision occurred in any contention slot (44). If not the contention slot is removed (48) and if so, the number of slots is increased (52). In high traffic situations, if the average load is greater than a threshold (107, 120) the number of frames in a window is increased (130). If the load drops below the threshold (120), the number of frames per window is decreased (124).
