  • Publication number: 20110130142
    Abstract: A femtocell, a base station, a femto gateway, and communication methods thereof are provided. The femtocell is connected to the femto gateway via the base station. The femtocell turns off its RF transceiver when the RF transceiver is idle for a predetermined time interval. When the base station determines that a mobile station enters its signal coverage, the base station transmits a notification signal to the femto gateway. After receiving the notification signal, the femto gateway transmits a turn-on signal to the femtocell via the base station. After receiving the turn-on signal, the femtocell turns on its RF transceiver and transmits an acknowledgement signal to the femto gateway. Since the femtocell only turns on its RF transceiver when a mobile station needs its service, the femtocell consumes less power. In addition, interferences between femtocells can be reduced.

  • Patent number: 7634285
    Abstract: A wireless communication system using channel access based on a contention approach and method thereof is disclosed, which allocates plural sets of time slots in a predetermined contention interval, wherein each set of time slots further includes plural adjacent overlapped time slots. A channel requester transmits a contention message to a channel allocator at a time slot based on an interleaved method after the channel requester completes count down of a predetermined time, so that the positions of the headers of the contention messages in the adjacent time slots of each set of time slot are different. Thus, if the contention message transmitted by the channel requester collides with the contention message of the adjacent time slot, the channel allocator can parse the headers of the collided contention messages and respectively allocate plural special channel times for communicating with the channel requesters.
