    Abstract: A communication method is to be performed by a secondary transceiver. The secondary transceiver is operatively associated with a primary transceiver. The primary transceiver is configured to transmit an orthogonal frequency division multiplexing (OFDM) signal that has consecutive OFDM symbols. The OFDM symbol has a fixed OFDM symbol length and includes a cyclic prefix that has a fixed prefix length. The communication method includes steps of: A) upon receipt of the OFDM signal, determining a starting position of the cyclic prefix; and B) transmitting a to-be-transmitted signal during a time corresponding to the cyclic prefix of the one of the OFDM symbols or another one of the OFDM symbols subsequent to the one of the OFDM symbols.

  • Patent number: 9392564
    Abstract: A method and wireless device merge multiple unsynchronized beacon groups in a wireless network, each beacon group including at least one wireless device. A first beacon is received from at least one first wireless device in a first beacon group (S514), the first wireless device having a first directional antenna. A second beacon is received from at least one second wireless device in a second beacon group that is not synchronized with the first beacon group (S516), the second wireless device having a second directional antenna. A first response beacon is relocated (S520) and sent (S522) to the first wireless device in the first beacon group. The relocated first response beacon instructs the first wireless device to relocate the first beacon. Accordingly, the second beacon, the relocated first response beacon, and the relocated first beacon are synchronized.

  • Patent number: 9326121
    Abstract: A fast device discovery protocol with a high success rate for device-to-device (D2D) communication in LTE-A networks is proposed. With the proposed protocol, device discovery is done by monitoring a randomly transmitted beacon from other devices within a pre-defined period. In one embodiment, an eNB receives scheduling requests from D2D UEs and in response allocates a distributed uplink resource for random access of beacon transmission by the D2D UEs. The distributed resource is dynamically allocated based on the number of requesting D2D UEs, a discovery period, and a target discovery probability to minimize the required resource.
