  • Patent number: 10285173
    Abstract: A two-hop link transmission method and apparatus are provided. The method includes establishing a two-hop link and scheduling transmission on the two-hop link in a Device-To-Device (D2D) communication network. The two-hop link transmission method includes identifying neighbor terminals available for communication with the transmission terminal, selecting one of the neighboring terminals as a recipient terminal, determining a type of a link to be established with the selected neighboring terminal between a single-hop link and two-hop link types, selecting, when the two-hop link type is determined, a relay terminal among the neighboring terminals, establishing the two-hop link with the recipient terminal via the relay terminal, allocating a Multi-Hop Connection Identifier (MCID) for the two-hop link, and transmitting data to the recipient terminal through the two hop link.

  • Patent number: 8934912
    Abstract: In a method for deciding an unregistered macrocell user equipment (MUE) adjacent to a femtocell base station (home evolved node B; HeNB), a macrocell base station (macro evolved node B; MeNB) decides occurrence of an unregistered MUE influenced by interference from a HeNB among MUEs. The MeNB requests an adjacent HeNB to transmit system information (SI) of the adjacent HeNB of which interference has influence on the unregistered MUE, and the unregistered MUE searches for the SI of the adjacent HeNB and transmits the searched SI to the MeNB, when it is decided that the unregistered MUE has occurred. The MeNB informs the adjacent HeNB of existence of the unregistered MUE using a closed subscriber group identifier (CSG ID) of the SI of the adjacent HeNB, transmitted from the unregistered MUE.

  • Patent number: 8750148
    Abstract: Provided is a handover apparatus and method for a terminal based on a received signal strength (RSS) and a radial velocity. The handover method may measure an RSS from a currently accessed base station and RSSs from candidate base stations for handover, may measure a radial velocity with respect to the currently accessed base station and radial velocities with respect to the candidate base stations for handover, and may perform a handover by determining a base station for handover based on the measured RSSs and the measured radial velocities when the RSS from the currently accessed base station is less than or equal to a reference RSS.

  • Patent number: 8094617
    Abstract: Disclosed is a method of recognizing an available channel in order to prevent channel occupation requirements from colliding with each other when one wireless channel is shared by plural terminals in a CSMA/CA mechanism using an IEEE 802.15.4 protocol slot, the method including: a first step of initializing a counter, CW, as 2, the CW being used for CCA which an attempt to perform is made before frame transmission; a second step of determining if a required channel is occupied; a third step of decreasing the CW by 1 when the channel is idle in the second step; a fourth step of re-determining if the channel is occupied; and a fifth step of, based on a determination result in the fourth step, determining if the CW is 1 when the channel is occupied.
