摘要： 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.

摘要： 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.

摘要： 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.

摘要： Disclosed is a system and a method for polling in an Ethernet Passive Optical Network (EPON). The system includes: multiple Optical Network Units (ONUs) for sharing optical channels of the EPON with one another and transmitting traffic; and an Optical Line Terminal (OLT) for discriminating a plurality of ONUs gaining access to the EPON among the multiple ONUs and then collecting routing information on the plurality of ONUs gaining access to the EPON, and for classifying the plurality of ONUs gaining access to the EPON into two or more ONU groups according to the collected routing information and then carrying out forming a polling cycle and allocating bandwidth on each ONU group. Therefore, a transmission idle period in a traffic channel is not only minimized, but an availability ratio of traffic channels can also be maximized.

摘要： Disclosed is a method fox allocating upstream transmission bandwidth so as to prevent Inter-Scheduling Cycle Gaps (ISCGs) from occurring in an N number of Optical Network Units (ONUs) by using an m number of wavelength channels for upstream transmission in a Wavelength-Division Multiplexing (WDM)-Ethernet Passive Optical Network (EPON). The method includes: grouping the ONUs to be allocated each of the m number of wavelength channels; and performing a Dynamic Bandwidth Allocation (DBA) algorithm in order for the grouped ONUs to efficiently use allocated wavelengths and time slots, thereby allocating each wavelength channel. Accordingly, by using a scheme of managing ONUs by each group, it is possible to more efficiently allocate bandwidth than the online scheduling scheme. As compared with the offline scheduling scheme, ISCGs caused by bandwidth allocation do not occur.
