Abstract: Provided are a coexistence management system for measuring channel information between spectrum sharing devices and a method thereof. The coexistence management system for measuring channel information between spectrum sharing devices includes: a plurality of coexistence enablers (CEs) which is provided for each of the plurality of white space objects (WS0s) having at least one measurement capability of measuring channel information on an operation channel that is being used; a coexistence manager (CM) which is linked with at least one CE within a group to confirm measurement capability of a corresponding WSO and receives channel information on the operation channel from one or more WSOs within neighbouring groups according to the confirmed result; and a coexistence discovery and information server (CDIS) which registers at least one measurement capability for each of the plurality of WSCs.

Abstract: A method for allocating an operating channel priority between frequency sharing systems includes: a coarse channel priority allocating operation of collecting information about a target white space object (WSO) for priority allocation of an operating channel and information about the operating channel, and classifying the operating channel based on a predetermined criterion; and a fine channel priority allocating operation of removing the operating channel by checking its interference level. The information about the target WSO preferably includes channel classification information and coexistence set information such as the license type of the set and network technology information. The operating channel information may include a total occupancy rate and the number of elements in a coexistence set. The coarse channel priority allocating operation may remove operating channels used by a coexistence set element of a license type. The operating channels may be allocated to a first group used by a coexistence set element of the same network technology as the target WSO; or a second group, comprising channels excluded from the first group. Priority of the channels in the groups is allocated in ascending order of a total occupancy rate. Apparatus for implementing the method is also disclosed.

Abstract: PURPOSE: An apparatus for generating multi-wavelength light is provided to have high single mode stability and high yield according to transmission spectra, reduce light loss, improve element reliability, and increase the coupling efficiency of lights. CONSTITUTION: A high reflective coating film(110) is formed on a cross-section of a gain portion(120). The high reflective coating film can be composed of mirror elements having high reflection or a metal or dielectric thin film coating surface. The gain portion generates multi-wavelength lights. Each channel included in the gain portion includes a gain waveguide for providing gains to generated light. A reflecting portion(130) again reflects the lights entering from the gain waveguide to the gain portion. A multiplexing portion(140) multiplexes single mode lights generated in each channel of a distributed bragg reflector laser.
