APPARATUS AND METHOD FOR DISTRIBUTED SCHEDULING IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of performing distributed scheduling by a reception device configuring a target link corresponding to one of a plurality of links in a communication network, the method comprising:
- adding up resource allocation demand amounts included in resource information broadcasted by a counterpart transmission device configuring the target link and one or more adjacent transmission devices by a preset Resource Unit (RU);
adjusting self-resource information in consideration of resource position information included in the broadcasted resource information and the added resource allocation demand amount and transmitting the adjusted self-resource information to the counterpart transmission device;
measuring channel quality by a pilot signal received from the counterpart transmission device until data transmission using resources determined based on a predetermined distributed scheduling rule of the broadcasted resource information is performed; and
feeding back channel quality information according to the measurement to the counterpart transmission device.

Abstract
An apparatus is configured to perform a method for performing distributed scheduling by a reception device configuring a target link corresponding to one of a plurality of links in a network in which the plurality of links for device to device communication exist. The method includes adding up resource allocation demand amounts included in resource information broadcasted by a counterpart device configuring the target link and one or more adjacent transmission devices by a preset Resource Unit (RU), and adjusting self resource information in consideration of resource position information included in the broadcasted resource information and the added resource allocation demand amount and transmitting the adjusted self resource information to the counterpart transmission device.

9. A method of performing distributed scheduling by a transmission device configuring a target link corresponding to one of a plurality of links in a communication network, the method comprising:
-
broadcasting resource information configured for the target link; receiving resource information adjusted by a counterpart reception device configuring the target link; transmitting a pilot signal and data based on the resource information configured for the target link; receiving channel quality information corresponding to the transmitted pilot signal from the counterpart reception device; when data transmission using allocated resources is completed, determining a resource allocation demand amount for a next device to device communication in consideration of the received channel quality information; when the data transmission using the allocated resources is completed, updating a resource allocation start position for the next device to device communication by the received adjusted resource information; and broadcasting resource information including the determined resource allocation demand amount, the updated resource allocation start position, and identification information of a link for performing the next device to device communication. - View Dependent Claims (10, 11, 12, 19)
