Title:
APPARATUS AND METHOD FOR UPLINK SCHEDULING IN TDD CELLULAR NETWORK
Document Type and Number:
WIPO Patent Application WO/2018/139714
Kind Code:
A1
Abstract:
Disclosed is an uplink scheduling scheme which calculates a signal to maximum interference ratio by using only one interference signal with the greatest strength from among interference signals transmitted to a plurality of base stations adjacent to a terminal, and performs uplink scheduling on the basis of the signal to maximum interference ratio. The disclosed uplink scheduling scheme accurately estimates the strength of an interference signal transmitted to a base station adjacent to a terminal by using symmetry between an uplink and a downlink, and performs uplink scheduling by using the same so that intercell interference may significantly be reduced from the uplink by performing effective scheduling only with a simple calculation.
