256 QAM-BASED RESOURCE ALLOCATION METHOD AND BASE STATION THEREOF

Title:

256 QAM-BASED RESOURCE ALLOCATION METHOD AND BASE STATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2015/147442

Kind Code:

A1

Abstract:

One embodiment of the present specification provides a method for allocating resources to user equipment (UE) supporting 256 quadrature amplitude modulation (QAM) demodulation. The resource allocation method can comprise the steps of: receiving a channel quality information (CQI) report from the UE; determining, by the UE, whether a backoff of transmission power has been applied to a downlink subframe from which CQI is measured; determining whether the backoff of the transmission power is to be applied to the downlink subframe which is supposed to allocate the resources; and determining a modulation coding scheme (MCS) level on the basis of the CQI and the results of the determination.
