METHOD AND DEVICE FOR INDICATING MODULATION AND CODING SCHEME, AND METHOD AND DEVICE FOR RECEIVING DOWNLINK DATA

摘要

The present disclosure provides a method for indicating a modulation and coding scheme (MCS), including a step of when it is determined that a UE supports a downlink 256QAM mode, indicating the 256QAM mode using current information indicating the MCS or extended information indicating the MCS in downlink control information (DCI). The present disclosure further provides a method for receiving downlink data, including a step of, after a UE has received information indicating an MCS which includes indication information indicating a 256QAM mode, receiving the downlink data according to the 256QAM mode and a corresponding TBS index. The present disclosure further provides devices for implementing the above methods.

1. A method for indicating a modulation and coding scheme (MCS), comprising a step of:
when it is determined that a user equipment (UE) supports a downlink 256QAM mode, indicating the 256QAM mode using current information indicating the MCS or extended information indicating the MCS in downlink control information (DCI).
