Abstract

The embodiment of the invention provides an MCS index table configuration method, a user terminal and network side equipment, and the method comprises the steps that the user terminal receives a downlink message sent by the network side equipment, and the downlink message is used for indicating an MCS index table adopted by a service channel of the user terminal; And the user terminal transmits the service channel by adopting the MCS index table indicated by the downlink message. According to the embodiment of the invention, the flexibility of sending and receiving data by the user terminal can be improved, and the configuration delay is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a modulation and coding scheme (Modulation and Coding Scheme, MCS) index table configuration method, a user terminal and a network side device. Background technique [0002] In the current communication system, the user terminal determines the modulation and coding of uplink data and the demodulation and decoding of downlink data through the MCS. Among them, the MCS index table is often statically configured. However, different services are supported in the 5G system, such as enhanced Mobile Broadband (eMBB) and UltraReliable Low Latency Communication (URLLC). Although the user terminal can support a variety of service data, since the current MCS index table is statically or semi-statically configured by Radio Resource Control (RRC) signaling, the user terminal has poor flexibility in receiving and sending data. The configuration delay is long. Contents of th...
