Title:
MODULATION AND CODING SCHEME CONFIGURATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/087986
Kind Code:
A1
Abstract:
Disclosed are an MCS configuration method and apparatus, wherein same can make it possible for a UE in a non-RRC connected state, when supporting qam64LowSE, to acquire a higher transmission reliability with a lower spectral efficiency and code rate. The method comprises: a terminal device receiving MCS configuration information, and determining, according to the MCS configuration information, an MCS configuration in an MCS table supported by the terminal device, wherein the MCS configuration information is used for indicating at least one of the following: an MSC configuration in a first MCS table and an MSC configuration in a second MCS table. In the present application, by means of defaulting or configuring or pre-defining the table used for MCS configuration information, a network device may not require any additional configuration indication information to indicate which MCS table is to be used, such that signaling overheads can be saved. Moreover, the network device can configure the MCS configuration in the MCS table corresponding to qam64LowSE without having knowledge of the capabilities of the terminal, such that the terminal device supporting qam64LowSE can acquire a higher transmission reliability with a lower spectral efficiency and code rate.
