Problems solved by technology

In the related art, for the URLLC service, a radio resource control (Radio Resource Control, RRC) parameter is introduced to configure a new radio network temporary identity (RadioNetwork Tempory Identity, RNTI), when a new RNTI (new RNTI) is configured , if the cyclic redundancy check code (Cyclic RedundancyCheck, CRC) of the downlink control information (DownlinkControlInformation, DCI) is scrambled by the new RNTI, the physical downlink shared channel (Physical DownlinkShared Channel, PDSCH) scheduled by the DCI adopts the new 64QAM MCS table; if the CRC of the DCI is scrambled by the existing RNTI (existing C-RNTI), the PDSCH scheduled by the DCI uses the MCS table indicated by the RRC signaling. However, when the MCS table indicated by the RRC signaling is For the new 64QAM table, the new RNTI and the existing RNTI correspond to the same MCS table, and the function of distinguishing MCS through RNTI is lost

Abstract

An embodiment of the invention provides an MCS configuration method and device, terminal equipment and network equipment, which can improve the indication efficiency of an MCS. The MCS configuration method comprises the steps that: the terminal equipment receives a first RRC signaling sent by the network equipment, the first RRC signaling carries first indication information, and the first indication information is used for indicating a type of an MCS table, wherein under the condition that a first RNTI is configured, the type of the MCS table indicated by the first indication information doesnot include a first MCS table, and the first MCS table refers to a MCS table corresponding to the first DCI under the condition that CRC of the first DCI is scrambled by the first RNTI.

Description

technical field [0001] The embodiment of the present application relates to the technical field of mobile communication, and specifically relates to an MCS configuration method and device, a terminal device, and a network device. Background technique [0002] In order to meet people's pursuit of business speed, delay, high-speed mobility, and energy efficiency, as well as the diversity and complexity of business in future life, the International Standards Organization of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) began to develop the first Five generations (5 th Generation, 5G) mobile communication technology. [0003] The Ultra-Reliable Low Latency Communication (URLLC) service is introduced into the 5G system, which is characterized by ultra-high reliability (for example, 99.999%) within an extreme delay (for example, 1ms) transmission. In order to achieve this goal, a lower bit rate transmission is introduced to improve the relia...
