Problems solved by technology

However, after the network device will send the instruction to use the MCS mapping table corresponding to 256QAM to the UE, it will take a period of time for the terminal device to complete the configuration of 256QAM, and the network device will not be able to determine that the UE has completed the configuration of 256QAM until it receives the configuration completion message sent by the UE. configuration, but in the prior art, the network device receives the PUSCH sent by the terminal device during this period of time, because the network device will use the MCS mapping table supporting 256QAM to demodulate the PUSCH, but the terminal device does not necessarily complete the 256QAM configuration Therefore, the network equipment will fail to demodulate, which will lead to PUSCH error codes, and even UE drop calls

Abstract

The application discloses a data processing method, network equipment and terminal equipment, which can prevent the network equipment from demodulation failure because the terminal equipment has not completed 256QAM configuration. The method of this application includes: if the network device does not receive the instruction sent by the terminal device instructing the terminal device to confirm the use of the first mapping table, the network device sends an instruction including the target MCS index to the terminal device, wherein the target MCS index supports 256QAM and The corresponding modulation scheme in the MCS mapping table that does not support 256QAM is the same as the TBS index of the transport block size.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data processing method, network equipment and terminal equipment. Background technique [0002] High-order modulation technology is a technology introduced to increase the amount of transmitted data without increasing the transmission bandwidth. Under the long-term evolution (long time evolution, LTE) technology, the highest order of a common high-order modulation technology is 64-order quadrature amplitude modulation (quadrature amplitude modulation, 64QAM). With the development of technology, 256QAM has a theoretical gain of 33% relative to 64QAM, because in a 256QAM scenario, each resource element (resource element, RE) can carry 8 bits of data. In the 64QAM scenario, each RE can only carry 6 bits of data. Therefore, in the same RE scenario, the amount of data that can be transmitted by 256QAM is 33% higher than that of 64QAM. [0003] According to the...
