AI Technical Summary

Technical Problem

Traditional DRX mechanisms do not take into account the fault tolerance of communication systems, resulting in unnecessary power consumption for the UE during data transmission.

Method used

The terminal receives DRX configuration information sent by the network device and sets the running state of the DRX timer according to the fault tolerance information, including fault tolerance capability, threshold and mode information, so as to set the timer to non-running state when there is no need to retransmit erroneous data or transmit the remaining data, thereby reducing unnecessary PDCCH detection.

Benefits of technology

By adjusting the operating state of the DRX timer, the power consumption of the terminal can be reduced, and communication efficiency and accuracy can be improved.

Abstract

A communication method and a related communication apparatus. The method comprises: a terminal receives DRX configuration information from a network device, the DRX configuration information being used for configuring parameters of a DRX timer; and the terminal sets an operating state of the DRX timer on the basis of fault tolerance information or indication information from the network device. The fault tolerance information comprises at least one of fault tolerance capability information, fault tolerance threshold information, or fault tolerance mode information. The fault tolerance capability information indicates that data transmission has a fault tolerance capability, the fault tolerance threshold information indicates the amount of data allowed to be erroneously transmitted, and the fault tolerance mode information indicates a data mode in which erroneous transmission is allowed. The indication information sent by the network device is related to the fault tolerance information. The terminal can set the operating state of the DRX timer on the basis of data fault tolerance information, and when the terminal does not need to retransmit erroneous data or does not need to transmit redundant data, the corresponding DRX timer is set to a non-operating state, so that the terminal does not need to continue to perform PDCCH detection, thereby reducing the power consumption of the terminal.
