AI Technical Summary

Technical Problem

The existing NR protocol's RRC signaling for configuring the number of repetitions of SRS and PUSCH is slow, leading to poor channel estimation and signal demodulation performance due to its inability to dynamically adapt to channel changes.

Method used

The method involves using DCI to dynamically indicate the number of repetitions of SRS and/or PUSCH, allowing for faster updates and better adaptation to channel changes, with the terminal determining the number based on indication information in the DCI, which includes using existing or extension fields, and optionally triggered by additional signaling.

Benefits of technology

This approach enhances channel estimation capability and signal demodulation performance by enabling more adaptive configuration of SRS and PUSCH repetitions, improving the efficiency and reliability of uplink data transmission.

Abstract

This application relates to the field of communications technologies, and discloses a method and an apparatus for indicating a number of repetitions, so that a configuration of a number of repetitions of an SRS and / or a PUSCH is more adaptive to a channel change. The method includes: A network device sends DCI to a terminal device, where the DCI includes first indication information, and the first indication information indicates a number of repetitions of an SRS and / or a PUSCH. Because the DCI has a faster update process than RRC signaling, and overheads are smaller than those of the RRC signaling, the network side device may flexibly configure the number of repetitions of the SRS and / or the PUSCH by using the DCI, to better adapt to the channel change, and further improve a channel estimation capability and signal demodulation performance.
