Title:
METHOD AND APPARATUS FOR INDICATING NUMBER OF REPEATED TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2021/120024
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Disclosed are a method and apparatus for indicating the number of repeated transmissions, wherein same are used to implement the configuration of the number of repeated transmissions of an SRS and/or a PUSCH so as to better adapt to a channel change. The method comprises: a network device sending DCI to a terminal device, wherein the DCI includes first indication information, and the first indication information is used to indicate the number of repeated transmissions of an SRS and/or a PUSCH. Since DCI has a faster update process than RRC signaling and smaller overheads, a network side device can flexibly configure the number of repeated transmissions of an SRS and/or a PUSCH by means of the DCI, so as to better adapt to a channel change and further improve the channel estimation capability and the signal demodulation performance.
