Title:
INFORMATION INDICATING METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/157670
Kind Code:
A1
Abstract:
Embodiments of the present invention disclose an information indicating method and a related device. The method comprises: determining a frequency resource of a PUSCH needing to be indicated by downlink control information (DCI); if the number of PRBs comprised in the frequency resource of the PUSCH is greater than or equal to one, determining that three bits in the DCI are to be used to indicate a HARQ process ID, two bits are to be used to indicate an RV, and two bits are to be used to indicate a TPC command of the PUSCH; if the number of subcarriers comprised in the frequency resource of the PUSCH is less than 12, determining that the number of bits in the DCI to be used to indicate the HARQ process ID is less than three, and/or one bit in the DCI is to be used to indicate the RV, and/or 0 bits in the DCI are to be used to indicate the TPC command of the PUSCH; determining the DCI; and sending the DCI to a terminal device. Implementation of the embodiments of the present application helps reduce the number of bits in DCI.
