摘要： The disclosure provides an information transmission method and apparatus. The method includes: carrying a first parameter in physical layer signaling corresponding to a Physical Downlink Shared Channel (PDSCH); and transmitting, according to an indication of the first parameter, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH, which may be specifically identifying an indication meaning of the current first parameter on a predetermined basis and selecting which positions are used to transmit the HARQ-ACK. By adopting the above solution, a first communication node itself sets a position at which an HARQ-ACK is transmitted, and a second communication node feeds back, according to an indication, the HARQ-ACK corresponding to a PDSCH in time, thereby solving the problem of greater delay for HARQ-ACK feedback in the related art, and ensuring the low delay processing of a service.

摘要： The present invention relates to the field of wireless communications. Disclosed are a method and apparatus for sending a sounding reference signal. The method comprises: contending for a use permission of an unlicensed carrier according to listen-before-talk (LBT) or clear channel assessment (CCA) detection; and when the use permission of the unlicensed carrier is successfully contended, sending a sounding reference signal (SRS) on the unlicensed carrier. A method for transmitting an SRS and a PUSCH simultaneously or not simultaneously and a method for sending SRSs at part of uplink subframes are provided, and more SRS sending opportunities are provided. In downlink transmission, an SRS sequence is used as an occupied signal, thereby simplifying design of the occupied signal.
