Methods and devices for information transmission

Abstract

The application provides a methods and devices for information transmission. The method includes that a terminal device receives control signaling sent by a network device at a first time position; and the terminal device sends a Scheduling Request (SR) and/or feedback information related to the control signaling to the network device according to the first time position, a second time position for sending the SR being at least partially overlapped with a third time position for sending the feedback information. The terminal device determines how to effectively transmit the information related to the control signaling and other information on the basis of time when the downlink control signaling is received, so that different information may still be effectively transmitted under the situation that Physical Uplink Control Channels (PUCCHs) of two different lengths exist.
