Abstract: A data transmission method and a related device. In the method, a first terminal device receives response information based on received DCI that is associated with SSB information and/or a first identity and that is from a network device. In this way, the first terminal device may learn in advance, based on the received DCI, whether to receive response information scheduled by using the DCI. In other words, the first terminal device may identify, based on the DCI, whether a PDSCH scheduled by using the DCI is response information of the first terminal device, thereby avoiding repeated receiving of unnecessary response information, and reducing power consumption of the first terminal device.

Abstract: An information transmission method includes sending, by a terminal, second information and uplink data. The uplink data is sent in a second access mode. The second information indicates a first access mode. The first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode.

Abstract: A HARQ-ACK transmission method and an apparatus. A network device configures at least two common PUCCH resource sets for a terminal device, and sends, to the terminal device, configuration information indicating the at least two common PUCCH resource sets. After receiving the configuration information from the network device, the terminal device determines, from the at least two common PUCCH resource sets, a first PUCCH resource used to send HARQ-ACK information, and sends the HARQ-ACK information to the network device based on the first PUCCH resource. Available PUCCH frequency domain resources are able to be added for the terminal device in a same slot. PUCCH frequency domain resource collision is reduced, and a transmission delay that is increased to avoid the PUCCH frequency domain resource collision is reduced.
