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: The application provides a data sending method and a communication apparatus to avoid signaling overheads caused by scheduling by a network device, and a terminal device can flexibly select a quantity of repeated transmissions based on an actual situation, so that data transmission performance is improved. The network device sends configuration information of a receive power to the terminal device. After receiving the configuration information of the receive power, the terminal device determines a quantity of repeated transmissions of target data based on the configuration information of the receive power. After determining the quantity of repeated transmissions of the target data, the terminal device sends the target data to the network device based on the quantity of repeated transmissions of the target data.

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.

Abstract: This application provides a random access method and an apparatus. The random access method includes: User equipment sends a random access message of a first-type random access procedure to a network device. The random access message of the first-type random access procedure includes a random access preamble and uplink data. The user equipment starts a first time window after transmission of the random access preamble ends, and detects first downlink control information DCI and second DCI within the first time window. The first DCI is used to schedule a first physical downlink shared channel PDSCH that carries a first response message for the random access preamble, and the second DCI is used to schedule a second PDSCH that carries a second response message for the random access message.
