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: This application discloses a random access method and a communication apparatus, to resolve a problem in an existing technology that UEs interfere with each other in a random access procedure. In this application, a network device separately configures a random access resource used for random access performed when a TA is invalid and a random access resource used for random access performed when the TA is valid, so that UE with the invalid TA and UE with the valid TA use different random access resources to perform random access, thereby reducing mutual interference between the UEs and improving data transmission efficiency. In addition, in this application, the network device separately configures random access resources used by UEs with different TA accuracy levels to perform random access, so that the UEs with different TA accuracy levels use different random access resources to perform random access.

Abstract: The present disclosure discloses a data processing method, a network device, and a terminal. In this method, a transmit end combines basic modulation symbols obtained after basic modulation is performed on all layers of data, to obtain a combined symbol vector X. The transmit end maps the symbol vector X to Q resource elements to obtain a data vector S. A symbol quantity of the symbol vector X is greater than a symbol quantity of the data vector S. The symbol quantity of the data vector S is Q. Q is a positive integer. Therefore, non-orthogonal spreading and superposition transmission of a plurality of terminals can be implemented in both uplink and downlink, thereby effectively improving transmission efficiency.
