Abstract: This application provides example communication methods, terminal devices, and network devices. One example method includes configuring, by a network device, a first bandwidth part BP and a second BP for a terminal device. The network device then sends a first TB to the terminal device. When the first BP and the second BP correspond to a same physical parameter, the first TB is mapped onto the first BP and the second BP. When the first BP and the second BP correspond to different physical parameters, the network device further sends a second TB to the terminal device, where the first TB is mapped onto the first BP, and the second TB is mapped onto the second BP.

Abstract: Embodiments of this application provide a method for processing information bits in a wireless communication network. A communication device receives a radio resource control (RRC) signaling, wherein the RRC signaling comprises time window information and time unit format information, wherein the time window information comprises a hybrid automatic repeat request (HARQ) time sequence K1 set, wherein K1 is a time relationship between a time unit of a physical downlink shared channel (PDSCH) and a time unit of a physical uplink control channel (PUCCH), or wherein the K1 is a time relationship between a time unit of a (PDSCH) and a time unit of a physical uplink shared channel (PUSCH). The device determines HARQ feedback information based on the time window information and the time unit format information and sends the HARQ feedback information.

Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method may include detecting, by a network device, a first signal in an uplink signal. The method may also include determining, by the network device, a signal structure of the uplink signal based on a result of detecting the first signal. Furthermore, the method may include receiving, by the network device, the uplink signal based on the signal structure, and/or responding to the uplink signal based on the signal structure. According to the data transmission method in the embodiments of this application, before receiving data, the network device can determine the signal structure, used by the terminal device, of the uplink signal, and then use a corresponding receiving method to avoid complexity and a reliability risk that are caused by completely blind detection performed by the network device.
