Abstract: A downlink transmission method includes determining a time domain position of at least one first transmission resource in resources of a downlink data channel. When the at least one first transmission resource is a plurality of first transmission resources, start positions of time domain positions of the plurality of first transmission resources are the same. The at least one first transmission resource can be used to transmit downlink control information. The method also includes determining, based on the time domain position of the at least one first transmission resource and time domain positions of the resources of the downlink data channel, a condition satisfied by the at least one first transmission resource. The method further includes determining a transmission mode of the downlink control information and/or the downlink data channel in the resources of the downlink data channel based on the condition.

Abstract: This application provides a reference signal generation method, a reference signal detection method, and a communications apparatus, so that a terminal device or a network device can generate a reference signal by using a pseudo-random sequence initial factor cinit provided in embodiments of this application. Compared with a solution in the current technology, the generation manner can support a relatively large quantity of reference signal sequences, to better meet requirements of a plurality of 5G scenarios. The method may include: obtaining a reference signal sequence based on a pseudo-random sequence initial factor cinit; and mapping the sequence to one or more OFDM symbols, where the pseudo-random sequence initial factor cinit is related to a parameter d, d max(log2(nID,max+1)−10,0) or d=max(log2 (nID,max+1)−12,0), max represents that a larger value is selected from two values, and nID,max represents a maximum value of a reference signal sequence ID.

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.
