Abstract: A communication method includes determining, by a terminal side device in a mobile communications system, N random access preambles on N uplink bandwidth parts (BWPs) in a random access process, where N is an integer greater than or equal to 2, and sending, by the terminal side device, the N random access preambles to a network side device so that the terminal side device can perform random access on a plurality of uplink BWPs. In this method, the network side device or each terminal side device may subsequently perform random access on any one of the N uplink BWPs.

Abstract: This application provides a communication transmission method and a device. The method includes: A terminal device receives first indication information from a network device; and the terminal device skips PDCCH monitoring in a first cell based on the first indication information. The first cell is a single cell; the first cell is a primary cell Pcell; the first cell is a Pcell and at least one Scell of secondary cells Scells in which PDCCH monitoring is skipped when PDCCH monitoring is skipped in the Pcell; or the first cell is a Pcell and all activated Scells of Scells. The method effectively avoids PDCCH-only of the terminal device in the first cell.

Abstract: In certain embodiments, a method includes generating a first signal and a second signal. The first signal includes at least one first sub-signal, and the second signal includes at least one second sub-signal. A subcarrier frequency spacing of the first sub-signal is M times as large as a subcarrier frequency spacing of the second sub-signal. The method further includes separately sending each first sub-signal and each second sub-signal. In a range of a first preset frequency apart from a reference subcarrier frequency, all the second sub-signals sent on a subcarrier corresponding to a subcarrier frequency whose difference from the reference subcarrier frequency is a non-integer multiple of the subcarrier frequency spacing of the first signal are zero signals. The reference subcarrier frequency is a subcarrier frequency of the first sub-signal adjacent to the second signal in a frequency domain.
