摘要： A signal scrambling method and apparatus, and a signal descrambling method and apparatus are disclosed. In the signal scrambling method, a communications apparatus scrambles a signal by using a scrambling sequence, and sends the scrambled signal. In the signal descrambling method, a communications apparatus receives a signal, and descrambles the signal by using a scrambling sequence. An initial value of the scrambling sequence is determined based on a time unit number corresponding to a frame structure parameter used for transmitting the signal, so that different scrambling sequences can be used to scramble signals that are transmitted by using different frame structure parameters. Therefore, interference randomization can be implemented for signal scrambling, and this can be applicable to various application scenarios in 5G NR to improve performance.

摘要： Embodiments of this application disclose a time domain resource allocation method. The method may include: determining N pieces of candidate time domain resource information, where N is greater than or equal to 2; and receiving indication information, where the indication information is to be used to determine, from the N pieces of candidate time domain resource information, a time domain resource allocated to a data channel. For at least one of M frame structure parameters, a time domain resource indicated by at least one of the N pieces of candidate time domain resource information is different from a time domain resource used by at least one of the following signals and/or channels in LTE: a cell-specific reference signal (CRS), a physical downlink control channel (PDCCH), a multimedia broadcast single frequency network (MBSFN), a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and/or a physical broadcast channel (PBCH).

摘要： This disclosure provides an information transmission method and a communications device. The method includes: when determining that higher layer signaling is not configured with a scrambling identifier, scrambling or descrambling, by a communications device, data by using a second initial scrambling value, where the scrambling identifier is used by the communications device to determine a first initial scrambling value used for data scrambling or descrambling, and the second initial scrambling value is related to at least one or two of a cell identifier, a radio network temporary identifier, and a reserved bit. Therefore, in the embodiments of this disclosure, when determining that the higher layer is not configured with the scrambling identifier, the communications device scrambles or descrambles the data by using the second initial scrambling value. This resolves a problem in the prior art that a terminal device cannot determine an initial scrambling value used for data scrambling.
