Abstract: The time-frequency resources of a particular numerology may be used to transmit OFDM symbols that have a cyclic prefix that is longer than the cyclic prefix of other OFDM symbols. This may complicate alignment across different numerologies. Time-frequency resource partitions are disclosed herein that may assist in symbol alignment and/or subframe alignment across the different numerologies.

Abstract: 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.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting broadcast-multicast single-frequency network measurement data, where second measurement data is acquired by preprocessing acquired first measurement data, and the second measurement data is sent to a base station. Because the second measurement data is obtained after the first measurement data is preprocessed, a size of the second measurement data is smaller than that of the first measurement data, thereby reducing a transmission overhead.

Abstract: A frequency hopping processing method and apparatus are disclosed, where user equipment receives frequency hopping information, which is sent by a network device, of an extended transmission time interval (TTI); and determines a frequency hopping area of the extended TTI according to the frequency hopping information of the extended TTI. The frequency hopping area of the extended TTI and a frequency hopping area of a normal TTI do not overlap in frequency, and during M-PUSCH frequency hopping of each extended TTI, the user equipment can hop into a corresponding M-PUSCH frequency hopping area according to a preset frequency hopping pattern, and does not hop into a PUSCH frequency hopping area, so that a resource conflict does not exist when M-PUSCH frequency hopping of an extended TTI and PUSCH frequency hopping of a 1 ms TTI are performed at the same time.
