Abstract: A communication method and a communications apparatus are provided. The communication method includes: receiving a first message from a shared channel of a plurality of network slices, where the first message includes a plurality of network IDs, and the plurality of network IDs are in a one-to-one correspondence with the plurality of network slices; selecting a target network slice from the plurality of network slices; and obtaining access configuration information of the target network slice from network configuration information, and accessing the target network slice based on the access configuration information of the target network slice, where the network configuration information includes a network ID of each of the plurality of network slices and the access configuration information of the target network slice.

Abstract: A data transmission method in the present application includes: determining, by first UE, a frame structure in a time unit, where the frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, according to the data transmission method and the user equipment in embodiments of the present application, a frame structure in a time unit is determined. The frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, when an NB-IOT system is deployed in an LTE system in an embedded manner, and when NB-IOT UE is sending data, a channel resource of the legacy LTE system can be adequately utilized, and a conflict with a legacy LTE SRS can be avoided.

Abstract: The present invention relates to the field of wireless communications technologies. In a receiving device, a receiving module receives a synchronization signal including a first signal and a second signal. The first signal includes N1 generalized ZC sequences, and the second signal includes N2 generalized ZC sequences. The second signal is used to distinguish different cells or different cell groups. There are at least two generalized ZC sequences with different root indexes in (N1+N2) generalized ZC sequences. A processing module performs a first sliding correlation operation and a second sliding correlation operation on the synchronization signal, and performs symbol timing synchronization according to a relationship between a sliding correlation peak generated when a sliding correlation is performed on the N1 generalized ZC sequences and a sliding correlation peak generated when a sliding correlation is performed on the N2 generalized ZC sequences.

Abstract: The present disclosure relates to the field of mobile communication, and in particular, to frequency determining technologies in the field of wireless communication. In a frequency determining method, a base station determines a frequency according to different modes, so that an interval between the frequency and a channel raster is not greater than a particular threshold. Corresponding frequencies are determined by setting different thresholds. According to the technical solutions provided in this application, user equipment may determine, in different modes, a corresponding frequency resource to communicate with a base station.

Abstract: The present disclosure relates to the mobile communications field, and in particular, to a synchronization signal sending method. A network device obtains a first signal after performing discrete Fourier transform (DFT) and orthogonal frequency division multiplexing (OFDM) modulation, or OFDM modulation on a Zadoff-Chu (ZC) sequence whose root index is 1. The network device obtains a second signal after performing DFT and OFDM modulation, or OFDM modulation on a conjugate sequence of the ZC sequence whose root index is 1. The network device generates a synchronization signal, where the synchronization signal includes the first signal and the second signal. The network device sends the synchronization signal to a terminal device.
