Abstract: A communication method and apparatus. A terminal device determines channel state information based on S indexes of S vectors. Each of the S vectors is included in a first vector quantization dictionary. The first vector quantization dictionary includes N1 vectors, where N1 and S are both positive integers. The terminal device sends the channel state information to a network device. Because a vector included in the vector quantization dictionary usually has a relatively large dimension, quantizing channel information by using the first vector quantization dictionary is equivalent to performing dimension expansion on the channel information or maintaining a relatively high dimension. High-precision feedback is implemented by using relatively low signaling overheads.

Abstract: This application discloses a method. The method includes: A terminal device obtains one or more measurement results respectively corresponding to one or more reference signals, and determines a CEL of the terminal device based on the one or more measurement results and at least one of N thresholds, where the N thresholds are a threshold 0, a threshold 1, . . . , and a threshold (N−1) in descending order. If there is a measurement result greater than or equal to the threshold 0 in the one or more measurement results, the CEL of the terminal device is a CEL 0. If the one or more measurement results are less than a threshold i, and there is a measurement result greater than or equal to a threshold (i+1), the CEL of the terminal device is a CEL (i+1), and a value of i is an integer from 0 to (N−2).

Abstract: An information transmission method includes sending, by a terminal, second information and uplink data. The uplink data is sent in a second access mode. The second information indicates a first access mode. The first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode.

Abstract: Embodiments of the present invention describe a data transmission method, a related device, and a system. The method may include sending, by a terminal, uplink data to a network device. The uplink data is scrambled by using a scrambling sequence, and the scrambling sequence is generated based on information about a radio resource used by the terminal to send the uplink data. According to the embodiments of the present invention, it can be ensured that scrambling and descrambling on the uplink data are successfully implemented when the network device does not obtain an identifier of the terminal in a cell.
