Abstract: 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.

Abstract: Embodiments of this application disclose a communication method, and a related device and system. The method includes: receiving, by a reception point, first indication information, where the first indication information is used to indicate a time-frequency resource location of a first demodulation reference signal of first data; receiving, by the reception point, second indication information, where the second indication information is used to indicate a time-frequency resource location of a second demodulation reference signal; and determining, by the reception point, a time-frequency resource location of the first data based on the time-frequency resource location of the second demodulation reference signal, and demodulating the first data based on the first demodulation reference signal. Receiving performance of the reception point can be improved. On the premise that a resource conflict does not occur, two base stations communicate with a terminal device by using a time-frequency resource allocated by a second base station.

Abstract: Example channel transmission methods and apparatus are described. One example method includes determining search spaces of at least two downlink control channels by a first network device. The first network device separately determines in the search spaces resources occupied by the at least two downlink control channels. Resource scheduled by the at least two downlink control channels belong to one carrier. The first network device obtains the at least two downlink control channels by using the resources. With the embodiments of the present invention, data on one carrier can be scheduled through a plurality of downlink control channels.
