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: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Abstract: A communication method comprises that a user equipment receives quantity information, sent by a transmission reception point TRP, of control information to be sent to the user equipment. N pieces of control information are to be sent to the user equipment, and N is an integer greater than or equal to 1. The user equipment determines, based on the quantity information, that the N pieces of control information need to be detected; and the user equipment detects the N pieces of control information. In an embodiment, processing complexity of the TRP and processing complexity of the user equipment can be reduced in a control information obtaining process.
