Title:
INFORMATION TRANSMISSION METHOD AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/096220
Kind Code:
A1
Abstract:
Provided in the application are a method and a communication device for information transmission. The method comprises: when it is determined that a higher-layer signaling is not configured with a scrambling code identifier, the communications device scrambles or descrambles data using a second initial scrambling value, wherein the scrambling code identifier is used by the communications device to determine a first initial scrambling value for data scrambling or descrambling. The second initial scrambling value is associated with at least one or at least two of a cell identity, a wireless network temporary identity, and a reserved bit. Therefore, in the embodiment of the present application, when it is determined that the scrambling code identifier is not configured for the higher-layer, the communications device performs scrambling or descrambling processing on the data using the second initial scrambling value. The problem that the terminal device cannot determine the initial scrambling value for data scrambling in the prior art is solved.
