Problems solved by technology

[0003] However, the existing protocol does not specify the specific bearer method of the time index in the PBCH in the 5G system. Correspondingly, the user equipment side cannot accurately and quickly obtain the required time index based on PBCH detection.

Embodiment Construction

[0021] In a fifth-generation mobile communication technology (5th-Generation, 5G for short) system, a Physical Broadcast Channel (Physical Broadcast Channel, PBCH for short) will be included in a synchronization signal block for transmission. The PBCH may be used to carry part of minimum system information (Minimum System Information, MSI for short), and may also be used to carry synchronization signal block index (SS-block index) information.

[0022] Based on the existing protocol, the time-domain positions of the possible synchronization signal blocks in one cycle are fixed, so when the user equipment (User Equipment, referred to as UE) detects the index information of the synchronization signal block, it can deduce the Timing information within the period (for example, the timing information may include which time slot within the period the synchronization signal block starts and which symbol within the time slot).

[0023] For example, when the period is 10 milliseconds, ...

Abstract

A time index bearing method, detection method and device, storage medium, base station, terminal, the bearing method includes: encoding the information bits carried on the actually transmitted PBCH block, wherein the information bits include the first time index, the first time index includes at least a part of information in the system frame number information; the coded information bits are scrambled based on the actually transmitted scrambling code subsequence, wherein the actually transmitted scrambling code subsequence is from the preset scrambling code subsequence selected from the code subsequence set. The technical solution provided by the present invention can ensure that the PBCH designed by the base station in the 5G system can support one detection and multiple detections.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, relates to a time index bearing method, detection method and device, storage medium, base station, and terminal. Background technique [0002] In a fifth-generation mobile communication technology (5th-Generation, 5G for short) system, a Physical Broadcast Channel (Physical Broadcast Channel, PBCH for short) will be included in a synchronization signal block for transmission. The physical broadcast channel can be used to carry part of the minimum system information (Minimum System Information, MSI for short), and can also be used to carry the index (SS-block index) information of the synchronization signal block, and part or all of the system frame number ( System Frame Number, referred to as SFN) information. Wherein, the index information of the synchronization signal block and the system frame number information may be collectively referred to as a time ind...
