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

The invention provides a time index carrying method and apparatus, a time index detection method and apparatus, a storage medium, a base station and a terminal. The carrying method comprises the following steps: encoding an information bit carried on a PBCH block that is actually transmitted, wherein the information bit comprises a first time index, and the first time index comprises at least a part of information in system frame number information; and scrambling the encoded information bit based on an actually transmitted scrambling code sub-sequence, wherein the actually transmitted scrambling code sub-sequence is selected from a preset scrambling code sub-sequence set. By adoption of the technical scheme provided by the invention, it can be ensure that a PBCH designed by the base station in a 5G system can support once detection and multiple times of detection.

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...
