Problems solved by technology

[0005] However, in different application scenarios, the above two methods of transmitting the index information of the synchronization signal block have their own advantages and disadvantages
When the PBCH load is used to carry the index information of the synchronization signal block, channel coding is used to protect the index information of the synchronization signal block. The detection performance of the index information of the synchronization signal block is better, but because the user equipment needs to decode the PBCH, the complexity is high
Using PBCH DMRS to carry the index information of the synchronization signal block is easily affected by inter-cell interference, and the detection performance of the index information of the synchronization signal block is relatively poor, but the complexity is relatively low

Embodiment Construction

[0059] The PBCH is used to bear part of the minimum system information. In the 5G system, broadcast system information is divided into two categories, one is minimum system information (Minimum System Information, MSI), and the other is other system information (Other System Information, OSI). The MSI is sent to the user equipment through broadcasting, while the OSI is generally sent to the user equipment through unicast upon user request. Therefore, MSI can be sent in PBCH. PBCH is generally limited by the number of resources, resulting in a small number of bits that can be carried. In the LTE system, only 24 information bits can be carried. Therefore, only part of the MSI can be sent in the PBCH. In general, part of the MSI information will be carried in the PBCH.

[0060] The PBCH can also be used to carry index (SS-block index) information of a synchronization signal block. Since the time-domain positions of possible sync signal blocks in a certain period are fixed, whe...

Abstract

The invention relates to a time index indication method, a base station, a storage medium and an electronic device. The time index indication method includes the following steps that: subcarrier spacing is acquired; the number of time slots of a synchronization signal burst corresponding to the subcarrier spacing is set according to the subcarrier spacing; and PBCH DMRSs are set according to the subcarrier spacing, and the number of symbols included in the time slots of the synchronization signal burst corresponding to the subcarrier spacing so as to indicate the number of bits of a synchronization signal block index in the synchronization signal burst, and PBCH load is set according to the subcarrier spacing, and the number of the symbols included in the time slots of the synchronizationsignal burst corresponding to the subcarrier spacing so as to indicate the number of bits of a synchronization signal burst index in a synchronization signal burst set. With the time index indicationmethod provided by the above technical schemes of the invention adopted, the detection performance and complexity of the index information of synchronization signal blocks can be well balanced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a time index indicating method, base station, storage medium and electronic equipment. Background technique [0002] In the 5G system, the Synchronization Signal Block (Synchronization Signal Block) includes Primary Synchronization Signal (PSS), Secondary Synchronization Signal (Secondary Synchronization Signal, SSS) and Physical Broadcast Channel (Physical Broadcast Channel, PBCH). Multiple sync signal blocks form a sync signal burst (SS-burst). The synchronization signal burst can be regarded as a relatively concentrated piece of resource including multiple beams. Multiple synchronization signal bursts form a synchronization signal burst set (SS-burst-set). Repeated transmission of synchronization signal blocks on different beams is a process of beam scanning. Through beam scanning training, user equipment (User Equipment, UE) can perceive which beam receives the stronge...
