TECHNICAL FIELD

The present disclosure relates to the field of communication technologies, and more particularly, to a method for receiving a synchronization block, an apparatus for receiving a synchronization block, a method for transmitting system information, an apparatus for transmitting system information, an electronic device, and a computer readable storage medium.

BACKGROUND

At present, in a standardization process of 5G (Fifth Generation Mobile Communication Technology) of the 3GPP (3rd Generation Partnership Project), a synchronization block is mainly transmitted by means of beam scanning, and a synchronization signal and a physical broadcast channel are carried by the synchronization block.

User equipment needs to perform synchronized-block-based measurement according to the configuration of the system. In addition to measuring the synchronization signal in the synchronization block of the own cell, it is also necessary to measure a synchronization signal in a synchronization block of another cell. In order to measure the synchronization signal in the synchronization block of another cell, it is necessary to determine the time information of receiving the synchronization block of another cell.

wherein the processor is configured to:

transmit system information to user equipment, where the system information includes indication information, and the indication information is used to indicate whether a first cell where the user equipment is located and a second cell which sent the system information belong to a synchronous system.

According to a seventh aspect of the embodiments of the present disclosure, there is provided a computer readable storage medium having stored thereon a computer program, wherein the program, when executed by a processor, implements steps of:

receiving system information of a first cell, where the system information includes indication information;

determining, according to the indication information, whether the first cell and N second cells adjacent to the first cell belong to a synchronous system, where N is an integer greater than or equal to 1; and

According to an eighth aspect of the embodiments of the present disclosure, there is provided a computer readable storage medium having stored thereon a computer program, wherein the program, when executed by a processor, implements a step of:

transmitting system information to user equipment, where the system information includes indication information, and the indication information is used to indicate whether a first cell where the user equipment is located and a second cell which sent the system information, belong to a synchronous system.

The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects.

It can be seen from the above embodiments that, when it is determined that the first cell and the N second cells belong to the synchronous system, since the user is currently in the first cell, it is possible to determine the time for receiving the synchronization block of the first cell. Then, when the time for receiving the synchronization block sent by the first cell and the time for receiving the synchronization block sent by the second cell are in the same time period in one cycle, the synchronization block of the second cell can be received at the time for receiving the synchronization block of the first cell. When there is a specific time difference between the time for receiving the synchronization block sent by the first cell and the time for receiving the synchronization block sent by the second cell, the synchronization block of the second cell can be received at a time delayed or advanced a specific time from the time for receiving the synchronization block of the first cell.

In the process of receiving the synchronization block of the second cell in the embodiments of the present disclosure, it is not necessary to parse the system information of the second cell, so that the time for receiving the synchronization block of the second cell can be determined more quickly, thereby receiving the synchronization block more quickly. In turn, the synchronization information in the synchronization block can be acquired more quickly, so that the user equipment can quickly complete the handover of the cell.

It should be understood that both the above general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.
