Patent Description:
With the continuous development of communication technology, the necessity of extending a PBCH (Physical Broadcast Channel) is becoming stronger and stronger. However, there is no technical solution for extending the PBCH in the related art, which reduces the communication capability of PBCH.

<CIT> discloses a BS determining to transmit a BRS in the first radio frame and sending to the UE an indication indicating a presence of a BRS transmission in the PBCH and/or the repetition of the PBCH (in the 1st synch, subframe), such that the UE may expect to decode a BRS (e.g., from the second synchronization subframe). During the second synchronization subframe of the first radio frame, the base station may use the second synchronization channel to transmit a BRS, a PSS, an SSS, and a repetition of the BRS.

<CIT> provides a method for information transmission, a base station and a user equipment. The method for information transmission includes: performing a coverage enhancement processing on control information and data information; transmitting the control information and the data information, which the coverage enhancement processing is performed on, to a user equipment; and transmitting coverage enhancement indication information to the user equipment, where the coverage enhancement indication information is used for indicating the user equipment to acquire the control information and the data information which the coverage enhancement processing is performed on.

With the continuous development of communication technology, the necessity of extending the PBCH (Physical Broadcast Channel) is becoming stronger and stronger. However, there is no technical solution for extending PBCH in the related art, which reduces the communication capability of PBCH.

In the first version of <NUM> (5th Generation, the fifth generation mobile communication technology) in the 3GPP (3rd Generation Partnership Project), effective information of a PBCH is only <NUM> bits. Considering the first version is relatively hasty, many subsequent extensions are not considered, so the extension of the PBCH is required. On the other hand, 3GPP also clearly stated that forward compatibility and backward compatibility should be considered to increase the practicability of the standard. Therefore, the extension of the PBCH cannot affect the compatibility of the network and the terminal.

In view of the above problems, the present disclosure proposes a method for extending a PBCH. In the method for extending a PBCH, a synchronous broadcast block of the PBCH is provided with a PBCH extension bit first, and then the extension of the PBCH is performed based on the PBCH extension bit. The PBCH extension bit may be one of the above-mentioned "only <NUM> bits of effective information of a PBCH".

In addition, when the extension of the PBCH is performed based on the PBCH extension bit, it can include, but not limited to, the following three situations.

The first situation is that the extension of the PBCH is required, and the sending of the PBCH extension information is required.

In this case, the base station can enable an indication function for the PBCH extension bit, when the extension of the PBCH is required. The PBCH extension bit is configured to indicate whether there is PBCH extension information. When the sending of the PBCH extension information is required, the base station may set the PBCH extension bit in a first synchronous broadcast block to be a first state, and the first state is configured to indicate that there is PBCH extension information. The base station sends the first synchronous broadcast block to a terminal, so that the terminal determines that there is the PBCH extension information according to the first state. A PBCH extension block is generated, and the PBCH extension block includes the PBCH extension information; and the PBCH extension block is sent at a set extension position, so that the terminal receives the PBCH extension block at the set extension position, and obtains the PBCH extension information from the PBCH extension block.

The second situation is that the extension of the PBCH is required, and the sending of the PBCH extension information is not required for the moment.

In this case, the base station can enable an indication function for the PBCH extension bit, when the extension of the PBCH is required. The PBCH extension bit is configured to indicate whether there is PBCH extension information. When the sending of the PBCH extension information is not required, the base station may set the PBCH extension bit in the second synchronous broadcast block to be a second state, and the second state is configured to indicate that there is no PBCH extension information, and the second synchronous broadcast block is sent to the terminal, so that the terminal determines that there is no PBCH extension information according to the second state.

The third situation is that the extension of the PBCH is not required.

In this case, the base station can disable the indication function for the PBCH extension bit when the extension of the PBCH is not required, and sets a PBCH extension bit in a third synchronous broadcast block to be a reserved state which is configured to indicate to ignore the PBCH extension bit; and sends the third synchronous broadcast block to the terminal, so that the terminal determines to ignore the PBCH extension bit according to the reserved state.

Therefore, the present disclosure implements the extension of the PBCH by setting the PBCH extension bit, thereby solving the compatibility problem of different terminals and improving the practicability of PBCH extension.

The following describes the technical solutions provided by the embodiments of the present disclosure with specific embodiments.

In the embodiment of the present disclosure, the set extension position may be a predefined extension position, and both the base station and the terminal may know the set extension position in advance.

In an embodiment, the set extension position is a specified time domain position after the first synchronous broadcast block.

For example, as shown in <FIG>, the sending period of the synchronous broadcast block is <NUM>.

The PBCH extension bit is used to indicate whether there is PBCH extension information. When the sending of the PBCH extension information is required, the base station may set the PBCH extension bit in the first synchronous broadcast block to be the first state which is configured to indicate that there is PBCH extension information, and send the first synchronous broadcast block to the terminal, so that the terminal may determine that there is the PBCH extension information according to the first state.

Claim 1:
A method for extending a physical broadcast channel PBCH, wherein the method is performed by a base station, and a synchronous broadcast block of the PBCH is provided with a PBCH extension bit, and the method comprises:
enabling (<NUM>) an indication function for the PBCH extension bit when extension of the PBCH is required, wherein the PBCH extension bit is configured to indicate whether there is PBCH extension information;
setting (<NUM>) a PBCH extension bit in a first synchronous broadcast block to be a first state when sending of the PBCH extension information is required, wherein the first state is configured to indicate that there is PBCH extension information;
sending (<NUM>) the first synchronous broadcast block to a terminal, so that the terminal determines that there is the PBCH extension information according to the first state;
generating (<NUM>) a PBCH extension block, wherein the PBCH extension block comprises the PBCH extension information; and
sending (<NUM>) the PBCH extension block at a set extension position, so that the terminal receives the PBCH extension block at the set extension position, and obtains the PBCH extension information from the PBCH extension block,
wherein the method further comprises:
disabling (<NUM>) the indication function for the PBCH extension bit when the extension of the PBCH is not required;
setting (<NUM>) a PBCH extension bit in a third synchronous broadcast block to be a reserved state, wherein the reserved state is configured to indicate to ignore the PBCH extension bit; and
sending (<NUM>) the third synchronous broadcast block to the terminal, so that the terminal determines to ignore the PBCH extension bit according to the reserved state.
