Abstract

Embodiments of the present disclosure disclose a message broadcast method, a base station, and user equipment. The message broadcast method includes: determining, by a base station, a piece of system subgroup information of system information of a first cell, where each piece of system subgroup information includes system information content that is applied to a user equipment group that corresponds to the system subgroup information. The method also includes broadcasting, to the user equipment group, the system subgroup information that corresponds to the user equipment group. In such a manner, system information that is generated due to a requirement of a new technology can be effectively reduced, and user equipment can be prevented from receiving information unrelated to the user equipment and triggering unnecessary behavior.

Claims

1. A method, comprising:

acquiring configuration information related to a first piece of system subgroup information of system information of a cell, wherein each piece of system subgroup information of the system information of the cell respectively corresponds to an area of the cell, and the first piece of system subgroup information corresponds to a first area of the cell; and

receiving, according to the configuration information and via a beam of a base station, the first piece of system subgroup information, wherein the beam corresponds to the first area of the cell.

2. The method according to claim 1, wherein the acquiring comprises:

acquiring, in connected mode, the configuration information using dedicated information.

3. The method according to claim 1, wherein the acquiring comprises:

acquiring, in idle mode, the configuration information using a radio resource control release message of an attach procedure.

4. The method according to claim 1, wherein the first piece of system subgroup information comprises system information content that is applied to one or more user equipment in the first area.

5. The method according to claim 1, wherein the first piece of system subgroup information corresponds to a demodulation reference signal.

6. The method according to claim 1, wherein acquiring the configuration information comprises:

receiving public system information, wherein the public system information comprises the configuration information and assistant identified fingerprint information.

7. A terminal device, comprising:

a processor, coupled to a transmitter; and

a receiver;

wherein the processor is configured to;
