5 . The method of claim 4 , wherein the first type of RRC signaling message is added to a user equipment information request signaling message.
6 . The method of claim 1 , further comprising:
sending full duplex information supported by the network device to a second terminal device via system information.
7 . The method of claim 6 , wherein the system information is minimum system information or other system information.
8 . The method of claim 1 , further comprising:
sending configuration information to a second terminal device in a connected state, wherein the configuration information is configured to notify the second terminal device to perform measuring and recording for a full duplex when the second terminal device is in an idle state.
9 . The method of claim 1 , wherein the recorded full duplex information at least comprises:
information about the network device supporting a full duplex communication; or
information about the network device supporting a full duplex communication and corresponding full duplex information; or
information about the network device with a specific full duplex condition.
10 . An information acquisition method, applied to a terminal device, comprising:
indicating to a first network device that the terminal device has recorded full duplex information, in a process of establishing a connection with the first network device;
wherein the recorded full duplex information is information about a second network device supporting a full duplex, which is measured and recorded based on a configuration requirement of the second network device when the terminal device is in an idle state.
11 . The method of claim 10 , wherein indicating to the first network device that the terminal device has the recorded full duplex information comprises:
indicating to the first network device that the terminal device has the recorded full duplex information via a first type of radio resource control (RRC) signaling message.
12 . The method of claim 11 , wherein the first type of RRC signaling message is added to any one of the following signaling messages:
a RRC connection setup complete signaling message;
a RRC connection reconfiguration complete signaling message;
a RRC connection reestablishment complete signaling message; or
a RRC connection resume complete signaling message.
13 . The method of claim 10 , further comprising:
receiving second indication information sent by the first network device; wherein the second indication information is configured to indicate the terminal device to report full duplex information required by the first network device; and
sending reported information to the first network device based on the second indication information.
14 . The method of claim 13 , wherein the first network device is used to configure a corresponding full duplex communication mode for the terminal device supporting a full duplex communication served by the first network device according to the reported information.
15 . The method of claim 13 , wherein the reported information is transmitted via a user equipment information response signaling message.
16 . The method of claim 10 , wherein measuring and recording the information about the second network device supporting the full duplex based on the configuration requirement of the second network device when the terminal device is in the idle state comprises:
receiving, by the terminal device, full duplex information supported by the second network device and sent by the second network device via system information.
17 . The method of claim 10 , wherein measuring and recording the information about the second network device supporting the full duplex based on the configuration requirement of the second network device when the terminal device is in the idle state comprises:
receiving, by the terminal device, configuration information configured by the second network device via a unicast radio resource control (RRC) signaling; and
measuring and recording the information about the second network device supporting the full duplex based on the configuration information, after the terminal device enters the idle state.
18 . A communication device, comprising:
a processor; and
a memory having stored therein computer programs,
wherein the processor is configured to:
receive first indication information sent by a first terminal device;
wherein the first indication information is configured to indicate to the communication device that the first terminal device has recorded full duplex information;
