Abstract: A communication method in a frequency division duplex system is provided. The method includes a first terminal device that receives first dedicated signaling sent by a network device, and obtains a first configuration message. The first terminal device sends, based on the first configuration message, first information to the network device by using a second transmission frame structure, and receives second information that is sent by the network device by using the second transmission frame structure. The second transmission frame structure has a first fixed delay relative to a first transmission frame structure, and the first transmission frame structure is a frame structure that is used by a second terminal device to send third information to the network device and that is used by the network device to send fourth information to the second terminal device.

Abstract: A radio resource control (RRC) connection resume method includes receiving, by a first network device, an RRC connection resume request message from a terminal device. The RRC connection resume request message is used to request to resume an RRC connection of the terminal device. The method also includes sending a first message to a second network device. The first message includes auxiliary information. The auxiliary information includes at least one of information used by the terminal device to perform redirection or information used by the terminal device to perform cell reselection, or the auxiliary information indicates that the first network device cannot respond to the RRC connection resume request message of the terminal device. The method further includes receiving an RRC release message from the second network device. The method additionally includes sending the RRC release message to the terminal device.

Abstract: This present disclosure discloses example communication methods and communications apparatuses. One example communication method includes a terminal device determining a first offset of a first power class and a second offset of the first power class when a power class of the terminal device is the first power class. A compensation amount of the first power class is determined based on the first offset and the second offset. A determination as to whether to camp on a first cell is made based on the second offset and the compensation amount of the first power class.

Abstract: Example communication methods and apparatus in a wireless network are described. One example communication method includes establishing dual connections to a first access network device and a second access network device by a terminal device. A connection that is between the terminal device and the first access network device and that is included in the dual connections is a radio resource control (RRC) connection. The terminal device receives first configuration information sent by the first access network device. The first configuration information includes signaling radio bearer (SRB) configuration information of the second access network device and a trigger condition for using the SRB configuration information. When the trigger condition is met, the terminal device uses the SRB configuration information of the second access network device to establish an RRC connection to the second access network device.

Abstract: Embodiments of the present invention provide a communication method and apparatus. A network device determines, based on first capability information, a bandwidth part supported by a first terminal device, and sends a first paging message on a target bandwidth part, where the bandwidth part is used to carry paging or another message. The target bandwidth part matches the bandwidth part supported by the first terminal device. Therefore, compared with attempting to send the first paging message by the network device on a plurality of bandwidth parts, sending the first paging message on the target bandwidth part can effectively reduce a quantity of times of unnecessary paging sending by the network device, so as to reduce a quantity of wasted paging resources. This can effectively reduce a quantity of times of unnecessary listening of the first terminal device, reduce energy consumption of the terminal device, and improve paging efficiency.
