Abstract: This application provides a carrier configuration method and a communication apparatus. The method may include: a terminal device accesses a first cell by using a control channel resource of a first carrier. The terminal device receives first carrier configuration information in the first cell. The first carrier configuration information is used to change a carrier of the terminal device from the first carrier to a second carrier in the first cell. The first carrier and the second carrier share the control channel resource, and include different spectrum resources. According to this application, spectrum resource utilization of the first cell can be improved.

Abstract: This application provides example communication methods and apparatuses, and example computer-readable storage medium. One example method includes receiving a first timing advance (TA) value from a network device, where the first TA value is determined based on a timing advance offset and a distance between the network device and a terminal device. A first uplink signal is sent to the network device based on the first TA value, where boundaries of uplink frames corresponding to the first uplink signal and a second uplink signal in the network device are the same, and the first uplink signal and the second uplink signal are signals of different systems.

Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. In the method, a terminal may send, to a network device, a quantity of radio frequency channels supported on each of a plurality of carriers when the terminal performs uplink transmission on the plurality of carriers in TDM mode. In this method, the terminal may report, to the network device, a quantity of radio frequency channels used on each carrier when the terminal performs uplink transmission in TDM mode, so that the network device can configure, for the terminal based on an actual capability of the terminal, the quantity of radio frequency channels used on each carrier in TDM mode. This improves an uplink transmission capability of the terminal.

Abstract: An uplink determining method and an apparatus. An access network device may determine, based on signal quality of a downlink frequency band corresponding to a supplementary uplink (SUL) or signal quality of a frequency band of an SUL, the signal quality of the frequency band of the SUL, to accurately evaluate coverage performance of the SUL; and after determining the signal quality of the frequency band of the SUL, may determine whether to perform transmission on the supplementary uplink, to avoid a case in which the access network device blindly indicates a terminal to perform transmission on the supplementary uplink when signal quality of the supplementary uplink is not measured, leading to transmission of the terminal on the supplementary uplink with poor coverage and even a failure, thereby improving reliability and a transmission rate of uplink transmission and improving user experience.

Abstract: This application relates to communication methods and apparatuses. An access network device determines that a first beam of a first cell meets a load migration condition, and the access network device evaluates performance of the first terminal device on N candidate beams based on information about the N candidate beams. When determining, based on the result of the evaluation, that a first candidate beam satisfies a performance requirement in the N candidate beams, the access network device migrates the first terminal device to a second cell to which the first candidate beam belongs.

Abstract: An access network device sends resource information to a terminal device, where the resource information includes information about N uplink resources and information about M downlink resources, and N and M are integers greater than or equal to 2. The terminal device sends a random access request to the access network device using one of the N uplink resources (namely, a first resource). Correspondingly, the access network device may receive the random access request from the terminal device over the first resource, and may send a random access response to the terminal device using one of the M downlink resources (namely, a second resource).

Abstract: Embodiments of this application provide an uplink switching solution. In this solution, switching is performed between an SUL and an NUL, and a switching time period for the switching between the SUL and the NUL is longer than 0 microseconds. Therefore, the SUL and the NUL can share a radio frequency channel, so that the shared radio frequency channel can be switched between the SUL and the NUL, thereby improving utilization of the radio frequency channel, and improving uplink transmission performance.

Abstract: A first access network device receives an addition request message from a second access network device. The first access network device determines a third uplink carrier used by a terminal to send a preamble to the first access network device, and sends an addition request acknowledgement message to the second access network device. The addition request acknowledgement message includes carrier indication information. The carrier indication information indicates the third uplink carrier. The third uplink carrier is at least one of the first uplink carrier or a second uplink carrier. The second uplink carrier and the first uplink carrier belong to a same cell of the first access network device and the second uplink carrier is a supplementary uplink carrier.
