Abstract
An in-device coexistence (IDC) indication message sending method includes a network device determining, when configuration information sent by the network device indicates that the terminal device can send an IDC indication message, a most proper IDC interference cancellation manner based on SUL frequency information, a type of an interfering frequency, a transmit power of the terminal device, a transmit power of the network device, a priority of a frequency band in which the interfering frequency is located, or an IDC interference cancellation manner expected by the terminal device that are indicated by the IDC indication message sent by the terminal device.
Claims20
An in-device coexistence (IDC) indication message sending method implemented by a terminal device, wherein the IDC indication message sending method comprises:
- receiving configuration information from a network device;
- and
- sending, when the configuration information indicates that the terminal device can send an IDC indication message, the IDC indication message to the network device,
- wherein the IDC indication message comprises interfering frequency indication information or priority indication information,
- wherein the interfering frequency indication information indicates supplementary uplink (SUL) frequency information or a type of an interfering frequency,
- wherein the interfering frequency indication information comprises a measurement object (MO) of the interfering frequency or the SUL frequency,
- wherein the priority indication information indicates a priority of a frequency band in which the interfering frequency is located, and
- wherein the priority indication information comprises second type indication information that indicates a type of the frequency band.
An in-device coexistence (IDC) indication message sending method implemented by a network device, wherein the IDC indication message sending method comprises:
