Abstract
In an interference control method, a first network device sends first indication information to a first terminal device, where the first indication information indicates a first reference signal (RS). The first terminal device obtains, based on measurement on the first RS, first interference information corresponding to the first RS, determines a first transmission parameter based on the first interference information, and sends uplink information to the first network device on a first time-frequency resource based on the first transmission parameter.
Claims16
A communication apparatus, comprising:
- at least one processor;
- and
- a non-transitory computer readable medium storing a program comprising instructions executable by the at least one processor for causing the communication apparatus to perform:
- receiving first indication information from a first network device, wherein
- the first indication information indicates a first reference signal (RS),
- the first RS corresponds to a second terminal device performing signal transmission with a second network device on a first time-frequency resource which is allocated by the first network device to the communication apparatus for uplink transmission, and
- that the second terminal device performs signal transmission with the second network device on the same first time-frequency resource allocated to the first terminal device is determined by the first network device based on resource allocation information of the second network device;
- obtaining, based on measurement on the first RS, first interference information corresponding to the first RS;
- determining a first transmission parameter based on the first interference information to avoid interference with the signal transmission between the second terminal device and the second network device on the first time-frequency resource;
- and
- sending uplink information to the first network device on the first time-frequency resource based on the first transmission parameter.
