Abstract
In the embodiments of the present invention, a first-type terminal increases signal transmit power and/or a second-type terminal decreases signal transmit power, or when selecting a resource location for signal transmission, a terminal may exclude a resource location that is close in frequency domain to and located in a same time interval as a resource location reserved by another terminal of a different type, or resource locations used by different types of terminals to transmit signals are separated by a resource location occupied by a guard band, to reduce in-band emission interference.
Claims21
A signal transmission control method, comprising:
- obtaining, by a terminal, power control information;
- and
- adjusting, by the terminal, signal transmit power based on a type of the terminal according to an instruction of the power control information;
- and
- transmitting a signal using adjusted signal transmit power,
- wherein the type of the terminal is a first type or a second type,
- wherein the power control information is configured as at least one of first instruction information or second instruction information when a first condition is met, wherein the first instruction information instructs a first-type terminal to increase signal transmit power, wherein the second instruction information instructs a second-type terminal to decrease signal transmit power, and wherein the first condition is that the first-type terminal and the second-type terminal share a resource pool,
- wherein the power control information is configured as at least one of the first instruction information or the second instruction information when both the first condition and a second condition are met, and wherein the second condition is that the first-type terminal and the second-type terminal transmit signals in a same time interval through frequency resource multiplexing, and
