Communication method and apparatus, and device

A communication method, comprising:

• obtaining sidelink transmit power and uplink transmit power, wherein the sidelink transmit power is transmit power of a sidelink in a first time unit, and the uplink transmit power is transmit power of an uplink in the first time unit;
• and
• determining actual transmit power of the sidelink in the first time unit based on the sidelink transmit power, the uplink transmit power, and maximum transmit power, wherein
• the first time unit comprises N first time subunits, M second time subunits in the N first time subunits overlap uplink resources, N is an integer greater than 1, M is a positive integer less than or equal to N, the N first time subunits are time subunits used for sidelink transmission in the first time unit, and the actual transmit power of the sidelink is constant in the N first time subunits.

A non-transitory computer readable medium storing one or more instructions that, when executed by one or more processors of a first node, cause the first node to:

• obtain sidelink transmit power and uplink transmit power, wherein the sidelink transmit power is transmit power of a sidelink in a first time unit, and the uplink transmit power is transmit power of an uplink in the first time unit;
• and
• determine actual transmit power of the sidelink in the first time unit based on the sidelink transmit power, the uplink transmit power, and maximum transmit power, wherein
• the first time unit comprises N first time subunits, M second time subunits in the N first time subunits overlap uplink resources, N is an integer greater than 1, M is a positive integer less than or equal to N, the N first time subunits are time subunits used for sidelink transmission in the first time unit, and the actual transmit power of the sidelink is constant in the N first time subunits.
