Power control method and apparatus

An apparatus, comprising:

• a communications interface;
• a processor;
• and
• a non-transitory computer readable medium storing a program for execution by the processor, the program including instructions to:
• determine a transmit power of uplink information and a transmit power of target information based on the target information and priorities of uplink transmission and sidelink transmission, wherein the uplink transmission comprises transmission of the uplink information by a first terminal device to a network device, wherein the sidelink transmission comprises transmission of sidelink information by the first terminal device to a second terminal device, wherein the target information is information that is in the sidelink information and that overlaps with the uplink information in a time domain in a scheduling time unit, wherein the target information comprises first information and second information, and wherein the target information is at least one of data information, scheduling assignment information, or sidelink feedback information, and wherein determining the transmit power of the uplink information and the transmit power of the target information comprises separately adjusting, in response to the priority of the uplink transmission being higher than the priority of the sidelink transmission, and based on the transmit power of the uplink information, at least one of a transmit power of the first information or a transmit power of the second information;
• and
• perform at least one of:
• send the uplink information based on the transmit power of the uplink information through the communications interface;
• or
• send the at least one of the first information or the second information based on the transmit power of the first information or the transmit power of the second information through the communications interface.

An apparatus, comprising:

• a non-transitory storage medium having instructions stored thereon;
• and
• one or more processors in communication with the storage medium, wherein the one or more processors execute the instructions to perform operations comprising:
• determining a transmit power of uplink information and a transmit power of target information based on the target information and priorities of uplink transmission and sidelink transmission, wherein the uplink transmission comprises transmission of the uplink information by a first terminal device to a network device, wherein the sidelink transmission comprises transmission of sidelink information by the first terminal device to a second terminal device, wherein the target information is information that is in the sidelink information and that overlaps with the uplink information in time domain in a scheduling time unit, wherein the target information comprises first information and second information, wherein the target information is at least one of data information, scheduling assignment information, or sidelink feedback information, and wherein the determining comprises separately adjusting, in response to the priority of the uplink transmission being higher than the priority of the sidelink transmission, and based on the transmit power of the uplink information, at least one of a transmit power of the first information or a transmit power of the second information;
• and
• performing at least one of:
• sending the uplink information based on the transmit power of the uplink information;
• or
• sending the at least one of the first information and the second information based on the transmit power of the first information or the transmit power of the second information.
