Method and device for transmitting control information

A method for transmitting control information, for a control information receiving terminal, the control information comprising a first part of control information and a second part of control information;

• the method comprising:
• receiving, on a first time-frequency resource, the first part of control information from a control information transmitting terminal through a first physical layer channel;
• receiving first indication information from the control information transmitting terminal, the first indication information being configured to indicate a size of a second time-frequency resource and the second time-frequency resource being configured to be occupied when transmitting the second part of control information;
• and
• receiving, on the second time-frequency resource, the second part of control information from the control information transmitting terminal through a second physical layer channel;
• wherein the method further comprises:
• determining a value of a first parameter based on the first indication information;
• and
• calculating the size of the second time-frequency resource based on the first parameter,
• wherein the second physical layer channel is a physical layer channel for data transmission;
• and the first parameter includes a parameter for adjusting a ratio of coding efficiencies of the second part of control information and data information.

A device for transmitting control information, for a control information transmitting terminal, the control information comprising a first part of control information and a second part of control information;

• the device comprising:
• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• transmit the first part of control information to a control information receiving terminal through a first physical layer channel occupying a first time-frequency resource;
• transmit first indication information to the control information receiving terminal, the first indication information being configured to indicate a size of a second time-frequency resource and the second time-frequency resource being configured to be occupied when transmitting the second part of control information;
• and
• transmit the second part of control information to the control information receiving terminal through a second physical layer channel occupying the second time-frequency resource,
• wherein the processor is further configured to:
• calculate the size of the second time-frequency resource based on a first parameter;
• and
• determine the first indication information based on a value of the first parameter,
• wherein the second physical layer channel is a physical layer channel for data transmission;
• and the first parameter includes a parameter for adjusting a ratio of coding efficiencies of the second part of control information and data information.
