Problems solved by technology
[0004] In the control information, a certain sub-information may appear all the time, such as SRS request information. However, when the TTI is shortened, the control information may appear more frequently, so some sub-information in the control information may be redundant. These redundant The remaining sub-information will increase the overhead of control information occupying system resources, thereby reducing the efficiency of data transmission

Embodiment Construction
[0238] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0239] In practice, network devices and user terminals can transmit data, such as control information and service data, through the LTE system. Wherein, the data sent by the network device to the user terminal may be called downlink data, and the data sent by the user terminal to the network device may be called uplink data; the network device may be a base station; the user terminal may be a mobile terminal or a PC (personal computer, personal computer) terminal. Such as figure 1 Shown is a system frame diagram of the embodiment of the present invention.
[0240] figure 1 Network devices in the figure 2 The computing device in , the schematic diagram of the organizational structure of the computing device is shown in FIG. Transc...

Embodiments of the present invention provide a method, device, and system for sending control information, which relate to the field of communication technology. The method includes: a network device determines the first time-frequency domain resource used to send the first control information. At least one information field included in the control information; the network device determines the number of bits of the first control information according to the at least one information field; the network device determines the number of bits in the first control information according to the number of bits of the first control information Sending the first control information to the user terminal in the first time-frequency domain resource. Through the present invention, the efficiency of data transmission can be improved.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for sending control information. Background technique [0002] With the development of communication technologies, Long Term Evolution (LTE, Long Term Evolution) systems are more and more widely used. In the LTE system, data in various physical channels can be transmitted according to a TTI (Transmission Time Interval, transmission time interval) of 1 ms. In order to reduce data transmission delay and improve data transmission efficiency, a short TTI data transmission mechanism is also set in the LTE system. The length of the short TTI is less than 1 subframe or 1 ms, for example, it may be 0.5 ms or 0.25 ms. [0003] In the LTE system, when the network device sends information to the UE (User Equipment, user terminal) in A TTIs or instructs the UE to send information in A TTIs, it will send control information in A TTIs, A is A positi...
