Detailed Description
Based on the listen-before-send mechanism proposed in the prior art, in practical applications, the mechanism also brings a problem that some data cannot be guaranteed to be sent at a determined position. Such a problem makes it impossible to ensure the performance if the existing 5G technology is directly applied to an unlicensed frequency band. Especially, when the design based on the 5G NR is independently deployed in the unlicensed frequency band, since the feedback information cannot be sent in time at a fixed time, the performance of the system based on the NR is greatly reduced when the traffic of the unlicensed frequency band is busy.
In order to achieve the purpose of the present application, an embodiment of the present application provides a method and a device for transmitting uplink control information, where a feedback time is determined, and the feedback time is used to instruct a terminal device to send uplink control information to a network device according to the feedback time; and sending the feedback time to the terminal equipment. By establishing a feedback mechanism between the network device and the terminal device, namely, the network device determines the feedback time and sends the determined feedback time to the terminal device, the terminal device sends uplink control information to the network device according to the feedback time to further inform the network device whether downlink data is correctly received, the problem of system resource waste caused by the fact that the network device has to send downlink data to the terminal device again because the network device cannot determine whether downlink data is correctly received is effectively avoided, meanwhile, the terminal device can also flexibly realize the feedback of the uplink control information according to the feedback time sent by the network device, and the system robustness of NR when the NR is independently deployed in an unauthorized frequency band is effectively enhanced.
Various embodiments of the present application are described in further detail below with reference to the figures of the specification. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The execution subject in the embodiment of the present application may be a base station device, and may also be a network side device, which is not specifically limited herein. Collectively referred to as network devices in the embodiments of the present application.
Step 101: and determining feedback time, wherein the feedback time is used for indicating the terminal equipment to send uplink control information to the network equipment according to the feedback time.
In the embodiment of the application, before the network device sends the downlink control information or the downlink data to the terminal device, the network device determines the feedback time, and the feedback time can indicate the opportunity of sending the uplink control information to the network device by the terminal device, so that the problem of system resource waste caused by the fact that the network device has to send the downlink data to the terminal device again because whether the terminal device correctly receives the downlink data cannot be determined can be effectively solved. Especially, data is transmitted in an unlicensed frequency band, so that not only can the terminal device be ensured to send uplink control information such as ACK/NACK to the network device at a determined position, but also the possibility of multiple choices in the listen-before-send technology can be ensured, and the situation that the uplink control information cannot be fed back to the network device in time after resources are occupied by other devices is avoided.
How the network device determines the feedback time is explained in detail below.
Specifically, the network device determines the current carrier busy level, and obtains the feedback time corresponding to the determined current carrier busy level according to a preset mapping relation between the busy level and the feedback time.
The feedback time described in the embodiments of the present application may refer to one time point, may refer to one time interval, may refer to a plurality of time points, and the form thereof is not particularly limited herein.
Preferably, the feedback time includes at least one time point.
Preferably, if the feedback time includes a plurality of time points, the time points satisfy that the time points are consecutive, or the time points satisfy that the time points are not consecutive.
Preferably, if the plurality of time points satisfy the time point discontinuity, the adjacent time points in the plurality of time points are equally spaced, or the adjacent time points in the plurality of time points are unequally spaced.
In this embodiment of the present application, the network device may determine a feedback time for the terminal device before sending downlink data or downlink control signaling to the terminal device each time; or when the current communication connection is established with the terminal device (the current communication connection can be understood as a process from the terminal device accessing the network device to the terminal device quitting the network device, for example, a user opens a mobile data switch of the terminal device to closes the mobile data switch of the terminal device), determining feedback time for the terminal device, and then in the current communication connection period, the terminal device defaults to send uplink control information to the network device according to the determined feedback time; the network device may also determine a feedback time (which may be referred to as a first feedback time) for the terminal device first, and then determine a feedback time (a second feedback time) for the terminal device when it determines that the carrier busy degree is sending a large change, that is, after the terminal device receives the first feedback time, if a different feedback time is not received or has not been received later, the uplink control information is sent according to the first feedback time.
The method for determining the carrier busy degree in the embodiment of the application includes but is not limited to:

wherein, U is a positive integer and represents the relevant time of the current service and the previous service; i is a positive integer and represents the ith downlink data transmission; a. theiIndicating the busy degree of a carrier corresponding to the ith downlink data transmission; a. the0The value is 1; and B is 0 or 1.
Further, in this embodiment of the present application, for the downlink data sent at the i-1 st time, if the terminal device sends the uplink control information at the first selectable feedback time point, the value B is 1, otherwise, the value B is 0.
How the network device determines the mapping relationship between the busy level and the feedback time is described in detail below.
The method comprises the following steps that firstly, time slots corresponding to carriers used for transmitting uplink data are divided into different time periods, and the time periods comprise at least one time point.
And secondly, determining the mapping relation between different time periods and busy degrees.
The higher the busy degree is, the more time points contained in the corresponding time period are and the different time points are not continuous; conversely, the lower the busy level, the fewer time points are included in the corresponding time period.
For example: first, handle [0, 1 ]]Is divided into M consecutive non-overlapping sub-intervals: { [0, a)1)，[a1,a2),..,[aM-1,1]Therein 0<a1<a2…<aM-1<1, the sizes of the sub-intervals can be the same or different.
Where M is a positive integer.
Next, the obtained subintervals are sorted. Wherein, the less the feedback time points are, the more the sequencing is; for the same number of feedback time points, the smaller the interval of the feedback time points, the earlier the ranking.
Thirdly, the busyness degree is sorted from small to large. I.e., the smaller the busyness value, the more forward the ranking.
Fourthly, according to the sorting structure, determining the mapping relation between different subintervals and the busy degree.
Step 102: and sending the feedback time to the terminal equipment.

and sending the feedback time to the terminal equipment through high-level signaling.
It should be noted that, in order to ensure that the network device can send the determined feedback time to the terminal device, in this embodiment of the present application, it is further required to add a length of "length to" in the existing signaling
Indication signaling of bits, wherein
Is rounded up.
According to the technical scheme provided by the embodiment of the application, the feedback time is determined, and the feedback time is used for indicating the terminal equipment to send the uplink control information to the network equipment according to the feedback time; and sending the feedback time to the terminal equipment. By establishing a feedback mechanism between the network device and the terminal device, namely, the network device determines the feedback time and sends the determined feedback time to the terminal device, the terminal device sends uplink control information to the network device according to the feedback time to further inform the network device whether downlink data is correctly received, the problem of system resource waste caused by the fact that the network device has to send downlink data to the terminal device again because the network device cannot determine whether downlink data is correctly received is effectively avoided, meanwhile, the terminal device can also flexibly realize the feedback of the uplink control information according to the feedback time sent by the network device, and the system robustness of NR when the NR is independently deployed in an unauthorized frequency band is effectively enhanced.

When the terminal device receives the feedback time sent by the network device, if the feedback time is determined not to be suitable for the busy degree of the current carrier, a new feedback time can be determined according to the mapping relation, and the determined new feedback time is notified to the network device through a high-level signaling or other manners.
