Description
Technical Field
The disclosure relates to the field of communication, and in particular, to a data transmission method and device, and a storage medium.
Background
In unlicensed spectrum, a transmitting end typically needs to monitor a channel, i.e., CCA (Clear Channel Assessment ), before occupying the channel to transmit data. If the transmitting end judges that the channel is idle after CCA detection, the transmitting end can occupy the channel to transmit data, otherwise, the transmitting end cannot occupy the channel. Its MCOT (Maximum Channel Occupy Time, maximum channel occupancy duration) may be agreed by the protocol or may be configured or indicated by the base station. The above procedure is generally referred to as a channel access (LBT) on unlicensed band (Listen Before Talk ) mechanism.
However, in the high frequency range, since the high frequency channel attenuates more, interference between transmission points may be small even if the transmission points are closer to each other. So in the NR (New Radio) 52.6 to 71GHz (gigahertz) issue, it has been determined that a channel access mechanism supporting no-LBT is required. That is, the transmitting end may directly transmit data without performing LBT before transmitting the data.

It has been determined in the related art that a channel access mechanism supporting no-LBT is required. That is, the transmitting end may directly transmit data without performing LBT before transmitting the data.
The data transmission method provided by the embodiment of the present disclosure is first described below from the base station side.
An embodiment of the present disclosure provides a data transmission method, which may be used in a base station, and referring to fig. 1, fig. 1 is a flowchart of a data transmission method, which is shown in an embodiment, and the method may include the following steps:
in step 101, idle period parameters are determined for a terminal employing a target channel access mechanism.
In the embodiment of the present disclosure, the target channel access mechanism includes that the transmitting end does not listen before transmitting data, i.e. the target channel access mechanism may be a no-LBT mechanism. The idle period is a period in which data transmission is stopped, and the idle period parameter is a related parameter required for the terminal to determine the idle period.
In step 102, the idle period parameter is transmitted.
In the embodiments of the present disclosure, the base station may transmit the idle period parameter to the terminal through, but not limited to, higher layer signaling or physical layer signaling. The higher layer signaling may include, but is not limited to, RRC (Radio Resource Control ) signaling, MAC (Media Access Control Address, media access control address) signaling.
In the above embodiment, the base station may determine the idle period parameter for the terminal adopting the target channel access mechanism, so that the terminal that does not listen before transmitting data stops transmitting data in the idle period, which avoids the terminal adopting the no-LBT mechanism on the unlicensed spectrum from occupying the channel for a long time, and improves the fairness of occupying the channel by the terminal.
In some alternative embodiments, referring to fig. 2, fig. 2 is a flow chart of a data transmission method according to an embodiment, the method may include the steps of:
in step 201, in response to the number of the terminals adopting the target channel access mechanism being plural, different idle period parameters are respectively determined for the plural terminals.
In the embodiment of the present disclosure, the number of terminals adopting the no-LBT mechanism may be plural, and accordingly, the base station may configure different idle period parameters for the plural terminals, so that the plural terminals stop data transmission in different idle periods, respectively.
In the above embodiment, the base station may configure different idle period parameters for a plurality of terminals adopting the target channel access mechanism, so that the plurality of terminals silence in different idle periods, that is, stop data transmission, thereby reducing channel interference and having high availability.
In some alternative embodiments, the idle period parameters include, but are not limited to, at least one of: the period duration of the idle period, the offset value of the start time of the idle period with respect to the start time of each period, the offset value of the start time of the idle period with respect to the reference point, the duration of the idle period in each period.

If the number of terminals adopting the target channel access mechanism is multiple, the base station may configure different idle period parameters for the multiple terminals, optionally, the different idle period parameters refer to each of the idle period parameters being different from each other, or at least one of the idle period parameters being different.
For example, the period duration configured by the base station for the terminal 1 and the terminal 2 using the target channel access mechanism is 10 ms, the duration of the idle period in each period is 1 ms, the offset value of the terminal 1 is 8 ms, the offset value of the terminal 2 is 9 ms, then the terminal 1 can stop data transmission at 8 th to 9 th ms, 18 th to 19 th ms, 28 th to 29 th ms … …, and the terminal 2 can stop data transmission at 9 th to 10 th ms, 19 th to 20 th ms, 29 th to 30 th ms … ….

The purpose of avoiding the terminal adopting the no-LBT mechanism from occupying the channel for a long time is achieved, and the fairness of the terminal occupying the channel is improved.
In some alternative embodiments, referring to fig. 9, fig. 9 is a flow chart of a data transmission method according to an embodiment, the method may include the steps of:
in step 901, a first transmission procedure of continuous data transmission is entered.

In step 1002, the target duration corresponding to the transmission duration of the first transmission procedure is determined based on a correspondence between the transmission duration and the interval duration.
The present disclosure does not limit the order of execution of steps 1001 and 1002 described above. In the embodiment of the present disclosure, the correspondence between the transmission duration and the interval duration may be a proportional relationship, and accordingly, the longer the transmission duration of the first transmission process, the longer the target duration, the shorter the transmission duration of the first transmission process, and the shorter the target duration may be.
In one example, a minimum interval duration may be set to avoid that the transmission duration of the first transmission procedure is too short, resulting in a target duration approaching 0, thereby causing the first transmission procedure and the second transmission procedure to proceed continuously.
In one example, a maximum interval duration may be set to avoid affecting terminal traffic if the first transmission procedure and the second transmission procedure are too long.
In another example, the minimum interval duration and the maximum interval duration may be set simultaneously, so as to avoid that the first transmission process and the second transmission process are continuously performed, and avoid that the interval between the first transmission process and the second transmission process is too long, so as to affect the terminal service.
In step 1003, a second transmission procedure of the continuous data transmission is entered in response to the first transmission procedure ending, at least for a target period of time.
In the above embodiment, the terminal may directly enter the first transmission process of continuous data transmission on the unlicensed spectrum, and after the first transmission process ends, at least the second transmission process of continuous data transmission is entered at intervals based on the target duration corresponding to the transmission duration of the first transmission process. The purpose of avoiding the terminal adopting the no-LBT mechanism from occupying the channel for a long time is achieved, and the fairness of the terminal occupying the channel is improved.
