数据发送方法和用户设备技术

本申请实施例提供了一种数据发送方法和用户设备。本申请实施例的数据发送方法，包括：用户设备确定被基站调度的窄带时频资源；所述用户设备在所述窄带时频资源上进行空闲信道评估CCA信道检测，以得到所述窄带时频资源的信道能量值；所述用户设备判断所述信道能量值是否小于预设能量阈值；若所述信道能量值小于所述预设能量阈值，则所述用户设备在所述窄带时频资源上向所述基站发送上行数据。基站为用户设备调度窄带时频资源，从而用户设备在该窄带时频资源上发送上行数据。不同的用户设备可能在不同窄带时频资源上进行数据的传输，通过在窄带时频资源上进行CCA信道检测的方式可以增加用户设备接入信道的机会，增加了对上行时频资源的利用率。

Data transmission method and user equipment

The embodiment of this application provides a data transmission method and a user equipment. The data transmission method of the embodiment of the present application includes: the user equipment determines the narrowband time-frequency resource scheduled by the base station; the user equipment carries out idle channel evaluation CCA channel detection on the narrowband time-frequency resource to obtain the channel energy value of the narrowband time-frequency resource; and the user equipment determines the channel energy value. Whether it is less than the preset energy threshold or not; if the channel energy value is less than the preset energy threshold, the user equipment transmits upstream data to the base station on the narrowband time-frequency resource. The base station schedules the narrowband time-frequency resources for the user equipment, so that the user equipment transmits the upstream data on the narrowband time-frequency resources. Different user equipment may transmit data on different narrowband time-frequency resources. CCA channel detection on narrowband time-frequency resources can increase the access chances of user equipment to channel and increase the utilization rate of upstream time-frequency resources.
