Abstract

The invention discloses an information transmission method, a terminal and a network device. The method includes: receiving configuration information of a downlink transmission identification signal; wherein, the configuration information includes: a detection cycle and / or a detection position; a detection cycle and a detection position indicated by the configuration information / or detection position, on the first time-domain transmission unit, detect the downlink transmission identification signal. The terminal in the embodiment of the present invention detects the downlink transmission identification signal on the first time-domain transmission unit according to the indication of the configuration information, and accordingly, the network device does not need to send the downlink transmission identification signal on each time-domain transmission unit with downlink transmission , which can reduce system overhead and improve system throughput.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, a terminal and a network device. Background technique [0002] In a mobile communication system, since an unlicensed frequency band (unlicensed spectrum) is shared by multiple technologies or multiple transmission nodes, this contention-based access method leads to uncertainty in channel availability time. Before sending information, the terminal or network device needs to do Clear Channel Assessment (CCA) / Extended Clear Channel Assessment (eCCA) to monitor the channel, that is, to perform Energy Detection (ED). When the energy is lower than a certain threshold, the channel is judged to be empty before transmission can begin. [0003] However, for a terminal that needs to receive data, regardless of whether the network device sends data, it must perform a physical downlink control channel (Physical Downlink ControlChannel, PDCCH...
