Abstract

The invention discloses a method and a terminal for indicating channel transmission state. Wherein, the method includes: acquiring resources on the second frequency band; indicating the channel transmission status of resources scheduled to the first frequency band through the resources on the second frequency band, wherein the first frequency band is a frequency band that needs to perform LBT before listening , the second frequency band is a frequency band that does not perform LBT or a frequency band that occupies the current channel through LBT. The invention solves the technical problem that the uplink transmission method in the prior art cannot correctly give the channel transmission status, resulting in low uplink transmission efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and terminal for indicating channel transmission status. Background technique [0002] With the continuous development of existing technologies, mobile communication has been developed from the first generation to the fourth generation. Among them, the standard of the fourth generation mobile communication system is relatively unified in the world. The downlink is based on Orthogonal Frequency Division Multiple Access (OFDMA), and the uplink is based on Single Carrier–Frequency Division Multiple Access (SC-FDMA). The adaptive modulation and coding method achieves high-speed transmission with a peak downlink rate of 1Gbps and an uplink peak rate of 500Mbps. [0003] Since the licensed spectrum owned by the operator is limited, it is hoped to expand the capacity of LTE by using unlicensed spectrum resources. Based on the foregoing requirements, 3GPP formulated a stand...
