Abstract

The embodiment of the invention discloses a transmitting method, system, base station and terminal for unauthorized frequency band uplinks. The method comprises the following steps: a base station determines behavior parameters of the uplink data transmission of the terminal and sends the behavior parameters of the uplink data transmission to the terminal; the terminal obtains the behavior parameters of the uplink data transmission transmitted by the base station; and based on the behavior parameters of the uplink data transmission, the resource occupation of public uplink resources or dedicated uplink resources is monitored.

Description

technical field [0001] The present invention relates to communication technology, in particular to an uplink transmission method, system, base station and terminal of an unlicensed frequency band. Background technique [0002] Deploying LTE on unlicensed carriers to meet the increasing capacity requirements of wireless communication systems and improve the efficiency of unlicensed spectrum usage is an important evolution direction of LTE and future wireless communications. The key condition for it to be realized is to ensure that the unlicensed frequency band can be shared fairly and reasonably like existing unlicensed frequency band wireless communication technologies such as wireless local area network (WLAN), that is, it can coexist well with other unlicensed technologies and be fair. share the use of unlicensed frequency bands. To meet this condition, it is necessary to ensure that the resource occupancy of the channel is monitored before the data is sent. This method i...
