Abstract

A method, adapted to a communication device, for uplink transmission by using unlicensed spectrum is provided. The method includes following steps. Acquiring transmission resource based on a listen-before-talk (LBT) procedure. Sending an LBT indicator to a base station after successfully acquiring the transmission resource. Receiving a uplink resource grant from the base station. Performing uplink data transmission with the base station on the unlicensed spectrum according to the uplink resource grant.

Description

technical field [0001] The present invention relates to a communication method and device, in particular to a communication method and device for uplink transmission using license-free frequency spectrum. Background technique [0002] With the development of communication technology, the mobile data usage of consumer electronic products has increased significantly. In order to meet the huge demand for bandwidth, the communication supervision agencies of various countries have successively released more spectrum and tried to improve the efficiency of spectrum use for mobile broadband services. For example, mechanisms such as Long Term Evolution in Unlicensed band (LTE-U) and Licensed Assisted Access (LAA) have been proposed to use unlicensed spectrum to amplify existing mobile communications. available spectrum. [0003] However, both LTE-U and LAA use unlicensed spectrum to make up for the shortage of downlink (downlink) licensed spectrum bandwidth. Currently, LTE-U or LA...
