Abstract

The invention provides a method and a system for indicating an idle state of a channel or reserving resources, a method and a system for indicating an idle state of an uplink channel or reserving the resources, an LTE (Long Term Evolution) terminal, an LTE base station and an LTE system. The method for indicating the idle state of the channel comprises the following steps of setting a channel monitoring sub-frame used for detecting the state of the channel in a frame structure in a time division or frequency division duplex mode; if the channel monitoring sub-frame internally detects that the channel is in the idle state, sending an indication, representing that the channel is in the idle state, to the terminal through a channel idle state signaling or a resource reservation signaling, and sending an indication, representing that the channel is occupied by the base station, to communication equipment requesting to occupy a non-authorized frequency band. According to the technical scheme, the understandings of the idle state of the channel and the reservation state of the resources by the terminal and the base station working in the non-authorized frequency band are consistent, and data based on the same core network can be seamlessly switched and transmitted in an authorized frequency band and the non-authorized frequency band.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular, to a method and system for indicating channel idle status or resource reservation, a method and system for indicating idle status of an uplink channel or resource reservation, an LTE terminal, a An LTE base station and an LTE system. Background technique [0002] With the rapid increase of communication traffic, the authorized spectrum of 3GPP is increasingly insufficient to provide higher network capacity. In order to further improve the utilization of spectrum resources, 3GPP is discussing how to use unlicensed spectrum, such as 2.4GHz and 5GHz frequency bands, with the help of licensed spectrum. These unlicensed spectrums are currently mainly used by Wi-Fi, Bluetooth, radar, medical and other systems. [0003] Usually, access technologies designed for licensed frequency bands, such as LTE (Long Term Evolution, long-term evolution) are not suitable for use in u...
