Adjustment method and system for channel occupation probability and equipment

Abstract

The invention provides an adjustment method for channel occupation probability, an adjustment system for the channel occupation probability and equipment with a base station function. The adjustment method for the channel occupation probability comprises the following steps: adjusting parameter information, corresponding to a signal detection mechanism, of data to be sent according to the data type of the data to be sent of the equipment with the base station function; and adjusting the possibility of occupying a downstream channel of the data to be sent according to the adjusted parameter information, wherein the data type of the data to be sent comprises a found reference signal and / or downstream data. According to the adjustment method for the channel occupation probability, the capability of occupying the channel by an LBT (Listen Before Talk) mechanism for sending a DRS (Discovery Reference Signal) can be improved so that the found reference signal can more easily occupy the channel or at least has the channel occupation probability the same as that of an LBT mechanism for sending common downstream data, so that the power consumption caused by the fact that the reference signal DRS is measured by a terminal, and ell identification, downstream synchronization and time frequency estimation are carried out is reduced, and the accuracy is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a channel occupation probability adjustment method, a channel occupation probability adjustment system and a device with base station functions. 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 unlicensed frequency bands, because access technologies such as LTE have very high require...

Problems solved by technology

However, if the time when the LAA cell on the same frequency sends the reference signal DRS is too random, the terminal needs to consume more power in order to measure the adjacent cell, especially when measuring at different frequencies, it may not be possible because the adjacent cell does not seize the channel. Send DRS so that the terminal cannot even detect the reference signal DRS of a neighboring cell during the measurement gap

Moreover, if the LAA cell cannot send the reference signal DRS for a long time, the measurement accuracy of the terminal will be low
