Embodiment Construction

[0059] In the embodiment of the present invention, a plurality of transmission power constraint parameters are acquired, and a minimum value among the transmission power constraint parameters is determined; power control is performed according to the minimum value of the transmission power constraint parameters.

[0060] figure 1 It is a schematic flow chart of an unlicensed carrier power control method according to an embodiment of the present invention; figure 1 As shown, the unlicensed carrier power control method in the embodiment of the present invention includes:

[0061] Step 101: The UE acquires multiple transmit power constraint parameters, and determines the minimum value among the transmit power constraint parameters;

[0062] Here, in the case of open-loop power control, that is, when initial power setting is performed on the UE, the transmit power constraint parameters include:

[0063] Considering the maximum transmit power P of the unlicensed carrier spectrum ...

Abstract

The invention discloses a power control method for an unlicensed carrier. The method includes: acquiring a plurality of transmission power constraint parameters, and determining the minimum value of the transmission power constraint parameters; according to the minimum value of the transmission power constraint parameters, Perform power control. The invention also discloses an unlicensed carrier power control device.

Description

technical field [0001] The present invention relates to related technologies of unlicensed carrier power control in the field of mobile communication, in particular to an unlicensed carrier power control method and device. Background technique [0002] For communication systems using unlicensed carriers, it is necessary to avoid using unlicensed carriers being used by existing stations, otherwise it will cause mutual interference between systems; therefore, in some countries, such as Europe and Japan, support for unlicensed carriers is mandatory Listen before Talk (LBT, Listen before Talk) function, that is, before using an unlicensed carrier, it is necessary to perform a clear channel detection technology (CCA, clear channel assessment), if a device is found to be using the unlicensed carrier, or detect If the signal energy exceeds the CCA threshold, the access will be delayed; if the channel is found to be idle or the detected signal energy is lower than the CCA threshold,...
