Embodiment Construction

[0032] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0033] First, according to the application scenario of the present invention, there is an area covered by an LTE communication system, including at least one base station and at least one UE. In addition, there are multiple other unlicensed carriers in this area, wherein these unlicensed carriers may also be used...

Abstract

The invention discloses a wireless communication method and device, and in particular the wireless communication method and device which allocate transmitting power for non-authorized carrier waves at a base station of a LTE communication system. More than one non-authorized carrier wave is provided. The method and the device involve: the base station, prior to transmitting a demodulation reference signal each time, determining the carrier waves which require to be allocated with the transmitting power in the non-authorized carrier wave; and allocating the transmitting power to the carrier waves which require to be allocated with the transmitting power at each time of transmitting the demodulation reference signal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of wireless communication. Background technique [0002] In the field of wireless communication, generally speaking, the traditional deployment method is that the system works in a licensed frequency band (licensed band), that is, the entire spectrum resource is reserved for the system to use. Typically, the LTE communication system works using licensed frequency bands. [0003] However, with the further growth of wireless services, the requirements for the capacity and frequency band of the wireless communication system are also increased. In this case, the licensed frequency band resources of the LTE system appear to be relatively insufficient. Therefore, one of the recent research hotspots in the LTE field is how to use unlicensed frequency band resources to offload high-incidence data services. This kind of scheme is called LTE (LTE in Unl...
