Embodiment Construction

[0186] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0187] figure 1 The flow chart of the method for realizing data processing of the present invention, as figure 1 As shown, the base station pre-schedules the target unlicensed carrier on the licensed carrier, specifically including:

[0188] Step 100: the base station determines to use an unlicensed carrier for data transmission, and notifies the UE of scheduling information.

[0189] In this step, the base station can decide to perform data transmission on the unlicensed carrier at any time;

[0190] It can also be determined to perform data transmission on an unlicensed ...

Abstract

The invention discloses a data processing method, a base station and a terminal. The data processing method comprises the steps that: the base station determines to use an unauthorized carrier to carry out data transmission and notifies scheduling information to UE; further, the UE judges that the base station pre-schedules the UE, the UE carries out modulation coding according to the scheduling, and meanwhile, the base station preempts an unauthorized carrier resource; and the UE sends data with modulation coding finished on the preempted unauthorized carrier resource. By adopting the data processing method provided by the technical scheme of the invention, when the base station determines to carry out the data transmission on the unauthorized carrier, and if the unauthorized carrier is not preempted temporarily, when preempting the unauthorized carrier, the UE carries out the modulation coding according to the scheduling, in this way, after the unauthorized carrier resource is preempted, a data transmission process on the unauthorized carrier resource can be carried out immediately or soon, so that the limited occupation time of an unauthorized frequency spectrum is fully used, and the utilization rate of the preempted unauthorized carrier resource is improved.

Description

technical field [0001] The invention relates to long-term evolution technology, in particular to a method for realizing data processing, a base station and a terminal. Background technique [0002] The Long Term Evolution (LTE / LTE-A, Long Term Evolution Advanced) system is a fourth generation mobile communication standard developed by a third generation partnership (3GPP, The 3rd Generation Partnership Project) organization. The LTE / LTE-A system uses key transmission technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) to improve spectral efficiency and peak transmission rate. LTE supports multiple bandwidth allocations, such as 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz, making spectrum allocation more flexible. The LTE / LTE-A system currently mainly works on the licensed spectrum, and the frequency bands selected in different regions are also different. For example, the North American network plans to use 700 / 80...
