Embodiment Construction

[0186] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0187] figure 1 It is a flow chart of the method for data processing of the present invention, such as figure 1 As shown, the base station pre-schedules the target unlicensed carrier on the licensed carrier, which specifically includes:

[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 is also possible to determine whether to perform data transmission on an unlicensed carr...

Abstract

The invention discloses a method for realizing data processing, a base station and a terminal, including that the base station determines to use an unlicensed carrier for data transmission, and notifies the UE of scheduling information. Further, the UE determines that the base station pre-schedules it, and the UE performs modulation and coding according to the scheduling, and at the same time, the base station preempts unlicensed carrier resources; the UE sends modulated and coded data on the preempted unlicensed carrier resources. Through the technical solution of the present invention, when the base station determines to perform data transmission on an unlicensed carrier, if the unlicensed carrier has not been preempted temporarily, the UE performs modulation and coding according to scheduling while preempting the unlicensed carrier, so that After the unlicensed carrier resource is preempted, it can immediately or quickly enter the data transmission process on the unlicensed carrier resource. In this way, the limited occupation time of the unlicensed spectrum is fully utilized, and the utilization of the preempted unlicensed spectrum resource is improved. utilization rate.

Description

Technical field [0001] The present invention relates to long-term evolution technology, in particular to a method, base station and terminal for realizing data processing. Background technique [0002] The Long Term Evolution Advanced (LTE / LTE-A) system is a fourth-generation mobile communication standard formulated by the 3rd-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, etc., making spectrum allocation more flexible. The LTE / LTE-A system currently mainly works on licensed spectrum, and the frequency bands selected in different regions are also different. For example, the North American network plans to use 700 / 800MHz and 1700 / 1900MH...
