Embodiment Construction

[0130] 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 with reference to 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.

[0131] figure 1 Is a flowchart of the signal processing method of the present invention, such as figure 1 Shown, including:

[0132] Step 100: Pre-set a subframe structure. The subframe structure includes at least: a first time slot and a second time slot. among them,

[0133] The first time slot is used for downlink signal transmission; or when no downlink signal is transmitted, that is, it is idle; or, it is switched to uplink signal reception and can be scheduled for uplink signal transmission, or uplink signal transmission is not scheduled and only switched to uplink signal reception. Us...

Abstract

The invention discloses a signal processing method, a base station and a terminal. The signal processing method comprises the following steps: presetting a sub-frame structure, wherein the sub-frame structure at least comprises a first time slot and a second time slot, the first time slot is used for sending a downlink signal, or is idle, or is switched to receive an uplink signal and schedule the transmission of the uplink signal, or not schedule the transmission of the uplink signal, or is switched to only receive and measure other signals without scheduling the signal reception of the uplink signal, and the second time slot is used for receiving the uplink signal and scheduling the transmission of the uplink signal, or is idle, or is switched to only measure the signal without scheduling the signal reception of the uplink signal; and receiving and sending signals by the base station based on the set sub-frame structure. By adopting the method disclosed by the invention, the use fairness of an unauthorized carrier frequency spectrum is improved, so that the unauthorized carrier frequency spectrum is effectively used.

Description

Technical field [0001] The present invention relates to LTE in unlicensed carrier technology, in particular to a signal processing method, base station and terminal based on LTE in unlicensed carrier system. Background technique [0002] LTE in the unlicensed carrier (LTE-U, LongTerm Evolution-Unlicensed) refers to the deployment of LTE in the unlicensed spectrum to meet the increasing capacity requirements of the LTE system and improve the efficiency of the use of unlicensed spectrum. It is LTE and future wireless A possible important evolution direction of communication. When designing LTE-U, it is necessary to consider how to fairly compete with other systems such as WiFi, radar, and the same system for unlicensed spectrum for data transmission. [0003] According to the presentation of the 3GPP standard meeting, for the scenario of authorized carrier assistance, the LTE-U system may also be referred to as the LTE Licensed Assisted Access (LAA, LTE Licensed Assisted Access) sys...
