Embodiment 1

[0236] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, figure 1 It is a hardware structure block diagram of a mobile terminal of a data transmission method in an embodiment of the present invention. Such as figure 1 As shown, the mobile terminal 10 may include one or more (only one is shown in the figure) processor 102 (the processor 102 may include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), for A memory 104 for storing data, and a transmission device 106 for communication functions. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, the mobile terminal 10 may also include figure 1 more or fe...

Embodiment approach 1

[0362] In this preferred embodiment, in a high-frequency scenario, the transmission device uses the omnidirectional mode to send information, and / or, the LBT mechanism in the receiving mode.

[0363] In a low-frequency scenario, the transmission device uses an omnidirectional mode to send and / or receive information. Among them, for the application of low frequency to unlicensed spectrum, in order to meet the regulatory requirements on unlicensed spectrum, the transmission device needs to implement the LBT mechanism based on omnidirectional energy sensing before transmitting. Among them, for the LBT mechanism that performs energy sensing according to the omnidirectional mode, the signal energy perceived by the transmission device is equal to the accumulation and norm of the signals received by the transmission device from other surrounding transmission devices within the coverage area, that is, the transmission The signal energy perceived by the device is the accumulation of th...

Embodiment approach 2

[0373] In this preferred embodiment, in a high-frequency scenario, some transmission devices use the omnidirectional mode for transmission, and some transmission devices use the directional mode for transmission, and the LBT mechanism is given.

[0374] In a high-frequency scenario, the transmission device may use an omnidirectional mode and / or a directional mode to send and / or receive information. Similarly, if the high-frequency scenario is applied to an unlicensed spectrum, the transmitting device needs to implement the LBT mechanism before transmitting.

[0375] For high-frequency scenarios, some transmission devices use omnidirectional mode for transmission, while some transmission devices use directional mode for transmission. When the transmission device implements the LBT mechanism, it multiplexes the energy-based Perceptual LBT mechanism (also called omnidirectional energy-based LBT mechanism), the channel detection result may be inaccurate.

Abstract

The invention provides a data transmission method, a data receiving method, a data transmission device, a data receiving device, a base station and a terminal. The data transmission method comprises the following steps: obtaining predefined information; confirming whether executing the Listen Before Talk (LBT) mechanism before transmission or not according to the predefined information; and executing the LBT mechanism before a transmission device carries out transmission according to the predetermined transmission mode if the predefined information carries the LBT indicating information; or, executing non LBT predefined processing operation before a transmission device carries out the transmission according to the predetermined transmission mode if the predefined information does not carrythe LBT indicating information. Through the above steps, the signal in the beamforming system is processed separately by executing the LBT mechanism or executing the non LBT predefined process operation, therefore, the problem that the efficiency of the signal transmission is low in the beamforming system is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission and reception method, device, base station and terminal. Background technique [0002] The rapid development of mobile Internet and Internet of Things has triggered the explosive growth of data traffic and the widespread rise of diversified and differentiated services. As a new generation of mobile communication technology, the 5th Generation mobile communication technology (abbreviated as 5G) will support higher speed and huge High-volume links (one million connections per square kilometer), ultra-low latency (1ms), higher reliability, and 100-fold improvement in energy efficiency to support new demand changes. Among them, the goal of the 5G research phase (Study item, referred to as SI) is to determine and meet the design requirements of key technologies for new access (New Radio, referred to as NR) systems in any spectrum bandwidth range (at least 100GHz...
