Embodiment 1

[0058] In this embodiment, a method operating on a 5G mobile communication network architecture is provided. The network architecture includes a base station and a terminal (or called a cellular user), wherein the signal sent by the base station to the terminal is called a downlink signal, and the terminal sends The signal sent by the base station is an uplink signal. In addition, the operation scenario of the data transmission method provided in the present application is not limited to the above network architecture, for example, it is also applicable to the D2D communication architecture (including the D2D sender and the D2D receiver). figure 2 is a flowchart of a data transmission method according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0059] Step S202, configure the downlink transmission unit in the following manner: configure the downlink transmission unit to send downlink control signals, down...

Embodiment 2

[0076] In this embodiment, a data transmission device is also provided, which is used to implement the above embodiments and preferred implementation modes, and what has already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0077] image 3 is a structural block diagram of a data transmission device according to an embodiment of the present invention, such as image 3 As shown, the device includes:

[0078] The configuration module 30 is configured to configure the downlink transmission unit in the following manner: configure the downlink transmission unit to sequentially send downlink control signals, downlink data and send a first designated signal within a ...

Embodiment 3

[0083] The embodiment of the present application also provides another data transmission method, which can be applied to the data receiving end, such as Figure 4 As shown, the method includes steps S402-S404:

[0084]Step S402, configure the uplink transmission unit in the following manner: configure the above-mentioned uplink transmission unit in sequence in time: send the second specified signal within the second time interval, transmit the uplink data, and transmit the third specified signal within the third time interval and sending an uplink feedback signal, wherein the above-mentioned uplink feedback signal is used for user feedback on downlink data;

[0085] Wherein, the above-mentioned uplink data is used to carry uplink data information. The above-mentioned uplink data information is sent by the cellular user to the base station, or sent by the D2D sender to the D2D receiver.

[0086] Optionally, the second specified signal includes one or more of the following sig...

The method comprises: performing data transmission on a down transmission unit configured according a following mode: the down transmission unit is configured to send down control signals and down data in time domain and send first assigned signals at first time intervals. According to the technical scheme, the problem is solved of resource efficiency and high delay demand in a 5G FDD system.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, traditional commercial communications mainly use 300MHz~3GHz Spectrum resources are extremely tense, which cannot meet the needs of future wireless communications. [0003] In the future wireless communication, it will be extended to support carrier frequencies higher than those used in the fourth generation (4G) communication system, such as 28GHz, 45GHz, etc., 5G new radio access technology (new Radio Access Technology , referred to as NR) system potential operating frequency band up to 100GHz. At the same time, compared with previous generations of mobile communicatio...
