Problems solved by technology

However, the LTE system adopts the design concept in the licensed frequency band and lacks a similar back-off mechanism, thus causing difficulties for the use of the LTE technology on the unlicensed spectrum;
[0005] Second, the LTE system interferes with technologies such as wifi;

Embodiment 1

[0106] figure 1 It is a schematic diagram of the implementation process of the uplink transmission method in the embodiment of the present invention Figure 1 ;Such as figure 1 As shown, the method is applied to the base station side; the method includes:

[0107] Step 101: receiving an uplink scheduling request message;

[0108] Step 102: Determine the uplink scheduling grant signaling according to the uplink scheduling request message, and send the uplink scheduling grant signaling; wherein, the uplink scheduling grant signaling indicates N different subframes at different times; the N is A positive integer greater than or equal to 2.

[0109] Here, the N different subframes at different times indicated in the uplink scheduling grant signaling correspond to channels corresponding to unlicensed spectrum in the LTE system.

[0110]Here, the uplink scheduling grant signaling itself may identify whether its corresponding frequency band is a frequency band on the licensed spe...

[0129] image 3 It is a schematic diagram of the implementation process of the uplink transmission method in the embodiment of the present invention Figure II ;Such as image 3 As shown, the method is applied to the terminal side; the method includes:

[0130] Step 301: sending an uplink scheduling request message;

[0131] Step 302: Receive the uplink scheduling grant signaling determined according to the uplink scheduling request message; wherein, the uplink scheduling grant signaling indicates N different subframes at different times; the N is a positive integer greater than or equal to 2.

[0132] In the above solution, the N different subframes at different times indicated in the uplink scheduling grant signaling correspond to channels corresponding to unlicensed spectrum in the long term evolution system.

[0133] Here, the terminal sends an uplink scheduling request message to the base station, and the base station receives the uplink scheduling request message, det...

Embodiment 3

[0203] After receiving the uplink scheduling authorization signaling sent by the base station, the terminal performs uplink channel detection according to the uplink scheduling opportunity indicated by the uplink scheduling authorization signaling to lay the foundation for sending uplink service data; wherein, the uplink scheduling opportunity includes N , that is, N different subframes at different times; said N is a positive integer greater than or equal to 2; after N times of detection, the terminal finds that the interference in the channel to be transmitted is relatively large or the background noise is high, that is, it is considered that N times of uplink scheduling If the channels of the opportunity are all busy and cannot perform data transmission, the terminal will give up this uplink scheduling request after the N detection.

[0204] Figure 5 It is a schematic flow diagram of the specific implementation of the uplink transmission method in the embodiment of the pre...

Abstract

The invention discloses an uplink transmission method which is applied to a base station side. The method comprises the steps of receiving an uplink scheduling request message, determining an uplink scheduling grant signaling according to the uplink scheduling request message and sending the uplink scheduling grant signaling, wherein the uplink scheduling grant signaling indicates N different sub frames at different time moments, and N is a positive integer greater than or equal to 2. The invention further discloses a base station and a terminal.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to an uplink transmission method, a base station and a terminal. Background technique [0002] The Long Term Evolution (LTE, LongTermEvolution) system adopts a deterministic scheduling method based on base station authorization; specifically, in the LTE system, the terminal performs an uplink scheduling request to the base station, and after receiving the scheduling authorization from the base station, a period of time Then send the uplink service data; here, in the LTE system, the uplink scheduling request has a relatively definite timing relationship with the actual uplink service data transmission process; moreover, the LTE system adopts the continuous transmission mode, and only for the licensed frequency band Therefore, there will be no services of other systems in the LTE system, and the problem of signal interference is controllable. [0003] The widespread deploy...
