Problems solved by technology

For mobile communication systems using MulteFire technology, since multiple unlicensed frequency band devices need to coexist and work under the LBT mechanism, the MCOT (Maximum Channel Occupancy Time, maximum channel occupancy time) of a single unlicensed frequency band device after each access channel is subject to the LBT Influenced by the mechanism, the channel is not always available for the unlicensed band device. For example, the longest channel occupation time of the current Multefire device cannot exceed 10ms. If the unlicensed band device does not complete the repetitive transmission within its own channel occupation time, It is likely to cause data transmission failure and affect the communication function

Embodiment 1

[0061] figure 1 A flow chart of a data time-domain transmission method according to an embodiment of the present invention is shown.

[0062] like figure 1 As shown, the data time domain transmission method of an embodiment of the present invention is used to transmit data in an unlicensed frequency band, including:

[0063] Step 102, within the current channel occupancy time, obtain the continuing transmission scheduling information issued by the base station.

[0064] The continuation scheduling information is the information indicating when and how the terminal performs repeated data continuation within the current channel occupation time, and the data continuation refers to the terminal uploading data to the base station and / or the base station sending data to the base station. The terminal sends data, and of course, data continuation can also be data interaction between two terminals.

[0065] Therefore, in the process of data transmission through the physical uplink s...

Embodiment 2

[0070] figure 2 A flow chart of a data time-domain transmission method according to another embodiment of the present invention is shown.

[0071] like figure 2 As shown, the data time domain transmission method of another embodiment of the present invention is used to transmit data in an unlicensed frequency band, including:

[0072] Step 202, detecting the start time point of the current channel occupation time at the base station side. That is, the time point at which the base station starts to occupy the current channel is acquired.

[0073] Step 204, detecting the interval between the time point at which data transmission stops in the previous channel occupation time and the start time point of the current channel occupation time.

[0074]Wherein, the time point at which data transmission stops can be any point within the previous channel occupation time, and can also be at the end time point of the previous channel occupation time. In this way, it can be accurately ...

Embodiment 3

[0103] exist figure 2 On the basis of the illustrated embodiment, the step of determining the first time point within the current channel occupancy time according to the continued transmission scheduling information may also be combined with Figure 5 and Image 6 Another implementation is shown.

[0104] like Figure 5 shown, including:

[0105] Step 502, determining a second time point at which the terminal detects the retransmission scheduling information, and a time interval between the second time point and the first time point.

[0106] Step 504: Add the second time point to the time interval to obtain the first time point. The time interval refers to the time interval required for data continuation after the second time point, that is,

[0107]

[0108] in, is the second time point when the terminal detects the continued transmission scheduling information, k is the time interval between the second time point and the first time point, k≥0, is the first time...

Abstract

The invention provides a data time domain transmission method, a control method, a terminal, a base station and a baseband chip. The data time domain transmission method is used for transmitting data in an unauthorized frequency band and comprises the following steps: obtaining continuous transmission scheduling information released by the base station within the current channel occupation time; and performing data continuous transmission within the current channel occupation time according to the continuous transmission scheduling information, wherein the data continuous transmission comprises that the terminal uploads data to the base station and / or the base station releases data to the terminal. By adoption of the technical scheme provided by the invention, the situation of data transmission failure caused by the uncompleted repeated data transmission within a single channel occupation time can be avoided, the repeated data transmission in the unauthorized frequency band by a communication device is realized, and the success rate of repeated transmission of the communication device is improved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of communication technology, in particular to a data time domain transmission method and control method, a terminal, a base station and a baseband chip. [0003] 【Background technique】 [0004] MulteFire technology is a wireless access technology that extends LTE (Long Term Evolution, Long Term Evolution) to unlicensed frequency bands. In this technology, carriers in unlicensed frequency bands can independently provide services without using licensed frequency band carriers. [0005] At present, in order to allow multiple unlicensed frequency band devices (such as Wi-Fi devices) to fairly occupy unlicensed frequency band channels and avoid mutual interference between unlicensed frequency band devices, a carrier similar to Wi-Fi is introduced in the MF (MulteFire) physical layer The LBT (Listen Before Talk) mechanism of listening technology, when the base station or terminal monitors that the unlicensed...
