specific Embodiment approach 1

[0161] Specific implementation manner One, the network device determines the value of A according to the time of access to the channel.

[0162] Specifically, such as Picture 9 As shown, assuming that N is 14, the network device accesses the channel at time t0, and A can take any integer between 5 and 14. Unnecessary idleness in subframe n will cause a waste of resources on the one hand, and will make other systems access the frequency band on the other hand, so preferably, A=6.

specific Embodiment approach 2

[0163] Specific implementation manner 2: B selectable values ​​are agreed upon by the system or protocol, B is a positive integer less than or equal to N-1, and the network device selects one of the B selectable values ​​as the value of A according to the time of access to the channel value.

[0164] Such as Picture 9 As shown, assuming that N is 14, the system or protocol prescribes four A values, which are 2, 5, 8, and 11 respectively. The network device accesses the channel at time t0, then A can be 8 or 11. Preferably, A=8. The advantage of this method is that, due to the restriction on the value of A, the network equipment and terminal equipment will be simplified to a certain extent.

[0165] Step 704: The terminal device receives service data in the service subframe m.

[0166] Assume that the terminal device receives service data in the service subframe m and subsequent P-1 service subframes, where P is a positive integer.

[0167] Specifically, the terminal device schedul...

Abstract

The invention discloses a data transmission method, a feedback information transmission method and related equipment, which are used for providing a solution for transmitting data on an unlicensed frequency band in an LTE system. The data transmission method comprises the steps that: terminal equipment determines a starting time of a system wireless sub-frame on the basis of a signal / information sent by network equipment; the terminal equipment receives downlink control information according to a system wireless sub-frame n+1 starting time, wherein n is a serial number of the system wireless sub-frame; the terminal equipment determines a starting time of a service sub-frame m in the system wireless sub-frame n according to the downlink control information, wherein m is a serial number of the service sub-frame, the starting time of the service sub-frame m is different from the starting time of the system wireless sub-frame n, and the length of the service sub-frame equals the length of the system wireless sub-frame; and the terminal equipment receives service data during the service sub-frame m.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a data transmission method, feedback information transmission method and related equipment. Background technique [0002] With the continuous growth of mobile data service volume, frequency band resources are becoming more and more tight. Using only authorized frequency band resources for network deployment and service transmission may no longer meet the demand for mobile data service volume. You can consider deploying and transmitting mobile data on unlicensed frequency band resources. Services to improve frequency band resource utilization and improve user experience. The unlicensed frequency band is used as a secondary carrier, and the main carrier of the licensed frequency band is used to assist the transmission of mobile data services. [0003] Unlicensed frequency bands can be shared by multiple wireless communication systems such as Bluetooth, Wi-Fi, etc., and...
