no. 1 example

[0134] Such as figure 1 As shown, the data transmission method of the embodiment of the present invention is applied to the terminal, including:

[0135] Step 101: Receive a downlink control channel and indication information for indicating division of uplink and downlink resources in a time unit.

[0136] In this step, the downlink control channel is a downlink control channel using an uplink DCI format (that is, a downlink control channel that carries an uplink scheduling grant, that is, an uplink scheduling instruction UL grant) and / or a downlink control channel that uses a downlink DCI format (that is, a downlink control channel that carries a downlink scheduling grant). The granted downlink control channel, that is, the downlink scheduling command DL grant, includes a downlink control channel indicating release of short downlink semi-persistent scheduling SPS resources).

[0137] Optionally, the step of receiving the indication information used to indicate the division o...

[0192] Such as figure 2 As shown, the embodiment of the present invention also provides a data transmission method applied to a base station, including:

[0193] Step 201: Send a downlink control channel and indication information for indicating division of uplink and downlink resources in a time unit.

[0194] In this step, the downlink control channel is a downlink control channel using an uplink DCI format (that is, a downlink control channel that carries an uplink scheduling grant, that is, an uplink scheduling instruction UL grant) and / or a downlink control channel that uses a downlink DCI format (that is, a downlink control channel that carries a downlink scheduling grant). The granted downlink control channel, that is, the downlink scheduling command DL grant, includes a downlink control channel indicating release of short downlink semi-persistent scheduling SPS resources).

no. 3 example

[0203] This embodiment is a specific application example of the data transmission method of the present invention.

[0204] The embodiment of the present invention takes a slot as a time unit as an example, assuming that a slot contains 7 symbols (orthogonal frequency division multiplexing OFDM or single carrier frequency division multiple access SC-FDMA symbols); of course, time units of other lengths are not excluded way of definition.

[0205] The specific implementation process of the data transmission method in the embodiment of the present invention is as follows.

[0206] It is assumed that the indication information sent at a specific time-frequency position in the current time unit is used to indicate the uplink and downlink area division in the current time unit; it is assumed that the UL grant sent in the downlink resources in the current time unit can be scheduled for physical Uplink shared channel PUSCH transmission (that is, the uplink processing delay of the te...

Abstract

The invention provides a data transmission method, a terminal and a base station, and solves the problem of how to perform transmission in a variable time slot structure which is not given in the prior art. The method of the present invention includes: receiving a downlink control channel and indication information used to indicate the division of uplink and downlink resources in a time unit; according to the indication information, determining the uplink resource and / or in the target time unit corresponding to the downlink control channel Downlink resource, wherein, the target time unit is the time unit of the target transmission corresponding to the downlink control channel; determine when the target transmission corresponding to the downlink control channel is in the uplink resource or the downlink resource domain resource, and perform the target transmission in the time domain resource, realize the purpose of transmission in the variable time slot structure, and then solve the problem that the prior art does not give how to perform in the variable time slot structure Transmission problem.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, a terminal and a base station. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as ITU (International Telecommunication Union, International Telecommunication Union) and 3GPP have begun to study new wireless communication systems (such as 5G systems). The new wireless communication system can support the coexistence of multiple service types, such as enhanced mobile broadband eMBB service, ultra-reliable and ultra-low-latency communication URLLC service, large-scale Internet of Things mMTC, etc., and the traffic volume of the same service will also change. In order to support different business types and flexible business volumes, transmission structures such as full downlink time slots, full uplink time slots, part downlink and part uplink time slots can be us...
