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

[0135] Step 101: Receive a downlink control channel and indication information used to indicate the division of uplink and downlink resources in a time unit.

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

[0137] Optionally, the step of receiving indication information for indicating the...

[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 used to indicate the division of uplink and downlink resources in a time unit.

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

[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. It is assumed 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 divisions in the current time unit; it is assumed that the UL grant sent in the downlink resource in the current time unit can schedule physical operations in the uplink area of ​​the current time unit Uplink shared channel PUSCH transmission ...

Abstract

The invention provides a data transmission method, a terminal and a base station, which solve the problem that in the prior art, how to transmit in a variable time slot structure is not given. The method comprises the following steps: receiving a downlink control channel and indicating information for indicating uplink and downlink resource division in a time unit; according to the indicating information, determining an uplink resource and / or a downlink resource in a target time unit corresponding to the downlink control unit, wherein the target time unit is a time unit where target transmission corresponding to the downlink control channel is located; determining a time domain resource of the target transmission corresponding to the downlink control channel in the uplink resource or thedownlink resource and carrying out the target transmission in the time domain resource so as to achieve the purpose of carrying out transmission in the variable time slot structure, so that the problem that in the prior art, how to transmit in the variable time slot structure is not given is solved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, terminal and base station. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as ITU (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 types of services, such as enhanced mobile broadband eMBB services, ultra-high reliability and ultra-low latency communication URLLC services, large-scale Internet of Things mMTC, etc. The business volume of the same service will also change. In order to support different service types and flexible traffic volume, transmission structures such as full downlink time slots, full uplink time slots, partial downlink and partial uplink time slots can be used, and partial downlink and partia...
