Step 201: Send a downlink control channel and an indication message for indicating the division of uplink and downlink resources in a time unit.

In this step, the downlink control channel is a downlink control channel using an uplink DCI format (ie, a downlink control channel carrying an uplink scheduling permission, ie, an uplink scheduling instruction UL grant) and/or a downlink control channel using a downlink DCI format (ie, carrying a downlink scheduling The permitted downlink control channel, that is, the downlink scheduling instruction DL grant, includes a downlink control channel instructing the short downlink semi-persistent scheduling SPS resource release).

Step 202: Determine the uplink resource and/or the downlink resource in the target time unit corresponding to the downlink control channel according to the instruction message, where the target time unit is the time unit where the target transmission corresponding to the downlink control channel is located.

This step is the same as the above step 102 and will not be repeated here.

Step 203: Determine the target transmission corresponding to the downlink control channel in the uplink resource or the time domain resource in the downlink resource, and perform the target transmission in the time domain resource.

This step is the same as the above step 103 and will not be repeated here. For the uplink shared channel, the base station is the receiving behavior, for the downlink shared channel, the base station is the transmitting behavior, and for the ACK/NACK feedback message, the base station is the receiving behavior.

In the data transmission method of some embodiments of the present invention, the base station sends a downlink control channel and an indication message indicating the division of uplink and downlink resources in the time unit; according to the indication message, the target time unit corresponding to the downlink control channel is determined. Uplink resources and/or downlink resources, where the target time unit is the time unit where the target transmission corresponding to the downlink control channel is located; when the target transmission corresponding to the downlink control channel is determined in the uplink resource or the downlink resource Domain resource, and the target transmission is performed in the time domain resource, which realizes the purpose of performing the target transmission on the determined time domain resource, and further solves the related technology does not give how to perform in the variable slot structure Problems with transmission.

Some embodiments of the present invention take 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, other lengths are not excluded How time units are defined.

The specific implementation process of the data transmission method of some embodiments of the present invention is as follows.

It is assumed that the indication message sent at a specific time-frequency location in the current time unit is used to indicate the division of the uplink and downlink regions in the current time unit; it is assumed that the UL grant sent in the downlink resource in the current time unit can schedule the uplink region in the current time unit for physical Uplink common channel PUSCH transmission (that is, the terminal's uplink processing delay is sufficient, of course, this scheduling relationship may not be pre-agreed, and may be notified in the UL grant, for example, directly notify the PUSCH in the current or the next or several time units Transmission).

As shown in FIG. 3, the base station first determines the size of the downlink area and the uplink area that divide the time unit i, and sends the indication message on a specific time-frequency resource in each time unit that sends the indication message to notify the time unit The division of uplink and downlink areas can be notified in the time unit of the downlink area size, uplink area size, and GP size of the two indications, or can be notified of one of a variety of predefined uplink and downlink structure types; then in a time unit In the downlink area of the system, a UL grant is sent, and the terminal is scheduled to perform PUSCH transmission in the uplink area of the time unit; finally, according to the size of the uplink area indicated by the above indication message, the terminal receives the frequency domain resource scheduled by the UL grant to send the terminal PUSCH.

The terminal first detects the indication message on a specific time-frequency resource in each time unit that sends the indication message, and determines the division of the uplink and downlink areas of the time unit. The specific notification method can be consistent with the agreement of the base station, which can be listed on the base station side. Any way. Among them, if the uplink and downlink resource division of a time unit is indicated by the indication message sent in the time unit before it, when the terminal judges that a time unit is full uplink according to the indication message, it can determine that the indication is not detected in the time unit Message, so as to achieve the purpose of power saving; then the terminal detects the UL grant in the downlink area of a time unit; finally, when receiving the UL grant, according to the frequency domain scheduling message in the UL grant, in the uplink area of the time unit PUSCH transmission The PUSCH occupies all time domain resources in the uplink area, that is, the PUSCH is transmitted according to the time domain length of the uplink area.

In some embodiments of the present invention, only the indication message sent in the current time unit indicates the division of the uplink and downlink regions in the current time unit as an example. Of course, if the indication relationship is the next time unit or the next few time units, the method is similar. They are all included in the present invention and will not be repeated here; the scheduling relationship may also be that the UL grant sent in time unit i schedules PUSCH transmission in time unit i+1, or the UL grant sent in time unit i schedules in time unit i and PUSCH is transmitted in i+1 (of course, more consecutive time units can also be scheduled); various ways of scheduling relationships and various indication relationships of indication messages can be combined with each other.

As shown in FIG. 4, the indication message sent in the current time unit indicates the division of the uplink and downlink regions in the next time unit, and the UL grant sent in the current time unit schedules PUSCH transmission in the uplink region in the next time unit, assuming the time unit The indication message in i+1 indicates that the time unit i+2 is full uplink, then the uplink area in the time unit i+1 is adjacent to the uplink area in the time unit i+2, and then the PUSCH can only be scheduled at one time The uplink area transmission in the unit, such as PUSCH1 scheduled by UL grant1 and PUSCH3 scheduled by UL grant3, can also be scheduled to transmit across the uplink area in two time units, such as PUSCH2 scheduled by UL grant2.

As shown in FIG. 5, the indication message sent in the current time unit indicates the division of the uplink and downlink regions in the next time unit, and the UL grant sent in the current time unit schedules PUSCH transmission in the uplink region in the current or next time unit, For example, UL grant1 in time unit i schedules the transmission of PUSCH1 in the uplink area of the next time unit i+1, and UL grant2 in time unit i+1 schedules the transmission of PUSCH2 in the uplink area of current time unit i+1. The UL grant3 in the inter-unit i+1 schedules the uplink area in the current time unit i+1 and the transmission of PUSCH2 in the next time unit i+2; of course, other combination relationships are also included in the present invention; the above embodiments only use PUSCH Take the transmission of all symbols in the uplink area in a time unit as an example. Of course, if there is an indication message in the UL grant indicating the length of the PUSCH transmission time domain (that is, the number and position of occupied symbols), the PUSCH may also occupy only the uplink area. Part of the symbol transmission.

The above embodiment only takes the UL grant scheduling relationship as an example, the DL grant scheduling relationship is similar, and the ACK/NACK feedback relationship is also similar, which will not be described in detail.
