In each figure of the embodiment of the present invention, D represents DL, and U represents UL, and Un represents unknown resources Unknown.
Base station can configure a subcarrier spacing as reference subcarrier interval (Ref-SCS), according to this with reference to son for UE
The time slot format (slot format) at carrier wave interval and the reference subcarrier interval, determines other subcarrier spacings of the UE
Target BWP time slot format.For example, as shown in Fig. 2, distributing (cell- with the semi-static time-domain resource of cell-level
Specific semi-static DL/UL assignment) for, i.e., by taking cell-level configures time slot format as an example, for son
Carrier wave interval is the BWP of 30kHz or 60kHz, if Ref-SCS is 15kHz, according to the time slot lattice of Ref-SCS and Ref-SCS
Formula can determine that subcarrier spacing is the time slot format of the BWP of 30kHz or 60kHz.Specifically, according to subcarrier spacing with
The ratio of Ref-SCS determines the time slot format of subcarrier spacing.It is 15kHz with Ref-SCS, subcarrier spacing is 30kHz, than
For value is 2, then corresponding 2 subcarrier spacings of the uplink time-domain resource of a Ref-SCS are the uplink time-domain resources of 30kHz,
Corresponding 2 subcarrier spacings of the downlink time-domain resource of one Ref-SCS are the downlink time-domain resources of 30kHz, Ref-SCS's
Corresponding 2 subcarrier spacings of unknown resources are the unknown resources of 30kHz, Fig. 2 are specifically shown in, when each small lattice indicate one in Fig. 2
Gap.The unknown resources further progress time slot format determined in the semi-static time-domain resource of cell-level can also being distributed is matched
It sets, referred to as UE grades of semi-static time-domain resource distributes (UE-specific semi-static DL/UL assignment), i.e.,
UE grades of ground configure the format of each time slot, set that time slot format is similar, and difference is cell-level configuration time slot with cell gradation in Fig. 2
Format is as unit of time slot, and UE grades of configuration time slot formats are to be specifically shown in Fig. 3 as unit of symbol.
But by taking UE-specific semi-static DL/UL assignment as an example, according to the configuration of Ref-SCS
When determining the configuration of target BWP, if Ref-SCS is greater than the subcarrier spacing of target BWP, it is possible that target BWP
The slot format determined in one time slot according to time domain boundary alignment is unsatisfactory for defined DL-Unknown-UL mode
(pattern), occur more than one uplink and downlink transfer point in a time slot, will lead to the uplink and downlink transition overhead of user equipment
Increase.For example, specific as shown in Figure 4: as Ref-SCS=30kHz, the subcarrier spacing that target BWP is configured is
15kHz, then a time slot on target BWP structure need according to two subcarrier spacings be 30kHz time slot structure it is true
Fixed, the structure of time slot determined on target BWP is as shown in Figure 4, does not meet the mode of DL-Unknown-UL, that is, does not meet
Can only at most there be the structure of a uplink and downlink transfer point in structure of time slot, not be able to satisfy DL-Unknown-UL pattern time slot
Format.
In the embodiment of the present application, base station or UE are corresponding according to reference subcarrier interval and the reference subcarrier interval
The time slot format of time slot, it is determined that the subcarrier spacing of target BWP is less than the slot length of the target BWP at reference subcarrier interval
And the time slot format of the time slot of target BWP, it solves and is carried in the prior art when the subcarrier spacing of target BWP is less than with reference to son
When wave spacing, the time slot format for meeting the time slot of target BWP of DL-Unknown-UL pattern time slot format can not be configured
The problem of, so as to save resource overhead, resource utilization is improved, and improve system transfer rate.
