- Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of FIG. 11 above.
- NR supports more flexible uplink and downlink configuration.
- the uplink and downlink configuration may be semi-statically configured and/or dynamically configured. Among them, the dynamic configuration is indicated by DCI format 2-0.
- the UE needs to determine whether it can send uplink transmission on a semi-statically configured or semi-persistently scheduled time-frequency resource based on the uplink and downlink configuration.
- the base station configures the UE to monitor PDCCH to receive DCI format 2_0, for a semi-statically configured or semi-persistent scheduled time-frequency resource that includes at least one symbol that is semi-statically configured as Flexible, if the UE does not receive DCI format 2_0, it indicates that If the symbol is uplink, the UE cannot send uplink transmission in this time-frequency resource. This is mainly to avoid interference with other devices.
- the UE does not receive the DCI format 2_0 indicating that the symbol is uplink can be divided into two types: does not receive the corresponding DCI format 2_0; receives the corresponding DCI format 2_0, but does not indicate that the symbol is uplink, for example, indicates that the symbol is D/F, or there is no indication of the configuration of the symbol.

- the base station may not be able to send a PDCCH carrying DCI format 2_0 due to channel access failure, and the UE may not receive DCI format 2_0.
- the UE will not be able to send the above uplink transmission. In other words, whether the UE can send uplink transmission that is not based on dynamic scheduling is still limited by the dynamic indication of the base station, which causes the efficiency of uplink transmission to decrease and the delay may increase.
- channel detection can avoid interference to other devices to a certain extent, in order to improve the efficiency of uplink transmission and reduce the delay. It can allow the UE to not receive the corresponding dynamic indication information (for example, DCI format 2_0, or another newly defined DCI format) used to indicate the uplink and downlink configuration, including the semi-static configuration as Flexible.
