Step 102, when there is a conflict between the downlink information transmission resources configured by the RRC and the uplink information transmission resources, one of receiving downlink information and sending uplink information is performed.

Through the embodiment of the present invention, when there is a conflict between the downlink information transmission resources configured by RRC and the uplink information transmission resources configured by RRC, one of receiving downlink information and sending uplink information can be performed, so as to achieve conflict between uplink and downlink information transmission resources When defining the purpose of the UE's code of conduct.

Because through the embodiment of the present invention, when there is a conflict between the downlink information transmission resources configured through RRC and the uplink information transmission resources configured through RRC, the UE can perform one of receiving downlink information and sending uplink information. In the case of giving up receiving downlink information and sending uplink information due to conflict, resource utilization can be improved.

In this embodiment of the present invention, when there is a conflict between the downlink information transmission resources configured through the RRC and the uplink information transmission resources, the UE may execute the one with higher priority of receiving downlink information and transmitting uplink information. For example, the UE may determine to receive downlink information. The priority of sending uplink information is higher than the priority of sending uplink information, the UE receives the downlink information and gives up sending uplink information, or the UE can determine that the priority of sending uplink information is higher than the priority of receiving downlink information, the UE sends uplink information and gives up Receive downstream information.

In the embodiment of the present invention, both the downlink information transmission resources and the uplink information transmission resources are obtained through RRC configuration, and both are resources whose transmission direction is not determined.

Specifically, in a TDD system, the network-side device can perform semi-static UL/DL configuration on the UE, wherein the UL/DL configuration indicates not only uplink resources and downlink resources, but also flexible resources, and the transmission direction of flexible resources is not determined. . The transmission direction of the Flexible resource can be rewritten through signaling such as RRC and dynamic slot format indicator (Dynamic Slot Format Indicator, dynamic SFI).

For flexible resources, the network-side device can configure the UE to send uplink information or receive downlink information on the flexible resources through RRC. For example, the network-side device generates configuration information, and the configuration information is used to configure the UE to configure the uplink information to send on the flexible resources through RRC. Or downlink information reception, such as sending SR, SRS, information carried by PRACH, etc., monitoring PDCCH, detecting SSB, detecting CSI-RS, etc. The network side device sends the configuration information to the UE, and the UE performs uplink information transmission or downlink information reception on flexible resources according to the configuration information.

If the PRACH is indicated by the PDCCH, the information carried by the PRACH is sent.

Specifically, if the PRACH is indicated by the PDCCH (PDCCH ordered), that is, the UE performs non-contention random access, the UE preferentially sends the information carried by the PRACH, and gives up monitoring the PDCCH. The UE may determine that the priority of sending uplink information is higher than the priority of receiving downlink information.

Conversely, if the PRACH is not ordered by the PDCCH, the UE may monitor the PDCCH preferentially and give up sending the information carried by the PRACH.

It should be noted that the PDCCH in "PRACH is not indicated by PDCCH" described here is not the same PDCCH as the PDCCH monitored by the UE in step 102. Similarly, the PDCCH in "PRACH is not indicated by PDCCH" described here is the same as the PDCCH described here. The PDCCHs monitored by the UE in step 102 are not the same PDCCHs.
