- Case 1 Conflict between SBFD time-frequency resources and PRACH uplink time-frequency resources, that is, the PDSCH carried by the SBFD time-frequency resources conflicts with the PRACH carried by the uplink time-frequency resources.
- the base station equipment Since the base station equipment knows the location of the PRACH uplink time-frequency resources, in order to ensure that the user equipment can use PRACH to send the access preamble normally and complete the initial access of the user equipment, the base station equipment needs to avoid dynamically configuring SBFD time-frequency resources in the uplink time-frequency resources occupied by PRACH. From the perspective of the user equipment, the user equipment does not expect to be dynamically configured with SBFD time-frequency resources on the uplink time-frequency resources that overlap with PRACH.
- the uplink data corresponding to the PRACH uplink time-frequency resources may include RACH opportunities (RO: RACH Occasion) and GP symbols that may exist before RO.
- the user equipment when the user equipment is not connected to the network, the user equipment needs to be ready to access the network at any time, so the PRACH uplink time-frequency resources cannot be occupied, and the downlink data corresponding to the PDSCH cannot be sent in the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources, such as SIB1.
- dynamic scheduling can be used to avoid sending the downlink data corresponding to the PDSCH on the conflicting SBFD time-frequency resources.
- the base station equipment does not send the downlink data corresponding to the PDSCH on the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources, and the user equipment will not receive downlink data in the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources.

- MSG 4 (4-step RACH) or MSG B (2-step RACH)
- PRACH and PDSCH are not used at the same time.
- PRACH uplink time-frequency resources are shared by multiple users
- the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources send downlink data corresponding to PDSCH to one user equipment, it will affect other user equipment to receive PRACH. Therefore, the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources do not send downlink data corresponding to PDSCH.
- PRACH uplink time-frequency resources are no longer needed after the user equipment accesses the network.
- other user equipment that has not accessed the network may initiate random access on the PRACH uplink time-frequency resources.
- the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources send downlink data corresponding to the PDSCH to one user equipment, it will affect other user equipment from receiving the PRACH. Therefore, the downlink data corresponding to the PDSCH is not sent on the SBFD time-frequency resources that conflict with the PRACH uplink time-frequency resources.
- the base station equipment will not send the downlink data corresponding to the PDSCH in any SBFD symbol that overlaps with the PRACH symbol, that is, it will not send the downlink data corresponding to the dynamically scheduled PDSCH, nor will it send the downlink data corresponding to the semi-statically scheduled PDSCH. Accordingly, the user equipment does not receive the downlink data corresponding to the PDSCH in the SBFD time-frequency resources.

If the first time slot and the second time slot are the same, the first time slot in the SBFD time-frequency resource overlaps with the second time slot in the PRACH uplink time-frequency resource. If the first time slot and the second time slot are different, the first time slot in the SBFD time-frequency resource does not overlap with the second time slot in the PRACH uplink time-frequency resource.
- the PRACH uplink time-frequency resources overlap with the SBFD time-frequency resources, such as the PRBs in the PRACH uplink time-frequency resources overlap with the PRBs in the SBFD time-frequency resources (partial overlap or complete overlap)

- SIB1 When the base station equipment sends SIB1 in the SBFD time-frequency resources that overlap with the PRACH uplink time-frequency resources, SIB1 will affect the detection performance of the PRACH preamble, and the user equipment will also be affected when sending the PRACH preamble.
- both PRACH preamble and SIB1 are important information, it is necessary to avoid scheduling SIB1 on PRACH uplink time-frequency resources to avoid interference with the two.

- the target PRB can be the PRB in the unoccupied symbols in the SRS uplink time-frequency resource, that is, the symbols occupied by the SRS uplink time-frequency resource are excluded from the SBFD time-frequency resource, the downlink data corresponding to the PDSCH is sent in the PRB of the remaining symbols, and the downlink data corresponding to the PDSCH is sent in the symbols not occupied by the SRS uplink time-frequency resource.
- the time-frequency resources corresponding to some PDSCH repeated transmissions do not overlap with the SRS uplink time-frequency resources, but the time-frequency resources corresponding to other PDSCH repeated transmissions overlap with the SRS uplink time-frequency resources.
- the following method can be used:
- Method A Based on the SBFD time-frequency resources that overlap with the SRS uplink time-frequency resources, the base station equipment ensures that all PDSCHs transmitted in the SBFD time-frequency resources (such as multiple PDSCH repeated transmissions) will not conflict with the SRS uplink time-frequency resources, that is, all PDSCH repeated transmissions use PRBs in unoccupied symbols of the SRS uplink time-frequency resources.

Then, the target PRB can be selected as an available time-frequency resource, and the downlink data corresponding to the PDSCH can be transmitted on the available time-frequency resource.
- DCI is required for scheduling. If the SBFD time-frequency resources that do not overlap with the SRS uplink time-frequency resources are sufficient for PDSCH retransmission, the base station device schedules PDSCH retransmission in the SBFD time-frequency resources, and the user equipment receives the downlink data corresponding to the PDSCH retransmission according to the scheduling information.

This parameter can be called the indication parameter of the PDSCH repetition transmission and SRS multiplexing mode. If RepetitionScheme Config-r16 is not configured, then RepetitionMultiplexingWithSRS is not configured either. If Repetition SchemeConfig-r16 is configured, then RepetitionMultiplexingWithSRS is used to indicate whether to adopt Scheme 1 or Scheme 2. For example, select one of the two options (noTx, rm), noTx means no transmission, which corresponds to Scheme 1, and rm means rate matching, which corresponds to Scheme 2.
