• a multi-PDSCH grant may include a set of SLIVs that do not conflict with any semi-static uplink symbols. However, in some cases, a SLIV of a PDSCH may conflict with a semi-static uplink symbol. Some aspects described herein provide handling for cases where a SLIV of a PDSCH in a multi-PDSCH grant conflicts with a semi-static uplink symbol. For example, in some aspects, a UE may treat a conflict between a SLIV of a PDSCH and a semi-static uplink symbol as an error case.
• Fig. 3 is a diagram illustrating an example 300 associated with multi-PDSCH grant configuration, in accordance with various aspects of the present disclosure. As shown in Fig. 3, a base station 110 and a UE 120 may communicate with one another.
• UE 120 may receive a PDSCH grant scheduling a set of PDSCH transmissions.
• UE 120 may receive a multi-PDSCH grant that includes a set of SLIVs for a set of PDSCH transmissions.
• at least one of the SLIVs identifies an OFDM symbol that overlaps with a semi-static uplink symbol.
• UE 120 may determine that a conflict exists between the SLIV (and a PDSCH associated therewith) and the semi-static uplink symbol.
• UE 120 may receive the multi- PDSCH grant in a DCI message.
• UE 120 may resolve the identified conflict between the SLIV and the semi-static uplink symbol. For example, UE 120 may treat an overlap between an OFDM symbol identified by a SLIV and a semi-static uplink symbol as an error case. In this case, UE 120 may return an error, cancel monitoring, and/or the like.
• UE 120 may cancel or delay reception of a PDSCH that includes the OFDM symbol. For example, UE 120 may cancel or delay reception of a PDSCH that includes the OFDM symbol. Additional details regarding canceling or delaying reception of a PDSCH are described with regard to Fig. 4.
• UE 120 may adjust a SLIV of a PDSCH that includes an OFDM symbol which overlaps with a semi-static uplink symbol. For example, UE 120 may adjust the SLIV, such that some OFDM symbols of the SLIV are used for the PDSCH and one or more OFDM symbols that overlap with or are within a threshold proximity of the semi-static uplink symbol are not used for the PDSCH.
• symbols 3- 7 may not be used for a PDSCH to enable UE 120 to switch between downlink reception or uplink transmission .
• symbols 3- 7 may not be used.

• UE 120 may monitor for and receive one or more PDSCHs based at least in part on the multi-PDSCH grant and based at least in part on resolving the identified conflict. For example, UE 120 may monitor for and receive a PDSCH that does not include an OFDM symbol that conflicts with a semi-static uplink symbol. Additionally, or alternatively, UE 120 may monitor for and receive a PDSCH that does include an OFDM symbol that overlaps with a semi-static uplink symbol based at least in part on delaying the PDSCH or adjusting the SLIV, among other examples.

• HARQ process IDs 0 through 7 are scheduled for slots 0 through 7 based at least in part on a multi-PDSCH grant.
• a PDSCH corresponding to HARQ process ID 1 conflicts with one or more uplink semi-static symbols in slot 1 (an OFDM symbol of the PDSCH overlaps with an uplink semi-static symbol in slot 1).
• UE 120 may cancel the PDSCH corresponding to HARQ process ID 1 and may transmit the PDSCHs corresponding to HARQ process IDs 0, 2, 3, 4, 5, 6, and 7.
• UE 120 cancels the PDSCH with the overlapping OFDM symbol without adjusting other PDSCHs of the multi-PDSCH grant. In this way, UE 120 avoids changing any PDSCHs for which there is not an overlapping OFDM symbol.
• UE 120 may cancel a PDSCH corresponding to HARQ process ID 7 and may transmit the PDSCHs corresponding to HARQ process IDs 0 through 6.
• UE 120 pushes back the PDSCHs to avoid overlapping with the semi-static uplink symbol and cancels one or more last PDSCHs. In this way, UE 120 avoids extending the multi-PDSCH grant beyond slot 7 for which the multi- PDSCH grant is scheduled.
• UE 120 may delay PDSCHs rather than canceling a PDSCH as a response to identifying a PDSCH with an overlapping symbol. In other words, UE 120 pushes back the PDSCHs and extends the multi-PDSCH grant to slot 8 to ensure reception of all PDSCHs of the multi-PDSCH grant. In this way, UE 120 avoids dropping a PDSCH corresponding to a HARQ process identifier as a response to identifying a conflict with an uplink semi-static symbol.
• some aspects are described in terms of a single conflicting PDSCH and a single response, multiple conflicting PDSCHs or multiple responses may be possible.
• UE 120 may cancel multiple PDSCHs with conflicting OFDM symbols or cancel a first PDSCH with a conflicting OFDM symbol and delay a second PDSCH with a conflicting OFDM symbol, among other examples.
• UE 120 may delay multiple sets of PDSCHs. For example, when UE 120 detects a first overlap at slot 1, UE 120 may delay PDSCHs 1 through 7 to slots 2 through 8 and UE 120 may detect a second overlap at slot 5 and, accordingly, delay PDSCHs in slots 5 through 8 to slots 6 through 9.
• Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.
• Fig. 5 is a diagram illustrating an example 500 associated with multi-PDSCH grant configuration, in accordance with various aspects of the present disclosure.
• Example 500 includes communication between a BS 110 and a UE 120 in connection with an overlap between an OFDM symbol in a PDSCH and a semi-static uplink symbol, as described above with regard to Fig. 3.
• HARQ process IDs 0 through 7 are scheduled for slots 0 through 7 based at least in part on a multi-PDSCH grant.
• a PDSCH corresponding to HARQ process ID 1 conflicts with one or more uplink semi-static symbols in slot 1 (an OFDM symbol of the PDSCH overlaps with an uplink semi-static symbol in slot 1).
• UE 120 may segment a set of symbols in a SLIV for the PDSCH corresponding to HARQ process ID 1 and skip one or more segments. For example, UE 120 may determine to skip a first segment that includes an OFDM symbol that overlaps with the semi-static uplink symbol.
• UE 120 may keep one or more second segments that do not include an OFDM symbol that overlaps with the semi-static uplink symbol. For example, as shown, UE 120 may keep a second segment before the semi-static uplink symbol and a second segment after the semi-static uplink symbol. In this case, UE 120 may monitor for the PDSCH in the second segments.
• UE 120 may perform a particular behavior with regard to the second segments. For example, UE 120 may keep a second segment when the second segment has a length greater than a threshold. For example, UE 120 may determine to keep the second segment when the second segment is two or more OFDM symbols long. In some aspects, UE 120 may rate match a transport block in the second segments. For example, UE 120 may keep all second segments and determine a transport block size based on a longest second segment of one or more second segments and rate match according to the determined transport block size. In another example, UE 120 may rate match according to a transport block size of a shortest second segment or an average of second segment lengths. In some aspects, UE 120 may discard one or more second segments. For example, UE 120 may keep only a longest second segment and may determine a transport block size for rate matching based on the length of the longest second segment.
