Shared channel collision resolution and hybrid automated repeat request for semi persistent scheduling in sub-band full duplex

A method for wireless communications at a user equipment (UE), comprising:

• receiving first information that configures the UE for communications via sub-band full duplex (SBFD) symbols and via non-SBFD symbols in accordance with a first configuration for SBFD communications or a second configuration for SBFD communications, wherein the first configuration for SBFD communications defines valid symbols for the SBFD communications as corresponding to one of the SBFD symbols or the non-SBFD symbols, and wherein the second configuration for SBFD communications defines valid symbols for the SBFD communications as corresponding to both of the SBFD symbols and the non-SBFD symbols;
• receiving second information that configures a first plurality of semi-persistent scheduling physical downlink shared channel (SPS-PDSCH) messages;
• receiving third information that configures a second plurality of SPS-PDSCH messages for receipt, wherein a collision resolution procedure is triggered based at least in part on one or more of the second plurality of SPS-PDSCH messages at least partially overlapping with one or more of the first plurality of SPS-PDSCH messages;
• and
• selecting one or more instances of the first plurality of SPS-PDSCH messages for reception or feedback generation in accordance with the collision resolution procedure, wherein the collision resolution procedure includes application of one or more exclusion rules based at least in part on a first symbol type associated with the first plurality of SPS-PDSCH messages and a second symbol type associated with an individual SPS-PDSCH message of the first plurality of SPS-PDSCH messages, wherein the first symbol type and the second symbol type separately correspond to one of an SBFD symbol type or a non-SBFD symbol type.

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors to:

• receive first information that configures a UE for communications via sub-band full duplex (SBFD) symbols and via non-SBFD symbols in accordance with a first configuration for SBFD communications or a second configuration for SBFD communications, wherein the first configuration for SBFD communications defines valid symbols for the SBFD communications as corresponding to one of the SBFD symbols or the non-SBFD symbols, and wherein the second configuration for SBFD communications defines valid symbols for the SBFD communications as corresponding to both of the SBFD symbols and the non-SBFD symbols;
• receive second information that configures a first plurality of semi-persistent scheduling physical downlink shared channel (SPS-PDSCH) messages;
• receive third information that configures a second plurality of SPS-PDSCH messages for receipt, wherein a collision resolution procedure is triggered based at least in part on one or more of the second plurality of SPS-PDSCH messages at least partially overlapping with one or more of the first plurality of SPS-PDSCH messages;
• and
• select one or more instances of the first plurality of SPS-PDSCH messages for reception or feedback generation in accordance with the collision resolution procedure, wherein the collision resolution procedure includes application of one or more exclusion rules based at least in part on a first symbol type associated with the first plurality of SPS-PDSCH messages and a second symbol type associated with an individual SPS-PDSCH message of the first plurality of SPS-PDSCH messages, wherein the first symbol type and the second symbol type separately correspond to one of an SBFD symbol type or a non-SBFD symbol type.
