Gap configuration for multiple transport blocks
Some techniques and apparatuses described herein provide for the determination of a gap for a scheduled communication involving multiple, different TBs. For example, some techniques and apparatuses described herein provide for the determination of a gap between two or more PDSCHs that are scheduled by a same DCI based at least in part on a UE capability, such as a processing time or a processing mode. Some techniques and apparatuses described herein provide for the determination of a gap between a last PDSCH and a next PDCCH based at least in part on the UE capability. The gap(s) may permit the UE to successfully receive and/or decode multiple PDSCHs and/or PDCCHs in view of the limitations imposed by the UE's processing time or processing mode. In this way, efficiency of PDSCH/PDCCH resource utilization may be improved, the likelihood of a failed PDCCH transmission is reduced, and network efficiency is improved.
