Abstract

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for selecting resources from a set of resources that are semi-persistently scheduled according to a first periodicity based on a supplemental configuration including a second periodicity. A base station and a user equipment (UE) may select resources for transmitting or receiving instances of one or more semi-persistently scheduled transmissions based on selecting resources from the set of resources based on the second periodicity and one or more selection criteria. In some examples, the base station and the UE may select an earliest resource or a next available resource of the set of resources with a period associated with the second periodicity. In some other examples, the base station and the UE may randomly select a resource of the set of resources within a period associated with the second periodicity.
