Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for activating semi-static or periodic occasions for communications. A method that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a set of semi-static or periodic grant occasions for communications, receiving signaling configuring at least one set of semi-static or periodic resources for downlink (DL) transmission, decoding a DL transmission on the at least one set of semi-static or periodic resources, and communicating with a network entity in grant occasions in the set of semi-static or periodic grant occasions activated based on the decoded DL transmission.
