Methods, systems, and devices for wireless communication are described. Some wireless communications systems (e.g., New Radio (NR) systems) may support the dynamic configuration of time intervals (or slots) for communication in a specific link direction (e.g., uplink, downlink, sidelink, etc.). In such cases, a base station may dynamically allocate time intervals (or slots) for broadcast or multicast data (e.g., via a physical downlink control channel (PDCCH)) based on the dynamically determined configuration of certain time intervals (or slots). The dynamic allocation of resources for broadcast or multicast data may ensure that broadcast or multicast data is not scheduled to be transmitted during time intervals configured for uplink communication. In some cases, the broadcast or multicast data may be transmitted on a portion of a system bandwidth that is frequency division multiplexed with another portion of the system bandwidth allocated for mobile broadband (MBB) communications.
