Embodiment Construction

[0036] As the demand for wireless data increases, efficient use of resources becomes increasingly important. Accordingly, a wireless communication system (eg, New Radio (NR) system) can support flexible resource configuration (eg, for uplink or downlink communication) to efficiently allocate resources. For example, the base station may dynamically signal the configuration of time intervals (or time slots) for communication with user equipment (UE) based on eg traffic conditions in a particular link direction. Various users and applications can benefit from broadcast or multicast communications in a system that supports multiple concurrent services and frequent uplink traffic. Efficient techniques for scheduling the transmission of broadcast or multicast data based on dynamic time interval configurations may be desired to increase throughput in wireless communication systems.

[0037] As described herein, a base station may support dynamic signaling to indicate whether a time ...

Abstract

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 (orslots) 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 multicastdata 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.
