Abstract: Methods, systems, and devices for wireless communications are described to improve support for broadcast systems. In some wireless communications systems, such as broadcast systems for a multimedia broadcast/multicast service (MBMS), an inter-site distance between transmitters or between a transmitter and a receiver may be relatively large compared to an inter-site distance for other scenarios of a wireless communication system (for example, cellular data or talk scenarios). A transmitter in a broadcast system may adjust one or more characteristics of resources in a frame, such as the subframe structure, slot structure, or symbol structure, in carriers dedicated for MBMS resource transmissions. For instance, the transmitter may adjust durations of one or more symbols in a frame.
