    Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support coexistence of broadcast communication protocols. In such cases, a first network node, such as a network entity, may broadcast a cell acquisition subframe (CAS) in accordance with a first broadcast communication protocol whose frequency resources overlap with frequency resources allocated in accordance with a second broadcast communication protocol. The CAS may indicate a modification to transmission of one or more subsequent CASs in accordance with the first broadcast communication protocol. For example, the modification may be a muting pattern, an updated periodicity, or both. As such, the first network node may broadcast, in accordance with the first broadcast communication protocol, the one or more subsequent CASs, wherein the one or more subsequent CASs are time division multiplexed with communications associated with the second broadcast communication protocol in accordance with the modification.

    Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.
