Abstract: Interference for reference symbols in URLLC/eMBB multiplexing may be reduced. URLLC and/or eMBB reference signal (RS) interference may be reduced regardless whether the URLLC and eMBB reference signals and data are multiplexed and superimposed using the same numerology or different numerologies and/or regardless whether the URLLC and eMBB reference signals may be aligned or misaligned (e.g., may or may not use a common resource). An URLLC transmission may preempt an eMBB transmission. For the URLLC and eMBB transmissions using a same numerology, a RS reuse indication may be used. The RS reuse indication may indicate whether a RS in the preempted portion of the eMBB transmission may be reused. A channel estimation function set may be estimated, and channel estimation may be performed using the determined channel estimation function set. The eMBB transmission and the URLLC transmission may be decoded based on the performed channel estimation.

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.
