Collision Handling of Synchronization Signal (SS) Blocks

Abstract:

A user equipment (UE) can include processing circuitry configured to decode synchronization information within a synchronization signal (SS) block, the SS block received within a SS burst set and occupying a subset of a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a physical downlink shared channel (PDSCH). A synchronization procedure can be performed with a next generation Node-B (gNB) based on the synchronization information within the SS block. The DM-RS can be detected within the slot, where the DM-RS starts at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data received via the PDSCH is decoded based on the detected DM-RS.
