Abstract: The present disclosure relates to a channel estimation method of a wireless communication device. The channel estimation method includes descrambling a pilot signal having a unit symbol, dividing the descrambled pilot signal, and estimating a channel value of the wireless communication device. The descrambled pilot signal may be divided into a plurality of frequency resources with a first frequency resource and a second frequency resource and generating a first signal chunk with the first frequency resource and a second signal chunk with the second frequency resource. The channel value of the wireless communication device may be estimated based on the first signal chunk and the second signal chunk.

Abstract: Methods, apparatuses, and systems for wireless communications supporting dynamic spectrum sharing (DSS) between a first network (e.g., a New Radio (NR) network) and a second network (e.g., a Long Term Evolution (LTE) network) are described. In some aspects, asynchronous operation methods (e.g., methods for offsetting NR resources and LTE resources) are implemented to minimize overlap between resources allocated to synchronization signal blocks (SSBs) and resources allocated to cell reference signals (CRSs) based on time offsets between NR resources and LTE resources. For instance, SSBs in NR may be aligned with multicast-broadcast single frequency network (MBSFN) subframes, SSB allocated resources in NR may be offset to not overlap with CRS allocated resources in LTE, etc.
