    Abstract: A wireless communication device includes a communication circuit configured to receive a channel state information reference signal (CSI-RS), a processor, which includes an angle of departure (AoD) monitoring circuit configured to extract AoD values corresponding to the received CSI-RS and an interference cancellation circuit configured to cancel second AoD values corresponding to an interfering cell adjacent to a serving cell other than first AoD values corresponding to the serving cell among the AoD values, and a memory storing the first AoD values corresponding to the serving cell and antenna array information of the serving cell.

    Abstract: Provided is an operating method of a wireless communication device, the method including receiving a channel state information reference signal (CSI-RS) from a base station, generating channel information by estimating a channel between the wireless communication device and the base station, based on the CSI-RS, and reporting the channel information to the base station, wherein the generating of the channel information includes generating first compressed data by compressing, in a spatial domain, channel characteristic information of a subband in which the CSI-RS is received, generating second compressed data by compressing the first compressed data in a frequency domain by using a first Discrete Fourier transform (DFT) function having a size corresponding to the number of subbands in which the CSI-RS is received in a bandwidth part (BWP) for communication with the base station, and generating the channel information, based on the second compressed data.

    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.
