Abstract: A method and system are herein disclosed. The method includes receiving sounding reference signals (SRS) at a massive multiple-input multiple-output (MIMO) base station (BS) from a user equipment (UE), determining, at the BS, beamformers for known channels of the SRS, determining, at the BS, beamformers for unknown channels of the SRS based on the determined beamformers for the known channels, and selecting a modulation and coding scheme (MCS) based on the determined beamformers.

Abstract: An electronic device and a method for managing an electronic key thereof are provided. The electronic device includes a wireless communication circuit, a hardware-based security element comprising circuitry configured to provide a timestamp, a processor operatively coupled with the communication circuit and the security element, and a memory operatively coupled with the processor. The memory stores instructions that when executed by the processor, control the electronic device to: launch an application related with an electronic key of a door lock, receive an input for using the electronic key to open the door lock through the application, determine the validity of credential information related with the input, based at least in part on the timestamp, and open the door lock based on the validity of the credential information.

Abstract: A method and apparatus are provided. The method includes receiving a signal from a transceiver, demapping a bit pattern encoded within the signal, detecting a preamble based on the demapped bit pattern, and synchronizing the transceiver to a receiver using the preamble, wherein demapping the bit pattern is based on weighting coefficients.
