A wireless communication device includes a plurality of antenna modules at different positions, a first radio frequency (RF) integrated circuit, and processing circuitry configured to select one antenna module from among the plurality of antenna modules to obtain a selected antenna module, perform communication using the selected antenna module and the first RF integrated circuit, monitor signal quality through at least one of the plurality of antenna modules to obtain a monitoring result, and control switching from the selected antenna module to another antenna module among the plurality of antenna modules based on the monitoring result, the switching including selectively switching a connection of the first RF integrated circuit from the selected antenna module to the other antenna module.

Wireless communication device including antenna modules and operating method of wireless communication device

A method of controlling a signal power of a received signal received by a wireless communication device, the method including: measuring the signal power of the received signal at a plurality of time points in response to a gain control signal; calculating a variance of the signal power of the received signal at least some time points of the plurality of time points; and controlling the signal power of the received signal based on a gain level determined according to the variance of the signal power of the received signal.

Wireless communication device for controlling signal power of received signal and operating method thereof

The present disclosure relates to an apparatus for wireless communication. The wireless communication apparatus comprises a baseband processor and a controller. The baseband processor is configured to generate state information about a channel of the wireless communication by processing a baseband signal. The controller is configured to activate a low power operation in a first channel state, where a channel quality is reduced compared to than a second channel state, based on the state information.
