A method of receiving multicast transmission from a base station includes receiving allocation information about a feedback channel including a plurality of resources shared by another terminal, determining feedback information based on an estimated channel with the base station, determining a plurality of transmission power levels respectively corresponding to the plurality of resources based on the feedback information, and transmitting channel feedback to the base station on the feedback channel based on the plurality of transmission power levels.

Method for multicast transmission based on channel feedback

An operating method of a wireless communication device performing an interference whitening operation includes obtaining first channel state information of the wireless communication device, selecting a selected mode from among a plurality of modes related to the interference whitening operation, the selected mode corresponding to the first channel state information, obtaining channel performance information according to the selected mode, and updating a value function expected value based on the first channel state information, the selected mode, and the channel performance information.

Wireless communication device for performing interference whitening operation and operating method thereof

A method of controlling transmission power for wireless communication includes obtaining detected transmission power; generating a state variable and a reward variable of a reinforcement learning model based on the detected transmission power, threshold transmission power, and a channel state; and training a reinforced learning agent based on the state variable and the reward variable to output an action variable of the reinforcement learning model representing the transmission power.

Apparatus and method for controlling transmission power based on reinforcement learning

Disclosed are a communication device for performing beamforming and an operating method thereof. The communication device includes: an antenna array configured to simultaneously form a first vertical beam and a second vertical beam for an arbitrary time; a transceiver configured to transmit and receive a signal using a double beam including the first vertical beam and the second vertical beam; and a processor configured to determine a first optimal vertical tilting angle of the first vertical beam based on Inter-Beam Interference (IBI) of the second vertical beam, and determine a second optimal vertical tilting angle of the second vertical beam based on the IBI of the first vertical beam.

Communication device performing beam-forming and operating method thereof

The present disclosure provides a method for a multi-subscriber identity module (SIM) wireless communication. The method includes receiving a communication request, performing a first wireless communication, and performing a second wireless communication. Receiving a communication request by a second SIM while in wireless communication is based on a first SIM is performed via a plurality of antennas. Performing a first wireless communication is based on the first SIM communicating via a first antenna group that is a portion of the plurality of antennas, in response to a number of antennas used for wireless communication based on the first SIM and the second SIM that is greater than a number of available antennas of a terminal. Performing a second wireless communication is based on the second SIM via a second antenna group while the first wireless communication is performed and the second group is different from the first antenna group.
