Abstract: An electronic device includes a processing circuit configured to: receive information about a number N of candidate transmit beams from a user device, wherein N is an integer greater than 1; select from the N candidate transmit beams a transmit beam for sending downlink information to the user device; and determine, on the basis of the selected transmit beam, a transmission configuration indication (TCI) state, and send the TCI state to the user device. The electronic device, the wireless communication method and the computer readable storage medium enable a network-side device to notify the user device of the information about transmit beams. In this way, the user device can determine, according to the transmit beam of the network-side device, a proper receiving beam so as to improve the gain of the system.
