a controller configured to control to transmit the UE management information to a base station,
wherein, according to resource allocation performed by the base station based on the UE management information, the controller is configured to, in case of subcarrier intervals of two or more frequency bands covered by the phase array antenna being the same, perform beam training at a same symbol timing in the two or more frequency bands, and, in case of the subcarrier intervals being different from each other, perform the beam training at a time corresponding to a longest symbol length among symbol lengths in the two or more frequency bands.

2. The electronic device of claim 1 , wherein the UE management information is included in UE capability information which is periodically transmitted to the base station by the electronic device.

3. The electronic device of claim 1 , wherein the UE management information comprises information about:
an index of a first antenna, among the plurality of antennas, capable of receiving a first frequency band, mapped to the first frequency band; and
an index of a second antenna, among the plurality of antennas, capable of receiving a second frequency band, mapped to the second frequency band.

4. The electronic device of claim 1 , wherein the plurality of antennas of the phase array antenna comprise a first antenna and a second antenna,

wherein the UE management information comprises information about:
a first index indicating first frequency bands covered by the first antenna in the index mapping table; and
a second index indicating second frequency bands covered by the second antenna in the index mapping table.

5. The electronic device of claim 1 , wherein the UE management information comprises information about a plurality of frequency bands covered by an antenna among the plurality of antennas of the phase array antenna transmitted to the base station on the basis of transmission configuration indicator (TCI) state information.

6. The electronic device of claim 1 , wherein the UE management information is transmitted by using at least one of a radio resource control (RRC) message and system information.

7. The electronic device of claim 1 , wherein UE management information comprises information about a plurality frequency bands covered by the plurality of antennas of the phase array antenna, respectively, and
wherein the UE management information comprises information about combinations of the frequency bands through which the plurality of antennas are configured to receive respective signals from the base station.

8. The electronic device of claim 1 , wherein the antenna is configured to receive a cell state information-reference signal (CSI-RS) that the base station transmits to the electronic device based on the UE management information.

9. The electronic device of claim 1 , wherein the controller is configured to transmit the UE management information to the base station after a radio resource control (RRC) connection between the electronic device and the base station is established.

10. The electronic device of claim 1 , wherein the plurality of antennas are configured such that based on at least one first antenna performing a beamforming based on a first phase/amplitude set, a wireless signal received by at least one second antenna is changed based on the first phase/amplitude set.
