COMMUNICATION DEVICE AND COMMUNICATION METHOD

Title:

COMMUNICATION DEVICE AND COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2021/024559

Kind Code:

A1

Abstract:

Provided is a communication device which is equipped with a plurality of antenna elements, and which, with a circuit scale suppressed, performs wireless communication in a high-frequency band.　The communication device comprises a communication unit for transmitting/receiving a wireless signal using the plurality of antenna elements, and a control unit for controlling, on the basis of control information received from the outside, compensation for the degradation of communication quality in the communication unit. The communication unit includes a plurality of wireless interfaces, and a delay compensation unit for compensating for a delay of the wireless interface. The control unit determines, on the basis of capability information exchanged with a communication partner, whether or not to execute the compensation.
