Apparatus and method for operating analog beam in a beam division multiple access system

An apparatus for operating an analog beam using a hybrid beam-forming structure having a small number of digital chains provided in a digital stage, and transmitting and receiving a signal in a Time Division Multiple Access (TDMA) scheme, the apparatus comprising:

• an analog beam-forming operating unit configured to change an analog beam for a counterpart device for which use of a next frame is to be permitted, upon receiving a request for using the next frame from at least one of multiple devices that transmit and receive signals in units of frames;
• and
• a communication unit configured to transmit information indicating that the analog beam is changed to permit the use of the next frame by the counterpart device to the multiple devices.

A wireless terminal for transmitting and receiving a signal in units of frames supporting a Time Division Multiple Access (TDMA) scheme to and from a Base Station (BS) with a hybrid beam-forming structure having a small number of digital chains provided in a digital stage, the wireless terminal comprising:

• a communication unit configured to send a request for using a next frame to the BS in an uplink transmission period of a current frame and to receive information about a counterpart device for which use of the next frame is permitted and information about an analog beam to be changed for the use of the next frame from the BS in a downlink transmission period of the next frame;
• and
• a control unit configured to control the communication unit to transmit and receive a signal to and from the BS in the uplink transmission period and the downlink transmission period of the next frame by using the analog beam recognized based on the information about the analog beam to be changed, if the use of the next frame is permitted by the information about the counterpart device.
