Terminal for repeating through MBS communication network and method of repeating using the same

摘要

There is provided a method where a terminal amplifies an MBS signal that the terminal receives using a terminal in an MBS service, transmits the amplified signal to another terminal and controls it in order to overcome the fact it is not possible to provide high quality contents over a broad area due to interference signals between MBS zones, a terminal is used as a repeater at MBS transmission time only, and an output of a repeating signal of the terminal is controlled so that an excessive interference signal for another MBS area is not generated when the terminal operates as a repeater.

1. A terminal for receiving contents through a multicast and broadcasting service (MBS) communication network consisting of at least one base station (BS), the terminal for repeating through the MBS communication network comprising:
a receiver to receive a wireless signal for the contents from a BS constituting the MBS communication network; a signal processor to amplify or convert the received wireless signal; and a transmitter to repeat the processed wireless signal and to transmit the processed wireless signal to an adjacent BS or terminal in the MBS communication network, wherein the signal processor includes:
an interference signal extractor to extract a level of an interference signal other than the signal for the contents to be provided among the received wireless signal;a signal amplifying unit to amplify the received wireless signal; anda repeating controller to determine whether the received wireless signal is to be retransmitted based on the level of the interference signal, enable the amplifying unit to amplify the signal for the MBS zone among frames included in the received wireless signal and transfer the amplified signal to the transmitter, when the level of the extracted interference signal is found to be smaller than a predetermined threshold value, and the repeating controller controls a transmission gain of the signal transmitted from the transmitter in consideration of the level of the interference signal so that interference does not occur in another adjacent MBS communication network that generates the interference signal, wherein the terminal consumes the received wireless signal and at the same time retransmits the received wireless signal, when the terminal is in an MBS transmission mode.
