    Abstract: Disclosed is a method of allocating radio resources, including: acquiring available channel information of a cognitive radio small cell; analyzing a channel characteristic based on the available channel information and dividing a required transmission rate of the cognitive radio small cell into required transmission rates for each available channel; and performing a power control for each available channel based on the divided required transmission rates for each available channel. The method of allocating radio resources may be performed under an interference environment in which a plurality of cognitive radio small cells is present and the plurality of cognitive radio small cells shares an available channel.

    Abstract: Disclosed are a low-power communication method and a low-power communication apparatus in a communication system. A low-power station may comprise a processor; a memory storing at least one instruction executable by the processor; a receiver for receiving a WUR PPDU according to the at least one instruction; and a transceiver for transmitting and receiving a legacy PPDU according to the at least one instruction, and the at least one instruction may be configured to cause the receiver to receive a WUR wake-up frame from the access point in an on-duration within a WUR duty cycle period; when the WUR wake-up frame is received, cause the processor to transmit a first signal requesting wake-up to the transceiver; and when the first signal is received, cause the transceiver to transition from a sleep state to a wake-up state at a TWT configured between the access point and the low-power station.
