Abstract: A method for controlling radio resource allocation for a low power sensor communication service by a relay coordinator. The method may include configuring a frame that includes a Contention Access Period (CAP) offset and a Contention Free Period (CFP) offset of variable sizes, and an Relay Period (RP) that relays data between a Personal Area Network (PAN) coordinator and one or more lower hierarchical devices; and generating a beacon frame that includes information of the frame configuration, and transmitting the beacon frame to the one or more lower hierarchical devices; and transmitting data, which is received from the one or more lower hierarchical devices through the CFP, to the PAN coordinator through the RP, or transmitting data, which is received from the PAN coordinator through the RP, to lower hierarchical nodes through the CFP.
