Abstract: A method of operating a network coordinator for a spatial reuse scheme includes receiving a reservation request for a time period for a data communication of a target transmitter/receiver pair that uses a directional antenna, searching for a time period reserved in advance for another transmitter/receiver pair, from a Channel Time Allocation Period (CTAP) that is a contention-free access period for the data communication, and reserving a time period for the target transmitter/receiver pair in the CTAP, so that the time period reserved for the target transmitter/receiver pair overlaps the time period reserved in advance for the other transmitter/receiver pair.

Abstract: Provided is a communication method of a coordinator in a wireless networks system that uses a reservation-based media access control (MAC). The communication method includes receiving, from a source device, a frame that requests a reservation resource for a relay device, to enable a frame that the source device transmits to a destination device to be relayed via the relay device, and allocating the reservation resource for the relay device, in response to the request.

Abstract: An apparatus and a method for reassembling a DOCSIS(Data-Over-Cable Service Interface Specifications) MAC(Media Access Control) frame in a cable modem having a plurality of receiving channels are provided to reassemble a DOCSIS MAC frame by extracting the DOCSIS MAC frame from MPEG2-TS packets. Downlink channel receiving modules(111,112) receive a RF signal, and outputs a MPEG2-TS packet signal. MAC frame reassembling buffer writing modules(121,122) store data to MAC frame reassembling buffers(141,142). MAC reassembling control modules(131,132) control a MPEG header and a point field. MAC frame reassembling butter reading modules(151,152) store one complete DOCSIS MAC frame to a MAC frame buffer. MAC frame buffer modules(161,162) store one complete DOCSIS MAC frame.
