Abstract:
A data transmission apparatus in a communication system includes a reception unit configured to receive terminal information from a plurality of terminals through a new frequency band for transmission and reception of data between the plurality of terminals and an AP (access point); a determination unit configured to determine access timing of the terminals to the AP by using the terminal information, and generate terminal access information including information on the access timing; and a transmission unit configured to transmit the terminal access information and beacon frames to the terminals, wherein the terminals access the AP and transmit data frames to the AP, at the access timing based on the beacon frames.
Abstract:
A data transmission apparatus in a communication system includes a reception unit configured to receive adjacent terminal information from a plurality of terminals through a new frequency band for transmission and reception of data between the terminals and one AP (access point); a verification unit configured to identify positions of the terminals within a service coverage of the AP through the adjacent terminal information, group the terminals into terminal groups through position-based grouping, and verify transmission possible times to the AP, in terminals included in the terminal groups; and a transmission unit configured to transmit the transmission possible times to the terminals included in the terminal groups through beacon frames in the AP, wherein, as the transmission possible times for the terminal groups, different time intervals are allocated in a beacon interval of the beacon frames.
Abstract:
A resource allocation apparatus in a communication system includes an identification unit configured to identify a new frequency band for transmission and reception of data between a plurality of terminals and a first access point, and identify a first frequency band which is being used by a second access point in the new frequency band; a setting unit configured to divide the new frequency band into sub bands of a basic frequency band, and set priorities of the sub bands; and an allocation unit configured to allocate the sub bands in correspondence to the priorities, for transmission and reception of data between the plurality of terminals and the first access point.
