Abstract
Methods and apparatuses of transmitting a beacon using fragmentation are disclosed. One of the methods includes configuring a beacon in a manner that a schedule block selected for a specific wireless device (deice) only is included in an information element by a coordinator and transmitting the configured beacon to the specific wireless station directionally. Accordingly, an overhead of a beacon can be reduced in a manner of transmitting information specified to a station using a directional beacon or transmitting the beacon by dividing information contained in the beacon into several fragments.
Claims9
In a wireless communications system, a method of transmitting beacon signals including static information and dynamic information to each of a plurality of wireless stations, said method comprising:
- dividing the static information into a plurality of static information fragments;
- generating a sequence of beacon signals, each including dynamic information and at least one of said static information fragments;
- and
- transmitting the sequence of beacon signals omni-directionally to the plurality of wireless stations such that all of the static information is transmitted when all of the beacon signals have been transmitted.
In a wireless communications system that includes a coordinator and a plurality of wireless stations, a method of receiving both static information and dynamic information from the coordinator, said method comprising:
- receiving a sequence of beacon signals at one of the plurality of wireless stations, each of the beacon signals having been transmitted omni-directionally, each of the beacon signals including dynamic information and a fragment of the static information, such that all of the static information is received upon receiving the sequence of beacon signals;
- and
- communicating with the coordinator in accordance with the information received on the sequence of beacon signals.
In a wireless communications system that includes a plurality of wireless stations and a coordinator, an apparatus in one of said wireless stations for receiving and processing static and dynamic information, the apparatus comprising:
- a communication module configured to transmit and receive data to and from at least one other wireless station or the coordinator;
- a beacon management unit configured to receive a sequence of beacon signals transmitted omni-directionally from the coordinator and to analyze static and dynamic information contained on the sequence of beacon signals, wherein each of the beacon signals contains dynamic information and a fragment of the static information such that all of the static information is received when the sequence of beacon signals is received;
- and
- a controller configured to control the exchange of data with the at least one other wireless station or the coordinator based on the information contained on the beacon signals.
In a wireless communications system that includes a plurality of wireless stations, an apparatus for transmitting static and dynamic information, said apparatus comprising:
- a communication module configured to transmit and receive data to and from the wireless stations;
- a beacon management unit configured to generate a sequence of beacon signals and configured to omni-directionally transmit the sequence of beacon signals to the wireless stations, each of the beacon signals containing dynamic information and a fragment of the static information such that all of the static information is transmitted when all of the beacon signals are transmitted;
- and
- a controller configured to control the beacon management unit to generate and to omni-directionally transmit the sequence of beacon signals.
