Wireless transmitting and receiving unit for providing service or activity in wireless local access network
Disclosed are a wireless transmitting and receiving unit for supporting an AP-based social communication service or activity, and a communication method thereof. A communication method of a wireless transmitting and receiving unit (WRTU), according to one embodiment disclosed in the present invention, includes the steps of: receiving a beacon signal, which contains service or activity identification information and information on a communication scheme, from an access point (AP); selecting the service or activity on the basis of the identification information; and performing an operation corresponding to the communication scheme when the service or activity is selected, wherein the communication scheme is designated to a first scheme for transmitting data frames to and receiving data frames from another wireless transmitting or receiving unit, which has selected the service or activity, or to a second scheme for receiving data frames from the access point.
1. A communication method of a Wireless Transmit/Receive Unit (WTRU), the communication method comprises:
receiving, from an Access Point (AP), a beacon signal including identification (ID) information of a service or activity, communication format information related to the identification information, and social zone information,
wherein the social zone information indicates time period of a social zone and a communication format used in the social zone;
selecting the service or activity based upon the ID information,
wherein the communication format is set to a first format when a first ID is selected and the communication format is set to a second format when a second ID is selected;
communicating with another WTRU to exchange a data frame in a first social zone based on the selected service or activity when the communication format is set to the first format, and
communicating with the AP to exchange a data frame in a second social zone based on the selected service or activity when the communication format is set to the second format.
2. The method of claim 1 , wherein the beacon signal further includes information on a radio resource of the service or activity.
3. The method of claim 2 , wherein the information on a radio resource of the service or activity includes an offset time, a length, an interval, and a system parameter.
4. The method of claim 3 , wherein the system parameter includes communication protocol information and information on the communication format.
5. The method of claim 4 , wherein the system parameter further includes information on a host device.
6. The method of claim 2 , wherein the information on a radio resource of the service or activity includes information on a frequency band.
7. The method of claim 1 , wherein the service or activity is associated with a Social Network Service (SNS).
8. A Wireless Transmit/Receive Unit (WTRU) comprising:
a transmitter configured to transmit radio signals to an external device;
a receiver configured to receive radio signals from the external device; and
a controller configured to control the transmitter and receiver,
wherein the controller is further configured to:
control the receiver to receive, from an Access Point (AP), a beacon signal including identification (ID) information of a service or activity, communication format information related to the identification information, and social zone information,
wherein the social zone information indicates time period of a social zone and a communication format used in the social zone;
select the service or activity based upon the ID information,
wherein the communication format is set to a first format when a first ID is selected and the communication format is set to a second format when a second ID is selected;
control the transmitter and receiver to communicate with another WTRU to exchange a data frame in a first social zone based on the selected service or activity when the communication format is set to the first format, and
control the transmitter and receiver to communicate with the AP to exchange a data frame in a second social zone based on the selected service or activity when the communication format is set to the second format.
9. The Wireless Transmit/Receive Unit (WTRU) of claim 8 , wherein the beacon signal further includes information on a radio resource of the service or activity.
10. The Wireless Transmit/Receive Unit (WTRU) of claim 9 , wherein the information on a radio resource includes an offset time, a length, an interval, and a system parameter.
11. The Wireless Transmit/Receive Unit (WTRU) of claim 10 , wherein the system parameter includes communication protocol information and information on the communication format.
12. The Wireless Transmit/Receive Unit (WTRU) of claim 11 , wherein the system parameter further includes information on a host device.
13. The Wireless Transmit/Receive Unit (WTRU) of claim 9 , wherein the information on a radio resource of the service or activity includes information on a frequency band.
14. The Wireless Transmit/Receive Unit (WTRU) of claim 8 , wherein the service or activity is associated with a Social Network Service (SNS).
