Method and apparatus for providing regulatory information in UWB system
In an embodiment, a method for providing regulatory information by a first device in an ultra-wide band (UWB) system is provided. The method includes indicating availability of the regulatory information to a second device; and providing the regulatory information to the second device based on the availability of the regulatory information, wherein the regulatory information includes at least one of a confidence level indicating a source of the regulatory information, a country code, a time stamp.
1. A method for providing ultra-wide band (UWB) regulatory information by a first device in a UWB system, comprising:
indicating availability of the UWB regulatory information to a second device;
receiving a request message for requesting the UWB regulatory information from the second device based on the availability of the UWB regulatory information; and
transmitting a response message including the UWB regulatory information to the second device in response to the request message,
wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, a country code, a time stamp of the UWB regulatory information, and a list of regulatory channel and power information element.
2. The method of claim 1 , wherein the regulatory channel and power information element includes at least one of first channel information, information about a number of consecutive channels, and maximum power information.
3. The method of claim 1 , wherein the source information indicates one of a user setting, a satellite navigation system, a cellular system, and configuration via another device.
4. The method of claim 1 , wherein the indicating the availability of the UWB regulatory information comprises:
indicating the availability of the UWB regulatory information using one of an advertisement message, an extended advertisement message, and a scan request and a scan response.
5. A first device in an ultra-wide band (UWB) system, comprising:
a transceiver; and
at least one processor configured to control the transceiver to:
indicate availability of UWB regulatory information to a second device,
receive a request message for requesting the UWB regulatory information from the second device based on the availability of the UWB regulatory information, and
transmit a response message including the UWB regulatory information to the second device in response to the request message,
wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, a country code, a time stamp of the UWB regulatory information, and a list of regulatory channel and power information element.
6. The first device of claim 5 , wherein the regulatory channel and power information element includes at least one of first channel information, information about a number of consecutive channels, and maximum power information.
7. The first device of claim 5 , wherein the source information indicates one of a user setting, a satellite navigation system, a cellular system, and configuration via another device.
8. The first device of claim 5 , wherein the at least one processor is further configured to indicate the availability of the UWB regulatory information using one of an advertisement message, an extended advertisement message, and a scan request and a scan response.
9. A second device in an ultra-wide band (UWB) system, comprising:
a transceiver; and
at least one processor configured to control the transceiver to:
identify availability of UWB regulatory information indicated by a first device,
transmit a request message for requesting UWB regulatory information to the first device based on the availability of the UWB regulatory information, and
receive a response message including the UWB regulatory information from the first device in response to the request message,
wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, a country code, a time stamp of the UWB regulatory information, and a list of regulatory channel and power information element.
10. The second device of claim 9 , wherein the regulatory channel and power information element includes at least one of first channel information, information about a number of consecutive channels, and maximum power information.
11. The second device of claim 9 , wherein the source information indicates one of a user setting, a satellite navigation system, a cellular system, and configuration via another device.
12. The second device of claimer 9 , wherein the availability of the UWB regulatory information is indicated by using one of an advertisement message, an extended advertisement message, and a scan request and a scan response.
13. A method for receiving ultra-wide band (UWB) regulatory information by a second device in a UWB system, comprising:
identifying availability of the UWB regulatory information indicated by a first device;
transmitting a request message for requesting the UWB regulatory information to the first device based on the availability of the UWB regulatory information; and
receiving a response message including the UWB regulatory information from the first device in response to the request message,
wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, a country code, a time stamp of the UWB regulatory information, and a list of regulatory channel and power information element.
14. The method of claim 13 , wherein the regulatory channel and power information element includes at least one of first channel information, information about a number of consecutive channels, and maximum power information.
15. The method of claim 13 , wherein the source information indicates one of a user setting, a satellite navigation system, a cellular system, and configuration via another device.
16. The method of claim 13 , wherein the availability of the UWB regulatory information is indicated by using one of an advertisement message, an extended advertisement message, and a scan request and a scan response.
