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 first device in an ultra-wide band (UWB) system, comprising:
a transceiver; and
at least one processor configured to control the transceiver to:
receive, from a second device, an out-of-band (OOB) message including indication information for an availability of UWB regulatory information,
transmit, to the second device, a request message for requesting UWB regulatory information based on the indication information, and
receive, from the second device, a response message including the UWB regulatory information as a response to the request message,
wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, country code information, list information including a list of at least one regulatory channel and power information element, and number information indicating a number of the regulatory channel and power information element in the list information.
2. The first device of claim 1 , wherein the indication information indicates whether the UWB regulatory information is available via an OOB.
3. The first device of claim 2 , wherein, in case that the indication information indicates that the UWB regulatory information is available via OOB, the response message is received via the OOB.
4. The first device of claim 1 , wherein the OOB message is one of an advertisement message, a bluetooth low energy (BLE) advertisement message, an extended advertisement message, a scan request message or a scan response message.
5. The first device of claim 1 , wherein the regulatory channel and power information element includes channel information, and maximum power information.
6. The first device 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.
7. A second device in an ultra-wide band (UWB) system, comprising: a transceiver; and at least one processor configured to control the transceiver to: transmit an out-of-band (OOB) message including indication information for an availability of UWB regulatory information, receive, from the second device, a request message for requesting UWB regulatory information based on the indication information, and transmit, to the second device, a response message including the UWB regulatory information as a response to the request message, wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, country code information, list information including a list of at least one regulatory channel and power information element, and number information indicating a number of the regulatory channel and power information element in the list information.
8. The second device of claim 7 , wherein the indication information indicates whether the UWB regulatory information is available via an OOB.
9. The second device of claim 8 , wherein, in case that the indication information indicates that the UWB regulatory information is available via OOB, the response message is transmitted via the OOB.
10. The second device of claim 7 , wherein the OOB message is one of an advertisement message, a bluetooth low energy (BLE) advertisement message, an extended advertisement message, a scan request message or a scan response message.
11. The second device of claim 7 , wherein the regulatory channel and power information element includes channel information, and maximum power information.
12. The second device of claim 7 , wherein the source information indicates one of a user setting, a satellite navigation system, a cellular system, and configuration via another device.
13. A method performed by a first device in an ultra-wide band (UWB) system, the method comprising:
receiving, from a second device, an out-of-band (OOB) message including indication information for an availability of UWB regulatory information;
transmitting, to the second device, a request message for requesting UWB regulatory information based on the indication information; and
receiving, from the second device, a response message including the UWB regulatory information as a response to the request message,
wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, country code information, list information including a list of at least one regulatory channel and power information element, and number information indicating a number of the regulatory channel and power information element in the list information.
14. The method of claim 13 , wherein the indication information indicates whether the UWB regulatory information is available via an OOB.
15. The method of claim 14 , wherein, in case that the indication information indicates that the UWB regulatory information is available via OOB, the response message is received via the OOB.
16. The method of claim 13 , wherein the OOB message is one of an advertisement message, a bluetooth low energy (BLE) advertisement message, an extended advertisement message, a scan request message or a scan response message.
17. The method of claim 13 , wherein the regulatory channel and power information element includes channel information, and maximum power information.
18. 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.
19. A method performed by a second device in an ultra-wide band (UWB) system, the method comprising: transmitting an out-of-band (OOB) message including indication information for an availability of UWB regulatory information; receiving, from the second device, a request message for requesting UWB regulatory information based on the indication information; and transmitting, to the second device, a response message including the UWB regulatory information as a response to the request message, wherein the UWB regulatory information includes source information indicating a source of the UWB regulatory information, country code information, list information including a list of at least one regulatory channel and power information element, and number information indicating a number of the regulatory channel and power information element in the list information.
