Abstract
A method performed by a first ultra-wideband (UWB) device in a wireless communication system is provided. The method may include: transmitting, to a second UWB device, a request message for fetching service related information for at least one service; and in case that the at least one service is supported by the second UWB device, receiving, from the second UWB device, a response message including the service related information for the at least one service.
Claims7
A method performed by a first ultra-wide band (UWB) device in a wireless communication system, the method comprising:
- transmitting, to a second UWB device, an out of band (OOB) request message for fetching service related information for at least one service, the OOB request message including a service identifier (ID) and a number of services;
- and
- receiving, from the second UWB device, an OOB response message including service related information corresponding to the service ID and the number of services,
- wherein the service related information corresponding to the service ID and the number of services corresponds to information for all services in case that a value of the service ID is set to zero.
A method performed by an ultra-wideband (UWB) device in a wireless communication system, the method comprising:
- broadcasting an advertisement message including information indicating a presence of UWB service information in at least one of the advertisement message, an extended advertisement message or a scan response message and information indicating UWB service information availability using an out of band (OOB) connection,
- wherein the UWB service information includes a bitmask of UWB services,
- wherein a bit of the bitmask is mapped to a service identifier (ID), and
- wherein a value of the bit indictes whether a service corresponding to the service ID is supported.
A first ultra-wideband (UWB) device in a wireless communication system, the first UWB device comprising:
- a transceiver;
- and
- at least one processor coupled to the transceiver and configured to:
- transmit, to a second UWB device, an out of band (OOB) request message for fetching service related information for at least one service, the OOB request message including a service identifier (ID) and a number of services;
- and
- receive, from the second UWB device, an OOB response message including service related information corresponding to the service ID and the number of services,
- wherein the service related information corresponding to the service ID and the number of services corresponds to information for all services in case that a value of the service ID is set to zero.
