Abstract
A method of a first device which performs ranging by using an ultra-wide band (UWB) and the first device are provided. The method of the first device includes performing ranging with a second device in a first ranging round among a plurality of ranging rounds included in a first ranging block, determining whether to perform hopping, based on a result of the performing of the ranging, when it is determined to perform the hopping, determining an index of a second ranging round for performing ranging with a second device, based on a random-number generation function, and performing the ranging with the second device in the second ranging round of a second ranging block.
Claims20
A method of operating a first device which performs ranging by using an ultra-wide band (UWB), the method comprising:
- performing ranging with a second device in a first ranging round in a first ranging block;
- and
- performing ranging with the second device in a second ranging round included in a second ranging block,
- wherein in case that a hopping mode is enabled, an index of the second ranging round is identified based on a random-number generation function using an index of the second ranging block and a value related to a ranging session, and an index of the first ranging round and the index of the second ranging round are different values.
A method of operating a second device which performs ranging by using an ultra-wide band (UWB), the method comprising:
- performing ranging with a first device in a first ranging round in a first ranging block;
- and
- performing ranging with the first device in a second ranging round included in a second ranging block,
- wherein in case that a hopping mode is enabled, an index of the second ranging round is identified based on a random-number generation function using an index of the second ranging block and a value related to a ranging session, and an index of the first ranging round and the index of the second ranging round are different values.
A first device which performs ranging by using an ultra-wide band (UWB), the first device comprising:
- a communicator;
- and
- at least one processor configured to:
- perform ranging with a second device in a first ranging round in a first ranging block, and
- perform ranging with the second device in a second ranging round included in a second ranging block,
- wherein in case that a hopping mode is enabled, an index of the second ranging round is identified based on a random-number generation function using an index of the second ranging block and a value related to a ranging session, and an index of the first ranging round and the index of the second ranging round are different values.
