Abstract
An apparatus configured to perform one or more of an advertising operation, a scanning operation, and a Narrowband-aided multi-millisecond (NBA-MMS) ranging operation for a first wireless device in a first timing interval and perform one or more of an advertising operation, a scanning operation, and an NBA-MMS ranging operation for a second wireless device in the first timing interval or a successive timing interval.
Claims20
An apparatus comprising processing circuitry coupled to memory, the processing circuitry configured to:
- perform one or more of an advertising operation, a scanning operation, and a Narrowband-aided multi-millisecond (NBA-MMS) ranging operation for a first wireless device in a first timing interval;
- and
- perform one or more of an advertising operation, a scanning operation, and an NBA-MMS ranging operation for a second wireless device in the first timing interval or a successive timing interval.
An apparatus comprising processing circuitry coupled to memory, the processing circuitry configured to:
- perform a first Narrowband-aided multi-millisecond (NBA-MMS) ranging operation for a first wireless device in a first ranging interval;
- perform a second NBA-MMS ranging operation for the first wireless device in a second ranging interval successive to the first ranging interval;
- and
- perform at least one of the following:
- randomly select an ultra-wideband (UWB) preamble for one or more of the first ranging interval and the second ranging interval, the UWB preamble being randomly selected from a set of N preamble sequences, wherein N is a positive integer;
- or
- add a dither delay period to each of the first and second ranging intervals, where the amount of the dither delay period is randomly selected for each of the first and second ranging intervals.
