<month year> doc.: IEEE < e> Project: IEEE P Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [message sequence charts for RLS] Date Submitted: [9 November 2017] Source: [Billy Verso] Company [Decawave Ltd.] Address [Peter Street, Dublin 8, Ireland] Voice:[ ], [billy.verso (at)] Re: [message sequence charts for Ranging and Location Services for ULI] Abstract: [Capture MSC specifying how the RLS function operates in TG12 ULI] Purpose: [Advance the work of defining the ranging and localisation support (RLS) functionality for the TG12 ULI specification] Notice: This document has been prepared to assist the IEEE P It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

2 The aim of this presentation:
Using MSC to describe the operation of the Ranging and Location Support (RLS) function within the ULI Stimulate discussion on the primitives and message flows to explore and ultimately specify the operation of the RLS function.

3 Single-Sided Two-Way Ranging:
Referring to a-model-of-ss-twr-for-the-uli We see that both direct and piggy-back methods are envisaged Direct: the RLS is generating and consuming the ranging frames. Piggy-backed: The RLS adds IEs to data frames as they are passing into the MAC, and consumes/removes them from received frames coming from the MAC. Next sheets examine these to methods using message sequence charts to capture a possible interaction model.

4 MSC for direct SS-TWR:

5 MSC for piggy-backed SS-TWR:
Note: This is 1st half of the SS-TWR, completed by receiving a frame providing the RLS IE with TREPLY and calculating the TOF
