doc.: e Submission May 2010 Slide 2 ABT update in current draft In draft - (P166 L34~35) On receipt of an DSME handshake command indicating an DSME deallocation notify, … the device updates its ABT to reflect the neighbors deallocated DSME. - (P166 L21~24) On receipt of an DSME handshake command indicating an DSME deallocation reply, … the device updates its ABT to reflect all the neighbors deallocated DSME. A device updates its ABT to reflect the neighbors deallocated DSME slots only when it receives the DSME deallocation reply command or DSME deallocation notify command. Both commands are transmitted by broadcasting. So its probable for the device missing those commands. DSME dealloc req DSME dealloc rep DSME dealloc nof

doc.: e Submission May 2010 Slide 3 Potential problem If the device misses those commands, it has no chance to update its ABT correctly in the future. Although therere lots of DSME slots in a superframe, accumulation of that problem will also influence the DSME allocation and is nearly impossible to recover. For example, A and B have common vacant slots to communication in fact, but according to ABTs they wont allocate them for each other. ?: non-updated slots, i.e. the slots that were not updated correctly to reflect deallocation. The non- updated slots are selected by the device. Yellow, Orange and Blue: the unavailable slots.

doc.: e Submission May 2010 Slide 4 Suggested remedy Add a pair of commands ABT update request ABT update reply The device broadcasts ABT update request containing the non-updated slots to its neighbors. If the non-updated slots are being used by the neighbor, the neighbor sends back ABT update reply. If not, the neighbor ignores the command and the device updates ABT.
