BW-REQCH Message Boosting Level

Goal of Proposal § Problem Definition • D 4 defines power control for BW REQ CH • BS broadcasts “target SINR” for BW REQ CH for both MSG & Preamble parts • In this case, performance of Data & Preamble is unbalanced § Goal • To find proper power boosting level for MSG part over Preamble • To obtain “Balanced performance” satisfying requirements 2/#NN

Requirements § Preamble MP < 1% § Message MP ~1% § Preamble FA < 0. 1% § Message PER < 0. 1% 3/#NN

Message Boosting Level, Ped-B 3 km/h, 2 Rx Missing Prob. 10, 000% 1, 000% 3 d. B or 4 d. B looks good But, 3 d. B case has 0. 5 d. B link gain 0, 100% 0, 010% -8, 0 -7, 0 MP_Msg. Bst_0 d.

Conclusion § From the simulation results, we can conclude that § Power boosting 3 d. B of MSG part over Preamble is recommended • Boosting 3 d. B has 0. 5 d. B link gain over 4 d. B case • Since MSG part is not mandatory, 2% MP would be okay 5/#NN
