IEEE /r1 Submission March, 2005 Slide 2 Yozo Shoji, NICT Ad-hoc information distribution with P-P network extension Proposal of Channel allocation and Frame format concept for mmW WPAN application

IEEE /r1 Submission March, 2005 Slide 3 Yozo Shoji, NICT Requirements for mmW WPAN channel allocation and frame format Support of very broadband transmission in selective channels Support of various applications whose required data rate is changed widely Coexistence of digital communication channels and through repeated channels

IEEE /r1 Submission March, 2005 Slide 4 Yozo Shoji, NICT Concept of channel allocation for mmW WPAN Multiple sub-carrier channels based on FDMA/TDMA coexistence format Common standardized access channels based on time- synchronized multi-carrier TDMA Optional FDM/FDMA extension channels, in which digital channels and through-repeated channels coexist

IEEE /r1 Submission March, 2005 Slide 5 Yozo Shoji, NICT Frame format of common standardized channel Frame format of Common Standardized access channels is basically based on MAC frame PNC allocates not only contention free time slot but also optional FDM/FDMA extension channel to DEV on demand All the information about channel allocation is broadcasted in the initiation of contention free period

IEEE /r1 Submission March, 2005 Slide 6 Yozo Shoji, NICT Frame format of optional FDM/FDMA extension channel Frame format of digital modulated channels in the optional extension channels are the same as that of contention free period in MAC frame, but occupied by only one specific DEV Frame format of through-repeated channels in the optional extension channels are not specified Not Specified

IEEE /r1 Submission March, 2005 Slide 7 Yozo Shoji, NICT Broadband ad-hoc meeting in a office-room Particular case when one PNC exists and occupies a large number of optional FDMA channels for data broadcasting Common standardized band uses TDMA based channels working on MAC, and is used for joining and leaving the piconet control, allocating optional FDMA channels, and relatively low-rate data communications Common Standardized Band Optional FDMA Band
