1 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 1 Clarification for the definition of TSPEC parameters Yoshihiro Ohtani Sharp Corporation 14 March 2002

2 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 2 Clear Definition for TSPECs It seems that the meanings of some TSPEC parameters are not clearly defined. Some TSPEC parameters define the characteristics of the stream itself, others define the requirement for HC scheduling. It may be better to classify which TSPEC parameters define the characteristics of the stream itself. Clear Definition for TSPECs should be addressed for the interoperability.

4 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 4 Definition of Interarrival Interval MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Interarrival Interval = E{ Tin ( i+1 ) - Tin ( i ) } This parameter defines the characteristics of the stream itself

5 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 5 Definition of Nominal MSDU Size MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Nominal MSDU Size = E{ B( i ) } This parameter defines the characteristics of the stream itself

6 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 6 Definition of Maximum Burst Size MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Maximum Burst Size = Max{ B( i ) } This parameter defines the characteristics of the stream itself

7 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 7 Definition of Minimum Data Rate MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Minimum Data Rate = Min{ }, for some N This parameter defines the characteristics of the stream itself B(i+1) + + B(i+N) Tin (i+N) - Tin (i)

8 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 8 Definition of Mean Data Rate MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Mean Data Rate = E{ }, for some N This parameter defines the characteristics of the stream itself B(i+1) + + B(i+N) Tin (i+N) - Tin (i)

9 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 9 Definition of Delay Bound MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Delay Bound = Max[ Tout ( i ) - Tin ( i ) ] This parameter does not define the characteristics of the stream itself This parameter defines the requirement for HC scheduling

10 doc.: IEEE 802.11-02/259r0 Submission March 2002 Yoshihiro Ohtani, SharpSlide 10 Definition of Jitter Bound MAC MSDU(i) t = Tin(i) PHY Sender STA LLC MAC MSDU(i) t = Tout(i) PHY Receiver STA MSDU(j) t = Tin(j) MSDU(j) t = Tout(j) B(i) bytesB(j) bytes LLC Jitter Bound = Max [ { Tout ( i ) - Tin ( i ) }-{ Tout ( j ) - Tin ( j ) } ] This parameter does not define the characteristics of the stream itself This parameter defines the requirement for HC scheduling
