January 2016 doc.: IEEE 802.15-16-0066-00-003e Proposal for IEEE802.15.3e Subframe Padding (CID 1041) January 18, 2016 Submission Slide 3 Various Authors (TG3e Proposal)
January 2016 doc.: IEEE 802.15-16-0066-00-003e Recap During the conference calls in December 2015, it is determined that: 32 bit padding for subframes should be mandatory 64 bit or 128 bit padding can be optionally used and the capability should be signaled Submission Slide 4 Various Authors (TG3e Proposal) Various Authors (TG3e Proposal)
January 2016 doc.: IEEE 802.15-16-0066-00-003e Capability Signaling In the HRCP DEV Capability, HRCP PPC Capability, and HRCP pair Capability, allocate 2 bits for Supported unit of Subframe Padding subfield. Table 6-x Supported unit of Subframe Padding field 1 bit 1 bit 128 bit unit of padding supported 64 bit unit of padding supported Proposed Text: The Supported unit of Subframe Padding field indicates the unit of the subframe padding that can be received by the DEV as defined in Table 6- x. Each field shall be set to 1 for supported capability, and otherwise set to 0. 32 bit unit of padding is mandatory and it is not necessary to signal the 32 bit capability Submission Slide 5 Various Authors (TG3e Proposal) Various Authors (TG3e Proposal)
January 2016 doc.: IEEE 802.15-16-0066-00-003e Subframe Padding Propose to add following text in 7.8.3 HRCP aggregation: Padding octets shall be appended to each subframe except for the last subframe in the aggregated frame to make the subframe a multiple of n bits in length, where n is the largest unit of subframe padding supported by both the transmitter and the receiver of the aggregated frame. 32 bit unit of padding is mandatory and other optionally supported padding unit is indicated by the Supported unit of Subframe Padding field in the HRCP PPC Capability, HRCP DEV Capability, and HRCP pair Capability. The content of these padding octets is not specified. The maximum size of the MAC frame body, pMaxFrameBodySize is a PHY dependent parameter that indicates the size of the MAC frame body including frame payload(s), MAC subheader(s), and padding octets in the aggregated frames, and FCS(s) The Payload Length field is used to determine the length of the payload before coding, not including the FCS and padding octets.
