(Marvell) doc.: IEEE 802.11-16/0037r1 Overview • Fact 1 about HE-SIGB: – – – – Consists of a common field, and multiple user-specific fields The length of common field can be varying per BW The length of the last user specific field may be different with the rest. Each field ends with 6 zero tail bits. • Fact 2 about HE-SIGB: – HE-SIGB (in each 20MHz) is encoded using BCC with common and user blocks separated in the bit domain. – Multiple MCS (MCS0~5) can be used for HE-SIGB, so the coding rate may be less than ½ by puncturing. • Question: how to puncture in HESIGB? Submission Slide 10 Yakun Sun, et. al. (Marvell) doc.: IEEE 802.11-16/0037r1 Puncturing for BCC • The two output bit streams of rate-1/2 BCC encoder are split into multiple “puncture patterns” and some bits are “stolen” to meet the coding rate. • Each field (both common and user-specific) is not an integer number of “puncturing patterns”. • How to puncture? Submission Slide 11 Yakun Sun, et. al. (Marvell) doc.: IEEE 802.11-16/0037r1 Puncturing for HESIGB Encoding • What if padding for each field to integer number of puncturing patterns? – – – • What if define each HESIGB field to be an integer numbers of puncturing patterns? – – • Not efficient may end up more HESIGB symbols Complicates both transmission and reception. Not allowed by the current SFD: “The last user information is immediately followed by tail bits (regardless of whether the number of users is odd or even) and padding bits are only added after those tail bits” Again, not efficient HESIGB is already long, and great efforts have been made to make it concise. It needs to support both rate 2/3 and ¾ the length of field must to be a multiple of 18bit very inflexible and insufficient. Continuous puncturing of all fields – Submission Very efficient and simple (see following slides) Slide 12 Yakun Sun, et. al. (Marvell) doc.: IEEE 802.11-16/0037r1 Continuous BCC Puncturing/Encoding • To simplify SIGB content design by supporting arbitrary length of each group, SIGB bits are continuously encoded. • Namely, the sequence of SIGB bits (after adding tail bits for each field) is passed through one Rate-1/2 BCC encoder continuously. – 6 tail bits in the end of each field reset the convolutional encoder, so it is equivalent to encode each field with individual Rate-1/2 encoder. – This does not conflict with the passed motion. • Puncturing is done across the overall rate-1/2 BCC encoder output continuously. – Puncturing for arbitrary SIGB length can work with one portion of padding bits.

(Marvell) Slide 14 doc.: IEEE 802.11-16/0037r1 Conclusions • Continuously puncturing the rate-1/2 encoded bits of each field is proposed • Very efficient, flexible, and simple solution to support arbitrary length of HE-SIGB fields • Effectively the HESIGB bits can be passed through a continuous BCC encoder. Submission Slide 15 Yakun Sun, et. al. (Marvell) doc.: IEEE 802.11-16/0037r1 SP • Do you support to add the following to the current SFD: – SIGB bits for each SIGB content channel are continuously encoded with 1 BCC encoder?
