2. Comment Resolution for UEP • Section 5.3.16 describes supported UEP Types • Section 8.17 includes the clear definition and details of functionality of 3 UEP Types • Section 12.2.2.4 includes UEP MCS for SC PHY and the supported UEP Types in each UEP MCS • Editorial modification in Section 12.2.2.4 • Remove Annex D1 due to duplication

3. Supported UEP Types in Section 5.3.16 • Add the following sentence in Section 5.3.16 • …as an option. This UEP has three different types as described in 8.17 and may be applied for three different PHY modes described in 5.5.1

4. Details of Three UEP Types in Section 8.17 • Line 10-15 in Section 8.17 - re-replaced the following sentences • UEP Type 1 protects an aggregated frame which consists of MSB subframes, LSB subframes or both MSB and LSB subframes by using the different FECs, as described in 12.2.2.4, in all PHY modes. • UEP Type 2 protects an aggregated frame which consists of MSB subframes , LSB subframes or both MSB and LSB subframes by using different MCSs, described in 12.2.2.4, in all PHY modes. In addition, UEP Type 2 only uses UEP Specific IE, defined in clause 7.4.24  in order for the originating DEV to inform the recipient DEV of the separating position of MSBs and LSBs. If necessary, UEP Type 2 can transmit announce command frame with UEP Specific IE to dynamically change the segregating position according to the channel status. • UEP Type 3 protects MSB and LSB in a subframe unequally in the PHY layer by either applying different coding rates to MSBs and LSBs or mapping MSBs and LSBs to a skewed constellation. Capability of supporting UEP by coding and/or by the skewed constellation is defined in 7.4.7. UEP by coding is described in 12.2.2.4, 12.3.1.1 and 12.4 for all three PHY modes. UEP by the skewed constellation is described in 12.2.2.4, 12.3.2.5 and 12.4.2.12 also for all three PHY mode.

5. UEP MCS in Section 12.2.2.4 • Table 109 in Section 12.2.2.4 is replaced as following that includes UEP MCS for SC PHY and the supported UEP Types in each UEP MCS Table 109. UEP MCS for SC PHY mode

6. Editorial Modification • Modified description in Section 12.2.2.4 (Page 77) • Replace the sentence in Line 28 “The MCS types, which are used for unequal error protection, are shown in Table 109” to “The UEP MCSs are shown in Table 109.” • Add the words in Line 40, “In UEP Type 3, when the transmitter chooses one of the UEP MCSs ….” • Revise Figure 196 (Page 78) • Change LDPC (576,228) to LDPC (672,336) • Change LDPC (576,432) to LDPC (672,504) • Change LDPC (576,504) to LDPC (672,588) • Remove Annex D1 due to duplication
