CID# 16:
Comment (Annex D, D7.2.1a, Page 124, Line 12):
The same field name "Frequency Bands Supported" used twice for two different fields in Figure 55b and in Figure 55e. One is used for all PHY Type Descriptors and the other is used for each individual PHY Type Descriptor, the names should be slightly different.
Proposed Change:
Use different field names.
Recommend Resolution: Accept in principle. Proposed text changes as in following slide
Resolution:
As in following slide

4. Proposed replacement text
Change ‘Frequency Bands Supported’ to ‘Specific Frequency Bands’ in Figure 55e
The PHY Type Descriptor consists of 4 fields as shown in Figure 55e.
The PHY Type field is an unsigned integer whose value identifies a PHY Type defined in Table 4c.
All Frequency Bands is a 1-bit field which indicates whether the optional Specific Frequency Bands field is present. If set to 1the optional Specific Frequency Bands field is absent and the PHY Type is supported in all frequency bands declared as supported in the Frequency Bands Supported field of the SUN PHY Capabilities IE. If set to 0 the optional Specific Frequency Bands field is present and the PHY Type is only supported in the frequency bands declared in the Specific Frequency Bands field of this PHY Type Descriptor.
The PHY Modes Supported field is a bitmap indicating which PHY modes are supported for the PHY Type. The PHY modes for each possible PHY Type are defined in Table 4d, Table 4e, Table 4f, Table 4g, Table 4h, and Table 4i. A bit set to 1 at position n in the bitmap indicates that the PHY Mode in row n the table of PHY Modes corresponding to the PHY Type is supported, otherwise it is not supported.
The optional Specific Frequency Bands field is encoded in the same manner as the Frequency Bands Supported field of the SUN PHY Capabilities IE.
