ed Advanced Antenna System (AAS) Beam Select messages may be sent by the MS. Use CQICH Indicator Flag Always The N MSB values of this field represent the N-bit payload value on the fast-feedback channel reserved as indication flag for MS to initiate feedback on the feedback header, where N is the number of payload bits used for S/N measurement feedback on the fast- feedback channel. MS-Specific Up Power Offset MS-specific and not always Unsigned value in units of 0.01 dB. Adjustment Step present MS-Specific Down Power Offset MS-specific and not always Unsigned value in units of 0.01 dB. Adjustment Step present (Continued) Table 9-13 Content of a UCD MAC Management Message [1] Continued Information Field in UCD Message Usage Description Minimum Level of Power Offset Always Signed value in units of 0.1 dB. Adjustment Maximum Level of Power Offset Always Signed value in units of 0.1 dB. Adjustment Handover Ranging Codes Always Number of handover ranging CDMA codes. Possible values are 0-255. Initial Ranging Interval Always Number of frames between initial ranging interval allocation. Transmit Power Report Always Normalized C/N for Channel Always Signed integer for the required C/N (dB) for Channel Sounding Sounding which overrides C/N for the channel sounding. Initial_Ranging_Back-off_Start Always Initial back-off window size for initial ranging contention expressed as a power of 2. Initial_Ranging_Back-off_End Always Final back-off window size for initial ranging contention expressed as a power of 2. Bandwidth_Request_Back-off_Start Always Initial back-off window size for contention-based bandwidth request expressed as a power of 2. Bandwidth_Request_Back-off_End Always Final back-off window size for contention-based bandwidth request expressed as a power of 2. Uplink_Burst_Profile for Multiple FEC When multiple FEC types are It defines the format of the Uplink Burst Profile parameter, which is Types used in the UCD message. The UL burst profile is encoded with a type of 1, an 8-bit length, and a 4-bit UIUC. The UI
