UC field is associated with the UL burst profile and thresholds. The UIUC value is used in the UL-MAP message to specify the burst profile to be used for a specific UL burst. Fast Feedback Region Always It contains same fields as in the FAST FEEDBACK Allocation IE, as well as the number of subchannels, number of OFDM symbols, subchannel offset, OFDM symbol offset, etc. Note that up to two parameters may be used for FDD/H-FDD, to indicate two fast- feedback regions in two groups. HARQ ACK Region Always It contains the number of subchannels, number of OFDM symbols, subchannel offset, OFDM symbol offset, etc. Note that up to two parameters may be used for FDD/H-FDD. Ranging Region Always The value of the parameter consists of up to four concatenated sections (one section per ranging method), each describing dedicated ranging indicator, ranging method, number of subchannels, number of OFDM symbols, subchannel offset, OFDM symbol offset, etc. Sounding Region Always Five bytes per each sounding region, PAPR Reduction/Safety zone, number of subchannels, number of OFDM symbols, subchannel offset, OFDM symbol offset, etc. MS Transmit Power Limitation Level Always An unsigned 8-bit integer which specifies the maximum allowed MS transmit power whose values indicate power levels in 1 dB steps starting from 0 dBm. H-FDD Group Switch Delay FDD/H-FDD Mode The delay (in number of frames) of H-FDD Group Switching transition. If this parameter is not present, H-FDD Group Switching Delay is set to H-ARQ ACK Delay. For H-FDD, either H-FDD Group Switch Delay or H-ARQ ACK Delay should be included in the UCD. Frame offset Always The offset between the frame of the corresponding CQI channel and the current frame. The offset between the frame of the corresponding UL burst and the current frame. Country Code Always Country code according to List of Mobile Country or Geographical Area Code. Number of Power Control Command Always The value in the Power Control Bitmap is the change that MS applies to its transmit power by changing the offset
