partition indication. The BS asks the MS to send wideband CQI and spatial rate for the second frequency partition using long term feedback: Ob00: Frequency partition index 0; 0b01: Frequency partition index 1; Ob10: Frequency partition index 2; Ob11: Frequency partition index 3; BS sets long-term FPi to a different value than FPj and FPSlong term FPI > 0. Codebook Mode Codebook Feedback Mode and Codebook Coordination: ObOO: Base mode with codebook coordination disabled; 0b01: Transformation mode with codebook coordination disabled; Ob10: Differential mode with codebook coordination disabled; Ob11: Base mode with codebook coordination enabled. Codebook Subset ObO: report PMI of the base codebook or transformed base codebook; Ob1: report PMI of the codebook subset or transformed codebook subset. Codebook_Mode Codebook Feedback Mode and Codebook Coordination: 0b01: transformation mode with codebook coordination disabled; Ob10: differential mode with codebook coordination disabled; Ob11: base mode with codebook coordination enabled. Codebook_Subset Ob0: report PMI from the base codebook or transformed base codebook; Ob1: report PMI from the codebook subset or transformed codebook subset. Codebook_ Codebook Feedback Mode and Codebook Coordination: Coordination ObO: base mode with codebook coordination disabled; Ob1: base mode with codebook coordination enabled. Codebook_Subset ObO: report PMI from the base codebook; Ob1: report PMI from the codebook subset. Measurement Ob0: Use the midamble for CQI measurements; Method Indication Ob1: Use pilots in open-loop region with Ns streams for CQI measurements. 10.2 Downlink control channels Table 10-8 UL Sounding Command A-MAP IE Parameters [2] Parameter Size (Bits) Description A-MAP IE type UL Sounding Command A-MAP IE Sounding Subframe Indentifies the sounding subframe.
