Abstract

In an 802.11az wireless system, a first station device transmits an NDP PPDU data unit in accordance with a range measurement packet exchange by constructing the NDP PPDU data unit to include an uplink (UL) length field element or a legacy signal length (LLEN) field element derived from a specified number of symbols (N) and number of repetitions (N) for the NDP PPDU data unit, and then sending the NDP PPDU data unit to a second STA device, where the values of the UL-length and LLEN field elements are computed as UL-Length=LLEN=10+y+6*Σ((N(i)+1)*N(i)), where y=0 for NTB I2R/R2I NDP and TB R2I NDP PPDUs, and where y=3 for TB-I2R NDP PPDUs.
