The average throughput for a single HSDPA user can be expressed as a function of the average HSDSCH SINR, given the maximum number of HSPDSCHs. Since C is the transmission power of the HSPDSCH ( PHSPDSCH_tx) divided by the path loss (Lp), the key factor to define the value of the SINR and throughput is the received interference: I =Iown(1-a)other where the interference is defined by three factors: in the first place, the interference received from the own cell (lown), which depends on the multipath propagation in the cell, typically named the orthogonally factor (a); in the second place, the interference from other cells (lother); and finally the noise power from the thermal source and equipment (PN). Additionally, the 'G factor' can also be defined as a function of the interference in the cell: Combining these definitions, the SINR can be expressed by the following formula: However, since the total HSDPA power is shared between the HSPDSCH and the HSSCCH, the SINR can be expressed as a function of the maximum HSDPA power in the cell: Max HSDPA - PHSSCCH_tx For a given maximum transmission power, the SINR can be obtained by applying the 'G factor' given to the cell configuration (i.e. -5 in the 3GPP macrocellular configuration) and obtaining the value of HSDPA Pedestrian Vehicular Average G-factor [dB] Figure B.8 HSSCCH power versus G the factor HSSCCH power from simulated distribution tables, as shown in Figure B.8. Finally, the throughput can be obtained from throughput versus SINR tables also obtained by simulation. Node B Configuration The Node B configuration should be configured to enable it to carry the air interface capacity for DCH and HSDPA traffic. One Node- B will typically serve three base stations or sectors. lub Configuration/Sizing The lub configuration should be calculated based on the node B configuration, and is an estimation of the average number of simultaneous users for each of the sectors. The HSDPA throughput also needs to be taken into account. This dimensioning will be a trade-off betwee
