he macro layer is equal to 6 dB whilst the threshold for the micro layer is set to 20 dB. The noise rise results from the combination of interference coming from the micro and the macro cell layers. Micro and macro cell layers interact, i.e. micro cell interference affects the macro cell layer and vice versa. In the second option, we set the noise rise threshold to 6 dB for both the macro and the micro layer, but the micro cells are de-sensitized at 14 dB. 5.5.5.2 Downlink 5.5.5.2.1 Single Operator Loading As in the UL, the number of users in the downlink for the single operator case gets de- fined as N_DL_single. Then DL simulations occur in a way that a single operator net- work gets loaded SO that 95% of the users achieve an Eb/No of at least (target Eb/No -0.5 dB) (i.e. 95% of users are satisfied) and the supported number of users N_DL_single is then measured [5]. 5.5.5.2.2 Multi-Operator for Macro to Macro and Macro to Micro In the macro to macro multi-operator case, the networks get loaded SO that 95% of users are satisfied and the obtained number of users is defined as N_DL_multi. For a given value of ACIR, the measured N_DL_multi is obtained and compared to the N_DL_single obtained in the single operator case. The multi-operator case (macro to micro) follows similar reasoning to that of the UL case. 5.5.5.3 Simulation Output Finally, the expected outputs include: capacity figures (N_UL and N_DL), DL and UL capacity versus ACIR in the multi-operator case, as well as outage (non-satisfied users) distributions. 5.5.6 BTS Receiver Blocking and Simulation Assumptions The simulations are static Monte Carlo simulations using a methodology consistent with the ACIR approach described in the preceding sections. For our examples, we construct the simulations using two uncoordinated networks at different frequencies. The fre- quencies assume a separation by 10-15 MHz or more SO that the BS receiver selectivity will not limit the simulation, and SO that the UE spurious and noise performance will dominate over its adja
