e., SINR distribution or geome- try), and to calculate the CDF corresponding to those values for each test environment. The CDF for the test environment(s) is used to find the respective 50th percentile of SINR values. A new link-level simulation in the uplink is run for the selected test environment(s) under either NLoS or LoS propagation conditions with the purpose of obtaining link-level data rate and the residual packet error rate as a function of SINR. The link-level simulation uses air interface configuration(s) supported by the NR while taking into consideration the HARQ retransmissions, channel estimation, and phase noise impairments. The link-level spectral efficiency values (link data rate normalized by channel bandwidth) obtained from the previous step are compared using the set of SINR values obtained earlier for selected test environments. The mobility requirement is satisfied, if the value of the spectral effi- ciency is larger than or equal to the corresponding threshold value and if the residual decoded packet error rate is less than 1%, for all selected test environments. For the selected test environment, it is sufficient if one of the spectral efficiency values (of either NLoS or LoS propagation model) satisfy the minimum requirement. A similar methodology can be used for the assessment of the mobility requirement in the downlink. Reliability: Reliability refers to the capability of transmitting certain amount of user traffic within a predetermined time duration with high probability of success. In other words, reli- ability is the success probability of transmitting a layer 2/3 packet within a permissible time, which is the time it takes to deliver the small payload from the source layer 2 SDU ingress point to the destination layer 2/3 SDU egress point under certain channel conditions. This metric was defined for the purpose of system evaluation in the URLLC usage scenario. The minimum requirement for the reliability is a success probability in the order of 10 for transmitting a layer 2 protoc
