MTSI profile #6 [19] extended to 8000 frames |
|
NOTE1: MTSI profile #5 is not included because it assumes frame bundling, which may not be supported by test equipments. NOTE2: MTSI profiles have a length of 7500 frames; they have been extended to 8000 frames by appending the first 500 values at the end of the profile. |

Since the model simulates the packet transmission end-to-end, the delay profiles include a packet delay component that according to the definition of the UE delay in 3GPP TS 26.131 [1] is not attributed to the UE delay. This delay shall be included in the test equipment delay when deriving the UE delay from the delay measurments based on the cross-correlation of the injected and measured signals. Values for the compensation attributed to the packet delay profiles are shown in Table F.2.
