A summary of Uplink Eb/No requirements

IntroductionIn this section we present a summary of lab measurements of Node-b Uplink Eb/No requirements. The lab measurements were performed as part of project FR25001. The summary is presented for a range of bearer rates under various channel conditions. These values are intended for use in dimensioning and planning of UMTS networks as well as bid quotations when customers specifically ask for details of Node-b Eb/No requirements.

Assumptions and how to use the dataThe data summarised in this section should be used in a way that is compatible with the framework of the following assumptions:

- Each value quoted in this section is effectively the long term average of the Eb/No measurement of a dedicated channel.

- Receiver diversity is enabled.- Eb/No is measured per antenna and then averaged over the main and diversity

branches.- Outer loop power control BLER1 target is constant- Channel multipath profile has a fixed tap delay pattern (details below).- Eb/No calculation is according to the 3GPP standard document 25.141 [1].

User Channel ConditionsThe measurements were performed under six different channel conditions. The channel conditions are presented in the following table.

Table 1 Channel Conditions under which the lab measurements were performed

The Pedestrian A&B and Vehicular A&B channel profiles are defined by ETSI [2], and are reproduced in the following two tables.

Summary of Results:

The Eb/No values were extracted from measurement data for the following BLER targets: 0.1%, 1%, 3%, 5% and 10%. Linear Interpolation was used in most cases. Where the desired BLER target fell outside the range of measurements, an extrapolation using a second order best-fit curve was used. Linear regression was used in rare occasions when the measurements did not appear to follow a disciplined shape. The complete analysis can be accessed on [3]. All Values are in dB.
