G.5.1 General

Annex G.5 is applicable for clauses 9.3, 9.4, 9.5 and 9.7. Common to those clauses is, that a throughput ratio γ of the form is measured. These clauses are tested exclusively with “slow” multipath fading profiles. Hence the test time is governed by test time due to fading, and number of samples due to statistical significance is not applicable.

The test requirement in clause 9.4 is a ratio of 2 throughput tests γ. In either numerator or denominator (depending on test case) a target throughput is desired, which is established by an approach resulting in the throughput and the reference SNR. This SNR is then reused when measuring the throughput of the other factor of the formula. The formulas for calculation of γ are defined directly under sections 9.4.

The test requirements in clauses 9.3 and 9.5 are a ratio of 2 throughput tests γ. , where numerator and denominator are ordinary throughput tests. The formulas for calculation of γ are defined in sections 9.3 and 9.5 respectively

G.5.2 Establishing SNR

Adjust SNR such that the measured throughput is within 2% of target value (60, 70 or 90% depending on test case). The approach, leading to target throughput and reference SNR is not specified.

The resulting SNR is the reference SNR to use when measuring throughput in the other factor (numerator or denominator) of γ.

To achieve statistical significance the final throughput measurement must be done with MNS samples, given table G.5.4-1

G.5.3 Measuring T-put

To achieve statistical significance the final throughput measurement must be done with MNS samples, given in table.G.5.4 -1. Number of samples due to statistical significance is not applicable.

For measuring t_subband, t_wideband, t_reported and t_fix, the SS collects ACK, NACK and statDTX from the UE and records the time, elapsed from the beginning of the test. The payload size, received by the UE and acknowledged towards the SS, may vary within a test versus time (e.g. due to subband changes upon a UE report) Throughput is calculated in the SS by summing up the payload, associated to each ACK, from the start of the test and dividing the accumulated payload in kilobits by the time in seconds, elapsed from the beginning of the test. This is similar but not same as in G.2.2. (Main difference in bullet d, where the payload size is constant).

For measuring t_median, t_ue, t_rnd, t_{ue,follow1,follow2} and t_ue,rnd1,rnd2, the SS collects ACK, NACK and statDTX from the UE and records the time, elapsed from the beginning of the test. The payload size, received by the UE and acknowledged towards the SS, is constant. Throughput can be calculated in the SS by multiplying the payload size with the number of ACKs and dividing the accumulated payload in kilobits by the time in seconds, elapsed from the beginning of the test, being associated to the following ratio: ACK/ (ACK+NACK + DTX).

G.5.4 Number of samples for throughput ratios

TT for γ and MNS are based on theoretical estimations.
