measurement method › Findings and proposals

› Operators started to measure power consumption of Base Stations (BS)

– Comparing of RBSs from different vendors– Due to too many factors involved in the test setup, the comparison

was not satisfied

Background


was not satisfied

› A work item at ETSI for BS EE measurement method started at the end of 2008

› First version about the static measurement method, published 2009

› Second version about both static and dynamic BS EE, published 2011

› Base Station EE measurement method› Static measurement method

– Measuring power consumption under static loads

– Simple but not realistic

ETSI ES 202 706


– Could be used as reference

› Dynamic measurement method– Measuring Energy Efficiency under

dynamic loads– Reflect the reality of BS behavior and

hence being representative

DYNAMIC METHOD IS THE MOST REPRESENTATIVE

› Improving the dynamic measurement method

– Including radio effects such as fading

– Better use of UEs

New work item on ETSI ES 202 706


– Better use of UEs – Including multi standard base

stations– Approaching harmonization with

ATIS– And there is more …

Verification & Findings of

ETSI ES 202 706


ETSI ES 202 706 in Ericsson lab

› UDP model can be hard to verify due to the lack of acknowledge mode

› Logs at both ends need to be analyzed in order to get true throughput and also count the discarded packets

ETSI standard UDP findings


› Complicated tuning of the UE UDP data throughput to reach TPmaxUE

› A more realistic approach would be to use TCP› Sending fixed amount of data starting at the same time for

all UEs– Different UE groups will have different downloading time

› Real UEs have a normal distribution at the RX sensitivity which causes different throughput at same BS output power

› Difficult to attach a UE at the lowest signal strength,

ETSI standard UE signal strength


› UE group 1 to UE group 3 facing almost same throughput due to absence of radio fading and multipath and hence good signal quality. Only UE group 4 differs

› Suggestion is to insert radio fading and multipath radio effects � reflecting the reality aspect of radio propagation
