Channel Element Capacity for EUL
Smartphones Overview
The Channel Element Capacity for EUL Smartphones feature reduces the CE cost
for EUL 2 ms and increases the number of EUL 2 ms devices which can be
connected at the same time.
Access Type:
WCDMA
Feature Identity:
FAJ 121 1883
Value Package Name:
Channel Element Capacity
Value Package Identity:
FAJ 801 0325
Node Type:
RNC
DU Radio Node
Baseband Radio Node
Licensing:
License required.
Summary
This feature decreases the CE cost for 2 ms E-DCH RL to 2 CE at the initial setup,
and when the user is granted a single HARQ process.
The feature brings the following benefits:
— Reduced CE cost for EUL 2 ms.
— A higher number of EUL 2 ms devices to be connected simultaneously for a
given amount of available CE.
— Less CE consumption for the same number of EUL 2 ms devices.
— More room for higher bit rates and better end user experience.
