Scenarios, Enhancing Operator's Brand Value and Offering Differentiated Solutions
Background & Pain Points


With the rapid expansion of high-speed railway in China,
the service experience of high-end high-speed railway
users increasingly affects operators' brand value.
The LTE network capacity gradually becomes incapable of
meeting the concentrated service demands of high-speed
railway users.

Base Station–Level Power Saving: Symbol Power Saving/Timing Carrier
Shutdown/Air Interface Power Saving
Power Saving Functions
•
Symbol power saving: When the base station
detects that no data is carried on symbols, it shuts
down the RF components of the RRU/AAU in real time
to reduce system energy consumption. When the base
station detects that data is carried on symbols, it starts
the RF components of the RRU/AAU in real time to
ensure the data transmission integrity.
• Timing carrier shutdown: This function blocks cells
and keeps the RF modules in the carrier shutdown
state in no-service periods to save energy.
• Air interface power saving: This function increases
the number of no-data-transmission time windows,
during which symbol power saving can take effect, to
save energy. To spare more time windows, the base
station prolongs the interval of sending messages over
common channels and converges service data into the
timeslots corresponding to common channel messages
for transmission.
3.3 Converging the symbols used for
sending messages over common channels

UE Power Saving: Power Saving Using BWP Configuration
Background and
Purpose

When a UE is performing low-rate services with small
packets, the UE can work on the BWP2 with small
bandwidth to save power.
UE Capability

Key Principles
If a UE supports bwp-SameNumerology, the UE supports
power saving using BWPs. Chipsets provided by HiSilicon,
Qualcomm, Intel, MTK, and Samsung support BWPs.
A UE is configured
with two dedicated
BWPs: one full-band
BWP1 and one
narrowband BWP2.
Benefits and Impact


Benefit: The power consumption of the communications
module decreases by 10–15%.
Impact: After this function is enabled, the throughput of the
UE may decrease, the delay may increase, and the cell
throughput may decrease because the UE works on a
power saving bandwidth.
