Idle Mode reselection strategy:
•
•
•
•
•
L<->L: Intra-Freq, Inter-Freq reselection
L->U: coverage based reselection
LTE is preferred higher reselection priority than GSM and UMTS
With the same BW, U900 has lower priority than U2100 because it has wider coverage
GU->L: reselection based on priority (LTE has highest reselection priority, GSM has the lowest reselection priority)
UE prefer to stay in LTE when LTE coverage exists
•
•
Once UE detect LTE signal higher than reselection threshold, then reselect from GU to LTE
L1800 has highest priority with largest bandwidth (10MHz)
UE will reselect to UMTS/GSM if moves out of LTE coverage area
•
•
UE will start to detect (UMTS U2100 F1)/(GSM 900) signal when LTE serving RSRP drop to below none-intra-freq search
threshold, and trigger reselect to UMTS/GSM when LTE signal further drop to below reselection threshold and UMTS/GSM
signal higher than required threshold
UE will reselect to UMTS in areas that exist Huawei 3G coverage, and reselect to GSM if there is not 4G and 3G at the
same time

From 3GPP 25304, UE shall measure all inter-RAT layers with higher priority than serving cell, and reselect to the higher Srxlev cell on the highest priority layer.

Based on this, if more than one LTE higher priority layers are set in 3G for U to L reselection, UE shall measure all LTE layers regardless they are same or different priority, and reselect to
the highest layer with higher RSRP.

If UE doesn’t support L2100, then it will measure L1800 only then reselect to L18.

If UE support both L1800 and L2100, UE shall measure both layer.

DL 4x4 MIMO:
This feature configures four antenna ports for both eNodeBs and UEs for downlink transmission and adaptively selects transmit
diversity or spatial multiplexing for each UE to increase downlink throughput and improve coverage performance.
Compared with 2x2 MIMO and 4x2 MIMO, this feature doubles the downlink peak rate, raises downlink throughput, improves
coverage performance, and provides better user experience.
DL 4x2 MIMO:
This feature configures four antenna ports for downlink transmission and adaptively selects transmit diversity or spatial
multiplexing for each UE to increase downlink throughput and improve coverage performance.
4x2 MIMO differs from 2x2 MIMO in the following aspects:
• Transmits additional reference signals over antenna ports 2 and 3.
• Performs frequency switched transmit diversity (FSTD) in addition to space frequency block coding (SFBC).
• Uses a separate codebook that contains 16 precoding matrixes for closed-loop MIMO.

TAC-LAC Mapping
Principle
In LTE, the core network paging is based on the TAL,2G/3G is based on
LAC. TAL and LAC paging features roughly, So the use of TAL and LAC
mapping. Currently, the core network product specifications are as follows:
•
A core network can plan any number of TAL, 1 TAL can accommodate
16 TAC.
•
1 TAC can accommodate 30~100 eNodeB.
•
Taking into account the amount of signaling, paging performance and
the need for future expansion, this limit is not in accordance with product
specifications configuration.

Appendix – RS Power Configuration
RS power distribution
One RB include 12 Subcarriers and 7 symbol, Time slot is 0.5ms.
a). For the symbol with RS , there are 2*RS element, 2*Null element, 8
normal resource element.
b). For the symbol without RS, there are 12 normal resource element
What’s meaning of PAPB?
PA,PB indicates power distribution between RS
element and normal RE
Power of RE=(PA)*(PB)*RS power
Notice: Configuration of M2000 for PA, PB is GUL value,
here I use (PA)&(PB) to represent physical value.
Appendix – RS Power Configuration
Symbols will be sent out for moment by moment, and we suppose network bandwidth is 20Mhz with 100 RBs.
So, if we configure PA,PB as (-3,1) and set RS power is 18.2dBm(0.066W)
a). For the symbol with RS, total power for one RB is
Tot=2*RS+8*RE=2RS+8*(PA)*(PB)*RS
As per relevant definition in 3GPP protocol, (PA)=1/2, (PB)=1, so
Tot=2RS+8*1/2*1*RS=6*RS
Now we have 100 RBs, so total power for whole bandwidth is
100*6*RS=100*6*0.066W≈40W
b). For the symbol without RS, total power for whole bandwidth is
Tot=100*12*RE=100*12*(PA)*(PB)*RS=100*6*RS≈40W
