System Interference Solution (3/4)Solution 3 : Automatically background noise updateDescriptionIf the RTWP is high in free hour, and customer cant find the root cause and solve interference after RTWP troubleshooting. For the cell with stable background noise, you could synchronize the real background noise through Automatically background noise update algorithm, which will improve HSUPA available load. Fixed setting : -106 by default Automatic update : deliver the value detected during the night to Node B

Pros & Cons Benefit: - Keep the background noise consistent with the real value of background noise.- HSUPA available scheduling load may be increase.

Disadvantage: - The background noise reference must be recorded without any user in the cell.

System Interference Solution(4/4)Solution 4 : HSUPA anti-interference scheduling (feature WRFD-020136)

Description:

On commercial networks some site experience strong and random external UL interference. The traditional HSUPA scheduling algorithm considers only the total RTWP of a cell => available load resources are reduced and the HSUPA throughput decrease.

With this feature, UEs HSUPA scheduling is performed based on the cell RTWP and traffic volume of HSUPA UEs in the cell.

If the traffic volume (HSUPA and R99 users) is lower than the predefined threshold, HSUPA scheduling can be performed even if the ROT of the cell increases to a very high value.

Pros & Cons

Benefit: Improve user throughput even though interference exist. Disadvantage: Real RTWP will increase, the KPI such as access, call drop may be degraded. If there is no interference, this feature is useless and has no impact on any KPIs.

Target Overload Solution (1/13)Solution 1 : CQI feedback period optimization

Description:The uplink feedback channel HS-DPCCH of HSDPA consume part of uplink load More and more HSDPA user online at the same time in the cell (> 20 users); HSDPA uplink feedback channel contribute a big part of RTWP load. It is recommended to optimize HSDPA CQI feedback period, to reduce impact on uplink.

Pros & Cons Benefit: The CQI period is postponed => the Load of HS-DPCCH decrease => the available load for HSUPA will increase. Disadvantage: if the CQI period is too long, it could not reflect the accurate channel quality on time and HSDPA throughput may be affected.

Target Overload Solution (2/13)Solution 2: Target ROT Optimization

Description:

HSUPA scheduling depends on UL load. You can optimize the value of target ROTThe Higher is the target load => the more load is available for HSUPA

The defaulted target load is 75%, we suggest to modify to 90%.

Pros & Cons

Benefit: HSUPA user number capacity and cell throughput will improve

Disadvantage: As the uplink load increase, the coverage will decrease. Call drop may degraded a the edge off the cell.

Target Overload Solution (3/13)Solution 3 : RACH access parameter optimization

Description:

RACH access preamble adopt open-loop power control When the coverage is bad or massive RRC access exist => UE TX power could increase quickly involving RTWP peaks. In order to control RTWP peaks, RACH access parameters could be optimized. (More effective for indoor massive user scenario)

Pros & Cons

Benefit: Reduce the sharp impact of preamble open-loop power control on uplink RTWP in initial RACH access. Cell mean RTWP should decrease. Disadvantage: the access delay may increase

Target Overload Solution (4/13)Solution 4 : HSUPA 10ms BLER optimization

Description:

The current target BLER value is benefit for HSUPA user with high throughput in good coverage.

If many users are online at the same time with low throughput => UE sends high power in order to transfer low throughput (bad power efficiency)

In that case target BLER optimization parameter from 1% to 10% is recommended which will the UE Tx power and the nb of TB retransmission

Pros & Cons

Benefit: The uplink power efficiency will improved, HSUPA user throughput will increase, or RTWP may be decrease, KPI such call drop may improve.

Disadvantage: The parameter optimization may have negative affect for the user with real high throughput.

Target Overload Solution (5/13)Solution 5 : HSPA state transfer

Description:

In CELL_DCH state, when there is no data transmission, UE still need to send dedicated channel DPCCH and HS_DPCCH => control channel load is high when many users are online, and generates a big part of ROT.

After enabling HSPA state transfer switch, user will move to CELL_FACH or CELL_PCH state when there is low date transmission

Pros & Cons

Benefit : some uplink load will be saved, control channel load and RTWP will decrease . Disadvantage : Time delay will and signaling could increase (cell reconfiguration), and the call drop may be degraded.

Target Overload Solution (6/13)Solution 6: HSUPA CAC user number

Description:

For current HSUPA PO configuration, HSUPA consume more load than R99

When there are many HSUPA users in a cell, HSUPA CAC user limitation could decrease uplink load (Nb of R99 users could increase)

Pros & Cons

Benefit: Uplink load may decrease, user throughput may be improved.

Disadvantage: If the value is too low, the cell HSDPA capacity may be reduces, leading to waste in HSUPA resources

Target Overload Solution (7/13)Solution 7 : 2ms/10ms TTI switch based on RTWP + HSUPA 2ms period retry

Description: HSUPA 2ms TTI provide better throughput but will easily involve RTWP peaks when data bursts appears, especially in dynamic CE active scenario.

HSUPA 2ms TTI require more TX power, so we suggest to open 2ms/10ms TTI switch based on RTWP.

If 2ms period retry switch is on, massive 2ms/10ms ping-pong switch may exist in case of RTWP peaks => close the 2ms retry switch

Pros & Cons Benefit: Uplink load may decrease. Disadvantage: Lower throughput with TTI 10ms when the user have real high throughput requirement.

This feature can deactivate the secondary carrier of a UE supporting DC-HSDPA when the traffic volume of DC-HSDPA is low.

Deactivation of DC-HSDPA avoid redundant UL power of DC-HSDPA UE so as to decrease UL interference and save power for UE.

Pros & Cons

Benefit: save UE TX power consumption, decrease uplink load, improve HSUPA throughput.

Disadvantage: the time delay could increase for cell edge HSDPA user at none DC status.

Pros & Cons

Benefit: CE congestion will decrease, more user can access the network.

Disadvantage: call drop rate may be degraded as signaling increase, the time delay will degrade for high data transmission requirement user.

CE Resource Limit Solution (6/6)Solution 6 : CE overbooking (WRFD-140212) Description:

After the dynamic CE resource management feature is enabled, the RNC generally ensures the GBR of HSUPA users and the resources required for data transmission.

When the penetration rate of 2 ms TTI users is high and the actual UL HSUPA service volume is not high. This admission causes a low NODEB CE usage (waste of resources)

This algorithm optimize the difference between admission credits reserved by RNC and actual CEs consumption reported by Node B, to allow more access users and improve the CE usage.

Pros & Cons

Benefit: Relieves CE congestion during UE access, Increases the number of admitted UEs and the number of UEs with a 2 ms TTI, Increases cell throughput when Uu resources are sufficient.

Disadvantage: None.

Application: Depend on feature WRFD-010638 Dynamic CE Resource Management.When CE Overbooking is enabled, it is recommended that : DRA_BASE_ADM_CE_BE_TTI_RECFG_SWITCH under DraSwitch be turned on.
