Flexi Lite BTS A BTS type called Flexi Lite BTS has been available in RU40 On Top. Flexi Lite BTS is a new, small-sized WCDMA BTS that can be used in various indoor and outdoor installation options (such as floor, wall, stand, pole, mast, lamp and other street furniture). Flexi Lite BTS is extremely compact BTS that consists of baseband processing unit, RF module unit, integrated antenna (for optional use) and Ethernet ports included in one small box:
RF module unit provides the Radio Frequency (RF) functionality. RF module unit provides up to 10W + 10W output power supporting MIMO (up to two MIMO cells per BTS). Maximum of two carriers (two cells per carrier) can be configured with Flexi Lite BTS. With one sector (omni) configuration Flexi Lite BTS supports 2-way Rx Div while if two sectors are configured, then 1-way Rx Div is supported. Baseband processing unit baseband processing as well as control and transmission functionality. Optional integrated antenna with gain > 6dBi. If needed external antenna can be used. Ethernet ports providing IP transport.

Flexi Lite BTS capacity Flexi Lite BTS provides up to 4 cell capacity with two sectors or up to 2 cells with single carrier. The output power option of max 10W + 10W per BTS is available. Flexi Lite BTS consists of HW Rel.3 baseband unit providing capacity of 2,5 subunits.
F i g u r e 2 Flexi Lite BTS subunits capacity
2.1.1
Flexi Lite BTS system baseband capacity details Flexi Lite BTS baseband unit consists of subunits that can be used for the following:
CCCH processing;
R99 users processing;
HSDPA users, and throughput processing;
HSUPA users and throughput processing;
CS Voice over HSPA users processing;
Interference cancellation processing.
Note that Flexi Lite BTS contains baseband resources for Common Control Channels processing for 4 cells/15 km cell range, 3 cells/20km cell range or 2 cells/30km configurations included in BTS capacity. However from practical side (indoor/outdoor micro cell environment) lower cell ranges are expected (for example: 100/300/500 meters). One Rel.3 subunit provides capacity of 96 Rel99 CE. The maximum available baseband capacity of Flexi Lite BTS for pure traffic depends on:
Local Cell Group (LCG) configuration type; Activated Interference Cancellation unit (PIC pool); HSUPA static resources (optional static reservation for HSUPA data/voice users) HS_Cell_FACH static resources (optional static reservation for HS-FACH UL users)
Local Cell Grouping functionality allows splitting available BTS baseband capacity into baseband pools responsible for processing traffic from dedicated group of cells. Local Cells Grouping functionality is frequently used for Flexi Multiradio BTS to create

dedicated baseband resources for group of cells. Flexi Lite BTS supports in maximum four cells and therefore only one LCG can be created.
There are two LCG configuration types available for Flexi Lite BTS which describes BTS HSPA traffic processing capability. The two LCG configuration types are as follow:
Rel.99 only configuration
Small HSPA configuration
The LCG configuration type is set during BTS commissioning using HSPA setting parameter. If not commissioned then Small HSPA configuration is assumed by default.

Flexi Lite BTS LCG configuration types
Small HSPA configuration activates HSDPA scheduler and allocates 0,625 subunits for scheduler purpose.

2.2.
Common Control Channels The following DL Common Control Channels are supported per each cell in BTS:
1 x P-SCH (Primary – Synchronization Channel);
1 x S-SCH (Secondary – Synchronization Channel);
1 x P-CCPCH (Primary – Common Control Physical Channel);
1 x P-CPICH (Primary – Common Pilot Channel);
1 x PICH (Paging Indicator Channel);
1 x AICH (Acquisition Indicator Channel);
3 x S-SCCPCH (Secondary Common Control Physical Channel).
In the UL, the resources for processing the PRACH channel per each cell are required. In this document, it is assumed that Flexi Lite BTS cell range is not higher than 15km. For such cell range even with 4 cells, Flexi Lite BTS does not require any additional baseband resources for CCCH processing. However, if from some reasons higher cell range is needed (for example, more than 15km with 4 cells or more than 30km with 2 cells) additional baseband resources and CCCH license key might be needed. For such situation, see RU40 Baseband Dimensioning: Flexi Multiradio BTS Guideline , CCCH dimensioning rules for Flexi System Module Rel.3 (FSMF) BTS.
2.2.1
Capacity licenses The Flexi Multiradio WCDMA BTS and Flexi Lite BTS licensed capacity defines the capacity that the operator has purchased. The licensed capacity can be less than the maximum hardware capacity. Flexi WCDMA BTS Baseband capacities are allocated according to the capacity license file. Because the BTS exists in high volumes in the network, Nokia Siemens Networks does not generate licenses for these network elements directly (NE licenses), but a socalled pool licenses are used. This means that the user gets the license to use a dedicated amount of features or capacity (pool license) and it is up to the user to determine how these NE licenses are distributed towards the network elements.
There are four types of capacity licenses, namely: -
-

Rel99 CE license defines the maximum capacity for pure Rel99 traffic. HSDPA/HSUPA schedulers are not consuming Rel99 CE licenses. The HSDPA BTS processing set describes the maximum HSDPA that allows reaching a certain number of HSDPA users and DL throughput. Note that the HSDPA BTS processing set does not directly increase the capacity for maximum user amount and throughput. Separate ASW (application software) licenses for peak throughput and user amount are required. HSDPA BTS processing set capacities are as stated below:
HSDPA BTS processing set 1: 32 users and 7.2Mbps;
HSDPA BTS processing set 2: 72 users and 21Mbps;
HSDPA BTS processing set 3: 72 users and 84Mbps.
Multi RAB UE having more than one HSDPA RAB is counted as one user from HSDPA Processing Set license point of view. For example, 32 Multi RAB UEs, each having two HSDPA RABs, consume one HSDPA Processing Set 1 license capacity. The HSUPA BTS processing set describes the maximum HSUPA that allows reaching a certain number of HSUPA users and UL throughput. HSUPA BTS processing set provides simultaneously throughput (5.8Mbps) and user amount (24 HSUPA data/CS voice over HSPA users). With x number of available HSUPA licenses, the HSUPA baseband reservation is able to fulfill the simultaneous x * 5.8Mbps and x * 24 users requirement. 1,75 subunits is the maximum that can be used for HSUPA. Multi RAB UE having more than one HSUPA RAB is counted as one user from HSUPA Processing Set license point of view. For example, 24 Multi RAB UEs, each having two HSUPA RABs, consume one HSUPA Processing Set license. For commissioning purposes, all licenses (including Rel99 CE licenses) are activated for a 14-day period. For more specific information, see Licenses Management in WCDMA RAN.
NOTE: License files available at BTS are limited with commissioned licenses. For example, if 100 R99CE license file is available at BTS, while commissioned numberOfR99ChannelElements is set to 90, then BTS shall only use 90 R99 CE licenses.
2.3.
Dedicated Channels For baseband dimensioning purposes, a certain number of Rel99 CE per each active DCH user is required. Baseband resources are required per each DCH active user in “no handover” state and per each DCH user in “soft handover” state. Additional baseband resources are not required either for users in softer handover state or compressed mode.

For multi RAB cases, Rel99 CE requirements need to be calculated as a sum of Rel99 CE requirements for single bearers used in multi RAB call. The number of Rel99 CE depends on RB type and minimum SF. Table 11 and 12 present required number of Rel99 CE per each active connection for basic set of RABs.

Table 2 Baseband resources required per one Rel99 traffic channel
2.3.1
Asymmetric UL/DL Rel99 CE allocation Asymmetric UL/DL allocation means that the UL and DL directions have different bit rate requirements. The rule for allocating Submodule resources for asymmetric bit rates is based on a higher data rate requirement, but Rel99 CE reservations are done separately

for UL/DL. For example, if the UL bearer is 64 kbps and the DL bearer 384 kbps, the CE reservation is 4 CE in UL and 8CE in DL. UL and DL resources have to be allocated inside one submodule but there is no direct connection between UL and DL resource allocation. In other words, UL and DL resources do not have to be allocated symmetrically across submodule/subunit UL and DL capacity (see Figure 12).

HSDPA and BTS dimensioning Some supported capacities mentioned in this document may require separate licenses in the RAN before they can be activated. For more information, see Licenses Management in WCDMA RAN document. For more specific information related to HSDPA, see HSDPA in BTS document
3.1
HSDPA scheduler There is one type of HSDPA scheduler available with Flexi Lite BTS which is activated when Small HSPA configuration has been commissioned. Note that when LCG configuration type has not been commissioned at all, then by default Small HSPA configuration is assumed. The HSDPA scheduler supports 64QAM, MIMO, and DC-HSDPA features serving up to 180 HSDPA users from one to four cells. With DC-HSDPA feature and four cells, the maximum downlink HSDPA throughput is 84Mbps. After scheduler activation there is no need to allocate any additional baseband resources to reach 84Mbps. The scheduler provides HSDPA throughput, which depends on activated features, number and type of HSDPA BTS processing sets, and HSDPA throughput commissioning by the operator. The operator can specify the maximum throughput for HSDPA scheduler. The maximum throughput for the scheduler is commissioned in steps called HSDPA throughput steps (HSDPA Throughput Step) . Operator can select HSDPA throughput step values from 1 up to 35. The HSDPA throughput step can be used to limit HSDPA scheduler throughput. Each HSDPA throughput step corresponds to 7.2Mbps
For example: Small HSPA configuration (1 HSDPA schedulers) Commissioned HSDPA throughput step of HSDPA scheduler equal to 2 HSDPA_scheduler #1_throughput = 2 * 7.2Mbps = 14.4Mbps;
The table below presents the capability of single HSDPA scheduler.

3.2
Tcell grouping with Flexi Lite BTS Tcell grouping is used to group cells to the HSDPA scheduler. Tcell groups 1 and 3 are handled by the Flexi Lite BTS scheduler. The same Tcell values can be used by different cells if those are allocated to different frequency layers. With Dual Cell (DC) HSDPA feature cells from one sector should have the same Tcell value. . The principles of grouping (maximum four Tcell groups per LCG are possible) are as follows:
3.3
Group 1: Tcell values 0, 1 and 2;
Group 3: Tcell values 6, 7 and 8;
HSDPA BTS Processing Set HSDPA scheduler requires HSDPA license so called HSDPA BTS processing set providing user and throughput capacity. To learn more about HSDPA BTS processing sets, see chapter 2.2.1. Since only one HSDPA scheduler can be activated all licensed capacity is directly dedicated to the scheduler.
3.4
Associated UL/DL DCH The associated UL/DL DCH of the HSDPA user requires the capacity in the same way as a normal DCH. See table below.

HSUPA and BTS dimensioning Some supported capacities mentioned in this document may require separate licenses in the RAN before they can be activated. For more information, see Licenses Management in WCDMA RAN document. For more specific information related to HSUPA, see HSUPA in BTS document Baseband capacity is reserved for HSUPA on a need basis. The baseband capacity allocation may be changed dynamically between DCH and HSUPA use. In the baseband allocation, DCH has a higher priority than HSUPA. The operator may commission a minimum fixed reservation for HSUPA, but the rest of the capacity is dynamically allocated to HSUPA when DCH does not need it. The minimum HSUPA baseband allocation is 0 subunits. In this case, only HSUPA MAC-e is active. At least one HSUPA BTS processing set and HSDPA BTS processing set license is required (HSUPA user consumes one user capacity from both HSUPA BTS Processing Set and HSDPA BTS Processing Set license). HSUPA is supported only with the co-existence of HSDPA. To activate HSPA, Small HSPA configuration needs to be commissioned. The HSUPA scheduler supports up to 140 HSUPA users from one to four cells.
4.1
HSUPA resource steps HSUPA baseband resource allocation is done with specific sizes of resource steps. The amount of required resources depends on the desired throughput and the number of data HSUPA users. HSUPA scheduler allocates available baseband resources according to available HSUPA license and traffic conditions. Baseband resources allocated for HSUPA purpose can change dynamically, based on current need (number of active users and combined L1 throughput of all data HSUPA users). HSUPA baseband resource allocation is performed on a step basis. One HSUPA baseband resource is called a HSUPA resource step. One HSUPA resource step consumes 0.125 subunit.

Figure 5
HSUPA resource steps
HSUPA activation does not require fixed processing resources when the feature is being activated. At least one HSUPA BTS processing set and HSDPA BTS processing set license is required (note that HSUPA user consumes one user capacity from both HSUPA BTS Processing Set and HSDPA BTS Processing Set license).
4.2
HSUPA resource allocation HSUPA does not consume Rel99 CE licenses (even for SRB purpose). The maximum baseband resources that can be allocated for HSUPA scheduler, depends on amount of available HSUPA BTS processing sets. If the total number of available Rel99 CE licenses and the number of HSUPA resources (described by the number of available HSUPA BTS processing sets) exceed BTS capacity for traffic use, the overlapping baseband capacity can be dynamically exchanged between R99 and HSUPA users. To allocate the next HSUPA resource step, an additional free capacity of 6 Rel99 CE is needed. The required 6 Rel99 CE free on top of the HSUPA resource step is to avoid a “ping-pong” effect in reserving and freeing HSUPA resource steps. This is needed so that the HSUPA resource step is not requested to be back immediately after its allocation. When free channel capacity drops below four CE, the Resource Manager starts to free resources used by HSUPA.

Exemplary license overlapping scenario
One HSUPA BTS Processing Set per BTS (called hybrid HSUPA Processing Set ) provides capacity of 48 Rel99 CE that can be used when all Rel99 CE licenses have been consumed. Each utilized Rel99 CE, decreases amount of HSUPA users allowed by hybrid HSUPA Processing Set according to formula below:
Amount_of_allowed_HSUPA_users_by_hybrid_HSUPA_Processing_Set Roundup (Amount_of_allocated_Rel99_CE / 2)
=
24
–
Equation 1 Amount of allowed by hybrid HSUPA Processing Set HSUPA users Where: Amount_of_allowed_HSUPA_users_by_hybrid_HSUPA_Processing_Set – amount of HSUPA users allowed by hybrid HSUPA BTS Processing Set license Amount_of_allocated_Rel99_CE – amount of Rel.99 CE allocated for R99 users from hybrid HSUPA Processing Set license capacity.
For example: 1 HSUPA BTS Processing Set license available 30 Rel99 CE licenses available 35 AMR 12.2 users exists in the BTS
30 AMR users consumes 30 Rel99 CE licenses while remaining 5 users consumes Rel99 CE capacity (5 Rel99 CE) from hybrid HSUPA Processing Set license
Amount_of_allowed_HSUPA_users_by_hybrid_HSUPA_Processing_Set = 24 – Roundup (Amount_of_allocated_Rel99_CE / 2) = 24 – Roundup (5 /2) = 24 – Roundup (2.5) = 24 – 3 = 21
21 HSUPA users are still allowed by hybrid HSUPA Processing Set license

Dimensioning WCDMA RAN: Flexi BTS Baseband
When R99 users consume hybrid HSUPA license capacity also HSUPA throughput might be affected since less HSUPA resource step(s) are available for HSUPA scheduler. Hybrid HSUPA Processing Set license corresponds to 8 hybrid HSUPA resource steps. Each 6 Rel99 CE decrease amount of hybrid HSUPA resource steps available for HSUPA scheduler according to formula below:
Amount_of_hybrid_HSUPA_resource_steps_for_HSUPA_purpose = 8 – Roundup(Amount_of_allocated_Rel99_CE / 6)
Where: Amount_of_hybrid_HSUPA_resource_steps_for_HSUPA_purpose – amount of hybrid HSUPA resource steps available for HSUPA scheduler allocation. Amount_of_allocated_Rel99_CE – amount of Rel.99 CE allocated for R99 users from hybrid HSUPA Processing Set license capacity.
When baseband capacity is covered by hybrid HSUPA Processing Set license and Rel99 CE licenses (license overlapping), formulas above take into consideration only not overlapped Rel99 CE (allocated Rel.99 CE available with hybrid HSUPA Processing Set license capacity). For example: One HSUPA BTS Processing Set available (8 hybrid HSUPA resource steps) 108 Rel.99 CE licenses available 2 hybrid HSUPA resource steps overlapped with Rel99 CE licenses
In total R99 traffic might consume 108 Rel99 CE (108 Rel.99 CE licenses) + 48 Rel.99 CE available with hybrid HSUPA Processing Set license.
120 AMR 12.2 users are in the BTS, which means that 120 Rel.99 CE are consumed (108 Rel99 CE licenses + 8 Rel99 CE from hybrid HSUPA Processing Set license)
Amount_of_allowed_HSUPA_users_by_hybrid_HSUPA_Processing_Set = 24 – Roundup (Amount_of_allocated_Rel99_CE / 2) = 24 – Roundup (8 / 2) = 24 – Roundup (4) = 24 – 4 = 20
Amount_of_hybrid_HSUPA_resource_steps_for_HSUPA_purpose = 8 – Roundup(8 / 4) = 8 – 2 = 6
After allocation of 8 Rel99 CE, hybrid HSUPA Processing Set license has capacity of 20 HSUPA users and 6 HSUPA resource steps.

HSUPA resource commissioning is performed with two parameters - HSUPA BB decoding capacity Mbps and HSUPA BB minimum users . Up to two HSUPA resource steps can be statically commissioned for HSUPA (see chapter 4.3). Note that hybrid HSUPA Processing Set is always dynamic and cannot be statically reserved.
