Combining, Capacity and Coverage


Combining, Capacity and Coverage (1/3)

• RM 60W max/TRX object, min 1 TRX object or 3G carrier/pipe

• RRH 40W max/TRX object, min 1 TRX object or 3G carrier/pipe

• With IDD doubled nominally the TRX object power level.

High coverage

• RM 10W min/TRX object, max 6 TRXobjects or 3/4 3G carriers/pipe

• RRH 6.67W min/TRx object, max 6 TRX objects or 3/4 3G carriers/pipe

• 3x3G carriers fit in 850 and 900 band and for 1800 band 4 carriers fit into one RM pipe

High Capacity

• Use RMs or RRHs with IDD.

• If the BTS is not having remote islands, the frequencies consumption is high. Likely going for dual band within 2G (900 & 1800) and separately within 3G (900 & 2100).

• If remote islands are included the headcount of FR modules may be very high

High capacity & coverage simultaneously



• Use only RRHs Low capacity & coverage simultaneously

• RM & RRH DL gain is nominally 2…3dB at mobiles.

• The uplink gain is unavailable unless configured in the same time 4UD. IDD is easy to build with RRH as it has 2 antenna interfaces and antenna optimized configuration as HW support.

Combining IDD Feature

• Later than ME1 (EX3.1), used external summing device to further boost Tx output power. Performance gain is max 2.5 dB

Combining DPTRX Feature



• Here the cumulative Tx power level can in theory exceed the FR power budget , but it is restricted by cumulative means once an active connection is requested by BSC to increase DL power and it is approaching BCCH power level (that is 0 = max).

• This feature has following limitations: for RMs and RRHs, only for 2G in a pipe of RM/RRH, at least 3 TRX objects reside in one pipe. The intention is to get more power for weaker CS/PS connections and still retain fairly big capacity.

• The HW limits the summary power level to 60W RM/40W RRH on each timeslot, but in average the further and weaker mobiles can still be heard and in case of rare Tx compression the mobiles will suffer of worse DL quality, but still be heard.

Dynamic Power Sharing


Categories and Rules of Configuration Overview

• Main configuration rule is: – support for 36 TRXs of 2G carriers and that can be deployed to max 12

sectors having max 16 TRX objects.

– 2G has no configuration limitations with sharing.

– 3G cells count is max 3 and with 6 carriers in one RM when shared.

– Without sharing it is 9 for low bands and 12 for high bands.

– The limitation comes from frequency budget

• Currently in ME1 (EX3.1), RP3 topology does not support duplicated links, loops, star connections, redundancy, nor recovery


Categories and Rules of ConfigurationConfiguration categories

• These configurations are defined in Product definition and recommended for customers and are mandatory to be tested by NSN.

• Promoted for testing both extremes: min capacity config with max coverage and max capacity config resulted with min coverage.

• Principally the performance of these configurations is optimal

Mandatory (=M) configurations

• The configurations are supported but the performance of these configurations may not be optimal

Supported (=S) configurations

• Configuration is inefficient e.g. 3 RMs antenna optimized where each RM pipes belong to only one sector at a time.

• A chain of 2 or 3 FRs and the earlier in chain FR is undefined in SCF, but the later FR is defined in SCF.

Not supported (=NS) configurations

• Example extension FSM used in shared configuration in ME1

Invalid (=I) configurations


Categories and Rules of Configuration

No SW/system testing is done


Categories and Rules of ConfigurationModules, Cabling configuration Rules and exceptions (1/6)

I. 1UD, 2UD Rx configurations can be used with normal TRXs

II. 4UD configurations can only be used with IDD. IDD also accepts 2UD. 4UD is antenna optimized configuration when 2 or more TRXs configured to IDD, but other pipe carrying aux Tx and 2nd and 3rd Rx diversity does not have to be specified to have any operational capacity for any TRX object. The Tx aux is located in another pipe than Tx main. The frequency budget must now fit to the used pipes in IDD & 2UD or IDD & 4UD. In shared case, in antenna optimized configuration, the associated FRs needs to have same SM as radio master.

III. Unspecified configurations (not specified in this doc) may also be supported, but not tested. These configurations are discouraged and BTS SW may find broken / operation degraded alarms on them and the performance can be poorer than nominal performance and TRX test may not work.

IV. Any RP3-01 port of any module (RM, RRH, ESMx) can be used to interconnect to peer module (RM) when SCF file has such defined. 3G FSM is excluded from this rule. 3G BTS in RU20 supports only usage of ports1&2.

V. Only 1 pcs of RP3-01 links from ESMx are supported at a time to one RM in ME1 (EX3.1) release (not supported dependent capacity RP3-01 link to same RM).



VI. Any power connector of ESMx or FSM can be used to provide the power supply to FR module. In addition, the FR can also be power fed by external power supply (applies typically in remote island cases).

VII. No RF cables (including Co-Siting or cross-feeding RF cabling) can be autodetected. With RM and for external antenna connectors belonging to same sector, any of external antenna connectors can be used to feed out the Rx diversity signal with other BTS. The Rx diversity coming from other BTS must be fed into Rx diversity connector. Cross-feeding, once configured, is typically taken from neighbour RM, but can also be taken from the same RM. No active SW support possible except SCF’s custom Rx gain setting. Note that cross-feeding is visible in SCF file so that it is counted as additional antenna. If cross-fed between 2 RMs with antenna optimized configuration, still defined in SCf file 4 antennas.

VIII. RM and RRH can not be used simultaneously in same sector. Then RRH is ignored. However both IDD and normal TRX objects can be used in same sector.

IX. Any TRX object numbers can be allocated on any FR pipes except on FR on SM’s port4 that can only have TRX objects 1…18 allocated.

X. Maximum of two RM modules can be installed on one casing for pole or wall configurations.



XI. MOBSS or EDGE license (will be built looking like MOBSS) optimized configurations are based on having 2 artifically split sectors using the same Tx and Rx antennas. That can only be built with SCF configuration having more than 1 sector sharing the same antennas and it can be resolved when TRX objects belonging to 2 different sectors are mapped to same antennas.

XII. RP3 link modulo per each RP3 link shall be used as per which technology is present standalone or which technologies are shared as per following table:

Technology /bandwidth

Modulo

Consumed indexes/capacity

2G standalone 4 1 for 11 TRXs (to fit max 36 TRXs in one RP3-01)

3G standalone 16 2 indexes for 1 carrier

2G & 3G together 16 2 for 1 3G carrier, 1 for 2G 2 TRXs

LTE/20MHz 2 2 for LTE carrier

LTE/15MHz 8 6 for LTE carrier (made actually 3 x 5MHz)

LTE/10MHz 4 2 for LTE carrier, MIMO doubles capacity

LTE/5MHz 8 2 for LTE carrier, MIMO doubles capacity

LTE/3MHz 16 2 for LTE carrier

LTE/1.4MHz 32 2 for LTE carrier

LTE/10MHz & 2G 4 2 for LTE carrier, 1 for 11 TRXs



LTE/1.4MHz & 2G 32 2 for LTE carrier, 1 for 1 TRXs



XIII. ME1 (EX3.1) nor RU20 do not support 3G extension FSM in shared configurations.

XIV. ESMx, FSM, RM and RRH modules follow connector numbering notation from left to right, but for antenna connectors right to left [NOTE: When observed in front of the front panel]. Furthermore, the antennas have flat numbering (RM:1…6 and RRH:1…2) without distinguishing is the antenna dual duplexed Tx & Rx or Rx diversity only. For RM, the Rx diversity to other BTS is fed from ext Rx connector per pipe (this is co-siting, not cross-feeding).

XV. Asymmetrical configurations are supported without any limitations. They may also have different BC(C)H power levels. In 3G the asymmetric configurations (like 2+1+2) will be converted to next equal configuration (becomes 2+2+2) for internal 3G capacity allocations.

XVI. FSM towards ESMx sync cabling shall be taken from RP3 ext1 connector of FSM.

XVII.When 2G TRX objects are defined, the first/only defined object number must reside within range 1…18. If specified TRX object number(s) 19…36 and ESMB (with 18 TRX objects capacity only) exists, those TRX objects will never become functional.



XVIII.2G dedicated or shared configuration will be terminated for 2G at each FR’s MAIA ASIC based on sector to antenna(s) mapping configuration (retrievable from SCF and BTS_CONF_DATA).

XIX. Synchronization master SM defines the Air interface timing and respective FCB shall feed to its dedicated and shared FRs. Synchronization slave SM indirectly forwards the FCB received from synchronization master to its dedicated FRs. Ethernet link follows the FCB.

XX. Sync master SM – sync slave SM RP3-01 connection must have minimized and always known length due to minimize extra timing compensation to shared FRs. Therefore FSFO Flexi System Fibre HF 2M 471851A cable shall only be used.

XXI. ESMx and flexi multiradio BTS is always incompliant with 3G HW release 1. FR and FSM HW release V2.1 or newer must however be compliant with FR HW release 2.



XXII.Max supported 72 antennas: with 6 sectors 6 antennas each, with 12 sectors 3 antennas each. Tested with 36 antennas. Note: not tested 9 sectors where each sector is having 4 antennas.

XXIII.One sector having some pipes normal and some other pipes antenna optimized is untested.

XXIV.At RP3 nodes autodetection all payload slots are marked for control usage.

XXV.<empty>

XXVI.MHA or any other antenna line device capable that is shared between 2 FR:s must not have different technology as radio masters. Rationale: The recovery and alarms handling would become unspecified.

XXVII.Pipes of Remote islands of more than 200 meters distance can not reside in same sector. The mobiles start have issues with incorrect radio propagation delays.

XXVIII.The 2G technology Air interface timing must be aligned according to legacy BTS products, like 2G ultrasite and FlexiEDGE BTSs so that unified Air interface timing is possible. Then common BCCH and multi BCF features can work.

See the attached calculations:

• The capacity critical cases are the Multiradio configurations with wide LTE bandwidth– A separate RP3-01 from both 2G and LTE System Modules to the 3-pipe

Module is proposed.

– For higher LTE capacity cases (e.g chaining and LTE Uplink diversity), 6 Gbit/s RP3-01 is proposed

• Single fiber RP3-01 Multiradio connections are capacity limited

Flexi Multiradio BTS GSM/EDGE Co-SitingCo-Siting with existing BTS Types• Flexi Multiradio BTS is a part of the Flexi platform

– Fully compatible with the Flexi casings, cabinets and conversion/installation kits

– Complies with the Flexi power modules and NSN power systems for Flexi

– Flexi EDGE transmission plug-in units can be used within the Flexi MR system module

– Compatible with the Flexi alarm extension modules (FSEB)

• Radio Module is compatible with:

– ESMx 2G System Module

– Rel’2 WCDMA System Module

– Flexi and Ultrasite antenna line

• Co-siting is supported with: UltraSite and Flexi System modules

– Co-siting with BTSplus is planned in RG20


• Flexi Multiradio can be used as an expansion BTS to existing Flexi EDGE and UltraSite BTSs and allows the operators to create an effective and flexible GSM / EDGE, WCDMA / HSPA, LTE site

• Multiradio Modules can be installed inside UltraSite cabinets in space-limited sites to expand GSM / EDGE capacity or to be stacked on top of existing Flexi EDGE BTS for capacity expansion and evolution to future technologies

• The BTS types are synchronized for seamless co-siting with Multi BCF / common BCCH

• Operator can flexibly migrate to WCDMA / LTE using the same RF Modules, antennas and feeders

• Transmission can be aggregated between the BTS types so as there is only one single connection to existing transmission equipment
