1 Introduction This document provides the list of feature candidates for the LTE Radio Access System Release TD-LTE 18SP. The scope of the document includes evolved NodeB (eNB) and Transmission. The LTE is managed with the NetAct Operations Support System (OSS) and its interfaces with Packet Switched (PS) Core Networks (CN) over the S1 interface. Operation Mediation Subsystem (OMS) is used to aggregate O&M traffic and mediate data format towards the NetAct. OMS is usually located at the NetAct. The LTE Flexi Multiradio BTS functionality is implemented in compliance with the 3GPP interface specification baseline 3GPP Rel-11 March 2014. There may be changes to the final solutions due to the final release definition process and 3GPP's standardization changes. This document covers only Nokia's LTE RAN level issues and the high level dependencies for the Core Network, WCDMA, GSM system and Mobile Station support. The Flexi Multiradio BTS functionality may not work if the support in one or multiple other network elements, e.g. eNode Bs, UEs, MME, S-GW, eSMLC, MSC, BTS, Node B etc is not provided. The UE dependency is outlined in the SW dependencies field ‘UE’. The other RAT dependencies are outlined in the field ‘dependencies to other RATs’. The core network dependencies to EPC are outlined in the fields ‘MME’ and ‘S-GW’. In the fields ‘BTS Flexi’ for FSMD/E and ‘BTS Flexi 10’ for FSMF family the support of the feature is indicated with release name; blank means not supported. In the field ‘HW requirements’ it will be indicated if the feature requires additionally a specific HW in RAN LTE portfolio. It is left blank if the feature describes a HW item itself or has no specific requirements. The Flexi Multiradio BTS functionality may rely on the activation of other eNode B features. This feature interdependency is outlined in the field ‘interdependencies between Features’. IOTs with other network elements, e.g. eNode Bs, MME, S-GW, eSMLC, MSC, BTS, Node B etc., UEs or applications have to be conducted well in advance in order to ensure the interoperability with other network elements on protocol level. Such testing need to be agreed with NSN IOT department according IOT standard process. 3GPP has not defined the interworking of algorithms, i.e. KPI may depend on multi-vendor scenarios. The actual performance of the feature in field will depend on several external factors e.g. radio condition, antenna configuration, UE location, UE speed, cell load, transport network dimensioning, etc.

3 BTS Site Solution 3.1.1 Nokia CPRI RRH/RFM chaining Unique ID: 2541 Short Description: This feature introduces RRH/RFM chaining functionality based on Nokia CPRI interface standard for Flexi 10 FDD and AirScale System Module.

Benefits for the Customer: Several RRHs or RFMs configured in Nokia CPRI chain topology can be connected to the Flexi 10 FDD or AirScale System Module. It helps to minimize the length of optical lines needed to connect RRHs or RFMs installed in different locations (e.g. roadside coverage, indoor applications, etc.). RRH/RFM chaining feature allows Mobile Operator to decrease CAPEX and OPEX for dark fibers in the front-haul network. Functional Description: This LTE2541 feature is a generic feature which introduces RRH/RFM chain connection type in both LTE-FDD and LTE-TDD domains based on Nokia CPRI interface standard. Supported eNodeB configurations with Nokia CPRI RRH/RFM chaining are described by dedicated eNodeB configuration features e.g. LTE3843: FDD CPRI chaining / dual carrier configs on Airscale for LTE-FDD, etc. LTE2541 Nokia CPRI RRH/RFM chaining feature is applicable for: • Flexi 10 FDD (FSMF) in FDD-LTE • AirScale System Module in FDD-LTE and TDD-LTE The max number ("n") of RRH/RFM connected in one chain depends on HW/SW capabilities of System Module and considered RRH/RFM and it is specified separately for each RRH/RFM type. (Internal Note: the max number ("n") of RRH/RFM connected in one chain to be specified in LTE2541 CFAM). For example, n=4 (max chain size), the chain will look as follow: System_Module RRH1 RRH2 RRH3 RRH4. In distributed BTS configurations, the maximum fiber length to last radio unit in chain is defined by feature LTE614:Distributed Site in case of Nokia CPPI RRH/RFMs connected to entire eNodeB. For example, for maximum fiber length to last radio unit in chain=23km, n=3 and chain SM RRH1 RRH2 RRH3, the sum of

Combined_fibre_optic_cable_length = + + should be lower or equal to 23 km. Single band or dual-band RRH/RFM can be connected in one chain. I/Q compression (IQC) is allowed in the Nokia CPRI chain if all RRHs/RFMs in chain support IQC. This feature requires direct passive optical connection in the chain. HW Requirements: Nokia RRH/RFM that support Nokia CPRI dialect are required.

Interdependencies between Features: RF sharing (RFS) is not supported simultaneously with LTE2541 Nokia CPRI RRH/RFM chaining feature. TD-LTE RL Software Dependencies: LTE BTS Flexi BTS Flexi 10 10 Indoor
