3GPP TSG-RAN WG4 Meeting # 95-e Electronic Meeting, 25 May 5 June, 2020 R4-200XXXX WF on MSR base station TC reduction. Ericsson
Background In RAN#4-92, a discussion on the need for a test configuration reduction for EMC was proposed by Ericsson in R4-1908856. The main argument for the proposed discussion has been the increase in the number of test configurations associated to various possible RAT combinations. Companies following EMC discussion have expressed interest on understanding the scope of the proposal and the potential benefits of implementing EMC test configuration reduction.
WF Agreement (1) Current testing of EMC requirements as specified in standards such as TS 37.113 [1] (MSR BS) is increasingly complex and considers many test configurations, due to various possible RAT combinations, which might lead to increasing testing costs. Alternatives to be considered for achieving a test configuration reduction can be: Option 1: To reuse current capability sets and existing test configurations. Ericsson has provided a proposal using TC21 and TC22 (Preferred alternative) Option 2: To define new capability sets and test configurations. This option requires coordination with the RF area. Option 3: Keep the current capability sets and test configurations Other options are not precluded. Definition of the alternative to be considered shall consider (but it is limited to the following): The mechanism to choose the highest emission when testing only some of the RATs available in the BS under test. Definition of the alternative to achieve test configuration shall assure that the test coverage is not limited. Alternative to achieve test configuration shall take into account the specificities of the BS design.
WF Agreement (2) Companies interested on the EMC discussion shall provide elements analyzing the existence of redundancies in the Capability Sets (CS) used for EMC testing in MSR and the amount of test time reduction achieved. Companies interested on the EMC discussion shall provide input in the identification of the requirements to consider for both Immunity and Emmission testing and the amount of test time reduction acheived. Companies interested on the EMC discussion shall provide their opinion on the best way to proceed with the discussion of the test configuration reduction. Options can be: Direct modifications to the TS on conformance Open a WI targeting Release 17. Other options are not precluded.
