name: FRC
full_form: Fixed Reference Channel
context: The purpose of these tests is to verify the closed loop rank-four performance with wideband precoding with 4Tx and 4Rx under CA. For CA with 2 DL CCs, the requirements are specified in Table 8.13.2.1.4-3, based on single carrier requirement specified in Table 8.13.2.1.4-2, with the addition of the parameters in Table 8.13.2.1.4-1 and the downlink physical channel setup according to Annex C.3.2. The test coverage for different number of component carriers is defined in 8.1.2.4. Table 8.13.2.1.4-1: Test Parameters for Multi-Layer Spatial Multiplexing (FRC) for CA Table 8.13.2.1.4-2: Single carrier performance for multiple CA configurations Table 8.13.2.1.4-3: Minimum performance (FRC) based on single carrier performance for CA with 2 DL CCs
description: The Fixed Reference Channel (FRC) is a standardized channel configuration used in the context of Evolved Universal Terrestrial Radio Access (E-UTRA) for testing and verifying the performance of user equipment (UE) under specific conditions, such as Carrier Aggregation (CA) with multiple downlink component carriers. It serves as a reference point for evaluating the minimum requirements for multi-layer spatial multiplexing in various CA configurations.
explanation: FRC is classified as a Channel because it refers to a predefined setup or configuration used for testing and measuring the performance of UE radio transmission and reception, specifically in the context of E-UTRA and CA scenarios. The mention of 'channel' in this context aligns with the definition of a communication path or medium through which data is transmitted between network elements.
